2012-08-06virtio: fix vhost handlingPaolo Bonzini3-10/+14
Commit b1f416aa8d870fab71030abc9401cfc77b948e8e breaks vhost_net because it always registers the virtio_pci_host_notifier_read() handler function on the ioeventfd, even when vhost_net.ko is using the ioeventfd. The result is both QEMU and vhost_net.ko polling on the same eventfd and the virtio_net.ko guest driver seeing inconsistent results: # ifconfig eth0 192.168.0.1 netmask 255.255.255.0 virtio_net virtio0: output:id 0 is not a head! To fix this, proceed the same as we do for irqfd: add a parameter to virtio_queue_set_host_notifier_fd_handler and in that case only set the notifier, not the handler.

2012-08-04Fixes related to processing of qemu's -numa optionChegu Vinod1-1/+2
The -numa option to qemu is used to create [fake] numa nodes and expose them to the guest OS instance. There are a couple of issues with the -numa option: a) Max VCPU's that can be specified for a guest while using the qemu's -numa option is 64. Due to a typecasting issue when the number of VCPUs is > 32 the VCPUs don't show up under the specified [fake] numa nodes. b) KVM currently has support for 160VCPUs per guest. The qemu's -numa option has only support for upto 64VCPUs per guest. This patch addresses these two issues. Below are examples of (a) and (b) a) >32 VCPUs are specified with the -numa option: /usr/local/bin/qemu-system-x86_64 \ -enable-kvm \ 71:01:01 \ -net tap,ifname=tap0,script=no,downscript=no \ -vnc :4 ...

2012-08-03megasas: static SAS addressesHannes Reinecke2-17/+49
This patch introduces a new property 'sas_address' which allows the user to specify the SAS address for the HBA. The default address is following the NAA locally assigned identifier format with the locally assigned address 0x525400 as used eg for the MAC addresses. The lower bytes are set to the pci address which will ensure uniqueness for the local machine. The port addresses are now calculated based on the magic number 0x1221 (which is found in real hardware, too) plus the device number.

2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell3-4/+4
For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.

Moving reset callback into cpu object from board level and resetting cpu at the end of x86_cpu_realize() will allow properly create cpu object during run-time (hotplug) without calling reset externaly. When reset over QOM hierarchy is implemented, reset callback should be removed. v2: - leave cpu_reset in pc_new_cpu() for now, it's to be cleaned up when APIC init is moved in cpu.c Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-08-01target-i386: move cpu halted decision into x86_cpu_resetIgor Mammedov3-13/+17
MP initialization protocol differs between cpu families, and for P6 and onward models it is up to CPU to decide if it will be BSP using this protocol, so try to model this. However there is no point in implementing MP initialization protocol in qemu. Thus first CPU is always marked as BSP. This patch: - moves decision to designate BSP from board into cpu, making cpu self-sufficient in this regard. Later it will allow to cleanup hw/pc.c and remove cpu_reset and wrappers from there. - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior described in Inted SDM vol 3a part 1 chapter 8.4.1 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP patch is based on Jan Kiszka's proposal: http://thread.gmane.org/gmane.comp.emulators.qemu/100806 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
