2024-02-05migration/multifd: Drop MultiFDSendParams.normal[] arrayPeter Xu
This array is redundant when p->pages exists. Now we extended the life of p->pages to the whole period where pending_job is set, it should be safe to always use p->pages->offset[] rather than p->normal[]. Drop the array. Alongside, the normal_num is also redundant, which is the same to p->pages->num. This doesn't apply to recv side, because there's no extra buffering on recv side, so p->normal[] array is still needed.

2024-02-05migration/multifd: Postpone reset of MultiFDPages_tPeter Xu
Now we reset MultiFDPages_t object in the multifd sender thread in the middle of the sending job. That's not necessary, because the "*pages" struct will not be reused anyway until pending_job is cleared. Move that to the end after the job is completed, provide a helper to reset a "*pages" object. Use that same helper when free the object too. This prepares us to keep using p->pages in the follow up patches, where we may drop p->normal[].

2024-02-05migration/multifd: Drop MultiFDSendParams.quit, cleanup error pathsPeter Xu
Multifd send side has two fields to indicate error quits: - MultiFDSendParams.quit - &multifd_send_state->exiting Merge them into the global one. The replacement is done by changing all p->quit checks into the global var check. The global check doesn't need any lock. A few more things done on top of this altogether: - multifd_send_terminate_threads() Moving the xchg() of &multifd_send_state->exiting upper, so as to cover the tracepoint, migrate_set_error() and migrate_set_state(). - multifd_send_sync_main() In the 2nd loop, add one more check over the global var to make sure we don't keep the looping if QEMU already decided to quit. - multifd_tls_outgoing_handshake() Use multifd_send_terminate_threads() to set the error state. That has a benefit of updating MigrationState.error to that error too, so we can persist that 1st error we hit in that specific channel. - multifd_new_send_channel_async() Take similar approach like above, drop the migrate_set_error() because multifd_send_terminate_threads() already covers that. Unwrap the helper multifd_new_send_channel_cleanup() along the way; not really needed.

2024-02-05migration: prevent migration when VM has poisoned memoryWilliam Roche
A memory page poisoned from the hypervisor level is no longer readable. The migration of a VM will crash Qemu when it tries to read the memory address space and stumbles on the poisoned page with a similar stack trace: Program terminated with signal SIGBUS, Bus error. #0 _mm256_loadu_si256 #1 buffer_zero_avx2 #2 select_accel_fn #3 buffer_is_zero #4 save_zero_page #5 ram_save_target_page_legacy #6 ram_save_host_page #7 ram_find_and_save_block #8 ram_save_iterate #9 qemu_savevm_state_iterate #10 migration_iteration_run #11 migration_thread #12 qemu_thread_start To avoid this VM crash during the migration, prevent the migration when a known hardware poison exists on the VM.

2024-02-03qapi: Elide "Potential additional modes" from generated docsMarkus Armbruster
Documentation of BlockExportRemoveMode has Potential additional modes to be added in the future: hide: Just hide export from new clients, leave existing connections as is. Remove export after all clients are disconnected. soft: Hide export from new clients, answer with ESHUTDOWN for all further requests from existing clients. I think this is useful only for developers. Elide it from generated documentation by turning it into a TODO section. This effectively reverts my own commit b71fd73cc45 (Revert "qapi: BlockExportRemoveMode: move comments to TODO"). At the time, I was about to elide TODO sections from the generated manual, I wasn't sure about this one, and decided to avoid change. And now I've made up my mind.

2024-02-03target/sparc: Merge check_ieee_exceptions with FPop helpersRichard Henderson
If an exception is to be raised, the destination fp register should be unmodified. The current implementation is incorrect, in that double results will be written back before calling gen_helper_check_ieee_exceptions, despite the placement of gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[]. We can simplify the entire implementation by having each FPOp helper call check_ieee_exceptions.

2024-02-03tcg/loongarch64: Set vector registers call clobberedRichard Henderson
Because there are more call clobbered registers than call saved registers, we begin with all registers as call clobbered and then reset those that are saved. This was missed when we introduced the LSX support.

2024-02-03tests/tcg: Fix the /proc/self/mem probing in the PROT_NONE gdbstub testIlya Leoshkevich
The `if not probe_proc_self_mem` check never passes, because probe_proc_self_mem is a function object, which is a truthy value. Add parentheses in order to perform a function call.
