Ported the vendor multicore RGA char-dev driver (drivers/video/rockchip/rga3/, CONFIG_ROCKCHIP_MULTI_RGA) to 6.18 — WardenOS's librga uses /dev/rga, not V4L2. On warden-c8a3: rga2 probe successful, hw_version 3.3.87975, /dev/rga + /dev/dma_heap present. This is the CPU-savings 2D accelerator (LVGL UI offload). 6 mechanical 5.10->6.18 API fixes (platform remove->void, hrtimer_init-> hrtimer_setup, iommu_map* gfp arg, get_user_pages_remote vmas arg, MAX_ORDER compat, MODULE_IMPORT_NS string). CMA via the default 64 MiB pool + DMABUF_HEAPS_CMA (a custom linux,cma DT node hangs boot). Recipe + deltas in rga/PORT-DONE.md. All open source (vendor C source).

# 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.
