2025-09-01ui/keymaps: Avoid trace crash and improve error messagesMarkus Armbruster1-4/+10
parse_keyboard_layout() passes a possibly null @filename to trace_keymap_parse(). Trace backend log then formats it with %s, which crashes on some systems. Fix by moving the null check before the trace_keymap_parse(). While there, improve the error messages a bit.

2025-08-30hw/arm/stm32f205_soc: Don't leak TYPE_OR_IRQ objectsPeter Maydell2-6/+6
In stm32f250_soc_initfn() we mostly use the standard pattern for child objects of calling object_initialize_child(). However for s->adc_irqs we call object_new() and then later qdev_realize(), and we never unref the object on deinit. This causes a leak, detected by ASAN on the device-introspect-test: Indirect leak of 10 byte(s) in 1 object(s) allocated from: #0 0x5b9fc4789de3 in malloc (/mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/qemu-system-arm+0x21f1de3) (BuildId: 267a2619a026ed91c78a07b1eb2ef15381538efe) #1 0x740de3f28b09 in g_malloc (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x62b09) (BuildId: 1eb6131419edb83b2178b682829a6913cf682d75) #2 0x740de3f3e4d8 in g_strdup (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x784d8) (BuildId: 1eb6131419edb83b2178b682829a6913cf682d75) #3 0x5b9fc70159e1 in g_strdup_inline /usr/include/glib-2.0/glib/gstrfuncs.h:321:10 #4 0x5b9fc70159e1 in object_property_try_add /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:1276:18 #5 0x5b9fc7015f94 in object_property_add /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:1294:12 #6 0x5b9fc701b900 in object_add_link_prop /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:2021:10 #7 0x5b9fc701b3fc in object_property_add_link /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:2037:12 #8 0x5b9fc4c299fb in qdev_init_gpio_out_named /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/core/gpio.c:90:9 #9 0x5b9fc4c29b26 in qdev_init_gpio_out /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/core/gpio.c:101:5 #10 0x5b9fc4c0f77a in or_irq_init /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/core/or-irq.c:70:5 #11 0x5b9fc70257e1 in object_init_with_type /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:428:9 #12 0x5b9fc700cd4b in object_initialize_with_type /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:570:5 #13 0x5b9fc700e66d in object_new_with_type /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:774:5 #14 0x5b9fc700e750 in object_new /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../qom/object.c:789:12 #15 0x5b9fc68b2162 in stm32f205_soc_initfn /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/arm/stm32f205_soc.c:69:26 Switch to using object_initialize_child() like all our other child objects for this SoC object.

2025-08-30scripts/kerneldoc: Switch to the Python kernel-doc scriptPeter Maydell2-6/+3
Change the Sphinx config to run the new Python kernel-doc script instead of the Perl one. The only difference between the two is that the new script does not handle the -sphinx-version option, instead assuming that Sphinx is always at least version 3: so we must delete the code that passes that option to avoid the Python script complaining about an unknown option. QEMU's minimum Sphinx version is already 3.4.3, so this doesn't change the set of versions we can handle.

2025-08-30scripts/kernel-doc: tweak for QEMU coding standardsPeter Maydell1-6/+6
This commit makes the equivalent changes to the Python script that we had for the old Perl script in commit 4cf41794411f ("docs: tweak kernel-doc for QEMU coding standards"). To repeat the rationale from that commit: Surprisingly, QEMU does have a pretty consistent doc comment style and it is not very different from the Linux kernel's. Of the documentation "sigils", only "#" separates the QEMU doc comment style from Linux's, and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in accel/tcg/translate-all.c), so it's clear that the two standards are different in this respect. In addition, our structs are typedefed and recognized by CamelCase names. Note that in 4cf41794411f we used '(?!)' as our type_fallback regex; this is strictly not quite a replacement for the upstream '\&([_\w]+)', because the latter includes a group that can later be matched with \1, and the former does not. The old perl script did not care about this, but the python version does, so we must include the extra set of brackets to ensure we have a group. This commit does not include all the same changes that 4cf41794411f did.

The first change has been refactored into the doc_begin_data and doc_begin_func changes. Since the output HTML for QEMU's documentation has no relevant changes with the new kerneldoc, we assume that this too has been handled upstream.

2025-08-30scripts: Import Python kerneldoc from Linux kernelPeter Maydell6-0/+3346
We last synced our copy of kerneldoc with Linux back in 2020. In the interim, upstream has entirely rewritten the script in Python, and the new Python version is split into a main script plus some libraries in the kernel's scripts/lib/kdoc. Import all these files. These are the versions as of kernel commit 0cc53520e68be, with no local changes. We use the same lib/kdoc/ directory as the kernel does here, so we can avoid having to edit the top-level script just to adjust a pathname, even though it is probably not the naming we would have picked if this was a purely QEMU script. The Sphinx conf.py still points at the Perl version of the script, so this Python code will not be invoked to build the docs yet. NB: checkpatch complains about many things in this commit, including the use of "GPL-2.0" rather than "GPL-2.0-only" in the SPDX tags, but since this is a third party import we can ignore this.

The doc comment for qtest_cb_for_every_machine has a stray space at the start of its description, which makes kernel-doc think that this line is part of the documentation of the skip_old_versioned argument.

2025-08-30scripts/kernel-doc: Avoid new Perl precedence warningPeter Maydell1-5/+4
Newer versions of Perl (5.41.x and up) emit a warning for code in kernel-doc: Possible precedence problem between ! and pattern match (m//) at /scripts/kernel-doc line 1597. This is because the code does: if (!$param =~ /\w\.\.\.$/) { In Perl, the ! operator has higher precedence than the =~ pattern-match binding, so the effect of this condition is to first logically-negate the string $param into a true-or-false value and then try to pattern match it against the regex, which in this case will always fail. This is almost certainly not what the author intended. In the new Python version of kernel-doc in the Linux kernel, the equivalent code is written: if KernRe(r'\w\.\.\.$').search(param): # For named variable parameters of the form `x...`, # remove the dots param = param[:-3] else: # Handles unnamed variable parameters param = "..." which is a more sensible way of writing the behaviour you would get if you put in brackets to make the regex match first and then negate the result. Take this as the intended behaviour, and update the Perl to match. For QEMU, this produces no change in output, presumably because we never used the "unnamed variable parameters" syntax.

2025-08-30hw/intc/arm_gicv3_kvm: preserve pending interrupts during cprSteve Sistare2-0/+18
Close a race condition that causes cpr-transfer to lose VFIO interrupts on ARM. CPR stops VCPUs but does not disable VFIO interrupts, which may continue to arrive throughout the transition to new QEMU. CPR calls kvm_irqchip_remove_irqfd_notifier_gsi in old QEMU to force future interrupts to the producer eventfd, where they are preserved. Old QEMU then destroys the old KVM instance. However, interrupts may already be pending in KVM state. To preserve them, call ioctl KVM_DEV_ARM_VGIC_SAVE_PENDING_TABLES to flush them to guest RAM, where they will be picked up when the new KVM+VCPU instance is created.
