2024-01-29migration: Take reference to migration state around bg_migration_vm_start_bhFabiano Rosas1-0/+2
We need to hold a reference to the current_migration object around async calls to avoid it been freed while still in use. Signed-off-by: Fabiano Rosas <farosas@suse.de> Link: https://lore.kernel.org/r/20240119233922.32588-3-farosas@suse.de Signed-off-by: Peter Xu <peterx@redhat.com>
2024-01-29migration: Fix use-after-free of migration state objectFabiano Rosas1-0/+2
We're currently allowing the process_incoming_migration_bh bottom-half to run without holding a reference to the 'current_migration' object, which leads to a segmentation fault if the BH is still live after migration_shutdown() has dropped the last reference to current_migration. In my system the bug manifests as migrate_multifd() returning true when it shouldn't and multifd_load_shutdown() calling multifd_recv_terminate_threads() which crashes due to an uninitialized multifd_recv_state. Fix the issue by holding a reference to the object when scheduling the BH and dropping it before returning from the BH. The same is already done for the cleanup_bh at migrate_fd_cleanup_schedule().

2024-01-29migration/yank: Use channel featuresFabiano Rosas1-5/+1
Stop using outside knowledge about the io channels when registering yank functions. Query for features instead. The yank method for all channels used with migration code currently is to call the qio_channel_shutdown() function, so query for QIO_CHANNEL_FEATURE_SHUTDOWN. We could add a separate feature in the future for indicating whether a channel supports yanking, but that seems overkill at the moment.

2024-01-29ci: Disable migration compatibility tests for aarch64Fabiano Rosas1-0/+4
Until 9.0 is out, we need to keep the aarch64 job disabled because the tests always use the n-1 version of migration-test. That happens to be broken for aarch64 in 8.2. Once 9.0 is out, it will become the n-1 version and it will bring the fixed tests. We can revert this patch when 9.0 releases.

2024-01-29ci: Add a migration compatibility test jobFabiano Rosas1-0/+60
The migration tests have support for being passed two QEMU binaries to test migration compatibility. Add a CI job that builds the lastest release of QEMU and another job that uses that version plus an already present build of the current version and run the migration tests with the two, both as source and destination. I.e.: old QEMU (n-1) -> current QEMU (development tree) current QEMU (development tree) -> old QEMU (n-1) The purpose of this CI job is to ensure the code we're about to merge will not cause a migration compatibility problem when migrating the next release (which will contain that code) to/from the previous release. The version of migration-test used will be the one matching the older QEMU. That way we can avoid special-casing new tests that wouldn't be compatible with the older QEMU. Note: for user forks, the version tags need to be pushed to gitlab otherwise it won't be able to checkout a different version.

2024-01-29migration: Drop unnecessary check in ram's pending_exact()Peter Xu1-5/+4
When the migration frameworks fetches the exact pending sizes, it means this check: remaining_size < s->threshold_size Must have been done already, actually at migration_iteration_run(): if (must_precopy <= s->threshold_size) { qemu_savevm_state_pending_exact(&must_precopy, &can_postcopy); That should be after one round of ram_state_pending_estimate(). It makes the 2nd check meaningless and can be dropped. To say it in another way, when reaching ->state_pending_exact(), we unconditionally sync dirty bits for precopy. Then we can drop migrate_get_current() there too.

2024-01-29cpu-exec: simplify jump cache managementPaolo Bonzini2-46/+28
Unless I'm missing something egregious, the jmp cache is only every populated with a valid entry by the same thread that reads the cache. Therefore, the contents of any valid entry are always consistent and there is no need for any acquire/release magic. Indeed ->tb has to be accessed with atomics, because concurrent invalidations would otherwise cause data races. But ->pc is only ever accessed by one thread, and accesses to ->tb and ->pc within tb_lookup can never race with another tb_lookup. While the TranslationBlock (especially the flags) could be modified by a concurrent invalidation, store-release and load-acquire operations on the cache entry would not add any additional ordering beyond what you get from performing the accesses within a single thread. Because of this, there is really nothing to win in splitting the CF_PCREL and !CF_PCREL paths. It is easier to just always use the ->pc field in the jump cache. I noticed this while working on splitting commit 8ed558ec0cb ("accel/tcg: Introduce TARGET_TB_PCREL", 2022-10-04) into multiple pieces, for the sake of finding a more fine-grained bisection result for https://gitlab.com/qemu-project/qemu/-/issues/2092. It does not (and does not intend to) fix that issue; therefore it may make sense to not commit it until the root cause of issue #2092 is found.

