No, though it cuts out VIA C3 (used mostly(?) on EPIA (mini-ITX) boards). I have one but it had never run Fedora (only PXE ramdisk-based small LFS). Hmm... Just checked and it seems they still list EPIA-M and others as "available". I'm not sure what to think about that: - The CPU in question is C3 Eden / Samuel 2 / Ezra (not sure about the difference but C3-2(?) aka Nehemiah seems to be CMOV-capable). - I think the clock range is 400 - 1000 MHz, though I've only seen 600+ MHz versions. - it seems they've started selling mini-ITX EPIAs in 2002 - low-power fanless boards, the old EPIA-M was capable of hardware decoding MPEG2 and I'm told newer boards can do MPEG4 in hardware as well - they are/were popular as DVD/digital TV/DVR boxes. - Eden CPU datasheet dated Jan 18, 2006 states that "CMOV and FCMOV instructions available" and "Notes On CPUID Feature Flags: The CMPXCHG8B instruction is provided and always enabled, however, it can be disabled in the corresponding CPUID function bit 8 to avoid a bug in an early version of Windows NT. However, this default can be changed via bit 1 in the FCR MSR." - Maybe Samuel 2 and Ezra are non-cmov and Eden is cmov-able? I don't say if those CPUs have to be supported by Fedora, I'm just posting this for completeness. -- Krzysztof Halasa -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
