(Ideally we should have a custom sphinx class for it)

Please rework and do not commit such .txt file, thanks

[dpdk-dev] [PATCH v3 1/3] doc: add skeleton for eventdevs feature matrices

[Sunil Kumar Kori]

Patch adds skeleton for feature matrices for event dev
and Rx/Tx adapters.

Along with, .ini files are added for all supported PMDs.

Signed-off-by: Sunil Kumar Kori <skori@marvell.com>

v3:
 - Removed .txt files to generate tables.
 - Use conf.py script to generate tables.
 - Add .ini file for all supported PMDs.
v2:
 - Review comments incorporated

+  Tree maintainers and eventdev adapter maintainers

1) Please rebase to dpdk-next-eventdev
2) Please update devtools/check-doc-vs-code.sh
You can use search _CAP_ and != CAP_REQUIRES_ to detect the capability
change or so.
3) Update the .ini for all the eventdev drivers, not just Marvell ones.

I hope this OK. I understand that without this it gives errors and
feature-length is not enough

1) Please sync the doc order with flag definition order in header file[1]
2) You can remove RTE_EVENT_DEV_CAP_REQUIRES_MAINT from the
list(*CAP_REQUIRES*) as this
is limitation.

Please make this as [Eth Rx adapter Features]

You can remove Eth Rx/Tx adapter as new subject has [Eth Rx adapter]

I don't think this is OK, because it would enlarge the size of all tables.
Please confirm (especially for NICs table).
Is there a way to make the feature names smaller?

Maybe we should negate RTE_EVENT_DEV_CAP_REQUIRES_MAINT to make it fit 
better with the other capabilities? To be more in line with how the API 
has been adapted to cope with various eventdev hardware limitations 
(e.g., RTE_EVENT_DEV_CAP_CARRY_FLOW_ID).

RTE_EVENT_DEV_CAP_MAINTENANCE_FREE

All event devices/drivers would set this except DSW.

If this make sense and it's not too late to tweak the API, I can create 
a patch.

Makes sense. Just add those cap in !dsw drivers.
Please send it now, I will merge it soon.

[dpdk-dev] [PATCH] eventdev: negate maintenance capability flag

[Mattias Rönnblom]

Replace RTE_EVENT_DEV_CAP_REQUIRES_MAINT, which signaled the need
for the application to call rte_event_maintain(), with
RTE_EVENT_DEV_CAP_MAINTENANCE_FREE, which does the opposite (i.e.,
signifies that the event device does not require maintenance).

This approach is more in line with how other eventdev hardware and/or
software limitations are handled in the Eventdev API.

Generally patch looks fine to me, but on testing I got a strange warning from the
compiler on the OPDL driver:

                 from ../drivers/event/opdl/opdl_evdev.c:15:

Investigating, RTE_EVENT_DEV_CAP_* are assigned to struct rte_event_dev_info::event_dev_cap,
which is a uint32_t. The error suggests that the variable being assigned to is a "unsigned char"?

Aha! Replace:

with:

The "," character was causing the _FREE flag to not be combined with the previous
flags field, instead being its own (unnamed?) assignment to the struct rte_event_dev_info.

With that , to | change, all looks good to me. -Harry

[dpdk-dev] [PATCH v2] eventdev: fix Rx adapter stalls on event device backpressure

[Mattias Rönnblom]

In the Eventdev Ethernet RX Adapter, correctly handle the case where
the circular enqueue buffer head and last index point to the same
element.

This bug may be triggered in case there is backpressure from the event
device to the RX adapter.

* Corrected bug description

[dpdk-dev] [PATCH v3] eventdev: negate maintenance capability flag

[Mattias Rönnblom]

Replace RTE_EVENT_DEV_CAP_REQUIRES_MAINT, which signaled the need
for the application to call rte_event_maintain(), with
RTE_EVENT_DEV_CAP_MAINTENANCE_FREE, which does the opposite (i.e.,
signifies that the event device does not require maintenance).

This approach is more in line with how other eventdev hardware and/or
software limitations are handled in the Eventdev API.

v3: Fix invalid references in the API documentation
v2: New flag was not properly set in opdl_evdev.c

[PATCH v6 01/11] doc: add skeleton for eventdevs feature matrices

[skori]

From: Sunil Kumar Kori <skori@marvell.com>

Patch adds skeleton for feature matrices for event dev
and Rx/Tx adapters.

