Author: Francisco Jerez <[email protected]> Date: Thu Sep 3 17:08:16 2015 +0300 i965: Keep track of whether LRI is allowed in the context struct. This stores the result of can_do_pipelined_register_writes() in the context struct so we can find out later whether LRI can be used to program the L3 configuration. v2: * Split change of gen check in can_do_pipelined_register_writes (jljusten) Reviewed-by: Jordan Justen <[email protected]> Reviewed-by: Kristian Høgsberg <[email protected]> --- src/mesa/drivers/dri/i965/brw_context.h | 5 +++++ src/mesa/drivers/dri/i965/intel_extensions.c | 4 +++- 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/brw_context.h b/src/mesa/drivers/dri/i965/brw_context.h index abc6d56..2fee6a7 100644 --- a/src/mesa/drivers/dri/i965/brw_context.h +++ b/src/mesa/drivers/dri/i965/brw_context.h @@ -866,6 +866,11 @@ struct brw_context bool use_resource_streamer; /** + * Whether LRI can be used to write register values from the batch buffer. + */ + bool can_do_pipelined_register_writes; + + /** * Some versions of Gen hardware don't do centroid interpolation correctly * on unlit pixels, causing incorrect values for derivatives near triangle * edges.
