 Hi here,

 are there any Pegasos users using Gentoo?

 Especially the hardware platform Pegasos II?

 I am looking for experiences about building an own kernel for this
 architecture. I compile them by myself for some years, but I think I could
 be better if I find someone else who is building kernels for Pegasos
 II. I am interested to exchange/talk about config files and so on.

 Unfortunately Gentoo seems to have dropped kernel support for Pegasos
 for some years. No installation disk contains a kernel for this
 hardware.



Hi Johannes,

I'm not a Pegasos user, but if you can get other Linux distribution running
on your system (e.g., some old version of Debian), you will be able to 
build Gentoo from its environment.

[gentoo-ppc-user] -mabi=altivec in CFLAGS

[Konstantin Tokarev]

Hi all,

AFAIK, some packages (e.g., dev-cpp/eigen) can use AltiVec vectorization
only when -mabi=altivec is specified in GCC flags.

Is it safe to use -mabi=altivec in global CFLAGS in make.conf?
Does anybody know if the system will perform better or worse in average?
