1. No longer allocate a miptree structure for hiz on gen7+. 2. Always enable hiz for depth on gen8+.
3. Enable hiz Auxiliary Buffer support on gen8. This support allows Broadwell to sample from depth using the hiz buffer, and thereby removing the need to resolve depth to/from the hiz buffer in many cases. v2: * Modified hz_height calculation in patches 4 & 5 Patches without Reviewed-by: 4, 5, 6, 13 and 14 This series is available in the bdw-aux-hiz-v2 branch of: git://people.freedesktop.org/~jljusten/mesa Jordan Justen (13): i965/hiz: Start to separate miptree out from hiz buffers i965/gen7: Don't rely directly on the hiz miptree structure i965/gen8: Don't rely directly on the hiz miptree structure i965/gen7: Don't allocate hiz miptree structure i965/gen8: Don't allocate hiz miptree structure i965/gen8: Enable hiz for all depth levels i965: Wrap MCS miptree in intel_miptree_aux_buffer i965/gen8: Use intel_miptree_aux_buffer for auxiliary buffer i965/gen8: Use aux buf qpitch for Auxiliary Buffer (MCS) i965: Add function to indicate when sampling with hiz is supported i965: Support sampling with hiz during rendering i965/gen8: Initialize aux_mode to GEN8_SURFACE_AUX_MODE_NONE i965/gen8: Allow sampling with hiz when supported Kenneth Graunke (1): i965/gen8: Add HiZ auxiliary buffer support src/mesa/drivers/dri/i965/brw_blorp_clear.cpp | 2 +- src/mesa/drivers/dri/i965/brw_draw.c | 5 +- src/mesa/drivers/dri/i965/brw_misc_state.c | 4 +- src/mesa/drivers/dri/i965/gen6_blorp.cpp | 2 +- src/mesa/drivers/dri/i965/gen7_blorp.cpp | 10 +- src/mesa/drivers/dri/i965/gen7_misc_state.c | 7 +- src/mesa/drivers/dri/i965/gen7_wm_surface_state.c | 8 +- src/mesa/drivers/dri/i965/gen8_depth_state.c | 6 +- src/mesa/drivers/dri/i965/gen8_surface_state.c | 45 +-- src/mesa/drivers/dri/i965/intel_fbo.c | 4 +- src/mesa/drivers/dri/i965/intel_mipmap_tree.c | 363 ++++++++++++++++++---- src/mesa/drivers/dri/i965/intel_mipmap_tree.h | 41 ++- 12 files changed, 394 insertions(+), 103 deletions(-) -- 2.0.1 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
