Hi,
I played with it yesterday.
I have x11perf lockups too. And X sometimes crash (simply exits) to
login screen. I use FC3 and then when I do ctrl+alt+F1 (to get to
console) system freezes (few uppers rows are redrawn (maybe by console
text)), but no switch to text mode.
When I uncomment these rows - then x11perf works (and no more X
crash), but 3D locks as expexted:
In radeon_cp.c in function radeon_do_cp_idle
if (IS_FAMILY_R300(dev_priv)) {
BEGIN_RING( 4 );
OUT_RING_REG(R300_RB3D_DSTCACHE_CTLSTAT, 0x00000002);
OUT_RING_REG(0x4F18, 0x00000001); /* Z cache? */
ADVANCE_RING();
}
and in radeon_stat.c in function radeon_cp_dispatch_swap:
if (IS_FAMILY_R300(dev_priv)) {
/* Make sure the new caches are flushed */
radeon_do_cp_idle(dev_priv);
} else {
BEGIN_RING(2);
RADEON_WAIT_UNTIL_3D_IDLE();
ADVANCE_RING();
}
changed to
BEGIN_RING(2);
RADEON_WAIT_UNTIL_3D_IDLE();
ADVANCE_RING();
