selftests: firmware: Add ZSTD compressed file tests

2022-04-22T06:51:17Z

It's similar like XZ compressed files. For the simplicity, both XZ and ZSTD tests are done in a single function. The format is specified via $COMPRESS_FORMAT and the compression function is pre-defined.

selftests: firmware: Simplify test patterns

2022-04-22T06:51:17Z

The test patterns are almost same in three sequential tests. Make the unified helper function for improving the readability.

selftests: firmware: Fix the request_firmware_into_buf() test for XZ format

2022-04-22T06:51:17Z

The test uses a different firmware name, and we forgot to adapt for the XZ compressed file tests. https://lore.kernel.org/all/20210127154939.13288-1-tiwai@suse.de/ Fixes: 1798045900b7 ("selftests: firmware: Add request_firmware_into_buf tests") Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20220421152908.4718-4-tiwai@suse.de Signed-off-by: Greg Kroah-Hartman

selftests: firmware: Use smaller dictionary for XZ compression

2022-04-22T06:51:16Z

The xz -9 option leads to an unnecessarily too large dictionary that isn't really suitable for the kernel firmware loader. Pass the dictionary size explicitly, instead. While we're at it, make the xz command call defined in $RUN_XZ for simplicity.

test_firmware: Test partial read support

2020-10-05T11:37:04Z

Add additional hooks to test_firmware to pass in support for partial file read using request_firmware_into_buf(): buf_size: size of buffer to request firmware into partial: indicates that a partial file request is being made file_offset: to indicate offset into file to request Also update firmware selftests to use the new partial read test API.

selftests: firmware: Add compressed firmware tests

2019-06-18T07:11:22Z

This patch adds the test cases for checking compressed firmware load. Two more cases are added to fw_filesystem.sh: - Both a plain file and an xz file are present, and load the former - Only an xz file is present, and load without '.xz' suffix The tests are enabled only when CONFIG_FW_LOADER_COMPRESS is enabled and xz program is installed.

Revert "selftests: firmware: remove use of non-standard diff -Z option"

2019-02-08T12:00:43Z

This reverts commit f70b472e937bb659a7b7a14e64f07308e230888c. This breaks testing on Debian, and this patch was NACKed anyway. The proper way to address this is a quirk for busybox as that is where the issue is present.

selftests: firmware: remove use of non-standard diff -Z option

2018-11-27T21:19:46Z

"diff -Z" is used to trim the trailing whitespace when comparing the loaded firmware file with the source firmware file. However, per the comment in the source code, -Z should not be necessary. In testing, the input and output files are identical. Additionally, -Z is not a standard option and is not available in environments such as busybox. When -Z is not supported, diff fails with a usage error, which is suppressed, but then causes read_firmwares() to exit with a false failure message.
