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.
2004-07-29initial port of i915 to BSD, not finished doesn't work.. no idea why...Dave Airlie
2004-05-09Add mach64 DRM module for BSD (untested, but compiles).Eric Anholt
2004-05-09- Link in shared files as necessary and clean them up.Eric Anholt
- Generate drm_pciids.h automatically.
2003-08-29Port the SiS DRM to FreeBSD. This includes the ability for the DRM toEric Anholt
allocate framebuffer memory without sisfb, and a new ioctl to be used by the X Server which tells the DRM what region of framebuffer memory to allocate from. Also fixes a possibility to panic the kernel I believe. Tested on linux with sisfb and FreeBSD (without sisfb) with new DRI only.
2003-08-19- Remove $FreeBSD$ tags as they weren't too useful and merges are now beingEric Anholt
done through perforce. - Add copyright headers to drm_os_*bsd.h, still need to research the other copyright-less files better.
