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