[PATCH v4 0/6] 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 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.

Supersedes: <20201201192807.1094919-1-f4bug@amsat.org>

Philippe Mathieu-Daudé (6):
  linux-user/elfload: Move GET_FEATURE macro out of get_elf_hwcap() body
  linux-user/elfload: Rename MIPS GET_FEATURE() as GET_FEATURE_INSN()
  linux-user/elfload: Introduce MIPS GET_FEATURE_REG_SET() macro
  linux-user/elfload: Introduce MIPS GET_FEATURE_REG_EQU() macro
  linux-user/elfload: Update HWCAP bits from linux 5.7
  linux-user: Add support for MIPS Loongson 2F/3A
