2024-08-20	util/cbfstool/cbfs-payload-linux: Add error handling	Maximilian Brune
	This adds some error handling to the code that adds the input segments (e.g. kernel, cmdline, initrd...) to the output file. Currently the compress function can fail and coreboot will still build "successfully" leaving whoever build coreboot puzzled.

2024-08-19	util/cbfstool/cbfs-payload-linux: Do not compress bzImage	Maximilian Brune
	Compressing the already compressed bzImage does not yield any fruit. If you are lucky it actually makes the image a little bit smaller. If you are unlucky the image actually gets bigger and since the compressing function is not checked for any errors, coreboot just builds successfully even though the payload is broken through compression. Before this patch you could possibly get this error during compilation: ``` E: LZMA: LzmaEnc_Encode failed 9. ``` and your linux payload would end up something like this in CBFS: ``` FMAP REGION: COREBOOT Name Offset Type Size Comp .... fallback/payload 0x1c9c0 simple elf 511 none .... ``` That doesn't stop coreboot from finishing the build though, since we currently don't check for errors from the compression. That is an issue for another patch though. Tested: Build and run QEMU-Q35 with Linux bzImage as payload.

2023-08-03	linux_trampoline: Handle 64-bit framebuffer addresses	Nico Huber
	To support full 64-bit addresses, there is a new field `ext_lfb_base` since Linux 4.1. It is unclear, however, how a loader is supposed to know if the kernel is compatible with this. Filling these previously reserved bits doesn't hurt, but an old kernel would probably ignore them and not know that it's handling a clipped, invalid address. So we play safe, and only allow 64-bit addresses for kernels after the 2.15 version bump of the boot protocol.

2016-03-03	cbfstool: Initialize contents of linux_params to 0	Werner Zeh
	When linux is used as payload, the parameters to the kernel are build when cbfstool includes bzImage into the image. Since not all parameters are used, the unused will stay uninitialized. There is a chance, that the uninitialized parameters contain random values. That in turn can lead to early kernel panic. To avoid it, initialize all parameters with 0 at the beginning. The ones that are used will be set up as needed and the rest will contain 0 for sure. This way, kernel can deal with the provided parameter list the right way.

2014-09-04	cbfstool:linux_trampoline: config CS and DS segment descriptors	Curt Brune
	The Linux trampoline code does not set up the segment descriptors for __BOOT_CS and __BOOT_DS as described in the Linux kernel documentation: ... a GDT must be loaded with the descriptors for selectors __BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat segment; __BOOT_CS must have execute/read permission, and __BOOT_DS must have read/write permission; This is not a problem when launching a Linux payload from coreboot, as coreboot configures the segment descriptors at selectors 0x10 and 0x18. Coreboot configures these selectors in the ramstage to match what the Linux kernel expects (see coreboot/src/arch/x86/lib/c_start.S). When the cbfs payload is launched in other environments, SeaBIOS for example, the segment descriptors are configured differently and the cbfs Linux payload does not work. If the cbfs Linux payload is to be used in multiple environments should the trampoline needs to take care of the descriptors that Linux requires. This patch updates the Linux trampoline code to configure the 4G flat descriptors that Linux expects. The configuration is borrowed from the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for selectors 0x10 and 0x18. The linux_trampoline code is slightly refractored by defining the trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC. This definition is moved into a separate header file, linux_trampoline.h. This header file is now included by both the trampoline assembly language code and the trampoline loader C code. The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC as scratch space for the sgdt CPU instruction. Testing Done: Verified the Linux payload is booted correctly in the following environments: 1. Coreboot -> Linux Payload 2. Coreboot -> SeaBIOS -> Linux Payload: (previously did not work) Change-Id: I888f74ff43073a6b7318f6713a8d4ecb804c0162 Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Reviewed-on: http://review.coreboot.org/6796 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.
