platform/x86: intel_atomisp2_led: Also turn off the always-on camera LED on the Asus T100TAF

2022-07-10T17:46:31+00:00

Like the Asus T100TA the Asus T100TAF has a camera LED which is always on by default and both also use the same GPIO for the LED. Relax the DMI match for the Asus T100TA so that it also matches the T100TAF. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20220710173658.221528-1-hdegoede@redhat.com

platform/x86/intel/ifs: Mark as BROKEN

2022-07-10T15:41:06+00:00

A recent suggested change to the IFS code has shown that the userspace API needs a bit more work, see: https://lore.kernel.org/platform-driver-x86/20220708151938.986530-1-jithu.joseph@intel.com/ Mark it as BROKEN before 5.19 ships, to give ourselves one more kernel-devel cycle to get the userspace API right.

platform/x86/intel: Fix pmt_crashlog array reference

2022-06-10T19:59:08+00:00

The probe function pmt_crashlog_probe() may incorrectly reference the 'priv->entry array' as it uses 'i' to reference the array instead of 'priv->num_entries' as it should. This is similar to the problem that was addressed in pmt_telemetry_probe via commit 2cdfa0c20d58 ("platform/x86/intel: Fix 'rmmod pmt_telemetry' panic"). Cc: "David E.

Documentation: In-Field Scan

2022-05-12T13:35:29+00:00

Add documentation for In-Field Scan (IFS). This documentation describes the basics of IFS, the loading IFS image, chunk authentication, running scan and how to check result via sysfs. The CORE_CAPABILITIES MSR enumerates whether IFS is supported. The full github location for distributing the IFS images is still being decided. So just a placeholder included for now in the documentation. Future CPUs will support more than one type of test. Plan for that now by using a "_0" suffix on the ABI directory names. Additional test types will use "_1", etc. Reviewed-by: Dan Williams Signed-off-by: Tony Luck Reviewed-by: Thomas Gleixner Link: https://lore.kernel.org/r/20220506225410.1652287-13-tony.luck@intel.com Signed-off-by: Hans de Goede
