Subject: [Qemu-devel] [PATCH 0/6] Fix -kernel with SeaBIOS
Date: Wed, 11 Nov 2009 19:09:20 +0100 [thread overview]
Message-ID: <1257962966-22902-1-git-send-email-agraf@suse.de> (raw)
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 ;-).
Alexander Graf (6):
Make fw_cfg interface 32-bit aware
Introduce copy_rom
Convert multiboot to fw_cfg backed data storage
Move common option rom code to header file
Convert linux bootrom to external rom and fw_cfg
Add linuxboot to BLOBS
