Hi,first of all: Thanks a lot for putting effort into this sort of ancient hardware, I'm really surprised in a very positive way to see open source UVD support happen on old R600 GPUs. I gave the recently posted patches a shot an here is my first impression:
Kernel from uvd-r600-release branch compiles and boots fine(I also included the 3.16.1 and Con Kolivas' ck/BFS patch as well, I hope that was OK; I could give it a try without modifications as well, if that would help.)
Mesa with the posted patch applied also compiled fine First tests with mplayer were not so successful, unfortunately: I tried "big buck bunny" with both software and hardwarde decoding.Software looks OK (as expected). Hardware decoding seems to work, mplayer doesn't complain and CPU usage also goes down significantly, the resulting image is distorted, however. I tried to get a screen shots to illustrate the issue, see attachment. Looks like part of the top is found at the bottom, and look sort of like an interlaced image.
This test was done on an RS780 / HD3200 desktop chipset. Maybe this helps you? Best regards, Stefan P.S.: some more info:dmesg shows that the UVD block is initialized as expected (after one error message before, however, don't know if that's expected or not):
[ 4.275315] [drm:uvd_v1_0_start] *ERROR* UVD not responding, trying to reset the VCPU!!!
[ 4.295533] [drm] UVD initialized successfully. vdpauinfo output also looks good to me: display: :0 screen: 0 API version: 1 Information string: G3DVL VDPAU Driver Shared Library version 1.0 Video surface: name width height types ------------------------------------------- 420 8192 8192 NV12 YV12 422 8192 8192 UYVY YUYV 444 8192 8192 Y8U8V8A8 V8U8Y8A8 Decoder capabilities: name level macbs width height ------------------------------------------- MPEG1 0 9216 2048 1152 MPEG2_SIMPLE 3 9216 2048 1152 MPEG2_MAIN 3 9216 2048 1152 H264_BASELINE 41 9216 2048 1152 H264_MAIN 41 9216 2048 1152 H264_HIGH 41 9216 2048 1152 VC1_ADVANCED 4 9216 2048 1152 Output surface: name width height nat types ---------------------------------------------------- B8G8R8A8 8192 8192 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 R8G8B8A8 8192 8192 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 R10G10B10A2 8192 8192 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 B10G10R10A2 8192 8192 y NV12 YV12 UYVY YUYV Y8U8V8A8 V8U8Y8A8 Bitmap surface: name width height ------------------------------ B8G8R8A8 8192 8192 R8G8B8A8 8192 8192 R10G10B10A2 8192 8192 B10G10R10A2 8192 8192 A8 8192 8192 Video mixer: feature name sup ------------------------------------ DEINTERLACE_TEMPORAL y DEINTERLACE_TEMPORAL_SPATIAL - INVERSE_TELECINE - NOISE_REDUCTION y SHARPNESS y LUMA_KEY - HIGH QUALITY SCALING - L1 - HIGH QUALITY SCALING - L2 - HIGH QUALITY SCALING - L3 - HIGH QUALITY SCALING - L4 - HIGH QUALITY SCALING - L5 - HIGH QUALITY SCALING - L6 - HIGH QUALITY SCALING - L7 - HIGH QUALITY SCALING - L8 - HIGH QUALITY SCALING - L9 - parameter name sup min max ----------------------------------------------------- VIDEO_SURFACE_WIDTH y 48 2048 VIDEO_SURFACE_HEIGHT y 48 1152 CHROMA_TYPE y LAYERS y 0 4 attribute name sup min max ----------------------------------------------------- BACKGROUND_COLOR y CSC_MATRIX y NOISE_REDUCTION_LEVEL y 0.00 1.00 SHARPNESS_LEVEL y -1.00 1.00 LUMA_KEY_MIN_LUMA y LUMA_KEY_MAX_LUMA y
