The seqno value actually written out to memory is no longer in the

Previously this was a single patch, but as the changes grew from v1 to

We should be checking if drm_dp_dpcd_read() returns the size that we are
asking it to read instead of just checking if it is greater than zero.
So, compare the return value of drm_dp_dpcd_read() to the requested
read size.

Don't enable it for the cursor plane, because its .atomic_update callback

Stolen memory is not usable for MTL A0 stepping beyond
certain access size and we have no control over userspace
access size of /dev/fb which can be backed by stolen memory.
So disable stolen memory backed fb by setting i915->dsm.usable_size
to zero.

Hi.
Is it likely that this fix will be sumbmitted to mainline during the ongoing
6.3 development cycle?

Write-combining memory allows speculative reads by CPU.
ggtt->error_capture is WC mapped to CPU, so CPU/MMU can try
to prefetch memory beyond the error_capture, ie it tries
to read memory pointed by next PTE in GGTT.
If this PTE points to invalid address DMAR errors will occur.
This behaviour was o
The callback will be responsible for setting scratch page PTEs for
specified range. In contrast to clear_range it cannot be optimized to nop.
It will be used by code adding guard pages.

This patch tries to diminish plague of DMAR read errors present
in CI for ADL*, RPL*, DG2 platforms, see for example [1] (grep DMAR).
CI is usually tolerant for these errors, so the scale of the problem
is not really visible.
To show it I have counted lines containing DMAR read errors in dmesgs
