The user is reporting a bug in QEMU related to an assertion failure in the function pgb_reserved_va. The error message mentions that the assertion `addr == test' failed. They provided some context about compiling QEMU on CentOS 7.5 with RISC-V 32-bit user mode. + +First, the initial compile error was about FALLOC_FL_KEEP_SIZE being undeclared. They fixed that by adding an include for linux/falloc.h. That part seems like a build issue, but the main problem is the runtime assertion failure. + +Looking at the runtime error, the backtrace shows that after an mmap call, the address returned (test) isn't equal to the expected addr. The assertion is checking if the mapped address matches a specific value. The user suggests that mmap might not guarantee the address, leading to the failure. + +The function pgb_reserved_va is in elfload.c, which handles loading ELF binaries. The assertion is likely ensuring that the mmap'ed address aligns with what's expected for the guest's virtual address space. If mmap doesn't return the requested address, the assertion fails. This seems to be a problem with how QEMU is handling memory mapping for the user-mode emulation. + +Since the issue is happening during execution (runtime) of the QEMU process, and it's related to system calls (specifically mmap), but the core problem is that the assertion is failing due to the behavior of mmap not meeting QEMU's expectations. The assertion is part of QEMU's logic to reserve a virtual address space, and when the actual address from mmap doesn't match, it triggers the error. + +The categories to choose from are instruction, syscall, or runtime. The problem isn't about a specific instruction being faulty. It's related to a syscall (mmap) but the error isn't about the syscall itself failing, but rather the logic in QEMU expecting a specific address from the syscall. The assertion failure occurs at runtime because the assumption about the mmap address is incorrect. So the category is runtime. +</think> + +runtime \ No newline at end of file |
