The problem is about executable PMP regions less than 4K causing instruction access faults in QEMU. + +PMP stands for Physical Memory Protection, which is part of the RISC-V architecture. It's used to control memory permissions like execute, write, and read at different privilege levels. Since PMP deals with memory protection, it's related to how the CPU interacts with memory, which sounds more like a system-level concern. + +The issue arises when trying to execute code in a region that's smaller than 4K. TCG is QEMU's translation cache generator, so this problem affects how instructions are translated and executed. The function `get_page_addr_code_hostp` tries to fetch a whole page but fails because the PMP region isn't large enough, leading to an exception. + +The user mentioned that changing this part of TCG could affect other architectures, so it's a more internal QEMU issue rather than something related to user applications. Since PMP and TLB (Translation Lookaside Buffer) operations are low-level hardware interactions, this seems like a system-mode problem involving CPU privileges and memory management. + +Additionally, the bug affects how the virtual machine handles instruction execution at a lower level, which is part of the system's operation rather than user applications. So it's more about the system mode. +</think> + +system \ No newline at end of file |
