2015-10-09update-linux-headers: Rename SW_MAX to SW_MAX_Markus Armbruster
The next commit will compile hw/input/virtio-input.c and hw/input/virtio-input-hid.c even when CONFIG_LINUX is off. These files include both "include/standard-headers/linux/input.h" and <windows.h> then. Doesn't work, because both define SW_MAX. We don't actually use it. Patch input.h to define SW_MAX_ instead.

2015-10-07tcg: Adjust CODE_GEN_AVG_BLOCK_SIZERichard Henderson
At present, the "average" guestimate of TB size is way too small, leading to many unused entries in the pre-allocated TB array. For a guest with 1GB ram, we're currently allocating 256MB for the array. Survey arm, alpha, aarch64, ppc, sparc, i686, x86_64 guests running on x86_64 and ppc64 hosts and select a new average.

2015-10-07tcg: Check for overflow via highwater markRichard Henderson
We currently pre-compute an worst case code size for any TB, which works out to be 122kB. Since the average TB size is near 1kB, this wastes quite a lot of storage. Instead, check for overflow in between generating code for each opcode. The overhead of the check isn't measurable and wastage is minimized.

2015-10-05memory: Allow replay of IOMMU mapping notificationsDavid Gibson
When we have guest visible IOMMUs, we allow notifiers to be registered which will be informed of all changes to IOMMU mappings. This is used by vfio to keep the host IOMMU mappings in sync with guest IOMMU mappings. However, unlike with a memory region listener, an iommu notifier won't be told about any mappings which already exist in the (guest) IOMMU at the time it is registered. This can cause problems if hotplugging a VFIO device onto a guest bus which had existing guest IOMMU mappings, but didn't previously have an VFIO devices (and hence no host IOMMU mappings). This adds a memory_region_iommu_replay() function to handle this case. It replays any existing mappings in an IOMMU memory region to a specified notifier. Because the IOMMU memory region doesn't internally remember the granularity of the guest IOMMU it has a small hack where the caller must specify a granularity at which to replay mappings. If there are finer mappings in the guest IOMMU these will be reported in the iotlb structures passed to the notifier which it must handle (probably causing it to flag an error). This isn't new - the VFIO iommu notifier must already handle notifications about guest IOMMU mappings too short for it to represent in the host IOMMU.

2015-10-05vfio: Check guest IOVA ranges against host IOMMU capabilitiesDavid Gibson
The current vfio core code assumes that the host IOMMU is capable of mapping any IOVA the guest wants to use to where we need. However, real IOMMUs generally only support translating a certain range of IOVAs (the "DMA window") not a full 64-bit address space. The common x86 IOMMUs support a wide enough range that guests are very unlikely to go beyond it in practice, however the IOMMU used on IBM Power machines - in the default configuration - supports only a much more limited IOVA range, usually 0..2GiB. If the guest attempts to set up an IOVA range that the host IOMMU can't map, qemu won't report an error until it actually attempts to map a bad IOVA. If guest RAM is being mapped directly into the IOMMU (i.e. no guest visible IOMMU) then this will show up very quickly. If there is a guest visible IOMMU, however, the problem might not show up until much later when the guest actually attempt to DMA with an IOVA the host can't handle. This patch adds a test so that we will detect earlier if the guest is attempting to use IOVA ranges that the host IOMMU won't be able to deal with. For now, we assume that "Type1" (x86) IOMMUs can support any IOVA, this is incorrect, but no worse than what we have already. We can't do better for now because the Type1 kernel interface doesn't tell us what IOVA range the IOMMU actually supports. For the Power "sPAPR TCE" IOMMU, however, we can retrieve the supported IOVA range and validate guest IOVA ranges against it, and this patch does so.

2015-10-05vfio: Remove unneeded union from VFIOContainerDavid Gibson
Currently the VFIOContainer iommu_data field contains a union with different information for different host iommu types. However: * It only actually contains information for the x86-like "Type1" iommu * Because we have a common listener the Type1 fields are actually used on all IOMMU types, including the SPAPR TCE type as well In fact we now have a general structure for the listener which is unlikely to ever need per-iommu-type information, so this patch removes the union. In a similar way we can unify the setup of the vfio memory listener in vfio_connect_container() that is currently split across a switch on iommu type, but is effectively the same in both cases. The iommu_data.release pointer was only needed as a cleanup function which would handle potentially different data in the union. With the union gone, it too can be removed.

ABM is only implemented as a single instruction set by AMD; all AMD processors support both instructions or neither. Intel considers POPCNT as part of SSE4.2, and LZCNT as part of BMI1, but Intel also uses AMD's ABM flag to indicate support for both POPCNT and LZCNT. It has to be added to Haswell and Broadwell because Haswell, by adding LZCNT, has completed the ABM.

2015-09-24oslib-win32: only provide localtime_r/gmtime_r if missingDaniel P. Berrange
The oslib-win32 file currently provides a localtime_r and gmtime_r replacement unconditionally. Some versions of Mingw-w64 would provide crude macros for localtime_r/gmtime_r which QEMU takes care to disable. Latest versions of Mingw-w64 now provide actual functions for localtime_r/gmtime_r, but with a twist that you have to include unistd.h or pthread.h before including time.h. By luck some files in QEMU have such an include order, resulting in compile errors: CC util/osdep.o In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:77:12: error: redundant redeclaration of 'gmtime_r' [-Werror=redundant-decls] struct tm *gmtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:272:107: note: previous definition of 'gmtime_r' was here In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:79:12: error: redundant redeclaration of 'localtime_r' [-Werror=redundant-decls] struct tm *localtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:269:107: note: previous definition of 'localtime_r' was here This change adds a configure test to see if localtime_r exits, and only enables the QEMU impl if missing. We also re-arrange qemu-common.h try attempt to guarantee that all source files get unistd.h before time.h and thus see the localtime_r/gmtime_r defs.

2015-09-24qemu-thread: add a fast path to the Win32 QemuEventPaolo Bonzini
QemuEvents are used heavily by call_rcu. We do not want them to be slow, but the current implementation does a kernel call on every invocation of qemu_event_* and won't cut it. So, wrap a Win32 manual-reset event with a fast userspace path. The states and transitions are the same as for the futex and mutex/condvar implementations, but the slow path is different of course. The idea is to reset the Win32 event lazily, as part of a test-reset-test-wait sequence. Such a sequence is, indeed, how QemuEvents are used by RCU and other subsystems! The patch includes a formal model of the algorithm. Tested-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Weil <sw@weilnetz.de>
