Commit 9b01bd5b284bbf519b726b39f1352023cb5e9e69 introduced a
compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was
to handle the fact that on i386, alignof(uint64_t)==4.
Unfortunately, this handler was installed for _all_ 64-bit
architectures, instead of only x86_64 and ia64. And thus it breaks
32-bit compatibility on every other arch, where 64-bit integers are
aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode.
Arnd has a cunning plan to use 'compat_u64' with appropriate alignment
attributes according to the 32-bit ABI, but for now let's just make the
compat_radeon_cp_setparam routine entirely disappear on 64-bit machines
whose 32-bit compat support isn't for i386. It would be a no-op with
compat_u64 anyway.

If the driver doesn't support vertical blank interrupts, it won't call
drm_vblank_init(), and dev->num_crtcs will be 0.
Also fix an off-by-one test against dev->num_crtcs.

Also use drm_calloc instead of drm_alloc and memset, and use the size of the
struct instead of the size of the pointer for allocation...
|
|
- use correct refcount variable in get/put routines
- extract counter update from drm_vblank_get
- make signal handling callback per-crtc
- update interrupt handling logic, drivers should use drm_handle_vblank
- move wakeup and counter update logic to new drm_handle_vblank routine
- fixup usage of get/put in light of counter update extraction
- fix longstanding bug in signal code, update pending counter only
*after* we're sure we'll setup signal handling

|
|
|
- move pre/post modeset ioctl to core
- fixup i915 buffer swap
- fix outstanding signal count code
- create new core vblank init routine
- test (works with glxgears)
- simplify i915 interrupt handler

of vblank interrupt in order to save power.

Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.
64-bit wide buffer object flag member.

This reverts commit 6e860d08d0f5b1e9a2d711aaf9fd6b982aa8039e.
As I said not a good plan - this macro will have to stay for now,
trying to do the vbl code with the inline was a bit messy - may need specialised
drm wait on functions
|
|
This add support for CRTC2 vblank on radeon similiar to the i915 support
|
|
|

|
This cleans this code up a lot and uses the generic Linux idr which is
designed for this.

This is the first bunch of ioctls

This makes the drms use of the list handling macros a lot cleaner
and more along the lines of how they should be used.

also we should fail if we can't enable the device at resume time.

held across any operations that modify mode lists, crtc config, output
config, etc. It should be taken at high level entry points (currently just
initial config and user IOCTL).
Seems to work ok on my system, but needs more testing (with lockdep) and
review from some fresh eyes.
