2024-08-06system/vl.c: Expand OpenGL related errorsPeter Maydell
Expand the OpenGL related error messages we produce for various "OpenGL not present/not supported" cases, to hopefully guide the user towards how to fix things. Now if the user tries to enable GL on a backend that doesn't support it the error message is a bit more precise: $ qemu-system-aarch64 -M virt -device virtio-gpu-gl -display curses,gl=on qemu-system-aarch64: OpenGL is not supported by display backend 'curses' Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> [AJB: Improved error report message] Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Message-ID: <20240731154136.3494621-3-peter.maydell@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
2024-08-06hw/display/virtio-gpu: Improve "opengl is not available" error messagePeter Maydell
If the user tries to use the virtio-gpu-gl device but the display backend doesn't have OpenGL support enabled, we currently print a rather uninformative error message: $ qemu-system-aarch64 -M virt -device virtio-gpu-gl qemu-system-aarch64: -device virtio-gpu-gl: opengl is not available Since OpenGL is not enabled on display frontends by default, users are quite likely to run into this. Improve the error message to be more specific and to suggest to the user a path forward. Note that the case of "user tried to enable OpenGL but the display backend doesn't handle it" is caught elsewhere first, so we can assume that isn't the problem: $ qemu-system-aarch64 -M virt -device virtio-gpu-gl -display curses,gl=on qemu-system-aarch64: OpenGL is not supported by the display (Use of error_append_hint() requires us to add an ERRP_GUARD() to the function, as noted in include/qapi/error.h.) With this commit we now produce the hopefully more helpful error: $ ./build/x86/qemu-system-aarch64 -M virt -device virtio-gpu-gl qemu-system-aarch64: -device virtio-gpu-gl: The display backend does not have OpenGL support enabled It can be enabled with '-display BACKEND,gl=on' where BACKEND is the name of the display backend to use.

2024-08-06hw/ide/pci: Remove dead code from bmdma_prepare_buf()Peter Maydell
Coverity notes that the code at the end of the loop in bmdma_prepare_buf() is unreachable. This is because in commit 9fbf0fa81fca8f527 ("ide: remove hardcoded 2GiB transactional limit") we removed the only codepath in the loop which could "break" out of it, but didn't notice that this meant we should also remove the code at the end of the loop. Remove the dead code.

2024-08-06hw/block/fdc-isa: Assert that isa_fdc_get_drive_max_chs() found somethingPeter Maydell
Coverity complains about an overflow in isa_fdc_get_drive_max_chs() that can happen if the loop over fd_formats never finds a match, because we initialize *maxc to 0 and then at the end of the function decrement it. This can't ever actually happen because fd_formats has at least one entry for each FloppyDriveType, so we must at least once find a match and update *maxc, *maxh and *maxs. Assert that we did find a match, which should keep Coverity happy and will also detect possible bugs in the data in fd_formats.

2024-08-06hw/ide/atapi: Be explicit that assigning to s->lcyl truncatesPeter Maydell
In ide_atapi_cmd_reply_end() we calculate a 16-bit size, and then assign its two halves to s->lcyl and s->hcyl like this: s->lcyl = size; s->hcyl = size >> 8; Coverity warns that the first line here can overflow the 8-bit s->lcyl variable. This is true, and in this case we're deliberately only after the low 8 bits of the value. The code is clearer to both humans and Coverity if we're explicit that we only wanted the low 8 bits, though.

2024-08-06hw/block/pflash_cfi01: Don't decrement pfl->counter below 0Peter Maydell
In pflash_write() Coverity points out that we can decrement the unsigned pfl->counter below zero, which makes it wrap around. In fact this is harmless, because if pfl->counter is 0 at this point we also increment pfl->wcycle to 3, and the wcycle == 3 handling doesn't look at counter; the only way back into code which looks at the counter value is via wcycle == 1, which will reinitialize the counter. But it's arguably a little clearer to break early in the "counter == 0" if(), to avoid the decrement-below-zero.

2024-08-06target/riscv: Add asserts for out-of-bound accessAtish Patra
Coverity complained about the possible out-of-bounds access with counter_virt/counter_virt_prev because these two arrays are accessed with privilege mode. However, these two arrays are accessed only when virt is enabled. Thus, the privilege mode can't be M mode. Add the asserts anyways to detect any wrong usage of these arrays in the future.

2024-08-06target/riscv: Relax fld alignment requirementLIU Zhiwei
According to the risc-v specification: "FLD and FSD are only guaranteed to execute atomically if the effective address is naturally aligned and XLEN≥64." We currently implement fld as MO_ATOM_IFALIGN when XLEN < 64, which does not violate the rules. But it will hide some problems. So relax it to MO_ATOM_NONE.

2024-08-02migration/multifd: Fix multifd_send_setup cleanup when channel creation failsFabiano Rosas
When a channel fails to create, the code currently just returns. This is wrong for two reasons: 1) Channel n+1 will not get to initialize it's semaphores, leading to an assert when terminate_threads tries to post to it: qemu-system-x86_64: ../util/qemu-thread-posix.c:92: qemu_mutex_lock_impl: Assertion `mutex->initialized' failed. 2) (theoretical) If channel n-1 already started creation it will defeat the purpose of the channels_created logic which is in place to avoid migrate_fd_cleanup() to run while channels are still being created. This cannot really happen today because the current failure cases for multifd_new_send_channel_create() are all synchronous, resulting from qio_channel_file_new_path() getting a bad filename. This would hit all channels equally. But I don't want to set a trap for future people, so have all channels try to create (even if failing), and only fail after the channels_created semaphore has been posted. While here, remove the error_report_err call. There's one already at migrate_fd_cleanup later on.
