I know that the MMU (Memory Management Unit) deals with translating virtual addresses to physical addresses, which is a low-level operation managed by the CPU. + +The code snippets show assembly instructions like TLBI VAE1 and accessing TTBR0_EL1. From what I remember, EL1 refers to Exception Level 1 in ARM architecture, which is typically the operating system's execution level. So this is definitely dealing with higher privileges because user-mode applications don't have access to these registers. + +The user mentions that they had to change the TTBR0_EL1 as a workaround in QEMU 2.12 and now it's not working in QEMU 3.1. Since TTBR0_EL1 is part of the system registers, this points towards a system-level issue rather than something related to user applications. + +Also, MMU operations like invalidating caches or modifying page tables are usually done by the OS kernel, which runs in system mode. The fact that changing TTBR0_EL1 worked as a workaround suggests it's a problem with how QEMU handles these low-level operations, possibly affecting the state of the MMU that the guest OS relies on. + +In summary, since this involves system registers and MMU handling at EL1, it's a system-mode issue. +</think> + +system \ No newline at end of file |
