powerpc: Move a bunch of ppc64 headers to include/asm-powerpc ... and also delete some that are no longer used because we already had an include/asm-powerpc version of the header. Signed-off-by: Paul Mackerras <paulus@samba.org> 2005-11-14 17:22:01 +11:00

[PATCH] powerpc: sanitize header files for user space includes include/asm-ppc/ had #ifdef __KERNEL__ in all header files that are not meant for use by user space, include/asm-powerpc does not have this yet. This patch gets us a lot closer there. There are a few cases where I was not sure, so I left them out. I have verified that no CONFIG_* symbols are used outside of __KERNEL__ any more and that there are no obvious compile errors when including any of the headers in user space libraries.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 15:20:36 -07:00












powerpc: Fix delay functions for 601 processors My earlier merge of delay.h introduced a timebase-based udelay for 32-bit machines but also broke the 601, which doesn't have the timebase register. This fixes it by using the 601's RTC register on the 601, and also moves __delay() and udelay() to be out-of-line in arch/powerpc/kernel/time.c. These functions aren't really performance critical, after all. Signed-off-by: Paul Mackerras <paulus@samba.org> 2005-11-18 13:44:17 +11:00

[POWERPC] Fix mdelay badness on shared processor partitions On partitioned PPC64 systems where a partition is given 1/10 of a processor, we have seen mdelay() delaying for 10 times longer than it should. The reason is that the generic mdelay(n) does n delays of 1 millisecond each. However, with 1/10 of a processor, we only get a one-millisecond timeslice every 10ms. Thus each 1 millisecond delay loop ends up taking 10ms elapsed time. The solution is just to use the PPC64 udelay function, which uses the timebase to ensure that the delay is based on elapsed time rather than how much processing time the partition has been given. (Yes, the generic mdelay uses the PPC64 udelay, but the problem is that the start time gets reset every millisecond, and each time it gets reset we lose another 9ms.)
