2008-07-21Reinstate dev->vblank_enabled[].Michel Dänzer
I incorrectly thought it was obsolete.
2008-07-21Drop workaround for driver vblank counter going backwards.Michel Dänzer
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.
2008-07-18drm-gem: Fix buildIan Romanick
On some distros missing prototypes cause kernel builds to fail. These are hack to make the code build.

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.

2008-07-14intel-gem: Disable tiling if we get junk from the MCHBAR read.Eric Anholt
One of our systems has been returning 0xffffffff from all MCHBAR reads, which means we'll need to figure out why, or add an alternate detection method.
2008-07-11intel-gem: Add two new ioctls for managing tiling on objects.Eric Anholt
Various chips have exciting interactions between the CPU and the GPU's different ways of accessing interleaved memory, so we need some kernel assistance in determining how it works. Only fully tested on GM965 so far.

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).

2008-07-01i915: enable bus mastering on i915 at resume timeJie Luo
On 9xx chips, bus mastering needs to be enabled at resume time for much of the chip to function. With this patch, vblank interrupts will work as expected on resume, along with other chip functions.

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().
2008-06-24[intel] Get vblank pipe from irq_mask_reg instead of hardware enable regKeith Packard
With the interrupt enable/disable using only the mask register, it was wrong to use the enable register to detect which pipes had vblank detection turned on. Also, as we keep a local copy of the mask register around, and MSI machines smack the hardware during the interrupt handler, it is more efficient and more correct to use the local copy.

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.
