drm/radeon: fix correctness of irq_enabled check for radeon.

2008-12-23T00:50:12+00:00

This check was introduced with the logic the wrong way around.

drm/radeon: don't actually enable the IRQ regs until irq is enabled

2008-12-09T05:30:50+00:00

vblank can try and enable the IRQ registers before we've set the interrupt
handler up.

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.

drm/radeon: map registers at load time

2008-11-11T07:56:16+00:00

Now that the radeon driver has suspend/resume functions, it needs to map its
registers at load time or it will likely crash if a suspend operation occurs
before the driver has been initialized.

This patch moves the register mapping code from firstopen to load and makes
the mapping into a _DRM_DRIVER one so that the core won't remove it at
lastclose time.

Fixes (at least partially) kernel bz #11891.

drm/radeon: fixup further bus mastering confusion.

2008-10-27T21:48:34+00:00

rs400/480 are like previous chips not like rs6xx chips.

radeon: fix PCI bus mastering support enables.

2008-10-17T21:10:54+00:00

Someone noticed these registers moved around for later chips,
so we redo the codepaths per-chip. PCIE chips don't appear to
require explicit enables.

radeon: add RS400 family support.

2008-10-17T21:10:54+00:00

This adds support for the RS400 family of IGPs for Intel CPUs.

drm/radeon: add support for RS740 IGP chipsets.

2008-10-17T21:10:54+00:00

This adds support for the HS2100 IGP chipset.

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.

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.
