Hi,

We are trying to port WIFI Display Miracast support into NXP AOSP using Marvell chip WIFI W8997-M1216 (NXP's AOSP 9-1.0.0/10-1.0.0). Below the steps that we have done to try port Miracast support into NXP AOSP.
1) Test using:
  • CPU: imx8mq/imx8qm/imx8qxp
  • OS: Android 9-1.0.0 / 10-1.0.0
  • WI-FI  chip: Marvell sd8997
  • Miracast Dongle: Miracast Microsoft dongle
  • Chromecast

 

I'm able to patch the android Framework to scan the Miracast WI-FI Display (P2P) device using Android UI "Cast" button. 
To do that we apply the following patch:
 
-----------------------------------------------------------------------------------------------------------------------------------------------
Under sd8997 Driver we add the following config to support wifi-display and wifidirect:
 
android9/vendor/nxp-opensource/kernel_imx/arch/arm64/configs/seco_c20_android_defconfig
# WIDI/WI-FI Display support
CONFIG_SD8997_WIFI_DIRECT_SUPPORT=y
CONFIG_SD8997_WIFI_DISPLAY_SUPPORT=y
CONFIG_SD8997_UAP_SUPPORT=y
CONFIG_SD8997_STA_SUPPORT=y
 
 
android9/vendor/nxp-opensource/kernel_imx/arch/arm64/boot/dts/seco/seco-imx8mq-c20.dtsi:
sd8xxx-wlan {
         //drvdbg  = <0x37>;
         drv_mode = <0x7>;
         cfg80211_wext = <0xf>;
         sta_name = "wlan";
         wfd_name = "p2p";
         max_vir_bss = <1>;
         cal_data_cfg = "mrvl/cal_data.conf";
         fw_name = "mrvl/sdsd8997_combo_v4.bin";
         reg_alpha2 = "US";
         p2p_enh = <1>;
         auto_ds=<0>;
         inact_tmo = <3000>;
         gtk_rekey_offload = <1>;
         cfg80211_drcs = <0>;
    };
 
-----------------------------------------------------------------------------------------------------------------------------------------------
We patch also the wpa_supplicant:
external/wpa_supplicant_8/wpa_supplicant/android.config
# Wi-Display Support
CONFIG_DRIVER_NL80211=y
CONFIG_CTRL_IFACE=y
CONFIG_P2P=y
CONFIG_AP=y
CONFIG_WPS=y
CONFIG_WPS2=y
CONFIG_WIFI_DISPLAY=y
 
-----------------------------------------------------------------------------------------------------------------------------------------------
We do some test on Linux Android side:
For debugging purpose we try to enstablish p2p connection to the Miracast Dongle using wpa_cli command line, using the following steps:
We add support for p2p0 interface in wpa_supplicant system service:
service wpa_supplicant /vendor/bin/hw/wpa_supplicant \
    -ip2p0 -dd -Dnl80211 -c/data/vendor/wifi/wpa/p2p_supplicant.conf \
    -puse_multi_chan_concurrent=1 \
    -N -iwlan0 -Dnl80211 -c/data/vendor/wifi/wpa/wpa_supplicant.conf \
    -puse_multi_chan_concurrent=1 \
    -N -iuap0 -Dnl80211 -c/data/vendor/wifi/wpa/wpa_supplicant.conf \
    -puse_multi_chan_concurrent=1 \
    -C /data/vendor/wifi/wpa/sockets \
    -e/data/misc/wifi/entropy.bin -g@android:wpa_wlan0
    interface android.hardware.wifi.supplicant@1.0::ISupplicant default
    interface android.hardware.wifi.supplicant@1.1::ISupplicant default
    class main
    socket wpa_wlan0 dgram 660 wifi wifi
    disabled
    oneshot
The following p2p_supplicant.conf has been used:
disable_scan_offload=1
p2p_go_vht=1
p2p_no_group_iface=1
Then from Terminal, we use the following commands:
$ wpa_cli -i p2p0
>p2p_find
>p2p_stop_find
We check wich devices respond to the p2p broadcast using:
> p2p_peers
c6:9d:ed:f5:9b:d5
ce:d4:2e:0d:7e:a0
Then we try to connect to c6:9d:ed:f5:9b:d5 (Miracast dongle) using:

I think the problem is due to this last 2 lines. The 2 devices don't establish the p2p connection though we sent and intent of 15 to begin the GO in the p2p connection.

