[bios] Add bin-x86_64-pcbios build platform

2016-02-16T19:32:32+00:00

Move most arch/i386 files to arch/x86, and adjust the contents of the Makefiles and the include/bits/*.h headers to reflect the new locations. This patch makes no substantive code changes, as can be seen using a rename-aware diff (e.g. "git show -M5"). This patch does not make the pcbios platform functional for x86_64; it merely allows it to compile without errors. Signed-off-by: Michael Brown

[build] Search for ldlinux.c32 separately from isolinux.bin

2015-09-01T20:04:44+00:00

Some distributions (observed with Ubuntu 15.04) place ldlinux.c32 in a separate directory from isolinux.bin. Search for these files separately, and allow an alternative location of ldlinux.c32 to be provided via LDLINUX_C32=... on the make command line.

[build] Allow ISA ROMs to be built

2014-08-22T16:34:07+00:00

The build process has for a long time assumed that every ROM is a PCI ROM, and will always include the PCI header and PCI-related functionality (such as checking the PCI BIOS version, including the PCI bus:dev.fn address within the ROM product name string, etc.). While real ISA cards are no longer in use, some virtualisation environments (notably VirtualBox) have support only for ISA ROMs. This can cause problems: in particular, VirtualBox will call our initialisation entry point with random garbage in %ax, which we then treat as the PCI bus:dev.fn address of the autoboot device: this generally prevents the default boot sequence from using any network devices. Create .isarom and .pcirom prefixes which can be used to explicitly specify the type of ROM to be created. (Note that the .mrom prefix always implies a PCI ROM, since the .mrom mechanism relies on reconfiguring PCI BARs.) Make .rom a magic prefix which will automatically select the appropriate PCI or ISA ROM prefix for ROMs defined via a PCI_ROM() or ISA_ROM() macro. To maintain backwards compatibility, we default to building a PCI ROM for anything which is not directly derived from a PCI_ROM() or ISA_ROM() macro (e.g. bin/intel.rom). Add a selection of targets to "make everything" to ensure that the (relatively obscure) ISA ROM build process is included within the per-commit QA checks. Signed-off-by: Michael Brown

[build] Merge util/geniso and util/genliso

[build] Use $(eval) if available

2013-05-14T13:28:30+00:00

When the $(eval) function is available (in GNU make >= 3.80), we can evaluate many of the dynamically-generated Makefile rules directly. This avoids generating a few hundred Makefile fragments in the filesystem, and so speeds up the build process. Signed-off-by: Michael Brown

[pxe] Provide PXENV_FILE_EXIT_HOOK only for ipxelinux.0 builds

2011-12-11T02:28:04+00:00

PXENV_FILE_EXIT_HOOK is designed to allow ipxelinux.0 to unload both the iPXE and pxelinux components without affecting the underlying PXE stack. Unfortunately, it causes unexpected behaviour in other situations, such as when loading a non-embedded pxelinux.0 via undionly.kpxe. For example: PXE ROM -> undionly.kpxe -> pxelinux.0 -> chain.c32 to boot hd0 would cause control to return to iPXE instead of booting from the hard disk. In some cases, this would result in a harmless but confusing "No more network devices" message; in other cases stranger things would happen, such as being returned to the iPXE shell prompt. The fundamental problem is that when pxelinux detects PXENV_FILE_EXIT_HOOK, it may attempt to specify an exit hook and then exit back to iPXE, assuming that iPXE will in turn exit cleanly via the specified exit hook. This is not a valid assumption in the general case, since the action of exiting back to iPXE does not directly cause iPXE to exit itself. (In the specific case of ipxelinux.0, this will work since the embedded script exits as soon as pxelinux.0 exits.) Fix the unexpected behaviour in the non-ipxelinux.0 cases by including support for PXENV_FILE_EXIT_HOOK only when using a new .kkkpxe format. The ipxelinux.0 build process should therefore now use undionly.kkkpxe instead of undionly.kkpxe. Signed-off-by: Michael Brown

[exeprefix] Add .exe prefix

2011-03-28T01:10:14+00:00

An iPXE .exe image can be loaded from DOS. Tested using bin/ipxe.exe to load a Linux kernel and simple initramfs from within MS-DOS 6.22. (EDD must be disabled using the "edd=off" kernel parameter, since the loaded kernel image has already overwritten parts of DOS' INT 13 wrapper.) Signed-off-by: Michael Brown
