Stamp softlockup thread earlier before do_timer, because the latter is the one to actually trigger lock warning for long-time offline. Or else, I obserevd softlockup warning easily at manual vcpu hot-remove/plug, or when suspend cancel into old context. One point here is to cover both stolen and blocked time to compare with offline threshold. v...

Hello, I am trying to compile 134.perl - the spec95 benchmark using LLVM and I am getting the following error message - -------------------------------------------- 34.perl/symbol/dolist.c:1786: warning: "struct tm" declared inside parameter list 134.perl/symbol/dolist.c:1786: warning: its scope is only this definition or declaration, which is probably not what you want

The following patches are the latest update of the TSC and hrtimer patches I posted on 29/03. Rusty's original TSC patch has been resynced to the latest lguest repo, as has the hrtimer patch, which also incorporates feedback from Jeremy & Rusty: - Change clock event hrtimer to absolute time. 'now' is captured in the host during the hypercall. - Propagate -ETIME back to the

As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of
