Hi, i make a separate Thread for Wifi-Integration because main-Thread gets confusing…
wifi-driver in 4.4.70 seems to work well…can anybody help me integrating Wifi-Driver from 4.4.70 to Mainline-Kernel?
i have tried to copy the drivers/misc/mediatek-folder from 4.4.70 to 4.14 and added that in Makefile and Kconfig
i can select the driver in menuconfig, but on build i end up in missing port_ipc.h, which i did not find also in 4.4.70
regards Frank
I can help,I got experience in developing but not kernel,if you will do a quick introduction I will try to help
i’m not a professional programmer, so my attempt is to copy the working driver from 4.4.70 into the sourcetree of 4.14/15 an try to integrate it.
download 4.14:
git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
download source of bpi-r2-repo:
copy the folder “mediatek” to drivers/misc/ of kernel 4.14:
cp -r BPI-R2-bsp/linux-mt/drivers/misc/mediatek linux-stable/drivers/misc/
now add the mediatek-folder to Makefile and Kconfig:
Add line
source "drivers/misc/mediatek/Kconfig"
to linux-stable/drivers/misc/Kconfig before “endmenu” (like it’s done here)
Add line
obj-$(CONFIG_ARCH_MEDIATEK) += mediatek/
to the end of linux-stable/drivers/misc/Makefile like it’s done here
you should be able to start build-process using this commands inside “linux-stable”:
./build.sh importconfig
./build.sh
you came till the point

Hi Frank!
I looked into this and conn_md is module which enables LTE support in MTK devices,so i suggest to disable it.
Just comment line
source “drivers/misc/mediatek/conn_md/Kconfig”
In file
drivers/misc/mediatek/Kconfig
And it builds with success
Link where i found it LINK
Nice next step is to enable the driver to be compiled
CONFIG_MTK_COMBO=y
CONFIG_MTK_COMBO_CHIP_CONSYS_7623=y
CONFIG_MTK_COMBO_COMM=y
CONFIG_MTK_COMBO_WIFI=y
And maybe CONFIG_MTK_BTIF=y and CONFIG_MTK_COMBO_BT=y for Bluetooth
mt7623n_evb_fwu_defconfig (5,2 KB)
now i added the DTS-Sections…
mt7623.dtsi_beforewifi (23,7 KB) mt7623n-bananapi-bpi-r2.dts_beforewifi (9,6 KB) mt7623n-bananapi-bpi-r2.dts_withwifi (10,6 KB) mt7623.dtsi_withwifi (26,6 KB)
dts(i) compiles without errors 
ok, some depencies have now be fixed…
enable_irq i’ve found in “linux/interrupt.h” is needed in drivers/misc/mediatek/connectivity/common/common_detect/mtk_wcn_stub_alps.c
linux/wakelock.h is missing:
linux-stable$ cp …/BPI-R2-bsp/linux-mt/include/linux/wakelock.h include/linux/
now it comes back to conn_md

