2012-03-14qom/object.c: rename type_class_init() to type_initialize()Igor Mitsyanko1-6/+6
Function name type_class_init() gave us a wrong impression of separation of type's "class" and "object" entities initialization. Name type_initialize() is more appropriate for type_class_init() function (considering what operations it performs).

2012-03-14qom: if @instance_size==0, assign size of object to parent object sizeIgor Mitsyanko1-2/+17
QOM documentation states that for objects of type with @instance_size == 0 size will be assigned to match parent object's size. But currently this feauture is not implemented and qemu asserts during creation of object with zero instance_size. Set appropriate value for type instance_size during type_class_init() call. object_initialize_with_type() must call type_class_init() before asserting type->instance_size, and object_new_with_type() must call type_class_init() before object allocation.

2012-03-14kvmvapic: align start address as well as sizeAvi Kivity1-1/+3
The kvmvapic code remaps a section of ROM as RAM to allow the guest to maintain state there. It is careful to align the section size to a page boundary, to avoid creating subpages, but neglects to do the same for the start address. These leads to an assert later on when the memory core tries to create a page which is half RAM and half ROM. Fix by aligning the start address to a page boundary. This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-03-13kvmclock: Always register typeAndreas Färber1-2/+0
Currently, the "kvmclock" type is only registered when kvm_enabled(). This breaks when moving type registration to before command line parsing (so that QOM types can be used for CPU and machine). Since the QOM classes are lazy-initialized anyway and kvmclock_create() has another kvm_enabled() check, simply drop the KVM check in kvmclock_register_types(). kvm-i8259, kvm-apic and kvm-ioapic do not suffer from such a check.

2012-03-13slirp: Fix compiler warning for w64Stefan Weil1-1/+1
Casting a pointer to an integer value must use uintptr_t or intptr_t (not long) for portable code. MinGW-w64 requires this because sizeof(long) != sizeof(void *) for w64 hosts, so casting to long raises a compiler warning. I use uintptr_t instead of intptr_t because changing the sign does not matter here and casting pointers to unsigned values seems more reasonable (the unsigned value is a non negative offset.

There is now a trivial check on entry of if_start for pending packets, so we can drop the additional tracking via if_queued. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2012-03-13slirp: Fix queue walking in if_startJan Kiszka1-21/+39
Another attempt to get this right: We need to carefully walk both the fastq and the batchq in if_start while trying to send packets to possibly not yet resolved hosts on the virtual network. So far we just requeued a delayed packet where it was and then started walking the queues from the top again - that couldn't work. Now we pre- calculate the next packet in the queue so that the current one can safely be removed if it was sent successfully. We also need to take into account that the next packet can be from the same session if the current one was sent and there are no other sessions.

2012-03-13usb-ohci: DMA writeback bug fixesWei Yang1-2/+15
This patch fixes two bugs in the OHCI device where the device writes back data to system memory that should be exclusively under the control of the guest side driver. In OHCI specification Section 5.2.7, it mentioned "In all cases, Host Controller Driver is responsible for the insertion and removal of all Endpoint Descriptors in the various Host Controller Endpoint Descriptor lists". In the ohci_frame_boundary(), ohci_put_hcca() writes the entire hcca back including the interrupt ED lists which should be under driver control. This violates the specification and can race with a host driver updating that list at the same time. In the OHCI Spec Section 4.6, Transfer Descriptor Queue Processing, it mentioned "Since the TD pointed to by TailP is not accessed by the HC, the Host Controller Driver can initialize that TD and link at least one other to it without creating a coherency or synchronization problem". While the function ohci_put_ed() writes the entire endpoint descriptor back including the TailP which should under driver control. This violate the specification and can race with a host driver updating the TD list at the same time. In each case the solution is to make sure we don't write data which is under driver control.

2012-03-12qemu-ga: add guest-sync-delimitedMichael Roth5-9/+77
guest-sync leaves it as an exercise to the user as to how to reliably obtain the response to guest-sync if the client had previously read in a partial response (due qemu-ga previously being restarted mid-"sentence" due to reboot, forced restart, etc). qemu-ga handles this situation on its end by having a client precede their guest-sync request with a 0xFF byte (invalid UTF-8), which qemu-ga/QEMU JSON parsers will treat as a flush event. Thus we can reliably flush the qemu-ga parser state in preparation for receiving the guest-sync request. guest-sync-delimited provides the same functionality for a client: when a guest-sync-delimited is issued, qemu-ga will precede it's response with a 0xFF byte that the client can use as an indicator to flush its buffer/parser state in preparation for reliably receiving the guest-sync-delimited response. It is also useful as an optimization for clients, since, after issuing a guest-sync-delimited, clients can safely discard all stale data read from the channel until the 0xFF is found.
