The user is reporting an issue with QEMU where they can't allocate more than about 2GB of memory on a 32-bit platform using qemu-user. The problem seems to be related to the pageflags_find and pageflags_next functions in the user-exec.c file. The user mentions that the third parameters of these functions should be target_ulong instead of target_long, which is causing a signed extension when converted to uint64_t. + +Hmm, so the issue is about memory allocation beyond 2GB. On 32-bit systems, the address space is limited, but some architectures can support up to 4GB. The problem here is that when trying to allocate more than 2GB, it fails. The user provided a test program using malloc in a loop, which fails after the first 2GB. The root cause seems to be in how the parameters are handled in those functions. Using target_long (which is signed) instead of target_ulong (unsigned) might lead to incorrect handling of addresses when they are in the upper 2GB range, since signed extensions can cause the values to be interpreted as negative, leading to errors in memory management. + +So, the error is not directly related to a syscall, like malloc itself, but rather an internal runtime error in QEMU's code when managing memory addresses. The mistake is in the data types used, leading to incorrect address handling. Therefore, this would fall under a runtime error because it's an issue within QEMU's execution logic, not an instruction or syscall problem. +</think> + +runtime \ No newline at end of file |
