To: dev
The "lib" directory is getting very crowded, with both general libs and
poll mode drivers in it. This patch set proposes to move the PMDs out of the
lib folder and to put them in a separate "pmds" folder. This should help
with code browse-ability as the number of libs, and pmds increases.
Comments or objections?
Bruce Richardson (2):
pmds: Use relative rather than absolute paths
pmds: move pmds from lib to separate pmd dir

* [dpdk-dev] [RFC PATCH 1/2] pmds: Use relative rather than absolute paths

In the Makefiles for the PMDs, the paths to the files are often
specified using the full path from $(RTE_SDK) variable. These paths can
be shortened, and make more flexible in case of a future path change by
specifying the paths using $(SRCDIR) instead.

But at the end they are also libraries. What about something like:
* libs/core <= fundamental libraries (eal, mbuf rings...)
* libs/pmds <= all pmds
And other feature-group oriented, higher level lib, directories (not
sure right now how to better classify them right now):
* libs/processing <= packet processing
* libs/utils
...
Just an idea.

Apologies, but the second patch of the proposed set failed because it was too
big. However, I'm confident that people can make a pretty good guess as to what
it actually contained based on the summary below. :-)

Yes, they are all just libs, so we could make "pmds" be a sub-dir of the lib
folder. I prefer the shorter path myself, but if others want a multi-level
hierarchy it's no big deal.
For the other libs, I'm not sure we need to split them up, and I also think
that trying to divide them into categories - and what those categories should
be could - cause endless discussion. However, maybe I'm overly pessimistic... :-)

I like the dpdk/pmds as dpdk/lib/pmds is a bit longer, but I also see if
we want to move the pmds to other repo(s) in the future it would be easier
(I think) to have the subtree at the top. To me pmds are not really
libraries as I think of libc or libcrypto or something along that path.
The PMDs need to be plug able and they maybe more like loadable modules
then libraries in the future.

I agree with Bruce here we just need the PMDS split out for now.

However, if in future we might want to split out the other libs into categories,
it may make more sense to have the pmds as a subfolder lib.
I still think I prefer having pmds at the top level of the tree, though.

When someone is looking for a driver implementation and check what is done in
DPDK, it will be easier to open a directory named "drivers" rather than "pmds".
I agree that they are not really libs as they are used as plugins. So they
deserve a separate directory at the top level.
Moreover, I suspect that the dataplane managed by DPDK can be extended to
crypto and storage devices in the near future.
So, I would suggest
drivers/net
drivers/crypto
drivers/storage
This kind of split could help to clearly define the responsibilities of some
new git subtrees.
Don't you think we could also remove the librte_pmd_ prefix for these new
directories?
Ultimately, I'd like to see the subdirectories for e1000, ixgbe and i40e renamed
to base/.

To: dev
As covered previously in an RFC, this patchset creates a new top-level drivers
folder and moves the PMDs into it. Moving the drivers involves a lot of code -
too big for a single patch, so each driver is moved separately in its own patchset.
Some doc updates are done as part of this patchset - based on the results of
git grep, but may be incomplete, so flag any doc areas that I may have missed,
please.

In the Makefiles for the PMDs, the paths to the files are often
specified using the full path from $(RTE_SDK) variable. These paths can
be shortened, and make more flexible in case of a future path change by
specifying the paths using $(SRCDIR) instead.

Add a new top-level drivers directory to which all PMDs will be moved
for easier maintenance of both lib folder and drivers themselves. This
new directory is a dependency of all the apps in the app folder, so
the makefiles for each app are updated.

- * be handled with the expected latency and this may cause the link status to be

+ * "Intel 82576 GbE Controller Datasheet" - Revision 2.45 October 2009
+ *
+ * Principles:
+ * The source and destination IP addresses of the IP header and the source and
+ * destination ports of TCP/UDP headers, if any, of received packets are hashed
+ * against a configurable random key to compute a 32-bit RSS hash result.
+ * The seven (7) LSBs of the 32-bit hash result are used as an index into a
+ * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
+ * RSS output index which is used as the RX queue index where to store the
+ * received packets.
+ * The following output is supplied in the RX write-back descriptor:
+ * - 32-bit result of the Microsoft RSS hash function,
+ * - 4-bit RSS type field.

