Hello,


I started playing  tweaking usbdevs file in the Intel Nuc 8i7BEH
NetBSD-10_RC3 amd64- I added the line:

product REALTEK RTL8188FTV      0xf179  RTL8188FTV

 then tried  adding a line in  if_urtwn.c file just to see what happened:


#define URTWN_DEV(v,p)  { { USB_VENDOR_##v, USB_PRODUCT_##v##_##p }, 0 }
#define URTWN_RTL8188E_DEV(v,p) \
        { { USB_VENDOR_##v, USB_PRODUCT_##v##_##p }, FLAG_RTL8188E }
#define URTWN_RTL8192EU_DEV(v,p) \
        { { USB_VENDOR_##v, USB_PRODUCT_##v##_##p }, FLAG_RTL8192E }
static const struct urtwn_dev {
        struct usb_devno        dev;
        uint32_t                flags;
#define FLAG_RTL8188E   __BIT(0)
#define FLAG_RTL8192E   __BIT(1)
} urtwn_devs[] = {
        URTWN_DEV(ABOCOM,       RTL8188CU_1),
...
...
        URTWN_DEV(REALTEK,      RTL8188FTV),
...
...
};
#undef URTWN_DEV
#undef URTWN_RTL8188E_DEV
#undef URTWN_RTL8192EU_DEV
...
...


Started kernel compilation and ended with error:

soon realized that usbdevs.h file was not automatically updated as I
thought and I did not found the #define line of the chip I added in
usbdevs file.

Reading usbdevs.h said that make -f Makefile.usbdevs should be executed:

netbsd-nuc# cd /usr/src/sys/dev/usb
netbsd-nuc# make -f Makefile.usbdevs
/bin/rm -f usbdevs.h usbdevs_data.h
/usr/src/tooldir.NetBSD-10.0_RC3-amd64/bin/nbawk -f
/usr/src/sys/dev/usb/../devlist2h.awk usbdevs
make: exec(/usr/src/tooldir.NetBSD-10.0_RC3-amd64/bin/nbawk) failed
(No such file or directory)
*** Error code 1

Stop.
make: stopped in /usr/src/sys/dev/usb
netbsd-nuc#

I am stuck now. Perhaps should I build everything, userland and
kernel? I think I am missing many things  :-(

Thanks.
Ramiro.
