This cleans up the create/validate interfaces for this very uncommon path, and
makes pinned object creation much easier to use for the X Server.
|
|
|
|
This might break something, stdint.h inclusion in drm.h maybe required
but I'm not sure yet what platforms have it what ones don't.

Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.
64-bit wide buffer object flag member.
|
|
retain the op operation for validate/fence operations
|
|
This just cleans up the xf86drm.c to what I want and drm.h,
I need to fix up the kernel internals to suit these changes now.
I've moved to using struct instead of typedefs for the bo and it doesn't look
that bad so I'll do the same thing for mm and fence..

The xserver no longer uses the libc-wrapper.

Used to request that a scheduled buffer swap be done as a flip instead of a
blit.

Flag handling and memory type selection cleanup.
glxgears won't start.

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.

Bump libdrm version number to 2.2.0
|
|
This will come in very handy for tiled buffers on intel hardware.
Also add some padding to interface structures to allow future binary backwards
compatible changes.

that is now handled by the memory accounting.

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.

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.
|
|
When this flag is set and the target sequence is missed, wait for the next
vertical blank instead of returning immediately.

Actually make the existing ioctls for adding and removing drawables do
something useful, and add another ioctl for the X server to update drawable
information. The only kind of drawable information tracked so far is cliprects.

Change the fence object interface somewhat to allow some more flexibility.
Make list IOCTLS really restartable.
Try to avoid busy-waits in the kernel using immediate return to user-space with an -EAGAIN.

Disable the i915 IRQ turnoff for now since it seems to be causing problems.

Remove option to wait for fence / buffers and block signals.
