Strategic continuation of the flasher refactor: the SO no longer
generates or ships pre-built panel DTBOs. Users generate their own
mipi-panel.dtbo at https://arch-r.io/overlay-generator/ and drop it
into /flash/overlays/.
- config/overlays/README.txt rewritten with the same instruction in
6 languages (pt-BR, en, fr, es, zh, ru), one per line.
- u-boot/package.mk: removed the mipi-generator invocation and the
per-SUBDEVICE overlays_{original,clone,soysauce} install blocks.
Only the generic overlays/ dir (README) is shipped under
/usr/share/bootloader/.
- bootloader/mkimage: removed the RK3326-specific overlays_${SUBDEVICE}
and overlays_soysauce branches; the generic overlays/ copy at the
end of mkimage_dtb now covers RK3326 too.
- Deleted config/mipi-generator/ (generator.sh + archr-dtbo.py) and
config/archr-dts/ (vendor DTBs that were only consumed by the
generator).
Net: -8503 LOC + ~120 binary DTBs removed from the tree.
Issue archr-linux/Arch-R#35 (R36S Clone V20 batch 2551 sem áudio).
A DTS base rk3326-gameconsole-eeclone.dts NÃO inclui r3xs.dtsi —
diferente de rk3326-gameconsole-r36s.dts (original) e
rk3326-gameconsole-soysauce.dts (Y3506). Como r3xs.dtsi é onde o
node `rk817-sound` padrão fica ativo, o eeclone vai pro kernel só
com as duas variantes `rk817-sound-amplified` e `rk817-sound-simple`,
ambas com `status="disabled"`.
Para R36S Clone V20+ o vendor BSP 4.4 não publica `spk-con-gpio` nem
`rockchip,codec/spk-ctl-gpios` no rk817-sound (o widget de speaker
nem aparece no DTB), então a detecção atual do gerador caía no
ramo "keep default" e o overlay ficava sem habilitar nenhum sound
card. Resultado: `aplay -l` retornava "no soundcards found" em todo
clone V20 / V21.
generator.sh agora emite `sd_prefix="SDCLONE"` para subdevice=clone
(antes só emitia SDORIG para original/soysauce). archr-dtbo.py
trata SDCLONE como sinal de que a base DTS não tem default sound
card ativo e força o `rk817-sound-amplified` como fallback safe —
caso clone V20+ que carrega amp externo via GPIO não exposto no
DTB. Clones sem amp explícito (raros) podem usar a variante _SRs
para forçar `simple` ou o flag NAm para `spko-direct`.

The Y3506 family (V03/V04/V05 soysauce variants) ships without an
external speaker amplifier on the PCB; the rk817 SPKO line drives
the mono speaker directly. The vendor BSP 4.4 hides this with
hardcoded DAPM widgets and routes in rk817_codec.c, but mainline
ASoC respects the DT strictly, so the speaker stayed muted on every
Y3506 board even though the hardware path exists.
Changes:
config/archr-dts/rk3326-gameconsole-r36s.dts
Adds three pre-defined sound card variants with status=disabled:
rk817-sound-amplified (external amp gated by GPIO)
rk817-sound-simple (external amp on regulator, no GPIO gate)
rk817-sound-spko-direct (no external amp, SPKO straight to speaker)
The default rk817-sound stays active with the historic amp routing,
so any board the overlay generator cannot positively re-classify
keeps working as it did in v2.0-rc3.
config/mipi-generator/archr-dtbo.py
- Picks one of the three variants based on flags + vendor signals:
NAm flag -> spko-direct (Y3506 family)
spk-con-gpio / spk-ctl-gpios detected -> amplified
SRs flag without GPIO -> simple
otherwise -> keep base DTS default (amp routing)
- Accepts simple-audio-card,hp-det-gpio as a fallback to hp-det-gpio
so V05 boards that use the canonical mainline name are no longer
silently skipped by the audio block.
- Tolerates missing /pinctrl/headphone/hp-det in the vendor DTB
(some boards bind via the codec phandle only).
- Short-circuit branch (odroidgo3 + SDORIG) now still toggles the
sound card variant when NAm is set, so the six Soysauce batches
that go through that early return still get spko-direct.
- Fallback branch when the audio block crashes still applies
spko-direct when NAm is set (covers six Y3506 V03/V04 batches
where the vendor DTB omits hp-det-gpio entirely).
config/mipi-generator/generator.sh
- Appends NAm to every overlay generated under soysauce/, in
stable order with the existing SDORIG and variant flags.
Audit of all 44 vendor DTBs after the change:
18 clones -> default (amp routing preserved)
15 original -> default (amp routing preserved)
11 soysauce -> spko-direct (V03/V04/V05 all classes covered)
Reported by gemstoned via Discord: Soysauce V05 speaker would not
play under v2.0-rc3 even with HPi/SRs overlay flags toggled. Root
cause traced to (a) the variant nodes referenced by archr-dtbo.py
only existing in eeclone.dts and not in r36s.dts, and (b) the
vendor BSP rk817_codec.c hardcoded DAPM that mainline ASoC ignores.