- * TBI_ACCEPT macro definition:
- *
- * This macro requires:
- * adapter = a pointer to struct e1000_hw
- * status = the 8 bit status field of the Rx descriptor with EOP set
- * error = the 8 bit error field of the Rx descriptor with EOP set
- * length = the sum of all the length fields of the Rx descriptors that
- * make up the current frame
- * last_byte = the last byte of the frame DMAed by the hardware
- * max_frame_length = the maximum frame length we want to accept.
- * min_frame_length = the minimum frame length we want to accept.
- *
- * This macro is a conditional that should be used in the interrupt
- * handler's Rx processing routine when RxErrors have been detected.
- *
- * Typical use:
- * ...
- * if (TBI_ACCEPT) {
- * accept_frame = true;
- * e1000_tbi_adjust_stats(adapter, MacAddress);
- * frame_length--;
- * } else {
- * accept_frame = false;
- * }
- * ...

- * Receive Side Scaling (RSS).
- * See section 7.1.1.7 in the following document:

- *
- * Principles:
- * The source and destination IP addresses of the IP header and the source and
- * destination ports of TCP/UDP headers, if any, of received packets are hashed
- * against a configurable random key to compute a 32-bit RSS hash result.
- * The seven (7) LSBs of the 32-bit hash result are used as an index into a
- * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
- * RSS output index which is used as the RX queue index where to store the
- * received packets.
- * The following output is supplied in the RX write-back descriptor:
- * - 32-bit result of the Microsoft RSS hash function,
- * - 4-bit RSS type field.

+ * this state is for the system to make the connect() call for the
+ * mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection. It will
+ * post a connect message with no specified destination and will
+ * wait for a reply from the other side of the mailbox. This state
+ * is exited when either a connect with the local mailbox as the
+ * destination is received or when a data message is received with
+ * a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ * entity and the remote. It will fall back to connect in the event of
+ * receiving either an error message, or a disconnect message. It will
+ * transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ * the connection. It will do so at the first point where it knows
+ * that the remote endpoint is either done sending, or when the
+ * remote endpoint has fallen back into connect.

+ * 0xC: Connect header - used to establish connection
+ * 0xD: Disconnect header - used to tear down a connection
+ * 0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ * Tail index actually consists of two parts. The MSB of
+ * the head is a loop tracker, it is 0 on an even numbered
+ * loop through the FIFO, and 1 on the odd numbered loops.
+ * To get the actual mailbox offset based on the tail it
+ * is necessary to add bit 3 to bit 0 and clear bit 3. This
+ * gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ * Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ * The maximum message size is provided during connect to avoid
+ * jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ * The error number provides a indication of the type of error

- * read the mailbox or write any data. The only means of exiting
- * this state is for the system to make the connect() call for the
- * mailbox, it will then transition to the connect state.
- * Connect: In this state the mailbox is seeking a connection. It will
- * post a connect message with no specified destination and will
- * wait for a reply from the other side of the mailbox. This state
- * is exited when either a connect with the local mailbox as the
- * destination is received or when a data message is received with
- * a valid sequence number.
- * Open: In this state the mailbox is able to transfer data between the local
- * entity and the remote. It will fall back to connect in the event of
- * receiving either an error message, or a disconnect message. It will
- * transition to disconnect on a call to disconnect();
- * Disconnect: In this state the mailbox is attempting to gracefully terminate
- * the connection. It will do so at the first point where it knows
- * that the remote endpoint is either done sending, or when the
- * remote endpoint has fallen back into connect.

- *
- * The layout above describes the format for the header used in the PF/VF
- * mailbox. The header is broken out into the following fields:
- * Type: There are 4 supported message types
- * 0x8: Data header - used to transport message data
- * 0xC: Connect header - used to establish connection
- * 0xD: Disconnect header - used to tear down a connection
- * 0xE: Error header - used to address message exceptions
- * Tail: Tail index for local FIFO
- * Tail index actually consists of two parts. The MSB of
- * the head is a loop tracker, it is 0 on an even numbered
- * loop through the FIFO, and 1 on the odd numbered loops.
- * To get the actual mailbox offset based on the tail it
- * is necessary to add bit 3 to bit 0 and clear bit 3. This
- * gives us a valid range of 0x1 - 0xE.
- * Head: Head index for remote FIFO
- * Head index follows the same format as the tail index.
- * Rsvd0: Reserved 0 portion of the mailbox header
- * CRC: Running CRC for all data since connect plus current message header
- * Size: Maximum message size - Applies only to connect headers
- * The maximum message size is provided during connect to avoid
- * jamming the mailbox with messages that do not fit.
- * Err_no: Error number - Applies only to error headers
- * The error number provides a indication of the type of error
- * experienced.

