2012-05-21msix: Introduce vector notifiersJan Kiszka
Vector notifiers shall be triggered by the MSI/MSI-X core whenever a relevant configuration change is programmed by the guest. In case of MSI-X, changes are reported when the effective mask (global && per-vector) alters its state. On unmask, the current vector configuration is included in the event report. This allows users - e.g. virtio-pci layer - to transfer this information to external MSI-X routing subsystems - like vhost + KVM in-kernel irqchip. This implementation only provides MSI-X support, but extension to MSI is feasible and will be provided later on when adding support for KVM PCI device assignment.

2012-05-16kvm: Introduce basic MSI support for in-kernel irqchipsJan Kiszka
This patch basically adds kvm_irqchip_send_msi, a service for sending arbitrary MSI messages to KVM's in-kernel irqchip models. As the original KVM API requires us to establish a static route from a pseudo GSI to the target MSI message and inject the MSI via toggling that virtual IRQ, we need to play some tricks to make this interface transparent. We create those routes on demand and keep them in a hash table. Succeeding messages can then search for an existing route in the table first and reuse it whenever possible. If we should run out of limited GSIs, we simply flush the table and rebuild it as messages are sent. This approach is rather simple and could be optimized further. However, latest kernels contains a more efficient MSI injection interface that will obsolete the GSI-based dynamic injection.

2012-05-02ATA: Allow WIN_SECURITY_FREEZE_LOCK as nopAlexander Graf
When using Windows 8 with an AHCI disk drive, it issues a blue screen. The reason is that WIN_SECURITY_FREEZE_LOCK / CFA_WEAR_LEVEL is not supported by our ATA implementation, but Windows expects it to be there. Since without security stuff implemented, the lock would be a nop anyway and CFA_WEAR_LEVEL already is treated as a nop, let's just allow the cmd for HD drives as well. That way Windows is happy.

2012-05-01Declare state directory in smb.confNikolaus Rath
The smb.conf generated by the userspace networking does not include a state directory directive. Samba therefore falls back to the default value. Since the user generally does not have write access to this path, smbd immediately crashes. The "state directory" option was added in Samba 3.4.0 (commit http://gitweb.samba.org/?p=samba.git;a=commit;h=7b02e05eb64f3ffd7aa1cf027d10a7343c0da757). This patch adds the missing option.

2012-05-01slirp: don't use "smb ports = 0" optionNikolaus Rath
The "smb ports = 0" option causes recent samba versions to crash. It was introduced in commit 157777ef3e with log message "Samba 3 support". However, a value of 0 has never been officially supported by smb and is also not necessary: if stdin is a socket, smb does not try to listen on any ports and uses just stdin. This is necessary to support inetd based operation (otherwise smbd would always fail when called from inetd, because inetd already listens on the SMB port). Since samba has supported inetd operation since pre-3.x, it should be safe to rely on this feature. I have tested it with Samba 3.6.4 -- communication works fine, and smbd is not listening on any ports. I suspect the "smb ports = 0" hack may have been introduced when someone tested the qemu generated samba config from the command line with "smbd -i" and found it to fail (because then stdin isn't a socket).

When trying to evaluate the size of the _host_ type size for olddev_t, we need to expose the host's pointer size, not the guest pointer size. This usage got introduced accidently in commit b754e4fc1.

2012-05-01ppce500_spin: Replace assert by hw_error (fixes compiler warning)Stefan Weil
The default case in function spin_read should never be reached, therefore the old code used assert(0) to abort QEMU. This does not work when QEMU is compiled with macro NDEBUG defined. In this case (and also when the compiler does not know that assert never returns), there is a compiler warning because of the missing return value.

2012-05-01pseries: Use the same interrupt swizzling for host bridges as p2p bridgesDavid Gibson
Currently the pseries PCI code uses a somewhat strange scheme of PCI irq allocation - one per slot up to a maximum that's greater than the usual 4. This scheme more or less worked, because we were able to tell the guest the irq mapping in the device tree, however it's a bit odd and may break assumptions in the future. Worse, the array used to construct the dev tree interrupt map was mis-sized, we got away with it only because it happened that our SPAPR_PCI_NUM_LSI value was greater than 7. This patch changes the pseries PCI code to use the same interrupt swizzling scheme as is standardized for PCI to PCI bridges. This makes for better consistency, deals better with any devices which use multiple interrupt pins and will make life easier in the future when we add passthrough of what may be either a host bridge or a PCI to PCI bridge. This won't break existing guests, because they don't assume a particular mapping scheme for host bridges, but just follow what we tell them in the device tree (also updated to match, of course). This patch also fixes the allocation of the irq map. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-05-01pseries: Implement automatic PAPR VIO address allocationDavid Gibson
PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary, "address" used as a token to the hypercalls which manipulate them. Currently the pseries machine code does an ok job of allocating these addresses when the legacy -net nic / -serial and so forth options are used but will fail to allocate them properly when using -device. Specifically, you can use -device if all addresses are explicitly assigned. Without explicit assignment, only one VIO device of each type (network, console, SCSI) will be assigned properly, any further ones will attempt to take the same address leading to a fatal error. This patch fixes the situation by adding a proper address allocator to the VIO "bus" code. This is used both by -device and the legacy options and default devices. Addresses can still be explicitly assigned with -device options if desired. This patch changes the (guest visible) numbering of VIO devices, but since their addresses are discovered using the device tree and already differ from the numbering found on existing PowerVM systems, this does not break compatibility.
