2021-08-26target/arm/cpu64: Replace kvm_supported with sve_vq_supportedAndrew Jones1-8/+11
Now that we have an ARMCPU member sve_vq_supported we no longer need the local kvm_supported bitmap for KVM's supported vector lengths.

2021-08-26target/arm/kvm64: Ensure sve vls map is completely clearAndrew Jones1-1/+1
bitmap_clear() only clears the given range. While the given range should be sufficient in this case we might as well be 100% sure all bits are zeroed by using bitmap_zero().

2021-08-26target/arm/cpu: Introduce sve_vq_supported bitmapAndrew Jones2-0/+6
Allow CPUs that support SVE to specify which SVE vector lengths they support by setting them in this bitmap. Currently only the 'max' and 'host' CPU types supports SVE and 'host' requires KVM which obtains its supported bitmap from the host. So, we only need to initialize the bitmap for 'max' with TCG. And, since 'max' should support all SVE vector lengths we simply fill the bitmap. Future CPU types may have less trivial maps though.

Since commit 36b79e3219d ("hw/acpi/Kconfig: Add missing Kconfig dependencies (build error)"), ACPI_MEMORY_HOTPLUG and ACPI_NVDIMM is implicitly turned on when ACPI_HW_REDUCED is selected.

2021-08-26vl: Clean up -smp error handlingMarkus Armbruster1-7/+5
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. machine_parse_property_opt() is wrong that way: it passes @errp to keyval_parse() without checking for failure, then passes it to keyval_merge(). Harmless, since the only caller passes &error_fatal. Clean up: drop the parameter, and use &error_fatal directly.

2021-08-26migration: Handle migration_incoming_setup() errors consistentlyMarkus Armbruster1-18/+9
Commit b673eab4e2 "multifd: Make multifd_load_setup() get an Error parameter" changed migration_incoming_setup() to take an Error ** argument, and adjusted the callers accordingly. It neglected to change adjust multifd_load_setup(): it still exit()s on error. Clean that up. The error now gets propagated up two call chains: via migration_fd_process_incoming() to rdma_accept_incoming_migration(), and via migration_ioc_process_incoming() to migration_channel_process_incoming(). Both chain ends report the error with error_report_err(), but otherwise ignore it. Behavioral change: we no longer exit() on this error. This is consistent with how we handle other errors here, e.g. from multifd_recv_new_channel() via migration_ioc_process_incoming() to migration_channel_process_incoming(). Whether it's consistently right or consistently wrong I can't tell. Also clean up the return value from the unusual 0 on success, 1 on error to the more common true on success, false on error.

2021-08-26i386: Never free migration blocker objects instead of sometimesMarkus Armbruster1-3/+0
invtsc_mig_blocker has static storage duration. When a CPU with certain features is initialized, and invtsc_mig_blocker is still null, we add a migration blocker and store it in invtsc_mig_blocker. The object is freed when migrate_add_blocker() fails, leaving invtsc_mig_blocker dangling. It is not freed on later failures. Same for hv_passthrough_mig_blocker and hv_no_nonarch_cs_mig_blocker. All failures are actually fatal, so whether we free or not doesn't really matter, except as bad examples to be copied / imitated. Clean this up in a minimal way: never free these blocker objects.

spapr_mce_req_event() makes an effort to prevent migration from degrading the reporting of FWNMIs. It adds a migration blocker when it receives one, and deletes it when it's done handling it. This is a best effort. Commit 2500fb423a "migration: Include migration support for machine check handling" tried to explain this in a comment.

2021-08-26qapi: Fix crash on redefinition with a different conditionMarkus Armbruster2-12/+12
QAPISchema._make_implicit_object_type() asserts that when an implicit object type is used multiple times, @ifcond is the same for all uses. It will be for legitimate uses, i.e. simple union branch wrapper types. A comment explains this. The assertion fails when a command or event is redefined with a different condition. The redefinition is an error, but it's flagged only later. Fixing the assertion would complicate matters further. Not worthwhile, drop it instead. We really need to get rid of simple unions. Tweak test case redefined-event to cover redefinition with a different condition.
