ciao Stefan,
you can put the monitor on stdio like this: $ qemu-system-x86_64
-monitor stdio ... Then you can interact from your shell and scroll
back up as usual.
thank you, this works perfectly!

Currently, eventfd introduces module_init/module_exit functions
to initialize/cleanup the irqfd workqueue. This only works, however,

Hello everyone,
I am tracing kvm using perf and I am analyzing the sequences of kvm_entry and
kvm_exit tracepoints.
I noticed that during the boot process of a VM, there are a lot more (2 to 3 as
many times) kvm_entry event than there are kvm_exit. I tried looking around but

reviewed last time round this should be ready to commit.
I'm happy to commit via arm-devs.next unless you'd prefer

VFP support (as the TCG Cortex-A15 model always does), since for
