Detailed Description

Manage domain spanning cores.

Function Documentation

void disp_get_eh_frame	(	lvaddr_t *	eh_frame,
		size_t *	eh_frame_size
	)

returns the address and the size of the EH frame

Parameters

eh_frame	returned virtual address of the EH frame
eh_frame_size	returned size of the EH frame

void disp_get_eh_frame_hdr	(	lvaddr_t *	eh_frame_hdr,
		size_t *	eh_frame_hdr_size
	)

returns the address and the size of the EH frame header

Parameters

eh_frame	returned virtual address of the EH frame
eh_frame_size	returned size of the EH frame

void disp_set_core_id

(

coreid_t

core_id

)

set the core_id.

Code using this should do a kernel_cap invocation to get the core_id first.

errval_t domain_init

(

void

)

Initialize the domain library.

Registers a iref with the monitor to offer the interdisp service on this core Does not block for completion.

errval_t domain_new_dispatcher	(	coreid_t	core_id,
		domain_spanned_callback_t	callback,
		void *	callback_arg
	)

Creates a dispatcher on a remote core.

Parameters

core_id	Id of the core to create the dispatcher on
callback	Callback to use when new dispatcher is created

The new dispatcher is created with the same vroot, sharing the same vspace. The new dispatcher also has a urpc connection to the core that created it.
