c153f45f9b drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.
The data is now in kernel space, copied in/out as appropriate according to t
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures.  This also means that XFree86 4.2.0 support for i810 DR
is lost.

6c340eac02 drm: Replace filp in ioctl arguments with drm_file *file_priv.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everyth
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct
went the other direction.

20caafa6ec drm: Remove DRM_ERR OS macro.
This was used to make all ioctl handlers return -errno on linux and errno on
*BSD.  Instead, just return -errno in shared code, and flip sign on return f
shared code to *BSD code.

e4a7b1d1d9 i915: make vbl interrupts work properly on i965g/gm hw.
This code is ported from the DRM git tree and allows the vblank interrupts
to function on the i965 hw. It also requires a change in Mesa's 965 driver
to actually use them.

[ Without this patch, my 965GM drops vblank interrupts  - Jesse ]

c60ce623bd drm: remove a bunch of typedefs on the userspace interface
This moves a bunch of typedefs into a !defined __KERNEL__ to keep userspace
API compatiblity, it changes all internal usages to structs/enum/unions.

3188a24c25 i915_vblank_tasklet: Try harder to avoid tearing.
Previously, if there were several buffer swaps scheduled for the same vertical
blank, all but the first blit emitted stood a chance of exhibiting tearing. In
order to avoid this, split the blits along slices of each output top to bottom.

2228ed6722 drm: i915 updates
Add support for DRM_VBLANK_NEXTONMISS.
Bump minor for swap scheduling ioctl and secondary vblank support.
Avoid mis-counting vblank interrupts when they're only enabled for pipe A.
Only schedule vblank tasklet if there are scheduled swaps pending.

5b51694aff drm: Make handling of dev_priv->vblank_pipe more robust.
Initialize it to default value if it hasn't been set by the X server yet.

In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call
i915_enable_interrupt() if the argument passed from userspace is valid to avoid
corrupting dev_priv->vblank_pipe on invalid arguments.

541f29aad7 drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead
of pipe number.

Handle relative as well as absolute target sequence numbers.

Return error if target sequence has already passed, so userspace can deal with
this situation as it sees fit.

On success, return the sequence number of the vertical blank when the buffer
swap is expected to take place.

Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want
to use ioctl() instead of drmCommandWriteRead().

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
