2024-03-12physmem: Fix migration dirty bitmap coherency with TCG memory accessNicholas Piggin
The fastpath in cpu_physical_memory_sync_dirty_bitmap() to test large aligned ranges forgot to bring the TCG TLB up to date after clearing some of the dirty memory bitmap bits. This can result in stores though the TCG TLB not setting the dirty memory bitmap and ultimately causes memory corruption / lost updates during migration from a TCG host. Fix this by calling cpu_physical_memory_dirty_bits_cleared() when dirty bits have been cleared.

2024-03-12migration: Fix error handling after dup in file migrationFabiano Rosas
The file migration code was allowing a possible -1 from a failed call to dup() to propagate into the new QIOFileChannel::fd before checking for validity. Coverity doesn't like that, possibly due to the the lseek(-1, ...) call that would ensue before returning from the channel creation routine. Use the newly introduced qio_channel_file_dupfd() to properly check the return of dup() before proceeding.

The Guest VCPU can stop running for numerous reasons including HCALLs, hypervisor exceptions, or an outstanding Host Partition Interrupt. The reason that the Guest VCPU stopped running is communicated through R4 and the output buffer will be filled in with any relevant state.

2024-03-13target/ppc: Remove interrupt handler wrapper functionsBALATON Zoltan
These wrappers call out to handle POWER7 and newer in separate functions but reduce to the generic case when TARGET_PPC64 is not defined. It is easy enough to include the switch in the beginning of the generic functions to branch out to the specific functions and get rid of these wrappers. This avoids one indirection and entirely compiles out the switch without TARGET_PPC64.