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of these
+ * opcodes. The VF driver must first validate the API version of the PF driver,
+ * then request a reset, then get resources, then configure queues and
+ * interrupts. After these operations are complete, the VF driver may start
+ * its queues, optionally add MAC and VLAN filters, and process traffic.

-/* Description:
- * This header file describes the VF-PF communication protocol used
- * by the various i40e drivers.
- *
- * Admin queue buffer usage:
- * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
- * flags, retval, datalen, and data addr are all used normally.
- * Firmware copies the cookie fields when sending messages between the PF and
- * VF, but uses all other fields internally. Due to this limitation, we
- * must send all messages as "indirect", i.e. using an external buffer.
- *
- * All the vsi indexes are relative to the VF. Each VF can have maximum of
- * three VSIs. All the queue indexes are relative to the VSI. Each VF can
- * have a maximum of sixteen queues for all of its VSIs.
- *
- * The PF is required to return a status code in v_retval for all messages
- * except RESET_VF, which does not require any response. The return value is of
- * i40e_status_code type, defined in the i40e_type.h.
- *
- * In general, VF driver initialization should roughly follow the order of these
- * opcodes. The VF driver must first validate the API version of the PF driver,
- * then request a reset, then get resources, then configure queues and
- * interrupts. After these operations are complete, the VF driver may start
- * its queues, optionally add MAC and VLAN filters, and process traffic.

+/*
+ * The following is a brief description of the error categories used by the
+ * ERROR_REPORT* macros.
+ *
+ * - IXGBE_ERROR_INVALID_STATE
+ * This category is for errors which represent a serious failure state that is
+ * unexpected, and could be potentially harmful to device operation. It should
+ * not be used for errors relating to issues that can be worked around or
+ * ignored.
+ *
+ * - IXGBE_ERROR_POLLING
+ * This category is for errors related to polling/timeout issues and should be
+ * used in any case where the timeout occured, or a failure to obtain a lock, or
+ * failure to receive data within the time limit.
+ *
+ * - IXGBE_ERROR_CAUTION
+ * This category should be used for reporting issues that may be the cause of
+ * other errors, such as temperature warnings. It should indicate an event which
+ * could be serious, but hasn't necessarily caused problems yet.
+ *
+ * - IXGBE_ERROR_SOFTWARE
+ * This category is intended for errors due to software state preventing
+ * something. The category is not intended for errors due to bad arguments, or
+ * due to unsupported features. It should be used when a state occurs which
+ * prevents action but is not a serious issue.
+ *
+ * - IXGBE_ERROR_ARGUMENT
+ * This category is for when a bad or invalid argument is passed. It should be
+ * used whenever a function is called and error checking has detected the
+ * argument is wrong or incorrect.
+ *
+ * - IXGBE_ERROR_UNSUPPORTED
+ * This category is for errors which are due to unsupported circumstances or
+ * configuration issues. It should not be used when the issue is due to an
+ * invalid argument, but for when something has occurred that is unsupported
+ * (Ex: Flow control autonegotiation or an unsupported SFP+ module.)

+ * "Intel 82599 10 GbE Controller Datasheet" - Revision 2.1 October 2009
+ *
+ * Principles:
+ * The source and destination IP addresses of the IP header and the source
+ * and destination ports of TCP/UDP headers, if any, of received packets are
+ * hashed against a configurable random key to compute a 32-bit RSS hash result.
+ * The seven (7) LSBs of the 32-bit hash result are used as an index into a
+ * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
+ * RSS output index which is used as the RX queue index where to store the
+ * received packets.
+ * The following output is supplied in the RX write-back descriptor:
+ * - 32-bit result of the Microsoft RSS hash function,
+ * - 4-bit RSS type field.

- * The following is a brief description of the error categories used by the
- * ERROR_REPORT* macros.
- *
- * - IXGBE_ERROR_INVALID_STATE
- * This category is for errors which represent a serious failure state that is
- * unexpected, and could be potentially harmful to device operation. It should
- * not be used for errors relating to issues that can be worked around or
- * ignored.
- *
- * - IXGBE_ERROR_POLLING
- * This category is for errors related to polling/timeout issues and should be
- * used in any case where the timeout occured, or a failure to obtain a lock, or
- * failure to receive data within the time limit.
- *
- * - IXGBE_ERROR_CAUTION
- * This category should be used for reporting issues that may be the cause of
- * other errors, such as temperature warnings. It should indicate an event which
- * could be serious, but hasn't necessarily caused problems yet.
- *
- * - IXGBE_ERROR_SOFTWARE
- * This category is intended for errors due to software state preventing
- * something. The category is not intended for errors due to bad arguments, or
- * due to unsupported features. It should be used when a state occurs which
- * prevents action but is not a serious issue.
- *
- * - IXGBE_ERROR_ARGUMENT
- * This category is for when a bad or invalid argument is passed. It should be
- * used whenever a function is called and error checking has detected the
- * argument is wrong or incorrect.
- *
- * - IXGBE_ERROR_UNSUPPORTED
- * This category is for errors which are due to unsupported circumstances or
- * configuration issues. It should not be used when the issue is due to an
- * invalid argument, but for when something has occurred that is unsupported
- * (Ex: Flow control autonegotiation or an unsupported SFP+ module.)

