Thomas Hellstrom 6b289db054 Remove debug printout. 2007-02-13 20:47:30 +01:00
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?

2007-02-01 00:38:57 +01:00
Thomas Hellstrom 3024f23c65 memory manager: Make device driver aware of different memory types.
Memory types are either fixed (on-card or pre-bound AGP) or not fixed
(dynamically bound) to an aperture. They also carry information about:

1) Whether they can be mapped cached.
2) Whether they are at all mappable.
3) Whether they need an ioremap to be accessible from kernel space.

In this way VRAM memory and, for example, pre-bound AGP appear
identical to the memory manager.

This also makes support for unmappable VRAM simple to implement.

Thomas Hellstrom 540c64c378 Bugfixes. 2006-10-12 16:10:47 +02:00
Thomas Hellstrom 10150df02b Simplify the AGP backend interface somewhat.
Fix buffer bound caching policy changing, Allow
on-the-fly changing of caching policy on bound buffers if the hardware
supports it.

Allow drivers to use driver-specific AGP memory types for TTM AGP pages.
Will make AGP drivers much easier to migrate.

Thomas Hellstrom 3070389367 Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is that
it will go away in the mainstream kernel.
Some bugfixes, mainly in error paths.

Thomas Hellstrom f2db76e2f2 Big update:
Adapt for new functions in the 2.6.19 kernel.
Remove the ability to have multiple regions in one TTM.
   This simplifies a lot of code.
Remove the ability to access TTMs from user space.
   We don't need it anymore without ttm regions.
Don't change caching policy for evicted buffers. Instead change it only
   when the buffer is accessed by the CPU (on the first page fault).
   This tremendously speeds up eviction rates.
Current code is safe for kernels <= 2.6.14.
Should also be OK with 2.6.19 and above.

George Sapountzis f3deef730d Bug 6242: [mach64] Use private DMA buffers, part #3.
Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional
flag is needed, since PCI DMA buffers do not have an associated map.

Thomas Hellstrom eacedf41a6 Make the user_token 44-bit for TTMs, and have them occupy a unique file space
starting at 0x00100000000. This will hopefully allow us to use
unmap_mapping_range(). Note that user-space will need
64-bit file offset support.

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.

Michel Dänzer ed82172378 Core vsync: Add flag DRM_VBLANK_NEXTONMISS.

This makes it easier for userspace to know when it needs to allocate an ID.

Also free drawable information memory when it's no longer needed.

Actually make the existing ioctls for adding and removing drawables do
something useful, and add another ioctl for the X server to update drawable

Michel Dänzer 596d7e9984 Add support for secondary vertical blank interrupt to i915 driver.
When the vertical blank interrupt is enabled for both pipes, pipe A is
considered primary and pipe B secondary. When it's only enabled for one pipe,
it's always considered primary for backwards compatibility.

This will be used by the X server when, for example, switching vts.
