Dave Airlie 5b99306452 i915: fix missing header when copying data from userspace 2008-01-24 15:18:09 +10:00
Dave Airlie 34b71eb451 i915 make relocs use copy from user
Switch relocs to using copy from user and remove index and pass buffer
handles in instead.

Thomas Hellstrom 88c511e49d Properly propagate the user-space fence flags.
This avoids a sync flush when user-space has already programmed
and MI_FLUSH in the batchbuffer.

Márton Németh 9ab620d661 drm: cleanup DRM_DEBUG() parameters
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.

Keith Packard 5f23519b14 Document drm_bo_handle_validate. Match drm_bo_do_validate parameter order.
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.

Keith Packard 4ec8f58d04 i915: wait for buffer idle before writing relocations
When writing a relocation entry, make sure the target buffer is idle,
otherwise the GPU may see inconsistent data.
2007-12-11 20:23:00 -08:00
Keith Packard 57b9a54eb6 Allow relocation to be skipped when buffers don't move.
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.

Jiri Slaby 309b2c4c05 Beside the emitted warning, the added cast (u64 -> unsigned) strips out
part of address on 64 bit. Cast to unsigned long instead.

Jesse Barnes 1e2a2babab i915: suspend/resume support
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.
