2013-09-20s390/sclp: add reset() functionsHeinz Graalfs3-4/+30
Add reset() functions for event-facility, sclpconsole, and sclpquiesce. The reset() functions perform variable initialization at IPL and e.g. when monitor system_reset is called.

To use VMState for migration, we need to adapt some sclp code: - allocate console buffer as part of the console - change semantic of sclpconsole offset fields Signed-off-by: Heinz Graalfs <graalfs@linux.vnet.ibm.com> Reviewed-by: Alexander Graf <agraf@suse.de> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>
2013-09-20kvmvapic: Clear also physical ROM address when entering INACTIVE stateJan Kiszka1-0/+2
To avoid misinterpreting INACTIVE after migration as old qemu-kvm's STANDBY, also clear rom_state_paddr when going back to this state. CC: qemu-stable@nongnu.org Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-09-20kvmvapic: Enter inactive state on hardware resetJan Kiszka1-3/+1
ROM layout may change after reset of devices are hotplugged, so we have to pick up the physical address again when the ROM is initialized. This is best achieved by resetting the state to INACTIVE.

2013-09-19xhci: Init a transfers xhci, slotid and epid member on epctx allocHans de Goede1-3/+3
Transfers are part of an epctx, which is part of a slot, which is part of a xhci. Transfers cannot dynamically be moved from one epctx to another, so once created their xhci, slotid and epid are constant, so lets set these up at creation time, rather then re-initializing them with the same value each time a transfer gets submitted.

The usb-host code has been rewritten for qemu 1.5 to use libusb, the old code has been left in as temporary fallback. Now we are two releases further out, targeting the 1.7 release. No major issues with the new code poped up until now. Time to remove it from tre tree. Should we ever need it again for some reason -- git has a copy for us in the history.

2013-09-16lsi: add 53C810 variantHervé Poussineau1-0/+21
Currently, treat it exactly as a 53C895A. 53C895A is a 53C810 with more capabilities, so this should work. However, this lets us test different code paths on Linux, which don't use lastest features if it detect a 810, or on some OSes which only support 810 and not 895A (like very old Windows NT versions).

2013-09-16lsi: ignore write accesses to CTEST0 registersHervé Poussineau1-0/+3
53C895A datasheet says that this register is read/write, and that the value returned on read access is dependant of DMA FIFO state. However, nothing is said for written value. 53C810A datasheet gives more insight about this register: "This was a general purpose read/write register in previous SYM53C8XX family chips. Although it is still a read/write register, Symbios reserves the right to use these bits for future 53C8XX family enhancements." This prevents going to the default case, which prints an error message. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-09-15pci: remove explicit check to 64K ioport sizeHervé Poussineau1-2/+4
This check is useless, as bigger addresses will be ignored when added to 'io' MemoryRegion, which has a size of 64K. However, some architectures don't use the 'io' MemoryRegion, like the alpha and versatile platforms. They create a PCI I/O region bigger than 64K, so let them handle PCI I/O BARs in the higher range.

At the moment the guest kernel issues two types of task management requests to the hypervisor - task about and lun reset. This adds handling for these tasks. As spapr-vscsi starts calling scsi_req_cancel(), free_request callback was implemented. As virtio-vscsi, spapr-vscsi does not handle CLEAR_ACA either as CDB control byte does not seem to be used at all so NACA bit is not set to the guest so the guest has no good reason to call CLEAR_ACA task.