- * Principles:
- * The source and destination IP addresses of the IP header and the source

- * hashed against a configurable random key to compute a 32-bit RSS hash result.
- * The seven (7) LSBs of the 32-bit hash result are used as an index into a
- * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
- * RSS output index which is used as the RX queue index where to store the
- * received packets.
- * The following output is supplied in the RX write-back descriptor:
- * - 32-bit result of the Microsoft RSS hash function,
- * - 4-bit RSS type field.

Two reasons why I didn't create the "net" subfolder:
1. I initally forgot to consider it :-(
2. While we may at some future point have other device driver types, are we really
needing to start categorising PMDs at this point?
As for the base driver part, I was viewing that as a something that should be
a separate patch set, since it's unrelated to moving things to the drivers
subdir.
I realise now, I should have replied to the original email with these points
before diving into the new patchset. My bad...

I understand your points and I partially agree.
However, file moves may be perturbing because it change habits
and may complicate a bit the git history browsing.
So I think it's better to minimize such moves and do altogether.

Ok. I'll see about renaming the base code directories as part of the overall
move process [Unless there are objections from any of the driver maintainers].
As for drivers vs drivers/net, I suppose there is no real difference in what
the path actually is, so I can make that change too. However, I still think I
prefer the shorter path. Anyone else any opinions on this [before I start
reworking this again]?

A further thought on the splitting up of drivers. What about devices which provide
more than one type of offload, how would the PMD for such a device be classified?

Hi Thomas,
a specific question on how you want the rename of the "base" driver directories.
Can I take it from your question that you want the base driver renaming to be
merged into a single commit with the rest of the move for the driver? For example,
as part of the patch move from "lib/librte_pmd_e1000" to "drivers/net/e1000" we
also rename the "e1000" subdir to "base".
The slight problem with this approach - of trying to do both moves in a single
patch is that the rename of the subdirectory "e1000" involves changes to other
files in the librte_pmd_e1000 directory which are being moved, so we can't
have a clean patch that just moves files and doesn't touch those files which are
being moved. Therefore, from a patch cleanliness point of view, the renames
to the base directory should be a separate patch, which I can make part of this
series.

Yes, to minimize number of patches moving files (and breaking history for
some tools).

The changes are only in Makefile and include lines, right?
I think it's not a big deal to have small changes. But maybe it will make
difficult to read the move with some tools.
Feel free to adopt the solution you prefer if nobody else has an experienced
opinion.

Other projects (e.g. Linux) would have the same classification problem.
How do they solve it? Is it possible to split code in different directories
or different drivers?

I would tend to agree that we are as well merging the commits into one,
but I just want to be sure about it before I go doing the work and respinning the
patches. :-)
So, any objections to doing 2 moves in one patch, please raise them soon, i.e. today.

No idea, possibly some of the resident linux kernel experts on-list can inform us.
However, this is likely a solved problem, so I'm going to rework the patchset to
use drivers/net for now, and thereby allow future-proofing for other device types.

As covered previously in an RFC, this patchset creates a new top-level drivers
folder and moves the PMDs into it. Moving the drivers involves a lot of code -
too big for a single patch, so each driver is moved separately in its own patchset.
Some doc updates are done as part of this patchset - based on the results of
git grep, but may be incomplete, so flag any doc areas that I may have missed,
please.
Changes in V2:
* use drivers/net rather than just drivers
* rename e1000, ixgbe, i40e and vmxnet3 base driver code dir to "base"
* update copyright dates to 2015 on modified files
Bruce Richardson (19):
pmds: Use relative rather than absolute paths
drivers: create drivers and drivers/net directory
af_packet: move af_packet pmd to drivers/net directory
bond: Move bonded ethdev pmd to drivers/net
e1000: move e1000 pmd to drivers/net directory
enic: move enic PMD to drivers/net directory
fm10k: move fm10k PMD to drivers/net directory
i40e: move i40e PMD to drivers/net directory
ixbge: move ixgbe PMD to drivers/net directory
mlx4: move mlx4 PMD to drivers/net directory
null pmd: move null PMD to drivers/net directory
pcap: move pcap pmd to drivers/net
ring pmd: move ring PMD to the drivers directory
virtio: move virtio PMD to drivers/net
xmvnet3: move vmxnet3 PMD to drivers/net
xenvirt: move xenvirt PMD to drivers/net
maintainers: update maintainers with driver paths
doc: update GSG doc for new drivers subdirectory
doc: update source organisation text for drivers

