Build 64bit on RaQ2
Subsystems (2)
Has anyone had any luck compiling a 64 bit version on the RaQ2. I can
get it to compile but, it locks up during boot up.
elf64: 00080000 - 0042fd3f (ffffffff,803e6000) (ffffffff,8000000)
elf64: ffffffff,80080000 (8008000) 3731589t + 134331t
That's all I got during bootup, no error messages or anything.

Peter Horton had some experimental code in the kernel at one point to try this. I managed to get a 2.6.9 (I think, maybe 2.6.10) mips64 kernel to boot on cobalt, but it was pretty useless. Poor machine was slower than molasses uphill in winter.
I believe cobalt would run better using the o64 kernel hack than pure n64 kernel (-mabi=64), but cobalt needs some fixups to its spaces.h before an o64 kernel will build on it.

As a starting point you need to ensure the "cpu_has_llsc" is false for 64-bit Cobalt kernels. LLD/SCD is broken on RM5230/5231. There is an experimental patch for 2.6.9 on
http://www.colonel-panic.org/cobalt-mips.

Peter,
Got it to compile, but the tulip driver is giving me fits. I built
it as a module and into the kernel

Tulip driver gave me problems also. I landed up inserting a printk() which made it work, see the patch. I didn't get round to debugging it any further, sorry.

I posted a simliar question to the linux-net list, a lot of people don't understand why the driver doesn't work in 64 bit, but works perfectly in 32 bit.

Peter here is the fix for the linux-mips version of kernel and the tulip driver. Thanx again for you help
