Let me read through the details carefully. - -The user is working on an Aarch64 system using QEMU version 3.1. They're trying to remove permissions from a 4KiB MMU descriptor and then invalidating it with the TLBI VAE1, x0 instruction. This worked around in QEMU 2.12 by manipulating TTBR0_EL1, but now it's not working in QEMU 3.1. - -So, they used to use a workaround where they changed the TTBR0_EL1 register to trick QEMU into reloading descriptors. But since updating to QEMU 3.1, this method fails. - -Looking at the categories provided: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. - -The issue is related to MMU descriptors and TLB invalidation, which points towards memory management. However, the user's workaround involved modifying TTBR0_EL1, a system register, suggesting that QEMU might not be handling certain TLB operations correctly after some changes in version 3.1. - -This seems like it could be an issue with how QEMU handles memory translation or TLB invalidation. Maybe there was a change in the hypervisor's handling of MMU state that broke this particular workaround. Alternatively, perhaps the way descriptors are invalidated changed between versions. - -Since the problem is related to QEMU's behavior when manipulating system registers and descriptors, it seems more aligned with how the hypervisor (QEMU as the emulator) handles virtual memory. So, the category 'hypervisor' makes sense here because it involves the management of MMU state and TLB operations under emulation by QEMU. - -I don't think it fits into 'mistranslation' since that's usually about incorrect mapping from source to target. It doesn't seem like an assembly lowering issue either. The other categories like device or network aren't directly related here. -</think> - -hypervisor \ No newline at end of file |
