Subject: RFC: [PATCH V2 0/9 Integration of SmartMedia/xD into mtd subsystem
Date: Fri, 08 Jan 2010 17:04:52 +0200 [thread overview]
Message-ID: <1262963092.12577.14.camel@maxim-laptop> (raw)
Hi,
This is second version of my patchset.
Changes since V1:
-> Ported to latest kernel revision (2.6.33-rc3)
-> Resolved problem with oob layout
-> Resoved all checkpatch.pl issues
-> Tested that indeed all hardware devices of this type have
same PCI ID
Remaining issues:
* Write speed is of course still very low, but like I said, it might be
hardware problem.
* No support for 256 byte SmartMedia in the FTL. I don't have the
hardware to test that, and I think for now there is not much need for
that.
(It only applies to 1MB and 2MB SmartMedia devices anyway...)
* Like I said some XD cards are fake, thus have to be used with the FTL,
This is a hardware problem too.
If I knew which xD cards are affected, and had a way to know for sure
they have an FTL inside, I could implement a fake FTL, thus gain higher
write speed (and maybe solve that way issue #1)
Best regards,
Maxim Levitsky
