[GSOC] Panic Room, week #7

What have you procrastinated on this past week?

As usual, I’m glad you asked.

During the past week I worked every day(/night) on the porting of the region_device API (commit) as I probably mentioned last week. The port is now complete and it should be bug-free (?).
It’s been tested pretty thoroughly since I immediately used it to adapt Bayou from the old LAR/coreboot-v3 paradigm to the new CBFS/coreboot-v4 one.
A bunch of bugs cropped up with the new API during the transition (debugging the API wasn’t fun at all) but they have been solved and unless for some corner-cases that I missed it should just work.

The second part of the week, as you might have guessed read, has been devoted to fixing Bayou (commit). This has been quite fun, almost everything was broken or relied on some old function that has since been dropped from libpayload.
It now works quite well and supports all of the original features.
The only problem now are with the other payloads since they aren’t all able to exit cleanly and give back control to bayou (i.e. coreinfo reboots before returning, tint halts, etc).
If you want to know more details take a look at the commit message.

Apart from this two items I wrote a couple of patches concerned with libpayload and a patch that adds support for sequential lz4 decompression during the boot process (Thank you, Julius Werner, for pointing that out).
I also just finished updating the wiki entry for Bayou, so if someone wants to test it out… 🙂

What’s next?

With less than a month left of my GSOC time I plan to dedicate solely to maintain the patches that I currently have and work on the coreboot/serialice integration (so as to finally do something pertinent to the original proposal).

Have a nice weekend!



I had to drop the idea of working on the FILO (flashupdate) project since it relies on a series of patches that have not been finished yet (libflashrom). It will be a project for another time perhaps.


I think I lost count of a few weeks here and there…