#include "conn_md_exp.h"
in the moment i add conn_md to makefile (not Kconfig), i got the error for “port_ipc.h”
before the include in wmt_idc.h there is a
if CFG_WMT_LTE_COEX_HANDLING
this seems no constant in menuconfig (did not found it)…must be defined in code…found it here:
drivers/misc/mediatek/connectivity/common/common_detect/wmt_stp_exp.h
#if (WMT_IDC_SUPPORT)
#define CFG_WMT_LTE_COEX_HANDLING 1
#define CFG_WMT_LTE_ENABLE_MSGID_MAPPING 0
#else
#define CFG_WMT_LTE_COEX_HANDLING 0
#endif
drivers/misc/mediatek/connectivity/Makefile
ifeq ($(CONFIG_MTK_CONN_LTE_IDC_SUPPORT),y)
subdir-ccflags-y += -D WMT_IDC_SUPPORT=1
else
subdir-ccflags-y += -D WMT_IDC_SUPPORT=0
endif
CONFIG_MTK_CONN_LTE_IDC_SUPPORT is now the kernel-option, which is set by default:
drivers/misc/mediatek/connectivity/Kconfig:
config MTK_CONN_LTE_IDC_SUPPORT
bool "MediaTek CONN LTE IDC support"
select MTK_CONN_MD
default y <<<<<<<<<<<<<<<<<
help
This option enables CONN LTE IDC support
current codebase inside (without change in osal.h) drivers/misc/mediatek: https://drive.google.com/file/d/1jiecrynd2SjSI6kVK-fFyIp0x1269fYG/view?usp=sharing
now that:
cat: drivers/misc/mediatek/connectivity/common/conn_soc//modules.order: inputfile is outputfile
looked in drivers/misc/mediatek/connectivity/common/conn_soc/Makefile, but there is nothing be done with modules.order…where does this cat-command come from?? i see that between “conn_soc” and “modules.order” are 2 “/” so it seems that there is a undefined variable in the path
the cat seems to a generic command (maybe from main Makefile), but how to find the problematic line in code?
all changes in one patch (thanks to gary for most of that,added/changed my stuff): https://drive.google.com/file/d/1lLU8HxVOppntQVCtmG8PSpZq4jhAG1dP/view?usp=sharing
ok, fixed the modules.order-problem…
drivers/misc/mediatek/connectivity/common/conn_soc/Makefile:
- obj-y += $(subst ",,$(CONFIG_MTK_PLATFORM))/
+ obj-y += mt7623/
or set (maybe this should be done automaticly when selecting MTK_COMBO_CHIP_CONSYS_7623 in drivers/misc/_mediatek/connectivity/Kconfig)
CONFIG_MTK_PLATFORM="mt7623"
now build-progress continues…
changing “if CONFIG_NL80211_TESTMODE” to “ifdef CONFIG_NL80211_TESTMODE” in these 3 files:
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/include/gl_p2p_os.h
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/include/gl_os.h
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/include/gl_p2p_ioctl.h
edit: added these to patch on google-drive till this point…
then you get the #error for that you need to set CONFIG_NL80211_TESTMODE in kernel-config
now the errors come that i’ expecting (compatibility issues from wireless-libs):

First one i have no idea to fix…adding the member to the struct seems not the right way,or am i wrong? The other errors should be easy.
Hi Frank
Just for you reference, we’ve merged the driver of MT6625 to lede project(Kernel 4.9.44), looks like both STA and AP are working, you can get the patch from below link:
Commits:
thank you, cloning new 14.4 and patching with the new…
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/gl_kal.c add “#include <linux/sched/debug.h>” (show_stack)
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/gl_kal.c:4427 added 0-param for reqid:
cfg80211_sched_scan_results(priv_to_wiphy(prGlueInfo),0);
added “cfg80211_roamed_bss” to include/net/cfg80211.h

these 2 function use “aucProcBuf” as target…which is defined in same file as

i’m not sure, but assume, that the problem is u4CopySize instead of the param “size_t count”
What does kalmemset exactly do?
drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/include/gl_kal.h:
/* Set memory block with specific pattern */
#define kalMemSet(pvAddr, ucPattern, u4Size) memset(pvAddr, ucPattern, u4Size)
so it does not resize the mem, only change content…
The order of commands is strange (first memset,then adjust size,then copy),maybe kalmemset makes the targetbuffer aucProcBuf too small if count is larger than sizeof(aucProcBuf)…tried to move kalmemset after change of u4CopySize, but no success
Maybe i can show actual and needed values somehow…but i don’t know
currently fixed it by changing initialization of u4CopySize in both functions:
UINT_32 u4CopySize = kalStrLen(aucProcBuf);//sizeof(aucProcBuf);

i assume that there is an include missing in any makefile, but how to solve this??
e.g.
frank@Frank-Laptop:/media/data_ext/test_4.14/linux-stable2$ grep -Rn 'mtk_wcn_btif_dbg_ctrl'
drivers/misc/mediatek/btif/common/inc/mtk_btif_exp.h:244:int mtk_wcn_btif_dbg_ctrl(unsigned long u_id, ENUM_BTIF_DBG_ID flag);

