Subject: [PATCH 1260/1350] drivers: mmc: disable write-caching on Samsung 2023
|
|
model year SD cards
|
|
|
|
Samsung EVO Plus, Pro Plus and Evo Ultimate cards of this era appear to
|
|
have a broken cache-flush implementation when operating in CQ mode.
|
|
|
|
Unfortunately the cards seem to use a separate CID name string for every
|
|
variant and capacity, so nobble the cache feature for this MANFID, OEMID
|
|
and year. Turning this off seems to have negligible impact on
|
|
random-write throughput in non-CQ mode.
