Fixes: Bug 26686 - Some textures are distorted with libdrm 2.4.18 in GTAVC>A3 http://bugs.freedesktop.org/show_bug.cgi?id=26686 This bug continues to haunt me. The kernel SET_TILING ioctl is inconsistent in its return values when reporting an error. If one of its sanity checks fail, then the input values are left unchanged. If the kernel later fails to change the tiling mode, then the input values are modified to match the current tiling on the object. In short, userspace cannot trust the return values upon error and so we must assume that upon error our current tiling mode matches reality and not update. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
