2008-07-26r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEXNicolai Haehnle
DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

2008-07-25drm: don't set the signal blocker on the master process.Dave Airlie
this lets us debug the X server through xkb startup. Not sure what the correct answer is, probably X needs to drop the lock when execing stuff, with input hotplug it can get xkb stuff at any time I believe.

2008-07-23i915: Move all of the irq install/uninstall to load time.Robert Noland
This resolves a panic on FreeBSD which was caused by trying to re-initialize the swap lock. It's just much easier to initialize all of the locks at load time. It should also ensure that the vblank structures are available earlier.

The driver code that caused this is no longer necessary and has been dropped.
2008-07-21radeon: Post-vblank-rework-rework cleanups.Michel Dänzer
Thanks to the reworked vblank-rework, we can just use the hardware frame counter directly, and make the RADEON_PARAM_VBLANK_CRTC getparam just return what was set by the corresponding setparam.
2008-07-21vblank-rework rework cleanups.Michel Dänzer
Remove some dead/obsolete code and make drm_update_vblank_count() static.
2008-07-21Remove obsolete dev->vblank_suspend[crtc] tests.Michel Dänzer
Caused drm_update_vblank_count() not to do its thing when called from drm_modeset_ctl() -> drm_vblank_get(). The vblank functionality no longer needs to be suspended during a modeset, so rename the field to vblank_inmodeset.
2008-07-19i915: convert to using drm_vblank_get/put around vblank counter usageJesse Barnes
All interrupt off vblank count updates are done in drm_vblank_get/put now, so convert users of the vblank counter over to that interface.
2008-07-19Update vblank code to new APIJesse Barnes
In my last push I forgot to convert users of drm_update_vblank_count over to drm_vblank_get/put, since that's where any interrupt off->on update accounting is done now. Since the modeset ioctl did something similar (an open coded update of the counter) convert it over to using get/put too, which saves us from having to deal with every combination of interrupt off & on between calls.

2008-07-17[FreeBSD] drm_irq.c updates for vblank fixes.Robert Noland
2008-07-17i915: remove old broken vblank codeJesse Barnes
Remove the unused (and broken) "in vblank" code now that the core has been fixed to use a counter while interrupts are enabled. Also make the vblank pipe get/set ioctls into dumb stub functions, since with the new code we can no longer let userspace control whether vblank interrupts are enabled, or the core code will misbehave.
2008-07-17Avoid incorrect vblank wakeupsJesse Barnes
The current code uses the hw vblank counter exclusively, which can lead to wakeups during the active period rather than during the vblank period if the hw counter counts displayed frames rather than vblank periods. This change coverts the code over to using the counter while interrupts are enabled, fixing that issue. It also includes a couple of related changes: one to not enable the new enable/disable behavior until the modeset ioctl is called (to preserve old client behavior) and another to account for lost events due to mode setting with the new counter scheme. BSD will require similar changes to its drm_irq.c code, but they should be straightforward.

2008-07-16BSD: change drm_locked_task*() to use the same scheme as linux.Owain Gordon Ainsworth
The current code can sleep in an interrupt handler, that is bad. So instead if we can't grab the lock, flag it and run the tasklet on unlock. Signed-off-by: Robert Noland <rnoland@2hip.net>

2008-07-15This is a modified version of Hong's patch from last month, with a fewHong Liu
modifications to make it work correctly on my test hardware (altered the backlight write function, made it enable the legacy backlight controller interrupts on mobile hardware, sorted the interrupt function so we don't get an excessive number of vblank interrupts). This lets the backlight keys on my T61 work properly, though there's a 750msec or so delay between the request and the brightness actually changing - this sounds awfully like the hardware spinning waiting for a status flag to become ready, but as far as I can tell they're all set correctly. If anyone can figure out what's wrong here, it'd be nice to know. Some of the functions are still stubs and just tell the hardware that the request was successful. These can be filled in as kernel modesetting gets integrated. I think it's worth getting this in anyway, since it's required for backlight control to work properly on some new platforms.

2008-07-01i915: only use tiled blits on 965+Jesse Barnes
When scheduled swaps occur, we need to blit between front & back buffers. I the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit, only on 965 chips, since it will cause corruption on pre-965 (e.g. 945).

2008-06-25nv50: when destroying a channel make sure it's not still current on PFIFOBen Skeggs
We won't get a PFIFO context switch when the same channel ID is recreated if the hw still thinks the channel is already active, which causes fun issues. Should allow X to be stopped and started without tearing down the entire card state in lastclose().

2008-06-24i915: register definition & header file cleanupJesse Barnes
It would be nice if one day the DRM driver was the canonical source for register definitions and core macros. To that end, this patch cleans things up quite a bit, removing redundant definitions (some with different names referring to the same register) and generally tidying up the header file.

2008-06-23nv50: use same dma object for fb/tt accessBen Skeggs
We depend on the VM fully now for memory protection, separate DMA objects for VRAM and GART are unneccesary. However, until the next interface break (soon) a client can't depend on the objects being the same and must still call NV_OBJ_SET_DMA_* methods appropriately.
2008-06-23nouveau: allocate drm-use vram buffers from end of vram.Ben Skeggs
This avoids seeing garbage from engine setup etc before X gets around to pointing the CRTCs at a new scanout buffer. Not actually a noticable problem before G80 as PRAMIN is forced to the end of VRAM by the hardware already.
