This still isn't perfect but it fixes a few oopses and cleans up
some of the tabs and bugs in the original fb limit code
|
|
|
|
Originally from Jakob, cleaned up by airlied.
|
|
This hooks up the userspace mode set it "seems" to work.
|
|
This adds the user interfaces from Jakob and hooks them up for 3 ioctls
GetResources, GetCrtc and GetOutput.
I've made the ids for everything fbs, crtcs, outputs and modes go via idr as
per krh's suggestion on irc as it make the code nice and consistent.

Used to request that a scheduled buffer swap be done as a flip instead of a
blit.
|
|
Buffer object driver for via.
Some changes to buffer object driver callbacks.
Improve fence flushing.
|
|
(Fence objects belonging to different command submission mechanisms).

|
This adds APIs to allow the X server to use libdrm from the system
rather than its own in-built copy.
|
|
|
|
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.

|
The mm_lock function is used when leaving vt. It evicts _all_ buffers.
Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to
get the same offset when / if they are rebound.
|
|
Fix up init and destruction code.
|
|
it will go away in the mainstream kernel.
Some bugfixes, mainly in error paths.
|
|
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.
|
|
starting at 0x00100000000. This will hopefully allow us to use
unmap_mapping_range(). Note that user-space will need
64-bit file offset support.
|
|
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.

(Disabled for now)
Fix bo_wait_idle bug.
Remove stray debug message.
|
|
Add a buffer object waitIdle user-space function.
Fix some names and minor glitches.
|
|
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.
|

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

Add an info ioctl operation.
