MAILBOX (fully open A7<->RISC-V SCR1 round-trip, 5/5 exact echoes on c8a3):
- rockchip-mailbox.c: rv1106 has 1 shared IRQ, not 4/channel -> added
rv1106_drv_data{num_chans=1} + compatible (rk3368 fallback assumed 4 -> probe
failed 'IRQ index 1 not found').
- clk-rv1106.c: CLK_CORE_MCU (SCR1 core clock) marked CLK_IGNORE_UNUSED -
6.18's clk_disable_unused() was switching off the coprocessor clock so a
loaded firmware never ran (5.10 left it on).
- Open SCR1 echo firmware (scr1-echo/, 154B RV32IMC) + load/test scripts;
A2B_INTEN on the MCU side + CMD-then-DAT (DAT=doorbell) order. Loaded via the
proven hpmcu.rs SRAM path; do NOT kill warden-flared (dw-wdt). mailbox/VERIFIED.md.
NPU (open GPL rknpu 0.9.2 kernel driver on 6.18):
- DT fix: base npu node lacks interrupt-names, driver requests IRQ byname
'npu_irq' -> probe bailed -ENXIO. Added interrupt-names='npu_irq'.
- Verified: [drm] Initialized rknpu 0.9.2 on minor 1; /dev/dri/card1;
rknpu_version_test PASS (0.9.2 + hw version, full power/clock/reset path).
- Honest ceiling: open compute (regcmd compiler) is a from-scratch ~person-year
RE project, no RV1106 prior art; ship the driver, no blob. npu/VERIFIED.md.
DRIVER-PARITY + CAPABILITIES-AUDIT updated; dts snapshot refreshed.

# RV1106 6.18 driver parity vs the 5.10 vendor kernel
|
||
|
||
Goal: every driver the panel's 5.10 kernel runs must work at ≥ parity on our
|
||
self-built 6.18. Source of truth = the running 5.10 system on warden-c8a3
|
||
(`lsmod` + `/proc/interrupts`, captured 2026-08-24). Verify each on hardware via
|
||
the A/B `_b`-slot loop (`../docs/m2-boot-on-c8a3.md`); ✅ means confirmed on
|
||
c8a3, not just compiled.
