+# RadioControl Kernel Modules
+
+Out-of-tree kernel modules for enabling hardware features that are
+compiled out of production Android kernels.
+
+## Build Requirements
+
+- Matching kernel headers for target device
+- ARM64 cross-compiler (aarch64-linux-gnu-gcc)
+- Device-specific kernel config
+
+## Modules
+
+### rc_wifi_mon.ko
+Patches the WiFi driver's nl80211 ops table at runtime to allow
+monitor mode and packet injection on chipsets that have the capability
+but disable it in their cfg80211 change_virtual_intf handler.
+
+Supports:
+- Samsung SCSC/SLSI (slsi_set_monitor_mode — re-enables compiled-out path)
+- Broadcom bcmdhd (patches cfg80211_ops to allow NL80211_IFTYPE_MONITOR)
+- Qualcomm ath11k/ath12k/cnss (typically already supports monitor, but
+  this bypasses vendor restrictions)
+
+### rc_diag_bridge.ko
+Creates /dev/rc_diag — a simplified userspace interface to the Qualcomm
+DIAG subsystem that bypasses the standard diag driver's filtering.
+Allows reading/writing NV items and sending FTM commands from userspace.
+
+### rc_shannon_cmd.ko
+Creates /dev/rc_shannon — direct command interface to Samsung Shannon
+modem bypassing RIL. Allows raw AT command passthrough and IPC message
+injection for band locking, NR mode control, and diagnostic readout.
+
+## Building
+
+```bash
+# Set up cross-compilation
+export ARCH=arm64
+export CROSS_COMPILE=aarch64-linux-gnu-
+export KERNEL_DIR=/path/to/kernel/source
+
+# Build all modules
+make -C $KERNEL_DIR M=$(pwd) modules
+
+# Or build individually
+make -C $KERNEL_DIR M=$(pwd) CONFIG_RC_WIFI_MON=m modules
+```
+
+## Runtime Loading
+
+Modules are loaded by the RadioControl service.sh based on detected chipset.
+KernelSU module overlay places them in /vendor/lib/modules/ or loads
+directly via insmod.
