If we use a non-forcewaked write to PMINTRMSK, it does not take effect until much later, if at all, causing a loss of RPS interrupts and no GPU reclocking, leaving the GPU running at the wrong frequency for long periods of time. Reported-by:

Since we depend upon RPS generating interrupts after evaluation intervals to determine when to up/down clock the GPU, it is imperative that we successfully enable interrupt generation! Verify that we do see an interrupt if we keep the GPU busy for an entire EI. Signed-off-by:

Even though the bspec is missing gen12 register details for the MCR selector register (0xFDC), this is confirmed by hardware folks to be a mistake; the register does exist and we do indeed need to steer multicast register reads to an appropriate instance the same as we did on gen11. Note that despite the lack of documentation we were still using the MCR selector to read INSTDONE and such in read_subslice_reg() too. Cc: Matt Atwood <matthew.s.atwood@intel.com> Signed-off-by:

We need to start passing memory latency as a parameter when calculating plane wm levels, as latency can get changed in different circumstances(for example with or without SAGV). So we need to be more flexible on that matter. v2: Changed latency type from u32 to unsigned int(Ville Syrjälä) Reviewed-by:

Replace the TGL/ICL specific platform checks with a more generic check using INTEL_GEN(). Fixes bug with broken audio after S3 resume on JSL platforms. An initial version of state save and restore of AUD_FREQ_CNTRL register was added for subset of platforms in commit 87c16945 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"). The state save has proven to work well and it is needed in newer platforms, so needs to be extended. Although the logic is not in practise needed on GEN9/10 systems, follow the hardware specification and apply state and restore on all gen9+ platforms.

After changing the timing between GTT updates and execution on the GPU, we started seeing sporadic failures on Ironlake. These were narrowed down to being an insufficiently strong enough barrier/delay after updating the GTT and scheduling execution on the GPU. By forcing the uncached read, and adding the missing barrier for the singular insert_page (relocation paths), the sporadic failures go away.

With timeslice yielding on a semaphore, we may complete timeslices much faster than we were expecting and already have yielded the stuck request. Before complaining that timeslicing is not enabled, check that we haven't already applied the switch. Signed-off-by:

Since the semaphore interrupt may cause us to yield the timeslice immediately, we may cancel the timer before we notice the submission is complete. The assertion is no longer valid due to the race with the interrupt. Signed-off-by:

If we find ourselves waiting on a MI_SEMAPHORE_WAIT, either within the user batch or in our own preamble, the engine raises a GT_WAIT_ON_SEMAPHORE interrupt. We can unmask that interrupt and so respond to a semaphore wait by yielding the timeslice, if we have another context to yield to! The only real complication is that the interrupt is only generated for the start of the semaphore wait, and is asynchronous to our process_csb() -- that is, we may not have registered the timeslice before we see the interrupt. To ensure we don't miss a potential semaphore blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark the interrupt and apply it to the next timeslice regardless of whether it was active at the time. v2: We use semaphores in preempt-to-busy, within the timeslicing implementation itself! Ergo, when we do insert a preemption due to an expired timeslice, the new context may start with the missed semaphore flagged by the retired context and be yielded, ad infinitum. To avoid this, read the context id at the time of the semaphore interrupt and only yield if that context is still active.

If we want to percolate information back from the HW, up through the GEM context, we need to wait until the intel_context is scheduled out for the last time. This is handled by the retirement of the intel_context's barrier, i.e. by listening to the pulse after the notional unpin. So wait until the intel_context is finally retired before releasing the engine, so that we can inspect the final context state and pass it on. Signed-off-by:

Allow the caller to also wait upon the barriers stored in i915_active. v2: Hook up i915_request_await_active(I915_ACTIVE_AWAIT_BARRIER) as well for completeness, and avoid the lazy GEM_BUG_ON()! v3: Pull flush_lazy_signals() under the active-ref protection as it too walks the rbtree and so we must be careful that we do not free it as we iterate.

Later use will require asynchronous waits on the active timelines, but will not utilize an async wait on the exclusive channel. Make the await on the exclusive fence explicit in the selection flags. Signed-off-by:

If we set the debug flag to force ourselves not to relocate via the gpu, do not relocate via the gpu. Signed-off-by:

__i915_gem_object_flush_map() takes a byte range, so feed it the written bytes and do not mistake the u32 index as bytes! Fixes: a679f58d ("drm/i915: Flush pages on acquisition") Signed-off-by:
