2007-06-15Remove DRIVER_IRQ_VBL(2).Michel Dänzer
If the driver doesn't support vertical blank interrupts, it won't call drm_vblank_init(), and dev->num_crtcs will be 0. Also fix an off-by-one test against dev->num_crtcs.
2007-06-15Make vblank waitqueue per CRTC.Michel Dänzer
2007-06-15Wake up vblank waitqueue in drm_handle_vblank().Michel Dänzer
2007-06-15Return current sequence number to userspace after blocking wait for vblank.Michel Dänzer
2007-06-15Fix memory leaks in vblank error paths.Michel Dänzer
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...
2007-06-14Comment new vblank routines and fixup several issues:Jesse Barnes
- 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
2007-06-12Update vblank code:Jesse Barnes
- move pre/post modeset ioctl to core - fixup i915 buffer swap - fix outstanding signal count code - create new core vblank init routine - test (works with glxgears) - simplify i915 interrupt handler
2007-06-12Initial checkin of vblank rework. Code attempts to reduce the numberJesse Barnes
of vblank interrupt in order to save power.
2007-05-26drm: cleanup use of Linux list handling macrosDave Airlie
This makes the drms use of the list handling macros a lot cleaner and more along the lines of how they should be used.

2007-02-13Bugzilla Bug #9457Thomas Hellstrom
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?

2006-10-02Make locked tasklet handling more robust.Michel Dänzer
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.
2006-09-29Core vsync: Don't clobber target sequence number when scheduling signal.Michel Dänzer
It looks like this would have caused signals to always get sent on the next vertical blank, regardless of the sequence number. (cherry picked from cf6b2c5299e9be3542d4deddfd05d5811f11d2ef commit)
2006-09-29Core vsync: Add flag DRM_VBLANK_NEXTONMISS.Michel Dänzer
When this flag is set and the target sequence is missed, wait for the next vertical blank instead of returning immediately. (cherry picked from 89e323e4900af84cc33219ad24eb0b435a039d23 commit)

remove a mach64 warning, align a lot of things from linux kernel

2005-06-04misc cleanup patch from Adrian BunkDave Airlie
2005-03-28Via updates:Thomas Hellstrom
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.

2003-11-05Changes to DRM(irq_install)...... wrap dev->dma usage with __HAVE_DMA inAlan Hourihane
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- Tie the DRM to a specific device: setunique no longer succeeds when givenEric Anholt
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.
