acpi,pci,pc,virtio fixes and enhancements This includes new unit-tests for acpi by Marcel, hotplug for pci bridges by myself (piix only so far) and cpu hotplug for q35. And a bunch of fixes all over the place as usual. I included the patch to fix memory alignment for q35 as well - even though it limits 32 bit guests to 3G (they previously could address more memory with PAE). To remove the limit, this will have to be fixed in seabios. I also added self as virtio co-maintainer so I don't need to troll the list for patches to review. Signed-off-by: Michael S.

Introduces USER_CREATABLE interface that must be implemented by objects which are designed to created with -object CLI option or object-add QMP command. Interface provides an ability to do an optional second stage initialization of the object created with -object/object-add commands. By providing complete() callback, which is called after the object properties were set. It allows to: * prevents misusing of -object/object-add by filtering out objects that are not designed for it. * generalize second stage backend initialization instead of adding custom APIs to perform it * early error detection of backend initialization at -object/ object-add time rather than through a proxy DEVICE object that tries to use backend.

Add ACPI based PCI hotplug library with bridge hotplug support. Design - each bus gets assigned "bsel" property. - ACPI code writes this number to a new BNUM register, then uses existing UP/DOWN registers to probe slot status; to eject, write number to BNUM register, then slot into existing EJ. The interface is actually backwards-compatible with existing PIIX4 ACPI (though not migration compatible). This is split out from PIIX4 codebase so we can reuse it for Q35 as well.

2014-01-24block: Allow wait_serialising_requests() at any pointKevin Wolf1-0/+2
We can only have a single wait_serialising_requests() call per request because otherwise we can run into deadlocks where requests are waiting for each other. The same is true when wait_serialising_requests() is not at the very beginning of a request, so that other requests can be issued between the start of the tracking and wait_serialising_requests(). Fix this by changing wait_serialising_requests() to ignore requests that are already (directly or indirectly) waiting for the calling request.

2014-01-24block: Don't use guest sector size for qemu_blockalign()Kevin Wolf2-0/+6
bs->buffer_alignment is set by the device emulation and contains the logical block size of the guest device. This isn't something that the block layer should know, and even less something to use for determining the right alignment of buffers to be used for the host. The new BlockLimits field opt_mem_alignment tells the qemu block layer the optimal alignment to be used so that no bounce buffer must be used in the driver. This patch may change the buffer alignment from 4k to 512 for all callers that used qemu_blockalign() with the top-level image format BlockDriverState. The value was never propagated to other levels in the tree, so in particular raw-posix never required anything else than 512. While on disks with 4k sectors direct I/O requires a 4k alignment, memory may still be okay when aligned to 512 byte boundaries. This is what must have happened in practice, because otherwise this would already have failed earlier. Therefore I don't expect regressions even with this intermediate state. Later, raw-posix can implement the hook and expose a different memory alignment requirement.

Signed-off-by: Benoit Canet <benoit@irqsave.net> Reviewed-by: Fam Zheng <famz@redhat.com> There was two candidate ways to implement named node manipulation: 1) { 'command': 'block_passwd', 'data': {'*device': 'str', '*node-name': 'str', 'password': 'str'} } 2) { 'command': 'block_passwd', 'data': {'device': 'str', '*device-is-node': 'bool', 'password': 'str'} } Luiz proposed 1 and says 2 was an abuse of the QMP interface and proposed to rewrite the QMP block interface for 2.0. Luiz does not like in 1 the fact that 2 fields are optional but one of them must be specified leading to an abuse of the QMP semantic. Kevin argumented that 2 what a clear abuse of the device field and would not be practical when reading fast some log file because the user would read "device" and think that a device is manipulated when it's in fact a node name. Documentation of 1 make it pretty clear what to do for the user. Kevin argued that all bs are node including devices ones so 2 does not make sense. Kevin also argued that rewriting the QMP block interface would not make disapear the current one. Kevin pushed the argument that making the QAPI generator compatible with the semantic of the operation would need a rewrite that no one has done yet.

This way readline.c does not know about Monitor and other users will be able to make use of readline.c. Note that there is already an "opaque" argument to the ReadLineFunc callback. Consistently call it "readline_opaque" from now on to distinguish from the ReadLinePrintfFunc/ReadLineFlushFunc "opaque" argument. I also dropped the printf macro trickery since it's now highly unlikely that anyone modifying readline.c would call printf(3) directly. We no longer need this protection.

2014-01-13memory: syncronize kvm bitmap using bitmaps operationsJuan Quintela1-18/+36
If bitmaps are aligned properly, use bitmap operations. If they are not, just use old bit at a time code. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Orit Wasserman <owasserm@redhat.com>
2014-01-13memory: move bitmap synchronization to its own functionJuan Quintela1-0/+31
We want to have all the functions that handle directly the dirty bitmap near. We will change it later. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Orit Wasserman <owasserm@redhat.com>
2014-01-13memory: split cpu_physical_memory_* functions to its own includeJuan Quintela2-76/+98
All the functions that use ram_addr_t should be here. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Orit Wasserman <owasserm@redhat.com>
2014-01-13memory: make cpu_physical_memory_reset_dirty() take a length parameterJuan Quintela1-1/+1
We have an end parameter in all the callers, and this make it coherent with the rest of cpu_physical_memory_* functions, that also take a length parameter. Once here, move the start/end calculation to tlb_reset_dirty_range_all() as we don't need it here anymore.
