v3: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg02907.html v3 -> v4: Hide InteractiveConsole behind QEMU_TEST_INTERACTIVE (Alex). Probe /proc/self/mem in the PROT_NONE test. v2: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg01592.html v2 -> v3: Add Richard's R-b on [1/3]. Fix printing the architecture name and the number of failures in test_gdbstub.py. Patches that need review: [2/3] and [3/3]. v1: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg01314.html v1 -> v2: Use /proc/self/mem as a fallback. Handle TB invalidation (Richard). Test cross-page accesses. RFC: https://lists.gnu.org/archive/html/qemu-devel/2023-12/msg02044.html RFC -> v1: Use /proc/self/mem and accept that this will not work without /proc. Factor out a couple functions for gdbstub testing. Add a test. Hi, I've noticed that gdbstub behaves differently from gdbserver in that it doesn't allow reading non-readable pages. This series improves the situation by using the same mechanism as gdbserver: /proc/self/mem.
