Hi,
I tried the patch-2.6.13-rt12 on mvme2100 board, I made the following
changes to get it pass compiling:
(no CONFIG_HIGH_RES_TIMER)
1) mv include/asm-ppc/hrtime.h include/asm-ppc/hrtimer.h
2) in arch/ppc/syslib/todc_time.c, add :
unsigned long cpu_khz;
3)in include/linux/time.h, add :
+#ifndef div_long_long_rem
+#define div_long_long_rem(dividend,divisor,remainder) \
+({ \
+ u64 result = dividend; \
+ *remainder = do_div(result,divisor); \
+ result; \
+})
+#endif
+
When booting, it stoped after displaying:
...
openpic :enter
I remove two printk statement after the output "openpic :enter" in
arch/ppc/syslib/open_pic.c.
and then boot and display the following:
....

What else have to be changed to make it booting? By the way, Linux2.6.13
can boot when not applying the
patch-2.6.13-rt12.
please cc any answer/comments to my email.
thanks in advance for any help.
