2010-01-08linuxboot: fix gdt address calculationAvi Kivity1-2/+3
The gdt address calculation in linuxboot.bin is broken in two ways: first it loads %cs into %eax, but that instruction leaves the high bits of %eax undefined and we did not clear them. Secondly, we completely ignore the incorrect %eax, and use the undefined %ebx instead. With these issues fixed, linuxboot works again.

2010-01-08Use vpath directivePaolo Bonzini1-1/+2
The vpath directive has two advantages over the VPATH variable: 1) it allows to skip searching of .o files; 2) the default semantics are to append to the vpath, so there is no confusion between "VPATH=xyz" and "VPATH+=xyz". Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.

2009-12-03Make -kernel for linux work with bochsbiosAlexander Graf1-5/+5
While trying to run -kernel with -bios pc-bios/pcbios.bin, I realized that I was actually writing data to %es, but only set up %ds to a 32-bit segment we want to write to. So at the end of the day the data hasn't actually been copied. Oops. So here's a fix to set ES instead of DS, which makes -kernel work with BOCHS bios again (and actually makes the code do the correct thing)!

2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf3-1/+141
We already have a working multiboot implementation that uses fw_cfg to get its kernel module etc. data in int19 runtime now. So what's missing is a working linux boot option rom. While at it I figured it would be a good idea to take the opcode generator out of pc.c and instead use a proper option rom, like we do with multiboot. So here it is - an fw_cfg using option rom for -kernel with linux! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Move common option rom code to header fileAlexander Graf2-76/+110
We will have a linux boot option rom soon, so let's take all functionality that might be useful for both to a header file that both roms can include. That way we only have to write fw_cfg access code once. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Convert multiboot to fw_cfg backed data storageAlexander Graf1-17/+60
Right now we load the guest kernel to RAM, fire off the BIOS, hope it doesn't clobber memory and run an option rom that jumps into the kernel. That breaks with SeaBIOS, as that clears memory. So let's read all kernel, module etc. data using the fw_cfg interface when in the int19 handler. This patch implements said mechanism for multiboot.

2009-11-12eepro100: Fix boot ROM supportStefan Weil1-0/+0
* Rename pxe-eepro100.bin to pxe-i82559er.bin. The other devices supported by eepro100.c need additional pxe boot ROM images. * Call rom_add_option during initialisation. The code won't work with two or more different eepro100 devices, because it only adds one option ROM, but this use case is perhaps never needed. Using this patch, model=i82559er at least works partially. For full support, more eepro100 patches are needed (will follow later, can be fetched from ar7 branch of QEMU).
