g4x+ sprites have an extra cdclk limitation listed for RGB formats. For some random reason I chose to use cpp>=4 as the check for that. While that does actually work let's deobfuscate it by checking for !is_yuv instead. I suspect is_yuv didn't exist way back when I originally write the code. Also drop the duplicate comment.

Even if we're not doing downscaling we should account for some of the extra dotclock limitations for g4x+ sprites. In particular we must never exceed the 90% rule, and with RGB that limits actually drops to 80%. So instead of bailing out when upscaling let's clamp the scaling factor appropriately and go through the rest of calculation normally. By luck we already did the full calculations for the 1:1 case.

The CACHE_MODE_0 save/restore was added without explanation in commit 1f84e550 ("drm/i915 more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)"). If there are any bits we care about those should be set explicitly during some appropriate init function. Let's assume it's all good and just nuke this magic save/restore. Signed-off-by:

Originally added in commit 1f84e550 ("drm/i915 more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)") to fix some underruns. I suspect that was due to the trickle feed settings getting clobbered during suspend. We've been disabling trickle feed explicitly since commit 20f94967 ("drm/i915: Disable trickle feed via MI_ARB_STATE for the gen4") so this magic save/restore should no longer be needed.

The FBC_CONTROL save restore is there just to preserve the compression interval setting. Since commit a68ce21b ("drm/i915/fbc: Store the fbc1 compression interval in the params") we've been explicitly setting the interval to a specific value, so the sace/restore is now entirely pointless.

There's no real reason to stash away the DPIO PHY IOSF sideband port numbers for VLV/CHV. Just compute them at runtime in the sideband code. Gets rid of the oddball intel_init_dpio() function from the high level init flow. Signed-off-by:

Logically part of the display restore. Note: This has been in place since the introduction of gmbus support. The gmbus code also does the resets before transfers. Is this really needed, or a historical accident? Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Disable all display feature flags when there are no pipes i.e. there is no display. This should help with not having to additionally check for HAS_DISPLAY() when a feature flag check would suffice.

This function should be an int, not a bool. Presumably because we had the same 2 reverts in a slightly different way, git got confused. Thanks to Dan for reporting. :) The conflict is between the 3 reverts in drm-fixes: 4993a8a3 ("Revert "drm/i915: Remove i915_gem_object_get_dirty_page()"") ad5d95e4 ("Revert "drm/i915/gem: Async GPU relocations only"") 20561da3 ("Revert "drm/i915/gem: Delete unused code"") And the slightly different combined revert in drm-intel-gt-next, but with the same goal: 102a0a90 ("Revert "drm/i915/gem: Async GPU relocations only"") In the merge commit 1f4b2aca ("Merge tag 'drm-intel-gt-next-2020-09-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next") things went wrong, but the merge commit view now doesn't show any conflict anymore (as git tends to do when the resolution picks one or the other branch). The need to handle other than just true/false error codes in __reloc_entry_gpu was added in the dma_resv locking changes in c43ce123 ("drm/i915: Use per object locking in execbuf, v12.")

The hwsp_gtt object is used for sub-allocation and could therefore be shared by many contexts causing unnecessary contention during concurrent context pinning. However since we're currently locking it only for pinning, it remains resident until we unpin it, and therefore it's safe to drop the lock early, allowing for concurrent thread access. Signed-off-by:

(NOTE: This is the minimal backportable fix, a full fix is being developed at https://patchwork.freedesktop.org/patch/388048/) The flags passed to the wait_entry.func are passed onwards to try_to_wake_up(), which has a very particular interpretation for its wake_flags. In particular, beyond the published WF_SYNC, it has a few internal flags as well. Since we passed the fence->error down the chain via the flags argument, these ended up in the default_wake_function confusing the kernel/sched.

To implement preempt-to-busy (and so efficient timeslicing and best utilization of the hardware submission ports) we let the GPU run asynchronously in respect to the ELSP submission queue. This created challenges in keeping and accessing the driver state mirroring the asynchronous GPU execution. Previous fix 1d9221e9 ("drm/i915: Skip signaling a signaled request") however did not correctly serialize request retirement with the execution callbacks. We were using the i915_request.lock to serialise adding an execution callback with __i915_request_submit. However, if we use an atomic llist_add to serialise multiple waiters and then check to see if the request is already executing, we can remove the irq-spinlock and fix serialization between retirement and execution callbacks in one go. v2: Avoid using the irq_work when outside of the irq-spinlocks, where we can execute the callbacks immediately. v3: Pay close attention to the order of setting ACTIVE on retirement, we need to ensure the request is signaled and breadcrumbs detached before we finish removing the request from the engine. v4: Expanded commit message.
