What: /sys/kernel/config/most_<component>
Date: March 8, 2019
KernelVersion: 5.2
Description: Interface is used to configure and connect device channels
to component drivers.
Attributes are visible only when configfs is mounted. To mount
configfs in /sys/kernel/config directory use:
# mount -t configfs none /sys/kernel/config/
What: /sys/kernel/config/most_cdev/<link>
Date: March 8, 2019
KernelVersion: 5.2
Description:
The attributes:
buffer_size
configure the buffer size for this channel
subbuffer_size
configure the sub-buffer size for this channel
(needed for synchronous and isochrnous data)
num_buffers
configure number of buffers used for this
channel
datatype
configure type of data that will travel over
this channel
direction
configure whether this link will be an input
or output
dbr_size
configure DBR data buffer size (this is used
for MediaLB communication only)
packets_per_xact
configure the number of packets that will be
collected from the network before being
transmitted via USB (this is used for USB
communication only)
device
name of the device the link is to be attached to
channel
name of the channel the link is to be attached to
comp_params
pass parameters needed by some components
create_link
write '1' to this attribute to trigger the
creation of the link. In case of speculative
configuration, the creation is post-poned until
a physical device is being attached to the bus.
destroy_link
write '1' to this attribute to destroy an
active link
