Dependencies

8. sound.ko

• FreeBSD PCM audio device infrastructure

• The sound drivers may create the following device nodes:

• 1. /dev/dsp%d: Audio device. The number represents the unit number of the device.

• 2. /dev/dsp: Alias of /dev/dsp${hw.snd.default_unit}. Available only if hw.snd.basename_clone is set.

• 3. /dev/sndstat: Current sound status, including all channels and drivers

• sndstat : nvlist-based PCM audio device enumeration interface. The ioctl interface provided by /dev/sndstat device allows callers to enumerate PCM audio devices available for use.

Use case

1. Check if your FreeBSD laptop has an Intel Bluetooth chipset

test:~$ usbconfig
ugen0.1: <Intel XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.2: <Chicony HP Wide Vision HD Camera> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
ugen0.3: <Wireless-AC 3168 Bluetooth Intel Corp.> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)
ugen0.4: <ELAN Touchscreen> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

• From above output we know ‘Wireless-AC 3168 Bluetooth Intel Corp’ chip and ‘Intel XHCI root HUB’ is used

2. Install the Intel BT firmware binary, iwmbt-firmware

test:~$ pkg install iwmbt-firmware

3. After installing the firmware, reboot or restart ‘devd’ to enable it

test:~$ service devd restart

4. Install Virtual OSS which is required for Bluetooth audio to work on FreeBSD

test:~$ pkg install virtual_oss

5. Virtual OSS requires the user space character device driver (CUSE) to be loaded.

• Load it manually and enable loading for every boot

test:~$ kldload cuse

test:~$ sysrc kld_list+="cuse"

6. Start Bluetooth Stack

test:~$ service hcsecd onestart

• If this fails, do it again

test:~$ service bluetooth start ubt0

• If Bluetooth is started successfully, below logs should be seen in dmesg

test:~$ dmesg | grep ubt0
ubt0 on uhub0
ubt0: <vendor 0x8087 product 0x0aa7, class 224/1, rev 2.00/0.01, addr 3> on usbus0

• Output of ngctl

test:~$ ngctl list

7. Find your Bluetooth headphones (put your headphones in pairing mode)

test:~$ hccontrol -n ubt0hci inquiry
Inquiry result, num_responses=1
Inquiry result #0
        BD_ADDR: f8:9e:94:ee:99:c3
        Page Scan Rep. Mode: 0x1
        Page Scan Period Mode: 00
        Page Scan Mode: 00
        Class: 2a:01:0c
        Clock offset: 0x333b
Inquiry complete. Status: No error [00]

8. Find out the name assigned to Bluetooth device to check if the scanned device is Bluetooth headphone

test:~$ hccontrol -n ubt0hci remote_name_request f8:9e:94:ee:99:c3
BD_ADDR: f8:9e:94:ee:99:c3
Name: OnePlus Buds

9. Edit ‘/etc/bluetooth/hcsecd.conf’ and add your Bluetooth device

• Headphones does not require a key or pin so I add nokey and 0000 as the pin

test:~$ vim /etc/bluetooth/hcsecd.conf

device {
    bdaddr  f8:9e:94:ee:99:c3;
    name    "OnePlus Buds";
    key     nokey;
    pin     "0000";
}

10. Edit ‘/etc/bluetooth/hosts’ to assign an alias to your Bluetooth device

• This step is optional, ‘/etc/bluetooth/hosts’ allows you to alias BD_ADDR addresses to names making it much easier to remember

test:~$ vim /etc/bluetooth/hosts

f8:9e:94:ee:99:c3 headphones

11. Create connection to your Bluetooth headphones (Make sure headphones are in pairing mode)

test:~$ hccontrol -n ubt0hci create_connection headphones

• Note:  Enable “write_authentication” on the HCI node, if you observe below error

• Error message:

test:~$ hccontrol -n ubt0hci create_connection headphones
BD_ADDR: headphones
Connection handle: 256
Encryption mode: Disabled [0]

• Resolution:

test:~$ hccontrol -n ubt0hci write_authentication_enable 1

test:~$ hccontrol -n ubt0hci create_connection headphones

12. Check if headphones are connected

test:~$ hccontrol -n ubt0hci read_connection_list
Remote BD_ADDR    Handle Type Mode Role Encrypt Pending Queue State
headphones           256  ACL    0 MAST    NONE       0     0 OPEN

