build: refactor JSON info files to `profiles.json`

2020-04-03T10:17:45Z

JSON info files contain machine readable information of built profiles and resulting images. These files were added in commit 881ed09ee6e2 ("build: create JSON files containing image info"). They are useful for firmware wizards and script checking for reproducibility. Currently all JSON files are stored next to the built images, resulting in up to 168 individual files for the ath79/generic target. This patch refactors the JSON creation to store individual per image (not per profile) files in $(BUILD_DIR)/json_info_files and create an single overview file called `profiles.json` in the target directory. Storing per image files and not per profile solves the problem of parallel file writes. If a profiles sysupgrade and factory image are finished at the same time both processes would write to the same JSON file, resulting in randomly broken outputs. Some target like x86/64 do not use the image code yet, resulting in missing JSON files. If no JSON info files were created, no `profiles.json` files is created as it would be empty anyway. As before, this creation is enabled by default only if `BUILDBOT` is set. Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.

x86: generate EFI platform bootable images

2020-03-31T14:20:47Z

Add EFI platform bootable images for x86 platforms. These images can also boot from legacy BIOS platform. EFI System Partition need to be fat12/fat16/fat32 (not need to load filesystem drivers), so the first partition of EFI images are not ext4 filesystem any more. GPT partition table has an alternate partition table, we did not generate it. This may cause problems when use these images as qemu disk (kernel can not find rootfs), we pad enough sectors will be ok.

x86: switch image generation to new code

2020-03-21T10:36:00Z

This commit introduces few related changes which need to be done in single commit to keep images buildable between git revisions. In result it retains all previous image creation possibilities with slight name change of generated images. Brief summary of the commit: * Split up image generation recipe to smaller chunks to make it more generic and reusable. * Make iso images x86 specific and drop their definition as root filesystem. * Convert image creation process to generic code specified in image.mk. * Make geode subtarget inherit features from the main target instead of redefining them. * For subtargets create device definitions with basic packages set.

x86: make crashdump works

1. KERNEL_CRASH_DUMP should depends on KERNEL_PROC_KCORE (kexec use it) 2. select crashkernel mem size by totalmem mem <= 256M disable crashkernel by default mem >= 4G use 256M for crashkernel mem >= 8G use 512M for crashkernel default use 128M 3. set BOOT_IMAGE in kdump.init 4. resolve a "Unhandled rela relocation: R_X86_64_PLT32" error Tested on x86_64 Signed-off-by: Chen Minqiang

kernel: Use new symbol to deactivate MIPS FPU support

2020-02-28T16:50:46Z

With kernel 5.4 the upstream kernel supports deactivating the FPU support on MIPS. Use this new upstream feature instead of our older patch which was removed when porting the kernel patches to kernel 5.4. This way both options are set which should work for older kernel versions and also new ones. Signed-off-by: Hauke Mehrtens

base-files: add all buildinfo with INCLUDE_CONFIG

2020-02-27T11:14:09Z

CONFIG_INCLUDE_CONFIG option is helpful for being able to rebuild the exact same firmware as you see on a live OpenWRT instance, but it's crucially missing feeds information, so we can't rebuild the exact same package versions. This commit fixes this by adding the remaining feeds (and version) buildinfo files to the image. Signed-off-by: Xu Wang
