| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When truncating an UBI volume, UBI should allocates a PEB-sized buffer but does not release it, which leads to memory leaks. This patch fixes the issue.

| |/ | | | | | | | | | | | | | | | | | | | | The in kernel copy of a volume's update marker is not initialised from the volume table. This means that volumes where an update was unfinnished will not be treated as "forbidden to use". This is basically that the update functionality was broken.

| * mtd: Really add ARM pismo supportRussell King - ARM Linux2010-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Commit 7cb777a3d71f9d1f7eb149c7a504d21f24219ae8 (mtd: add ARM pismo support) intended to add this, but seems only to have patched the Makefile without touching Kconfig or providing any code...) The following patch adds support for PISMO modules found on ARM Ltd development platforms. These are MTD modules, and can have a selection of SRAM, flash or DOC devices as described by an on-board I2C EEPROM. We support SRAM and NOR flash devices only by registering appropriate conventional MTD platform devices as children of the 'pismo' device.

| * kmsg_dump: Dump on crash_kexec as wellKOSAKI Motohiro2009-12-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NAND controller has some limitations how to access the internal buffers. It only allows 32 bit accesses. The driver used to work around this by having special alignment aware copy routines. We now copy the whole page to a buffer in memory and let the access functions use this buffer. This simplifies the driver. A bonnie++ test showed that this has no negative performance impact on the driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

They honored the fact that the bad block marker on 8bit flashes is on byte 5 while on 16bit flashes it is on byte 11. In the Kernel driver this was copied wrong and we ended up with two identical descriptions. Change it so that we have only one description which leaves byte 5 and byte 11 unspecified so that it won't be used by others. Also, rename the descriptions to nand_hw_eccoob_smallpage and nand_hw_eccoob_largepage so that it can't be confused with Nand chip bus widths (what actually happened in this driver) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | mtd: mtdoops: refactor as a kmsg_dumperSimon Kagstrom2009-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last messages which happens before a crash might contain interesting information about the crash. This patch reworks mtdoops using the kmsg_dumper support instead of a console, which simplifies the code and also includes the messages before the oops started. On oops callbacks, the MTD device write is scheduled in a work queue (to be able to use the regular mtd->write call), while panics call mtd->panic_write directly. Thus, if panic_on_oops is set, the oops will be written out during the panic. A parameter to specify which mtd device to use (number or name), as well as a flag, writable at runtime, to toggle wheter to dump oopses or only panics (since oopses can often be handled by regular syslog). The patch was massaged and amended by Artem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one sits in my tree for more than two years... Using device code found on page 12 (http://www.btdesigner.com/pdfs/M29W800D.pdf) and unlock address from page 15 MTD subsytem happily detects ST M29W800DB in 16-bit mode. I do believe original author used only 8-bit mode and thus didn't hit this bug. Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
