These are new hwcap bits added for power10. Signed-off-by: Joel Stanley <j...@jms.id.au> --- MMA support for TCG is on the list so I think it makes sense for this to land after those are merged.
I tested my patch with this program: https://github.com/shenki/p10_tests $ qemu-ppc64le -cpu power10 -L ~/ppc64le/ ./test -c HWCAP: 0x58000580 HWCAP2: 0x8ee60000 ISAv3.1: Yes MMA: Yes $ qemu-ppc64le -cpu power9 -L ~/ppc64le/ ./test -c HWCAP: 0x58000580 HWCAP2: 0x8ee00000 ISAv3.1: No MMA: No linux-user/elfload.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/linux-user/elfload.c b/linux-user/elfload.c index 61063fd974e5..0908692e62b3 100644 --- a/linux-user/elfload.c +++ b/linux-user/elfload.c @@ -779,6 +779,8 @@ enum { QEMU_PPC_FEATURE2_DARN = 0x00200000, /* darn random number insn */ QEMU_PPC_FEATURE2_SCV = 0x00100000, /* scv syscall */ QEMU_PPC_FEATURE2_HTM_NO_SUSPEND = 0x00080000, /* TM w/o suspended state */ + QEMU_PPC_FEATURE2_ARCH_3_1 = 0x00040000, /* ISA 3.1 */ + QEMU_PPC_FEATURE2_MMA = 0x00020000, /* Matrix-Multiply Assist */ }; #define ELF_HWCAP get_elf_hwcap() @@ -836,6 +838,8 @@ static uint32_t get_elf_hwcap2(void) QEMU_PPC_FEATURE2_VEC_CRYPTO); GET_FEATURE2(PPC2_ISA300, QEMU_PPC_FEATURE2_ARCH_3_00 | QEMU_PPC_FEATURE2_DARN | QEMU_PPC_FEATURE2_HAS_IEEE128); + GET_FEATURE2(PPC2_ISA310, QEMU_PPC_FEATURE2_ARCH_3_1 | + QEMU_PPC_FEATURE2_MMA); #undef GET_FEATURE #undef GET_FEATURE2 -- 2.35.1
