2009-07-15drm/via: Fix vblank IRQ on VIA hardware.Simon Farnsworth
via_enable_vblank wasn't setting the VBlank enable bit - instead, it was masking out the rest of the register. At the same time, fix via_disable_vblank to clear the VBlank enable bit. Signed-off-by: Dave Airlie <airlied@linux.ie>
2009-06-18drm: Remove memory debugging infrastructure.Eric Anholt
It hasn't been used in ages, and having the user tell your how much memory is being freed at free time is a recipe for disaster even if it was ever used. Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-12drm/via: vfree() no need checking before calling itFigo.zhang
vfree() does it's own NULL checking, no need for explicit check before calling it. Signed-off-by: Figo.zhang <figo1802@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-04-20drm: count reaches -1Roel Kluin
With a postfix decrement in the test count will reach -1 rather than 0, subsequent tests fail. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-03-13drm: Drop unused and broken dri_library_name sysfs attribute.Kristian Høgsberg
The kernel shouldn't be in the business of telling user space which driver to load. The kernel defers mapping PCI IDs to module names to user space and we should do the same for DRI drivers. And in fact, that's how it does work today. Nothing uses the dri_library_name attribute, and the attribute is in fact broken. For intel devices, it falls back to the default behaviour of returning the kernel module name as the DRI driver name, which doesn't work for i965 devices. Nobody has ever hit this problem or filed a bug about this. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2008-11-25drm: move drm vblank initialization/cleanup to driver load/unloadKeith Packard
drm vblank initialization keeps track of the changes in driver-supplied frame counts across vt switch and mode setting, but only if you let it by not tearing down the drm vblank structure. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-10-18drm: kill drm_device->irqJesse Barnes
Like the last patch but adds a macro to get at the irq value instead of dereferencing pdev directly. Should make things easier for the BSD guys and if we ever support non-PCI devices. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-10-18drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes
Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

2008-07-14drm: reorganise drm tree to be more future proof.Dave Airlie
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
