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
2008-02-27Reinstate buffer idle before applying relocations.Thomas Hellstrom
2008-02-27Don't wait for buffer idle before applying relocations.Thomas Hellstrom
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.
2008-02-22Fix one last occurance of struct _drm_i915_batchbuffer.Kristian Høgsberg
Thanks to Todd Merrill for pointing it out.
2008-02-13i915: Add a dri2 init path that gets the lock from the dri2 sarea.Kristian Høgsberg

2008-02-13i915: Make sarea_priv setup optional.Kristian Høgsberg
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.
2008-01-30i915: 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.
2008-01-24i915: fix missing header when copying data from userspaceDave Airlie
2008-01-24i915 make relocs use copy from userDave Airlie
Switch relocs to using copy from user and remove index and pass buffer handles in instead.
2008-01-15Properly propagate the user-space fence flags.Thomas Hellstrom
This avoids a sync flush when user-space has already programmed and MI_FLUSH in the batchbuffer.
2008-01-03drm: cleanup DRM_DEBUG() parametersMárton Németh
As DRM_DEBUG macro already prints out the __FUNCTION__ string (see drivers/char/drm/drmP.h), it is not worth doing this again. At some other places the ending "\n" was added. airlied:- I cleaned up a few that this patch missed also
2007-12-15Document drm_bo_handle_validate. Match drm_bo_do_validate parameter order.Keith Packard
Document parameters and usage for drm_bo_handle_validate. Change parameter order to match drm_bo_do_validate (fence_class has been moved to after flags, hint and mask values). Existing users of this function have been changed, but out-of-tree users must be modified separately.
2007-12-11Make relocation validate client computed values when debuggingKeith Packard
2007-12-11i915: wait for buffer idle before writing relocationsKeith Packard
When writing a relocation entry, make sure the target buffer is idle, otherwise the GPU may see inconsistent data.
2007-12-11Allow relocation to be skipped when buffers don't move.Keith Packard
One of the costs of superioctl has been the need to perform relocations inside the kernel. The cost of mapping the buffers to the CPU and writing data is fairly high, especially if those buffers have been mapped and read by the GPU. If we assume that buffers don't move around very often, we can have the client compute the relocations itself using the previous GPU address. When that object doesn't move, the kernel can skip computing and writing the updated data. Here's a patch which adds a new field to struct drm_bo_info_req called 'presumed_offset', and a new DRM_BO_HINT_PRESUMED_OFFSET that is set when this field has been filled in by the client. There are two separate optimizations performed when the presumed_offset is correct: 1. i915_exec_reloc checks to see if all previous buffer offsets were guessed correctly. If so, there's no need for it to look at *any* of the relocations for a buffer. When this happens, it skips the whole relocation process, simply returning success. 2. i915_apply_reloc checks to see if the target buffer offset was guessed correctly. If so, it skips mapping the relocatee, computing the relocation and writing the value. If no relocations are needed, the relocatee should never be mapped to the CPU, and so the kernel shouldn't need to wait for any fences to pass.
2007-12-05Remove references to the sarea_priv perf_boxes field.Kristian Høgsberg
This field isn't touched or read by any other code in the stack so it's time to retire these last few references.

2007-12-01drm: Add _DRM_DRIVER map flag.Robert Noland
This flag indicates that the driver is responsible for the map.
2007-11-29Beside the emitted warning, the added cast (u64 -> unsigned) strips outJiri Slaby
part of address on 64 bit. Cast to unsigned long instead. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2007-10-26i915: suspend/resume supportJesse Barnes
Add suspend/resume support to the i915 driver. Moves some of the initialization into the driver load routine, and fixes up places where we assumed no dev_private existed in some of the cleanup paths. This allows us to suspend/resume properly even if X isn't running.
