From: Kenneth Graunke Date: Fri, 28 Dec 2012 20:45:14 +0000 (-0800) Subject: i965: Replace structs with bit-shifting for Gen7 SURFACE_STATE entries. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82f8e8ebd57720f1e9d148c7dc65b14c218307df;p=mesa.git i965: Replace structs with bit-shifting for Gen7 SURFACE_STATE entries. Every generation except Gen7 creates SURFACE_STATE entries via a uint32_t array. Only Gen7 uses the older bitfield structure, which we moved away from because it was less efficient. Convert it for consistency. This reduces the compiled size of gen7_wm_surface_state.o by 2.86% in a release build. v2: Fix accidental use of BRW_SURFACE_WIDTH/HEIGHT in brw_state_dump.c; switch back to gen7_set_surface_mcs_info setting surf[6] directly (both per Eric's review comments).
