[dpdk-dev] [PATCH 00/12] Remove cryptodev driver

[dpdk-dev] [PATCH 00/12] Remove cryptodev driver

[Pablo de Lara]

Following the same aproach taken for ethdev, this patch series
removes the PCI specific structure cryptodev driver from rte_cryptodev.

The patchset makes the following changes:

- Moves the virtual and PCI device specific functions to separate files,
  so other cryptodev header files contain only device type agnostic functions.

- Modifies device info retrieval function to set the driver name for all devices
  and set PCI info inside PCI device PMDs

- Removes cryptodev driver structure from cryptodev library and drivers
  that were using it (QAT and dpaa2)

There is still a vdev specific function, rte_cryptodev_create_vdev() in cryptodev.c.
That function should be deprecated, as virtual devices should be created through
EAL. A deprecation notice will be sent separately.

Pablo de Lara (12):
  cryptodev: store device pointer in virtual devices
  cryptodev: set driver name for all devices
  cryptodev: rename device retrieval argument
  cryptodev: simplify device list retrieval logic
  cryptodev: only set PCI info when device is PCI
  cryptodev: move vdev functions to a separate file
  cryptodev: release device if PCI device probing fails
  cryptodev: add PCI driver helpers
  crypto/qat: do not use cryptodev driver
  crypto/dpaa2_sec: do not use cryptodev driver
  cryptodev: remove unused PCI probe/remove
  cryptodev: remove unused cryptodev driver

[dpdk-dev] [PATCH 01/12] cryptodev: store device pointer in virtual devices

[Pablo de Lara]

Only non virtual devices were storing the pointer to
rte_device structure in rte_cryptodev, which will be needed
to retrieve the driver name for any device.

This is set in the rte_cryptodev_pmd_virtual_dev_init now so it isn't

Will fix in v2.

[dpdk-dev] [PATCH 02/12] cryptodev: set driver name for all devices

[Pablo de Lara]

When retrieving device information for a crypto driver,
driver name was only set when it was a PCI driver.
Getting the driver name from rte_device structure
allows rte_cryptodev_get_info() function to return it
regardless they are virtual or physical devices.

[dpdk-dev] [PATCH 03/12] cryptodev: rename device retrieval argument

[Pablo de Lara]

rte_cryptodev_devices_get() function was parsing a crypto
device name as an argument, but the function actually
returns device identifiers of devices that share the
same crypto driver, so the argument should be driver name, instead.

Fixes: 38227c0e3ad2 ("cryptodev: retrieve device info")

Yes, I forgot to change the variable name within the implementation.
I should better fix this and have it separated from the next one, though, 
because this patch should be backported, but the following patch changes
the implementation, which requires patch 2.

So, I will send a v2 with the fix for this patch.

[dpdk-dev] [PATCH 04/12] cryptodev: simplify device list retrieval logic

[Pablo de Lara]

rte_cryptodev_devices_get() function returns an array of devices
sharing the same driver.

Instead of having two different paths depending on the device being
virtual or physical, retrieve the driver name from rte_device structure.

As said, I will fix the previous one and leave this as it is.

[dpdk-dev] [PATCH 05/12] cryptodev: only set PCI info when device is PCI

[Pablo de Lara]

Do not set PCI information in the device information structure
for any crypto device, just for the ones that are PCI, so
this is set internally in the PCI crypto PMDs (only QAT now).

They are used in the PMDs, for crypto vdevs, so I can include the prefix that you suggest,
except for the last one (number_of_sockets). I think this one should be substituted by a better function,
implemented in EAL, and used in this and other places.
I will send a separate patchset to address this.

Will do this in v2.

[dpdk-dev] [PATCH 07/12] cryptodev: release device if PCI device probing fails

[Pablo de Lara]

Call rte_cryptodev_pmd_release_device() if probing a
PCI crypto device, instead of accessing the variables
directly. This will be useful when rte_cryptodev_pci_probe()
gets moved to a separate file.

[dpdk-dev] [PATCH 08/12] cryptodev: add PCI driver helpers

[Pablo de Lara]

Add PCI probe/remove/init/uninit functions in a separate
file rte_cryptodev_pci.h, which do not use cryptodev driver,
in order to be removed in next commits.

While most of the work seems to be done within this patchset, there are
still rte_pci.h includes in both:

lib/librte_cryptodev/rte_cryptodev.c:50:#include <rte_pci.h>
lib/librte_cryptodev/rte_cryptodev_pmd.h:50:#include <rte_pci.h>

This breaks the compilation when the PCI bus is compiled outside the EAL.
Would you be able to remove those last dependencies?

These includes have been removed already in the patchset.

Ah yes, sorry, I must have missed a few.
I have some trouble applying the patch however, I will test the
integration with the PCI bus move after I resolve this.

It might not apply cleanly after the latest patches that got merged.
I will send a rebased v2.

I am not sure which problem you are having. The patchset applies cleanly
on dpdk-next-crypto and dpdk.

