For details development history on these boards, refer to the git log
|
||
|
|
and documentation.
|
||
|
|
|
||
|
|
For boards previously supported, many fixes from upstream have been
|
||
|
|
merged.
|
||
|
|
|
||
|
|
Other changes (compared to libreboot 20150518), for libreboot in general
|
||
|
|
or for previously supported systems: (this is a summary. For more
|
||
|
|
detailed change list, refer to the git log)
|
||
|
|
|
||
|
|
256MiB VRAM allocated on GM45 (X200, T400, T500, R400) instead of 32MiB.
|
||
|
|
This is an improvement over both Lenovo BIOS and Libreboot 20150518,
|
||
|
|
allowing video decoding at 1080p to be smoother. (thanks Arthur Heymans)
|
||
|
|
To clarify, GM45 video performance in libreboot 20160818 is better than
|
||
|
|
on the original BIOS and the previous libreboot release.
|
||
|
|
|
||
|
|
64MiB VRAM on i945 (X60, T60, MacBook2,1) now supported in
|
||
|
|
coreboot-libre, and used by default (in the previous release, it was
|
||
|
|
8MiB allocated). Thanks to Arthur Heymans.
|
||
|
|
|
||
|
|
Higher battery life on GM45 (X200, T400, T500, R400) due to higher
|
||
|
|
cstates now being supported (thanks Arthur Heymans). C4 power states
|
||
|
|
also supported.
|
||
|
|
|
||
|
|
Higher battery life on i945 (X60, T60, MacBook2,1) due to better CPU
|
||
|
|
C-state settings. (Deep C4, Dynamic L2 shrinking, C2E).
|
||
|
|
|
||
|
|
Text mode on GM45 (X200, T400, T500, R400) now works, making it possible
|
||
|
|
to use MemTest86+ comfortably. (thanks to Nick High from coreboot)
|
||
|
|
|
||
|
|
Dual channel LVDS displays on GM45 (T400, T500) are now automatically
|
||
|
|
detected in coreboot-libre. (thanks Vladimir Serbinenko from coreboot)
|
||
|
|
|
||
|
|
Partial fix in coreboot-libre for GRUB display on GM45, for dual channel
|
||
|
|
LVDS higher resolution LCD panels (T400, T500). (thanks Arthur Heymans)
|
||
|
|
|
||
|
|
Massively improved GRUB configuration, making it easier to boot more
|
||
|
|
encrypted systems automatically, and generally a more useful menu for
|
||
|
|
booting the system (thanks go to Klemens Nanni of the autoboot project).
|
||
|
|
Libreboot now uses the grub.cfg provided by the installed GNU+Linux
|
||
|
|
distribution automatically, if present, switching to that configuration.
|
||
|
|
This is done across many partitions, where libreboot actively searches
|
||
|
|
for a configuration file (also on LVM volumes and encrypted volumes).
|
||
|
|
This should make libreboot more easy to use for non-technical users,
|
||
|
|
without having to modify the GRUB configuration used in libreboot.
|
||
|
|
|
||
|
|
Utilities archives is now source only. You will need to compile the
|
||
|
|
packages in there (build scripts included, and a script for installing
|
||
|
|
build dependencies). (binary utility archives are planned again in the
|
||
|
|
next release, when the new build system is merged)
|
||
|
|
|
||
|
|
SeaGRUB is now the default payload on all x86 boards. (SeaBIOS
|
||
|
|
configured to load a compressed GRUB payload from CBFS immediately,
|
||
|
|
without providing an interface in SeaBIOS. This way, GRUB is still used
|
||
|
|
but now BIOS services are available, so you get the best of both
|
||
|
|
worlds). Thanks go to Timothy Pearson of coreboot for this idea.
|
||
|
|
|
||
|
|
crossgcc is now downloaded and built as a separate module to
|
||
|
|
coreboot-libre, with a universal revision used to build all boards.
|
||
|
|
|
||
|
|
Individual boards now have their own coreboot revision and patches,
|
||
|
|
independently of each other board. This makes maintenance easier.
|
||
|
|
|
||
|
|
Updated all utilities, and modules (coreboot, GRUB, etc) to newer
|
||
|
|
versions, with various bugfixes and improvements upstream.
|
||
|
|
|
||
|
|
RTC century byte issue now fixed on GM45 in coreboot-libre, so the date
|
||
|
|
should now be correctly displayed when running the latest linux kernel,
|
||
|
|
instead of seeing 1970-01-01 when you boot (thanks to Alexander Couzens
|
||
|
|
from coreboot)
|
||
|
|
|
||
|
|
Build system now uses multiple CPU cores when building, speeding up
|
||
|
|
building for some people. Manually specifying how many cores are needed
|
||
|
|
is also possible, for those using the build system in a chroot
|
||
|
|
environment. (thanks go to Timothy Pearson from coreboot)
|
||
|
|
|
||
|
|
In the build system (git repository), https:// is now used when cloning
|
||
|
|
coreboot. http:// is used as a fallback for GRUB, if git:// fails.
|
||
|
|
|
||
|
|
New payload, the depthcharge bootloader (free bootloader maintained by
|
||
|
|
Google) for use on the ASUS Chromebook C201. (thanks go to Paul
|
||
|
|
Kocialkowski)
|
||
|
|
|
||
|
|
Various fixes to the ich9gen utility (e.g. flash component density is
|
||
|
|
now set correctly in the descriptor, gbe-less descriptors now supported)
|
||
|
|
|