* [dpdk-dev] [PATCH v2 01/19] pmds: Use relative rather than absolute paths
2015-05-15 15:56 ` [dpdk-dev] [PATCH v2 " Bruce Richardson
@ 2015-05-15 15:56 ` Bruce Richardson
2015-05-15 15:56 ` [dpdk-dev] [PATCH v2 02/19] drivers: create drivers and drivers/net directory Bruce Richardson
` (18 subsequent siblings)
19 siblings, 0 replies; 74+ messages in thread
From: Bruce Richardson @ 2015-05-15 15:56 UTC (permalink / raw)
To: dev
In the Makefiles for the PMDs, the paths to the files are often
specified using the full path from $(RTE_SDK) variable. These paths can
be shortened, and make more flexible in case of a future path change by
specifying the paths using $(SRCDIR) instead.

From: Bruce Richardson @ 2015-05-15 15:56 UTC (permalink / raw)
To: dev
Add a new top-level "drivers" directory to which all PMDs will be moved
for easier maintenance of both lib folder and drivers themselves. This
new directory is a dependency of all the apps in the app folder, so
the makefiles for each app are updated.
To the new top-level directory add a "net" subdirectory to classify
more specifically our existing PMDs as ethernet drivers

+ * The seven (7) LSBs of the 32-bit hash result are used as an index into a
+ * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
+ * RSS output index which is used as the RX queue index where to store the
+ * received packets.
+ * The following output is supplied in the RX write-back descriptor:
+ * - 32-bit result of the Microsoft RSS hash function,
+ * - 4-bit RSS type field.

- * status = the 8 bit status field of the Rx descriptor with EOP set
- * error = the 8 bit error field of the Rx descriptor with EOP set
- * length = the sum of all the length fields of the Rx descriptors that

- * last_byte = the last byte of the frame DMAed by the hardware
- * max_frame_length = the maximum frame length we want to accept.
- * min_frame_length = the minimum frame length we want to accept.
- *
- * This macro is a conditional that should be used in the interrupt

- * Read the PHY register at offset and store the retrieved information in
- * data, or write data to PHY register at offset. Note the procedure to
- * access the PHY wakeup registers is different than reading the other PHY
- * registers. It works as such:
- * 1) Set 769.17.2 (page 769, register 17, bit 2) = 1
- * 2) Set page to 800 for host (801 if we were manageability)
- * 3) Write the address using the address opcode (0x11)
- * 4) Read or write the data using the data opcode (0x12)
- * 5) Restore 769.17.2 to its original value
- *
- * Steps 1 and 2 are done by e1000_enable_phy_wakeup_reg_access_bm() and
- * step 5 is done by e1000_disable_phy_wakeup_reg_access_bm().
- *
- * Assumes semaphore is already acquired. When page_set==true, assumes
- * the PHY page is set to BM_WUC_PAGE (i.e. a function in the call stack
- * is responsible for calls to e1000_[enable|disable]_phy_wakeup_reg_bm()).

- * RSS output index which is used as the RX queue index where to store the
- * received packets.
- * The following output is supplied in the RX write-back descriptor:
- * - 32-bit result of the Microsoft RSS hash function,
- * - 4-bit RSS type field.

+ * this state is for the system to make the connect() call for the
+ * mailbox, it will then transition to the connect state.
+ * Connect: In this state the mailbox is seeking a connection. It will
+ * post a connect message with no specified destination and will
+ * wait for a reply from the other side of the mailbox. This state
+ * is exited when either a connect with the local mailbox as the
+ * destination is received or when a data message is received with
+ * a valid sequence number.
+ * Open: In this state the mailbox is able to transfer data between the local
+ * entity and the remote. It will fall back to connect in the event of
+ * receiving either an error message, or a disconnect message. It will
+ * transition to disconnect on a call to disconnect();
+ * Disconnect: In this state the mailbox is attempting to gracefully terminate
+ * the connection. It will do so at the first point where it knows
+ * that the remote endpoint is either done sending, or when the
+ * remote endpoint has fallen back into connect.

