After reading documentation (and confirming that I already know all the acronyms) and sifting thru driver code I decided to ask on the list, while the people who wrote this stuff can still answer ;)
Basically I want to DMA a chunk of video ram into plain RAM. This is useful for: video capture, VBI/closed captioning, taking screen snapshots. I got drm handle, size of the buffer, AGP offset and pointer to the buffer in XFree86. What can I do with this ? At the moment I am mostly concerned with Radeon AIW AGP, but this will spread to other (non AGP) cards. The docs seem to indicate that both XFree and client can use this - it would be really fabulous if clients could just mmap the buffer. thanks Vladimir Dergachev _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
