Bug#524542: Patches to fix bugs related to TSC clocksource on VMware

2009-07-30 Thread Alok Kataria
I'm not really comfortable applying the tsc-merge patches themselves since its not something I can easily spot check. Is it possible to recode these to apply to the pre-merge tsc files (and demonstrate a low risk of regression)? If so - and someone want to do that, it, then it would

2.6.26 tree, but the tsc merging didn't appear to happen unil 2.6.27-rc1. Specifically, the tsc.c file was introduced here: commit 0ef95533326a7b37d16025af9edc0c18e644b346 Author: Alok Kataria akata...@vmware.com Date: Tue Jul 1 11:43:18 2008 -0700 x86: merge sched_clock handling

fyi, I took a shot at backporting these changes. Unfortunately our source is from before the 32/64 tsc.c merge, and a couple of these patches can't easily apply (even with the intrepid patches). Specifically, these are the changesets I had issues with: commit 83db682 x86: Hypervisor

Package: linux-2.6 Version: 2.6.26-13 This is a bug in the VMI_timer clocksource implementation and affects only when running with VMI enabled on VMware platform. There can be situations when the VMI_CYCLES_COUNTER can go back between subsequent reads of that counter. This could result in kernels

Package: linux-2.6 Version: 2.6.26-13 This is regarding some patches which improve timekeeping for Linux when running under VMware. Without these patches we may see incorrect timekeeping with Debian's lenny kernel when running as guest under VMware. VMware hypervisor exports a consistent TSC to
