That's good to know, thx. But the more important things are: * When will those be merged? They are not yet in next yet afaics, so it might take some time to mainline them, especially at this point of the devel cycle. Imre, could you try to prod the right people so that these are ideally upstreamed rather sooner than later, as they fix a regression? * They if possible ideally should be tagged for backporting to 6.4, as this is a regression from the 6.3 cycle. But yes, let's tell regzbot that fixes are available, too: #regzbot fix: drm/i915: Fix HPD polling, reenabling the output poll work as needed (for the record: that's the second of two patches apparently needed) Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. >> BTW, there was an earlier report about a problem with a4e771729a51 that >> afaics was never addressed, but it might be unrelated. >> https://lore.kernel.org/all/20230328023129.3596968-1-zhouzongmin@kylinos.cn/ > [1] https://patchwork.freedesktop.org/patch/548590/?series=121050&rev=1 > [2] https://patchwork.freedesktop.org/patch/548591/?series=121050&rev=1
