v0.4.3-beta

memory: switch to upstream 4a2221d payload with packed reads

Install the newer pan-Rijovich payload (764 B code + 144 B BSS), the same
build a custom BIOS installs, instead of the old 176 B single-chip build.

• patcher: check the SMU firmware version (0x00580600) and require an
  entirely zero payload region before unlocking; upload code with zeroed
  BSS, verify the readback, then hook Q3/6 and Q3/7, and Q3/5 last
• recognize the payload by code hash plus all three hooks; the original and
  bounded builds are still accepted when a BIOS installs them
• collector: read all eight chips with two packed Q3/6 requests and report
  firmware read timeouts per chip and stage
• retry the guard left by a reader-only rejection of an unknown payload,
  since that path never writes to SMU
• installer: firmware-modern probe result selects reader-only
• bundle the upstream bin/symbols/source and drop the ELF; update docs/tests

v0.3 - Add GDDR6 memory temperature monitoring

Add GDDR6 memory temperature monitoring

Adds optional GDDR6 memory temperature monitoring for BC-250, based on pan-Rijovich/bc250-memory-temperature (MIT, see memory/UPSTREAM.md).

How it works: a separate root service (bc250-memory.service) patches SMU at startup and polls all 8 GDDR6 chips every 3s, writing a small snapshot file. The main apu_telemetry daemon validates and folds that snapshot into the existing /run/apu_telemetry.json / /api/telemetry output as a memory object — no JSON parser needed on the daemon side. All SMU/firmware-patching code stays isolated in the separate service; the always-privileged daemon only ever reads a plain text file.

What's included:

• memory/ — the SMU patch/collector service (Python, stdlib only), with platform/payload validation and a per-boot operation guard against retrying a wedged SMU
• memory_telemetry.h — parses and validates the collector's snapshot (bounds-checked, degrades to unavailable/stale on any anomaly)
• Installer: --memory-temp / --no-memory-temp flags + interactive prompt, uninstall cleanup
• Dashboard v2: memory panel with per-chip readings, board halos, hotspot/average, hidden entirely when the service isn't installed
• Dashboard v1 (classic): compact GDDR6 row + per-chip grid in "Other sensors"
• MangoHud / CoolerControl: hotspot + average exposed via /run/bc250/memory_*
• Tests: tests/test_memory.py (offline, fake SMU/PCI/DMA), tests/test_v2_memory.js

Fully optional and backward-compatible: the memory field is always present in the API; when the collector isn't installed, both dashboards simply hide the panel instead of showing an empty widget.

v0.2.0

Highlights

• CPU/GPU fault & warning badges — the dashboard now surfaces PMBus fault/warning bits directly on the CPU and GPU status tiles instead of only in raw JSON.
• CoolerControl & MangoHud file sensors for VRM temps/power — CPU/GPU VRM temperatures and PMBus rail data (VIN, per-rail VOUT/IOUT/POUT, total power) are now exported under /run/bc250, ready to wire up as CoolerControl Custom Sensors → File or a MangoHud overlay via the new mangohud/MangoHud-bc250.conf snippet.
• v2 dashboard: selectable chart window — the animated board-diagram view now lets you switch the live chart's time window between 30s / 1m / 2m.
• Redrawn board illustration — the v2 board diagram (PCB, heatsink, M.2 drive, VRM chokes) is redrawn to match the real BC-250 board dimensions.

What's Changed

• Redraw the board illustration to the real board dimensions by @tri3gubki-ops in #5
• v2: selectable chart window (30s / 1m / 2m) by @tri3gubki-ops in #6
• Implement fault and warning badges for CPU/GPU status in UI by @onlinermm in #7
• Add /run/bc250 external sensors for CoolerControl and MangoHud by @primus192 in #8

New Contributors

• @tri3gubki-ops made their first contribution in #5
• @primus192 made their first contribution in #8

Upgrading

Download bc250-telemetry.tar.gz from this release, extract, and run ./install.sh as usual (see README). No config migration needed — new /run/bc250 sensor files appear automatically if PMBus/I2C is available; existing CoolerControl/MangoHud configs keep working unchanged.
