2008-04-08mtd/chips: add missing set_current_state() to cfi_{amdstd,staa}_sync()Dmitry Adamushko
cfi_amdstd_sync() and cfi_staa_sync() call schedule() without changing task's state appropriately. In case of e.g. chip->state == FL_ERASING, cfi_*_sync() will be busy-looping either redundantly for a fixed interval of time (for SCHED_NORMAL tasks) or possibly endlessly (for RT tasks and UP).

2008-04-04mtd: fix broken state in CFI driver caused by FL_SHUTDOWNAlexey Korolev
THe CFI driver in 2.6.24 kernel is broken. Not so intensive read/write operations cause incomplete writes which lead to kernel panics in JFFS2. We investigated the issue - it is caused by bug in FL_SHUTDOWN parsing code. Sometimes chip returns -EIO as if it is in FL_SHUTDOWN state when it should wait in FL_PONT (error in order of conditions). The following patch fixes the bug in state parsing code of CFI. Also I've added comments to notify developers if they want to add new case in future.

2008-02-03[MTD] Unlocking all Intel flash that is locked on power up.Justin Treon
Patch for unlocking all Intel flash that has instant locking on power up. The patch has been tested on Intel M18, P30 and J3D Strata Flash. 1. The automatic unlocking can be disabled for a particular partition in the map or the command line. a. For the bit mask in the map it should look like: .mask_flags = MTD_POWERUP_LOCK, b. For the command line parsing it should look like: mtdparts=0x80000(bootloader)lk 2. This will only unlock parts with instant individual block locking. Intel parts with legacy unlocking will not be unlocked.

The bug causes corruptions of data read from flash. The original code performs cache invalidation from "adr" to "adr + len" in do_write_buffer(). Since len and adr could be updated in the code before invalidation - it causes improper setting of cache invalidation regions.

2007-11-26[MTD] [NOR] Prevent erase command invocation on suspended chipAlexander Belyakov
while running stress tests we have met cfi_cmdset_0001.c driver issue. Working on multipartitional devices with erase suspend on write feature enabled it is possible to get erase operation invoked on chip with suspended erase. get_chip() looses information about earlier suspended erase and new erase operation gets issued. New erase operations report successful completion, but blocks remain dirty causing, for example, JFFS2 error messages like: ... Newly-erased block contained word 0x20031985 at offset 0x00200000 Newly-erased block contained word 0x20031985 at offset 0x00280000 Newly-erased block contained word 0x20031985 at offset 0x00240000 ...

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

Fix of performance and stability issues on Intel NOR chips. It fixes: 1. Very low write performance on Sibley (perf tests demonstrated write performance less than 100Kb/sec when it should be over 400Kb/sec). 2. Low erase performance. (perf tests on Sibleuy demonstrated erase performance 246Kb/sec when it should be over 300Kb/sec). 3. Error on JFFS2 tests with CPU loading application when MTD returns "block erase error: (status timeout)" To fix the issue it does the following: 1. Removes the timeout tuning from inval_cache_and_wait_for_operation. 2. Waiting conditions in inval_cache_and_wait_for_operation now is based on timer resolution If timeout is lower than timer resolution then we do in cycle "Checking the status" udelay(1); cond_resched(); If timeout is greater than timer resolution (probably erase operation) We do the following sleep for half of operation timeout and do in cycle the following "Checking the status" sleep for timer resolution Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Alexey Korolev <akorolev@infradead.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
