| | | | | | | | | | | sil164 and friends are the most common, usually they just need to be poked once because a fixed configuration is enough for any modes and clocks, so they worked without this patch if the BIOS had done a good job on POST. Display couldn't survive a suspend/resume cycle though. Unfortunately, BIOS scripts are useless here.

* drm/nouveau: Fix AGP reset when AGP FW is already enabled on init.Francisco Jerez2010-08-05
| | | | | | | | | | | Previously nouveau_mem_reset_agp() was only disabling AGP fast writes when coming back from suspend. However, the "locked out of the card because of FW" problem can also be reproduced on init if you unload/reload nouveau.ko several times. This patch makes the AGP code reset FW on init.

The primary reason for this change is because debug logs are rather hard to read with the hundreds of single-byte auxch transactions that occur. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm: kill BKL from common codeArnd Bergmann2010-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | This restricts the use of the big kernel lock to the i830 and i810 device drivers. The three remaining users in common code (open, ioctl and release) get converted to a new mutex, the drm_global_mutex, making the locking stricter than the big kernel lock. This may have a performance impact, but only in those cases that currently don't use DRM_UNLOCKED flag in the ioctl list and would benefit from that anyway. The reason why i810 and i830 cannot use drm_global_mutex in their mmap functions is a lock-order inversion problem between the current use of the BKL and mmap_sem in these drivers. Since the BKL has release-on-sleep semantics, it's harmless but it would cause trouble if we replace the BKL with a mutex. Instead, these drivers get their own ioctl wrappers that take the BKL around every ioctl call and then set their own handlers as DRM_UNLOCKED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some BIOSes will claim a large chunk of stolen space. Unless we reclaim it, our aperture for remapping buffer objects will be constrained. So clamp the stolen space to 32M and ignore the rest. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15469 among others. Adding the ignored stolen memory back into the general pool using the memory hotplug code is left as an exercise for the reader.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The docs warn that to position the cursor such that no part of it is visible on the pipe is an undefined operation. Avoid such circumstances upon changing the mode, or at any other time, by unsetting the cursor if it moves out of bounds.

| * drm/i915: Unreference object not handle on creationChris Wilson2010-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating an object, we create the handle by which it is known to the process and which own the reference to the object. That reference to the new handle is what we want to transfer to the process, not the lost reference to the object; so free the local object reference *not* the process's handle reference.

| | | | | | | | | | | | | | | | | | | | | | | | | | If we fail to flush outstanding GPU writes but return the memory to the system, we risk corrupting memory should the GPU recovery and complete those writes. On the other hand, if we bail early and free the object then we have a definite use-after-free and real memory corruption. Choose the lesser of two evils, since in order to recover from the hung GPU we need to completely reset it, those pending writes should never happen.

| * drm/i915: Repeat unbinding during free if interrupted (v6)Chris Wilson2010-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If during the freeing of an object the unbind is interrupted by a system call, which is quite possible if we have outstanding GPU writes that must be flushed, the unbind is silently aborted. This still leaves the AGP region and backing pages allocated, and perhaps more importantly, the object remains upon the various lists exposing us to memory corruption. I think this is the cause behind the use-after-free, such as Bug 15664 - Graphics hang and kernel backtrace when starting Azureus with Compiz enabled https://bugzilla.kernel.org/show_bug.cgi?id=15664 v2: Daniel Vetter reminded me that kernel space programming is never easy. We cannot simply spin to clear the pending signal and so must deferred the freeing of the object until later. v3: Run from the top level retire requests. v4: Tested with P(return -ERESTARTSYS)=.5 from i915_gem_do_wait_request() v5: Rebase against Eric's for-linus tree. v6: Refactor, split and add a comment about avoiding unbounded recursion.
