If we avoid cleaning up the old state immediately in intel_atomic_commit_tail() and defer it to a second task, we can avoid taking heavily contended locks when the caller is ready to procede. Subsequent modesets will wait for the cleanup operation (either directly via the ordered modeset wq or indirectly through the atomic helperr) which keeps the number of inflight cleanup tasks in check. As an example, during reset an immediate modeset is performed to disable the displays before the HW is reset, which must avoid struct_mutex to avoid recursion. Moving the cleanup to a separate task, defers acquiring the struct_mutex to after the GPU is running again, allowing it to complete. Even in a few patches time (optimist!) when we no longer require struct_mutex to unpin the framebuffers, it will still be good practice to minimise the number of contention points along reset. The mutex dependency still exists (as one modeset flushes the other), but in the short term it resolves the deadlock for simple reset cases.

In the guc_ctl_debug_flags, the ads struct is programmed only when USES_GUC_SUBMISSION is satisfied. But, this has to be programmed for all suspend/resume cases. Remove the condition and program the ads struct for both huc loading and guc submission. This issue was noticed when CI threw errors for enable_guc=2 (load huc; disable submission) v2: - Change commit title. - Correct the shifts.

Atm we're zeroing out fields in MG_PLL_BIAS and MG_PLL_TDC_COLDST_BIAS if refclk is 38.4MHz, whereas the spec tells us to preserve them. Although the calculated values mostly match the register defaults even for the 38.4MHz case, there are some differences wrt. what BIOS programs (I noticed at least differences in the MG_PLL_BIAS/IREFTRIM and MG_PLL_BIAS/BIASCAL_EN fields). In the lack of further info on how to program these fields, just do what the spec says and preserve the BIOS state. v2: - Preserve the BIOS programmed reg fields instead of programming them.

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).

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.