drivers/misc/mediatek/btif/common/mtk_btif_exp.c:491:EXPORT_SYMBOL(mtk_wcn_btif_dbg_ctrl);
Binary file drivers/misc/mediatek/connectivity/common/conn_soc/linux/pri/stp_btif.o matches
drivers/misc/mediatek/connectivity/common/conn_soc/linux/pri/stp_btif.c:259: iRet = mtk_wcn_btif_dbg_ctrl(stpBtifId, flag);
frank@Frank-Laptop:/media/data_ext/test_4.14/linux-stable2$ nano drivers/misc/mediatek/connectivity/common/conn_soc/linux/pri/Makefile
function mtk_wcn_btif_dbg_ctrl is defined in drivers/misc/mediatek/btif/common/inc/mtk_btif_exp.h so i have to include it to drivers/misc/mediatek/connectivity/common/conn_soc/linux/pri/Makefile, right? but there is already a line including that dir
ccflags-y += \
-I$(src)/../../linux/include \
-I$(src)/../../linux/pri/include \
-I$(src)/../../core/include \

as you see the EXPORT_SYMBOL is done in c-file…tried to move to header, but without success any idea?
as for cfg80211_roamed_bss, function is defined in cfg80211.h, but seems not be implemented anywhere…only called in drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/gl_kal.c, same in kernel 4.4.70…maybe cfg80211_roamed must be used like here: https://www.spinics.net/lists/linux-wireless/msg161781.html
struct cfg80211_roam_info {
struct ieee80211_channel *channel;
struct cfg80211_bss *bss;
const u8 *bssid;
const u8 *req_ie;
size_t req_ie_len;
const u8 *resp_ie;
size_t resp_ie_len;
bool authorized;
};
void cfg80211_roamed(struct net_device *dev, struct cfg80211_roam_info *info,
gfp_t gfp);
instead of
void cfg80211_roamed_bss(struct net_device *dev, struct cfg80211_bss *bss,
const u8 *req_ie, size_t req_ie_len,
const u8 *resp_ie, size_t resp_ie_len, gfp_t gfp);
so i fixed the cfg80211_roamed_bss-error:
if (eStatus == WLAN_STATUS_ROAM_OUT_FIND_BEST) {
/*cfg80211_roamed_bss(prGlueInfo->prDevHandler,
bss,
prGlueInfo->aucReqIe,
prGlueInfo->u4ReqIeLength,
prGlueInfo->aucRspIe, prGlueInfo->u4RspIeLength, GFP_KERNEL);
*/
struct cfg80211_roam_info roam_info = {
.bss = bss,
.req_ie = prGlueInfo->aucReqIe,
.req_ie_len = prGlueInfo->u4ReqIeLength,
.resp_ie = prGlueInfo->aucRspIe,
.resp_ie_len = prGlueInfo->u4RspIeLength
};
cfg80211_roamed(prGlueInfo->prDevHandler,
&roam_info,
GFP_KERNEL);
} else {
but the mtk_* functions are defined in drivers/misc/mediatek/btif/common/mtk_btif_exp.c and in makefile there is also a mtk_btif_exp.o 
any idea with the others?
the genetlink (must be reworked if all works, maybe the __functions are not needed) was also easy…simply change the call
static inline int
_genl_register_family_with_ops_grps(struct genl_family *family,
const struct genl_ops *ops, size_t n_ops,
const struct genl_multicast_group *mcgrps,
size_t n_mcgrps)
{
family->module = THIS_MODULE;
family->ops = ops;
family->n_ops = n_ops;
family->mcgrps = mcgrps;
family->n_mcgrps = n_mcgrps;
return genl_register_family(family); //instead of __genl_register_family
}
anybody has an idea with the mtk_-functions??? here i have no clue, what’s the problem on linking
updated patch: https://drive.google.com/file/d/1yZSnLjRF6XP-asVR-YsIJdqRg-2C8_C1/view?usp=sharing
currently i have not enabled CONFIG_MTK_BTIF=y and CONFIG_MTK_COMBO_BT=y, assume thats the problem (no btif.o exists)…if i enable it i got

