[kvm-devel] [PATCH 0 of 6] Enhance PowerPC unit tests
These patches create libcflat for PowerPC and allow testcases to communicate with kvmctl via MMIO. They culminate in a C testcase that returns an error code through kvmctl to the shell. The x86 Makefiles looked hairy enough that I didn't want to mess with them, but it should be fairly easy to convert x86 to use the new test/lib/ files. 16 files changed, 436 insertions(+), 130 deletions(-) user/Makefile | 15 +++- user/config-powerpc.mak | 65 + user/config-x86-common.mak|6 ++- user/iotable.c| 53 ++ user/iotable.h| 40 ++ user/main-ppc.c | 65 + user/main.c | 52 + user/test/lib/libcflat.h | 37 + user/test/lib/panic.c | 13 +++ user/test/lib/powerpc/44x/map.c | 51 + user/test/lib/powerpc/44x/tlbwe.S | 50 ++-- user/test/lib/powerpc/io.c| 35 +++ user/test/lib/printf.c| 21 +-- user/test/lib/string.c|2 - user/test/powerpc/cstart.S| 38 + user/test/powerpc/exit.c | 23 + - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [kvm-devel] [PATCH] add acpi powerbutton support
Avi Kivity wrote: I think we need to go back to active low pci irqs, and to have no-ioapic working we need to insert an inverter between the pci irq links and the pic. I base this on the following: - piix doesn't contain an ioapic, so the actual lines must be active low - the piix pic elcr is documented as active-high for level-triggered irqs Okay, this is likely right as I was able to shutdown both Windows and Linux with the following: No, it's wrong. I found a piix4 acpi spec update that says that the SCI interrupt is hardwired to IRQ9 and is active high. Linux knows about this and ignores the pci irq config for this function. With the following changes - change acpi sci interrupt to be hardwired to irq9 - remove irq 9 from acpi dsdt (since qemu can't mix isa irqs and pci irqs correctly) - change the madt interrupt source override structure size to 10 (it was 12, which caused Windows to ignore it) - advertise the sci interrupt as tied to irq 9 in the fadt (instead of consulting the false pci config) both Windows and Linux are happy. I was even able to drop the forced pci irq enabling hack. I'll push those changes tomorrow morning. They are especially important with the acpi-based cpu and device hotplug that is brewing. -- Any sufficiently difficult bug is indistinguishable from a feature. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [kvm-devel] 2.6.24-rc8-mm1 (KVM build issues)
* Andrew Morton [EMAIL PROTECTED] [2008-01-17 02:35:14]:
- kvm probably doesn't work properly because I couldn't be bothered fixing
the conflicts between git-kvm and the driver tree
Hi, Andrew,
The following changes got KVM up and running for me
This patch fixes the kvm build on 2.6.24-rc8-mm1. First of all, it enables
the KVM build, the second fix moves kset_set_name to the .name member.

Re: [kvm-devel] [PATCH] KVM simplified virtio balloon driver
Rusty Russell wrote: After discussions with Anthony Liguori, it seems that the virtio balloon can be made even simpler. Here's my attempt. Since the balloon requires Guest cooperation anyway, there seems little reason to force it to tell the Host when it wants to reuse a page. It can simply fault it in. Faulting is synchronous, while deflating is (or can be made) asynchronous. If the host needs to do some work to get the memory, the guest will be slowed down considerably. If we have explicit deflate, the host can call madvise(MADV_WILLNEED) or actually touch the pages before the guest accesses them. -- Any sufficiently difficult bug is indistinguishable from a feature. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [kvm-devel] [PATCH] KVM simplified virtio balloon driver
Anthony Liguori wrote: It would be very useful too to write vb-num_pages into the config space whenever it was updated. This way, the host can easily keep track of where the guest is at in terms of ballooning. OTOH it's currently pretty obvious (and usually fatal) if the guest has trouble meeting the balloon requirements. A serious host needs a way of detecting stress in the guest anyway, which this doesn't offer until it's too late... The question I'm interested in answering though is not if but when. I would like to know when the guest has reached it's target. Yes. We don't want to activate the RSS controller immediately; give the guest some time to adjust voluntarily. -- Any sufficiently difficult bug is indistinguishable from a feature. - This SF.net email is sponsored by: Microsoft Defy all challenges.
