2018-05-23job: Create Job, JobDriver and job_create()Kevin Wolf
This is the first step towards creating an infrastructure for generic background jobs that aren't tied to a block device. For now, Job only stores its ID and JobDriver, the rest stays in BlockJob. The following patches will move over more parts of BlockJob to Job if they are meaningful outside the context of a block job. BlockJob.driver is now redundant, but this patch leaves it around to avoid unnecessary churn. The next patches will get rid of almost all of its uses anyway so that it can be removed later with much less churn.

2018-03-02qapi: Empty out qapi-schema.jsonMarkus Armbruster
The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day. Adding a type to qapi/migration.json now recompiles some 120 instead of 2300 out of 5100 objects.

2018-03-02qapi: Generate separate .h, .c for each moduleMarkus Armbruster
Our qapi-schema.json is composed of modules connected by include directives, but the generated code is monolithic all the same: one qapi-types.h with all the types, one qapi-visit.h with all the visitors, and so forth. These monolithic headers get included all over the place. In my "build everything" tree, adding a QAPI type recompiles about 4800 out of 5100 objects. We wouldn't write such monolithic headers by hand. It stands to reason that we shouldn't generate them, either. Split up generated qapi-types.h to mirror the schema's modular structure: one header per module. Name the main module's header qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h. Mirror the schema's includes in the headers, so that qapi-types.h gets you everything exactly as before. If you need less, you can include one or more of the sub-module headers. To be exploited shortly. Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h, qmp-commands.c, qapi-event.h, qapi-event.c the same way. qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic. The split of qmp-commands.c duplicates static helper function qmp_marshal_output_str() in qapi-commands-char.c and qapi-commands-misc.c. This happens when commands returning the same type occur in multiple modules. Not worth avoiding. Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and qmp-commands.[ch] to qapi-commands.[ch], name the shards that way already, to reduce churn. This requires temporary hacks in commands.py and events.py. Similarly, c_name() must temporarily be taught to munge '/' in common.py. They'll go away with the rename.

2018-03-02qapi/types qapi/visit: Generate built-in stuff into separate filesMarkus Armbruster
Linking code from multiple separate QAPI schemata into the same program is possible, but involves some weirdness around built-in types: * We generate code for built-in types into .c only with option --builtins. The user is responsible for generating code for exactly one QAPI schema per program with --builtins. * We generate code for built-in types into .h regardless of --builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN. Because all copies of this code are exactly the same, including any combination of these headers works. Replace this contraption by something more conventional: generate code for built-in types into their very own files: qapi-builtin-types.c, qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but only with --builtins. Obey --output-dir, but ignore --prefix for them. Make qapi-types.h include qapi-builtin-types.h. With multiple schemata you now have multiple qapi-types.[ch], but only one qapi-builtin-types.[ch]. Same for qapi-visit.[ch] and qapi-builtin-visit.[ch]. Bonus: if all you need is built-in stuff, you can include a much smaller header. To be exploited shortly.

2018-02-19hw/rdma: Implementation of PVRDMA deviceYuval Shaia
PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device. It works with its Linux Kernel driver AS IS, no need for any special guest modifications. While it complies with the VMware device, it can also communicate with bare metal RDMA-enabled machines and does not require an RDMA HCA in the host, it can work with Soft-RoCE (rxe). It does not require the whole guest RAM to be pinned allowing memory over-commit and, even if not implemented yet, migration support will be possible with some HW assistance. Implementation is divided into 2 components, rdma general and pvRDMA specific functions and structures. The second PVRDMA sub-module - interaction with PCI layer. - Device configuration and setup (MSIX, BARs etc). - Setup of DSR (Device Shared Resources) - Setup of device ring. - Device management.

2017-09-22scsi, file-posix: add support for persistent reservation managementPaolo Bonzini
It is a common requirement for virtual machine to send persistent reservations, but this currently requires either running QEMU with CAP_SYS_RAWIO, or using out-of-tree patches that let an unprivileged QEMU bypass Linux's filter on SG_IO commands. As an alternative mechanism, the next patches will introduce a privileged helper to run persistent reservation commands without expanding QEMU's attack surface unnecessarily. The helper is invoked through a "pr-manager" QOM object, to which file-posix.c passes SG_IO requests for PERSISTENT RESERVE OUT and PERSISTENT RESERVE IN commands. For example: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -drive if=none,id=hd,driver=raw,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd or: $ qemu-system-x86_64 -device virtio-scsi \ -object pr-manager-helper,id=helper0,path=/var/run/qemu-pr-helper.sock -blockdev node-name=hd,driver=raw,file.driver=host_device,file.filename=/dev/sdb,file.pr-manager=helper0 -device scsi-block,drive=hd Multiple pr-manager implementations are conceivable and possible, though only one is implemented right now. For example, a pr-manager could: - talk directly to the multipath daemon from a privileged QEMU (i.e. QEMU links to libmpathpersist); this makes reservation work properly with multipath, but still requires CAP_SYS_RAWIO - use the Linux IOC_PR_* ioctls (they require CAP_SYS_ADMIN though) - more interestingly, implement reservations directly in QEMU through file system locks or a shared database (e.g. sqlite) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-09-19scsi: move non-emulation specific code to scsi/Paolo Bonzini
util/scsi.c includes some SCSI code that is shared by block/iscsi.c and hw/scsi, but the introduction of the persistent reservation helper will add many more instances of this. There is also include/block/scsi.h, which actually is not part of the core block layer. The persistent reservation manager will also need a home. A scsi/ directory provides one for both the aforementioned shared code and the PR manager code.

The purpose of the code is to show how a backend can be implemented and to test the vhost-user-scsi Qemu implementation. If a different instance of this vhost-user-scsi application is executed at a remote host, a VM can be live migrated to such a host.

2017-01-31trace: switch to modular code generation for sub-directoriesDaniel P. Berrange
Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-12-16contrib: add libvhost-userMarc-André Lureau
Add a library to help implementing vhost-user backend (or slave). Dealing with vhost-user as an application developer isn't so easy: you have all the trouble with any protocol: validation, unix ancillary data, shared memory, eventfd, logging, and on top of that you need to deal with virtio queues, if possible efficiently. qemu test has a nice vhost-user testing application vhost-user-bridge, which implements most of vhost-user, and virtio.c which implements virtqueues manipulation. Based on these two, I tried to make a simple library, reusable for tests or development of new vhost-user scenarios.
