* pxe_dns: remove obsolete pxe_dns.c wrapperH. Peter Anvin2016-04-061-1/+1
| | | | | | | | | We used to need a wrapper around the core function dns_resolv() to implement pxe_dns(), because the former function required its argument to live in low memory. This is no longer the case and hasn't been for a while, so remove this unnecessary level of indirection. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* | | Add per-firmware object directory supportMatt Fleming2012-10-161-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have multiple firmware backends it no longer makes sense to write object files to the same directory as their source. A better solution is to write the object files to a per-firmware directory under a top-level object directory. The top-level object directory can be specified on the command-line with the O= variable, e.g. make O=/tmp/obj. If no top-level object directory is specified an 'obj' directory is created in the top-level of the Syslinux source repository. All the existing make targets continue to work as before, however now they apply to all firmware backends, e.g. 'make installer' will build the BIOS, 32-bit EFI and 64-bit EFI installers and place them under $(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively. Note unlike every other bit of Syslinux, the gpxe objects are still kept in the src directory, e.g. gpxe/src, since gpxe is only required by the BIOS backend. It is possible to specify a make target for a specific firmware or list of firmware with the following syntax, make [firmware[,firmware]] [target[,target]] To clean the object directory for just the BIOS firmware type, 'make bios clean' To build both the 32-bit and 64-bit EFI installers type, 'make efi32 efi64 installer' Since the Syslinux make infrastructure is now more complex a new file doc/building.txt has been created to explain how to build Syslinux. The top-level Makefile now exports some make variables for use in module Makefiles, - topdir - the top-level source directory of the Syslinux repository, e.g. /usr/src/syslinux - objdir - the top-level object directory for the firmware backend currently being built, e.g. /obj/syslinux/bios - SRC - the source directory in the Syslinux repository for the module currently being built, e.g. /usr/src/syslinux/com32/libupload - OBJ - the object directory for the module currently being built, e.g. /obj/syslinux/bios/com32/libupload Since we're rewriting the Makefile infrastructure anyway it seemed like a good idea to add parallel support. By writing subdirectories as prequisites for make targets the objects in those subdirectories can be built in parallel. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| * | com32: Use --as-needed for LDFLAGSMatt Fleming2012-07-201-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends commit 4678fd92a21e ("elflink: fix dependency problem in cmenu/Makefile") and basically reverts commit fb543aa635ff ("com32: Per-object file LDFLAGS"). By using the --as-needed ld argument we can specify all the required shared libraries for a directory, even if not all of the libraries are needed by every .c32 file. --as-needed takes care of only creating DT_NEEDED entries for the shared libraries that are actually required to resolve undefined symbols in a given module. Furthermore, by using $(LIBS) we create a dependency between .c32 files and their shared libraries, which allows multiple make jobs to run in parallel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This involved some other changes, such as passing flags to unload_pxe() now that we only call it from C code, and hence don't need to update KeepPXE.

| * | Revert "pxe: resolve names via DNS from protected-mode code"Matt Fleming2012-06-201-4/+17

We need a way to implement DNS resolution so that it works for PXELINUX but returns an error for SYSLINUX/EXTLINUX or ISOLINUX, without introducing undefined symbols. The old COMBOOT API method worked splendidly for this, so revert until someone provides a better solution.

| * pxe: resolve names via DNS from protected-mode codePaulo Alcantara2012-05-121-17/+4
| | | | | | | | | | | | | | | | | | | | | | Syslinux used to call __intcall() for calling routines of the old COMBOOT API to resolve names via DNS (INT 22h, AX=0x0010) that seemed pointless, since INT 22h, AX=0x0010 does call the protected-mode function pm_pxe_resolv_dns() when calling INT 22h, AX=0x0010. So, for resolving names via DNS we must call pxe_dns_resolv() (a protected-mode function) instead for now. Signed-off-by: Paulo Alcantara <pcacjr@zytor.com>

* elflink: Make ELF the default object formatMatt Fleming2011-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | com32/elflink/modules was originally created to house ELF modules and keep them separate from the COM32 modules as the elflink branch was being developed. However, this has inadvertently created a maintenance nightmare because code was copied from elsewhere in the tree into com32/elflink/modules, resulting in duplication. Bug fixes have been going into the original code but have not been merged onto the elflink branch, leaving the duplicate code in com32/elflink/modules buggy. So let's delete this directory. There really is no reason to keep ELF and COM32 modules separate because there's no reason to need both COM32 and ELF modules to coexist. ELF is a far superior object file format and all modules are not emitted as ELF objects. Now that we're outputting ELF modules we can use dynamic memory instead of the cs_bounce bounce buffer. This commit requires a certain amount of shuffling for some files. quicksort.c isn't a module and belongs as part of the util library. cli.h belongs in com32/include so that other modules can make use of the cli code in ldlinux.c32. All libraries are now ELF shared libraries which are only loaded to fixup unresolved symbols for executable modules and renamed from *.a to *.c32. This reduces the runtime memory footprint because libraries are only loaded when needed and because every executable no longer gets its own copy of code/data (as it would if linking with a static library). Also, remove MINLIBOBJS from libcom32.c32 because it is already part of libcom32min.a and we don't want to have any duplicate symbols between the core (which links with libcom32min.a) and libcom32.c32.

This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including.
