Hey Andi, First let me apologize, I've been busy with other things and its been far too long since I last posted this. Anyway, I found some time to resync my trees and wanted to send this along.
You had asked earlier about performance impact:
Vanilla TSC: 149 nsecs per gtod call 367 nsecs per CLOCK_MONOTONIC call 288 nsecs per CLOCK_REALTIME call Vanilla ACPI PM: 1272 nsecs per gtod call 1335 nsecs per CLOCK_MONOTONIC call 1273 nsecs per CLOCK_REALTIME call
GENERIC_TIME TSC: 149 nsecs per gtod call 304 nsecs per CLOCK_MONOTONIC call 275 nsecs per CLOCK_REALTIME call GENERIC_TIME ACPI PM: 1273 nsecs per gtod call 1275 nsecs per CLOCK_MONOTONIC call 1273 nsecs per CLOCK_REALTIME call
So almost no performance change.
Ingo has a few cleanups I need to merge, but otherwise I think this is getting close to ready for inclusion into -mm for testing. Please let me know if you have any major objections and if not I'll re-diff it against -mm and send it to Andrew.
New in the current C7 release: o Synched up w/ 2.6.19-rc6-git11 o Reworked the patch order to be a bit more logical o Dropped the apic_runs_main_timer removal on Andi's request
Let me know if you have any thoughts or comments!