[dpdk-dev] [PATCH v2 00/12] Remove cryptodev driver structure

[Pablo de Lara]

Following the same approach taken for ethdev, this patch series
removes the PCI specific structure cryptodev driver from rte_cryptodev.

The patchset makes the following changes:

- Moves the virtual and PCI device specific functions to separate files,
  so other cryptodev header files contain only device type agnostic
  functions.

- Modifies device info retrieval function to set the driver name for
  all devices and set PCI info inside PCI device PMDs

- Removes cryptodev driver structure from cryptodev library and drivers
  that were using it (QAT and DPAA2)

There is still a vdev specific function, rte_cryptodev_create_vdev()
in cryptodev.c. That function should be deprecated, as virtual devices
should be created through EAL.
A deprecation notice will be sent separately.

Changes in v2:

- Removed duplicated device setting

- Fixed compilation issue on a patch

- Added "rte_cryptodev_vdev" prefix in some functions

- Helper function (duplicated) has been removed, in
  the dependent patchset

This patch set depends on the following patches:
"[PATCH v2 0/4] Socket ID check removal"
(http://dpdk.org/ml/archives/dev/2017-June/068412.html)

Pablo de Lara (12):
  cryptodev: store device pointer in virtual devices
  cryptodev: set driver name for all devices
  cryptodev: rename device retrieval argument
  cryptodev: simplify device list retrieval logic
  cryptodev: only set PCI info when device is PCI
  cryptodev: move vdev functions to a separate file
  cryptodev: release device if PCI device probing fails
  cryptodev: add PCI driver helpers
  crypto/qat: do not use cryptodev driver
  crypto/dpaa2_sec: do not use cryptodev driver
  cryptodev: remove unused PCI probe/remove
  cryptodev: remove unused cryptodev driver

[dpdk-dev] [PATCH v2 01/12] cryptodev: store device pointer in virtual devices

[Pablo de Lara]

Only non virtual devices were storing the pointer to
rte_device structure in rte_cryptodev, which will be needed
to retrieve the driver name for any device.

[dpdk-dev] [PATCH v2 02/12] cryptodev: set driver name for all devices

[Pablo de Lara]

When retrieving device information for a crypto driver,
driver name was only set when it was a PCI driver.
Getting the driver name from rte_device structure
allows rte_cryptodev_get_info() function to return it
regardless they are virtual or physical devices.

[Pablo de Lara]

rte_cryptodev_devices_get() function was parsing a crypto
device name as an argument, but the function actually
returns device identifiers of devices that share the
same crypto driver, so the argument should be driver name, instead.

rte_cryptodev_devices_get() function returns an array of devices
sharing the same driver.

Instead of having two different paths depending on the device being
virtual or physical, retrieve the driver name from rte_device structure.

[dpdk-dev] [PATCH v2 05/12] cryptodev: only set PCI info when device is PCI

[Pablo de Lara]

Do not set PCI information in the device information structure
for any crypto device, just for the ones that are PCI, so
this is set internally in the PCI crypto PMDs (only QAT now).

[dpdk-dev] [PATCH v2 06/12] cryptodev: move vdev functions to a separate file

[Pablo de Lara]

Move all functions handling virtual devices to a separate
header file "rte_cryptodev_vdev.h", in order to leave only
generic functions for any device in the rest of the files.

This patch is moving some code from a .c to a .h.
The consequence is that driver are now compiling new functions
from the .h and require librte_kvargs to link with.
It is a build error in shared lib mode.

Please keep the code in a .c file if possible.

Sorry about this. I just fixed it in the subtree, so pull it whenever you are ready.
Also, since ethdev have separated pci and vdev functions in separate .h files,
I preferred to be consistent and do the same.

There is no reason to implement these functions in .h files.
I prefer to keep them in a .c file and just export the proto in .h.

This is same in the eth_dev too.

These are helper functions, and implementing them in .h file has the
benefit of function goes into PMD library, and there is no dependency
from PMDs to librte_ether for these functions (there are dependencies
for other functions ..).

It looks acceptable for me for helper functions to be implemented in
header file. But if we decide to move them into .c file, .map file
should be updated to export them, and I suppose ethdev also should be
updated to be compatible.

Thanks,
ferruh

Yes we should avoid adding code in .h.
It is accepted only for performance reasons.
ethdev can be reworked later.
cryptodev can be improved now and avoid adding rte_devargs deps on PMDs.

[dpdk-dev] [PATCH v2 07/12] cryptodev: release device if PCI device probing fails

[Pablo de Lara]

Call rte_cryptodev_pmd_release_device() if probing a
PCI crypto device, instead of accessing the variables
directly. This will be useful when rte_cryptodev_pci_probe()
gets moved to a separate file.

Re: [dpdk-dev] [PATCH v2 08/12] cryptodev: add PCI driver helpers

The build fails because of the brackets instead of quotes.
In a fresh build the cryptodev header is not available while
compiling cryptodev.
I am fixing it directly in master branch.
