Hi,
I made my attempt to port ADM5120 stuff from the prehistoric 2.4.18 kernel to recent 2.4.27-mipscvs. I get to boot, but:
time.c originally uses: extern unsigned int mips_counter_frequency; from timex.h
but in 2.4.27 the timex.h changed to: extern unsigned int mips_hpt_frequency;
Jeroen uses just a localy defined mips_counter_frequency in his 2.6.x port.
Using jeroens time.c the system boots painfully slow, sort of loops int the beginning and the finally freezes on the FPU emulator... any suggestions ?
Thanks Tom
