[zbin] Change fixup semantics to support ROMs over 128k uncompressed

2009-08-11T11:59:26+00:00

The option ROM header contains a one-byte field indicating the number of 512-byte sectors in the ROM image. Currently it is linked to contain the number of uncompressed sectors, with an instruction to the compressor to correct it. This causes link failure when the uncompressed size of the ROM image is over 128k. Fix by replacing the SUBx compressor fixup with an ADDx fixup that adds the total compressed output length, scaled as requested, to an addend stored in the field where the final length value will be placed. This is similar to the behavior of ELF relocations, and ensures that an overflow error will not be generated unless the compressed size is still too large for the field. This also allows us to do away with the _filesz_pgh and _filesz_sect calculations exported by the linker script. Output tested bitwise identical to the old SUBx mechanism on hd, dsk, lkrn, and rom prefixes, on both 32-bit and 64-bit processors. Modified-by: Michael Brown Signed-off-by: Michael Brown

[geniso] Emit proper error message for incorrect location of ISOLINUX_BIN

2009-08-08T23:05:49+00:00

If isolinux.bin is not installed in the expected location the error message shown is slightly misleading. Signed-off-by: Vibi Sreenivasan Signed-off-by: Michael Brown

[legal] Add the MIT and ISC licenses to licence.pl

2009-08-02T22:30:38+00:00

The MIT and ISC licenses are legally equivalent to the bsd2 license, but with slightly different verbiage. Signed-off-by: H. Peter Anvin Signed-off-by: Michael Brown

[build] Allow safe concurrent builds of .iso, .liso and .sdsk targets

2009-08-02T10:17:02+00:00

The geniso, genliso and gensdsk scripts contain hard-coded temporary directory names, and so could potentially collide with each other when run as part of a concurrent build (e.g. "make -j 4"). Fix by using mktemp to generate suitable temporary directory names.

[build] Make .liso image generation silent unless errors occur

[build] Add syslinux floppy image type .sdsk

2009-08-02T10:04:13+00:00

We add a syslinux floppy disk type using parts of the genliso script. This floppy image cat be dd'ed to a physical floppy or used in instances where a virtual floppy with an mountable DOS filesystem is useful. We also modify the genliso script to only generate .liso images rather than creating images depending on how it is called. Signed-off-by: Michael Brown

[legal] Add licence.pl and %.licence make target

2009-05-18T07:29:24+00:00

It is now possible to run e.g. make bin/rtl8139.dsk.licence in order to see a licensing assessment for any given gPXE build. The assessment will either produce a single overall licence for the build (based on combining all the licences used within the source files for that build), or will exit with an error stating why a licence assessment is not possible (for example, if there are files involved that do not yet contain an explicit FILE_LICENCE() declaration).

[build] Fix signed/unsigned division in util/zbin.c

2009-04-26T04:48:15+00:00

Commit b149a99 ([build] Round up SUBx deltas) introduced a signed/unsigned issue that affects gPXE images built on 32-bit hosts. The zbin fixup utility performed an unsigned division, which led to .usb images with an incorrect number of sectors to load. The issue snuck by on 64-bit hosts since uint32_t is promoted to long. On 32-bit hosts it is promoted to unsigned long. Modified-by: Michael Brown Signed-off-by: Michael Brown

[build] Simplify use of Getopt::Long in padimg.pl

Sometimes it's just so much fun doing things the complicated way that you forget to check the man page for the existence of a simpler syntax.

[build] Reinstate the .pdsk padded-floppy image format

2009-04-16T05:01:07+00:00

Some utilities that expect a floppy disk image (e.g. iLO?) may test for a file of the correct size. Reinstate the .pdsk image format in order to provide this if needed.
