Subject: freedreno/a6xx: Expand various varying-count bitfields
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=45ec9c0f3de7795c1cb910718749ad828368ca8a;p=mesa.git

freedreno/a6xx: Expand various varying-count bitfields

The extra bit needs to be used when using the maximum of 128 varying
components. I confirmed that PC_PRIMITIVE_CNTL_1 and SP_PRIMITIVE_CNTL
are expanded using a trace of the Vulkan blob with the maximum number of
varyings, and changed the others by analogy.
