* Make -kernel for linux work with bochsbiosAlexander Graf2009-12-031-5/+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)!

* Convert linux bootrom to external rom and fw_cfgAlexander Graf2009-11-173-1/+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>
* Move common option rom code to header fileAlexander Graf2009-11-172-76/+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>
* Convert multiboot to fw_cfg backed data storageAlexander Graf2009-11-171-17/+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.

* eepro100: Fix boot ROM supportStefan Weil2009-11-121-0/+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).

* Multiboot support v5Alexander Graf2009-06-291-0/+209
| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements support for Multiboot on x86 for -kernel. Multiboot is a "new" approach to get rid of different bootloaders, providing a unified interface for the kernel. It supports command line options and kernel modules. The two probably best known projects using multiboot are Xen and GNU Hurd. This implementation should be mostly feature-complete. It is missing VBE extensions, but as no system uses them currently it does not really hurt. To use multiboot, specify the kernel as -kernel option. Modules should be given as -initrd options, seperated by a comma (,). -append also works. Please bear in mind that grub also does gzip decompression, which qemu does not do yet. To run existing images, please ungzip them first. The guest multiboot loader code is implemented as option rom using int 19. Parts of the work are based on efforts by Rene Rebe, who originally ported my code to int 19. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
