Subject: radv: fix compute pipeline keys when optimizations are disabled
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9ab27647ff5379e8095a70c23dd16792f074c8c7;p=mesa.git

radv: fix compute pipeline keys when optimizations are disabled

If an app first creates a compute pipeline with
VK_PIPELINE_CREATE_DISABLE_OPTIMIZATION_BIT set, then re-compile it
without that flag, the driver should re-compile the compute shader.
Otherwise, it will return the unoptimized one.

Fixes: ce188813bfe ("radv: add initial support for VK_PIPELINE_CREATE_DISABLE_OPTIMIZATION_BIT")
