2016-07-18vfio/pci: Hide ARI capabilityAlex Williamson
QEMU supports ARI on downstream ports and assigned devices may support ARI in their extended capabilities. The endpoint ARI capability specifies the next function, such that the OS doesn't need to walk each possible function, however this next function is relative to the host, not the guest. This leads to device discovery issues when we combine separate functions into virtual multi-function packages in a guest. For example, SR-IOV VFs are not enumerated by simply probing the function address space, therefore the ARI next-function field is zero. When we combine multiple VFs together as a multi-function device in the guest, the guest OS identifies ARI is enabled, relies on this next-function field, and stops looking for additional function after the first is found. Long term we should expose the ARI capability to the guest to enable configurations with more than 8 functions per slot, but this requires additional QEMU PCI infrastructure to manage the next-function field for multiple, otherwise independent devices. In the short term, hiding this capability allows equivalent functionality to what we currently have on non-express chipsets.

2016-07-18.travis.yml: Disable IRC build status updates from forksPranith Kumar
We want the travis build bot to post notifications on IRC only for the master qemu repository and not the various forks/branches of others. Currently there is no direct option to restrict the updates to one repository. This is being worked upon by the developers and tracked in https://github.com/travis-ci/travis-ci/issues/1094. Until such time, we can use the workaround as posted in ref. https://github.com/facebook/flow/pull/1822. This basically creates an ecrypted string which decrypts to qemu IRC channel only on "qemu/qemu" repo and not on the forks. This enables the build bot to notify the IRC only for the main repo.

2016-07-18linux-aio: prevent submitting more than MAX_EVENTSRoman Pen
Invoking io_setup(MAX_EVENTS) we ask kernel to create ring buffer for us with specified number of events. But kernel ring buffer allocation logic is a bit tricky (ring buffer is page size aligned + some percpu allocation are required) so eventually more than requested events number is allocated. From a userspace side we have to follow the convention and should not try to io_submit() more or logic, which consumes completed events, should be changed accordingly. The pitfall is in the following sequence: MAX_EVENTS = 128 io_setup(MAX_EVENTS) io_submit(MAX_EVENTS) io_submit(MAX_EVENTS) /* now 256 events are in-flight */ io_getevents(MAX_EVENTS) = 128 /* we can handle only 128 events at once, to be sure * that nothing is pended the io_getevents(MAX_EVENTS) * call must be invoked once more or hang will happen. */ To prevent the hang or reiteration of io_getevents() call this patch restricts the number of in-flights, which is now limited to MAX_EVENTS.

2016-07-18ppc: Yet another fix for the huge page support detection mechanismThomas Huth
Commit 86b50f2e1bef ("Disable huge page support if it is not available for main RAM") already made sure that huge page support is not announced to the guest if the normal RAM of non-NUMA configurations is not backed by a huge page filesystem. However, there is one more case that can go wrong: NUMA is enabled, but the RAM of the NUMA nodes are not configured with huge page support (and only the memory of a DIMM is configured with it). When QEMU is started with the following command line for example, the Linux guest currently crashes because it is trying to use huge pages on a memory region that does not support huge pages: qemu-system-ppc64 -enable-kvm ... -m 1G,slots=4,maxmem=32G -object \ memory-backend-file,policy=default,mem-path=/hugepages,size=1G,id=mem-mem1 \ -device pc-dimm,id=dimm-mem1,memdev=mem-mem1 -smp 2 \ -numa node,nodeid=0 -numa node,nodeid=1 To fix this issue, we've got to make sure to disable huge page support, too, when there is a NUMA node that is not using a memory backend with huge page support.

2016-07-18spapr: Ensure CPU cores are added contiguously and removed in LIFO orderBharata B Rao
If CPU core addition or removal is allowed in random order leading to holes in the core id range (and hence in the cpu_index range), migration can fail as migration with holes in cpu_index range isn't yet handled correctly.

This ioctl() call to VFIO_IOMMU_SPAPR_TCE_REMOVE was left over from an earlier version of the code and has since been folded into vfio_spapr_remove_window(). It wasn't caught because although the argument structure has been removed, the libc function remove() means this didn't trigger a compile failure. The ioctl() was also almost certain to fail silently and harmlessly with the bogus argument, so this wasn't caught in testing.

2016-07-18spapr: fix core unplug crashGreg Kurz
If the host has 8 threads/core and the guest is started with: -smp cores=1,threads=4,maxcpus=12 It is possible to crash QEMU by doing: (qemu) device_add host-spapr-cpu-core,core-id=16,id=foo (qemu) device_del foo Segmentation fault This happens because spapr_core_unplug() assumes cpu_dt_id == core_id. As long as cpu_dt_id is derived from the non-table cpu_index, this is only true when you plug cores with contiguous ids. It is safer to be consistent: the DR connector was created with an index that is immediately written to cc->core_id, and spapr_core_plug() also relies on cc->core_id.

this is the first step in reducing the brk heap fragmentation created by the map->nodes memory allocation. Since the introduction of RCU the freeing of the PhysPageMaps is delayed so that sometimes several hundred are allocated at the same time. Even worse the memory for map->nodes is allocated and shortly afterwards reallocated. Since the number of nodes it grows to in the end is the same for all PhysPageMaps remember this value and at least avoid the reallocation. The large number of simultaneous allocations (about 450 x 70kB in my configuration) has to be addressed later.

2016-07-15vnc-tight: fix regression with libxenstorePeter Lieven
commit 095497ff added thread local storage for the color counting palette. Unfortunately, a VncPalette is about 7kB on a x86_64 system. This memory is reserved from the stack of every thread and it exhausted the stack space of a libxenstore thread. Fix this by allocating memory only for the VNC encoding thread.

2016-07-15vnc-enc-tight: fix off-by-one bugHerongguang (Stephen)
In tight_encode_indexed_rect32, buf(or src)’s size is count. In for loop, the logic is supposed to be that i is an index into src, i should be incremented when incrementing src. This is broken when src is incremented but i is not before while loop, resulting in off-by-one bug in while loop.

2016-07-15vnc: make sure we finish disconnectGerd Hoffmann
It may happen that vnc connections linger in disconnecting state forever because VncState happens to be in a state where vnc_update_client() exists early and never reaches the vnc_disconnect_finish() call at the bottom of the function. Fix that by doing an additinal check at the start of the function. https://bugzilla.redhat.com/show_bug.cgi?id=1352799 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 1468405280-2571-1-git-send-email-kraxel@redhat.com

2016-07-14ast2400: externalize revision numbersCédric Le Goater
AST2400_A0_SILICON_REV is defined twice. Fix this by including the definition in the header file as well as the routine to check if a silicon revision is supported. It will useful to reuse in other controllers. Let's add also AST2500_A0_SILICON_REV for future use.

2016-07-14ast2400: pretend DMAs are done for U-bootCédric Le Goater
U-boot does SPI timing calibration using DMA tranfers. To let the initialization continue, we fake success by setting the DMA status of the Interrupt Control Register. For the moment, DMA support is not required as it is not used in normal operation.
