Subject: [PATCH] drm/dp: Change AUX DPCD probe address from DPCD_REV to
LANE0_1_STATUS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Reading DPCD registers has side-effects in general. In particular
accessing registers outside of the link training register range
(0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly
forbidden by the DP v2.1 Standard, see
3.6.5.1 DPTX AUX Transaction Handling Mandates
3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates
Based on my tests, accessing the DPCD_REV register during the link
training of an UHBR TBT DP tunnel sink leads to link training failures.
Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the
DPCD register access quirk.

Hi Sasha, Greg and stable team,
please don't backport this patch and drop it from the queues for the
5.4, 5.10, 5.15, 6.1, 6.6, 6.12, 6.16 stable trees. It causes an issue
which is described at
https://lore.kernel.org/stable/aGaiASySvb3BVXlM@ideak-desk
I initially asked not to apply the patch to stable trees - and then it
was dropped as I requested - but as I understand now it still got
selected/queued automatically. Sorry for the trouble it caused, let me
know if there's a better way to avoid auto selecting such patches for
stable in the future (for one I can CC Sasha on such requests).
Thanks,
Imre
