2008-06-22agp: use true/false instead of TRUE/FALSEDave Airlie
2008-06-20drm: only use kernel ioctl cmd when doing a core ioctl.Dave Airlie
Need to overhaul the mess that is driver ioctls
2008-06-20drm: fix the ioctl to not believe userspace.Dave Airlie
believing userspace causes oopses
2008-06-12xgi: Bump kernel versionIan Romanick
This should have been bumped when the fence interface was changed the other day. Better late than never, I suppose.

2008-06-03vblank: Don't wait or update the counter while the CRTC is supposedly disabled.Michel Dänzer
Without kernel modesetting, this requires cooperation of the userspace modesetting driver. We may have to leave the vblank interrupt enabled otherwise to avoid problems.
2008-06-03vblank: Clean up compensation for spurious wraparounds of driver counter.Michel Dänzer
Only compensate when the driver counter actually appears to have moved backwards. The compensation deltas need to be incremental instead of absolute; drop the vblank_offset field and just use atomic_sub().
2008-06-03vblank: Special-case driver vblank counter going back by 1.Michel Dänzer
Turns out the radeon driver is affected by the same problem that prompted i915 to revert to less useful counter flipping at the end of the vblank interval. In the long term, we can hopefully implement more reliable methods to achieve counter flipping at the beginning of vblank, but otherwise this should be an acceptable workaround.
2008-06-03vblank: Don't return current sequence number and time if interrupted by signal.Michel Dänzer
2008-06-03Revert "don't copy back if an error was returned."Michel Dänzer
This reverts commit 6671ad1917698b6174a1af314b63b3800d75248c. The vblank ioctl needs to update the userspace parameters when interrupted by a signal, which was prevented by this. Let's see if this breaks other ioctls...
2008-06-03drm/ati_pcigart: use proper page mapping functionDave Airlie
This should be pci_map_page not pci_map_single
2008-05-28radeon: split microcode out into a separate header file.Dave Airlie
2008-05-14ati_pcigart: oops wrong way around not that it actually matteredDave Airlie
2008-05-14ati_pcigart: stop working in the evenings you mess up too oftenDave Airlie
2008-05-14Revert "ati_pcigart: fixup properly this version might even work"Dave Airlie
This reverts commit bc0836e12a9790f1cc83f8bc29bc05043c4bc840. tree has some kref hacks in it - oops
2008-05-14ati_pcigart: fixup properly this version might even workDave Airlie
2008-05-14ati_pcigart: fill out 40-bit gart table support properlyDave Airlie
Thanks to Alex for supplying this info.
2008-05-07drm: nopage compat fixup for drm_vmDave Airlie
The kernel has removed nopage so move the old nopage codepaths into a compat vm file and switch to using the fault paths. nopfn is on its way out in the future also, so we should switch to using fault for that path as well soon
2008-04-29i915: fix off by one in VGA save/restore of AR & CR regsJesse Barnes
Turns out it's important to save/restore AR14 in particular.
2008-04-27Use fixed sized types in new ioctlsJesse Barnes
Make both crtc and the command argument 32 bits to avoid any 32-on-64 compat issues.

2008-04-23Fixed unlock check on EAGAINJakob Bornecrantz
2008-04-22linux-core Makefile: add GIT_REVISIONPekka Paalanen
This tries to automatically fetch a git revision string and if succeeds, it #defines GIT_REVISION string macro. Packagers can override it by 'make GIT_REVISION=foo'. Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE in struct drm_driver. Signed-off-by: Pekka Paalanen <pq@iki.fi>
2008-04-14Fix buffer object map wait error.Thomas Hellstrom

2008-04-14Unlock the BO mutex while waiting for idle, unmapped, unfenced.Thomas Hellstrom
Move unfenced checking into idle checking. Never time out while waiting for software events like unmapped or unfenced.

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.

2008-03-17Evict cached_mapped relocatee before applying reloc.Thomas Hellstrom
Fix that got left out after the intel-post-reloc merge.
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.
