From 9dadfc09a9dd492f14eec8de060d3f5198c766ec Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sun, 2 Nov 2008 18:49:33 -0800 Subject: i965: Fix up SF max_threads. We were dividing the number of URB entries by two to get number of threads, which looks suspiciously like a copy'n'paste-o from brw_vs_state.c. Also, the maximum number of threads is 24, not 12. --- src/mesa/drivers/dri/i965/brw_sf_state.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i965/brw_sf_state.c b/src/mesa/drivers/dri/i965/brw_sf_state.c index 4f925d1810..506126fcfb 100644 --- a/src/mesa/drivers/dri/i965/brw_sf_state.c +++ b/src/mesa/drivers/dri/i965/brw_sf_state.c @@ -172,7 +172,8 @@ sf_unit_create_from_key(struct brw_context *brw, struct brw_sf_unit_key *key, sf.thread4.nr_urb_entries = key->nr_urb_entries; sf.thread4.urb_entry_allocation_size = key->sfsize - 1; - sf.thread4.max_threads = MIN2(12, key->nr_urb_entries / 2) - 1; + /* Each SF thread produces 1 PUE, and there can be up to 24 threads */ + sf.thread4.max_threads = MIN2(24, key->nr_urb_entries) - 1; if (INTEL_DEBUG & DEBUG_SINGLE_THREAD) sf.thread4.max_threads = 0; -- cgit v1.2.3
