2010-11-19drm/i915: Take advantage of auto-polling CRT hotplug detection on PCH hardwareKeith Packard
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.

2010-11-19drm/i915: Do not hold mutex when faulting in user addressesChris Wilson
Linus Torvalds found that it was rather trivial to trigger a system freeze: In fact, with lockdep, I don't even need to do the sysrq-d thing: it shows the bug as it happens. 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.

2010-11-18drm/ttm: Fix up a theoretical deadlockThomas Hellstrom
A process suspended waiting for a higher sequence or no sequence to unreserve, a bo may be beaten to the reservation by a process with a lower sequence. In that case the first process should give up trying to reserve and return -EAGAIN. In order for that to happen, we must wake waiting processes when we change sequence, so that they have a chance to detect the new sequence.
