SeaBIOS clears RAM between we write our -kernel image to RAM and the int19 handler gets triggered. So in order to work around that, I sat down and implemented Avi's suggestion of "downloading" all blobs in runtime from the fw_cfg interface Thanks to glommer who talked me into doing it ;-). Alexa

[Qemu-devel] [PATCH 5/6] Convert linux bootrom to external rom and fw_cfg

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

[Qemu-devel] [PATCH 3/6] Convert multiboot to fw_cfg backed data storage

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 pat

[Qemu-devel] [PATCH 2/6] Introduce copy_rom

[Qemu-devel] [PATCH 1/6] Make fw_cfg interface 32-bit aware

The fw_cfg interface can only handle up to 16 bits of data for its streams. While that isn't too much of a problem when handling integers, we would like to stream full kernel images over that interface! So let's extend it to 32 bit length variables. Signed-off-by: Alexander Graf --- hw/fw_cfg.c

[Qemu-devel] [PATCH 4/6] Move common option rom code to header file

[Qemu-devel] [PATCH 07/11] Add a lexer for JSON

Our JSON parser is a three stage parser. The first stage tokenizes the stream into a set of lexical tokens. Since the lexical grammar is regular, we can use a finite state machine to model it. The state machine will emit tokens as they are identified. Signed-off-by: Anthony Liguori --- Makefi
