Bug#911831: linux: Serial port of dw-abp-uart missing due to serial dev bus activation
Source: linux
Version: 4.18.10-2
Severity: normal
Dear Maintainer,
Since the upgrade of our system from Debian 9 (Stretch) to 10 (Buster), but
also from Ubuntu 16.04 LTS (Xenial) to 18.04 LTS (Bionic), the serial port
of our Atom E3950-based board can no longer be used.
I have traced the cause to the enabling of CONFIG_SERIAL_DEV_BUS=y and
CONFIG_SERIAL_DEV_CTRL_TTYPORT=y in the kernel config of versions
4.17.0-3 (Debian) and 4.15.0.36.38 (Ubuntu).
In a working system the dw-abp-uart driver exposes two tty devices:
# dmesg | grep tty
[ 2.437836] dw-apb-uart.2: ttyS0 at MMIO 0x8121c000 (irq = 4, base_baud = 115200) is a 16550A
[ 2.439193] dw-apb-uart.3: ttyS1 at MMIO 0x8121a000 (irq = 6, base_baud = 115200) is a 16550A
of which we always use ttyS1. (I do not know why ttyS0 does nothing,
supposedly this system has only one UART?) The corresponding udev info is:
looking at device '/devices/pci0000:00/0000:00:18.0/dw-apb-uart.2/tty/ttyS0':

However, when the serial device bus with the serial TTY control port is
enabled, ttyS1 disappears:
# dmesg | grep tty
[ 2.499748] dw-apb-uart.2: ttyS0 at MMIO 0x8121c000 (irq = 4, base_baud = 115200) is a 16550A
[ 2.500852] dw-apb-uart.3: ttyS1 at MMIO 0x8121a000 (irq = 6, base_baud = 115200) is a 16550A
[ 2.500996] serial serial0: tty port ttyS1 registered
The difference in the udev info is:
looking at device '/devices/pci0000:00/0000:00:18.2/dw-apb-uart.3/serial0/serial0-0':
KERNEL=="serial0-0"
SUBSYSTEM=="serial"
DRIVER==""
looking at parent device '/devices/pci0000:00/0000:00:18.2/dw-apb-uart.3/serial0':
KERNELS=="serial0"
SUBSYSTEMS=="serial"
DRIVERS==""
and there is no longer tty under /sys/devices/pci0000:00/0000:00:18.2/dw-apb-uart.3.
Attached is the full dmesg output for the broken tty port instance. Let me know
if more information is required.
I must also note that I am not very knowledgeable about the serial
interface internals, so feel free to point me to any further reading to
understand what is going on under the hood.
Kind regards,
Paul van Tilburg
