The Ipipe patch for ARM only support the integrator platform for
now. There exist patch for another ARM platform, but it exist only as
a separated patch. Looking at the patch contents it seems that the only
patched files specific to the integrator architecture are :
arch/arm/mach-integrator/core.c
arch/arm/mach-integrator/integrator_cp.c
include/asm-arm/arch-integrator/entry-macro.S
include/asm-arm/arch-integrator/platform.h
include/asm-arm/arch-integrator/timex.h
Looking rapidly at these files, it seems that the machine specific
functions and variables are reduced to:
int __ipipe_mach_timerint;
int __ipipe_mach_timerstolen;
unsigned int __ipipe_mach_ticks_per_jiffy;
void __ipipe_mach_acktimer(void);
unsigned long long __ipipe_mach_get_tsc(void);
void __ipipe_mach_set_dec(unsigned long reload);
unsigned long __ipipe_mach_get_dec(void);
If you provide the same variables and functions for the PXA platform, I
think there is no modification to be done at Xenomai level.
