From 0346b70083311c65a55038d3e3829da551e229cb Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Thu, 1 Aug 2019 13:30:21 -0700 Subject: [PATCH] gallium/screen: Add pipe_screen::resource_get_param This function retrieves individual parameters selected by enum pipe_resource_param. It can be used as a more direct alternative to pipe_screen::resource_get_handle.
