Subject: radeonsi: load fmask ptr relative to the resources array
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7d5162bdc0850c80f4b9427a2aac6b42c7dcceaa;p=mesa.git

radeonsi: load fmask ptr relative to the resources array

res_ptr already contains the resource values. fmask_ptr needs to be
looked up relative to the start of the resource params.

Note that this only affects indirect loads of MS sampler arrays.
