This device has no module-loading infrastructure, so =m configs are silently absent at runtime. Missing SOCK_DIAG made every InetDiagMessage.destroyLiveTcpSockets() call in system_server block ~6s on netlink timeouts (114 times in one 9-minute boot, watchdog-level main-thread stalls, Settings ANRs, stale IP/status UI). Missing AF_VSOCK made traced crash-loop every 5s (vsock://-1:2010 EAFNOSUPPORT), tripping updatable_crashing flag resets. CONFIG_CFG80211_DEFAULT_PS=n: mt7921u with powersave on goes deaf after association - EAPOL 2/4 is sent, msg 3 never heard, AP deauths with reason 15 (4-way handshake timeout) - and idle RTT spikes to 100ms+, delaying inbound connections. Always-powered TV box, so default powersave off is the right trade. Hypervisor-only vsock transports (VMware/virtio) stay off. |

Orange Pi 5 Ultra — Kernel Source
Source kernel for the Orange Pi 5 Ultra (Rockchip RK3588). Forked from
dvab-sarma/android_kernel_rk_opi
(android-16.0-hwaccel-testing branch).
Based on mainline Linux 6.15 with Rockchip DRM patches and Android kernel features (binder, memfd, cgroups, SELinux, etc.).
Device Tree
WiFi (brcmfmac SDIO) and Bluetooth (hci_uart BCM serdev) are enabled in the
rk3588-orangepi-5-compact.dtsi shared DT include. PIN mappings follow
jimmyhon/linux max-wifi branch:
| Function | Pin |
|---|---|
| WIFI_REG_ON | GPIO2 PC5 |
| BT_REG_ON (shutdown) | GPIO4 PC4 |
| BT device wake | GPIO4 PC5 |
| BT host wake | GPIO0 PA0 |
| WiFi host wake | GPIO0 PB0 |
| SDIO | sdiom0_pins |
| BT UART | uart7m0_xfer + ctsn/rtsn |
Building
Built via LineageOS's TARGET_KERNEL_SOURCE mechanism. The kernel is compiled
by AOSP clang during mka:
TARGET_KERNEL_SOURCE := kernel/rockchip/tart
TARGET_KERNEL_CONFIG := tart_defconfig
Output: Image + rk3588-orangepi-5-ultra.dtb at
$(KERNEL_OUT)/arch/arm64/boot/.
Defconfig
tart_defconfig is based on android_orangepi5_defconfig with the same driver
set. Key options:
CONFIG_DRM_PANFROST— Mali-G610 GPU (Panfrost)CONFIG_BRCMFMAC_SDIO— AP6611S WiFiCONFIG_BT_HCIUART_BCM— SYN43711 BluetoothCONFIG_R8169— RTL8125BG 2.5GbE EthernetCONFIG_SND_SOC_ES8388— Audio codec
Branch
lineage-23.2 — for use with LineageOS 23.2 (Android 16).
