HVM firmware passthrough - helper library

HVM firmware passthrough - helper library

[Ross Philipson]

[-- Attachment #1: Type: text/plain, Size: 508 bytes --]

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.

Would it make sense / are you planning to integrate this into the Xen
tree as well? I'm not sure if it fits into an existing library e.g.
libxenguest if it would be a separate library.

Right so I mainly put it out there because some people asked for it. 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.

Thanks
Ross

Following up on this. Is there any interest in integrating this into
xen? 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

Maybe the best place would be in libxl itself, or perhaps better in
libxlu?

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.

Art,

Can you try the attached tarball. A colleague found and fixed a couple
of issues in my sample including the face that it was including in the
wrong Rules.mk.

Ross,

I rebuilt Xen 4.2.1 with the V5 patch series and the updated helper library. The biospt utility built cleanly and runs on Dom0 with the aformentioned libraries in place. However, I'm not seeing the SMBIOS strings passed through to the DomU (A Centos 5 VM). Options 1 and 3 using the biostpt utility appear to dump the SMBIOS and ACPI tables, but I'm not sure how to pass the tables in to the VM?

[root@localhost biospt]# ./biospt 
Usage:
$ biospt <n>
 1 - Write some SMBIOS tables using MMAP
 2 - Write some SMBIOS tables using SYSFS
 3 - Write some ACPI tables using MMAP
 4 - Write some ACPI using SYSFS
 5 - Read and trace DMI files
 6 - Write out some test files

./biospt 6
Make SMBIOS file from FW.
Fail(1), errno: 2

Art

Look at the related commits to libxl. After the firmware chunks are 
given to libxc to load into the new domain, the addresses are returned 
to libxl which writes them to xenstore.

This is a rather rough test app for using the library. You should look 
closely at the code in it and figure out what it is doing. It does not 
have very robust error handling etc.

Re: HVM firmware passthrough - helper library

[-- Attachment #1.1: Type: text/plain, Size: 4847 bytes --]

Works great with the updated libxl commits - thanks.  

> ./biospt 6
> Make SMBIOS file from FW.
> Fail(1), errno: 2

Looks like this does require the sysfs-dmi kmod to expose the dmi structure for the utility to write out the smbios_fw.bin. 


# ./biospt 6
Make SMBIOS file from FW.
Make SMBIOS Xen vendor struct.
Wrote SMBIOS structures file: smbios_fw.bin count: 8
Make ACPI SLIC file from FW.
Fail(3), errno: 2


Do the ACPI tables require the same exposure via sysfs? Not sure if this 
changes from 2.6 to 3.x kernels. The biospt utility can dump the ACPI 
tables using the MMAP option, but not via sysfs on a 3.4.32 system. 



Thanks,
Art

They are in the same place on my wheezy with 3.2.x kernel. I would be

Re: HVM firmware passthrough - helper library

[Art Napor]

[-- Attachment #1.1: Type: text/plain, Size: 10402 bytes --]

Could the biospt utility generate the ACPI table file even on systems without OEM/branding tables - /SLIC? I have a kludgy work around to mount overtop of /sys/firmware/acpi/tables/SLIC before running the utility for systems without, but was wondering if the utility could skip over SLIC for systems that don't have this table.

Right well there is nothing that mandates it be there. It is an OEM 
platform license.

The utility can do whatever you want it to do - is really is just sample 
code. I wrote it to test the code I was submitting and I just happened 
to pick the SLIC table to snarf. Please feel free to modify it in any 
way you see fit, the library itself lets you specify what tables you 
want to grab.

Ross,

Did this make it into 4.3? I was going to try it on the 4.2.3 with the latest patches.

Hello Art, Ross,

The patch[es] mentioned here are to facilitate exposing BIOS SLICs to
an HVM, right?  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!

Cheers,
Andrew Bobulsky
