[PATCH 3/4] viafb: make suspend and resume work (on all machines?)
viafb: make suspend and resume work (on all machines?) This patch removes the dangerous suspend and resume code that was developed for VX855 only. After this the framebuffer is expected to cause no longer serious (freezing) issues on any machines. However the hardware acceleration is broken now so only doing resu... 26 Apr 2010 14:55
[PATCH 2/6] Add a global synchronization point for pvclock
In recent stress tests, it was found that pvclock-based systems could seriously warp in smp systems. Using ingo's time-warp-test.c, I could trigger a scenario as bad as 1.5mi warps a minute in some systems. (to be fair, it wasn't that bad in most of them). Investigating further, I found out that such warps were cau... 26 Apr 2010 14:55
[PATCH 5/6] Try using new kvm clock msrs
We now added a new set of clock-related msrs in replacement of the old ones. In theory, we could just try to use them and get a return value indicating they do not exist, due to our use of kvm_write_msr_save. However, kvm clock registration happens very early, and if we ever try to write to a non-existant MSR, we... 26 Apr 2010 14:55

[PATCH 4/6] export new cpuid KVM_CAP
Since we're changing the msrs kvmclock uses, we have to communicate that to the guest, through cpuid. We can add a new KVM_CAP to the hypervisor, and then patch userspace to recognize it. And if we ever add a new cpuid bit in the future, we have to do that again, which create some complexity and delay in feature ... 26 Apr 2010 14:55
[PATCH 1/6] Enable pvclock flags in vcpu_time_info structure
This patch removes one padding byte and transform it into a flags field. New versions of guests using pvclock will query these flags upon each read. Flags, however, will only be interpreted when the guest decides to. It uses the pvclock_valid_flags function to signal that a specific set of flags should be taken ... 26 Apr 2010 14:55
