I'm writing an OS in Rust and require APIC support. When I boot my kernel with qemu-system-x86_64, however, it dumps out a [lot] of warnings; it claims that TCG doesn't support FMA, X2APIC, AVX, F16C, AVX2, RDSEED, SHA-NI, FXSR-OPT, misalignsse, 3dnowprefetch, osvw, topoext, perfctr-core, clzero, xsaveerptr, ibpb, nrip-save, xsavec, and xsaves, but prints these warnings over 80 times before finally doing what I told it to do.
