2014-08-14pci: Use bus master address space for delivering MSI/MSI-X messagesJan Kiszka
The spec says (and real HW confirms this) that, if the bus master bit is 0, the device will not generate any PCI accesses. MSI and MSI-X messages fall among these, so we should use the corresponding address space to deliver them. This will prevent delivery if bus master support is disabled.

2014-08-07qga: Disable unsupported commands by defaultTomoki Sekiyama
Currently management softwares cannot know whether a qemu-ga command is supported or not on the running platform until they actually execute it. This patch disables unsupported commands at launch time of qemu-ga, so that management softwares can check whether they are supported from 'enabled' property of the result from 'guest-info' command.

2014-08-07qga: Add guest-get-fsinfo commandTomoki Sekiyama
Add command to get mounted filesystems information in the guest. The returned value contains a list of mountpoint paths and corresponding disks info such as disk bus type, drive address, and the disk controllers' PCI addresses, so that management layer such as libvirt can resolve the disk backends. For example, when `lsblk' result is: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 1G 0 disk `-sdb1 8:17 0 1024M 0 part `-vg0-lv0 253:1 0 1.4G 0 lvm /mnt/test sdc 8:32 0 1G 0 disk `-sdc1 8:33 0 512M 0 part `-vg0-lv0 253:1 0 1.4G 0 lvm /mnt/test vda 252:0 0 25G 0 disk `-vda1 252:1 0 25G 0 part / where sdb is a SCSI disk with PCI controller 0000:00:0a.0 and ID=1, sdc is an IDE disk with PCI controller 0000:00:01.1, and vda is a virtio-blk disk with PCI device 0000:00:06.0, guest-get-fsinfo command will return the following result: {"return": [{"name":"dm-1", "mountpoint":"/mnt/test", "disk":[ {"bus-type":"scsi","bus":0,"unit":1,"target":0, "pci-controller":{"bus":0,"slot":10,"domain":0,"function":0}}, {"bus-type":"ide","bus":0,"unit":0,"target":0, "pci-controller":{"bus":0,"slot":1,"domain":0,"function":1}}], "type":"xfs"}, {"name":"vda1", "mountpoint":"/", "disk":[ {"bus-type":"virtio","bus":0,"unit":0,"target":0, "pci-controller":{"bus":0,"slot":6,"domain":0,"function":0}}], "type":"ext4"}]} In Linux guest, the disk information is resolved from sysfs.

2014-08-07target-mips: Ignore unassigned accesses with KVMJames Hogan
MIPS registers an unassigned access handler which raises a guest bus error exception. However this causes QEMU to crash when KVM is enabled as it isn't called from the main execution loop so longjmp() gets called without a corresponding setjmp(). Until the KVM API can be updated to trigger a guest exception in response to an MMIO exit, prevent the bus error exception being raised from mips_cpu_unassigned_access() if KVM is enabled. The check is at run time since the do_unassigned_access callback is initialised before it is known whether KVM will be enabled. The problem can be triggered with Malta emulation by making the guest write to the reset region at physical address 0x1bf00000, since it is marked read-only which is treated as unassigned for writes.

2014-08-06cpu-exec: Print to console if the guest is lateSebastian Tanase
If the align option is enabled, we print to the user whenever the guest clock is behind the host clock in order for he/she to have a hint about the actual performance. The maximum print interval is 2s and we limit the number of messages to 100.

2014-08-06cpu-exec: Add sleeping algorithmSebastian Tanase
The goal is to sleep qemu whenever the guest clock is in advance compared to the host clock (we use the monotonic clocks). The amount of time to sleep is calculated in the execution loop in cpu_exec. At first, we tried to approximate at each for loop the real time elapsed while searching for a TB (generating or retrieving from cache) and executing it. We would then approximate the virtual time corresponding to the number of virtual instructions executed. The difference between these 2 values would allow us to know if the guest is in advance or delayed. However, the function used for measuring the real time (qemu_clock_get_ns(QEMU_CLOCK_REALTIME)) proved to be very expensive. We had an added overhead of 13% of the total run time. Therefore, we modified the algorithm and only take into account the difference between the 2 clocks at the begining of the cpu_exec function. During the for loop we try to reduce the advance of the guest only by computing the virtual time elapsed and sleeping if necessary. The overhead is thus reduced to 3%. Even though this method still has a noticeable overhead, it no longer is a bottleneck in trying to achieve a better guest frequency for which the guest clock is faster than the host one. As for the the alignement of the 2 clocks, with the first algorithm the guest clock was oscillating between -1 and 1ms compared to the host clock. Using the second algorithm we notice that the guest is 5ms behind the host, which is still acceptable for our use case. The tests where conducted using fio and stress. The host machine in an i5 CPU at 3.10GHz running Debian Jessie (kernel 3.12). The guest machine is an arm versatile-pb built with buildroot. Currently, on our test machine, the lowest icount we can achieve that is suitable for aligning the 2 clocks is 6. However, we observe that the IO tests (using fio) are slower than the cpu tests (using stress).

2014-08-06icount: Fix virtual clock start value on ARMSebastian Tanase
When using the icount option on ARM, the virtual clock starts counting at realtime clock but it should start at 0. The reason why the virtual clock starts at realtime clock is because the first time we call qemu_clock_warp (which calls icount_warp_rt) in tcg_exec_all, qemu_icount_bias (which is part of the virtual time computation mechanism) will increment by realtime - vm_clock_warp_start, with vm_clock_warp_start being 0 (see icount_warp_rt in cpus.c). By changing the value of vm_clock_warp_start from 0 to -1, the first time we call qemu_clock_warp which calls icount_warp_rt, we will return immediatly because icount_warp_rt first checks if vm_clock_warp_start is -1 and if it's the case it returns. Therefore, qemu_icount_bias will first be incremented by the value of a virtual timer deadline when the virtual cpu goes from active to inactive. The virtual time will start at 0 and increment based on the instruction counter when the vcpu is active or the qemu_icount_bias value when inactive.

2014-08-06backends: Introduce chr-testdevPaolo Bonzini
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.

2014-08-05vfio: Fix MSI-X vector expansionAlex Williamson
When new MSI-X vectors are enabled we need to disable MSI-X and re-enable it with the correct number of vectors. That means we need to reprogram the eventfd triggers for each vector. Prior to f4d45d47 vector->use tracked whether a vector was masked or unmasked and we could always pick the KVM path when available for unmasked vectors. Now vfio doesn't track mask state itself and vector->use and virq remains configured even for masked vectors. Therefore we need to ask the MSI-X code whether a vector is masked in order to select the correct signaling path. As noted in the comment, MSI relies on hardware to handle masking.

2014-08-01tap-bsd: implement a FreeBSD only version of tap_openRoger Pau Monne
The current behaviour of tap_open for BSD systems differ greatly from it's Linux counterpart. Since FreeBSD supports interface renaming and tap device cloning by opening /dev/tap, implement a FreeBSD specific version of tap_open that behaves like it's Linux counterpart. This is specially important for toolstacks that use Qemu (like Xen libxl), in order to have a unified behaviour across suported platforms.

2014-08-01xen: fix usage of ENODATARoger Pau Monne
ENODATA doesn't exist on FreeBSD, so ENODATA errors returned by the hypervisor are translated to ENOENT. Also, the error code is returned in errno if the call returns -1, so compare the error code with the value in errno instead of the value returned by the function.
