2024-12-10rust: build: restrict --cfg generation to only required symbolsPaolo Bonzini2-17/+46
Parse the Cargo.toml file, looking for the unexpected_cfgs configuration. When generating --cfg options from the config-host.h file, only use those that are included in the configuration. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-12-10rust: build: move rustc_args.py invocation to qemu-api cratePaolo Bonzini2-32/+29
Only qemu-api needs access to the symbols in config-host.h. Remove the temptation to use them elsewhere by limiting the --cfg arguments to the qemu-api crate. Per-crate invocation of the script will also be needed to add --check-cfg options for each crate's features (when more complex, build-time configurable devices are added in the future).

2024-12-10rust: allow using build-root bindings.rs from cargoPaolo Bonzini8-35/+63
Right now, using cargo with QEMU requires copying by hand the bindings.rs to the source tree. Instead, we can use an include file to escape the cage of cargo's mandated source directory structure. By running cargo within meson's "devenv" and adding a MESON_BUILD_ROOT environment variable, it is easy for build.rs to find the file. However, the file must be symlinked into cargo's output directory for rust-analyzer to find it. Suggested-by: Junjie Mao <junjie.mao@hotmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-12-10rust: apply --cfg MESON to all cratesPaolo Bonzini2-4/+5
We might have more uses for --cfg MESON, even though right now it's only qemu-api that has generated files. Since we're going to add more flags to the add_project_arguments calls for Rust, it makes sense to also add --cfg MESON everywhere. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-12-03hw/virtio: fix crash in processing balloon statsDaniel P. Berrangé1-1/+15
balloon_stats_get_all will iterate over guest stats upto the max VIRTIO_BALLOON_S_NR value, calling visit_type_uint64 to populate the QObject dict. The dict keys are obtained from the static array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size. Unfortunately the way that array is declared results in any unassigned stats getting a NULL name, which will then cause visit_type_uint64 to trigger an assert in qobject_output_add_obj. The balloon_stat_names array was fortunately fully populated with names until recently: commit 0d2eeef77a33315187df8519491a900bde4a3d83 Author: Bibo Mao <maobibo@loongson.cn> Date: Mon Oct 28 10:38:09 2024 +0800 linux-headers: Update to Linux v6.12-rc5 pulled a change to include/standard-headers/linux/virtio_balloon.h which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new names to balloon_stat_names. This commit fills in the missing names, and uses a static assert to guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause a build failure until balloon_stat_names is updated. This problem was detected by the Cockpit Project's automated integration tests on QEMU 9.2.0-rc1.

2024-12-03hw/display/vga: Do not reset 'big_endian_fb' in vga_common_reset()Philippe Mathieu-Daudé1-1/+1
The 'pci-vga' device allow setting a 'big-endian-framebuffer' property since commit 3c2784fc864 ("vga: Expose framebuffer byteorder as a QOM property"). Similarly, the 'virtio-vga' device since commit 8be61ce2ce3 ("virtio-vga: implement big-endian-framebuffer property"). Both call vga_common_reset() in their reset handler, respectively pci_secondary_vga_reset() and virtio_vga_base_reset_hold(), which reset 'big_endian_fb', overwritting the property. This is not correct: the hardware is expected to keep its configured endianness during resets. Move 'big_endian_fb' assignment from vga_common_reset() to vga_common_init() which is called once when the common VGA state is initialized.

2024-12-03target/riscv: Avoid bad shift in riscv_cpu_do_interrupt()Peter Maydell1-4/+4
In riscv_cpu_do_interrupt() we use the 'cause' value we got out of cs->exception as a shift value. However this value can be larger than 31, which means that "1 << cause" is undefined behaviour, because we do the shift on an 'int' type. This causes the undefined behaviour sanitizer to complain on one of the check-tcg tests: $ UBSAN_OPTIONS=print_stacktrace=1:abort_on_error=1:halt_on_error=1 ./build/clang/qemu-system-riscv64 -M virt -semihosting -display none -device loader,file=build/clang/tests/tcg/riscv64-softmmu/issue1060 ../../target/riscv/cpu_helper.c:1805:38: runtime error: shift exponent 63 is too large for 32-bit type 'int' #0 0x55f2dc026703 in riscv_cpu_do_interrupt /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/clang/../../target/riscv/cpu_helper.c:1805:38 #1 0x55f2dc3d170e in cpu_handle_exception /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/clang/../../accel/tcg/cpu-exec.c:752:9 In this case cause is RISCV_EXCP_SEMIHOST, which is 0x3f.

