2008-03-30Initialize the fence::error member.Thomas Hellstrom
2008-03-30[i915] Report buffer state _after_ fence submission to user-space.Thomas Hellstrom
This fixes a problem where the wrong bo->fence_type was reported, and also saves some memory space. [bo core] export the drm_bo_fill_rep_arg function.

Fix that got left out after the intel-post-reloc merge.

2008-03-17drm: pick correct master for cleaning upDave Airlie
When a master is exiting, make sure we clean it up and not the currently in charge master.
2008-03-17drm: select the correct master to attempt to remove the lock from.Dave Airlie
When destroying DRI sarea, make sure you use the master associated with the sarea and not the one currently in charge
2008-03-17drm/pcigart: fix the pci gart to use the drm_pci wrapper.Dave Airlie
This is the correct fix for the RS690 and hopefully the dma coherent work. For now we limit everybody to a 32-bit DMA mask but it is possible for RS690 to use a 40-bit DMA mask for the GART table itself, and the PCIE cards can use 40-bits for the table entries.

2008-03-14drm: Fix race that can lockup the kernelMike Isely
The i915_vblank_swap() function schedules an automatic buffer swap upon receipt of the vertical sync interrupt. Such an operation is lengthy so it can't be allowed to happen in normal interrupt context, thus the DRM implements this by scheduling the work in a kernel softirq-scheduled tasklet. In order for the buffer swap to work safely, the DRM's central lock must be taken, via a call to drm_lock_take() located in drivers/char/drm/drm_irq.c within the function drm_locked_tasklet_func(). The lock-taking logic uses a non-interrupt-blocking spinlock to implement the manipulations needed to take the lock. This semantic would be safe if all attempts to use the spinlock only happen from process context. However this buffer swap happens from softirq context which is really a form of interrupt context. Thus we have an unsafe situation, in that drm_locked_tasklet_func() can block on a spinlock already taken by a thread in process context which will never get scheduled again because of the blocked softirq tasklet. This wedges the kernel hard. To trigger this bug, run a dual-head cloned mode configuration which uses the i915 drm, then execute an opengl application which synchronizes buffer swaps against the vertical sync interrupt. In my testing, a lockup always results after running anywhere from 5 minutes to an hour and a half. I believe dual-head is needed to really trigger the problem because then the vertical sync interrupt handling is no longer predictable (due to being interrupt-sourced from two different heads running at different speeds). This raises the probability of the tasklet trying to run while the userspace DRI is doing things to the GPU (and manipulating the DRM lock). The fix is to change the relevant spinlock semantics to be the interrupt-blocking form. After this change I am no longer able to trigger the lockup; the longest test run so far was 20 hours (test stopped after that point). Note: I have examined the places where this spinlock is being employed; all are reasonably short bounded sequences and should be suitable for interrupts being blocked without impacting overall kernel interrupt response latency.

2008-03-05drm: Fix for non-coherent DMA PowerPCBenjamin Herrenschmidt
This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors. It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.
