We only need to apply the BIAS for self-relocations into the batchbuffer iff the execobject has any relocations. This suppresses some warnings we may get with a full gtt (so the batch object has wound up at 0 from a previous invocation), but doesn't fix the underlying problem of how we tried to move a pinned batch vma (how we have a pinned user vma outside of execbuf, I do not know, though this being on an aliasing ppgtt means it could be a spurious pinning via the global gtt). One step at a time... References: https://bugs.freedesktop.org/show_bug.cgi?id=106744#c1 Testcase: igt/gem_exec_gttfill # byt (sporadic) Signed-off-by:

commit 5422b37c ("drm/i915/psr: Kill delays when activating psr back.") removed the call to cancel a scheduled psr_work from psr_disable() and instead added an early return in the work function. But, if the scheduled work item is executed after psr_enable(), we end up printing warnings as PSR is already enabled and active. So, put the cancel_work call back in psr_disable().

The PCH transcoder registers are only 12 bits wide for the hdisplay and hblank_start values. On HSW/BDW the CPU side registers are 13 bits wide. intel_mode_valid() only checks against the higher limit (since we don't know where the mode is to be used), so an extra check is required against the FDI limits.

Validate that all display timings fit within the number of bits we have in the transcoder timing registers. The limits are: hsw+: 4k: vdisplay, vblank_start 8k: everything else gen3+: 4k: h/vdisplay, h/vblank_start 8k: everything else gen2: 2k: h/vdisplay, h/vblank_start 4k: everything else Also document the fact that the mode_config.max_width/height limits refer to just the max framebuffer dimensions we support.

Because OCD. Now seriously, commit 1aa920ea ("drm/i915: add register macro definition style guide") has finally established a coding standard to be followed by the rest of the file, and I've been trying to request everybody to adhere to that since then. The problem is that when someone adds a new line to a register that has the wrong style, these people generally propagate the wrong style and I have to keep asking them to drive-by fix the whole register, which is not something I like to do and also creates extra work for them. Or I can ignore the propagation of the wrong coding style and feel anxious about it. On top of that, we now have our CI happily reminding us about these problems, which makes everything worse. So IMHO the best way to proceed is to fix the spacing issues in the file once and for all. Contributors will stop propagating the bad style when adding new bits to registers that already have bad style, we will stop asking them to redo their patches and the CI emails will become more relevant by having less semi-false errors. Yes, there will be some pain involved for backporters, but at least spacing issues like that are easy to spot and fix in the patch files. This patch was generated by: ../../../../scripts/checkpatch.pl -f --strict --types SPACING \ --fix-inplace i915_reg.h I manually checked the output and everything seems sane. v2: Single conflict around the addition of DP_TP_CTL_LINK_TRAIN_PAT4.

Having the w/a registers as an open-coded table leaves a trap for the unwary; it would be easy to miss incrementing the LRI counter when adding a new register to the list. Instead, pull the list of registers into a table, so that we only need add new registers to that table rather than try and remember important side-effects of earlier chunks of GPU instructions.

commit b2209e62 ("drm/i915/execlists: Reset the CSB head tracking on reset/sanitization") and commit 1288786b ("drm/i915: Move GEM sanitize from resume_early to resume") show the conflicting requirements on the code. We must reset the GPU before trashing live state on a fast resume (hibernation debug, or error paths), but we must only reset our state tracking iff the GPU is reset (or power cycled). This is tricky if we are disabling GPU reset to simulate broken hardware; we reset our state tracking but the GPU is left intact and recovers from its stale state. v2: Again without the assertion for forcewake, no longer required since commit b3ee09a4 ("drm/i915/ringbuffer: Fix context restore upon reset") as the contexts are reset from the CS ensuring everything is powered up.

The SF and clipper units mishandle the provoking vertex in some cases, which can cause misrendering with shaders that use flat shaded inputs. There are chicken bits in 3D_CHICKEN3 (for SF) and FF_SLICE_CHICKEN (for the clipper) that work around the issue. These registers are unfortunately not part of the logical context (even the power context), and so we must reload them every time we start executing in a context.
