description |
[Impact]
Set screen off on ThinkPad P1G5 with 4k+ panel.
The screen will never be back.
[Fix]
It's a upstream kernel regression.
And reverted by upstream.
[Test]
Verified on hardware, screen on/off 20 times OK.
[Where problems could occur]
Low risk, it reverts a regression and may break i915 driver.
On 5.14-oem and Jammy kernel, This commit was claimed to backport
commit 73867c8709b5 ("drm/i915/display: Remove check for low voltage sku for max dp source rate")
But it's not kind of it.
So revert it instead.
On 5.17 kernel, revert it by upstream commit.
Unstable kernel already got it. |