Along with, .ini files are added for all supported PMDs.

Signed-off-by: Sunil Kumar Kori <skori@marvell.com>
---
v6:
 - Rebased to 21.11 rc2
 - Added feature matrices for all supported drivers
 - Added doc vs code check script
 
v5:
 - Rebased to 21.11
 - Added feature matrix for cnxk.
v4:
 - Rebased to 20.02
v3:
 - Removed .txt files to generate tables.
 - Use conf.py script to generate tables.
 - Add .ini file for all supported PMDs.
v2:
 - Review comments incorporated

v6:
 - Rebased to 21.11 rc2
 - Added feature matrices for all supported drivers
 - Added doc vs code check script
 
v5:
 - Rebased to 21.11
 - Added feature matrix for cnxk.
v4:
 - Rebased to 20.02
v3:
 - Removed .txt files to generate tables.
 - Use conf.py script to generate tables.
 - Add .ini file for all supported PMDs.
v2:
 - Review comments incorporated

doc/guides/eventdevs/features/cnxk.ini
based on driver file. Please converge cn9k.ini and cn10k.ini as cnxk.ini

Following errors[2] need to be taken care in
devtools/parse-event-support.sh by detecting it is using a common Rx
adapter or not?
I have spent some time fixing it, Please find below a test patch for same[1].
Please send the next version with fix. I am planning to merge all doc
patches(1-10) to next-event-dev tree and delegate this
patch(11/11) to Thomas as he is the maintainer for tooling.

[PATCH v8 01/10] doc: add skeleton for eventdevs feature matrices

[skori]

From: Sunil Kumar Kori <skori@marvell.com>

Patch adds skeleton for feature matrices for event dev
and Rx/Tx adapters.

Along with, .ini files are added for all supported PMDs.

Signed-off-by: Sunil Kumar Kori <skori@marvell.com>

v8:
 - Fix script dump for dsw and SW driver
 - Review comments incorporated
v7:
 - Rebased to 21.11 rc3
 - Fix Tx adapter capabilities for SW driver
v6:
 - Rebased to 21.11 rc2
 - Added feature matrices for all supported drivers
 - Added doc vs code check script
 
v5:
 - Rebased to 21.11
 - Added feature matrix for cnxk.
v4:
 - Rebased to 20.02
v3:
 - Removed .txt files to generate tables.
 - Use conf.py script to generate tables.
 - Add .ini file for all supported PMDs.
v2:
 - Review comments incorporated

I think a v9 is needed.
I am sending other comments.
Note: it can all be in one single patch.

These 2 functions are mostly copy/paste of rte_flow functions.
Given there will be more in future, I would prefer code being factorized.

Can it be a single query?

No need to check all drivers.
For rte_flow, only changed drivers are checked.

Why echo?

Why so many quotes?

Why having extra parameter, instead of updating the pattern?
By the way, the pattern RTE_EVENT_ETH_RX_ADAPTER_CAP_ already include all of this.

I think these functions can be factorized.

RE: [EXT] Re: [PATCH v8 10/10] devtools: check event device doc tables

[Sunil Kumar Kori]

Hi Thomas,

It will take some time to handle all the comments for this patch. So I would request you to defer this patch for next release and take other patches in series. 
Also I will send one patch to add feature matrix for dlb2 platform and fix minor review comments given by You.

This is just documentation, so it can be merged
until the last day of the release.
Please try to get the script ready.
If the script is not ready on time, I will merge only the doc.

[PATCH v1 1/1] doc: update eventdev feature matrix for dlb2

[skori]

From: Sunil Kumar Kori <skori@marvell.com>

Patch updates eventdev and adapters feature matrices for
dlb2 driver.

RE: [EXT] Re: [PATCH v8 01/10] doc: add skeleton for eventdevs feature matrices

[Sunil Kumar Kori]

Hi Thomas,

Just wanted to confirm that all documentation patches should go as single patch or I can send it as a series of patches. 
I am ready with dlb2 changes also. Once you confirm I will send patches accordingly. Please confirm.


Regards
Sunil Kumar Kori

There is no specific comment in each patch, so it can go all in a single patch (v9).
