The issue is about running a PowerPC64 little-endian Linux build under QEMU's user emulation with 64KiB pages, and it started failing when moving from Ubuntu Focal (which had QEMU v4.2) to Jammy (with QEMU v6.2). The problem seems to be that the test is getting a SIGSEGV with SEGV_MAPERR at an address that was supposed to be mapped by an mmap call. + +Looking at the details, the user provided a backtrace showing where the signal occurs and some syscalls leading up to it. They also mentioned that bisecting points to a specific commit in QEMU, but they think that's just exposing an underlying bug rather than being the root cause. + +I need to determine if this is classified under 'instruction', 'syscall', or 'runtime'. + +First, 'instruction' would involve issues with how instructions are executed. If QEMU misinterpreted a PowerPC64 instruction leading to incorrect memory access, that could be it. But the bug report doesn't mention any specific instruction causing problems; instead, it's about segmentation faults after mmap calls. + +Next, 'syscall' relates to errors when handling system calls. The user shows that an mmap call was successful but then a subsequent access leads to SIGSEGV. Maybe QEMU is mishandling the mmap or the mapping of memory pages in 64KiB chunks, which could be a syscall issue. + +Then there's 'runtime', which covers other runtime errors not directly tied to instructions or syscalls. If the problem is due to how QEMU manages memory mappings or page tables during emulation, that would fall under runtime issues. + +Considering that the error occurs after an mmap and accessing the mapped area results in SIGSEGV, it suggests a problem with how the pages are managed in QEMU's user-mode emulation. This could be related to how 64KiB pages are handled compared to smaller pages. Maybe there's a bug in how QEMU translates or manages these larger pages when emulating the PowerPC architecture under Linux. + +So, is this an issue with how system calls like mmap are being translated (syscall) or more about the memory management and page handling at runtime? It seems more likely related to runtime because it involves the state of memory after a syscall. The fact that the address was mapped but then access fails suggests an error in maintaining the correct mappings, which would be part of the runtime environment setup by QEMU. + +Therefore, I think this should fall under 'runtime' errors. +</think> + +runtime \ No newline at end of file |
