Let's read through the details carefully. + +The issue is that `qemu-system-arm` isn't honoring CPACR.ASEDIS and D32DIS. The user found that some SIMD instructions are considered undefined on a Raspberry Pi 2B but run successfully in QEMU. They compiled the kernel with specific options, and during testing, certain instructions like VMAX_int_T1A1_A, VMUL_scalar_A1_A, etc., were executed without issues in QEMU even though they should be undefined. + +Looking at the description, it mentions that CPACR.ASEDIS is set to 1, which according to the ARM manual, disables Advanced SIMD functionality. This means any non-VFPv3/VFPv4 SIMD instructions should be undefined when accessed from PL1 and PL0 modes. + +The user also provided a test case where they hook an undefined handler in the kernel module to catch these instructions. When running on QEMU, these instructions aren't being caught, implying that QEMU isn't correctly enforcing the CPACR settings and thus not marking them as undefined when it should. + +In terms of classification, I need to consider the possible categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, or other. + +The bug seems related to how QEMU handles certain instructions based on CPU configuration. Specifically, it's about whether the emulator correctly respects the CPACR settings which control SIMD functionality. This isn't directly a translation issue (like mistranslation) but rather a missing check in the instruction handling code. + +Looking at the target files mentioned (`target/arm/translate-neon.c`), it suggests that there might be an omission in checking the CPACR flags before executing these instructions. So, QEMU is allowing execution of SIMD instructions even when they should be disabled based on the CPACR settings. + +Since this relates to how the emulator handles specific instruction sets and CPU features, and not directly tied to any other category like network or graphics, it falls under 'mistranslation'. Mistranslation in this context refers to incorrect semantic mapping from the source architecture (ARM) to the target's IR, leading to instructions being treated as valid when they should be undefined. + +Therefore, the appropriate category for this bug report is 'mistranslation'. +</think> + +mistranslation \ No newline at end of file |
