| | | | | | | | | | | | Re-run scripts/clean-includes to apply the previous commit's corrections and updates. Besides redundant qemu/typedefs.h, this only finds a redundant config-host.h include in ui/egl-helpers.c. No idea how that escaped the previous runs. Some manual whitespace trimming around dropped includes squashed in. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* xen: drop support for Xen 4.1 and older.Ian Campbell2016-02-101-4/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | Xen 4.2 become unsupported upstream in 09/2015 (see http://wiki.xen.org/wiki/Xen_Release_Features). However as far as the interfaces provided by the toolstack libraries go 4.2 and 4.3 are indistinguishable. Therefore drop support for Xen 4.1 and earlier which removes a whole pile of compatibility code which makes future work (to use stable library interfaces provided by upstream) more difficult. In particular all supported versions now use a pointer as a libxc handle (4.1 and earlier used an integer, resulting in various shim layers). Also Xen 4.2 was the first version of Xen to formally support upstream QEMU (as a preview) so that makes sense as a cut-off now. This change drops all the configure-y and resulting ifdefs in a mostly mechanical way. A follow up will refactor wrappers which are now unused.

* fix MSI injection on XenStefano Stabellini2016-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | On Xen MSIs can be remapped into pirqs, which are a type of event channels. It's mostly for the benefit of PCI passthrough devices, to avoid the overhead of interacting with the emulated lapic. However remapping interrupts and MSIs is also supported for emulated devices, such as the e1000 and virtio-net. When an interrupt or an MSI is remapped into a pirq, masking and unmasking is done by masking and unmasking the event channel. The masking bit on the PCI config space or MSI-X table should be ignored, but it isn't at the moment. As a consequence emulated devices which use MSI or MSI-X, such as virtio-net, don't work properly (the guest doesn't receive any notifications). The mechanism was working properly when xen_apic was introduced, but I haven't narrowed down which commit in particular is causing the regression. Fix the issue by ignoring the masking bit for MSI and MSI-X which have been remapped into pirqs. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Reviewed-by: Michael S.

* xen-hvm: Clean up xen_ram_alloc() error handlingMarkus Armbruster2016-01-141-1/+1
| | | | | | | | | | | | | xen_ram_alloc() dies with hw_error() on error, even though its caller ram_block_add() handles errors just fine. Add an Error **errp parameter and use it. Leave case RUN_STATE_INMIGRATE alone, because that looks like some kind of warning.

* accel: Move Xen registration code to xen-common.cEduardo Habkost2014-10-041-1/+0Star
| | | | | | | | | | | | | | | | Note that this has an user-visible side-effect: instead of reporting "Xen is not supported for this target", QEMU binaries not supporting Xen will report "xen accelerator does not exist". As xen_available() always return 1 when CONFIG_XEN is enabled, we don't need to set AccelClass.available anymore. xen_enabled() is not being removed yet, but only because vl.c is still using it. This also allows us to make xen_init() static. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* KVM: Split QEMUMachine typedef into separate headerAlexander Graf2014-03-051-0/+1
| | | | | | | | | | | | | | | | Older gcc versions (such as the one in SLES11) get confused when you declare a typedef on the same struct twice. To work around that limitation, let's extract the QEMUMachine typedef into a separate header file that is guarded by preprocessor duplicate include checks. This fixes the following type of compile errors for me: In file included from vl.c:125: include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine" include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here Signed-off-by: Alexander Graf <agraf@suse.de>

* hw: move headers to include/Paolo Bonzini2013-04-081-0/+62
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
