2025-05-09qtest: introduce qtest_init_extVladimir Sementsov-Ogievskiy3-40/+15
Merge qtest_init_with_env_and_capabilities() and qtest_init_with_env() into one qtest_init_ext(). Reasons: 1. qtest_init_with_env() is just wrong: it gets do_connect parameter but always pass true to qtest_init_with_env_and_capabilities(). Happily, all qtest_init_with_env() callers pass true as well. 2. qtest_init_with_env() is not used outside of libqtest.c, so no reason to keep it as public function 3. and in libqtest.c it's used not often, so no problem to use more generic function instead.

2025-05-08tests/functional: Use -no-shutdown in the hppa_seabios testThomas Huth1-1/+1
qemu-system-hppa shuts down automatically when the BIOS is unable to boot from any device. So this test currently fails occasionally when QEMU already quit, but the test still expected it to be around (e.g. to shut it down cleanly). Adding a "-no-shutdown" seems to make it reliable. While we're at it, also remove the stray "self.machine" in there that does not have any purpose. Signed-off-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Daniel P.

2025-05-06hw/gpio/imx_gpio: Fix interpretation of GDIR polarityBernhard Beschow1-1/+1
According to the i.MX 8M Plus reference manual, a GPIO pin is configured as an output when the corresponding bit in the GDIR register is set. The function imx_gpio_set_int_line() is intended to be a no-op if the pin is configured as an output, returning early in such cases. However, it inverts the condition. Fix this by returning early when the bit is set. cc: qemu-stable@nongnu.org Fixes: f44272809779 ("i.MX: Add GPIO device") Signed-off-by: Bernhard Beschow <shentey@gmail.com> Message-id: 20250501183445.2389-4-shentey@gmail.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2025-05-06target/arm/kvm: Drop support for kernels without KVM_ARM_PREFERRED_TARGETPeter Maydell3-53/+9
Our KVM code includes backwards compatibility support for ancient kernels which don't support the KVM_ARM_PREFERRED_TARGET ioctl. This ioctl was introduced in kernel commit 42c4e0c77ac91 in September 2013 and is in v3.12, so it's reasonable to assume it's present. (We already dropped support for kernels without KVM_CAP_DEVICE_CTRL, a feature added to the kernel in April 2013, in our commit 84f298ea3e; so there are only about six months' worth of kernels, from v3.9 to v3.11, that we don't already fail to run on and that this commit is dropping handling for.)

2025-05-06docs: Don't define duplicate label in qemu-block-drivers.rst.incPeter Maydell2-3/+1
Sphinx requires that labels within documents are unique across the whole manual. This is because the "create a hyperlink" directive specifies only the name of the label, not a filename+label. Some Sphinx versions will warn about duplicate labels, but even if there is no warning there is still an ambiguity and no guarantee that the hyperlink will be created to the right target. For QEMU this is awkward, because we have various .rst.inc fragments which we include into multiple .rst files. If you define a label in the .rst.inc file then it will be a duplicate label. We have mostly worked around this by not putting labels into those .rst.inc files, or by adding "insert a label" functionality into the hxtool extension (see commit 1eeb432a953b0 "doc/sphinx/hxtool.py: add optional label argument to SRST directive"). Unfortunately in commit 7f6314427e78 ("docs/devel: add a codebase section") we accidentally added a duplicate label, because not all Sphinx versions warn about the mistake. In this case the link was only from the developer docs codebase summary, so as the simplest fix for the stable branch, we drop the link entirely.

2025-05-06target/arm: Don't assert() for ISB/SB inside IT blockPeter Maydell1-1/+2
If the guest code has an ISB or SB insn inside an IT block, we generate incorrect code which trips a TCG assertion: qemu-system-arm: ../tcg/tcg-op.c:3343: void tcg_gen_goto_tb(unsigned int): Assertion `(tcg_ctx->goto_tb_issue_mask & (1 << idx)) == 0' failed. This is because we call gen_goto_tb(dc, 1, ...) twice: brcond_i32 ZF,$0x0,ne,$L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x73d948001b81 set_label $L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x73d948001b81 Both calls are in arm_tr_tb_stop(), one for the DISAS_NEXT/DISAS_TOO_MANY handling, and one for the dc->condjump condition-failed codepath. The DISAS_NEXT handling doesn't have this problem because arm_post_translate_insn() does the handling of "emit the label for the condition-failed conditional execution" and so arm_tr_tb_stop() doesn't have dc->condjump set. But for DISAS_TOO_MANY we don't do that. Fix the bug by making arm_post_translate_insn() handle the DISAS_TOO_MANY case. This only affects the SB and ISB insns when used in Thumb mode inside an IT block: only these insns specifically set is_jmp to TOO_MANY, and their A32 encodings are unconditional. For the major TOO_MANY case (breaking the TB because it would cross a page boundary) we do that check and set is_jmp to TOO_MANY only after the call to arm_post_translate_insn(); so arm_post_translate_insn() sees is_jmp == DISAS_NEXT, and we emit the correct code for that situation. With this fix we generate the somewhat more sensible set of TCG ops: brcond_i32 ZF,$0x0,ne,$L1 set_label $L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x7c5434001b81 (NB: the TCG optimizer doesn't optimize out the jump-to-next, but we can't really avoid emitting it because we don't know at the point we're emitting the handling for the condexec check whether this insn is going to happen to be a nop for us or not.)

2025-05-06util: exclude mmap-alloc.c from compilation target on EmscriptenKohei Tokunaga5-8/+41
Emscripten does not support partial unmapping of mmapped memory regions[1]. This limitation prevents correct implementation of qemu_ram_mmap and qemu_ram_munmap, which rely on partial unmap behavior. As a workaround, this commit excludes mmap-alloc.c from the Emscripten build. Instead, for Emscripten build, this modifies qemu_anon_ram_alloc to use qemu_memalign in place of qemu_ram_mmap, and disable memory backends that rely on mmap, such as memory-backend-file and memory-backend-shm.

2025-05-06rust: qom: fix TODO about zeroability of classesPaolo Bonzini1-3/+4
The proposed suggestion is not correct. First it is not necessary for *all* classes to be Zeroable, only for Rust-defined ones; classes defined in C never implement ObjectImpl. Second, the parent class field need not be Zeroable. For example, ChardevClass's chr_write and chr_be_event fields cannot be NULL, therefore ChardevClass cannot be Zeroable. However, char_class_init() initializes them, therefore ChardevClass could be subclassed by Rust code.

"let ... else" is useful when visiting syntax trees; it avoids multiple levels of indentation and places the error close to the pattern. While at it, use "ref" to avoid moving the syntax tree objects. Reviewed-by: Zhao Liu <zhao1.liu@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2025-05-06lcitool: use newer Rust for Debian and UbuntuPaolo Bonzini15-17/+29
On Debian, the rustc-web package provides a newer Rust compiler (1.78) for all architectures except mips64el. On Ubuntu, Rust versions up to 1.80 (?) are available as of this writing for both Jammy (22.04) and Noble (24.04). However, the path to rustc and rustdoc must be provided by hand to the configure script using either command line arguments or environment variables.
