The source code will still be under some version control so it seems much better to simply keep it in the same project as all the other source code that is related. //Peter

I'm okay with the approach (two SSDTs selected by cpu count). The build changes don't look right (15.c is too cryptic). However, more importantly, I want to see where we end up going with the qemu/seabios acpi interface discussion before committing this. -Kevin

[PATCH 0/8] seabios: pci: multi pci bus support
by Isaku Yamahata 18 Jun '10

18 Jun '10

This patch set allows seabios to initialize multi pci bus and 64bit BAR. Currently seabios is able to initialize only pci root bus. However multi pci bus support is wanted because - more pci bus is wanted in qemu for many slots - pci express support is commin in qemu which requires multi pci bus. those patches on Qemu part are under way, though. Isaku Yamahata (8): seabios: pci: introduce foreachpci_in_bus() helper macro. seabios: pciinit: factor out pci bar region allocation logic. seabios: pciinit: make pci memory space assignment 64bit aware. seabios: pciinit: make pci bar assigner preferchable memory aware. seabios: pciinit: factor out bar offset calculation. seabios: pciinit: make bar offset calculation pci bridge aware. seabios: pciinit: pci bridge bus initialization. seabios: pciinit: initialize pci bridge filtering registers. src/pci.c | 30 ++++++ src/pci.h | 11 ++ src/pciinit.c | 310 ++++++++++++++++++++++++++++++++++++++++++++++++-------- 3 files changed, 306 insertions(+), 45 deletions(-)

[PATCH] acpi: add option, load_header, to -acpitable in order to load acpi header.
by Isaku Yamahata 15 Jun '10

15 Jun '10

This patch adds load_header option to -acpitable in order to load acpi table which includes acpi header. With this option and with seabios patches, alternative dsdt table can be passed to BIOS. Also fix potential buffer overflow. There is no guarantee that file size remains same when loading.
