Let me go through the information provided step by step. + +The problem described is that a Leopard image boots on a G4 but not on a G5 when using QEMU with the -cpu 970 or 970FX option. The symptoms include early hangs and specific error messages about invalid SPR (Special Purpose Register) accesses, such as trying to read or write SPRs like 276 (0x114), 277 (0x115), and 304 (0x130). + +The user mentioned that they added support for SPR 304 in target/ppc/cpu_init.c but the issue still persists. They also referenced the SCOM Facility documentation, which is related to how the PowerPC 970FX handles certain processor core operations through these SPRs. + +Looking at the email sent to the qemu-ppc list, it seems like they are dealing with low-level initialization code in the XNU kernel for OS X. The provided link points to an assembly file that's part of the OS startup process, which is definitely system-level code. + +The error messages indicate issues during boot when trying to access these SPRs, suggesting problems at a very low level—probably before user-mode processes even start. Since this is happening in the kernel space, it's related to how QEMU emulates the system hardware and registers, not something a user application would cause. + +Additionally, the fact that it's about emulate certain CPU instructions and SPR handling falls under system emulation, which is part of the hypervisor or emulator's responsibilities. This isn't something a regular user application would interact with directly; it's more about how the virtualized environment is set up. + +So putting this all together, the issue seems to be related to the QEMU emulator's ability to correctly simulate the PowerPC 970FX architecture, particularly in handling specific SPRs that are crucial for booting the OS. This is a problem at the system level because it affects the operating system's initialization and hardware interaction. +</think> + +system \ No newline at end of file |
