[PATCH 1/4] net/dpaa2: stop using software annotation

[PATCH 1/4] net/dpaa2: stop using software annotation

[Hemant Agrawal]

The DPAA2 driver is not using the DPAA2 frame descriptor
software annotation area. This patch reduces the
PTA length to zero and adjust the RX Buffer Layout
accordingly.

Where this free operation done when it is removed from dpaa2_dev_uninit() ?

[PATCH 4/4] net/dpaa2: support parallel recv mode

[Hemant Agrawal]

Typically when the PMD issues a RX command to DPAA2 hardware,
the hw writes the available descriptors into the given memory.
The RX function then processes the frames and prepare them as
mbufs.

This patch adds support to issue another pull request to hardware
in another memory location, before we start processing the output
of the first request. This help in controlling the cpu cycles
wasted during the wait for the hardware to write the descriptors.

During hw debugging, it may be desired to keep the original
mode, so the original mode is also preserved and can be controlled
with an env flag.

Instead of getting configuration option from environment variable, can
you please make it argument to the driver?
This will be more consistent to the DPDK usage.

I guess you are talking about the devargs.  That code is still not 
cleaned up for non-pci devices.

In any case, we will work on that cleanup.

Can you please describe reasoning and effect in commit log:

What will happen when cortex-a72 used instead of cortex-a57+fp+simd? And
what is the motivation for change?

Thanks,

We will update the commit log for this and other patches as you commented.

W.r.t this patch, the revision of  LS2 devices now have cortex-a72, we 
have stopped A57.  fp and simd is no more required to be stated 
explicitly and supported by default in standard a72 core.

Same comment here, can you please mention in the commit log why this
piece of code removed, what will be effect of the removal.

Thanks,

[PATCH v2 03/20] net/dpaa2: stop using software annotation

[Hemant Agrawal]

The DPAA2 driver is not using the DPAA2 frame descriptor
software annotation area. This patch reduces the
PTA length to zero and adjust the RX Buffer Layout
accordingly.

[PATCH v2 05/20] bus/fslmc: support for parallel Rx DQ requests

[Hemant Agrawal]

DPAA2 hardware support the option to configure
multiple memories for Rx recv buffer (DPAA2-DQRR).
Each Rx request executing is called as 'DQ' request.
This patch adds routines to get information w.r.t each DQ request.

[PATCH v2 06/20] net/dpaa2: support parallel Rx mode

[Hemant Agrawal]

Typically when the PMD issues a RX command to DPAA2 hardware,
the hw writes the available descriptors into the given memory.
The RX function then processes the frames and prepare them as
mbufs.

This patch adds support to issue another pull request to hardware
in another memory location, before we start processing the output
of the first request. This help in controlling the cpu cycles
wasted during the wait for the hardware to write the descriptors.

Syntax should be:

DPDK_17.08 {
	global:

	qbman_result_SCN_state_in_mem;

} DPDK_17.05;

No "local: *", and previous group (DPDK_17.05) after "}".

But again, it would be nice if you can document in commit log, why
exporting this variable required now?

Thanks,

[PATCH v3 01/20] mk: change to cortex-a72

[Hemant Agrawal]

DPAA2 devices now support cortex-a72. They no longer support a57.
Also,  fp and simd is no more required to be stated explicitly for
standard a72 core.

[PATCH v3 05/20] bus/fslmc: support for parallel Rx DQ requests

[Hemant Agrawal]

DPAA2 hardware support the option to configure
multiple memories for Rx recv buffer (DPAA2-DQRR).
Each Rx request executing is called as 'DQ' request.
This patch adds routines to get information w.r.t each DQ request.

[PATCH v3 06/20] net/dpaa2: support parallel Rx in eth pmd

[Hemant Agrawal]

Typically when the PMD issues a RX command to DPAA2 hardware,
the hw writes the available descriptors into the given memory.
The RX function then processes the frames and prepare them as
mbufs.

This patch adds support to issue another pull request to hardware
in another memory location, before we start processing the output
of the first request. This help in controlling the cpu cycles
wasted during the wait for the hardware to write the descriptors.

Also,  fp and simd is no more required to be stated explicitly for
standard a72 core.

[PATCH v4 03/20] net/dpaa2: stop using software annotation

[Hemant Agrawal]

The DPAA2 driver is not using the DPAA2 frame descriptor
software annotation area. This patch reduces the
PTA length to zero and adjust the RX Buffer Layout
accordingly.

[PATCH v4 05/20] bus/fslmc: support for parallel Rx DQ requests

[Hemant Agrawal]

DPAA2 hardware support the option to configure
multiple memories for Rx recv buffer (DPAA2-DQRR).
Each Rx request executing is called as 'DQ' request.
This patch adds routines to get information w.r.t each DQ request.

[PATCH v4 06/20] net/dpaa2: support parallel Rx in eth pmd

[Hemant Agrawal]

Typically when the PMD issues a RX command to DPAA2 hardware,
the hw writes the available descriptors into the given memory.
The RX function then processes the frames and prepare them as
mbufs.

This patch adds support to issue another pull request to hardware
in another memory location, before we start processing the output
of the first request. This help in controlling the cpu cycles
wasted during the wait for the hardware to write the descriptors.

There are new files in this patch, whose file headers don't explicitly
say "BSD LICENSE" or mention from dual licensing as some other files do.

I already get the patchset to next-net, can you please send only
incremental patch to update file headers and I can squash it to existing
patchset?

Thanks,
ferruh
