VFIO updates: - Conversion to tracepoints (Eric Auger) - Fix memory listener address space (Frank Blaschka) - Move to hw/vfio/ and split common vs pci (Eric Auger & Kim Phillips) - Trivial error_report() fixes (Alex Williamson) In addition to enabling S390 with the address space fix and updating to use tracepoints rather than compile time debug, this set of patches moves hw/misc/vfio.c to hw/vfio/ and paves the way for vfio-platform support by splitting common functionality from PCI specific code. # gpg: Signature made Mon 22 Dec 2014 20:19:43 GMT using RSA key ID 3BB08B22 # gpg: Good signature from "Alex Williamson <alex.williamson@redhat.com>" # gpg: aka "Alex Williamson <alex@shazbot.org>" # gpg: aka "Alex Williamson <alwillia@redhat.com>" # gpg: aka "Alex Williamson <alex.l.williamson@gmail.com>" * remotes/awilliam/tags/vfio-update-20141222.0: vfio: Cleanup error_report()s hw/vfio: create common module hw/vfio/pci: use name field in format strings hw/vfio/pci: rename group_list into vfio_group_list hw/vfio/pci: split vfio_get_device hw/vfio/pci: Introduce VFIORegion hw/vfio/pci: handle reset at VFIODevice hw/vfio/pci: add type, name and group fields in VFIODevice hw/vfio/pci: introduce minimalist VFIODevice with fd hw/vfio/pci: generalize mask/unmask to any IRQ index hw/vfio/pci: Rename VFIODevice into VFIOPCIDevice vfio: move hw/misc/vfio.c to hw/vfio/pci.c Move vfio.h into include/hw/vfio vfio: fix adding memory listener to the right address space vfio: migration to trace points Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

vfio_get_device now takes a VFIODevice as argument.

This structure is going to be shared by VFIOPCIDevice and VFIOPlatformDevice. VFIOBAR includes it. vfio_eoi becomes an ops of VFIODevice specialized by parent device. This makes possible to transform vfio_bar_write/read into generic vfio_region_write/read that will be used by VFIOPlatformDevice too. vfio_mmap_bar becomes vfio_map_region Signed-off-by: NEric Auger <eric.auger@linaro.org> Signed-off-by: NAlex Williamson <alex.williamson@redhat.com>

Since we can potentially have both PCI and platform devices in the same VFIO group, this latter now owns a list of VFIODevices. A unified reset handler, vfio_reset_handler, is registered, looping through this VFIODevice list. 2 specialized operations are introduced (vfio_compute_needs_reset and vfio_hot_reset_multi): they allow to implement type specific behavior. also reset_works and needs_reset VFIOPCIDevice fields are moved into VFIODevice.

Add 3 new fields in the VFIODevice struct. Type is set to VFIO_DEVICE_TYPE_PCI. The type enum value will later be used to discriminate between VFIO PCI and platform devices. The name is set to domain:bus:slot:function. Currently used to test whether the device already is attached to the group. Later on, the name will be used to simplify all traces. The group is simply moved from VFIOPCIDevice to VFIODevice.

In QEMU 2.2 the exception_index value was added to the migration stream through a subsection. The default was set to 0, which is wrong and should have been -1. However, 2.2 does not have commit e511b4d7 (cpu-exec: reset exception_index correctly, 2014-11-26), hence in 2.2 the exception_index is never used and is set to -1 on the next call to cpu_exec. So we can change the migration stream to make the default -1. The effects are: - 2.2.1 -> 2.2.0: cpu->exception_index set incorrectly to 0 if it were -1 on the source; then reset to -1 in cpu_exec. This is TCG only; KVM does not use exception_index. - 2.2.0 -> 2.2.1: cpu->exception_index set incorrectly to -1 if it were 0 on the source; but it would be reset to -1 in cpu_exec anyway. This is TCG only; KVM does not use exception_index. - 2.2.1 -> 2.1: two bugs fixed: 1) can migrate backwards if cpu->exception_index is set to -1; 2) should not migrate backwards (but 2.2.0 allows it) if cpu->exception_index is set to 0 - 2.2.0 -> 2.3.0: 2.2.0 will send the subsection unnecessarily if exception_index is -1, but that is not a problem. 2.3.0 will set cpu->exception_index to -1 if it is 0 on the source, but this would be anyway a problem for 2.2.0 -> 2.2.x migration (due to lack of commit e511b4d7 in 2.2.x) so we can ignore it - 2.2.1 -> 2.3.0: everything works. In addition, play it safe and never send the subsection unless TCG is in use. KVM does not use exception_index (PPC KVM stores values in it for use in the subsequent call to ppc_cpu_do_interrupt, but does not need it as soon as kvm_handle_debug returns). Xen and qtest do not run any code for the CPU at all.
