Creating and opening the GuC log relay file enables and starts the relay potentially before the caller is ready to consume logs. Change the behavior so that relay starts only on an explicit call to the write function (with a value of '1'). Other values flush the log relay as before. v2: Style changes and fix typos. Add guc_log_relay_stop() function.

Atm we don't detect a PCH with PCI ID 0xA3C1 which showed up now on a CML platform. We don't have the official assignment of the PCH PCI IDs, but this looks like a CNP which was already used on CML platforms. Let's add the new ID->PCH type mapping accordingly.

DSC isn't DP specific, so remove the dp_ prefix from the crtc state member name. Also moving the member under the dsc sub-struct gives us enough context to allow shortening the name to just config. No functional changes. Cc: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by:

If retirement is running on another thread, we may inspect the status of the i915_active before its retirement callback is complete. As we expect it to be running synchronously, we can wait for any callback to complete by acquiring the i915_active.mutex. Signed-off-by:

The actual conditions are that we know the GPU is not accessing the context, and we hold a pin on the context image to allow CPU access. We used a fake lock on ce->pin_mutex so that we could try and use lockdep to assert that access is serialised, but the various different hardirq/softirq contexts where we need to *fake* holding the pin_mutex are causing more trouble. Still it would be nice if we did have a way to reassure ourselves that the direct update to the context image is serialised with GPU execution. In the meantime, stop lockdep complaining about false irq inversions. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111923Signed-off-by:

Loop over all engines, issuing a request for the object on each in order to make sure we leave no stone unturned when creating an active ref. The purpose is to make sure that we can reap a zombie object (one that is only alive due to an active reference on the GPU) no matter where that active reference emanates from. Signed-off-by:

With the last user, i915_vma_parked(), retired, there are no more users of the per-gt pm notifications and we can remove the unused infrastructure. Signed-off-by:

Chris Wilson authored
Currently even though i915_vma_parked() operates on a per-gt struct, it is called from a global pm notify. This oddity was only because the long term plan is to decouple the vma cache from the pm notification, but right now the oddity stands out like a sore thumb! Suggested-by:

To flush idle barriers, and even inflight requests, we want to send a preemptive 'pulse' along an engine. We use a no-op request along the pinned kernel_context at high priority so that it should run or else kick off the stuck requests. We can use this to ensure idle barriers are immediately flushed, as part of a context cancellation mechanism, or as part of a heartbeat mechanism to detect and reset a stuck GPU. Signed-off-by:

On ILK+ the documented min hdisplay is 64, min hblank is 32, and min vblank is 5. On earlier platforms min hblank is also 32, and min vblank is 3. Make sure the mode satisfies those limits. There are further limits for HDMI and pfit use cases, but we'll check for those in a more specific location. Signed-off-by:

If we change the priority of the active context, then it has no impact on the decision of whether to preempt the active context -- we don't preempt the context with itself. In this situation, we elide the tasklet rescheduling and should *not* be marking up the queue_priority_hint as that may mask a later submission where we decide we don't have to kick the tasklet as a higher priority submission is pending (spoiler alert, it was not).
