Looks like we're only initializing dev_priv->atomic_cdclk_freq at resume and commit times, not at init time. Let's do that as well. We're now hitting the 'WARN_ON(intel_state->cdclk == 0)' in hsw_compute_linetime_wm() on account of populating intel_state->cdclk from dev_priv->atomic_cdclk_freq. Previously we were mispopulating intel_state->cdclk with dev_priv->cdclk_freq which always had a proper value at init time and hence the WARN_ON() didn't trigger.

Something I missed before sending off the partial series was that the non-scheduler guc reset path was broken (in the full series, this is pushed to the execlists reset handler). The issue is that after a reset, we have to refill the GuC workqueues, which we do by resubmitting the requests. However, if we already have submitted them, the fences within them have already been used and triggering them again is an error. Instead, just repopulate the guc workqueue.

In order to avoid some complexity in trying to reconstruct the workqueues across reset, remember them instead. The issue comes when we have to handle a reset between request allocation and submission, the request has reserved space in the wq, but is not in any list so we fail to restore the reserved space. By keeping the execbuf client intact across the reset, we also keep the reservations. Signed-off-by:

i915_guc_info() (part of debugfs output) tries to avoid holding struct_mutex for a long period by copying onto the stack. This causes a warning that the stack frame is massive, so stop doing that. We can even forgo holding the struct_mutex here as that doesn't serialise the values being read (and the lists used exist for the device lifetime). v2: Skip printing anything if guc->execbuf_client is disabled (avoids potential NULL dereference).

This patch adds support for DP MST audio in i915. Enable audio codec when DP MST is enabled if has_audio flag is set. Disable audio codec when DP MST is disabled if has_audio flag is set. Another separated patches to support DP MST audio will be implemented in audio driver. This patch is ported from commit 3708d5e0 ("drm/i915: start adding dp mst audio") And because commit 3708d5e0 ("drm/i915: start adding dp mst audio") breaks MST multi-monitor setups on some platforms, the orignal patch is reverted by commit be754b10 ("Revert "drm/i915: start adding dp mst audio"") As the multi-monitor setups issue is fixed, let's port the patch and enable the dp mst audio.

99% of the time we access i915_address_space->dev we want the i915 device and not the drm device, so let's store the drm_i915_private backpointer instead. The only real complication here are the inlines in i915_vma.h where drm_i915_private is not yet defined and so we have to choose an alternate path for our asserts. Signed-off-by:

a PT page will be released if it doesn't contain any meaningful mappings during PPGTT page table shrinking. The PT entry in the upper level will be set to a scratch entry. Normally this works nicely, but in virtualization world, the PPGTT page table is tracked by hypervisor. Releasing the PT page before modifying the upper level PT entry would cause extra efforts. As the tracked page has been returned to OS before losing track from hypervisor, it could be written in any pattern. Hypervisor has to recognize if a page is still being used as a PT page by validating these writing patterns. It's complicated. Better let the guest modify the PT entry in upper level PT first, then release the PT page. Reviewed-by:

David found another issue with priority bumping from mmioflips, where we are accessing the requests concurrently to them being retired and freed. Whilst we are skipping the dependency if has been submitted, that is not sufficient to stop the dependency from disappearing if another thread retires that request. To prevent we can either employ the struct_mutex (or a request mutex in the future) to serialise retiring before it is freed. Alternatively, we need to keep the dependencies alive using RCU whilst they are being accessed via the DFS.

The check in __intel_uncore_early_sanitize() to disable decoupled mmio would disable it for every platform that is not broxton. While that's not a problem now since only broxton supports that, simply setting .has_decoupled_mmio in a new platform's device info wouldn't suffice. So avoid future confusion and change the workaround to only change the value of has_decoupled_mmio for broxton. v2: git add compile fix.

Currently, we have an active reference for the request until it is retired. Though it cannot be retired before it has been executed by hardware, the request may be completed before we have finished processing the execute fence, i.e. we may continue to process that fence as we free the request.

Before we return the request back to the kmem_cache after a failed i915_gem_request_alloc(), we should assert that it has not been added to any global state tracking. Signed-off-by:

While we will check that the request is completed prior to being retired, by placing an assert that the request is complete at the entrypoint of the function we can more clearly document the function's preconditions. Signed-off-by:

Show the last submitted seqno to the engine, not the overall next seqno, as this is more pertinent information when inspecting the pageflip and whether the CS or display engine stalled. Signed-off-by:

Rename i915_gem_timeline member 'next_seqno' into 'seqno' as the variable is pre-increment. We've already had two bugs due to the confusing name, second is fixed as follow-up patch. Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

Some monitors will have noise or even no sound after applying the patch 6014ac12. In patch 6014ac12, it will reset the cts value to 0 for HDMI. However, we need to disable Enable CTS or M Prog bit. This is the initial setting after HW reset. Fixes: 6014ac12 ("drm/i915/audio: set proper N/M in modeset") Signed-off-by:

As i915.enable_cmd_parser is an unsafe option, make it read-only at runtime. Now that it is constant, we can use the value determined during initialisation as to whether we need the cmdparser at execbuffer time. v2: Remove the inline for its single user, it is clear enough (and shorter) without!

The i915_next_seqno read value is to be the next seqno used by the kernel. However, in the conversion to atomics ops for gt.next_seqno, in commit 28176ef4 ("drm/i915: Reserve space in the global seqno during request allocation"), this was changed from a post-increment to a pre-increment. This increment was missed from the value reported by debugfs, so in effect it was reporting the current seqno (last assigned), not the next seqno.

No sense in keeping the cmd_descriptor and cmd_table structs in i915_drv.h, now that they are no longer referenced externally. Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

Doing cmd_header >> 29 to extract our 3-bit client value where we know cmd_header is a u32 shouldn't then also require the use of a mask. So remove the redundant operation and get rid of INSTR_CLIENT_MASK now that there are no longer any users. Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

i915_hws_info() has not been kept upto date (missing new engines) and so I consider it to be unused. HWS is included in the error state, which would be an avenue to retrieving it if required in future (possibly via i915_engine_info). As it is currently oopsing with an rpm testcase, just remove it.

In all cases we can now obtain the relevant crtc_state/conn_state from the relevant callbacks, which means all the ->config accesses can be removed and the code cleaned up. Changes since v1: - cstate -> crtc_state Signed-off-by:

No need for the extra break statements and whatnot, just return the error directly. And tighten the scope of the local variables while at it. Signed-off-by:

A modeset on one pipe can update dev_priv->atomic_cdclk_freq without actually touching the hardware, in which case we won't force a modeset on all the pipes, and thus won't lock any of the other pipes either. That means a parallel plane update on another pipe could be looking at a stale dev_priv->atomic_cdcdlk_freq and thus fail to notice when the plane configuration is invalid, or potentially reject a valid update. To overcome this we must protect writes to atomic_cdclk_freq with all the crtc locks, and thus for reads any single crtc lock will be sufficient protection.
