Enumeration Type Documentation

enum block_state

enum block_state - blocking state : non blocking : blocking

These states are for ioctls that need to wait for a response from firmware, so they probably require sleep.

Enumerator:

NON_BLOCKING
BLOCKING
need_more
block_done
finish_started
finish_done

Function Documentation

void mpt2sas_ctl_add_to_event_log	(	struct MPT2SAS_ADAPTER *	ioc,
		Mpi2EventNotificationReply_t *	mpi_reply
	)

mpt2sas_ctl_add_to_event_log - add event : per adapter object : reply message frame

Return nothing.

Definition at line 348 of file mpt2sas_ctl.c.

u8 mpt2sas_ctl_done	(	struct MPT2SAS_ADAPTER *	ioc,
		u16	smid,
		u8	msix_index,
		u32	reply
	)

mpt2sas_ctl_done - ctl module completion routine : per adapter object : system request message index : MSIX table index supplied by the OS : reply message frame(lower 32bit addr) Context: none.

The callback handler when using ioc->ctl_cb_idx.

Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from this function.

Definition at line 274 of file mpt2sas_ctl.c.

u8 mpt2sas_ctl_event_callback	(	struct MPT2SAS_ADAPTER *	ioc,
		u8	msix_index,
		u32	reply
	)

mpt2sas_ctl_event_callback - firmware event handler (called at ISR time) : per adapter object : MSIX table index supplied by the OS : reply message frame(lower 32bit addr) Context: interrupt.

This function merely adds a new work task into ioc->firmware_event_thread. The tasks are worked from _firmware_event_work in user context.

Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from this function.

void mpt2sas_ctl_exit

(

void

)

mpt2sas_ctl_exit - exit point for ctl

Definition at line 3065 of file mpt2sas_ctl.c.

void mpt2sas_ctl_init

(

void

)

mpt2sas_ctl_init - main entry point for ctl.

Definition at line 3050 of file mpt2sas_ctl.c.

void mpt2sas_ctl_reset_handler	(	struct MPT2SAS_ADAPTER *	ioc,
		int	reset_phase
	)

mpt2sas_ctl_reset_handler - reset callback handler (for ctl) : per adapter object : phase

The handler for doing any required cleanup or initialization.

The reset phase can be MPT2_IOC_PRE_RESET, MPT2_IOC_AFTER_RESET, MPT2_IOC_DONE_RESET

Definition at line 447 of file mpt2sas_ctl.c.

void mpt2sas_enable_diag_buffer	(	struct MPT2SAS_ADAPTER *	ioc,
		u8	bits_to_register
	)

mpt2sas_enable_diag_buffer - enabling diag_buffers support driver load time : per adapter object : bitwise field where trace is bit 0, and snapshot is bit 1

This is called when command line option diag_buffer_enable is enabled at driver load time.
