Wraps every cgoLatticeOps.* / cgoCryptoOps.* method in ops_c.go with translateCapiError so capi.ErrInvalidArgument is normalized to accel.ErrInvalidArgument before reaching the public surface. Closes the chain-wide sentinel-identity mismatch that defeated every errors.Is(err, accel.ErrInvalidArgument) M-1 propagation check. Probe 7: CPU stubs now return ErrCPUNotImplemented instead of silent false verdicts. Probe 10: Added integration_invalid_argument_test.go under -tags lux_accel_real exercising the cgo boundary directly.

//go:build cgo && lux_accel_real

// Package capi real-build link directives.
|
|
//
|
|
// One and only one of `stub_default.go` or `real.go` is in any given
|
|
// build. The selector is the `lux_accel_real` build tag — see the
|
|
// header comment on stub_default.go for the design rationale.
|
|
//
|
|
// This file holds exactly two things:
|
|
//
|
|
// 1. `#cgo LDFLAGS: -lluxaccel` — link the binary against the real
|
|
// native library. Combined with the `-L` search paths and rpaths
|
|
// already declared in capi.go, the dynamic loader finds
|
|
// libluxaccel.{so,dylib} at one of:
|
|
//
|
|
// /usr/local/lib (canonical Linux install)
|
|
// /opt/homebrew/lib (Apple Silicon Homebrew)
|
|
// ${SRCDIR}/../../../../luxcpp/install/lib (local checkout)
|
|
//
|
|
// 2. `#include <lux/accel/c_api.h>` — declares every `lux_*` entry
|
|
// point as a normal (non-weak) extern. capi.go calls these from
|
|
// Go via cgo wrappers; under this build tag the wrappers resolve
|
|
// directly to libluxaccel's strong definitions, with no stub
|
|
// bodies anywhere in the binary.
|
|
//
|
|
// Required host install (verified at boot via accel.Available()):
|
|
//
|
|
// Linux : /usr/local/lib/libluxaccel.so.0.1.2 (plus CUDA plugin
|
|
// under $LUX_PLUGIN_PATH or /usr/local/lib/lux/plugins/)
|
|
// Darwin : /opt/homebrew/lib/libluxaccel.dylib (plus Metal plugin
|
|
// under /opt/homebrew/lib/lux/plugins/ or ~/.lux/plugins/)
|
|
//
|
|
// libluxaccel is self-contained: it links libluxgpu + libluxcrypto
|
|
// statically at build time inside luxcpp. Go consumers only need
|
|
// `-lluxaccel`.
