What exact kernel API do you need? This patch set exposes the total number of keys and max keys, through sysfs. https://marc.info/?l=linux-kernel&m=150995950219669&w=2 Is this sufficient? or do you need something else?

[Linux-kselftest-mirror] [PATCH v2 0/2] selftests: firmware: skip testing unsupported features

by Amit Pundir

Hi, At Linaro we run mainline/linux-next selftests on LTS releases and run into few test failures due to kernel mismatch or missing upstream functionality in older kernels. Discussed at length here: https://lkml.org/lkml/2017/6/15/652 This patch series is an attempt to modify selftest firmware test scripts. The proposed changes skip/ignore testing the upstream functionality missing in the older kernel releases. v2: Changed the display message to make it consistent across all the firmware test scripts. Added Fixes tag.

[Linux-kselftest-mirror] [PATCH 0/2] selftests: firmware: skip testing unsupported features

by Amit Pundir

Hi, At Linaro we run mainline/linux-next selftests on LTS releases and run into few test failures due to kernel mismatch or missing upstream functionality in older kernels. Discussed at length here: https://lkml.org/lkml/2017/6/15/652 This patch series is an attempt to modify selftest firmware test scripts. The proposed changes skip/ignore testing the upstream functionality missing in the older kernel releases. Regards, Amit Pundir Amit Pundir (2): selftests: firmware: skip unsupported async loading tests selftests: firmware: skip unsupported custom firmware fallback tests tools/testing/selftests/firmware/fw_fallback.sh | 38 ++++++++++++++++------- tools/testing/selftests/firmware/fw_filesystem.sh | 34 ++++++++++++-------- 2 files changed, 47 insertions(+), 25 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I am not going reply to other patches you sent. Please make sure the patches are based on the latest release and tested on it as well. thanks, -- Shuah -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
