configs/pc_x86_64_{bios, efi}_defconfig: new samples
Add two new sample defconfigs oriented towards real PC targets. It adds two variants for BIOS and EFI boot strategy. On the build side we enable eudev to autoload relevant kernel modules/support when necessary. It adds a bunch of drivers and extra filesystem support which is by no means extensive/complete, mostly geared towards the hardware i've got at hand to test with. This is accomplished by adding on top of the Qemu x86_64 kernel sample config. Build connman since by using eudev network interfaces get renamed on boot thus complicating any form of automatic and friendly bringup. It also makes Wi-Fi configuration/support easier. In principle these base defconfigs should work just fine for other storage media != pendrive like sata or ssd disk, however driver support isn't there quite yet, and pendrive is mostly supported by usb storage plus the usual usb host controller drivers. Tested on old Lenovo laptop (BIOS) and Asus Zenbook (EFI). Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Bare PC sample config
|
||||
=====================
|
||||
|
||||
1. Build
|
||||
|
||||
First select the appropriate target you want.
|
||||
|
||||
For BIOS-based boot strategy:
|
||||
|
||||
$ make pc_x86_64_bios_defconfig
|
||||
|
||||
Or for EFI:
|
||||
|
||||
$ make pc_x86_64_efi_defconfig
|
||||
|
||||
Add any additional packages required and build:
|
||||
|
||||
$ make
|
||||
|
||||
2. Write the pendrive
|
||||
|
||||
The build process will create a pendrive image called sdcard.img in
|
||||
output/images.
|
||||
|
||||
Write the image to a pendrive:
|
||||
|
||||
$ dd if=output/images/sdcard.img of=/dev/sdc; sync
|
||||
|
||||
Once it's done insert it into the target PC and boot.
|
||||
|
||||
Remember that if said PC has another boot device you might need to
|
||||
select this alternative for it to boot.
|
||||
|
||||
In the case of EFI boot you might need to disable Secure Boot from
|
||||
the setup as well.
|
||||
|
||||
3. Enjoy
