libjedec_vendor_string —
translate JEDEC vendor IDs to strings
library “libjedec”
#include
<libjedec.h>
const char *
libjedec_vendor_string(uint_t
cont, uint_t vendor);
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 JEP106BH data from September 2023.
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.
