Hello,all I applied linux 2.6.21 and Ingo's patch 2.6.21-rt1 on ppc8260, It can't be complied successfully when I used ARCH=ppc, and the patch can work when using ARCH=powerpc. When using powerpc, the maximum latency of interrupt and preemption are all increased, about 5ms, regardless patch was applied or not. Does the rt patch not fit ppc, or I used it incorrect? Thanks.
