...so I decided that that was probably something that really should be published more widely. This is the *current state* of the core32 branch; all this stuff is subject to change as development progresses: *** Call from real mode (16-bit) to protected mode (32-bit): These calls are done with the pm_call macro: extern pm_func pm_call pm_func the "extern" just tells NASM this is a symbol from outside the file; it has the effect of being a prototype. I have started collecting the external symbols into the header file extern.inc just to avoid cluttering things up too badly, although the...

Hi, I recently ran into an issue where the dependencies generated in modules.dep created a circular reference, which meant that qemu spun forever in modules_load_dependencies(). I did think about detecting this kind of circular dependency at modules.dep generation time but if we ever move to using DT_NEEDED to track dependencies we would need this functionality in the elflink core anyway.

...ars unaffected by hybridization, it's still something to check. I started reading over my recent build of bios/core/isolinux.lst (which should reflect how the ASM of isolinux.bin looks in RAM), I found there's a bunch of protected mode calls before this. isolinux.asm:1119:init.inc:32 "pm_call pm_decompress" should be the first. A similar push/mov/call/pop should help. -- -Gene

From: Matt Fleming <matt.fleming at intel.com> Here are the patches that I've got queued up based on the very helpful feedback I received from people testing Syslinux 5.00-pre9. Unless anyone has any concerns these will make it into Syslinux 5.00-pre10. Matt Fleming (9): pxe: Don't call open_config() from the pxe core ldlinux: Print a warning if no config file is found

From: Matt Fleming <matt.fleming at linux.intel.com> This is a series of patches that, * shrink the core by moving things into an ldlinux ELF module * begin wiring up some of the C versions of various functions The core now only contains essential code and loads the ldlinux module to do everything else, like providing a command line interface and loading kernels.

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4. Having to jump through the comboot API for localboot support is less than ideal and I'll eventually fix that, probably when we move a big chunk of code from asm to C. Also, there's a

From: Matt Fleming <matt.fleming at intel.com> The following patch series is available at, git://git.zytor.com/users/mfleming/syslinux.git elflink All patches are against the 'elflink' branch. This series fixes a few serious bugs and some behavioural incompatibilities with the 4.x series. Matt Fleming (19): ldlinux: Initialise 'p' before using it. ldlinux: Parse
