Looking at SiFive U74 manuals, shouldn't this be RV64GC_Zba_Zbb_Sscofpmf?
U74 only supports Zba and Zbb bit manip extensions.
This is from the 21G3.02.00 release manual.
Looking more, S76 core is listed in the manual as supporting up to:
RV64IMAC_Zicsr_Zifencei_Zba_Zbb_Sscofpmf.
I almost forgot about _Zicsr_Zifencei (which are part of G). Shouldn't
those be listed too in riscv,isa?
