Let me start by understanding what's going on here. + +The issue is about ARM's HSTR register not routing traps correctly in QEMU. Specifically, when running at EL1 with HSTR.T12 set, it should trigger an exception to EL2 (HypTrapException 0x3), but instead, the CPU is routed to EL1's undefined exception. + +Looking at the provided pseudo code from ARM's documentation, I see that when in EL1 and certain conditions are met (like EL2 enabled and HSTR settings), it should take a trap to EL2. But in the test program, this isn't happening; instead, an undefined exception occurs at EL1. + +The bug report mentions that QEMU's implementation is inconsistent with ARM's documentation. This suggests there's an issue in how QEMU handles system register accesses and exception routing. + +Now, looking at the categories: possible options include 'hypervisor', 'kernel', 'boot', etc. The HSTR is part of the system registers used for exception handling across different Exception Levels (ELs). EL2 is typically Hypervisor level, so any issue in trapping to EL2 would relate to hypervisor functions. + +Since QEMU emulates the hypervisor environment when virtualization is enabled (as seen in the test command with 'virtualization=on'), the problem likely stems from how QEMU handles these traps during hypervisor operations. The incorrect routing means that instead of transitioning to the higher Exception Level (EL2), it's staying within EL1, which is a misconfiguration in the hypervisor layer. + +Therefore, this issue falls under the category of 'hypervisor' because it pertains to the handling of exceptions and system registers at different exception levels, specifically when interacting with the hypervisor's trap mechanisms. +</think> + +hypervisor \ No newline at end of file |
