From: Jason Ekstrand Date: Tue, 3 Oct 2017 22:23:07 +0000 (-0700) Subject: anv: Implement vkCmdDispatchBase X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dfe18be09e38c6c534474f3b666a1a57755c7731;p=mesa.git anv: Implement vkCmdDispatchBase This is part of the device groups extension/feature but it's a decent chunk of work in its own right so it's worth breaking into its own patch. The mechanism we use is fairly straightforward: we just push the base work group id into the shader and add it to the work group id we get from dispatch.
