Attached is a tarball with a helper library for reading host ACPI and SMBIOS firmware and creating firmware files that can be used with the HVM firmware passthrough patches I submitted. I used it in my testing of the patches and planned to use it later when we moved to a new Xen version. This library was requested by a few people - I hope you find it useful.

I had the same issue while I was working on the fw patches - I could not really figure out where it might belong. That is why I left it separate and did not submit it for inclusion (though I had mentioned it in some earlier threads). I am perfectly happy to have it integrated in Xen (and submit patches for it) if we can figure out how and where to integrate it.

I don't think it belongs in xenguest because it would be used up at the libxl level where the fw blobs are passed in via the xl config file. It seems like it should be in some separate utilities library but I can't really see where. Thanks Ross ^ permalink raw reply [flat|nested] 18+ messages in thread

Toolstacks are supposed to be moving towards using libxl(u) anyway and even in the interim linking against the library for just these functions is no great hardship.

Ok, yeah. I was looking at libxlu on Friday. I just wasn't really sure what the intended scope of that library was. But the routines in that helper library to snarf firmware bits are pretty much utility functions. I can try knocking something together in libxlu and submit it.

I was curious about doing this some time back but never got far enough along to try it. Being able to expose a SLIC through a config file option would be a very slick way to shim Xen in between Windows and system firmware on a VT-d capable laptop, among other things. Just adding in my two cents to show some desire for the feature!
