Let me break down the information provided. + +The user is experiencing an issue where their arm64 defconfig kernel (version 4.14.275) no longer boots after implementing FEAT_LPA in TCG. They've done some bisecting and found that the commit introducing FEAT_LPA is causing the problem. The problematic commit is 7a928f43d, which implements FEAT_LPA. + +They mention that using `-cpu max` or `-cpu max,lpa2=off` results in a hang with no output after this change. However, before implementing FEAT_LVA (commit 0af312b6), the same setup worked fine. + +The user also notes that a newer kernel (4.19.237) works correctly with `-cpu max` or `-cpu max,lpa2=off`. They're wondering if this behavior is expected due to the older kernel's age, suggesting they might need to use a different CPU type like `cortex-a72` for compatibility. + +Now, considering QEMU's architecture: system-mode emulation involves simulating an entire system, including devices, peripherals, and handling lower-level operations. User-mode typically refers to processes running in user space without full hardware simulation. + +Since the issue pertains to kernel booting and CPU features (FEAT_LPA), this is related to how the virtualized environment interacts with the guest OS's low-level initialization. This involves system-level configurations and device emulation, which are handled in QEMU's system-mode. The problem isn't about a specific userland application but rather the interaction between the kernel and the emulated hardware. + +Therefore, the bug seems to be related to how QEMU is handling certain CPU features or configuration during boot, which affects the entire system operation. Hence, it falls under system-mode. +</think> + +system \ No newline at end of file |
