[tboot-devel] Enhance serial support in tboot

[Ross P. <Ros...@ci...>]

I have recently been working on laptops that do not have serial ports so
I have been using an ExpressCard serial adapter. I had to make
modification to tboot to use a different IO port and clock frequency. I
have found that having serial debug output for tboot is incredibly
valuable during development.

 

The Xen console driver (on which the tboot early_printk is loosely based
as it seems) allows serial console configuration with command line
arguments (including setting the clock freq. now). I was thinking of
pulling this into tboot but I wanted to see if the community thought
this was something valuable to do - something that could be incorporated
in tboot?

 

Thanks

Ross
