Thus spake Damian Gerow (damian@sentex.net) [02/06/03 16:48]: > So, in order to use & compile on the Via C3 Ezra, I need to set CPUTYPE=i586 > or CPUTYPE=i586/mmx (both seem to work) in /etc/make.conf, and I need at > least I686_CPU in my kernel configuration file. Seems odd to me, but at > least it works. I have since found out that this might be because the compiler enables support for the CMOV instruction if CPUTYPE=i686, whereas the C3 does /not/ support CMOV (well, this core doesn't, anyhow). Running the kernel as an i686 kernel works just fine, but compiling it doesn't. I've verified that using 5.1-RC1 results in the same problem.
