libpayload: Support curses for serial
by Jordan Crouse 21 Jun '08

21 Jun '08

Support curses over serial. Tested with coreinfo over qemu, looks good. I'm not sure what will happen when we actually get in front of a real terminal emulator, but thats part of the fun. Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc.

Bayou v0.3
by Jordan Crouse 20 Jun '08

20 Jun '08

Greetings. I am very happy to present to you the next version of the proof-of-concept for Bayou, the Coreboot payload chooser. A good amount of this version was re-written to support everybody's favorite feature: chaining! :) Let me get the usual URLS out the way. Source and QEMU demo: http://www.coreboot.org/~jcrouse/bayou_0.3.tar.gz http://www.coreboot.org/~jcrouse/bayou-demo-20080619.rom The default chain runs a password checker and then coreinfo. If you press escape before the timeout, you can run coreinfo directly from the menu, or run the default chain. If you exit from coreinfo in the chain, you will go back to the menu automatically. The "system password" is 'coreboot'. My apologies to Uwe - I know he has a better password payload, but he is busy right now, and I needed to hack something together really quickly. oh, and make sure you check it all out in serial too.. :) This is using the configuration scheme that I wrote up on the Bayou wiki page: http://www.coreboot.org/Bayou The bayou_payload_table format allows us to support chains, menu items, and menu items that turn into chains; basically the whole shooting match. The downside is that this makes building the LAR somewhat more complex. To help with that, I wrote a new utility I call pbuilder that uses an XML file to define the payloads to be included and writes the LAR and automatically inserts the payloads it needs. I chose XML because it fit well with the nested nature of the configuration table. Time will tell if it will work well with buildrom or not. I'll be documenting all of this on the wiki in the coming days. So there you go. Comments welcome. Our next step after this is to start resolving the various SELF related feuds and start getting this code checked in.
