Description nicolasm 2003-04-15 20:09:13 UTC

SSE needs to be enabled on Athlon-XP / MP. Kernel 2.4.20 doesn't do this for the
newest kernels, only the earlier versions. This causes problems with mplayer,
which wrongly assumes SSE is present even when it's not, and therefore crashes.
Enabling it & also compiling for athlon-xp in make.conf might gain some speed,
also.

Setup.c patched for Athlon XP detection

Included is file /usr/src/linux-2.4.20-gentoo-r3/arch/i386/kernel/setup.c
patched to recognize latest Athlon-XP core. It's a mere 2 line change, quite
trivial.
