| |
Dear all,
I'm trying to enable ia32 emulation in k1om kernel. Linux kernel is ported for k1om, but with ia32 emulation disabled. With it enabled, I'm getting the following error:
LD arch/x86/crypto/built-in.o AS arch/x86/ia32/ia32entry.o arch/x86/ia32/ia32entry.S: Assembler messages: arch/x86/ia32/ia32entry.S:192: Error: `sysexit' is not supported on `k1om' make[2]: *** [arch/x86/ia32/ia32entry.o] Error 1 make[1]: *** [arch/x86/ia32] Error 2 make: *** [arch/x86] Error 2
sysexit is not supported because k1om (Intel MIC) is essentially Pentium I with AVX512 extensions.
sysexit is used in macro ENABLE_INTERRUPTS_SYSEXIT32, which is in turn used in ENTRY(ia32_sysenter_target).
So, it seems ia32 emulation assumes Pentium II+. Do you see a quick way to make it Pentium I -compatible?
Thanks, - D.