First know I appreciate the work you do. Just as a suggestion, you could create a public fork of the kernel on github and commit the (not yet building) code there. Then it’s much easier for us to review the commits you do, help you with it, build it ourselves, do our own patches or provide you with pull requests and in the end merge it somewhere. You could also point to specific parts by linking to github. I’m really not trying to force you in a certain way of working, feel free to continue as you like 
.
Hi
I’m not a pro in using git 
Have not done a fork before and don’t know how to held the kernel itself up-to-date (4.14.5 is recently released). So a complete patch seems to be the easiest way. Also have not done pull request and all the other maintaining.
If you give me a step-by-step guide how to do it i will try it
Forked it: https://github.com/frank-w/linux
How to set base to 4.14.y? Have only tag 4.14
How can i include the path there?
+1 was trying to keep up,but most time take me just setting up repo and applying patches.
Great! Looking good! Now you can create a branch from tag 4.14 online with github, call it as you like. Then git clone the repository to your development machine and change the branch with git checkout. Overwrite and git add the files with updated code (try to be conservative with changes as possible, to keep things readable, you can check with git diff --cached). When you finished git commit the code to your local ‘clone’ and then git push the code back to github. You should be able to view the result online.
You could use tools like SourceTree or TortoiseGit to support you in getting familiar with git. Another way is do the interactive tutorial at https://try.github.io/. It probably takes a few times back to google, but it will pay off eventually.
renamed repository:
edit: updated wifi-branch (fixed dts, config and add logging to build.sh…)
anyone tried to build? you have not make it compile complete…step by step
IMHO first we must separate wifi from BT in the common-dir (common/conn_soc/linux/pri) to get first wifi running without BT
I just successfully built the main branch (as a test), but didn’t try to run it yet. To be honest the build.sh isn’t really convenient for me because I have different paths, compiler settings, make flags and git usage. But it can be useful as a reference.
Later I will switch to the wifi branch and check out how I can contribute.
build.sh is only a start to get a working kernel
of course you can use your own script/environment…i want to make a small script to do the common tasks in building
tried to set function-calls to btif-functions in
#ifdef CONFIG_MTK_BTIF
...
#endif
to get rid of the depencies, till i come to drivers/misc/mediatek/connectivity/common/conn_soc/core/wmt_ctrl.c
/*do not need contol uart because B/G/F send/receive data by BTIF*/
B/G/F are the wifi-bands, right? seems that BTIF does not stand for BlueToothInterFace…whats the meaning?

MediaTek BTIF controller is the serial interface similar to UART but it works only as the digital device which is mainly used to communicate with the connectivity module also called CONNSYS inside the SoC which could be mostly found on those MediaTek SoCs with Bluetooth feature.
BTIF is needed for wifi and bt see Gary’s answer: 2.4Ghz and 5.6Ghz Wifi Working fine
as of the other errors, i’ve found out that in 4.4.70 there is
include/linux/device.h:303:#define DRIVER_ATTR(_name, _mode, _show, _store)
in 4.14 this is missing…
seems to be related: https://patchwork.kernel.org/patch/9851919/
then we must use one of these:
#define DRIVER_ATTR_RW(_name) \
struct driver_attribute driver_attr_##_name = __ATTR_RW(_name)
#define DRIVER_ATTR_RO(_name) \
struct driver_attribute driver_attr_##_name = __ATTR_RO(_name)
#define DRIVER_ATTR_WO(_name) \
struct driver_attribute driver_attr_##_name = __ATTR_WO(_name)
but here the functions seems not to be given as params…how to set _show and _store? the macro builds the function-name together…see actual commit compiles fine
but throws a kernel-panic when wmt_launcher is running:

Is there any debug-mode to see on which step it failes? There are messages with WMT_INFO_FUNC and WMT_ERR_FUNC…how to display them?
try to add some printk’s like it’s recommended here: https://elinux.org/Debugging_by_printing (Author’s practical advice)
oh, is see the messages only in dmesg

wmt_dev.c (68,8 KB) wmt_plat_alps.c (44,9 KB)
seems that the problem is that my cfg could not be loaded…have lowercase filename instead of uppercase (for whatever reason) after renaming, kernel hangs…seems that kernel has crashed more than i thought…the renaming was not present after a reset…so i renamed again and started wmt_loader:

pushed current state to my github-wifi-branch
https://github.com/frank-w/BPI-R2-4.14/tree/wifi_mt6625l
and uploaded compiled Kernel to my gdrive
https://drive.google.com/drive/folders/1EGN1TvqCpDHdOAS-mjRg9ipi0kahnOUV
happy testing
some messages in log that should be fixed, if all is working and debug-kprints are removed: wifi_dmesg.log (6,5 KB)
