Yes. Actually clipboard-itis. > The scratch register values need to be read with DRM_READ32(), which > accounts both for endianness and memory barriers.

I thought the card took care of that when it wrote the value back (I believe it can) but maybe not. Falling back to the INREG() call if the ioctl returns EINVAL seems like a wise move. I'm still poking at that lockup (tracing the packet contents now). I'm juggling working on it with other things as we have a houseguest at the moment so the spare room where the computers live is occupied during prime "hacking hours". If I don't have anything better by the weekend I'll post a patch containing my "I don't properly understand why this works" fix on Friday (going to be v. busy all weekend). -- Tim Smith ([EMAIL PROTECTED]) Ce n'est pas une .sig ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Oh, it's good to be a geek. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
