Our current CPUID values are based on existing x86 cpus. We'd like to create every cpuid value at runtime. This means that the premade arrays in cpuid.cpp need to be removed and each leaf/subleaf created using values on the host system. This would require creating bitset structs that represent the registers for each leaf/subleaf we support, so instead of doing eg. result.ecx &= ~(1 << 20) we can do result.ecx.sse4_2 = false or similar
Guest environment variables in config.toml and profiles are split using a semicolon. Since environment variables may have semicolons, this is bad design. Toml allows for arrays, so convert to vector. Should make sure environment is properly inherited by child processes.
Search TODO.*Zfa (regex) or 0x3f80 to find values loaded into FPRs with immediates and replace them with the equivalent FLI call.
Our guest VDSO (due to laziness) calls directly into the syscalls, defeating the purpose of VDSO (but also allowing apps that need VDSO to run). Make the VDSO shared library call into the actual VDSO functions, probably through libc. Benchmark performance difference.
Our guest strace (FELIX86_STRACE, FELIX86_STRACE_ERRORS) should allow filtering so that only specific syscalls print. Should also allow to disable certain syscalls. Something similar to what the actual strace binary does with -e trace=...
