Hello,
I've run into what appears to be a dead-lock while running tessellation demo by David Blythe which is included in the Glut-3.7 source distribution (glut-3.7/progs/advanced/tes.c) I've been able to reproduce the problem on two different Intel Pentium III SMP machines (550, 850) both using radeon 64mb DDR cards. And I've been able to reproduce it in both the mesa-3-5 and mesa-4-0 branches. While running the demo the machine immediately locks up -- I'm unable to regain control of the X server at all and need to reboot. It appears that the radeon driver obtains a hardware lock and just never releases it for some reason(?) It does this while emitting triangle strip vertices. As a work-around I've disable triangle strips by setting HAVE_TRI_STRIPS to 0 in radeon_render.c, and this works but it's not much of a solution. Has anyone else encountered the problem? Any possible pointers?/solutions? Any help (especially in the form of a nice little patch that fixes the problem) would be greatly apreciated... Thanx, jOrGe W. _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
