| * pc: Set CPU model-id on compat_props for pc <= 2.4Eduardo Habkost2016-05-231-0/+29
| | | | | | | | | | | | | | | | | | | | Instead of relying on x86_cpudef_setup() calling qemu_hw_version(), just make old machines set model-id explicitly on compat_props for qemu64, qemu32, and athlon. This will allow us to eliminate x86_cpudef_setup() later. Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

| | | | | | | | | | | | | Include qom/object.h and exec/memory.h instead of exec/ioport.h; exec/ioport.h was almost everywhere required only for those two includes, not for the content of the header itself. Remove block/aio.h, everybody is already including it through another path. With this change, include/hw/hw.h is freed from qemu-common.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* hw: remove pio_addr_tPaolo Bonzini2016-05-191-2/+2
| | | | | | | | | | | | | | | pio_addr_t is almost unused, because these days I/O ports are simply accessed through the address space. cpu_{in,out}[bwl] themselves are almost unused; monitor.c and xen-hvm.c could use address_space_read/write directly, since they have an integer size at hand. This leaves qtest as the only user of those functions. On the other hand even portio_* functions use this type; the only interesting use of pio_addr_t thus is include/hw/sysbus.h. I guess I could move it there, but I don't see much benefit in that either. Using uint32_t is enough and avoids the need to include ioport.h everywhere.

* virtio-blk: use aio handler for data planeMichael S. Tsirkin2016-04-071-0/+2
| | | | | | | | | | | | | | In addition to handling IO in vcpu thread and in io thread, dataplane introduces yet another mode: handling it by AioContext. This reuses the same handler as previous modes, which triggers races as these were not designed to be reentrant. Use a separate handler just for aio, and disable regular handlers when dataplane is active. Signed-off-by: Michael S.

Currently, this reuses the same handler as previous modes, which triggers races as these were not designed to be reentrant.
