libreboot!
this is forked from the "libre" branch in osboot, which is itself a libre, deblobbed fork of osboot, a blobbed up fork of libreboot libreboot needed to be purged clean. this is the new libreboot development repository. the old one has been abandoned

Subject: [PATCH 2/6] Allow loading Option ROM (so we can use graphics cards)
|
||||
|
||||
Since 49d99fcebc7c3860def51812c2f723ad3e8a4ea3 Option ROMs can't be loaded
|
||||
PCI graphics cards anymore when "Graphics initialization" is set to "Use
|
||||
native graphics init". This means only onboard graphics can be used until
|
||||
the OS or SeaBIOS initialise PCI graphics cards.
|
||||
This patch allows us to do a little hack. We can set "Use native graphics
|
||||
init" to "Run VGA Option ROMs" and activate "Load Option ROMs on PCI
|
||||
devices". This way coreboot will load the Option ROM on PCI graphics cards
|
||||
which means payloads like GRUB can display graphics.
|
||||
There's only one catch: onboard graphics won't work anymore. Because of this
|
||||
we'll include seavgabios.bin (compiled by SeaBIOS) in CBFS. This will give
|
||||
us the option to use both PCI graphics cards and onboard graphics that work
|
||||
with native graphics init.

Subject: [PATCH 3/6] Tweak cmos defaults for KCMA-D8 (for a little speed
|
||||
boost)
|
||||
|
||||
63xx CPUs have the option to use a reduced latency value inside the crossbar.
|
||||
Setting "experimental_memory_speed_boost=Enable" aparently only has an effect
|
||||
on 63xx CPUs and may, in certain cases, yield a slight memory bandwidth
|
||||
increase (according to Timothy Pearson), but maybe it also works for
|
||||
43xx CPUs.
|
||||
|
||||
Setting "l3_cache_partitioning=Enable" will increase performance in certain
|
||||
situations. See:
|
||||
https://developer.arm.com/documentation/100453/0401/functional-description/l3-cache/l3-cache-partitioning?lang=en

Subject: [PATCH 4/6] Do not use microcode updates on AMD platforms
|
||||
|
||||
Coreboot is hardcoding the use of microcode updates on some platforms.
|
||||
|
||||
Just nuke it from orbit. This is the libre branch of osboot, so microcode must
|
||||
not be used.
