LIBJEDEC_VENDOR_STRING(3JEDEC) JEDEC Support Library Functions

NAME

libjedec_vendor_string - translate JEDEC vendor IDs to strings

LIBRARY

JEDEC Support Library Functions (libjedec, -ljedec)

SYNOPSIS

#include <libjedec.h>

const char *
libjedec_vendor_string(uint_t cont, uint_t vendor);

DESCRIPTION

The libjedec_vendor_string() function translates a JEDEC vendor ID into
a corresponding name. JEDEC vendor IDs are defined in the JEP106
standard. Vendor IDs come in banks and each bank contains up to 126
unique vendor names. To accommodate more than 126 vendors, a series of
continuation bytes -- repeated values of 0x7f -- are used to indicate
the bank. Most implementations, like SPD data, don't actually encode
multiple continuations in the data, but rather just how many
continuations are present. Note, the JEP106 standard describes the
first bank as bank 1; however, the library is phrased in terms of the
number of continuations due to how hardware encodes this data.

The value in cont should indicate the number of continuations present.
The value in vendor indicates the vendor to look for and should include
its parity bit. When the name is successfully found, a pointer to a
constant string with the vendor's current name is returned. Note that
a given vendor's name may be changed over time due to acquisitions.
When the value doesn't correspond to a known name then NULL is
returned.

Currently the data reflects the JEP106BK data from September 2024.

RETURN VALUES

Upon successful completion, the libjedec_vendor_string() function
returns a pointer to a vendor's name. Otherwise NULL is returned to
indicate that there is no mapping for the specified IDs.
