These chipsets include the VP2 engine which is composed of a bitstream processor (BSP) that decodes H.264 and a video processor (VP) which can do iDCT/mo-comp/etc for MPEG1/2, H.264, and VC-1. Both of these are driven by separate xtensa chips embedded in the hardware. This patch provides the mechanism to load the kernel for the xtensa chips and provide the necessary interactions to do the rest of the work. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> --- v1 -> v2: - factored out similar logic between vp and bsp into a new xtensa.c, similar to falcon - moved firmware loading to init rather than ctor (kinda wonder what happens if you suspend while playing a video... hmm.) - created new "blank" copies of vp/bsp for nv98+, identical to the old nv84 ones, but s/84/98/g At this point I have H.264 and MPEG1/2 working fairly well. Back when there were bugs in my mesa code, VP would freeze up sometimes and the watchdog would fire. I have no idea how to actually reset the engine though... so it's just a notification for now. These would happen when buffers were incorrectly sized, wrong addresses were passed in, etc. Also it's worth pointing out that the blob firmware being used allows arbitrary xtensa code to be uploaded by a user (with dri access), which in turn could enable that code to have all the system memory access that the card has (e.g. no iommu). It's a giant security hole, but without rewriting the firmware, there's not a whole lot that can be done. In any case, the kernel driver isn't affected.
