The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

During system suspend, the "wait for ring buffer to empty" loop would always time out after three seconds, because the faster cached ring buffer head read would always return zero. Force the slow-and-careful PIO read on all but the first iterations of the loop to fix it. This also removes the unused (and useless) 'actual_head' variable that tried to approximate doing this, but did it incorrectly. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rafael J.

First, we were calling mc_stop() at the top of the function which turns off all MC (memory controller) clients, then checking if the GPU is idle. If it was idle we returned without re-enabling the MC clients which would lead to a blank screen, etc. This patch checks if the GPU is idle before calling mc_stop(). Second, if the reset failed, we were returning without re-enabling the MC clients. This patch re-enables the MC clients before returning regardless of whether the reset was successful or not.

Hopefully, this is a temporary measure whilst the root cause is understood. At the moment, we experience a hard hang whilst looping urbanterror that has been identified as a result of the use of semaphores, but so far only on SNB mobile.

After reordering the sequence of relocating objects, commit 6fe4f140, we can no longer rely on seeing all reloc targets prior to performing the relocation. As a result we were ignoring the need to flush objects from the render cache and invalidate the sampler caches, resulting in rendering glitches. So we need to clear the relocation domains earlier.

On the fault path, commit 6fe4f140 introduction a regression whereby it changed the sequence of the objects but continued to use the original ordering of relocation entries. The result was that incorrect GTT offsets were being fed into the execbuffer causing lots of misrendering and potential hangs.

Whilst we had no older batches on the active list, everything was fine. However, if the GPU is free running and the requests are only being reaped by the periodic retirer, than the current seqno may not be at the start of the list. In this case we need to select the first batch after the last seqno written by the gpu and not inclusive of the seqno. Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk>

As the mappable portion of the aperture is always a small subset at the start of the GTT, it is allocated preferentially by drm_mm. This is useful in case we ever need to map an object later. However, if you have a large object that can consume the entire mappable region of the GTT this prevents the batchbuffer from fitting and so causing an error. Instead allocate all those that require a mapping up front in order to improve the likelihood of finding sufficient space to bind them. Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk>

Rather than evicting an object at random, which is unlikely to alleviate the memory pressure sufficient to allow us to continue, zap the entire aperture. That should give the system long enough to recover and reap some pages from the evicted objects, forestalling the allocation error for the new object.

In order to retire active buffers whilst no client is active, we need to insert our own flush requests onto the ring. This is useful for servers that queue up some rendering and then go to sleep as it allows us to the complete processing of those requests, potentially making that memory available again much earlier.

Dave Airlie spotted that his ILK laptop with DMAR enabled was generating the occasional DMAR warning.
