zephyr,coredump

Description

Pseudo-device to help capturing desired data into core dumps

Properties not inherited from the base binding file.

Name

Details

memory-regions

array

Start address and size of memory regions to be collected in a core dump

coredump-type

string

Designate which type of coredump device this will be.
A device of type COREDUMP_TYPE_MEMCPY can directly memcpy the provided memory-regions
into the coredump. The memory-regions array can contain 0 or more entries, and more
regions can be added at runtime through the coredump_device_register_memory API.
A device of type COREDUMP_TYPE_CALLBACK must specify exactly one entry in the
memory-regions array with a size of 0 and a desired size. The coredump device will statically
allocate a block of memory of the desired size and provide a callback with a pointer to
that memory which will be invoked at the time of a dump. This allows a consumer to add data
into the coredump that may not be directly accessible through a memcpy and/or provides an
opportunity to manipulate data for inclusion in the dump. The coredump_device_register_memory
API is not available for a device of this type.

This property is required.

Legal values: 'COREDUMP_TYPE_MEMCPY', 'COREDUMP_TYPE_CALLBACK'

Base properties

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “zephyr,coredump” compatible.

Name	Type	Details
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
