Move ALL paged-attention content out of the stock backend/cpp/llama-cpp backend and into backend/cpp/llama-cpp-localai-paged, so the stock backend is pure upstream llama.cpp and the paged backend owns and applies its own vendored patch series. - Delete the dead early-exploration scaffold backend/cpp/llama-cpp/paged/ (kernel/w4a16 Marlin scaffold, standalone paged_kv_manager, bench/loadgen, its own 0001-0002 patches, dense-era design docs, tests). Zero references repo-wide. - Move backend/cpp/llama-cpp/patches/ (the 28-patch paged series + paged/README + 3 operational docs, plus the kernel/ scaffold patch and the top-level paged README/BENCHMARKS) to backend/cpp/llama-cpp-localai-paged/patches/. The stock backend keeps no patches/ dir; it had no non-paged base patches. - Purify the stock backend: remove the LLAMA_PAGED make variable, the patches/paged apply loop, and the LLAMA_PAGED passthrough to prepare.sh; remove the paged-series handling from prepare.sh. The stock llama.cpp target now only clones the pin and applies its own (currently empty) base patches/ series. The runtime paged option hooks in the shared grpc-server.cpp are untouched (inert without the patches). - The paged backend's Makefile now applies its OWN patches/paged/0*.patch onto each freshly cloned tree via strict git apply (apply-paged-patches), after the copied stock infra clones the pin and applies base patches. - Repoint every reference to the old patches/paged path: the upstream canary workflow + apply script, bump_deps.yaml, gallery/index.yaml, the docs, backend/index.yaml, backend-matrix.yml, the top-level Makefile comments, and the moved PIN_SYNC / README docs. Drop the now-removed LLAMA_PAGED=on build-toggle from comments. Verified: the full 28-patch series applies strict-clean (git apply, exit 0) to a clean ggml-org/llama.cpp checkout at the pinned c299a92c, and the repointed canary apply script resolves and applies the series end to end.

# llama-cpp-localai-paged is LocalAI's paged-attention llama.cpp variant. It
|
|
# builds upstream llama.cpp with the LocalAI paged-attention patch series
|
|
# (patches/paged/, vendored in THIS backend) applied on top. It reuses
|
|
# backend/cpp/llama-cpp's grpc-server.cpp / CMakeLists.txt / prepare.sh / Makefile
|
|
# sources verbatim via a thin wrapper - the stock llama-cpp backend is pure
|
|
# upstream and carries NONE of the paged patches; this backend OWNS them.
|
|
#
|
|
# Pin handling (mirrors the turboquant wrapper, the precedent this is modelled
|
|
# on): the paged patch series is hand-verified bit-exact against ONE specific
|
|
# llama.cpp tip and re-exported by the manual PIN_SYNC process
|
|
# (patches/paged/PIN_SYNC_*.md). A naive pin bump would move the tip out from
|
|
# under the patches and break `git apply` at build time, so this backend OWNS
|
|
# its pin (LLAMA_VERSION below) instead of inheriting the auto-bumped stock pin
|
|
# from backend/cpp/llama-cpp/Makefile. The override is forced into every copied
|
|
# build via `LLAMA_VERSION=$(LLAMA_VERSION)`. There is deliberately NO
|
|
# bump_deps.yaml entry for it: it is advanced ONLY by PIN_SYNC, never nightly.
|
|
# (turboquant CAN auto-bump because its fork branch carries the patches; the
|
|
# paged series is vendored as .patch files here, so it cannot.)
|
|
#
|
|
# - NO patch-grpc-server.sh and NO apply-patches.sh: the shared grpc-server.cpp
|
|
# already carries the (runtime-gated) paged option hooks, and the paged patch
|
|
# series (patches/paged/) is applied by THIS Makefile's own apply step onto
|
|
# the freshly cloned tree, using the same strict `git apply` method the stock
|
|
# build uses for base patches. The stock llama-cpp Makefile applies only its
|
|
# own (currently empty) base patches/ series, never the paged one.
|
|
|
|
# Manually pin-synced llama.cpp tip the paged patch series is verified against.
|
|
# Decoupled from the auto-bumped stock pin in backend/cpp/llama-cpp/Makefile so
|
|
# the nightly llama.cpp bump cannot silently break the vendored paged patches.
|
|
# Advance ONLY via the PIN_SYNC process (rebase patches + bit-exact gate +
|
|
# re-export), then update this value. See:
|
|
# backend/cpp/llama-cpp-localai-paged/patches/paged/PIN_SYNC_*.md
|
|
#
|
|
# This pin = the manual, verified sync. The signal telling you WHEN to do the
|
|
# next sync is the early-warning canary
|
|
# (.github/workflows/llama-cpp-paged-canary.yml): weekly it applies + compiles
|
|
# this patch series against the latest upstream llama.cpp tip and goes red the
|
|
# moment upstream drifts past the patches. Canary red -> run a PIN_SYNC, then
|
|
# bump this value. The canary never touches this pin; it is signal-only.
