MMC updates for 2.6.40-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc.git for-linus

to receive the MMC merge for 2.6.40-rc1.  There are currently no merge
conflicts, and the patches have been tested in linux-next.  Thanks.

Highlights are:
Core:
 * eMMC 4.4 "boot partition" support.  This exposes an eMMC device's
   boot partitions, which are accessed separately from the other
   partitions as (e.g.) /dev/mmcblk0boot0.  There's a strong potential
   for bricking the device you're running on by writing to these (they
   are usually used by the bootloader), so we disable write access by
   default.  To write to them, first perform:
     # echo 0 > /sys/block/mmcblkXbootY/force_ro
 
 * An ioctl for running MMC CMD/ACMDs from userspace (with CAP_SYS_RAWIO).
   This is primarily useful for enabling built-in security functionality
   on SD cards.

 * A new per-*card* quirks mechanism, along with two cases where this is
   necessary:  one where some Sandisk cards handle erase/trim arguments
   differently, and one where the same optimization (CMD23 multiblock
   transfers) causes a large (50%, for some tests) performance increase
   on SanDisk cards and a small performance *decrease* on others.

 * Reliable write support for MMC cards, servicing REQ_FUA/REQ_META
   requests.

 * eMMC Dual Data Rate support.

Drivers:
 * SD v3.0 improvements, with support for SDXC cards at ultra-high-speed
   (up to 104MB/sec) modes.  Thanks to Arindam Nath at AMD for this
   patchset, also Andrei Warkentin at Motorola and Philip Rakity at
   Marvell.

 * New "vub300" driver for Elan Digital Systems' VUB300 chip, which is
   a USB connected SDIO/SD/MMC host controller.

 * tmio_mmc, sh_mmcif: Runtime and system-wide suspend support.
