* com32: Use z size specifier for printf-ing size_t variableMartin Str|mberg2015-01-051-2/+2
| | | | | | | | | Use the z size specifier to printf-ing size_t variables to get rid of gcc warning format ‘%08x’ expects type ‘unsigned int’, but argument 2 has type ‘long unsigned int’ Author: Martin Str|mberg <ams@ludd.ltu.se> Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* build: sort sources to build in a more deterministic wayPhilippe Coval2015-01-051-2/+2
| | | | | | | | | | | | | | | | | It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible.

* sysdump: Remove README that was for memdump, not sysdumpH. Peter Anvin2014-06-101-19/+0
| | | | | | | Sysdump was forked from memdump, but the README was never fixed. It should be updated, but until then, delete it. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* com32sys_t inreg shall be zeroified prior intcallErwan Velu2014-01-222-0/+3
| | | | | | | | | | | As per commit f775e740a3a817a4ff5ba26bea99dbfd735456b3, inreg parameters of intcall() shall be zeroified. Having unclean inreg could trigger bad behaviors on some hosts. This patch is about adding memset() calls prior any intcall() : - some intcall didn't had any memset at all - some successive intcall() calls didn't memset inreg in between calls

| * Delete 16-bit COMBOOT supportsyslinux-5.00Matt Fleming2012-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | 16-bit COMBOOT files are no longer supported by Syslinux in 5.00 so delete all references and change any 32-bit COMBOOT image references to mention ELF instead. Some of the COMBOOT stuff is still used internally so we can't nuke core/comboot.inc yet, but that will disappear in a future release. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
* | Add per-firmware object directory supportMatt Fleming2012-10-161-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Archicture-dependent get_cpuid in sysdump/cpuid is fixed.chandramouli narayanan2012-06-251-0/+11
|/ | | | | | | | | | | In the following sample programs zzjson.c, advdump.c, entrydump.c, hello.c, resolv.c, serialinfo.c in com32/samples, the following code call hangs the program: openconsole(&dev_null_r, &dev_stdcon_w); The following fix works: openconsole(&dev_rawcon_r, &dev_ansiserial_w); Remanants of the unused old i386-only files, if any, need to be pruned.
* elflink: Make ELF the default object formatMatt Fleming2011-04-261-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* com32: console is already initialised when we enter main()Matt Fleming2011-04-261-1/+0
| | | | | | | | | There's no need to initialise the console when we enter main() as ldlinux.c32 will already have initialised it for us. Leaving the calls to openconsole() causes the console settings to be reset whenever we run a module. Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the MCONFIG files into a mk/ directory and give them more descriptive names. 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. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>
