Let's see what the problem description says. + +The user is using QEMU with the CPU model "max" and has disabled SVE (SVE=off). They found that QEMU crashes during boot when SVE is completely disabled, but it works fine if SVE isn't disabled or if only SVE128 is enabled. The crash happens early in kernel startup, right after GRUB loads the kernel and initrd. + +Looking at the backtrace provided: + +- It starts with a pthread_kill implementation, then raise, abort, etc., leading into QEMU's code. +- The function sve_vqm1_for_el_sm is where the assertion fails. This seems related to SVE handling in the ARM target helper functions. +- The call stack goes through various parts of QEMU's TCG (Translation-Caching Translator) and CPU execution loops. + +I know that user-mode emulation typically deals with running unprivileged code, while system-mode handles higher-level operations like device emulation and kernel booting. Since this crash is happening during the boot process when the kernel starts executing, it seems to be related to how QEMU initializes or interacts with the virtualized CPU features, particularly SVE. + +SVE (Scalable Vector Extension) is a CPU feature that affects how vector instructions are handled. Disabling it might require certain configurations in the CPU model. The error suggests there's an assertion failure when trying to handle SVE state for exception levels, possibly because some setup isn't done correctly when SVE is disabled. + +Given that this happens during kernel execution and involves low-level CPU helper functions, it's more likely a system-mode issue. System-mode deals with the overall system state, including initializing CPUs and handling their features, which seems to be where the problem arises. +</think> + +system \ No newline at end of file |
