[PATCH] xen: fix initialization of wallclock time for PVHVM on migration
The initial values of the wallclock time in the shared info page are set for PVHVM guests when the hypercall page is initialized, since the hypercall page is not reinitialized on resume, the hypervisor wallclock time is not properly set on resume. Fix it by forcing an update of the wallclock values when the shared info page is mapped. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

How to check for proper MSI support?
...vices to disable msi during device initialization by add quirk. So let me get this straight -- you're suggesting I add a quirk for every PCI chipset that doesn't support MSI? There are probably hundreds of these... anything made before 1999 or so, and probably a bunch since then too. There _has_ to be a way to do this generically. Is the PCI spec version anywhere in the root hub? Perhaps we can check if every bridge on the way to the CPU has the MSI capability (including the root hub)? (And naturally _that_ won't work... on my sandybridge laptop, the host bridge doesn't have the M...

[LLVMdev] PassManager Dependence Question
Let's say I have an analysis pass that's dependent on another analysis pass (getAnalysisUsage does the appropraite things). So Pass Y depends on Pass X. If some transformation pass depends on Pass Y and Pass Y has not been invalidated by another other pass BUT Pass X _has_ been invalidated by some other pass, what happens? I can imagine two likely paths in the current implementation of PassManager: 1. Pass Y is not re-run because it is considered up-to-date 2. Pass Y is re-run after Pass X because Pass X is out-of-date Which one of these happens? What I'd r...

The player itself (the silver part) has no fixed storage, so you must have it attached to either the hard drive "backpack" or the smaller Flash component that can be clipped to a belt. -- Greg Wooledge...

filesystem becomming read only
Hi list, I'm looking for advice/help in tracking down a problem with a new system I've purchased. I have a beige box server with a Gigabyte GA-M51GM-S2G motherboard. It has the nVidia MCP51 SATA controller with 3 250 gig Western Digital hard drives attached to it. It seems that when doing a considerable amount of file writing, the filesystem will become read-only. See attached dmesg

[LLVMdev] Hash Table Virtual Calls with Conflict Resolution Stubs
...ing convention for the %method_id argument. Not using %rax for %method_id frees it up for use as %dest, for instance, so using %rdi for %method_id may not actually be a bad idea in practice. If you have to inter-operate with legacy code and are not flexible on how %method_id is propagated (i.e. it _has_ to be in %eax) then a custom calling convention that puts the first argument in %eax is probably the best way to go. > As for forwarding arguments, it seems like the combination of > 'musttail' and varargs come close to satisfying this.

This is somebody's else kickstart password, but I do exclude immediately it as as a result one can imagine a [cyber]criminal action here which I don't expect from anyone ;-) That said, I...
