me to match other drivers and avoid ifdeffing. The linux via_drv.c will
be moved from shared-core to linux-core soon by repocopy.

caller on fb / agp memory alloc and free. Otherwise malicious clients
can register allocations on other clients or free memory used by other
clients which will lead to severe memory manager inconsistensies.
1) Security fix: Stopped possible MMIO access to PCI DMA area for the
unichrome Pro.
2) Fixed an odd cpu usage problem by padding small AGP DMA submissions.
Bumped patchlevel.
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.
1. Initialize futex locks to zero on device init.
2. Remove some stray defines from via_drm.h
3. Prepare via_drm.h for drm client inclusion. The goal is to share a
common file with common definitions.
4. Sync shared / shared-core via_drm.h
5. Bump minor, because of the futex lock initialization.
Release video futexes when context is destroyed (This was previously done
by the X server).
Added New Unichrome Pro VIDEO DMA commands to the verifier.
Added Quiescent heavyweight lock mode.
bug in the cmdbuf_size ioctl. Modified ring-buffer jump code AGAIN, due
to new oddities discovered on the Unichrome Pro with faster processors.
Bumped patchlevel and driver date.
1. Improved security check of AGP texture adresses.
2. Hopefully last fix of ring-buffer jump oddities.
3. Added ioctl to check available space and command regulator lag in
ring-buffer. This is needed for 3D application responsiveness.
1. The command verifier was never initialized in the non-core source tree.
2. Check added that the AGP ring buffer has been initialized before
accepting command buffer.
3. Free space check in the AGP buffer is moved to after command
verification, which is more optimal in most cases.
driver. It can now handle the 3D OpenGL commands from the Mesa
unichrome driver.
Added vsync frequency detection support. This will be used in the future
for XvMC and better frame timing.
Bumped minor version number and driver date.
