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.

2008-03-06ttm: make sure userspace can't destroy kernel create memory managersDave Airlie
this adds something to say the kernel initialised the memory region not the userspace. and blocks userspace from deallocating kernel areas
2008-03-06drm/ttm: add ioctl to get back memory managed area sizedDave Airlie
taken from modesetting branch but could be useful outside it.
2008-03-06drm: reorganise minor number handling using code from modesetting branchDave Airlie
Rip out the whole head thing and replace it with an idr and drm_minor structure.
2008-03-05i915: Evict if relocatee buffer is CACHED_MAPPED beforeXiang, Haihao
writting relocations, otherwise the GPU probably sees some inconsistent data. Fix fd.o bug#14656
2008-03-04Clarify when WAIT_LAZY is relevant to users.Eric Anholt
2008-03-04Remove unused DRM_FENCE_FLAG_WAIT_IGNORE_SIGNALS.Eric Anholt
2008-03-04Clarify through the names what drm_ttm_alloc_pages() and friend actually did.Eric Anholt
These are all about the page directory (pointers to pages) rather than the actual pages backing the allocation.
2008-03-04Don't shortcut the info syscall for drmBOBusy on nonshareable objects.Eric Anholt
This broke the results when you're trying to check if a buffer you dispatched some time ago is done being rendered from.
2008-03-03 [i915] 2D driver may reset Frame count value, this may lead driverZou Nan hai
to leap it's vblank count a huge value. This will stall some applications that switch video mode if vblank_mode is set to a non zero value in drirc.

2008-02-28Add a compat kmap_atomic_prot_pfn to do quick kernel map / unmaps ofThomas Hellstrom
PCI- or high memory. This is substantially more efficient than drm_bo_kmap, since the mapping only lives on a single processor. Unmapping is done use kunmap_atomic(). Flushes only a single tlb() entry. Add a support utility int drm_bo_pfn_prot() that returns the pfn and desired page protection for a given bo offset. This is all intended for relocations in bound TTMS or vram. Mapping-accessing-unmapping must be atomic, either using preempt_xx() macros or a spinlock.

2008-02-26[i915] Relocation fixes.Thomas Hellstrom
2008-02-26Make the execbuffer code reasonably safe against errors.Thomas Hellstrom
In particular -EAGAINs, which should be common during Xserver operation. Also handle the fence creation failure case.
2008-02-23fix texture uploads with large 3d textures (bug 13980)Roland Scheidegger
Texture uploads could hit the blitter coordinate limit, adjust the texture offset when uploading the pieces. Make sure to check the end address of the upload too.
2008-02-22i915: put ARX back into index mode before doing restoreJesse Barnes
Fixes resume from hibernate in some configurations.
2008-02-22nouveau: Remove some random (french) comment.Maarten Maathuis
2008-02-22nouveau: A single define of dma skips is more than enough.Maarten Maathuis
2008-02-22Fix one last occurance of struct _drm_i915_batchbuffer.Kristian Høgsberg
Thanks to Todd Merrill for pointing it out.
2008-02-22i915: Remove leading underscore from struct tags.Kristian Høgsberg
This matches the changes in mesa to use the system drm includes for the definitions of the drm ioctl structs.
2008-02-21Don't free irq resources until after we've unregistered the handler.Kristian Høgsberg
2008-02-21linux: Clean up vblank related resources from drm_irq_uninstall().Michel Dänzer
This fixes at least two problems: * The vblank_disable_fn timer callback could get called after the DRM was de-initialized, e.g. on X server shutdown. * Leak of vblank related resources when disabling and re-enabling the IRQ, e.g. on an X server reset.

2008-02-20drm: add support for passing state into the suspend hooks.Dave Airlie
fix i915 driver to use state for hibernate save avoidance. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-02-16[915]: more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)Keith Packard
Failing to preserve the MI_ARB_STATE register was causing FIFO underruns on the VGA output on my HP 2510p after resume.
2008-02-16nouveau: no GART on ia64 either.Stephane Marchesin
2008-02-16nv40: actually init all tile regs.Ben Skeggs
2008-02-13i915: Add a dri2 init path that gets the lock from the dri2 sarea.Kristian Høgsberg
2008-02-13i915: Only look up dev_priv->mmio_map if it's not already set upKristian Høgsberg
2008-02-13i915: Add I915_PARAM_CHIPSET_ID param to get chipset ID.Kristian Høgsberg
2008-02-13i915: Make sarea_priv setup optional.Kristian Høgsberg
2008-02-07Restore pipeconf regs unconditionallyJesse Barnes
On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume. So restore them unconditionally along with actually restoring pipe B's palette correctly.
2008-02-07Fix saveGR array sizeJesse Barnes
Make sure we have enough room for all the GR registers or we'll end up clobbering the AR index register (which should actually be harmless unless the BIOS is making an assumption about it).
2008-02-07i915: save/restore interrupt stateJesse Barnes
On resume, if the interrupt state isn't restored correctly, we may end up with a flood of unexpected or ill-timed interrupts, which could cause the kernel to disable the interrupt or vblank events to happen at the wrong time. So save/restore them properly.
2008-02-07Fix vblank enable/disable callbacksJesse Barnes
There were two problems with the existing callback code: the vblank enable callback happened multiple times per disable, making drivers more complex than they had to be, and there was a race between the final decrement of the vblank usage counter and the next enable call, which could have resulted in a put->schedule disable->get->enable->disable sequence, which would be bad. So add a new vblank_enabled array to track vblank enable on per-pipe basis, and add a lock to protect it along with the refcount + enable/disable calls to fix the race.
2008-02-05i915: Re-report breadcrumbs on poll to the fence manager,Thomas Hellstrom
since a breadcrumb may actually turn up before a corresponding fence object has been placed on the fence ring.
2008-02-04nouveau: make nv34 work every time, not just every 2nd timeStuart Bennett
And make nv30_graph_init a bit more like mmio-traces
2008-02-02nouveau: NV40 can/should now be able to run after the blob.Maarten Maathuis
- Moved the fix from the ddx to drm, because it seemed more appropriate. - Don't be shy, report if it works for you or not.
2008-01-31Add an fence_class_manager::last_queued_sequence member, since aThomas Hellstrom
sequence number may actually turn up before the corresponding fence object has been queued on the ring. Fence drivers can use this member to determine whether a sequence number must be re-reported.
2008-01-30i915: Avoid calling drm_fence_flush_old excessively.Thomas Hellstrom
2008-01-30Simplify the fencing code and differentiate between flushes andThomas Hellstrom
waiting types. Add a "command_stream_barrier" method to the bo driver.
2008-01-30nv40: some more nv67 changesBen Skeggs
With some luck the drm-side will be OK now for this chipset.
