Revision as of 23:40, 23 June 2009
This page collects a list of projects to improve the infrastructure of coreboot-v2. Infrastructure means those parts of the code that aren't chipset or mainboard specific, but are used by all of them.
The idea is to consolidate a list of things "to do" with their status and responsible developers.
In progress
CBFS
A filesystem-alike layout for the coreboot image, to enable systems like bayou and to clean up the system in general (eg. no more buildrom)
Status
Upstream, implemented on some boards. Known problems on some boards.
Developers
Stefan, Ron, Patrick, Myles
Low/High Tables
SeaBIOS requires a copy of various BIOS tables outside the fseg as it overwrites that segment. Generally clean out the table generation code.
Status
Upstream, implemented on some boards. Problems on others.
Developers
?
Port v3 Resource Allocator
The v3 resource allocator should be ported to v2
Status
Patches exist.
Developers
Myles
More ideas
Locking
There is some locking infrastructure in printk_*, but there are many copies of that code, with their own locking or none at all. Unification of that would fix hard to decipherable garbage on serial.
Unify ACPI
Every ACPI board has its own routines to compile the ACPI sources. Unify that. Also, figure out generic ACPI code and deduplicate it
Build System
The current system of generated Makefiles is non-ideal (for too many reasons for this little margin). Fix it, somehow
Config System
Use KConfig (or something else) that improves on the current situation.
Unify fallback/normal switch
Right now, the decision whether to use fallback or normal is in cache_as_ram_auto.c in many boards. Make that generic again (also helps with further CBFSification at some point).
Common payload location
Many boards in v2 have different names for the payload in targets/.../Config.lb (payload.elf, filo.elf, etherboot.elf, etc) and locations (../payload.elf, or various absolute paths which only work for one developer). We should fix this by using ../payload.elf as common payload name/location for all boards. A long-term solution will probably be the use of Kconfig in v2 where the user specifies a payload manually as in v3.
