search for: trace_var

For my debugging pleasure I have added another domctrl to call trace_var from xc_save. That works as expected. However, it adds additional pressure on the tracebuffer because each hypercall is traced as well. My question is: Would an additional domctrl (or whatever), or another trace hypercall be acceptable? Another hypercall would at least have a chance to be ignored...

Address some credit2 issues. This patch series, along with the recent changes to the cpupools interface, should address some of the strange credit2 instability. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, This small series deals with some weirdness in the mechanism with which the credit scheduler choses what PCPU to tickle upon a VCPU wake-up. Details are available in the changelog of the first patch. The new approach has been extensively benchmarked and proved itself either beneficial or harmless. That means it does not introduce any significant amount of overhead and/or performances
