drm: move drm vblank initialization/cleanup to driver load/unload

2008-11-24T23:49:03+00:00

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 Signed-off-by: Dave Airlie

drm: kill drm_device->irq

2008-10-17T21:10:53+00:00

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 Signed-off-by: Dave Airlie

drm: Rework vblank-wait handling to allow interrupt reduction.

2008-10-17T21:10:11+00:00

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.

drm: reorganise drm tree to be more future proof.

2008-07-14T00:45:01+00:00

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
