Function Documentation

float switchtec_die_temp

(

struct switchtec_dev *

dev

)

Get the die temperature of the switchtec device.

Parameters

[in]

dev

Switchtec device handle

Returns

The die temperature (in degrees celsius) or a negative value on failure

Definition at line 846 of file switchtec.c.

int switchtec_echo	(	struct switchtec_dev *	dev,
		uint32_t	input,
		uint32_t *	output
	)

Perform an MRPC echo command.

Parameters

[in]	dev	Switchtec device handle
[in]	input	The input data for the echo command
[out]	output	The result of the echo command

Returns

0 on success, error code on failure

The echo command takes 4 bytes and returns the bitwise-not of those bytes.

Definition at line 623 of file switchtec.c.

int switchtec_get_device_info	(	struct switchtec_dev *	dev,
		enum switchtec_boot_phase *	phase,
		enum switchtec_gen *	gen,
		enum switchtec_rev *	rev
	)

Get device generation, revision, and boot phase info.

Parameters

[in]	dev	Switchtec device handle
[out]	phase	The current boot phase
[out]	gen	Device generation
[out]	rev	Device revision

Returns

0 on success, error code on failure

Definition at line 796 of file switchtec.c.

int switchtec_hard_reset

(

struct switchtec_dev *

dev

)

Perform an MRPC hard reset command.

Parameters

[in]

dev

Switchtec device handle

Returns

0 on success, error code on failure

Note: if your system does not support hotplug this may leave the Switchtec device in an unusable state. A reboot would be required to fix this.

Definition at line 639 of file switchtec.c.

int switchtec_log_to_file	(	struct switchtec_dev *	dev,
		enum switchtec_log_type	type,
		int	fd
	)

Dump the Switchtec log data to a file.

Parameters

[in]	dev	Switchtec device handle
[in]	type	Type of log data to dump
[in]	fd	File descriptor to dump the data to

Returns

0 on success, error code on failure

Definition at line 745 of file switchtec.c.

int switchtec_pff_to_port	(	struct switchtec_dev *	dev,
		int	pff,
		int *	partition,
		int *	port
	)

Convert a port function index to a partition and port number.

Parameters

[in]	dev	Switchtec device handle
[in]	pff	Port function number
[out]	partition	Partition number
[out]	port	Port number

Returns

0 on success, negative on failure

Definition at line 181 of file platform.c.

int switchtec_port_to_pff	(	struct switchtec_dev *	dev,
		int	partition,
		int	port,
		int *	pff
	)

Convert a partition and port number to a port function index.

Parameters

[in]	dev	Switchtec device handle
[in]	partition	Partition number
[in]	port	Port number
[out]	pff	Port function number

Returns

0 on success, negative on failure

Definition at line 196 of file platform.c.
