86 of the 144 margin channels moved up +0.8% .. +2.5% to the measured
median for this platform (3.3 -> 3.38, 0.9 -> 0.915, 0.8 -> 0.82, ...).
That is not a display change. VNOM is the denominator of margin_status'
deviation %, and it is also the basis margin_set derives high/low/OV/UV
from - so both the number you read and the voltage you apply move with
it. A rail steady at 0.756 V used to read +0.80% against a nominal 0.75
and now reads 0.00%. Margin logs from before and after cannot be
compared: the reference moved, the hardware did not.
comboA/comboB are replaced by combo_SWB_CONN13..16_{high,low}. The
per-channel percentages are positional, so they follow the rails of one
specific board - applying a CONN13 profile to a CONN16 margins the wrong
rails and nothing detects it. SWB0 and SWB1 share a profile per CONN
because their rails are identical.
Fixes two things the deletion broke:
- margin_apply_profile_all.sh still named comboA for all nine boards,
which would now stop at "Profile not found" nine times over. It names
the matching per-CONN profile instead, with CB on the generic
combo_high3, and a note that the low pass is _high -> _low.
- docs/LTC2980_channel_map.csv is generated from settings/*.conf, so
all 86 changed rails were stale in it. Regenerated.
The eight new profiles also still carried comboA's header comment
("alternating high/low"), which describes neither what they contain nor
what they are for.
Script A -> V1.1.3.
