The zlib guest thunk\nlibrary (GTL) uses this protocol to forward selected zlib calls to host-side\nHTL/native zlib.\n\nCompared to v1 [1], this version narrows scope:\n\n- drop the callback/qsort prototype\n- drop extra demo variants\n- keep only a single plugin + single matching example that is easy to build\n and reproduce\n\nBuild/repro documentation is provided in:\n\n- docs/about/emulation.rst\n- contrib/plugins/passthrough-examples/README.rst\n\nThanks,\nXU Kailiang\n\n[1]: https://lore.kernel.org/qemu-devel/20260331173656.35305-1-xukl2019@sjtu.edu.cn/T/#t\n\n---\n\nXU Kailiang (1):\n contrib/plugins: add syscall-filter passthrough zlib demo\n\n contrib/plugins/meson.build | 11 ++\n contrib/plugins/passthrough-examples/Makefile | 23 +++\n .../plugins/passthrough-examples/README.rst | 60 +++++++\n .../plugins/passthrough-examples/meson.build | 19 ++\n .../passthrough-examples/passthrough-gtl.c | 41 +++++\n .../passthrough-examples/passthrough-gtl.h | 17 ++\n .../plugins/passthrough-examples/zlib-demo.c | 90 ++++++++++\n .../plugins/passthrough-examples/zlib-gtl.c | 72 ++++++++\n .../plugins/passthrough-examples/zlib-htl.c | 37 ++++\n contrib/plugins/passthrough-protocol.h | 14 ++\n contrib/plugins/passthrough.c | 162 ++++++++++++++++++\n docs/about/emulation.rst | 33 ++++\n 12 files changed, 579 insertions(+)\n create mode 100644 contrib/plugins/passthrough-examples/Makefile\n create mode 100644 contrib/plugins/passthrough-examples/README.rst\n create mode 100644 contrib/plugins/passthrough-examples/meson.build\n create mode 100644 contrib/plugins/passthrough-examples/passthrough-gtl.c\n create mode 100644 contrib/plugins/passthrough-examples/passthrough-gtl.h\n create mode 100644 contrib/plugins/passthrough-examples/zlib-demo.c\n create mode 100644 contrib/plugins/passthrough-examples/zlib-gtl.c\n create mode 100644 contrib/plugins/passthrough-examples/zlib-htl.c\n create mode 100644 contrib/plugins/passthrough-protocol.h\n create mode 100644 contrib/plugins/passthrough.c\n\n\nbase-commit: b6a7d06213e5d2f7d124d16418bc289c4a8a4b82"}
