RE: [PATCH] remove bogus ppc_select syscall

I have tested the provided patch on PPC32 with little modifications. Test passed on the PPC32. Modification to Arnd's Patch: In systbl.h you have changed -SYSX(sys_ni_syscall,sys_ni_syscall,ppc_select) +SYSCALL(sys_ni_syscall) That has to be

nanosleep() and hrtimer on PPC64

hi, all, Does anyone know why nanosleep system call does not use kernel high resolution timer on 2.6.21 (PPC64)? This makes user space nanosleep() almost un-usable. thanks rick ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org ht

How do I access nvRAM from user space?

Sorry for the dumb question, I just can figure out the right google search to find what I'm trying to do. I'm running 2.6.27-rc4 on an mpc8347 with a 32KiB nvSRAM (Cypress CY14B256L) on the local bus. We just want to be able to access this memory from user space seperately from "main" memory.

Re: How do I access nvRAM from user space?

Hi Bruce, You can use mmap to access NVRAM from user space, but you should config local bus first, like width, speed etc. Regards, Yanjun Luo. 发件人： [EMAIL PROTECTED] 发送时间： 2008-09-25 11:44:56 收件人： linuxppc-embedded@ozlabs.org 抄送： 主题： How do I access nvRAM from user space? Sorry for th
