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.
2008-07-21vblank-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.
2008-07-19Update 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.
2008-07-17Avoid 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.

2008-07-01Revert "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). Bug reported by and fix tested by Tomas Janousek <tomi@nomi.cz>. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
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. Fixes kernel bugzilla #10844. Signed-off-by: Jie Luo <clotho67@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2008-06-24i915: remove unused variableJesse Barnes
Leftover dev_priv from the move of the suspend/resume code into shared-core.
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.

2008-06-20drm: only use kernel ioctl cmd when doing a core ioctl.Dave Airlie

believing userspace causes oopses

This should have been bumped when the fence interface was changed the other day. Better late than never, I suppose.

2008-06-03vblank: Don't wait or update the counter while the CRTC is supposedly disabled.Michel Dänzer
Without kernel modesetting, this requires cooperation of the userspace modesetting driver. We may have to leave the vblank interrupt enabled otherwise to avoid problems.
2008-06-03vblank: Clean up compensation for spurious wraparounds of driver counter.Michel Dänzer
Only compensate when the driver counter actually appears to have moved backwards. The compensation deltas need to be incremental instead of absolute; drop the vblank_offset field and just use atomic_sub().
2008-06-03vblank: Special-case driver vblank counter going back by 1.Michel Dänzer
Turns out the radeon driver is affected by the same problem that prompted i915 to revert to less useful counter flipping at the end of the vblank interval. In the long term, we can hopefully implement more reliable methods to achieve counter flipping at the beginning of vblank, but otherwise this should be an acceptable workaround.
2008-06-03vblank: Don't return current sequence number and time if interrupted by signal.Michel Dänzer
2008-06-03Revert "don't copy back if an error was returned."Michel Dänzer
This reverts commit 6671ad1917698b6174a1af314b63b3800d75248c. The vblank ioctl needs to update the userspace parameters when interrupted by a signal, which was prevented by this. Let's see if this breaks other ioctls...

2008-05-07drm: nopage compat fixup for drm_vmDave Airlie
The kernel has removed nopage so move the old nopage codepaths into a compat vm file and switch to using the fault paths. nopfn is on its way out in the future also, so we should switch to using fault for that path as well soon
