# Foundry Blackhole backend — Phase 6's ROPE op (partial NeoX rotary position embedding).
|
|
#
|
|
# TWO BINARIES, TWO BUILD TREES, AND THE FENCE BETWEEN THEM IS THE POINT.
|
|
#
|
|
# make -f Makefile.rope all -> build-rope/test_rope_ops
|
|
# The OFF-HARDWARE gate. Built WITHOUT -DFT_TT_PHASE1B_NOC_ENABLED, so every device call
|
|
# in the objects it links returns FT_TT_EPERM before touching the NoC. That is not a
|
|
# formality: it means this binary cannot reach the card even if it is wrong, which is
|
|
# what makes it safe to run while somebody else owns the silicon.
|
|
#
|
|
# make -f Makefile.rope PHASE1B=1 card -> build-rope-card/test_phase6_rope
|
|
# The ON-CARD acceptance. PHASE1B=1 is mandatory and deliberate (spec §7.3 — a wrong NoC
|
|
# coordinate hangs the chip and costs a physical power cycle).
|
|
#
|
|
# The two trees are separate because the flag changes what the backend objects DO. Sharing a
|
|
# tree would mean a stale object from the other configuration linking silently, which is not
|
|
# a build error — it is a wrong answer (dev notes §5, best-practices §9).
|
|
#
|
|
# Run the off-hardware gate from this directory, so FT_TT_KERNEL_DIR's default resolves:
|
|
# ./build-rope/test_rope_ops
|
|
#
|
|
# Run the on-card acceptance (detached, and never with these cores in use by another worker):
|
|
# FT_TT_FIRMWARE_DIR=../programs/rope FT_TT_TENSIX_INDEX=40 \
|
|
# ./build-rope-card/test_phase6_rope ../programs/rope
|
|
#
|
|
# The program directory is a RELOCATE_KERNEL_TEXT=1 build:
|
|
#
|
|
# RELOCATE_KERNEL_TEXT=1 READER_CTARGS=0,1,2,3,2048,1 COMPUTE_CTARGS=0,1,2,3,4,5,16,1 \

|
|
#
|
|
# It must be built against the SAME firmware build as anything else loaded on that core: a
|
|
# kernel is linked against its own firmware's exported symbols, so mixing directories is a
|
|
# wedged core, not a configuration.
