v2 cover Bump and improve syslinux (branch yem/syslinux)

From: "Yann E. MORIN" <[email protected]>

Hello All!

Here are a few patches to bump and enhance syslinux:
- patches 1..4: preparatory fixing and cleanup patches
- patches 5..6: new pacakges, dependency of the new syslinux
- patch 7 : actual syslinux bump
- patches 8..9: new options to install new types of blobs

To be noted, the syslinx build system is, well, a bit weird, to say the least. There is I hope extensive-enough information about this in the bump-patch. Please pay it a bit of attention, it is really convoluted, and would benefit from some in-depth review.

Thanks to Frank for his preliminary work on ucl and upx, and to Thomas L. whose extlinux patch prompted me to look at syslinux. ;-)

Changes v1 -> v2:
- explain the need for an ia32 compiler (Arnout)
- make the image selection a choice (Arnout)
- improve upx commit log (Arnout)
- typoes (Arnout)
- improve help entry for the mbr option

Regards,
Yann E. MORIN.

PATCH v2 1/9 boot/syslinux: needs an ia32-capable compiler

From: "Yann E. MORIN" <[email protected]>

The pxelinux and isolionux images are 32-bit binaries, so we need a compiler that can generate them (ie. a compiler that understands -m32).

PATCH v2 2/9 boot/syslinux: prepare to install non-core images

In reply to Yann E. MORIN

From: "Yann E. MORIN" <[email protected]>

Currently, we hard-code the path to the images we install, and expect them to be from the core/ sub-dir.

Not all images we can install are located in core/. For example, the efi boot images (to come later) are not located in core/.

Prepare the upcoming installation of extlinux by not expecting images are in core/.

PATCH v2 3/9 boot/syslinux: make the sub-options a choice

In reply to Yann E. MORIN

From: "Yann E. MORIN" <[email protected]>

Currently it is possible to choose either, both or none of the pxelinux or isolinux images.

But it does not make sense to build none or both, as we need at least one to boot the target, and the target can use more than one.

So, we need one and only one image to be selected at once.

PATCH v2 5/9 package/ucl: new package

In reply to Yann E. MORIN

From: Frank Hunleth <[email protected]>

UCL implements a number of compression algorithms that achieve an excellent compression ratio while allowing *very* fast decompression. Decompression requires no additional memory.

This is needed for UPX, which is needed for syslinux 6.x.

PATCH v2 6/9 package/upx: new package

In reply to Yann E. MORIN

From: Frank Hunleth <[email protected]>

UPX is a free, portable, extendable, high-performance executable packer for several executable formats.

This is needed for syslinux 6.x.

Note: upx is a host-only package. Although it supports quite a few target architectures, the only use so far wil be syslinux, which already has an x86-on-x86 requirement anyway. So we currently do not care to have target-dependencies on host-upx.

PATCH v2 7/9 boot/syslinux: bump version

In reply to Yann E. MORIN

From: "Yann E. MORIN" <[email protected]>

This new version has a very, very weird build system. There are different images that syslinux can now build:
- the plain legacy-bios images we already supported previously
- two new EFI32 and EFI64 applications

To build one or the other, the Makefile accepts one or more of:

    make (bios|efi32|efi64)

Specify all of them, and it builds all. Specify 'install', and it installs all of them, as one may expect.

Still a regular behaviour, is to build only a subset (down to one):
make bios <-- builds just the legacy-bios images
make efi32 bios <-- builds just the legacy-bios and efi32 images

Where it gets weird is the install procedure. Can you guess how it's done?
Hint: the syslinux guys have invented the multiple-argument parsing in pure Makefiles. To build then install only the bios images, one would do:
make bios
make bios install

Yep, that's it. make bios install. Two arguments, one action.

That makes for some funky workarounds in our install procedure...

'bios' is the only image we support so far, with efi to come in a future patch.

Using MAKE1, as there are issues with highly-parallel builds.

Yann and all,

Hello All!

Here are a few patches to bump and enhance syslinux:
- patches 1..4: preparatory fixing and cleanup patches
- patches 5..6: new pacakges, dependency of the new syslinux
- patch 7 : actual syslinux bump
- patches 8..9: new options to install new types of blobs

This series works for me (MBR option):

Tested-by Frank Hunleth <[email protected]>

Thanks,
Frank

Quoted 63 lines

To be noted, the syslinx build system is, well, a bit weird, to say the least. There is I hope extensive-enough information about this in the bump-patch. Please pay it a bit of attention, it is really convoluted, and would benefit from some in-depth review.

Thanks to Frank for his preliminary work on ucl and upx, and to Thomas L. whose extlinux patch prompted me to look at syslinux. ;-)

Changes v1 -> v2:
- explain the need for an ia32 compiler (Arnout)
- make the image selection a choice (Arnout)
- improve upx commit log (Arnout)
- typoes (Arnout)
- improve help entry for the mbr option

Regards,
Yann E. MORIN.

I did a quick test on real hardware with extlinux 6.02 and BIOS-legacy configuration. I reused the same config as for 5.10-pre4, so it's ok for me :)

Tested using serial port and menu.c32 module.

Tested-by Romain Naour <[email protected]>

Note: all *.c32 modules for the target are installed in $(HOST_DIR)/usr/share/syslinux/ They can be installed in $(STAGING_DIR) instead ?

Thanks,
Romain Naour

What are those .c32 modules? How are they to be used?

From what I can infer, I doubt we want them in $(STAGING_DIR); they probably belong to either somewhere in $(TARGET_DIR) (in /boot ?) or to $(IMAGES_DIR).

Regards,
Yann E. MORIN.
