Raw Normal View History

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!

Use rtc_lock to protect RTC operations Many RTC routines were not protected against each other, so there are potential races, for example, ntp-update against /dev/rtc. This patch fixes them using rtc_lock. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

[MIPS] Handle R4000/R4400 mfc0 from count register. The R4000 and R4400 have an errata where if the cp0 count register is read in the exact moment when it matches the compare register no interrupt will be generated. This bug may be triggered if the cp0 count register is being used as clocksource and the compare interrupt as clockevent. So a simple workaround is to avoid using the compare for both facilities on the affected CPUs. This is different from the workaround suggested in the old errata documents; at some opportunity probably the official version should be implemented and tested. Another thing to find out is which processor versions exactly are affected. I only have errata documents upto R4400 V3.0 available so for the moment the code treats all R4000 and R4400 as broken. This is potencially a problem for some machines that have no other decent clocksource available; this workaround will cause them to fall back to another clocksource, worst case the "jiffies" source.

[MIPS] Only build r4k clocksource for systems that work ok with it. In particular as-is it's not suited for multicore and mutiprocessors systems where there is on guarantee that the counter are synchronized or running from the same clock at all.
