| * drm/i915: Disable FBC on Ironlake to save 1WAlex Shi2010-11-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | Frame buffer compression is broken on Ironlake due to buggy hardware. Currently it is disabled through chicken bits, but it still consumes over 1W more than if we simply never attempt to enable the FBC code paths.

| * drm/i915: Take advantage of auto-polling CRT hotplug detection on PCH hardwareKeith Packard2010-11-191-38/+57
| | | | | | | | | | | | | | | | | | | | | | | | Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

It's the X server taking the same lock recursively. Here's the problem: ============================================= [ INFO: possible recursive locking detected ] 2.6.37-rc2-00012-gbdbd01a #7 --------------------------------------------- Xorg/2816 is trying to acquire lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e but task is already holding lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a other info that might help us debug this: 2 locks held by Xorg/2816: #0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a #1: (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b This recursion was introduced by rearranging the locking to avoid the double locking on the fast path (4f27b5d and fbd5a26d) and the introduction of the prefault to encourage the fast paths (b5e4f2b). In order to undo the problem, we rearrange the code to perform the access validation upfront, attempt to prefault and then fight for control of the mutex. the best case scenario where the mutex is uncontended the prefaulting is not wasted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tiled buffers have the same alignment requirements regardless of whether the surface is for db, cb, or textures.

| * | drm/i915: Retire any pending operations on the old scanout when switchingChris Wilson2010-11-133-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An old and oft reported bug, is that of the GPU hanging on a MI_WAIT_FOR_EVENT following a mode switch. The cause is that the GPU is waiting on a scanline counter on an inactive pipe, and so waits for a very long time until eventually the user reboots his machine. We can prevent this either by moving the WAIT into the kernel and thereby incurring considerable cost on every swapbuffers, or by waiting for the GPU to retire the last batch that accesses the framebuffer before installing a new one. As mode switches are much rarer than swap buffers, this looks like an easy choice.

| * | | drm/radeon/kms/atom: set sane defaults in atombios_get_encoder_mode()Alex Deucher2010-11-181-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there was no connector mapped to the encoder, atombios_get_encoder_mode() returned 0 which is the id for DP. Return something sane instead based on the encoder id. This avoids hitting the DP paths on non-DP encoders.
