Dave Airlie 91c6c4b240 rs690/r500: vblank support.
The new display controller has the vblank interrupts in a different place.

Add support for vbl interrupts for these chips

Márton Németh 9ab620d661 drm: cleanup DRM_DEBUG() parameters
As DRM_DEBUG macro already prints out the __FUNCTION__ string (see
drivers/char/drm/drmP.h), it is not worth doing this again. At some
other places the ending "\n" was added.

airlied:- I cleaned up a few that this patch missed also

Jesse Barnes 91aae7e683 Merge branch 'master' into vblank-rework, fixup remaining drivers

Merge in the latest master bits and update the remaining drivers (except
mach64 which math_b is working on).  Also remove the 9xx hack from the i915
driver; it seems to be correct.

Eric Anholt 5b38e13416 Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.
The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures.  This also means that XFree86 4.2.0 support for i810 DRM
is lost.

Eric Anholt c1119b1b09 Replace filp in ioctl arguments with drm_file *file_priv.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

Eric Anholt e39286eb5e Remove DRM_ERR OS macro.
This was used to make all ioctl handlers return -errno on linux and errno on
*BSD.  Instead, just return -errno in shared code, and flip sign on return from
shared code to *BSD code.

Michel Dänzer 5b726b6390 radeon: Improve vblank counter.
The frame counter seems to increase only at the end of vertical blank, so we
need to add 1 while in vertical blank.

Michel Dänzer 068ffc1e1b radeon: Acknowledge all interrupts we're interested in.
Failure to do so was probably the root cause of fd.o bug 11287.

Michel Dänzer b8dd314875 Remove mask parameter from radeon_acknowledge_irqs().
Simply always acknowledge all interrupts we're interested in, to avoid hard
hangs when an unexpected interrupt is flagged.

Jesse Barnes afe842297f RADEON: fix race in vblank interrupt handling
It's possible that we disable vblank interrupts and clear the
corresponding flag in irq_enable_reg, but receive an interrupt at just
the wrong time, causing us to not ack it properly, nor report to the
core kernel that it was handled.  Fix that case by always handling
vblank interrupts, even if the irq_enable_reg field is clear.

Michel Dänzer d8ed021d29 radeon: VBlank rework fixups.
Fix range of frame counter registers.

Use DRM_ERR() instead of Linux specific error codes in shared code.

Remove duplicate register definitions and superfluous local variables.

Eric Anholt c6344e8df5 Assert an MIT copyright on sis_drm.h, since one was lacking and I created
that particular file. Its contents have changed a good bit since the
    original sis code, and the original sis code didn't care much about
    attribution since it routinely disclaims Precision Insight/VA Linux
    from responsibility. Also, adjust formatting around license headers
    (have a comment open immediately before the "Copyright" line, not as a
    runon of any previous comments) for automatic processing into FreeBSD,
    where /*- is used to signal the beginning of license headers for
    automatic compilation of license lists.

Jon Smirl 9f9a8f1382 Lindent of core build. Drivers checked for no binary diffs. A few files
weren't Lindent's because their comments didn't convert very well. A
    bunch of other minor clean up with no code implact included.

Dave Airlie 02df04d71d sync up with current 2.6 kernel bk tree - mostly __user annotations 2004-07-25 08:47:38 +00:00
Eric Anholt 2950f9e682 - Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle them
from __HAVE_DMA. This will be useful for adding vblank sync support to
    sis and tdfx. Rename dma_service to irq_handler, which is more
    accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
    the right number of underscores. This may have been a problem in the
    case that the server died without doing its DRM_IOCTL_CONTROL to
    uninit.

Leif Delgass f2a0c5438d Ensure driver has been initialized (dev_private != NULL) before installing
irq handler in DRM(irq_install). Modify all drivers to ensure irq
    handler is removed before cleanup and cleanup is called at takedown.
    Remove unused buffer private struct fields in i810, i830. Check for
    lock on init/cleanup in all drivers except i810/i830. The current DDX
    for i810 and i830 doesn't hold the lock on kernel init (FIXME?).
