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.
To be able to boot a disk image, passed to QEMU with `-hda
/path/qemu.img`, the appropriate modules are needed. Strange, `libata`
is not enough, and the drive is only detected, when the module `ahci` is
loaded.
> ata1.00: ATA-7: QEMU HARDDISK, 2.5+, max UDMA/100
Tested with QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7)
with the command below,
qemu-system-x86_64 -enable-kvm -M q35 -m 1G -bios \
qemu-coreboot/coreboot.rom -serial stdio -L /dev/shm -hda \
/dev/shm/qemu-debian.img
where `qemu-debian.img` is created with grml-debootstrap.
grml-debootstrap --vmfile --vmsize 3G --target \
/dev/shm/qemu-debian.img -r sid
Currently the TPM counter label is hard-coded. By changing it to a
variable in this function we can reuse all of the TPM counter functions
to create other monotonic counters in the TPM (if the hardware supports
it) with custom labels.
Wrapping text to 80 characters works but due to font size and padding
the maximum 80 character lines start to get truncated. Extending the
window to 90 characters will resolve this.
While the whiptail program wraps text appropriately based on column
size, the fbwhiptail program doesn't, leading to text that scrolls off
the window where it can no longer be read. This change wraps the longer
text output so it all fits.
Since fbwhiptail allows us to customize the background colors, we should
colorize warnings and error messages to provide a user with an
additional subtle cue that there might be a problem. I have added two
additional configuration options:
CONFIG_WARNING_BG_COLOR
CONFIG_ERROR_BG_COLOR
and in the librem13v2.config file you can see an example for how to set
them to be yellow and red gradients, respectively. I've also updated the
main two scripts that use whiptail to include those background colors.
If you decide to use regular whiptail, just don't set these config
options and it should behave as expected.
