From f3ecc90730c1637b82e7a8eb8bef6d9a7a0531e8 Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Tue, 23 Aug 2011 11:43:46 -0700 Subject: [PATCH] i965: new VS: Compute urb entry size based on the VUE map. Previously, the new VS backend computed the size of the URB entry by counting the number of MRFs used in emitting the URB entry. Now it just gets it straight from the VUE map.
