sceKernelDcacheInvalidateAll()

void sceKernelDcacheInvalidateAll

(

void

)

Invalidate the entire data cache.

sceKernelDcacheProbe()

int sceKernelDcacheProbe

(

void *

addr

)

Check whether the specified address is in the data cache.

Parameters

addr	- The address to check

Returns

0 = not cached, 1 = cache

sceKernelDeflateDecompress()

int sceKernelDeflateDecompress	(	u8 *	dest,
		u32	destSize,
		const u8 *	src,
		u8 **	src_out )

Decompress deflate'd data (requires kernel mode)

Parameters

dest	- pointer to destination buffer
destSize	- size of destination buffer
src	- pointer to source (compressed) data
src_out	- if not NULL, it will store the pointer to src + compressed_bytes_processed

Returns

size decompressed on success, < 0 on error

sceKernelGzipDecompress()

int sceKernelGzipDecompress	(	u8 *	dest,
		u32	destSize,
		const u8 *	src,
		u8 **	src_out )

Decompress gzip'd data (requires kernel mode)

Parameters

dest	- pointer to destination buffer
destSize	- size of destination buffer
src	- pointer to source (compressed) data
src_out	- if not NULL, it will store the pointer to src + compressed_bytes_processed

Returns

size decompressed on success, < 0 on error

sceKernelIcacheInvalidateAll()

void sceKernelIcacheInvalidateAll

(

void

)

Invalidate the entire instruction cache.

sceKernelIcacheInvalidateRange()

void sceKernelIcacheInvalidateRange	(	const void *	addr,
		unsigned int	size )

Invalidate a instruction cache range.

Parameters

addr	- The start address of the range.
size	- The size in bytes

sceKernelIcacheProbe()

int sceKernelIcacheProbe

(

const void *

addr

)

Check whether the specified address is in the instruction cache.

Parameters

addr	- The address to check

Returns

0 = not cached, 1 = cache