2024-12-03hw/openrisc/openrisc_sim: keep serial@90000000 as defaultAhmad Fatoum1-6/+20
We used to only have a single UART on the platform and it was located at address 0x90000000. When the number of UARTs was increased to 4, the first UART remained at it's location, but instead of being the first one to be registered, it became the last. This caused QEMU to pick 0x90000300 as the default UART, which broke software that hardcoded the address of 0x90000000 and expected it's output to be visible when the user configured only a single console. This caused regressions[1] in the barebox test suite when updating to a newer QEMU. As there seems to be no good reason to register the UARTs in inverse order, let's register them by ascending address, so existing software can remain oblivious to the additional UART ports. Changing the order of uart registration alone breaks Linux which was choosing the UART at 0x90000300 as the default for ttyS0. To fix Linux we fix three things in the device tree: 1. Define stdout-path only one time for the first registered UART instead of incorrectly defining for each UART. 2. Change the UART alias name from 'uart0' to 'serial0' as almost all Linux tty drivers look for an alias starting with "serial". 3. Add the UART nodes so they appear in the final DTB in the order starting with the lowest address and working upwards. In summary these changes mean that the QEMU default UART (serial_hd(0)) is now setup where: * serial_hd(0) is the lowest-address UART * serial_hd(0) is listed first in the DTB * serial_hd(0) is the /chosen/stdout-path one * the /aliases/serial0 alias points at serial_hd(0) [1]: https://lore.barebox.org/barebox/707e7c50-aad1-4459-8796-0cc54bab32e2@pengutronix.de/T/#m5da26e8a799033301489a938b5d5667b81cef6ad [stafford: Change to serial0 alias and update change message, reverse uart registration order] Fixes: 777784bda468 ("hw/openrisc: support 4 serial ports in or1ksim") Cc: qemu-stable@nongnu.org Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Stafford Horne <shorne@gmail.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-ID: <20241203110536.402131-2-shorne@gmail.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
2024-12-03hw/openrisc: Fixed undercounting of TTCR in continuous modeJoel Holdsworth1-11/+15
In the existing design, TTCR is prone to undercounting when running in continuous mode. This manifests as a timer interrupt appearing to trigger a few cycles prior to the deadline set in SPR_TTMR_TP. When the timer triggers, the virtual time delta in nanoseconds between the time when the timer was set, and when it triggers is calculated. This nanoseconds value is then divided by TIMER_PERIOD (50) to compute an increment of cycles to apply to TTCR. However, this calculation rounds down the number of cycles causing the undercounting. A simplistic solution would be to instead round up the number of cycles, however this will result in the accumulation of timing error over time. This patch corrects the issue by calculating the time delta in nanoseconds between when the timer was last reset and the timer event. This approach allows the TTCR value to be rounded up, but without accumulating error over time.

2024-11-289pfs: fix 'Tgetattr' after unlinkChristian Schoenebeck1-1/+7
With a valid file ID (FID) of an open file, it should be possible to send a 'Tgettattr' 9p request and successfully receive a 'Rgetattr' response, even if the file has been removed in the meantime. Currently this would fail with ENOENT. I.e. this fixes the following misbehaviour with a 9p Linux client: open("/home/tst/filename", O_RDWR|O_CREAT|O_EXCL, 0600) = 3 unlink("/home/tst/filename") = 0 fstat(3, 0x23aa1a8) = -1 ENOENT (No such file or directory) Expected results: open("/home/tst/filename", O_RDWR|O_CREAT|O_EXCL, 0600) = 3 unlink("/home/tst/filename") = 0 fstat(3, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 This is because 9p server is always using a path name based lstat() call which fails as soon as the file got removed. So to fix this, use fstat() whenever we have an open file descriptor already. Fixes: 00ede4c2529b ("virtio-9p: getattr server implementation...")

2024-11-28amd_iommu: Fix kvm_enable_x2apic link error with clang in non-KVM buildsSairaj Kodilkar1-3/+5
Commit b12cb3819 (amd_iommu: Check APIC ID > 255 for XTSup) throws linking error for the `kvm_enable_x2apic` when kvm is disabled and Clang is used for compilation. This issue comes up because Clang does not remove the function callsite (kvm_enable_x2apic in this case) during optimization when if condition have variable. Intel IOMMU driver solves this issue by creating separate if condition for checking variables, which causes call site being optimized away by virtue of `kvm_irqchip_is_split()` being defined as 0. Implement same solution for the AMD driver.
