Detailed Description

Common definitions for MMC (Multimedia Commands). Applications include this for direct MMC access.

The documents we make use of are described in several specifications made by the SCSI committee T10 http://www.t10.org. In particular, SCSI Primary Commands (SPC), SCSI Block Commands (SBC), and Multi-Media Commands (MMC). These documents generally have a numeric level number appended. For example SPC-3 refers to ``SCSI Primary Commands - 3'.

In year 2010 the current versions were SPC-3, SBC-2, MMC-5.

◆ cdio_mmc_gpcmd_t

The opcode-portion (generic packet commands) of an MMC command.

In general, those opcodes that end in 6 take a 6-byte command descriptor, those that end in 10 take a 10-byte descriptor and those that in in 12 take a 12-byte descriptor.

(Not that you need to know that, but it seems to be a big deal in the MMC specification.)

Parameters
p_cdioCD structure set by cdio_open().
pp_sensereturns the sense bytes received from the drive. This is allocated memory or NULL if no sense bytes are available. Dispose non-NULL pointers by cdio_free() when no longer needed. See SPC-3 4.5.3 Fixed format sense data. SCSI error codes as of SPC-3 Annex D, MMC-5 Annex F: sense[2]&15 = Key , sense[12] = ASC , sense[13] = ASCQ

◆ mmc_read_cdtext()

uint8_t* mmc_read_cdtext ( const CdIo_t p_cdio)

Read cdtext information for a cdtext_t object.

This is the raw SCSI/MMC reply as retrieved by mmc_read_toc_cdtext(). It consists of 4 header bytes and a variable number of text packs.

The first two bytes of the header, a Big-Endian number, specifies the number of following bytes. The count also includes the next two header bytes which should be 0.

See also information in mmc_read_toc_cdtext().

Here is some code to parse the text packs into a cdtext_t object:

#include <cdio/mmc.h>
#include <cdio/cdtext.h>
reply = mmc_read_cdtext(p_cdio);
if (NULL != reply)
cdtext_data_init(p_cdtext, reply + 4,
(size_t) CDIO_MMC_GET_LEN16(reply) - 2);
Parameters
p_cdiothe CD object to be acted upon.
Returns
pointer to data on success, NULL on error or if CD-Text information does not exist.

Note: the caller must free the returned memory.

uint32_t  i_blocks 
)

Read just the user data part of some sort of data sector (via mmc_read_cd).

Parameters
p_cdioobject to read from
p_bufplace to read data into. The caller should make sure this location can store at least CDIO_CD_FRAMESIZE, M2RAW_SECTOR_SIZE, or M2F2_SECTOR_SIZE depending on the kind of sector getting read. If you don't know whether you have a Mode 1/2, Form 1/ Form 2/Formless sector best to reserve space for the maximum, M2RAW_SECTOR_SIZE.
i_lsnsector to read
i_blocksizesize of each block
i_blocksnumber of blocks to read

unsigned int  i_buf,
void *  p_buf 
)

Run a Multimedia command (MMC).

Parameters
p_cdioCD structure set by cdio_open().
i_timeout_mstime in milliseconds we will wait for the command to complete.
p_cdbCDB bytes. All values that are needed should be set on input. We'll figure out what the right CDB length should be.

p_bufBuffer for data, both sending and receiving.
Returns
0 if command completed successfully.

◆ mmc_run_cmd_len()

const mmc_cdb_t p_cdb,
unsigned int  i_cdb,
cdio_mmc_direction_t  e_direction,
unsigned int  i_buf,
void *  p_buf 
)

Run a Multimedia command (MMC) specifying the CDB length. The motivation here is for example ot use in is an undocumented debug command for LG drives (namely E7), whose length is being miscalculated by mmc_get_cmd_len(); it doesn't follow the usual code number to length conventions. Patch supplied by SukkoPera.

Parameters
p_cdioCD structure set by cdio_open().
i_timeout_mstime in milliseconds we will wait for the command to complete.
p_cdbCDB bytes. All values that are needed should be set on input.

p_bufBuffer for data, both sending and receiving.
Returns
0 if command completed successfully.

driver_return_code_t mmc_set_blocksize ( const CdIo_t p_cdio,
uint16_t  i_blocksize 
)

Set the block size for subsequest read requests, via MMC.
