Title:
Set MIPS MSA in ELF Auxiliary Vectors
Status in QEMU:
In Progress
Bug description:
The MIPS MSA feature is currently not set in the ELF auxiliary vector.
That is, querying the AT_HWCAP key of the ELF auxiliary vectors for a
MIPS CPU that has the MSA feature should return a value that has the
second bit [0] set.
From [0], `HWCAP_MIPS_MSA` is defined to `1 << 1`.
