Hi all,
I'm trying to get my Kodi media center working but am experiencing crashes when playing a movie. There is a ticket at https://bugs.freedesktop.org/show_bug.cgi?id=27512. From the help I've received so far and the research I've done it sounds like the instruction prefetch is not available on Pentium 4. That's what produces the original error:
Program terminated with signal SIGILL, Illegal instruction. #0 _mesa_x86_64_transform_points4_general () at x86-64/xform4.S:72 72 prefetch 16(%rdx) [Current thread is 1 (Thread 0x7f9054aeb9c0 (LWP 791))]
I've tried the suggested patch which updates src/mesa/x86-64/xform4.S to use prefetcht1 instead of prefetch. I understand that prefetcht1 is part of SSE which Pentium 4 supports. It worked for a few days but now I'm getting this error:
Program terminated with signal SIGILL, Illegal instruction. #0 _mesa_x86_64_transform_points4_general () at x86-64/xform4.S:72 72 prefetcht1 16(%rdx) [Current thread is 1 (Thread 0x7fd24af779c0 (LWP 797))]
Is the prefetcht1 instruction supported by Pentium 4? Any suggestions about an alternative instruction I could try?
Thanks, Mike
