Added ACPI SLIC table
by Arseny Klimovsky 21 Jun '10

21 Jun '10

Hello, in some cases Microsoft OEM licence can be used in virtual machine legally. http://www.microsoft.com/windowsserver2008/en/us/licensing-datacenter.aspx For Windows 7 it is not clear, but possibly it is legal. To make in technically possible, one should use its ACPI SLIC table from original BIOS in virtual BIOS. I've created a patch for some versions (including latest stable), it can be easily cherry-picked in master. http://gitorious.org/seabios/seabios Of course, the patch does not … [View More]

BTW, my other comments/questions aside, the patch series looks good to me. -Kevin

Re: [SeaBIOS] [PATCH 1/8] seabios: pci: introduce foreachpci_in_bus() helper macro.

Instead of introducing pci_next_in_bus(), can't we just use the existing pci_next() call? Something like: #define foreachpci_in_bus(BDF, MAX, BUS) \ for (MAX=(BUS + 0x0100), BDF = … [View More]

Re: [SeaBIOS] [PATCH] KVM vcpu hotplug seabios infrastructure
by Isaku Yamahata 21 Jun '10

Hi Jison. Can you check the changeset of 12cbb43b9dc8a16f712188cb308a0eb0321f3e20 and update Makefile changes? The rule for acpi-ssdt-15.hex and acpi-ssdt-anycpu.hex seems same, so it can be combined into a single generic rule. The rules removes the files at the last, but it would be more reliable to use Makefile intermediate and let make to remove them automatically.

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

[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. … [View More]
