Bootorder file question regarding USB hubs/devices
by Dave Frodin 02 Sep '12

02 Sep '12

Previously (before fetching the latest seabios/master) our bootorder file looked like this /pci@i0cf8/usb@12,2/*@4 /pci@i0cf8/usb@12,2/*@5 /pci@i0cf8/usb@12,2/*@3 /pci@i0cf8/usb@12,2/*@2 /pci@i0cf8/usb@12,2/*@1 /pci@i0cf8/usb@12,2/*@0 Now it looks like this. This also includes devices plugged into hubs on two of the ports. (Thank you to whoever got hubs working) /pci@i0cf8/usb@12,2/storage@5/*@0/*@0,0 /pci@i0cf8/usb@12,2/storage@4/*@0/*@0,0 /pci@i0cf8/usb@12,2/storage@3/*@0/*@0,0 /pci@i0cf8/usb@12,2/storage@2/*@0/*@0,0 /pci@i0cf8/usb@12,2/storage@1/*@0/*@0,0 /pci@i0cf8/usb@12,2/storage@0/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@4/storage@1/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@4/storage@2/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@4/storage@3/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@4/storage@4/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@1/storage@1/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@1/storage@2/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@1/storage@3/*@0/*@0,0 /pci@i0cf8/usb@12,2/hub@1/storage@4/*@0/*@0,0 Is there an easier/generic way to condense this down?

[PATCH] acpi: LNKS is not needed
by Paolo Bonzini 02 Sep '12

02 Sep '12

LNKS is a bit strange in that it reuses the same PIIX register as LNKA, but has a different interrupt. This means that the _CRS it returns will not be one of the possible resources from _PRS. This shows up in the Linux boot logs as ACPI: PCI Interrupt Link [LNKS] (IRQs 9) *0 Instead of that, we can simply use a hardwired interrupt index.

[PATCH v2 0/6] Build PCI hotplug SSDT from a single template
by Paolo Bonzini 02 Sep '12

02 Sep '12

More than 1kb of data is taken by the 32 copies of the PCI hotplug SSDT methods. We can build them from a single template like we do for CPUs. This series does exactly this. Patches 1 prepares for the change, by moving other pieces of ssdt-pcihd.dsl out of the way. Patch 2 is also a simple rename and patch 3 fixes a bug in acpi_extract. Patches 4 to 6 finally do the movement. v1->v2: document computation of length (patch 1, Igor) build PCNT dynamically (Kevin) Paolo Bonzini (6): acpi: move s3/s4/s5 to build_ssdt acpi: rename Processor SSDT constants acpi_extract: fix off-by-one acpi_extract: detect DeviceOp acpi: build PCNT dynamically acpi: build PCI hotplug devices from a single template Makefile | 2 +- src/acpi.c | 218 +++++++++++++++++++++++++++---------------------- src/ssdt-pcihp.dsl | 124 +++------------------------- src/ssdt-susp.dsl | 41 ++++++++++ tools/acpi_extract.py | 30 ++++++- 5 files changed, 203 insertions(+), 212 deletions(-) create mode 100644 src/ssdt-susp.dsl -- 1.7.10.4

[PATCH] Makefile: delete output on error
by Michael S. Tsirkin 02 Sep '12

02 Sep '12

I had a disk full condition and a partial hex file got generated. Following make failed trying to use it. We can make build a bit more robust by instructing make to remove output files on error.

This patch addresses some feedback sent by Laszlo[1] on the non-contiguous APIC ID patches I have sent recently. - (1 << 31) is undefined for 32-bit signed ints - Use !! on the returned value, so the function return value can be an int without a unsigned -> signed conversion [] http://article.gmane.org/gmane.comp.emulators.qemu/162163 Cc: Laszlo Ersek <lersek(a)redhat.com> Signed-off-by: Eduardo Habkost <ehabkost(a)redhat.com> --- src/smp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/smp.c b/src/smp.c index 3c36f8c..4975412 100644 --- a/src/smp.c +++ b/src/smp.c @@ -77,7 +77,7 @@ ASM16( int apic_id_is_present(u8 apic_id) { - return FoundAPICIDs[apic_id/32] & (1 << (apic_id % 32)); + return !!(FoundAPICIDs[apic_id/32] & (1ul << (apic_id % 32))); } // find and initialize the CPUs by launching a SIPI to them -- 1.7.11.4
