2016-02-06fix MSI injection on XenStefano Stabellini
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.

2016-01-14xen-hvm: Clean up xen_ram_alloc() error handlingMarkus Armbruster
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.

2016-01-14xen-hvm: Clean up xen_hvm_init() error handlingMarkus Armbruster
xen_hvm_init() returns -1 without cleaning up on some errors (harmless long as the caller exit()s on error), dies with hw_error() on others. hw_error() isn't approprate here. Clean up to exit() on all errors.

2014-05-07xen: factor out common functionsWei Liu
So common functions used by both HVM and PV are factored out from xen-all.c to xen-common.c. Finally rename xen-all.c to xen-hvm.c, as those functions are only useful to HVM guest. Create *-stub files and modify Makefile.target to reflect the changes. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
