| | | | | | | | | | | | | | | | | | | | | | Move the access control up from the fast paths, which are no longer universally taken first, up into the caller. This then duplicates some sanity checking along the slow paths, but is much simpler. Tracked as CVE-2010-2962.

| * drm/i915: Use pipe state to tell when pipe is offKeith Packard2010-10-032-25/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of waiting for the display line value to settle, we can simply wait for the pipe configuration register 'state' bit to turn off. Contrarywise, disabling the plane will not cause the display line value to stop changing, so instead we wait for the vblank interrupt bit to get set. And, we only do this when we're not about to wait for the pipe to turn off. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

| | | | | | | | | | | | | | | | | | | | | | While the display port is in training mode, vblank interrupts don't occur. Because we have to wait for the display port output to turn on before starting the training sequence, enable the output in 'normal' mode so that we can tell when a vblank has occurred, then start the training sequence.

| * | drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie2010-10-0110-29/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were lots of places being inconsistent since handle count looked like a kref but it really wasn't. Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.

| * drm/radeon/kms: only warn on mipmap size checks in r600 cs checker (v2)Alex Deucher2010-09-151-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The texture base address registers are in units of 256 bytes. The original CS checker treated these offsets as bytes, so the original check was wrong. I fixed the units in a patch during the 2.6.36 cycle, but this ended up breaking some existing userspace (probably due to a bug in either userspace texture allocation or the drm texture mipmap checker). So for now, until we come up with a better fix, just warn if the mipmap size it too large. This will keep existing userspace working and it should be just as safe as before when we were checking the wrong units. These are GPU MC addresses, so if they fall outside of the VRAM or GART apertures, they end up at the GPU default page, so this should be safe from a security perspective. v2: Just disable the warning. It just spams the log and there's nothing the user can do about it.

| * drm: fix race between driver loading and userspace open.Dave Airlie2010-09-142-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Not 100% sure this is due to BKL removal, its most likely a combination of that + userspace timing changes in udev/plymouth. The drm adds the sysfs device before the driver has completed internal loading, this causes udev to make the node and plymouth to open it before we've completed loading. The proper solution is to delay the sysfs manipulation until later in loading however this causes knock on issues with sysfs connector nodes, so we can use the global mutex to serialise loading and userspace opens.

| * drm/radeon/kms: increase lockup detection interval to 10 sec for r100-r500Marek Olšák2010-09-131-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One subtest of mesa/demos/gltestperf takes 9 seconds to complete, so to prevent an unnecessary gpu reset followed by a hardlock, I am increasing the interval to 10 seconds after which a GPU is considered in a locked-up state. This is on RV530. However, with a little slower GPU, we would surpass the interval easily, so this is not a good fix for gltestperf. Nevertheless, this commit also fixes hardlocks in the applications which render at speed of less than 1 frame per second, where the whole frame consists of only one command stream. The game Tiny & Big is an example. This bar is now lowered to 0.1 fps. Now the question comes down to whether we should (often unsuccessfully) reset the GPU at all? Once we have stable enough drivers, we won't have to. Has the time come already? If possible, this commit should go to stable as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I broke out my trusty i845 and found a new boot failure, which upon inspection turned out to be a recursion within: drm_helper_probe_single_connector_modes() -> drm_helper_hpd_irq_event() -> intel_crt_detect() -> drm_helper_probe_single_connector_modes() Calling drm_kms_helper_poll_enable() instead performs the desired re-initialisation of the polling should the user have toggled the parameter, without the recursive side-effect.

* | drm/i915: Hold a reference to the object whilst unbinding the eviction listChris Wilson2010-09-201-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During heavy aperture thrashing we may be forced to wait upon several active objects during eviction. The active list may be the last reference to these objects and so the action of waiting upon one of them may cause another to be freed (and itself unbound). To prevent the object disappearing underneath us, we need to acquire and hold a reference whilst unbinding. This should fix the reported page refcount OOPS: kernel BUG at drivers/gpu/drm/i915/i915_gem.c:1444! ...

| | | | | | | | | | | | | | | | | | | | | | With 5 places to update when adding handling for fence registers, it is easy to overlook one or two. Correct that oversight, but fence management should be improved before a new set of registers is added.