We also work on Android Framework, in particular: we enable wifi-display scan apply the following patch:
 
android9/frameworks/base/services/core/java/com/android/server/display/DisplayManagerService.java
private void registerWifiDisplayAdapterLocked() {
-        if (mContext.getResources().getBoolean(
-                com.android.internal.R.bool.config_enableWifiDisplay)
-                || SystemProperties.getInt(FORCE_WIFI_DISPLAY_ENABLE, -1) == 1) {
+    
             mWifiDisplayAdapter = new WifiDisplayAdapter(
                     mSyncRoot, mContext, mHandler, mDisplayAdapterListener,
                     mPersistentDataStore);
             registerDisplayAdapterLocked(mWifiDisplayAdapter);
-        }
     }
 
     private boolean shouldRegisterNonEssentialDisplayAdaptersLocked() {
-----------------------------------------------------------------------------------------------------------------------------------------------
We try also to apply this patch for Android 9:
 
----------------------------------------------------------------------------------------------------------------------------------------------
When we try to enstablish P2P Connection with Miracast Dongle using:
 
"Cast Button"->Settings->MSDisplayAdapter_D5 (our Miracast Dongle name)
 
We receive the following output from terminal (driver side):

We need also a guide to completely support sd8997 Marvell wifi driver and Android HAL library to bring up WIFI-DISPLAY support. We need something like that to completely support W8997-M1216 (sd8997) and related sources HAL libraries and drivers. 
The guide:
means the presence of the files listed below:
pastedImage_5.png
 
Can you give us some tips to support Miracast source and sync from our imx8 board? I have attached to this link some screen of our test during the p2p pair phase.
The test is done trying to pair:
1) MSDisplayAdapter_D5 (dongle Miracast)
2) [LG] webOS TV SM8200PLA (TV)
3) Xiaomi Mi A1 (Android Phone)
Using imx8qxp Android 10-1.0.0, imx8mq Android 9-1.0.0 (As Miracast Source)
Let me know if you need more information about that.
Thanks in advance.

Hello Tommaso,

Are you fixed to use 8997 or the imx8mq board or Android P for your development?

If you check the latest android 10 AOSP package from NXP, it has the driver for 8997 and Wi-Fi/BT HAL integrated into it.

It would be a good data point to check it out.

Next step would be get the P2P working first. Last time when I checked, Wi-Fi display was not working. But P2P connections would always go through with 8887, 8801 and 8987 modules that u-blox offers.

Thanks

Achyut

Hi Gusarambula,

At the moment we are able to enstablish connection with LG smart TV patching AOSP wpa_supplicant. We are stuck on encoder issue.

 

Let me explain:

First we try to bring-up Miracast support on imx8mq, only for test. Imx8mq is not the final solution but at the moment is the only board that have sd8997 wifi chip. Using this setup and patching NXP AOSP wpa_supplicant we establish p2p connection with LG Smartv.

After that we stop the test, because we read on NXP documentation about imx8mq vpu don't support encoding.

 

We start then to test imx8qm. First of all we test imx8qm vpu encoding using "screenrecord" command line tool. It seems does not work. Before continuing we have to solve encoding. Below you can find our log.

Hello Tommaso, 

I was asking internally and wireless chipsets usually provide L2 level Wi-Fi Direct connection over p2p0 interface and each customer manages the upper level Miracast stack.

For P2P operation (and considering this is Android), uBlox has a 8997 driver/firmware release and the Vendor HAL code needed to bring up wireless chipset on Android.

Are you able to successfully enable Wi-Fi Direct connection using p2p0 interface?

Regards,
