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.
2008-07-15This 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.

2008-07-01Revert "i915: only use tiled blits on 965+"Jesse Barnes
This reverts commit 727d4f1d1667e43b3558bd5f6ed6dc2cd9c29401, somehow git deleted the symlink and replaced it with the file.
2008-07-01i915: only use tiled blits on 965+Jesse Barnes
When scheduled swaps occur, we need to blit between front & back buffers. If the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit, but 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.
