From a36b7dcc05bc4c4580f11cf78e95edfefa86b8a6 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Mon, 21 Apr 2008 16:27:24 +1000 Subject: [PATCH] drm/i965: On I965, use correct 3DSTATE_DRAWING_RECTANGLE command in vblank The batchbuffer submission paths were fixed to use the 965-specific command, but the vblank tasklet was not. When the older version is sent, the 965 will lock up.
