Function Documentation

◆ amdsmi_get_gpu_ecc_count()

amdsmi_status_t amdsmi_get_gpu_ecc_count	(	amdsmi_processor_handle	processor_handle,
		amdsmi_gpu_block_t	block,
		amdsmi_error_count_t *	ec
	)

Retrieve the error counts for a GPU block. It is not supported on virtual machine guest.

Given a processor handle processor_handle, an amdsmi_gpu_block_t block and a pointer to an amdsmi_error_count_t ec, this function will write the error count values for the GPU block indicated by block to memory pointed to by ec.

Parameters

[in]	processor_handle	a processor handle
[in]	block	The block for which error counts should be retrieved
[in,out]	ec	A pointer to an amdsmi_error_count_t to which the error counts should be written If this parameter is nullptr, this function will return AMDSMI_STATUS_INVAL if the function is supported with the provided, arguments and AMDSMI_STATUS_NOT_SUPPORTED if it is not supported with the provided arguments.

Returns

amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

◆ amdsmi_get_gpu_ecc_enabled()

amdsmi_status_t amdsmi_get_gpu_ecc_enabled	(	amdsmi_processor_handle	processor_handle,
		uint64_t *	enabled_blocks
	)

Retrieve the enabled ECC bit-mask. It is not supported on virtual machine guest.

Given a processor handle processor_handle, and a pointer to a uint64_t enabled_mask, this function will write bits to memory pointed to by enabled_blocks. Upon a successful call, enabled_blocks can then be AND'd with elements of the amdsmi_gpu_block_t ennumeration to determine if the corresponding block has ECC enabled. Note that whether a block has ECC enabled or not in the device is independent of whether there is kernel support for error counting for that block. Although a block may be enabled, but there may not be kernel support for reading error counters for that block.

Parameters

[in]	processor_handle	a processor handle
[in,out]	enabled_blocks	A pointer to a uint64_t to which the enabled blocks bits will be written. If this parameter is nullptr, this function will return AMDSMI_STATUS_INVAL if the function is supported with the provided, arguments and AMDSMI_STATUS_NOT_SUPPORTED if it is not supported with the provided arguments.

Returns

amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

◆ amdsmi_get_gpu_ecc_status()

amdsmi_status_t amdsmi_get_gpu_ecc_status	(	amdsmi_processor_handle	processor_handle,
		amdsmi_gpu_block_t	block,
		amdsmi_ras_err_state_t *	state
	)

Retrieve the ECC status for a GPU block. It is not supported on virtual machine guest.

Given a processor handle processor_handle, an amdsmi_gpu_block_t block and a pointer to an amdsmi_ras_err_state_t state, this function will write the current state for the GPU block indicated by block to memory pointed to by state.

Parameters

[in]	processor_handle	a processor handle
[in]	block	The block for which error counts should be retrieved
[in,out]	state	A pointer to an amdsmi_ras_err_state_t to which the ECC state should be written If this parameter is nullptr, this function will return AMDSMI_STATUS_INVAL if the function is supported with the provided, arguments and AMDSMI_STATUS_NOT_SUPPORTED if it is not supported with the provided arguments.

Returns

amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail

◆ amdsmi_status_code_to_string()

amdsmi_status_t amdsmi_status_code_to_string	(	amdsmi_status_t	status,
		const char **	status_string
	)

Get a description of a provided AMDSMI error status.

Set the provided pointer to a const char *, status_string, to a string containing a description of the provided error code status.

Parameters

[in]	status	The error status for which a description is desired
[in,out]	status_string	A pointer to a const char * which will be made to point to a description of the provided error code

Returns

amdsmi_status_t | AMDSMI_STATUS_SUCCESS on success, non-zero on fail
