In the l4linux-2.6, if set L4ARCH=arm, the processor type is fixed to CPU_SA1100. And the arm instruction version is armv4.

I want to use arch-dependent code for pxa, so I changed CPU_SA1100 to CPU_XSCALE config and arm instruction set version to armv5te at --------------------------------------------------- $ l4linux-2.6/arch/l4/Makefile

CFLAGS += -D__LINUX_ARM_ARCH__=5 -march=armv5te

This is perfectly ok, I guess.

---------------------------------------------------

and found a code,

--------------------------------------------------- $ l4linux-2.6/arch/l4/kernel/arch-arm/setup.c

unsigned int processor_id = 0x0001f000; /* ARMv4 */ ---------------------------------------------------

The processor_id is fixed to ARMv4 value. My question is

001. How processor_id affect the linux?? Should I also change this value to a armv5te value??

It should not harm to change this to some ARMv5 type.

002. If I have to change it, what is the proper value for armv5te?? I can't find the value anywhere.

A quick look at the code in setup.c suggests 5f000 but I could be wrong. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
