[PATCH v5 0/7] linux-user: Rework get_elf_hwcap() and support MIPS Loongson 2F/3A
Posted by Philippe Mathieu-Daudé 4 years, 11 months ago
Series now fully reviewed.

Since v4:
- Fixed yet another typo...

Since v3:
- Add CP0C0_AR_LENGTH definition (Richard)
- Fixed 3E -> 3A, Longsoon -> Loongson typos (Huacai)

Since v2:
- Use extract32() in GET_FEATURE_REG_EQU (rth)

Introduce the GET_FEATURE_REG_SET() and GET_FEATURE_REG_EQU()
macros to check if an instruction set is supported by a CPU
using CP0 read-only bits (instead of QEMU insn_flags which
is not always coherent - we might remove it soon).

Use these macros to test for MSA ASE and Release 6.

Update the ELF HWCAP bits and set the Loongson instructions
so we can run 2F/3A userland binaries.
