Subject: [PATCH 0/5][time][x86_64] GENERIC_TIME patchset for x86_64
Date: Tue, 28 Nov 2006 22:00:18 -0500 [thread overview]
Message-ID: <20061129025728.15379.50707.sendpatchset@localhost> (raw)
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!
thanks again!
-john
