* Fix all warnings, and better separate code that should not be mixedsyslinux-6.04-pre3H. Peter Anvin (Intel)2019-02-071-1/+1
| | | | | | | | | Clean up a number of warnings in the tree. Refactor especially the core code so we don't end up building a bunch of BIOS-specific code for EFI, and general build cleanups. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
* mem: Calling int15 for 0x8800Erwan Velu2014-01-231-0/+1
| | | | | | | | On some code, the intcall 0x15 was missing when playing with 0x8800 making code useless. That's not a big deal since e820 or e801 shall be provided by host but anyway, let's fix it ;)
* com32sys_t inreg shall be zeroified prior intcallErwan Velu2014-01-221-0/+2
| | | | | | | | | | | 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 all references to __com32.cs_bounceMatt Fleming2012-06-081-10/+25
| | | | | | | | | The COM32 cs_bounce buffer is not usable with ELF modules, as we're trying to move to an environment where memory is dynamically allocated. All users of __com32.cs_bounce have been converted to using lmalloc() to allocate low memory. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
* Run Nindent on com32/mboot/mem.cH. Peter Anvin2009-05-291-137/+136
| | | | | | | | | Automatically reformat com32/mboot/mem.c using Nindent. Do this for all files except HDT, gPXE and externally maintained libraries (zlib, tinyjpeg, libpng). Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Drop support for ACPI 3 E820 extended memory attributesH. Peter Anvin2009-05-211-9/+0
| | | | | | | | | | | | | | Drop all support for ACPI 3 E820 extended memory attributes. There are BIOSes in the field that report completely bogus information here, resulting in no memory at all being detected (we then fall back to E801 detection, but that is problematic in its own ways.) There is strong reasons to believe at this point that the extended memory attributes are not usable in their current form, so drop them and revert back to simple 20-byte support, including for MEMDISK spoofing.

* mboot: fix cmdline; a few more layout tweaksH. Peter Anvin2009-04-261-1/+1
| | | | | | | | | | Fix module command lines (it was overwriting the main kernel command line); a few minor layout tweaks. In particular, we require the section header to be page-aligned, but not the subsequent sections. With this, I can get Xen to boot. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* First attempt at a rewritten mboot moduleH. Peter Anvin2009-04-261-0/+215
First attempt at rewriting the mboot module to use the Syslinux shuffle APIs. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
