[coreboot] [SerialICE] [ANNOUNCE] libhwremote 0.1

[Idwer Vollering]

2012/3/10 Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006 at gmx.net>:
> I'm glad to announce libhwremote 0.1, a library which forwards hardware
> accesses over a serial line to a machine running SerialICE. No QEMU needed!
> All you have to do to run lspci/superiotool/... against a remote
> SerialICE target is to compile those tools against libhwremote, and then
> just run them like you would run them natively.
>
> libhwremote is an early prototype. Due to that it has quite a few quirks:
> - Each run of a libhwremote enabled application requires the application
> to be started before SerialICE prints its banner, i.e. start the
> application, then hit reset on the SerialICE target. The reason is the
> init code which expects "newline,serialice_banner,newline" to do
> anything useful. If that banner is not there, the results are undefined.
> - The error handling is mostly working but not really nice.
> - /dev/ttyUSB0 is hardcoded for serial line access, you may want to
> change that.
> - MMIO functions are totally untested, I didn't find any code which
> needed it (except for flashrom, but probing for flash chips might
> interfere with SerialICE functionality if SerialICE runs from ROM).
> - The pciutils patch is totally untested, but I expect it to work.
>
> A big THANK YOU goes to Idwer Vollering who tested a dozen iterations of
> this code until I had figured out the very surprising and unique
> properties of the SerialICE protocol.
>
> Another big THANK YOU goes to Ron Minnich who sent a mail titled
> "[SerialICE] an idea" which motivated me to start this little project:
> http://serialice.com/pipermail/serialice/2009-November/000043.html
>
> This code sat unfinished on my disk since December 2009, and it's about
> time I finished it enough to be usable.
>
> Notes::
> - superiotool support is tested and stable
> - pciutils (lspci/setpci/...) support is untested, but should work.
>
> Please fetch latest superiotool from the coreboot git tree and latest
> pciutils from the pciutils git tree to apply the patches.
