Add support for LZ4 compression algorithm for both API and app.
In addition, enable app to test de/comp only. This option already
exists in both app doc and arguments but isn't implemented inside the
application.
LZ4: https://github.com/lz4/lz4
RFC: https://patchwork.dpdk.org/project/dpdk/patch/20220410182622.8828-1-rzidane@nvidia.com/
Depends-on: patch-26344 ("compressdev: fix end of comp PMD list macro conflict")
Michael Baum (4):
compressdev: add LZ4 algorithm support
app/test-compress-perf: allow test single compress operation
app/test-compress-perf: add algo option
app/test-compress-perf: add LZ4 support

Add support for LZ4 algorithm:
- Add Lz4 param structure to XFORM structures.
- Add capabilities flags for LZ4 params.
- Add xxHash-32 checksum and capabilities flag.

Part of the application options is to test only compress and only
decompress but actually the application ignores this user option and
tries to test always both compress and decompress.
Allow testing only compress and only decompress.

To: dev; +Cc: Matan Azrad, Akhil Goyal, Ashish Gupta, Fiona Trahe, Thomas Monjalon
Add a command line option `algo` to select the compress algorithm
supported by the compress API: null (DMA), deflate and lzs.
Default for deflate.

Why did you start with 4th and 5th bit of the flags? Why not first two bits?

I didn't choose the values by myself, I took them from LZ4 standard:

Ok, Are we defining and making the frame descriptor inside library?
Also, why all the bits not added?
I believe these are just flags which PMD would use to make the frame descriptors.
If so, we should start with 0th bit and let the PMD handle bit shifting.

Add support for LZ4 compression algorithm for both API and app.
In addition, enable app to test de/comp only. This option already
exists in both app doc and arguments but isn't implemented inside the
application.
LZ4: https://github.com/lz4/lz4
RFC:
https://patchwork.dpdk.org/project/dpdk/patch/20220410182622.8828-1-rzidane@nvidia.com/
v2:
- Add macros for all LZ4 flags in the standard.
- Rebase.
Depends-on: series-26738 ("compressdev: fix end of list enums conflict")

compressdev: add LZ4 algorithm support

Add support for LZ4 algorithm:
- Add Lz4 param structure to XFORM structures.
- Add capabilities flags for LZ4 params.
- Add xxHash-32 checksum and capabilities flag.

Part of the application options is to test only compress and only
decompress but actually the application ignores this user option and
tries to test always both compress and decompress.
Allow testing only compress and only decompress.

Add a command line option `algo` to select the compress algorithm
supported by the compress API: null (DMA), deflate and lzs.
Default for deflate.

Add support for LZ4 compression algorithm for both API and app.
In addition, enable app to test de/comp only. This option already
exists in both app doc and arguments but isn't implemented inside the
application.
LZ4: https://github.com/lz4/lz4
RFC:
https://patchwork.dpdk.org/project/dpdk/patch/20220410182622.8828-1-rzidane@nvidia.com/
v2:
- Add macros for all LZ4 flags in the standard.
- Rebase.
v3:
- Rebase.
Michael Baum (4):

- Add Lz4 param structure to XFORM structures.
- Add capabilities flags for LZ4 params.
- Add xxHash-32 checksum and capabilities flag.

To: dev; +Cc: Matan Azrad, Akhil Goyal, Ashish Gupta, Fiona Trahe, Thomas Monjalon
Part of the application options is to test only compress and only
decompress but actually the application ignores this user option and
tries to test always both compress and decompress.
Allow testing only compress and only decompress.

Add a command line option `algo` to select the compress algorithm
supported by the compress API: null (DMA), deflate and lzs.
Default for deflate.

From the description it seems to be a bug in previous implementation.
Can we back port it? And update the patch title accordingly?
Also, release note update is not required for this fix.

Since LZ4 is also supported now, is it not good to add that also in this patch?

This change is not related to this patch.

Hi,
The patchset only have library change and added performance tests.
We shall have at least one PMD to support the added algorithms and unit
test updated for the PMD/algorithms.

Fan

There is another patchset which adds it in MLX5 compress PMD:
series-26766 ("compress/mlx5: add LZ4 support") https://patchwork.dpdk.org/project/dpdk/cover/20230202162537.1067595-1-michaelba@nvidia.com/

Add support for LZ4 compression algorithm for both API and app.
In addition, enable app to test de/comp only. This option already
exists in both app doc and arguments but isn't implemented inside the
application.
LZ4: https://github.com/lz4/lz4
RFC:
https://patchwork.dpdk.org/project/dpdk/patch/20220410182622.8828-1-rzidane@nvidia.com/
v2:
- Add macros for all LZ4 flags in the standard.
- Rebase.
v3:
- Rebase.
v4:
- Change "allow test single" commit to fix and add "Cc: stable@dpdk.org".
- Take all typo fixes into separate commit.
- Squash "add LZ4 algo" commit into "add algo option" commit.
- Remove unnecessary release notes updates.

Add support for LZ4 algorithm:
- Add Lz4 param structure to XFORM structures.
- Add capabilities flags for LZ4 params.
- Add xxHash-32 checksum and capabilities flag.

Part of the application options is to test only compress and only
decompress but actually the application ignores this user option and
tries to test always both compress and decompress.
Allow testing only compress and only decompress.

From: Michael Baum @ 2023-02-14 17:40 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Akhil Goyal, Ashish Gupta, Fiona Trahe, Thomas Monjalon
Add a command line option `algo` to select the compress algorithm
supported by the compress API: null (DMA), deflate, lz4 and lzs.
Default for deflate.
