Subject: write buffer for MTD devices?
Date: Thu, 5 Jul 2007 13:36:04 +0900 [thread overview]
Message-ID: <20070705043604.GA10478@pooky.senux.com> (raw)
Hi,
You know that block devices such as hard disk has write buffer
in hard disk itself to speed up the write performance.
(The write buffer speed up when it works in write-back mode.)
My questions are: (only for NAND flash memory)
1) Then, does MTD devices has write buffer in device itself?
2) If ret->mtd->write() returns OK, is the data sent by user
successfully written on flash memory media? (not cache or
buffer)
Any comments, related matrials or URLs are needed.
