[dpdk-dev] [PATCH 01/22] net/bnxt: fix to handle error case during port start

[Ajit Khaparde]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

1. during port start, if bnxt_init_chip() return error
   bnxt_dev_start_op() invokes bnxt_shutdown_nic() which in turn calls
   bnxt_free_all_hwrm_resources() to free up resources. Hence remove the
   bnxt_free_all_hwrm_resources() from bnxt_init_chip() failure path.
2. fix to check the return value of rte_intr_enable() as this call
   can fail.
3. set bp->dev_stopped to 0 only when port start succeeds.
4. handle failure cases in bnxt_init_chip() routine to do proper
   cleanup and return correct error value.

[dpdk-dev] [PATCH 05/22] net/bnxt: fix setting primary MAC address

[Ajit Khaparde]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

1. Default filter is tied to VNIC 0 at index 0. After finding the filter
   with mac_index 0 and set the new MAC address, looping through
   remaining filters is unnecessary.
2. Added a check for NULL MAC address.
3. bnxt_hwrm_set_l2_filter() clears the existing filter configuration
   first before applying new filter settings. Hence there is no need to
   invoke bnxt_hwrm_clear_l2_filter() explicitly in
   bnxt_set_default_mac_addr_op().

   no need to do individual function cleanups in failure path.
2. rearrange the check for primary process to remove an unwanted goto.
3. fix to invoke bnxt_hwrm_func_buf_unrgtr() in bnxt_dev_uninit() when
   it is needed.

[dpdk-dev] [PATCH 07/22] net/bnxt: reset filters before registering interrupts

[Ajit Khaparde]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

If interrupt registration fails during device init, driver invokes
uninit which in turn causes error messages while trying to free
vnic filters. Fix this by moving filter initialization call before
interrupt registration.

[dpdk-dev] [PATCH 09/22] net/bnxt: use dedicated cpr for async events

[Ajit Khaparde]

From: Lance Richardson <lance.richardson@broadcom.com>

This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.

For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring. This behavior
is controlled by a compile-time configuration variable.

For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).

Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.

Normally we don't want to introduce new config time options as much as possible.

This is what happens when patches slip in the last minute, please Ajit try to
send patches before proposal next time.

And back to the config option, is it something have to be a compile time flag
(if so why?), can it be replaced by a devarg?

I confirm it is nack.
I don't see any reason not to replace it with a runtime devargs.

This build-time configuration option was introduced because the
"shared async completion
ring" configuration is needed for one specific platform,
arm64-stingray-linux-gcc. This
configuration has a number of drawbacks and should be avoided
otherwise. Making it
a run-time option will add complexity and introduce the possibility
that existing stingray
users will not know that they need to specify this option as of 19.08,
so it would be good
if some other way could be found to handle this.

Other than perhaps using RTE_ARCH_ARM64 to select the shared completion ring
configuration (which would obviously affect all ARM64 users), are
there any other options
that might be acceptable?

It's maybe worthwhile to note that the last several DPDK releases use
the "shared completion
ring" configuration.

Thanks and regards,

   Lance

I see this provides a configuration transparent to user, but won't this kill the
binary portability? If a distro packages an 'armv8a' target and distributes it,
this won't be usable in your 'stingray' platform for the driver.

But if this is added as a devargs, it can be usable even with distributed
binaries, by providing proper devargs to binary for a specific platform. And
documenting this devargs in NIC guide can help users to figure it out.

I dropped this patch from next-net since discussion is going on, I did my best
to resolve the conflicts but please confirm the final result in next-net.

Can you detect the platform in the PMD?

Re: [dpdk-dev] [PATCH 09/22] net/bnxt: use dedicated cpr for async events

[Lance Richardson]

Yes, the platform can be detected at runtime
from the PCI device ID. This would be a better
approach than adding a configuration parameter,
I think. I'll take a look.

Thanks,

I did some basic testing of the current head of dpdk-next-net and diffed
against the original version, everything looks OK.

I will follow up with another patch that has the build-time configuration stuff
removed.

[dpdk-dev] [PATCH] net/bnxt: use dedicated cpr for async events

[Lance Richardson]

This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.

For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring. This behavior
is controlled by a compile-time configuration variable.

For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).

Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.

I will follow up with a v2 to correct the above statement in the commit log and
to squash with these follow-up patches:

[dpdk-dev] [[PATCH v2]] net/bnxt: use dedicated cpr for async events

[Lance Richardson]

This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.

For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring.

For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).

Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.

Allow rxq 0 to be stopped when not being used for async events.

[dpdk-dev] [PATCH 10/22] net/bnxt: retry irq callback deregistration

[Ajit Khaparde]

From: Lance Richardson <lance.richardson@broadcom.com>

rte_intr_callback_unregister() can fail if the handler happens to
be active at the time of the call. Add logic to retry a reasonable
number of times to help ensure that the callback is unregistered
on uninit.

[Ajit Khaparde]

From: Lance Richardson <lance.richardson@broadcom.com>

BCM57500-based adapters use a variable number of RSS contexts
depending upon the number of receive rings in use. The current
implementation is erroneously using the maximum possible number
of RSS contexts instead of the actual number allocated when
setting up RSS tables in the adapter. Fix by using the actual
number of allocated contexts.

From: Lance Richardson <lance.richardson@broadcom.com>

The current implementation erroneously passes the address of the

address of the appropriate subtable for the context. This results
in only the first 64 receive queues being used. Fix by passing the
correct address for each context.

[dpdk-dev] [PATCH 20/22] net/bnxt: fix MAC/VLAN filter allocation failure

[Ajit Khaparde]

From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>

We were adding the VLAN filters to all the VNICs of the function.
Also, we were adding these VLANs to all the existing MAC only filters.
This was resulting in fewer VLANs getting added. By default we should
allocate MAC+VLAN filter only to the default VNIC of the function using
the default mac address.
Similar logic was followed in the VLAN deletion code. This patch fixes it.
Use inner VLAN fields instead of outer VLAN during filter deletion to be
in sync with VLAN addition code.

Fixes: 246c5cc5f0 ("net/bnxt: use correct flags during VLAN configuration")

Hi Ajit,

All bnxt patches has been sent after rc1, and this one has been sent a day
before rc2. A believe you are aware that proposal deadline was "June 3, 2019".

I will still try to get them but most probably the patchset won't able to make
this release, fyi.

Regards,
ferruh

I understand. But most of these including the next patch set are bug fixes.
It just that some stayed in our staging area longer. But most of them
were detected and fixed in the last week when our QA ramped testing on
rc1.

Intact as I type this mail I see two more bug fixes ready for submission.
