Subject: UBI Fastmap updates
Date: Mon, 18 Jun 2012 18:18:43 +0200 [thread overview]
Message-ID: <1340036345-96726-1-git-send-email-richard@nod.at> (raw)
This is the next round of UBI fastmap updates.
It contains mostly fixes.
The highlights are:
- ubi_wl_flush() is no longer needed before creating the fastmap
- It passes all tests (ubi-tests, my own tests) with bit flit emulation and UBI self checks enabled.
- If UBI self checks are enabled UBI is able to proof the correctness of an EBA created from by fastmap.
- Endianness has been successfully tested (using qemu-x86 and qemu-ppc)
If you want to test fastmap you can use my git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rw/ubi2.git ubi2/v11
Please don't get confused with the release number, v11 is the internal release.
Fastmap has been tested on PPC, ARM, x86 on both real hardware and emulation using qemu.
To catch race conditions lots of tests have been done on a very fast x86 multi core machine.
So far nothing exploded. :-)
I'll send my fastmap torture script plus a paranoia patch in a separate mail.
Enjoy!
