I'm getting a teensy Cyrix detection thinglet introduced in 2.1.120
In 2.1.119 and below (Except a few versions when that whole thing was re-written a while back) /proc/cpuinfo looks like:
processor : 0 vendor_id : CyrixInstead cpu family : 5 model : 6x86L model name : 6x86L 2x Core/Bus Clock stepping : 4.2 fdiv_bug : no hlt_bug : no sep_bug : no f00f_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de cx8 bogomips : 149.50
Which is all correct, it's a 6x86L PR200+ (no MX) running at 150MHz (2x 75MHz)
I just spent the evening backing out patches and compiling and 2.1.119 is definetly good, and 2.1.120, pre-2.1.121-1, and "real" 2.1.121 do this:
processor : 0 vendor_id : CyrixInstead cpu family : 5 model : 49 model name : 6x86L 2x Core/Bus Clock stepping : 4.2 fdiv_bug : no hlt_bug : no sep_bug : no f00f_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de cx8 bogomips : 119.60
The boot messages are normal in all cases (not counting the bogomips, which matches the /proc/cpuinfo): ... Linux version 2.1.121 (root@toolz) (gcc version 2.8.1) #9 Fri Sep 11 22:39:22 EDT 1998 Console: colour VGA+ 80x25 Calibrating delay loop... 119.60 BogoMIPS Memory: 63180k/65536k available (856k kernel code, 404k reserved, 1052k data, 44k init) Checking if this processor honours the WP bit even in supervisor mode... Ok. CPU: Cyrix 6x86L 2x Core/Bus Clock stepping 4.2 Checking 386/387 coupling... OK, FPU using exception 16 error reporting. Checking 'hlt' instruction... OK. ...
uname also looks normal:
/ext/src/linux-2.1.121 # uname -a Linux toolz 2.1.121 #9 Fri Sep 11 22:39:22 EDT 1998 i586 CyrixInstead
No "real" symptoms noticed. All the compiles went fine, X and pppd seem normal.
All test compiles were gcc 2.8.1 -O2 -m486 on a RedHat 5.0 system.
ALthough I *am* currently running 2.1.121 compiled with gcc-2.8.1 -O9 -mpentium on redhat 5.0 and pgcc -09 -mpentium on Stampede (AMDk6233, cpuinfo unnoticed untill monday) so far so good. ( I know it's silly, and any extra "snappiness" is probably all in my head. I'm allowed. :) )
