2010-12-11Change fw_cfg_add_file() to get full file path as a parameter.Gleb Natapov1-2/+2
Change fw_cfg_add_file() to get full file path as a parameter instead of building one internally. Two reasons for that. First caller may need to know how file is named. Second this moves policy of file naming out from fw_cfg. Platform may want to use more then two levels of directories for instance.

2009-12-18fw_cfg: add API for file transfer.Gerd Hoffmann1-2/+19
This patch adds a file transfer interface to fw_cfg. Intended to be used for passing non-pci option roms and vgabios to seabios. Namespace is modeled after the existing cbfs filesystem support in seabios. Reading the new FW_CFG_FILE_DIR entry returns a file list. Fields there are in network byte order (aka bigendian). aliguori: fix fw_cfg.h for multiboot.bin, add proper fw_cfg.h declarations, quiet fprintf() in fw_cfg.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf1-1/+7
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>
2009-11-17Convert multiboot to fw_cfg backed data storageAlexander Graf1-1/+4
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.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-1/+1
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.