+ * Type: There are 4 supported message types
+ * 0x8: Data header - used to transport message data
+ * 0xC: Connect header - used to establish connection
+ * 0xD: Disconnect header - used to tear down a connection
+ * 0xE: Error header - used to address message exceptions
+ * Tail: Tail index for local FIFO
+ * Tail index actually consists of two parts. The MSB of
+ * the head is a loop tracker, it is 0 on an even numbered
+ * loop through the FIFO, and 1 on the odd numbered loops.
+ * To get the actual mailbox offset based on the tail it
+ * is necessary to add bit 3 to bit 0 and clear bit 3. This
+ * gives us a valid range of 0x1 - 0xE.
+ * Head: Head index for remote FIFO
+ * Head index follows the same format as the tail index.
+ * Rsvd0: Reserved 0 portion of the mailbox header
+ * CRC: Running CRC for all data since connect plus current message header
+ * Size: Maximum message size - Applies only to connect headers
+ * The maximum message size is provided during connect to avoid
+ * jamming the mailbox with messages that do not fit.
+ * Err_no: Error number - Applies only to error headers
+ * The error number provides a indication of the type of error

- * Closed: This state represents a mailbox that is in a standby state
- * with interrupts disabled. In this state the mailbox should not
- * read the mailbox or write any data. The only means of exiting
- * this state is for the system to make the connect() call for the
- * mailbox, it will then transition to the connect state.
- * Connect: In this state the mailbox is seeking a connection. It will
- * post a connect message with no specified destination and will
- * wait for a reply from the other side of the mailbox. This state
- * is exited when either a connect with the local mailbox as the
- * destination is received or when a data message is received with
- * a valid sequence number.
- * Open: In this state the mailbox is able to transfer data between the local
- * entity and the remote. It will fall back to connect in the event of
- * receiving either an error message, or a disconnect message. It will
- * transition to disconnect on a call to disconnect();
- * Disconnect: In this state the mailbox is attempting to gracefully terminate
- * the connection. It will do so at the first point where it knows
- * that the remote endpoint is either done sending, or when the
- * remote endpoint has fallen back into connect.

- *
- * The layout above describes the format for the header used in the PF/VF
- * mailbox. The header is broken out into the following fields:
- * Type: There are 4 supported message types
- * 0x8: Data header - used to transport message data
- * 0xC: Connect header - used to establish connection
- * 0xD: Disconnect header - used to tear down a connection
- * 0xE: Error header - used to address message exceptions
- * Tail: Tail index for local FIFO
- * Tail index actually consists of two parts. The MSB of
- * the head is a loop tracker, it is 0 on an even numbered
- * loop through the FIFO, and 1 on the odd numbered loops.
- * To get the actual mailbox offset based on the tail it
- * is necessary to add bit 3 to bit 0 and clear bit 3. This
- * gives us a valid range of 0x1 - 0xE.
- * Head: Head index for remote FIFO
- * Head index follows the same format as the tail index.
- * Rsvd0: Reserved 0 portion of the mailbox header
- * CRC: Running CRC for all data since connect plus current message header
- * Size: Maximum message size - Applies only to connect headers
- * The maximum message size is provided during connect to avoid
- * jamming the mailbox with messages that do not fit.
- * Err_no: Error number - Applies only to error headers
- * The error number provides a indication of the type of error
- * experienced.

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *

-/* Description:
- * This header file describes the VF-PF communication protocol used
- * by the various i40e drivers.
- *
- * Admin queue buffer usage:
- * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
- * flags, retval, datalen, and data addr are all used normally.
- * Firmware copies the cookie fields when sending messages between the PF and
- * VF, but uses all other fields internally. Due to this limitation, we
- * must send all messages as "indirect", i.e. using an external buffer.
- *
- * All the vsi indexes are relative to the VF. Each VF can have maximum of
- * three VSIs. All the queue indexes are relative to the VSI. Each VF can
- * have a maximum of sixteen queues for all of its VSIs.
- *
- * The PF is required to return a status code in v_retval for all messages
- * except RESET_VF, which does not require any response. The return value is of
- * i40e_status_code type, defined in the i40e_type.h.
- *
- * In general, VF driver initialization should roughly follow the order of these
- * opcodes. The VF driver must first validate the API version of the PF driver,
- * then request a reset, then get resources, then configure queues and
- * interrupts. After these operations are complete, the VF driver may start
- * its queues, optionally add MAC and VLAN filters, and process traffic.