The const_le64() macro introduced in commit 845d80a8c7b187 turns out to have a bug which means that on big-endian systems the compiler complains if the argument isn't already a 64-bit type. This hasn't caused a problem yet, because there are no in-tree uses, but it means it's not possible for anybody to add one without it failing CI. This example is from an attempted use of it with the argument '0', from the s390 CI runner's gcc: ../block/blklogwrites.c: In function ‘blk_log_writes_co_do_log’: ../include/qemu/bswap.h:148:36: error: left shift count >= width of type [-Werror=shift-count-overflow] 148 | ((((_x) & 0x00000000000000ffU) << 56) | \ | ^~ ../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’ 409 | .nr_entries = const_le64(0), | ^~~~~~~~~~ ../include/qemu/bswap.h:149:36: error: left shift count >= width of type [-Werror=shift-count-overflow] 149 | (((_x) & 0x000000000000ff00U) << 40) | \ | ^~ ../block/blklogwrites.c:409:27: note: in expansion of macro ‘const_le64’ 409 | .nr_entries = const_le64(0), | ^~~~~~~~~~ cc1: all warnings being treated as errors Fix this by making all the constants in the macro have the ULL suffix.

2024-01-26target/arm: Fix A64 scalar SQSHRN and SQRSHRNPeter Maydell1-1/+1
In commit 1b7bc9b5c8bf374dd we changed handle_vec_simd_sqshrn() so that instead of starting with a 0 value and depositing in each new element from the narrowing operation, it instead started with the raw result of the narrowing operation of the first element. This is fine in the vector case, because the deposit operations for the second and subsequent elements will always overwrite any higher bits that might have been in the first element's result value in tcg_rd. However in the scalar case we only go through this loop once. The effect is that for a signed narrowing operation, if the result is negative then we will now return a value where the bits above the first element are incorrectly 1 (because the narrowfn returns a sign-extended result, not one that is truncated to the element size). Fix this by using an extract operation to get exactly the correct bits of the output of the narrowfn for element 1, instead of a plain move.

2024-01-26hw/char/imx_serial: Implement receive FIFO and ageing timerRayhan Faizel2-14/+108
This patch implements a 32 half word FIFO as per imx serial device specifications. If a non empty FIFO is below the trigger level, an ageing timer will tick for a duration of 8 characters. On expiry, AGTIM will be set triggering an interrupt. AGTIM timer resets when there is activity in the receive FIFO. Otherwise, RRDY is set when trigger level is exceeded. The receive trigger level is 8 in newer kernel versions and 1 in older ones. This change will break migration compatibility for the imx boards.

2024-01-26docs/system/arm/virt.rst: Add note on CPU features off by defaultGustavo Romero1-0/+13
Add a note on CPU features that are off by default in `virt` machines. Some CPU features will remain off even if a CPU-capable CPU (e.g., `-cpu max`) is selected because they require support in both the CPU itself and in the wider system. Therefore, the user, besides selecting a CPU that supports such features, must also turn on the feature using a machine option.

2024-01-26fsl-imx6ul: Add various missing unimplemented devicesGuenter Roeck2-0/+32
Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices. This allows operating systems such as Linux to run emulations such as mcimx6ul-evk. Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected memory ranges were covered by the unimplemented DAP device. The commit reduced the DAP address range from 0x100000 to 4kB, and the emulation thus no longer covered the various unimplemented devices in the affected address range.
