| * drm/sysfs: fix hotplug regression since lifetime changesDavid Herrmann2013-11-211-7/+33
| | | | | | | | | | | | | | | | | | | | | | | | airlied: The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6 tried to use device_create, however that led to the regression where dev->type wasn't getting set correctly. First attempt at fixing it would have led to a race, so this undoes the device_createa work and does it all manually making sure the dev->type is setup before we register the device.

In the first occurence it was used to try to be nice while releasing the mmap_sem and retrying the fault to work around a locking inversion. The second occurence was never used. There has been some discussion whether we should change the locking order to mmap_sem -> bo_reserve. This patch doesn't address that issue, and leaves that locking order undefined. The solution that we release the mmap_sem if tryreserve fails and wait for the buffer to become unreserved is something we want in any case, and follows how the core vm system waits for pages to be come unlocked while releasing the mmap_sem. The code also outlines what needs to be changed if we want to establish the locking order as mmap_sem -> bo::reserve. One slight issue that remains with this code is that the fault handler might be prone to starvation if another thread countinously reserves the buffer. IMO that usage pattern is highly unlikely.

| | * drm/ttm: Don't move non-existing dataThomas Hellstrom2013-11-201-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ttm_bo_move_memcpy was instructed to move a non-populated ttm to io memory, it would first populate the ttm, then move the data and then destroy the ttm. That's stupid. However, some drivers might have relied on this to clear io memory from old stuff. So instead of a NOP, which would be the most efficient, just clear the destination.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lockdep warning is hit when evicting surfaces and reserving the backup buffer. Since this buffer can only be reserved by the process holding the surface reservation or by the buffer eviction processes that use tryreserve, there is no real deadlock here, but there's no other way to silence lockdep than to use a tryreserve. This means the reservation might fail if the buffer is about to be evicted or swapped out, but we now have code in place to handle that reasonably well.

That causes a "disabling already-disabled device" warning when removing a PCIe port device. This happens all the time when removing Thunderbolt devices, but is also easy to reproduce with, e.g., "echo 0000:00:1c.3 > /sys/bus/pci/drivers/pcieport/unbind" This patch removes the disable from pcie_portdrv_remove().
