2023-05-16tcg: Introduce tcg_target_has_memory_bswapRichard Henderson
Replace the unparameterized TCG_TARGET_HAS_MEMORY_BSWAP macro with a function with a memop argument. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-05-16tcg/riscv: Support softmmu unaligned accessesRichard Henderson
The system is required to emulate unaligned accesses, even if the hardware does not support it. The resulting trap may or may not be more efficient than the qemu slow path. There are linux kernel patches in flight to allow userspace to query hardware support; we can re-evaluate whether to enable this by default after that. In the meantime, softmmu now matches useronly, where we already assumed that unaligned accesses are supported.

2023-05-16tcg/sparc64: Use standard slow path for softmmuRichard Henderson
Drop the target-specific trampolines for the standard slow path. This lets us use tcg_out_helper_{ld,st}_args, and handles the new atomicity bits within MemOp. At the same time, use the full load/store helpers for user-only mode. Drop inline unaligned access support for user-only mode, as it does not handle atomicity. Use TCG_REG_T[1-3] in the tlb lookup, instead of TCG_REG_O[0-2]. This allows the constraints to be simplified.

Always reserve r3 for tlb softmmu lookup. Fix a bug in user-only ALL_QLDST_REGS, in that r14 is clobbered by the BLNE that leads to the misaligned trap.

2023-05-16include/exec/memop: Add MO_ATOM_*Richard Henderson
This field may be used to describe the precise atomicity requirements of the guest, which may then be used to constrain the methods by which it may be emulated by the host. For instance, the AArch64 LDP (32-bit) instruction changes semantics with ARMv8.4 LSE2, from MO_64 | MO_ATOM_IFALIGN_PAIR (64-bits, single-copy atomic only on 4 byte units, nonatomic if not aligned by 4), to MO_64 | MO_ATOM_WITHIN16 (64-bits, single-copy atomic within a 16 byte block) The former may be implemented with two 4 byte loads, or a single 8 byte load if that happens to be efficient on the host. The latter may not be implemented with two 4 byte loads and may also require a helper when misaligned.

In some spots, it would be helpful to be able to use TARGET_NAME in common (target independent) code, too. Thus introduce a wrapper that can be called from common code, too, just like we already have one for target_words_bigendian().

2023-05-16hw/core: Use a callback for target specific query-cpus-fast informationThomas Huth
For being able to create a universal QEMU binary one day, core files like machine-qmp-cmds.c must not contain any "#ifdef TARGET_..." parts. Thus let's provide the target specific function via a function pointer in CPUClass instead, as a first step towards making this file target independent.

2023-05-16docs/devel: remind developers to run CI container pipeline when updating imagesAni Sinha
When new dependencies and packages are added to containers, its important to run CI container generation pipelines on gitlab to make sure that there are no obvious conflicts between packages that are being added and those that are already present. Running CI container pipelines will make sure that there are no such breakages before we commit the change updating the containers. Add a line in the documentation reminding developers to run the pipeline before submitting the change. It will also ease the life of the maintainers.

2023-05-16s390x/pv: Fix spurious warning with asynchronous teardownClaudio Imbrenda
Kernel commit 292a7d6fca33 ("KVM: s390: pv: fix asynchronous teardown for small VMs") causes the KVM_PV_ASYNC_CLEANUP_PREPARE ioctl to fail if the VM is not larger than 2GiB. QEMU would attempt it and fail, print an error message, and then proceed with a normal teardown. Avoid attempting to use asynchronous teardown altogether when the VM is not larger than 2 GiB. This will avoid triggering the error message and also avoid pointless overhead; normal teardown is fast enough for small VMs. Reported-by: Marc Hartmayer <mhartmay@linux.ibm.com> Fixes: c3a073c610 ("s390x/pv: Add support for asynchronous teardown for reboot") Link: https://lore.kernel.org/all/20230421085036.52511-2-imbrenda@linux.ibm.com/ Signed-off-by: Claudio Imbrenda <imbrenda@linux.ibm.com> Message-Id: <20230510105531.30623-2-imbrenda@linux.ibm.com> Reviewed-by: Thomas Huth <thuth@redhat.com> [thuth: Fix inline function parameter in pv.h] Signed-off-by: Thomas Huth <thuth@redhat.com>