+ * The following is a brief description of the error categories used by the

+ *
+ * - IXGBE_ERROR_INVALID_STATE
+ * This category is for errors which represent a serious failure state that is
+ * unexpected, and could be potentially harmful to device operation. It should
+ * not be used for errors relating to issues that can be worked around or
+ * ignored.
+ *
+ * - IXGBE_ERROR_POLLING
+ * This category is for errors related to polling/timeout issues and should be
+ * used in any case where the timeout occured, or a failure to obtain a lock, or
+ * failure to receive data within the time limit.
+ *
+ * - IXGBE_ERROR_CAUTION
+ * This category should be used for reporting issues that may be the cause of
+ * other errors, such as temperature warnings. It should indicate an event which
+ * could be serious, but hasn't necessarily caused problems yet.
+ *
+ * - IXGBE_ERROR_SOFTWARE
+ * This category is intended for errors due to software state preventing
+ * something. The category is not intended for errors due to bad arguments, or
+ * due to unsupported features. It should be used when a state occurs which
+ * prevents action but is not a serious issue.
+ *
+ * - IXGBE_ERROR_ARGUMENT
+ * This category is for when a bad or invalid argument is passed. It should be
+ * used whenever a function is called and error checking has detected the
+ * argument is wrong or incorrect.
+ *
+ * - IXGBE_ERROR_UNSUPPORTED
+ * This category is for errors which are due to unsupported circumstances or
+ * configuration issues. It should not be used when the issue is due to an
+ * invalid argument, but for when something has occurred that is unsupported
+ * (Ex: Flow control autonegotiation or an unsupported SFP+ module.)

+ * 2) When EOP arrives we just update the cluster's total length and offload
+ * flags and deliver the cluster up to the upper layers. In our case - put it
+ * in the rx_pkts table.
+ *
+ * Returns the number of received packets/clusters (according to the "bulk

- * The following is a brief description of the error categories used by the
- * ERROR_REPORT* macros.
- *
- * - IXGBE_ERROR_INVALID_STATE
- * This category is for errors which represent a serious failure state that is
- * unexpected, and could be potentially harmful to device operation. It should
- * not be used for errors relating to issues that can be worked around or
- * ignored.
- *
- * - IXGBE_ERROR_POLLING
- * This category is for errors related to polling/timeout issues and should be
- * used in any case where the timeout occured, or a failure to obtain a lock, or
- * failure to receive data within the time limit.
- *
- * - IXGBE_ERROR_CAUTION
- * This category should be used for reporting issues that may be the cause of
- * other errors, such as temperature warnings. It should indicate an event which
- * could be serious, but hasn't necessarily caused problems yet.
- *
- * - IXGBE_ERROR_SOFTWARE
- * This category is intended for errors due to software state preventing
- * something. The category is not intended for errors due to bad arguments, or
- * due to unsupported features. It should be used when a state occurs which
- * prevents action but is not a serious issue.
- *
- * - IXGBE_ERROR_ARGUMENT
- * This category is for when a bad or invalid argument is passed. It should be
- * used whenever a function is called and error checking has detected the
- * argument is wrong or incorrect.
- *
- * - IXGBE_ERROR_UNSUPPORTED
- * This category is for errors which are due to unsupported circumstances or
- * configuration issues. It should not be used when the issue is due to an
- * invalid argument, but for when something has occurred that is unsupported
- * (Ex: Flow control autonegotiation or an unsupported SFP+ module.)

- * Receive Side Scaling (RSS)
- * See section 7.1.2.8 in the following document:
- * "Intel 82599 10 GbE Controller Datasheet" - Revision 2.1 October 2009
- *
- * Principles:
- * The source and destination IP addresses of the IP header and the source
- * and destination ports of TCP/UDP headers, if any, of received packets are
- * hashed against a configurable random key to compute a 32-bit RSS hash result.
- * The seven (7) LSBs of the 32-bit hash result are used as an index into a
- * 128-entry redirection table (RETA). Each entry of the RETA provides a 3-bit
- * RSS output index which is used as the RX queue index where to store the
- * received packets.
- * The following output is supplied in the RX write-back descriptor:
- * - 32-bit result of the Microsoft RSS hash function,
- * - 4-bit RSS type field.
- */

From: Bruce Richardson @ 2015-05-15 15:56 UTC (permalink / raw)
To: dev
Move vmxnet3 PMD to drivers/net directory.
As part of the move, rename the "vmxnet3" subdirectory, containing the
original FreeBSD drivers, from "vmxnet3" to the more standard name
"base", to indicate it contains the base drivers used for the
implementation.

