2011-01-26console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2-9/+9
The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

2011-01-24drm/i915: Use consistent mappings for OpRegion between ACPI and i915Michael Karcher1-1/+2
The opregion is a shared memory region between ACPI and the graphics driver. As the ACPI mapping has been changed to cachable in commit 6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion non-cachable now fails. As no bus-master hardware is involved in the opregion, cachable map should do no harm. Tested on a Fujitsu Lifebook P8010.

2011-01-23drm/i915: Recognise non-VGA display devicesChris Wilson3-4/+10
Starting with SandyBridge (though possible with earlier hacked BIOSes), the BIOS may initialise the IGFX as secondary to a discrete GPU. Prior, it would simply disable the integrated GPU. So we adjust our PCI class mask to match any DISPLAY_CLASS device. In such a configuration, the IGFX is not a primary VGA controller and so should not take part in VGA arbitration, and the error return from vga_client_register() is expected.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes4-5/+5
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.

2011-01-20i915: Fix i915 suspend delayLinus Torvalds2-3/+3
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.

2011-01-20drm/i915/ringbuffer: Fix use of stale HEAD position whilst polling for spaceChris Wilson2-17/+24
During suspend, Linus found that his machine would hang for 3 seconds, and identified that intel_ring_buffer_wait() was the culprit: "Because from looking at the code, I get the notion that "intel_read_status_page()" may not be exact. But what happens if that inexact value matches our cached ring->actual_head, so we never even try to read the exact case? Does it _stay_ inexact for arbitrarily long times? If so, we might wait for the ring to empty forever (well, until the timeout - the behavior I see), even though the ring really _is_ empty." As the reported HEAD position is only updated every time it crosses a 64k boundary, whilst draining the ring it is indeed likely to remain one value. If that value matches the last known HEAD position, we never read the true value from the register and so trigger a timeout.

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.

This reverts commit dfe63bb0ad9810db13aab0058caba97866e0a681. This commit was causing nouveau not to work properly, for -rc1 I'd prefer it worked and we can look if this is useful for 2.6.39.

2011-01-14drm/i915: Disable GPU semaphores on SandyBridge mobileChris Wilson1-1/+2
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.

2011-01-13drm/i915/execbuffer: Clear domains before beginning reloc processingChris Wilson1-4/+3
After reordering the sequence of relocating objects, commit 6fe4f1404, 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.

2011-01-13drm/i915/execbuffer: Reorder relocations to match new object orderChris Wilson1-6/+9
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.

2011-01-13drm/i915: Fix error handler to capture the first batch after the seqnoChris Wilson1-1/+1
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: Chris Wilson <chris@chris-wilson.co.uk>

2011-01-11drm/i915/execbuffer: Reorder binding of objects to favour restrictionsChris Wilson2-26/+47
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: Chris Wilson <chris@chris-wilson.co.uk>
