- Dmalcolm 18:02, 15 June 2009 (UTC) If a Fedora user wants to verify that a CPU will work with F12, how should he/she query /proc/cpuinfo ? (and does smolt have any of this data?) Thanks
- Bill Nottingham Once a set has been decided on, this should be pretty trivial. With respect to the proposal, 'grep sse2 /proc/cpuinfo' should work.
- Bruno: Is there a way to tell which binaries actually use SSE2 instructions so that a secondary arch targeting athlons would be able to inherit safe binaries from the i686+ arch?
- Neal Gompa: Pentium II and lower do not support SSE or SSE2. Pentium III only supports SSE, not SSE2. Pentium 4 supports SSE2 and SSE3. However, all Pentium chips (Pentium Pro and higher) support i686 + MMX. If we wanted to move to i686, a secondary arch offering no SSE2 would be a good idea.
