From 87f825e6e246cee0cdeaafd5bba4ef8c6df2748d Mon Sep 17 00:00:00 2001 From: Eyal Ilsar Date: Tue, 22 May 2018 22:02:56 +0300 Subject: wcn36xx: Add support for Factory Test Mode (FTM) Introduce infrastructure for supporting Factory Test Mode (FTM) of the wireless LAN subsystem. In order for the user space to access the firmware in test mode the relevant netlink channel needs to be exposed from the kernel driver. The above is achieved as follows: 1) Register wcn36xx driver to testmode callback from netlink 2) Add testmode callback implementation to handle incoming FTM commands 3) Add FTM command packet structure 4) Add handling for GET_BUILD_RELEASE_NUMBER (msgid=0x32A2) 5) Add generic handling for all PTT_MSG packets Signed-off-by: Eyal Ilsar Signed-off-by: Ramon Fried Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/wcn36xx/testmode_i.h | 29 +++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 drivers/net/wireless/ath/wcn36xx/testmode_i.h (limited to 'drivers/net/wireless/ath/wcn36xx/testmode_i.h') diff --git a/drivers/net/wireless/ath/wcn36xx/testmode_i.h b/drivers/net/wireless/ath/wcn36xx/testmode_i.h new file mode 100644 index 000000000000..8a1477ffd5a0 --- /dev/null +++ b/drivers/net/wireless/ath/wcn36xx/testmode_i.h @@ -0,0 +1,29 @@ +/* + * Copyright (c) 2018, The Linux Foundation.
