Michael Brown	0015601f0b	[gdb] Fix a compiler warning that shows up only when assertions are enabled gcc should (I think) be warning about this anyway, but seems to do so only when assertions are enabled for this object.	vor 15 Jahren
Michael Brown	e3c5507178	[i386] Add dump_regs() debug call Use as "call dump_regs" from any real-mode code within .text16. Should preserve all registers and flags.	vor 15 Jahren
Michael Brown	ca0b0f0616	[relocate] Guard against systems that report empty memory regions If the INT 15,e820 memory map reports a region [0,0), this confuses the "truncate to even megabytes" logic, which ends up rounding the region 'down' to [0,fff00000). Fix by ensuring that the region's end address is at least 1, before we subtract 1 to obtain the "last byte in region" address.	vor 16 Jahren
Michael Brown	320b072c7a	[pcbios] Support arbitrary splits of the e820 memory map Allow for an arbitrary number of splits of the system memory map via INT 15,e820. Features of the new map-mangling algorithm include: Supports random access to e820 map entries. Requires only sequential access support from the underlying e820 map, even if our caller uses random access. Empty regions will always be stripped. Always terminates with %ebx=0, even if the underlying map terminates with CF=1. Allows for an arbitrary number of hidden regions, with underlying regions split into as many subregions as necessary. Total size increase to achieve this is 193 bytes.	vor 16 Jahren
Stefan Hajnoczi	fe79edfc3d	[GDB] Remove unused DR6 debug register variable	vor 16 Jahren
Stefan Hajnoczi	3715c8c721	[GDB] Zero-extend 16-bit segment registers When the 16-bit segment registers are accessed using 32-bit instructions the high order bytes are undefined on older CPUs. We now explicitly zero the high order bytes when snapshotting the CPU state. This ensures that the GDB stub reports consistent values for the segment registers.	vor 16 Jahren
Stefan Hajnoczi	5504fa9047	[GDB] Add copyright header for gdbmach.c	vor 16 Jahren
Stefan Hajnoczi	19386ec2c8	[GDB] Add watch and rwatch hardware watchpoints	vor 16 Jahren
Stefan Hajnoczi	04bc50f025	[GDB] Add GDB stub for remote debugging See http://etherboot.org/wiki/dev/gdbstub for documentation.	vor 16 Jahren
Stefan Hajnoczi	842165ef76	[GDBSYM] Remove unused gdbsym.c The GDBSYM config.h option was an attempt at QEMU GDB debugging. I have removed the code since it is unused and may confuse people wanting to use the GDB stub.	vor 16 Jahren
Alexey Zaytsev	4006d229e5	Introduce the new timer subsystem. Timer subsystem initialization code in core/timer.c Split the BIOS and RTDSC timer drivers from i386_timer.c Split arch/i386/firmware/pcbios/bios.c into the RTSDC timer driver and arch/i386/core/nap.c Split the headers properly: include/unistd.h - delay functions to be used by the gPXE core and drivers. include/gpxe/timer.h - the fimer subsystem interface to be used by the timer drivers and currticks() to be used by the code gPXE subsystems. include/latch.h - removed include/timer.h - scheduled for removal. Some driver are using currticks, which is only for core subsystems. Signed-off-by: Alexey Zaytsev <alexey.zaytsev@gmail.com>	vor 16 Jahren
Holger Lubitz	7815474495	Revert "malloc attribute changes" wasn't meant for my local "master" branch ;) This reverts commit 373022108b.	vor 17 Jahren
Holger Lubitz	373022108b	malloc attribute changes	vor 17 Jahren
Michael Brown	4ce8d61a5c	Import various libgcc functions from syslinux. Experimentation reveals that gcc ignores -mrtd for the implicit arithmetic functions (e.g. __udivdi3), but not for the implicit memcpy() and memset() functions. Mark the implicit arithmetic functions with __attribute__((cdecl)) to compensate for this. (Note: we cannot mark with with __cdecl, because we define __cdecl to incorporate regparm(0) as well.)	vor 17 Jahren
Michael Brown	f62d6486d8	GCC's optimiser seems to screw up if this is left static...	vor 17 Jahren
Michael Brown	a6a1052096	Applied a modified version of holger's regparm patches.	vor 17 Jahren
Holger Lubitz	0ae6c53bd9	Revert "make __udivmoddi4 static" - gcc links to it implicitly This reverts commit 9e7b165017.	vor 17 Jahren
Holger Lubitz	9e7b165017	make __udivmoddi4 static	vor 17 Jahren
Michael Brown	dc52db4920	Removed dead code identified by symcheck	vor 17 Jahren
Michael Brown	6d2e4e719c	Move uninitialised .data16 variables to .bss16; saves around 2000 bytes of useless zeroes in the final image.	vor 17 Jahren
Michael Brown	adf192f566	Shrink cpu.c and render it useful for our purposes.	vor 17 Jahren
Michael Brown	e330db3c74	Dead code removal. Kill off use of etherboot.h outside drivers/net.	vor 17 Jahren
Michael Brown	4e14b020a5	Master IRQ should be EOIed first, I think.	vor 17 Jahren
Michael Brown	fbda4837b0	Allocate heap at first usage, rather than assuming we can fit it in below _text. This should help with the gPXE-on-gPXE-via-PXE case.	vor 17 Jahren
Michael Brown	89349d7fad	Separated out initialisation functions from startup/shutdown functions.	vor 17 Jahren
Marty Connor	9b3c4e4d79	Warnings purge: src/arch/i386, src/core/disk.c, ramdisk, autoboot	vor 17 Jahren
Michael Brown	fae10a7ca1	We don't actually use the reset functions anywhere, and nothing really provides them.	vor 17 Jahren
Michael Brown	e42eba4af4	Use a common base-memory packet buffer for DHCP construction (as used by PXE and NBI) and UNDI packets (as used by undinet and UNDI).	vor 17 Jahren
Michael Brown	d5451d210c	Add ability to resolve relative symbols as well as locate absolute ones.	vor 17 Jahren
Michael Brown	8f6a4e8140	Add gdbsym.c object to help with running gdb-to-qemu	vor 17 Jahren

Michael Brown	b3b6b25aeb	Handle (64-bit) / (32-bit) = (64-bit), i.e. one step beyond that provided by the divl instruction.	vor 17 Jahren
Michael Brown	73b09ecba6	Use stdio.h instead of vsprintf.h	vor 17 Jahren
Michael Brown	bd95927386	Accelerate memcpy() by around 32% on large, dword-aligned copies.	vor 17 Jahren
Michael Brown	544fa25928	Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously reflect the fact that they allocate and deallocate user memory (i.e. things reached through a userptr_t).	vor 17 Jahren
Michael Brown	77d280968a	Obsoleted by arch/i386/image/multiboot.c	vor 17 Jahren
Michael Brown	644f3674e6	Obsolete for some time	vor 17 Jahren

Michael Brown	7ad1c2eaa8	Removed the Etherboot-specific ELF-image code and replaced it with a generic ELF loader, to be used by the multiboot code.	vor 17 Jahren
Michael Brown	c980cdd0aa	Move memmap.h out of arch/i386; it no longer contains anything architecture-dependent and is needed by the ELF code.	vor 17 Jahren
Michael Brown	e2dcd05b67	Update buffer-handling code to enable expandable buffers.	vor 17 Jahren
