Patch set updated for coreboot: 73bd69c qemu: load acpi tables from fw_cfg.
by Gerd Hoffmann 13 Nov '13

13 Nov '13

Gerd Hoffmann (kraxel(a)redhat.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4040 -gerrit commit 73bd69cdf5e3311903a66c5a5ef081bdeb29798c Author: Gerd Hoffmann <kraxel(a)redhat.com> Date: Thu Jul 25 15:59:07 2013 +0200 qemu: load acpi tables from fw_cfg. Starting with release 1.7 qemu provides acpi tables via fw_cfg. Main advantage is that new (virtual) hardware which needs acpi support JustWorks[tm] without having to patch & update the firmware (seabios, coreboot, ...) accordingly. So if we find acpi tables in fw_cfg try loading them, otherwise fallback to the builtin acpi tables.

New patch to review for coreboot: 3fdf58f board_status.sh: trivial cosmetic changes toward the end

David Hendricks (dhendrix(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4051 -gerrit commit 3fdf58f5d166e937ec9637cf55f9ae804fafdeae Author: David Hendricks <dhendrix(a)chromium.org> Date: Tue Nov 12 18:17:19 2013 -0800 board_status.sh: trivial cosmetic changes toward the end This moves an ugly comment closer to where it is applicable and also adds a visual break between the commands which gather data and the part of the script that finishes up. I'm usually not fan of banner comments, but it seemed to help in my totally subjective opinion. I was thinking about how to break the part that uploads results into a separate function, but there are enough variables that are re-used from earlier parts that the tradeoff probably isn't worth it.

13 Nov '13

David Hendricks (dhendrix(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4039 -gerrit commit 4f32651e0a9653a66fc961a1919651d6d0a107e8 Author: David Hendricks <dhendrix(a)chromium.org> Date: Mon Nov 11 18:44:05 2013 -0800 Updates to the board status script This is the first major re-work for the board status script. Summary: - Added a command to the getrevision.sh script to retrieve tagged revision. - Results are placed in a dynamically generated temporary location. This makes it easy to do multiple trial runs and avoids polluting the coreboot directory. - Results are stored in a directory with the following form: <vendor>/<mainboard>/<tagged_revision>/<timestamp>/ Vendor and mainboard are obtained from CONFIG_MAINBOARD_DIR so that hierarchy is consistent between coreboot and board-status. - The results directory is used as the commit message. - board-status repository is checked out automatically if results are to be uploaded. TODO: - Add ability to run commands which may fail. Currently we assume any failure should terminate the script, but some commands can be made optional. Successfully uploaded first result to board-status repository. See http://review.coreboot.org/gitweb?p=board-status.git;a=summary .
