From: Caio Marcelo de Oliveira Filho Date: Tue, 7 May 2019 06:46:42 +0000 (-0700) Subject: anv: Remove special allocation for anv_push_constants X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f7d53fffa22d2620bb32cc3c6d9e6b8278ee8272;p=mesa.git anv: Remove special allocation for anv_push_constants The key reason for that mechanism is gone: all the extra optional data that could be in the anv_push_constants was moved elsewhere. At this point, just put anv_push_constants directly in anv_cmd_state (part of anv_cmd_buffer). v2: Remove a NULL check we don't need anymore in anv_cmd_buffer_push_constants(). (Lionel) Fix size we consider for valid push params.
