io-sock

Runs on:

QNX Neutrino

Options:

-d driver

Start the specified devs-* driver:

• You can specify driver without the devs- prefix or the .so extension. For example, to start the devs-em.so driver, specify -d em.
• If you want to load a specific version of a driver, specify the full path of the module (e.g., /lib/dll/devs-em.so).

-o opt[,opt...]

The opt variable can be any of the following:

prefix

The path to prepend to the default stack location (/dev/socket). This is useful when you want to run multiple stacks. You can use the SOCK environment variable to specify which stack the client should use. For example, if you specify -o prefix=/alt, set SOCK to /alt.

config

The path to a file that contains tunable values. Specify values in the file using the format value_name="value". The file can contain blank lines and comment lines (starting with #). Do not include extra white space in lines that set values.

timer_pulse_prio

The priority used by the receive thread to handle timer pulses. Default is 21.

taskq_pulse_prio

The priority of the taskqueue and gtaskqueue thread pulses. Default is 21.

isr_pulse_prio

The priority of the pulses sent by the ISRs. Default is 21.

netisr_threads

The number of netisr (kernel network dispatch service) threads to run. Default is 1. -1 specifies the maximum, which is the number of CPUs.

ignore_usb

Don't load the io-usb bus handler.

ignore_pci

Don't load the pci-server handler.

ignore_phy

Don't load the phy-server handler.

usb_stack

Path to the USB stack. Default is set by the USB library.

bootverbose

Enable verbose boot message logging.

dtb

Specify the path to a Device Tree Blob file.

npnp_pci

Disable Plug and Play for PCI devices.

npnp_ofw

Disable Plug and Play for OFW (Open Firmware Bus) devices.

npnp_usb

Disable Plug and Play for USB devices.

iolevel

Specify the level of I/O privilege.

• 0 (_NTO_IO_LEVEL_NONE) — Default on AArch64.
• 1 (_NTO_IO_LEVEL_1) — Default on x86_64.
• 2 (_NTO_IO_LEVEL_2)

foreground

Stop io-sock from becoming a daemon. Valid only with the diagnostic version of io-sock (io-sock-diag). All logs are still sent to slogger2. For more information, see “Running io-sock with diagnostic features.”.
