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!

[PATCH] x86_64: Switch SMP bootup over to new CPU hotplug state machine This will allow hotplug CPU in the future and in general cleans up a lot of crufty code. It also should plug some races that the old hackish way introduces. Remove one old race workaround in NMI watchdog setup that is not needed anymore. I removed the old total sum of bogomips reporting code. The brag value of BogoMips has been greatly devalued in the last years on the open market. Real CPU hotplug will need some more work, but the infrastructure for it is there now. One drawback: the new TSC sync algorithm is less accurate than before. The old way of zeroing TSCs is too intrusive to do later. Instead the TSC of the BP is duplicated now, which is less accurate. akpm: - sync_tsc_bp_init seems to have the sense of `init' inverted. - SPIN_LOCK_UNLOCKED is deprecated - use DEFINE_SPINLOCK.

[PATCH] x86_64: Add pmtimer support There are unfortunately more and more multi processor Opteron systems which don't have HPET timer support in the southbridge. This covers in particular Nvidia and VIA chipsets. They also don't guarantee that the TSCs are synchronized between CPUs; and especially with MP powernow the systems are nearly unusable because the time gets very inconsistent between CPUs. The timer code for x86-64 was originally written under the assumption that we could fall back to the HPET timer on such systems. But this doesn't work there. Another alternative is to use the ACPI PM timer as primary time source. This patch does that. The kernel only uses PM timer when there is no other choice because it has some disadvantages. Ported over from i386. It should be faster than the i386 version because I dropped the "read three times" workaround, but is still considerable slower than HPET and also does not work together with vsyscalls which have to be disabled.
