Why is that? Couldn’t there be push_simd()/pop_simd() that the syscall itself uses around its SIMD calls? If no syscalls use SIMD today, I’d think we’re starti

If no syscalls use SIMD today, I’d think we’re starting from a safe position.
- durrrrrrrrrrrrr 1y agopush_simd/pop_simd exist and are called kernel_fpu_begin/kernel_fpu_end. Their use is practically prohibited in most areas and iiuc not available on all archs, but it's available if needed.
