int spu_activate	(	struct spu_context *	ctx,
		unsigned long	flags
	)

spu_activate - find a free spu for a context and execute it : spu context to schedule : flags (currently ignored)

Tries to find a free spu to run . If no free spu is available add the context to the runqueue so it gets woken up once an spu is available.

int spu_init_csa ( struct spu_state * csa )

spu_alloc_csa - allocate and initialize an SPU context save area.

Allocate and initialize the contents of an SPU context save area. This includes enabling address translation, interrupt masks, etc., as appropriate for the given OS environment.

Note that storage for the 'lscsa' is allocated separately, as it is by far the largest of the context save regions, and may need to be pinned or otherwise specially aligned.

Definition at line 2198 of file switch.c.

spu_release_saved - unlock spu context and return it to the runqueue : context to unlock

Definition at line 178 of file context.c.

int spu_restore	(	struct spu_state *	new,
		struct spu *	spu
	)

spu_restore - SPU context restore, with harvest and locking. : pointer to SPU context save area, to be restored. : pointer to SPU iomem structure.

Perform harvest + restore, as we may not be coming from a previous successful save operation, and the hardware state is unknown.

Definition at line 2132 of file switch.c.

int spu_save	(	struct spu_state *	prev,
		struct spu *	spu
	)

spu_save - SPU context save, with locking. : pointer to SPU context save area, to be saved. : pointer to SPU iomem structure.

Acquire locks, perform the save operation then return.
