2005-08-15Port the VIA DRM to FreeBSD. Original patch by Jake, with some cleanup byEric Anholt
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. Submitted by: Jake Burkholder <jake@FreeBSD.org> Tested by: unichrome
2005-07-15VIA: Fix sparse warnings (Alexey Dobriyan)Thomas Hellstrom
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.
2005-03-14via changes:Thomas Hellstrom
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.
2004-12-13VIA drm updates:Thomas Hellstrom
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.
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.
2004-10-09Lindent the via stuff so I can include it in kernelDave 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
2004-09-07Added IOCTL for writing 2D DMA command buffers over PCI. Bumped minorThomas Hellstrom
version number.
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.
2004-04-121. Added a PCI ID.Thomas Hellstrom
2. Big change to the XvMC part of the SAREA. OpenGL clients will not suffer from this, and via XvMC is still alpha. Needed to make future additions to XvMC (More decoders and overlays) possible. 3. Bumped version number to 1.3.0.