13. Create a virtual sound device so you can use your bluetooth headphones as a sound sink

• Meaning of the below command:

• To expose virtual device to other apps, install entry in /dev/sndstat. (-T /dev/sndstat)

• Enabled automatic resampling to fix bad sound quality when playing audio with a different sample-rate than default. (-S)

• If the default volume is too high, set a negative output amplification. (-a o,-4)

• Sample rate of 44100 Hz is chosen, you can use 48000 Hz instead if that’s better for your hardware. (-r 44100)

• To use laptop’s internal mic simultaneously while using my headphones. ( -R /dev/dsp0). You can disable the recording device by setting “-R /dev/null” instead.

test:~$ virtual_oss -T /dev/sndstat -S -a o,-4 -C 2 -c 2 -r 44100 -b 16 -s 1024 -R /dev/dsp0 -P /dev/bluetooth/headphones -d dsp -t vdsp.ctl

• Now we should have another DSP device listed in /dev/sndstat

test:~$ cat /dev/sndstat
Installed devices:
pcm0: <Realtek ALC257 (Analog 2.0+HP/2.0)> (play/rec) default
pcm1: <Realtek ALC257 (Right Analog Mic)> (rec)
pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> (play)
Installed devices from userspace:
dsp: <Virtual OSS> (play/rec)

• Above steps works great for programs that use OSS as sound backend. However, other backends need additional steps

14. To fix applications that use sndio as backend (e.g. Chromium), enable the sndiod service

test:~$  sysrc sndiod_enable=YES

test:~$ service sndiod start

15. To fix applications that use a pulseaudio as backend (e.g. Firefox and linux Brave)

• Method-1: Configure firefox to use OSS instead of pulseaudio

• Open up firefox and put about:config in the URL line

• Then add the following entry

• media.cubeb.backend: oss

• Method-2: Redirect all OSS output into pulseaudio. It adds latency to the audio but works

test:~$ pacat --record -d oss_output.dsp0.monitor

Device structure

• Abstract representation of a device

• Defined in /usr/src/stand/kshim/bsd_kernel.h

typedef struct device *device_t;

struct device {
        TAILQ_HEAD(device_list, device) dev_children;
        TAILQ_ENTRY(device) dev_link;

        struct device *dev_parent;
        const struct module_data *dev_module;
        void   *dev_sc;
        void   *dev_aux;
        driver_filter_t *dev_irq_filter;
        driver_intr_t *dev_irq_fn;
        void   *dev_irq_arg;

        uint16_t dev_unit;

        char    dev_nameunit[64];
        char    dev_desc[64];

        uint8_t dev_res_alloc:1;
        uint8_t dev_quiet:1;
        uint8_t dev_softc_set:1;
        uint8_t dev_softc_alloc:1;
        uint8_t dev_attached:1;
        uint8_t dev_fixed_class:1;
        uint8_t dev_unit_manual:1;
};

• The device object represents a piece of hardware attached to the system.

• Ex: expansion card, the bus which that card is plugged into, disk drives attached to the expansion card, …

• The system defines one device, - root_bus.

• All other devices are created dynamically during auto configuration.

• device_probe_and_attach()

  • initialise a device

  • This function is called during autoconfiguration to initialise the devices in the system.

  • For each device, the DEVICE_PROBE method of each suitable driver is called and if a probe succeeds, a description of the device is printed and the DEVICE_ATTACH method is called

• DEVICE_PROBE

  • probe for device existence

  • method should probe to see if the device is present.

• DEVICE_ATTACH

  • attach a device

  • Attach a device to the system after the DEVICE_PROBE() method has been called and has indicated that the device exists

Driver structure

• structure describing a device driver

• Defined in /usr/src/stand/kshim/bsd_kernel.h

typedef struct driver driver_t;

struct driver {
        const char * name;
        const struct device_method *methods;
        uint32_t size;
};

• Driver is registered with the system by the DRIVER_MODULE macro

• Each driver will implement one or more sets of methods called interfaces.

• Ex: methods from Device interface, methods from Bus interface

Communication

• ng_ubt(BT driver/host controller) –> usb.ko(USB client driver) –> xhci.ko(USB host controller) –> pci(client driver) –> pci host controller
