2023-10-21hw/rdma/vmw/pvrdma_cmd: Use correct struct in query_port()Peter Maydell1-7/+11
In query_port() we pass the address of a local pvrdma_port_attr struct to the rdma_query_backend_port() function. Unfortunately, rdma_backend_query_port() wants a pointer to a struct ibv_port_attr, and the two are not the same length. Coverity spotted this (CID 1507146): pvrdma_port_attr is 48 bytes long, and ibv_port_attr is 52 bytes, because it has a few extra fields at the end. Fortunately, all we do with the attrs struct after the call is to read a few specific fields out of it which are all at the same offsets in both structs, so we can simply make the local variable the correct type. This also lets us drop the cast (which should have been a bit of a warning flag that we were doing something wrong here). We do however need to add extra casts for the fields of the struct that are enums: clang will complain about the implicit cast to a different enum type otherwise.

staging target/hppa: Add emulation of a C3700 HP-PARISC workstation This series adds a new PA-RISC machine emulation for the HP-PARISC C3700 workstation. The physical HP C3700 machine has a PA2.0 (64-bit) CPU, in contrast to the existing emulation of a B160L workstation which is a 32-bit only machine and where it's Dino PCI controller isn't 64-bit capable. With the HP C3700 machine emulation (together with the emulated Astro Memory controller and the Elroy PCI bridge) it's now possible to enhance the hppa CPU emulation to support the 64-bit instruction set in upcoming patches.

2023-10-20tests/qtest: Don't print messages from query instancesFabiano Rosas1-1/+8
Now that we can query more than one binary, the "starting QEMU..." message can get a little noisy. Mute those messages unless we're running with --verbose. Only affects qtest_init() calls from within libqtest. The tests continue to output as usual.

2023-10-20tests/qtest/migration: Support more than one QEMU binaryFabiano Rosas1-4/+24
We have strict rules around migration compatibility between different QEMU versions but no test to validate the migration state between different binaries. Add infrastructure to allow running the migration tests with two different QEMU binaries as migration source and destination. The code now recognizes two new environment variables QTEST_QEMU_BINARY_SRC and QTEST_QEMU_BINARY_DST. In the absence of either of them, the test will use the QTEST_QEMU_BINARY variable. If both are missing then the tests are run with single binary as previously. The machine type is selected automatically as the latest machine type version that works with both binaries. Usage (only one of SRC|DST is allowed): QTEST_QEMU_BINARY_SRC=../build-8.2.0/qemu-system-x86_64 \ QTEST_QEMU_BINARY=../build-8.1.0/qemu-system-x86_64 \ ./tests/qtest/migration-test Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Fabiano Rosas <farosas@suse.de> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com> Message-ID: <20231018192741.25885-11-farosas@suse.de>

2023-10-20tests/qtest/migration: Specify the geometry of the bootsectorFabiano Rosas1-1/+3
We're about to enable the x86_64 tests to run with the q35 machine, but that machine does not work with the program we use to dirty the memory for the tests. The issue is that QEMU needs to guess the geometry of the "disk" we give to it and the guessed geometry doesn't pass the sanity checks done by SeaBIOS. This causes SeaBIOS to interpret the geometry as if needing a translation from LBA to CHS and SeaBIOS ends up miscomputing the number of cylinders and aborting due to that. The reason things work with the "pc" machine is that is uses ATA instead of AHCI like q35 and SeaBIOS has an exception for ATA that ends up skipping the sanity checks and ignoring translation altogether. Workaround this situation by specifying a geometry in the command line.

2023-10-20tests/qtest: Introduce qtest_resolve_machine_aliasFabiano Rosas2-0/+26
The migration tests are being enhanced to test migration between different QEMU versions. A requirement of migration is that the machine type between source and destination matches, including the version. We cannot hardcode machine types in the tests because those change with each release. QEMU provides a machine type alias that has a fixed name, but points to the latest machine type at each release. Add a helper to resolve the alias into the exact machine type. E.g. "-machine pc" resolves to "pc-i440fx-8.2" Reviewed-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Fabiano Rosas <farosas@suse.de> Signed-off-by: Juan Quintela <quintela@redhat.com> Message-ID: <20231018192741.25885-6-farosas@suse.de>

2023-10-20migration/multifd: Stop checking p->quit in multifd_send_threadFabiano Rosas1-3/+0
We don't need to check p->quit in the multifd_send_thread() because it is shadowed by the 'exiting' flag. Ever since that flag was added p->quit became obsolete as a way to stop the thread. Since p->quit is set at multifd_send_terminate_threads() under the p->mutex lock, the thread will only see it once it loops, so 'exiting' will always be seen first. Note that setting p->quit at multifd_send_terminate_threads() still makes sense because we need a way to inform multifd_send_pages() that the channel has stopped.

2023-10-20migration: simplify blockersSteve Sistare33-150/+92
Modify migrate_add_blocker and migrate_del_blocker to take an Error ** reason. This allows migration to own the Error object, so that if an error occurs in migrate_add_blocker, migration code can free the Error and clear the client handle, simplifying client code. It also simplifies the migrate_del_blocker call site. In addition, this is a pre-requisite for a proposed future patch that would add a mode argument to migration requests to support live update, and maintain a list of blockers for each mode. A blocker may apply to a single mode or to multiple modes, and passing Error** will allow one Error object to be registered for multiple modes. No functional change.

2023-10-20qapi/s390x/cpu topology: set-cpu-topology qmp commandPierre Morel2-0/+174
The modification of the CPU attributes are done through a monitor command. It allows to move the core inside the topology tree to optimize the cache usage in the case the host's hypervisor previously moved the CPU. The same command allows to modify the CPU attributes modifiers like polarization entitlement and the dedicated attribute to notify the guest if the host admin modified scheduling or dedication of a vCPU. With this knowledge the guest has the possibility to optimize the usage of the vCPUs. The command has a feature unstable for the moment.

When the host supports the CPU topology facility, the PTF instruction with function code 2 is interpreted by the SIE, provided that the userland hypervisor activates the interpretation by using the KVM_CAP_S390_CPU_TOPOLOGY KVM extension. The PTF instructions with function code 0 and 1 are intercepted and must be emulated by the userland hypervisor. During RESET all CPU of the configuration are placed in horizontal polarity.
