2005-08-12Reverting the previous via security-fix commit, since the assumption ofThomas Hellstrom
contexts registered with the callers filp was wrong.
2005-08-10Security fix on via: Checking that the specified context belongs to theThomas Hellstrom
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.
2005-07-15VIA: Fix sparse warnings (Alexey Dobriyan)Thomas Hellstrom
2005-05-23VIA:Thomas Hellstrom
64-bit fixes. Bumped driver date and patchlevel.
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.

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.
2005-02-13Fixed Futex release bug. Bumped driver date and patchlevel.Thomas Hellstrom
2005-02-01cleanup patch from Adrian Bunk <bunk@stusta.de>Dave Airlie
2005-01-05VIA update:Thomas Hellstrom
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.
2004-11-27Reworked PCI MMIO command buffer parser, and imported code from the MesaThomas Hellstrom
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.
2004-10-09cleanup VIA driver to look a bit like others before kernel mergeDave Airlie
2004-10-08Changed unsigned to uint32_t in some ioctl parameters. Introduced firstThomas Hellstrom
rudimentary command verifier for dma buffers. Changed the decoder futex ioctl parameters. Bumped the via major version number.
2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
2004-09-27First check in for DRM that splits core from personality modulesJon Smirl

2004-08-24This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:Erdi Chen
DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH The first ioctl sets up an area in AGP memory that will be used as the ring buffer. The second ioctl copies a command buffer from user space memory to the ring buffer. The third ioctl waits for engine idle until it returns. The motivation for this patch is to avoid the wait for engine idle call before each buffer flush in the current DRI driver. With this patch, the DRI driver can continue to flush its buffer as long as there is free space in the ring buffer. This patch adds an additional copy operation on the command buffer. This buffer copying is necessary to support multiple DRI clients rendering simultaneously. Otherwise, more CPU time will be spent in the busy loop waiting for engine idle between DRI context switch. Even in the single client case, the tradeoff is reasonable in comparision to the kernel call to check for free buffer space for the client to render directly to the ring buffer.

2004-08-14Add a "dev" argument to DRIVER_CTX_[CD]TOR. This will be used in anEric Anholt
upcoming commit for the SiS driver.
