Further cleanup of the hv drivers: 1) Cleanup the reference counting mess for both stor and net devices. 2) Handle all block devices using the storvsc driver. 3) Accomodate some host side scsi emulation bugs. 4) In case of scsi errors off-line the device. Regads, K. Y

Here's my current greedy solution: 1) For each vreg, calculate how many MutatingFMA instructions are using them, and put the result into ref_count. Set up a worklist that's holding all MutatingFMA instructions. 2) Try to get a MutatingFMA from worklist, as MI, such that, it has at least one operand %x that has ref_count 1. If we can't find one, go to 4). 3) Make a suggestion about MI and %x. Remove MI from active set and decrease the...

Further cleanup of the hv drivers. Back in June I had sent two patch sets to address these issues. I have addressed the comments I got from the community on my earlier patches here: 1) Implement code for autoloading the vmbus drivers without using PCI or DMI signatures. I have implemented this based on Greg's feedback on my earlier implementation. 2) Cleanup error handling across

I'm creating a structure type which has a variable component. I'm not clear on the correct way to ensure the alignment of the variable part is correct and how to get the offset. For example, I have a wrapping structure format that looks like this: struct wrap: int32 ref_count PointerType(FunctionType) func_ptr T data Where 'T' is the desired extra data. I need to ensure that T is always at the same offset in this structure (thus I can't simply create a structure with all the elements). T will be used opaquely (a pointer passed to func_ptr as the first par...

Were you suggesting the following? 1) get a free page block from the page list using the API; 2) if page->ref_count == 0, send it to the hypervisor Btw, ref_count may also change at any time. > Is there any > documentation which describes the workflow or code which would use your > new API? > It's used in the balloon driver (patch 8).
