2011-06-29powerpc/rtas-rtc: remove sideeffects of printk_ratelimitChristian Dietrich1-12/+17
Don't use printk_ratelimit() as an additional condition for returning on an error. Because when the ratelimit is reached, printk_ratelimit will return 0 and e.g. in rtas_get_boot_time won't check for an error condition.

2006-06-09[PATCH] powerpc: reorg RTAS delay codeJohn Rose1-14/+16
This patch attempts to handle RTAS "busy" return codes in a more simple and consistent manner. Typical callers of RTAS shouldn't have to manage wait times and delay calls. This patch also changes the kernel to use msleep() rather than udelay() when a runtime delay is necessary. This will avoid CPU soft lockups for extended delay conditions.

2006-03-16[PATCH] powerpc: RTC memory corruptionMichael Neuling1-1/+1
We should be memset'ing the data we are pointing to, not the pointer itself. This is in an error path so we probably don't hit it much. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-18powerpc: time-of-day fixes for 32-bit CHRP systemsPaul Mackerras1-3/+3
This makes 32-bit CHRP systems use the RTAS time-of-day routines if available. It fixes a bug in the RTAS time-of-day routines where they were storing a 64-bit timebase value in an unsigned long by making those variables u64. Also, the direct-access time-of-day routines had the wrong convention for the month and year in the struct rtc_time. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-14[PATCH] powerpc: kill ppc64 rtc.c, use genrtc insteadBenjamin Herrenschmidt1-0/+105
This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel, and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate of the genrtc functionality. Also enable build of genrtc for CONFIG_PPC64 (it just works are we already have the required callbacks) and enable it in all defconfigs.