+Drivers
+-------
+
+Drivers are special libraries which provide poll-mode driver implementations for
+devices - either hardware devices or pseudo/virtual devices. They are contained
+in the "drivers" subdirectory, classified by type, and each compiles to a
+library with the format "librte_pmd_X.a" where "X" is the driver name.
+
+The drivers directory has a net subdirectory which contains::
+
+ drivers/net
+ +-- af_packet # poll mode driver based on linux af_packet

Move i40e PMD to drivers/net directory.
As part of the move, rename the "i40e" directory, containing the "base
driver" code, from "i40e" to "base".

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of these
+ * opcodes. The VF driver must first validate the API version of the PF driver,
+ * then request a reset, then get resources, then configure queues and
+ * interrupts. After these operations are complete, the VF driver may start
+ * its queues, optionally add MAC and VLAN filters, and process traffic.

-/* Description:
- * This header file describes the VF-PF communication protocol used
- * by the various i40e drivers.
- *
- * Admin queue buffer usage:
- * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
- * flags, retval, datalen, and data addr are all used normally.
- * Firmware copies the cookie fields when sending messages between the PF and
- * VF, but uses all other fields internally. Due to this limitation, we
- * must send all messages as "indirect", i.e. using an external buffer.
- *
- * All the vsi indexes are relative to the VF. Each VF can have maximum of
- * three VSIs. All the queue indexes are relative to the VSI. Each VF can
- * have a maximum of sixteen queues for all of its VSIs.
- *
- * The PF is required to return a status code in v_retval for all messages
- * except RESET_VF, which does not require any response. The return value is of
- * i40e_status_code type, defined in the i40e_type.h.
- *
- * In general, VF driver initialization should roughly follow the order of these
- * opcodes. The VF driver must first validate the API version of the PF driver,
- * then request a reset, then get resources, then configure queues and
- * interrupts. After these operations are complete, the VF driver may start
- * its queues, optionally add MAC and VLAN filters, and process traffic.

Note, due to 2 commits to i40e/base that were merged last night patch 08/19 fails on HEAD.
If we are going to apply this patchset, and I think we should, then we should probably do it sooner rather than later since almost any change to the files in lib will require a respin of the patchset and it is quite large.

Thomas, assuming there are no objections to this patchset, let me know when you
are merging this in if you need another respin of patch 8 (or any other patches)
in the set. I'm not going to respin for every driver change that causes issues,
simply due to the patch sizes.

I'm going to look at applying it shortly.
Don't worry for the rebase, I can manage it.

I wasn't able to apply 05/19. However, since it is simple as it is just
moving files and is likely to have been corrupted in transit. I think
the patch is a good idea and I am confident your rebasing will catch any
problems.

Why drivers are a dependency of every apps?
Some of them don't even include rte_ethdev.h.

Good point. I just got a broken build initially in the apps with missing dependencies, so I made the change so that dependencies were the same as before.
Looking at things, I imagine test-pmd and test-pipeline depend upon the drivers since they do packet IO, and the test app will depend on it as it has unit tests for the bond-ethdev driver.
Dump-cfg and the test-acl app should not have a dependency on the driver, I imagine.
It appears that the cmdline-test app is missing a DEPDIRS-y line, but it probably should depend on the libs, right?

Yes, I was wondering about that. However, this wasn't a driver I was familiar with and its origins, so I left it as-is.

Please go ahead with the renaming.

Applied with the changes discussed in this thread.
Some patches were split/merge to make each driver move more atomic.

There's a way to do source movements with git such that history

I don't see anything special here:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5a2cc190eb3fe
It doesn't seem different of
http://dpdk.org/browse/dpdk/commit/?id=98a1f3776fc9a3de442
By the way, what do you mean by "history remains"?
Are you thinking about git log --follow which is known to be a hack?
http://permalink.gmane.org/gmane.comp.version-control.git/147089
My understanding is that file history doesn't fit well with git:
http://article.gmane.org/gmane.comp.version-control.git/217
> Please make sure to use that practice here too.
The change was applied before you sent this message:
http://dpdk.org/ml/archives/dev/2015-May/018064.html
But I'm still interested about best practices.
