Add APIs to enable/disable a channel and switch to or preempt a specific TSG

Adds: - /proc/preempt_tsg which takes a TSG ID - /proc/disable_channel which takes a channel ID - /proc/enable_channel which takes a channel ID - /proc/switch_to_tsg which takes a TSG ID Also significantly expands documentation and structs available in nvdebug.h.

FUNCTION The AES algorithm Rijndael implemented for block and key sizes of 128 bits (16 bytes) by Brian Gladman. This is an implementation of the AES encryption algorithm (Rijndael) designed by Joan Daemen and Vincent Rijmen. 2. THE CIPHER INTERFACE byte (an unsigned 8-bit type) word (an unsigned 32-bit type) aes_ret: (a signed 16 bit type for function return values) aes_good (value != 0, a good return) aes_bad (value == 0, an error return) enum aes_key: (encryption direction) enc (set key for encryption) dec (set key for decryption) both (set key for both) class or struct aes (structure for context) C subroutine calls: aes_ret set_blk(const word block_length, aes *cx) (variable block size) aes_ret set_key(const byte key[], const word key_length, const enum aes_key direction, aes *cx) aes_ret encrypt(const byte input_blk[], byte output_blk[], const aes *cx) aes_ret decrypt(const byte input_blk[], byte output_blk[], const aes *cx) IMPORTANT NOTE: If you are using this C interface and your compiler does not set the memory used for objects to zero before use, you will need to ensure that cx.mode is set to zero before using the C subroutine calls. The block length inputs to set_block and set_key are in numbers of BYTES, not bits. The calls to subroutines must be made in the above order but multiple calls can be made without repeating earlier calls if their parameters have not changed. If the cipher block length is variable but set_blk has not been called before cipher operations a value of 16 is assumed (that is, the AES block size). In contrast to earlier versions the block and key length parameters are now checked for correctness and the encryption and decryption routines check to ensure that an appropriate key has been set before they are called. */ #ifndef _AES_H #define _AES_H /* The only supported block size for the benchmark is 16 */ #define BLOCK_SIZE 16 /* The number of key schedule words for different block and key lengths (allowing for the method of computation which requires the length to be a multiple of the key length): Key Schedule key length (bytes) Length 16 20 24 28 32 --------------------- block 16 | 44 60 54 56 64
