by Gerd Hoffmann 27 Sep '13

27 Sep '13

Hi, I plan to build the next release for the 1.7.2-stable branch, probably later this week or early next week. Three patches have been cherry-picked into the branch since 1.7.2.1 has been released: # git shortlog rel-1.7.3.1.. Gerd Hoffmann (3): apm: fix shutdown ahci: add missing check for allocation failure fix buildversion.sh Any other important fixes which should go into the next stable release? cheers, Gerd

Hi, I´m a newbie with respect to using CoreBoot and the seaBIOS payload. Can someone inform if SeaBIOS has support for IPMI System Boot Options commands ?

[PATCH] build: explicitly set rom size
by Gerd Hoffmann 24 Sep '13

24 Sep '13

Replace the automatic rom sizing with an explicit kconfig option. ROM changing size is a problem for qemu live migration, therefore an explicit size is prefered. Make the default rom size 256k, with the recent xhci support merge seabios doesn't fit into 128k any more.

[PATCH] build: move .config to $(OUT)
by Gerd Hoffmann 24 Sep '13

24 Sep '13

Place the .config file in the output directory. This makes it easier to have multiple output directories with different configurations as "make OUT=out-${config}/" will automatically switch to the correct configuration. It also allows to do parallel builds of different configurations. To simplify transition copy over the .config file in case there is one at the old location but not at the new location.

The size itself isn't the problem. live-migrating from a qemu version with a 128k seabios to a newer version with a larger bios is a problem though as that is a change in the virtual hardware while the machine is running. cheers, Gerd

[PATCH v3 0/5] seabios: load acpi tables from qemu
by Michael S. Tsirkin 23 Sep '13

23 Sep '13

This is the seabios code that adds support for loading acpi tables from QEMU. Kevin, I think I have addresses all your comments. In particular, in the end I dropped the new data field from the romfile structure. Please review and consider for merging.

[PATCH] fix buildversion.sh
by Gerd Hoffmann 23 Sep '13

23 Sep '13

Recent git versions place the submodule git repos into the .git/modules directory of the toplevel repo. In that case .git of the seabios tree isn't a directory, but a regular file, saying where the gitdir is. Extent the git check to also allow .git being a regular file, so buildversion.sh works correctly when called within the qemu submodule.
