From: Ben Widawsky Date: Tue, 14 Jul 2015 16:56:09 +0000 (-0700) Subject: i965: Push miptree tiling request into flags X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=51e8d549e110f86cb7107cf712843aebd956fb9a;p=mesa.git i965: Push miptree tiling request into flags With the last few patches a way was provided to influence lower layer miptree layout and allocation decisions via flags (replacing bools). For simplicity, I chose not to touch the tiling requests because the change was slightly less mechanical than replacing the bools. The goal is to organize the code so we can continue to add new parameters and tiling types while minimizing risk to the existing code, and not having to constantly add new function parameters. v2: Rebased on Anuj's recent Yf/Ys changes Fix non-msrt MCS allocation (was only happening in gen8 case before) v3: small fix in assertion requested by Chad Signed-off-by: Ben Widawsky Reviewed-by: Jordan Justen (v2) Reviewed-by: Anuj Phogat (v2) Reviewed-by: Chad Versace (v2) --- diff --git a/src/mesa/drivers/dri/i965/brw_tex_layout.c b/src/mesa/drivers/dri/i965/brw_tex_layout.c index 389834f012a..a12b4af579e 100644 --- a/src/mesa/drivers/dri/i965/brw_tex_layout.c +++ b/src/mesa/drivers/dri/i965/brw_tex_layout.c @@ -614,8 +614,8 @@ brw_miptree_layout_texture_3d(struct brw_context *brw, */ static uint32_t brw_miptree_choose_tiling(struct brw_context *brw, - enum intel_miptree_tiling_mode requested, - const struct intel_mipmap_tree *mt) + const struct intel_mipmap_tree *mt, + uint32_t layout_flags) { if (mt->format == MESA_FORMAT_S_UINT8) { /* The stencil buffer is W tiled.
