Function Documentation

void sq_flush_range	(	unsigned long	start,
		unsigned int	len
	)

sq_flush_range - Flush (prefetch) a specific SQ range : the store queue address to start flushing from : the length to flush

Flushes the store queue cache from to + in a linear fashion.

unsigned long sq_remap	(	unsigned long	phys,
		unsigned int	size,
		const char *	name,
		pgprot_t	prot

void sq_unmap

(

unsigned long

vaddr

)

sq_unmap - Unmap a Store Queue allocation : Pre-allocated Store Queue mapping.

Unmaps the store queue allocation that was previously created by sq_remap(). Also frees up the pte that was previously inserted into the kernel page table and discards the UTLB translation.
