** Description changed: - This is for tracking purpose. + BugLink: https://bugs.launchpad.net/bugs/2070158 + + [Impact] + This is a feature request from HP, RFIM is for frequency, SAGV is for voltage. + They are used as dynamic switching to reduce RF noise. RFIM is already + supported in the kernel, this patchset adds the SAGV feature. + + [Fix] + Cherry-pick 6 commits from mainline kernel + + [Test] + Enable the SAGV from the BIOS, booting with the patched kernel, after booting + up, run 'systemctl status dtt.service', we will get: service is enabled and + service is running + run 'cat /sys/kernel/debug/dri/0000:00:02.0/i915_sagv_status', we will get: + SAGV available: Yes + SAGV status: enabled + + [Where problems could occur] + Because the fix is for i915, it is likely introduce regression on graphic, + but this possibility is very low. These 6 commits are merged to + mainline kernel from v6.10-rc1, so far there is no regression reported + on them. And we tested the patched kernel on different Intel machines, all + worked well.
