This changes Heads' bootscript for the x230 to gui-init and adds config
options needed for it. The config is very similar to the librem13v2 config.
My comparison of startup-time from a power-button press shows 2.5 seconds
more with these changes applied.
That said, the experience is smooth, the GUI is beautiful and easier to use
than the shell and text menu, especially during setup. That's what we
buy with startup time here.
The Librem coreboot is labeled with the current version and is visible
from dmidecode and is supposed to reflect the current version of
coreboot, however it was out of date and reflected 4.7 when Heads has
moved on to 4.8.1.
I've also added a simple change to further simplify onboarding by
warning users who have Librem Key configured when they boot without it
being inserted.
This reduces the amount of noise in the Linux kernel config files
by only storing the differences from the stock configuration.
It adds a new makefile target 'linux.saveconfig' to convert the
build tree's .config file into config/linux-linuxboot.config.
Adding the VBT file makes it available through some ACPI memory area
and apparently the VBT contains the information needed by the i915 driver
in order to figure out how to control the screen's backlight.
Without the VBT, we can't control the screen backlight with Fn-F5/Fn-F6
anymore.
Fixes access to the EC through the Index I/O interface
Fixes AC and DC LoadLine values to avoid overheating problems
Fix Turbo mode value from EC
Change version name to have '-heads' suffix
By enabling Pass-through iommu, it fixes the GPU glitching issues
we've had with IOMMU, and it also allows us to boot a target kernel
without having to give it intel_iommu=igfx_off as argument.
Guarded linuxboot specific init entries
Removed Makefile entries into separate file (conflicts with srcing /etc/config)
Added CONFIG_BOOT_LOCAL/_REMOTE to control interface setup
Fixed CONFIG_TPM usage
USB smart card readers are most full speed devices, and there is no
"rate-matching hubs" beneath the root hub on older (e.g. GM45) plat-
forms, which has companion OHCI or UHCI controllers and needs cor-
responding drivers to communicate with card readers directly plugged
into the motherboard, otherwise a discrete USB hub should be inserted
between the motherboard and the reader.
This time I make inserting linux modules for OHCI and UHCI controllable
with option CONFIG_LINUX_USB_COMPANION_CONTROLLER.
A linux config for x200 is added as an example.
Tested on my x200s and elitebook revolve 810g1.
Move board configuration into `boards/` instead of `config/`
Fix mistake in building kernel module tree before kernel was done.
Allow per-board initrd builds (#278)
Allow per-board configurations for things (#304)
This modifies the `Makefile.nerf` to create files based on the
$(BOARD) variable, which is necessary as we start to support
multiple mainboards.
The config files must define five variables, all in bytes:
* `NERF_SIZE` - for the EFI firmware volume that contains Linux
* `PEI_SIZE` - size of the PEI image in the vendor ROM
* `PEI_OFFSET` - offset of the PEI image in the vendor ROM
* `ME_SIZE` - size of the ME image in the vendor ROM, or 0 if
there is no ME image to be extracted.
* `ME_OFFSET` - offset of the ME image in the vendor ROM
The `ifd.bin` must be created and can be checked in.
The default ROM input file is `blobs/$(BOARD)/$(BOARD).rom`,
and it *must not* be checked in.
This links in the AcpiTableDxe and AcpiPlatform executables from
the edk2 build tree and adds a depex dependency for the Linux
kernel on the AcpiTable being setup. The `acpi.cpio` file is
no longer included in the Linux kernel bzImage.
The `Makefile.nerf` has been re-written to generate the firmware
file system (FFS) files via rules.
TODO: figure out how to add LZMA compressed sections so that the
900k acpi tables can be compressed to about 100k.
