Partition(D4pccard)

Partition -- PC Card partition information

Syntax (Used with unsupported services)

   #include <sys/lcs.h>
   #include <sys/lss.h>

Description

The Partition structure is used to pass device information for a partition on a card in the specified socket based on the PC Card's CIS.

Structure definition

   unsigned short      usSocket;
   unsigned short      usAttributes;
   unsigned char       ucTupleMask;
   unsigned char       ucAccessSpeed;
   unsigned short      usFlags;
   unsigned long       ulLinkOffset;
   unsigned long       ulCISOffset;
   unsigned long       ulCardOffset;
   unsigned long       ulPartSize;
   unsigned long       ulEffBlockSize;
   unsigned short      usPartMultiple;
   unsigned short      usJedecID;
   unsigned short      usPartType;

Structure members

The members are defined as:

usSocket

Logical socket.

usAttributes

Partition attributes.

Bit 0

memory type (set=attribute, reset=common)

Bits 1-2

Resrved; reset to zero.

Bits 3-4

Prefetchable/cacheable

0: neither
1: prefetchable only
2: both
3: reserved

Bits 5-7

Reserved; reset to zero

Bit 8

Virtual paratition (set to one=true)

Bits 9-10

Write/erase interaction

0: write without erase
1: write with erase
2: reserved
3: write with disable erase

Bit 11

Write with verify

Bit 12

Erase requests supported

Bits 13-15

Base address register number (1-7)

ucTupleMask

Bit-mapped member.

Bit 0: access speed from tuples (set=true)
Bit 1: card offset from tuples (set=true)
Bit 2: port size from tuples (set-true)
Bit 3: EFF block size from tuples (set=true)
Bit 4: Port multiple from tuples (set=true)
Bit 6: JEDEC ID from tuples (set=true)
Bit 7: reserved; reset to zero
