From: Eric Anholt Date: Thu, 2 Oct 2014 00:32:50 +0000 (-0700) Subject: vc4: Add #defines for the texture uniform fields. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5c72d7706c55d2832b816af4192afa010de51636;p=mesa.git vc4: Add #defines for the texture uniform fields. I wanted to make another set of texture uploads for handling reladdr constants, and duplicating all the bitshifting looked like a terrible idea. In the process, this fixes a swap of the s/t texture wrap modes. --- diff --git a/src/gallium/drivers/vc4/vc4_packet.h b/src/gallium/drivers/vc4/vc4_packet.h index a8b3566c5c6..e9abfd17314 100644 --- a/src/gallium/drivers/vc4/vc4_packet.h +++ b/src/gallium/drivers/vc4/vc4_packet.h @@ -81,6 +81,18 @@ enum vc4_packet { VC4_PACKET_GEM_HANDLES = 254, } __attribute__ ((__packed__));
