* board/pc: drop unused grub-efi.cfg fileGravatar Thomas Petazzoni2019-05-102-13/+1
| | | | | | | | | | | | | | | | | | | | | | | Following commit fee29b05bb7db25e37c8a5175ce00dc712554edf ("configs/pc_x86_64_efi: use a GPT partition table"), board/pc/grub-efi.cfg is no longer used anywhere: the post-image-efi-gpt.sh script generates the grub configuration. Also, since post-image-efi-gpt.sh generates a grub configuration file that uses the root filesystem partition UUID as the root= kernel argument, the instructions in the readme.txt file to tweak root= from /dev/sda2 to /dev/vda2 is no longer relevant. This was noted in the commit log of fee29b05bb7db25e37c8a5175ce00dc712554edf: The root filesystem location is passed to the kernel by a partition UUID, so it is possible to boot on QEMU, directly from the disk image, or dump the image to a physical device.

* configs/pc_x86_64_efi: use a GPT partition tableGravatar Carlos Santos2019-02-064-41/+67
| | | | | | | | | | | | | | | | | | | | | Since all EFI-based systems support GPT, this commit changes pc_x86_64_efi to use a GPT partition table. It shows an example of how to craft a disk image with GPT partitioning instead of MBR. This is achieved by means of a post-image script which uses mkdosfs+mcopy+sfdisk, since genimage is unable to deal with GPT. Long term, it would be ideal if genimage had GPT support, but until then, this script shows how to achieve creating a GPT-based disk image. The script was kept as simple as possible to make it easy to understand and adapt for other purposes. The root filesystem location is passed to the kernel by a partition UUID, so it is possible to boot on QEMU, directly from the disk image, or dump the image to a physical device.

* board/pc: ensure grub.cfg is copied to target filesystemGravatar Grégoire Delattre2018-12-312-14/+15
| | | | | | | | | | | | | | | Before this commit, the grub configuration file was copied to the TARGET_DIR in a post-image hook, after the filesystem has been generated. It was kinda working because the board/pc's grub configuration and the default one are the same and the later was copied during the build process of the grub2 package. This commit ensures the custom board/pc grub configuration is copied at the right time.

* board/pc: use frame pointer unwinder in linux.configGravatar Thomas Petazzoni2018-11-231-0/+1
| | | | | | | | | | | | | The default ORC unwinder requires libelf to be built. While we could build libelf using BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF, we probably don't really need the ORC unwinder in the PC defconfigs, so let's use the frame pointer unwinder instead.

* configs/pc: refactor to use genimage and grub.cfgGravatar Erico Nunes2017-10-223-25/+16
| | | | | | | | | | | This simplifies the pc configs and respective post image scripts to use the shared genimage script and separate grub config files. Separate grub files are cleaner to maintain and easier to copy and modify, for example to support booting the pc defconfigs in qemu.

* configs/pc_x86_64_{bios,efi}_defconfig: use custom linux configGravatar Peter Korsgaard2017-06-152-45/+84
| | | | | | | | | | | | | | | Reusing the qemu x86-64 linux config isn't very obvious, so these defconfigs aren't taken into consideration when the qemu defconfigs are updated, breaking the build. Instead use a custom linux config for the pc defconfigs. With this, we also can get rid of the fragment file containing the delta fra the qemu config. Created by linux-update-defconfig (after turning of the fragment file). Also drop the linux kernel version number from the file name as it just causes extra noise whenever the kernel is bumped.

* configs/pc_x86_64_efi_defconfig: enable kernel EFI supportGravatar Erico Nunes2016-08-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | The pc_x86_64_efi reference defconfig is targeted towards an EFI environment but the kernel which comes with it does not enable EFI support by default. Booting this defconfig without kernel EFI support on a qemu virtual machine with EFI firmware resulted in no output to tty1 or ttyS0. Enabling EFI support in the kernel fixed this and seems saner for an EFI reference Buildroot defconfig. Adding CONFIG_EFI to board/pc/linux-extras.config also affects pc_x86_64_bios_defconfig which doesn't require it, however it was observed that the extra overhead is small and so this is preferred rather than having a separate config file. This was tested with qemu 2.6.0 running with kvm enabled and firmware EFI v2.60 by EDK II. Also built and verified bios defconfig on the same setup but with BIOS firmware instead.

* configs/pc_x86_64_{bios, efi}_defconfig: new samplesGravatar Gustavo Zacarias2016-06-035-0/+169
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>
