[PATCH 00/15] net/ena: driver release 2.10.0

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

Hi all,
This release contains:
1. HAL upgrade to latest divided into separate patches.
2. three bug fixes.
3. restructuring of the Rx checksum code for readability
4. restructuring of the device uninit flow which is also needed
   for adding hot un/plug support later.
5. modification of logs on the datapath that leads to improved performance.

Will appreciate your feedbacks!
All the best and thanks in advance,
Shai

[PATCH 01/15] net/ena/base: add descriptor dump capability

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

This patch adds the capability to print rx/tx descriptors.
This patch introduces a new function ena_com_tx_cdesc_idx_to_ptr
which is the equivalent of ena_com_rx_cdesc_idx_to_ptr but for tx cdesc.

Finally, this patch moves the io_cq header incrementation in
ena_com_cdesc_rx_pkt_get() function to be after the possible if fail
cases since it makes more sense to point into the next descriptor only
if the last one is valid.

[PATCH 03/15] net/ena/base: remove redundant assert checks

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

Remove ENA_WARN checks from ena_com_wait_and_process_admin_cq_polling
since once the execution flow reaches the check, it must be
ENA_CMD_COMPLETED because it can't be either of the other options:
1. ENA_CMD_ABORTED - in such case it will perform "goto err" in the "if"
   block above, thus skipping the ENA_WARN check.
2. ENA_CMD_SUBMITTED - in such case it will timeout inside the while(1)
   loop above and perform "goto err", thus skipping the ENA_WARN check.

Remove ENA_WARN check from ena_com_wait_and_process_admin_cq_interrupts
since once the execution flow reaches the check, it must be
ENA_CMD_COMPLETED because it can't be either of the other options:
1. ENA_CMD_ABORTED - same as above, i will perform "goto err" in the
   "if" block above, thus skipping the ENA_WARN check.
2. ENA_CMD_SUBMITTED - in such case it will perform "goto err" in the
   nested if block above, since "admin_queue->polling" is false (because
   of the interrupt mode execution of admin commands)

This commit adds the support for a new reset reason
for `MISS_FIRST_INTERRUPT` in order to distinguish

Hi Shai,

I don't know about implication of dropping the copyright year
altogether, we need to ask to an expert.

What I know is, a copyright expires after some year, so to hold the
copyright, there needs to be a starting point. And people use ranges to
extend this copyright year.


Instead of removing the year altogether, it make sense to me to just
keep the initial year and don't add range later as code updated, this
also will be more consistent with rest of the code.
Let me drop this patch from the set, and learn more from the experts. It
can be included later, I don't think this is something urgent.


Another aspect is, the history of a source file can be acquired from the
pubic git repository, so when it is first merged, when updated, all
these information is available.
So this feels like no need to record these days in the source code files
but I don't know if these git repository metadata information is legally
 valid and accepted.


And I am not quite sure if it has really any value to worry about
copyright for a publicly available device driver code anyway, but this
is not my domain.

Hi Shai,

     Will you please just update the copyright year instead of removing 
the year completely?  e.g. 2015-2020, 2024 or 2015-2024

[Brandes, Shai] 
Hi Ferruh and Hemant, aws removed the copyrights' years range completely for all our open source drivers based on our legal team and the open source article that states that there is no need to provide years or ranges of years for copyright notices in an OSS project. 
https://www.linuxfoundation.org/blog/blog/copyright-notices-in-open-source-software-projects
leaving this patch out or using a different years range will create code difference between the dpdk driver and the HAL code it consumes, which is common to all ENA drivers (which is less maintainable.)
Thanks,
Shai

Hi Shai,

I made the comment to make sure you are protected, but if this is the
request coming from your legal team I think you already know what you
are doing and I am OK to continue with the patch.

By the way, thanks for the blog, it can be reference for future discussions.

[PATCH 09/15] net/ena: logger change to improve performance

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

Current implementation of ena_trc_dbg on every TX packet has a major
performance impact on DPDK TX flow.
Profiling revealed that these calls, which trigger rte_log usage,
consume a significant amount of CPU resources.

Change details:
1. Several warning prints that incorrectly used ena_trc_dbg will now be
   compiled out. They have been changed to ena_trc_warn to avoid
   compiler warnings, such as empty if/else body or unused parameter.
2. Removed variables which is used only inside prints and thus
   may be unreferenced.
3. calls for ena_trc_dbg will be enabled only if
   RTE_ETHDEV_DEBUG_TX or RTE_ETHDEV_DEBUG_RX defined

[PATCH 10/15] net/ena: rework device uninit

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

Rework device uninitialization flow to ensure complete resource
cleanup, and lay the groundwork for hot-unplug support. With this
change, `ena_destroy_device()` is removed, its functionality now
incorporated into `ena_close()`.

[PATCH 11/15] net/ena: fix bad checksum handling

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

Removed a workaround for a false L4 bad Rx csum
indication from the device. The workaround was to set it
as unknown so the application would check it instead.
The issue was fixed in the device, thus the driver bad csum
handling should be fixed in the PMD.

[PATCH 13/15] net/ena: fix wrong handling of checksum

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

This change fixes an issue where a non tcp/udp packet can be indicated
to have an invalid csum. If the device erroneously tries to verify the
csum on a non tcp/udp packet it will result in false indication that
there is a csum error. This change make the driver ignore the
indication for csum error on such packets.

[shaibran]

From: Shai Brandes <shaibran@amazon.com>

This restructure is a simplification of the
Rx checksum inspection logic in ena_rx_mbuf_prepare.
Its purpose is to improve readability and maintainability
by consolidating conditions.
