Subject: [PATCH 16/21] vulkan: Define new VK_MESA_query_timestamp extension
Date: Tue, 13 Feb 2018 16:31:29 -0800	[thread overview]
Message-ID: <20180214003134.1552-17-keithp@keithp.com> (raw)
In-Reply-To: <20180214003134.1552-1-keithp@keithp.com>

This extension adds a single function to query the current GPU
timestamp, just like glGetInteger64v(GL_TIMESTAMP, &timestamp). This
function is needed to complete the implementation of
GOOGLE_display_timing, which needs to be able to coorelate GPU and CPU
timestamps.