The overlay generator now propagates board-specific hardware that the
previous version dropped on the floor:
- Amux selectors and per-button GPIO pin numbers (varies per subdevice:
clone uses 16/15/11, original 11/8/13, soysauce 13/12/17)
- button-adc tunings (deadzone/fuzz/flat) when vendor differs
- rumble-gpio (R36S V20 2025-05-18, GR36 — fixes "rumble stuck on")
- Panel status LEDs red/green/blue1/blue2 (8 soysauce V04+/V05 boards)
Adds an auto-discovery pass that propagates ANY remaining vendor
property not in our whitelist/blacklist, logging each propagation in
applied.txt so future board variants surface their quirks instead of
silently inheriting the original layout.
Blacklist preserves joypad-name/product/revision (ES gamecontrollerdb
match), per-button linux,code (vendor uses F-keys, ArchR uses standard
BTN_*) and PMIC regulator ranges (our base intentionally has expanded
ranges for the 1512MHz CPU OC).
- Enhanced `runemu.sh` to conditionally enable debug logging based on system log level, improving performance and debugging capabilities.
- Introduced functions to pause and resume background services during gameplay to optimize resource usage.
- Updated `retroarch.cfg` to disable frame delay and set video context driver to default, improving compatibility.
- Changed DuckStation's GPU renderer from OpenGL to Software for better performance on RK3326.
- Adjusted Flycast settings to lower resolution and optimize rendering settings for smoother gameplay.
- Modified MelonDS script to correctly handle internal resolution and screen orientation settings.
- Updated PPSSPP configuration to improve frame skipping behavior and adjusted CPU speed settings for better performance.
- Refined GPU driver scripts to handle panfrost availability and ensure proper driver binding, preventing graphical issues.
- Removed obsolete panfrost quirk file and migrated relevant settings to a new profile.d script for better management.
- Added service condition checks for various network daemons to ensure they only start if their configuration files exist.
- Adjusted systemd service configurations for network daemons to improve reliability and resource management.
- Updated sysctl settings to optimize memory management and reduce unnecessary RAM usage.
- Disabled debug shell service by default to enhance security and resource efficiency.
- Created necessary directories for mesa shader cache to ensure persistent shader caching across reboots.
- Added a new squashfs package for weston to support graphical environments.
Flasher verification:
- Move read-back SHA256 verification BEFORE boot partition modifications
(DTBO copy, variant write, extlinux switch). Previously verified AFTER
modifications, causing guaranteed hash mismatch (false positive).
- Remove duplicate verification block at end of script.
Kernel:
- Restore DRM_FBDEV_EMULATION=y (disabling it broke display on some setups
that depend on /dev/fb0 for initialization)
Panel overlays:
- Restore early return for odroidgo3-compatible devices in archr-dtbo.py.
R36S base DTS already has reset-gpios/power-supply/backlight - adding
them again in the overlay caused conflicts. Overlay only needs
panel-init-sequence and display timings.
- Regenerate all 32 DTBOs with correct behavior.

All 32 panel overlays regenerated after removing the premature return
in archr-dtbo.py. Panel 4 DTBO now correctly includes reset-gpios,
power-supply, and other hardware properties that were previously missing.
Panel 4 DTBO size: ~800 bytes → 4045 bytes (now includes full hardware config)

Critical fixes:
- archr-dtbo.py: Remove premature return for odroidgo3-compatible devices
that was skipping hardware property generation (reset-gpios, power-supply,
backlight-supply, enable-delay-ms). This is the ROOT CAUSE of Panel 4
wrong image and vibration issues reported by users.
- RetroArch: Switch from glcore to gl (more efficient on Panfrost/Mali-G31),
increase swapchain images from 2 to 3 (better frame pacing on Mali)
- DraStic: Disable hires_3d on ALL RK3326 configs (Mali-G31 lacks power for
high-res 3D rendering, was causing frame drops in NDS games)
- EmulationStation: Bump to latest with performance optimizations
