Michel Dänzer 82e2c3304d Wake up vblank waitqueue in drm_handle_vblank(). 2007-06-15 10:25:50 +02:00
Michel Dänzer 7f95a06c61 Return current sequence number to userspace after blocking wait for vblank. 2007-06-15 10:12:23 +02:00
Michel Dänzer 1000d88ddf Fix memory leaks in vblank error paths.
Also use drm_calloc instead of drm_alloc and memset, and use the size of the
struct instead of the size of the pointer for allocation...

Jesse Barnes b06268294a Comment new vblank routines and fixup several issues:
- use correct refcount variable in get/put routines
  - extract counter update from drm_vblank_get
  - make signal handling callback per-crtc
  - update interrupt handling logic, drivers should use drm_handle_vblank
  - move wakeup and counter update logic to new drm_handle_vblank routine
  - fixup usage of get/put in light of counter update extraction
  - fix longstanding bug in signal code, update pending counter only
    *after* we're sure we'll setup signal handling

Dave Airlie 7b48f0022a drm: cleanup use of Linux list handling macros
This makes the drms use of the list handling macros a lot cleaner
and more along the lines of how they should be used.

Thomas Hellstrom e1460426b8 Bugzilla Bug #9457
Add refcounting of user waiters to the DRM hardware lock, so that we can use the
DRM_LOCK_CONT flag more conservatively.

Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context,
when it is released. This is useful when waiting for idle and can be used
for very simple fence object driver implementations for the new memory manager.

It also resolves the AIGLX startup deadlock for the sis and the via drivers.
i810, i830 still require that the hardware lock is really taken so the deadlock remains
for those two. I'm not sure about ffb. Anyone familiar with that code?

Michel Dänzer 3a16e615ca Make locked tasklet handling more robust.
Initialize the spinlock unconditionally when struct drm_device is filled in,
and return early in drm_locked_tasklet() if the driver doesn't support IRQs.

Michel Dänzer cef0f24325 Core vsync: Don't clobber target sequence number when scheduling signal.
It looks like this would have caused signals to always get sent on the next
vertical blank, regardless of the sequence number.

Dave Airlie 805a07714f misc cleanup patch from Adrian Bunk 2005-06-04 06:18:11 +00:00
Thomas Hellstrom 532ccb98b5 Via updates:
New PCI command parser. Moved from via_dma.c to via_verifier.c so functions
    with similar functionality are close to eachother.
Moved video related functions to via_video.c, which might be extended in
    the future, as new video functionality is added.
New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL,
    but with support for multiple device IRQ sources and functionality.
Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and
    PCI parser.
Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ
    IOCTL.
Bumped minor. New version 2.6.0.

Alan Hourihane a41a479f74 Changes to DRM(irq_install)...... wrap dev->dma usage with __HAVE_DMA in
irq handler, fixes kernel ooops. comment out some setting of flags that
    are done in DRM(setup) (not sure why both of the above is done in the
    irq handler)
2003-11-05 20:47:28 +00:00
Eric Anholt 66c9e3053f - Tie the DRM to a specific device: setunique no longer succeeds when given
a busid that doesn't correspond to the device the DRM is attached to.
    This is a breaking of backwards-compatibility only for the
    multiple-DRI-head case with X Servers that don't use interface 1.1.
- Move irq_busid to drm_irq.h and make it only return the IRQ for the
    current device. Retains compatibility with previous X Servers, cleans
    up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be
    changed if necessary.
- Bump interface version to 1.2. This version when set signifies that the
    control ioctl should ignore the irq number passed in and enable the
    interrupt handler for the attached device. Otherwise it errors out when
    the passed-in irq is not equal to the device's.
- Store the highest version the interface has been set to in the device.
- Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves
    irq_uninstall being done without the lock in some cases, but it was
    racey anyways.

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.
