The user provided a detailed description of the issue they're encountering. - -The problem involves AArch64 instructions where the ISV bit in ESR_EL2 is set to 1 when it shouldn't be. Specifically, they mention post-indexed instructions like `str w3, [x6], #4` and `ldrb w1, [x0, #1]!`. According to the ARM manual, ISV should be 0 for these types of faults except in specific cases. - -The user compared QEMU's behavior to hardware where ISV is correctly set to 0. They also provided steps to reproduce, involving running a hypervisor and causing a data abort. The issue seems related to how QEMU handles exceptions in the hypervisor context (EL2). - -Looking at the categories: Mistranslation refers to incorrect mapping from source to target, which might fit if it's an assembly lowering issue. But the problem here is about ESR_EL2 register handling during faults. - -Other possible categories include device, network, kernel, etc., but this seems more related to how exceptions are handled in the hypervisor mode. The key point is that QEMU is incorrectly setting ISV for certain data aborts, which falls under exception handling rather than translation or performance issues. - -Therefore, the category should be 'hypervisor' because it pertains to the behavior of the hypervisor (EL2) when handling guest exceptions. -</think> - -hypervisor \ No newline at end of file |
