* mtd: fix a huge latency problem in the MTD CFI and LPDDR flash drivers.Stefani Seibold2010-05-106-240/+237
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The use of a memcpy() during a spinlock operation will cause very long thread context switch delays if the flash chip bandwidth is low and the data to be copied large, because a spinlock will disable preemption. For example: A flash with 6,5 MB/s bandwidth will cause under ubifs, which request sometimes 128 KiB (the flash erase size), a preemption delay of 20 milliseconds. High priority threads will not be served during this time, regardless whether this threads access the flash or not. This behavior breaks real time. The patch changes all the use of spin_lock operations for xxxx->mutex into mutex operations, which is exact what the name says and means. I have checked the code of the drivers and there is no use of atomic pathes like interrupt or timers. The mtdoops facility will also not be used by this drivers. So it is dave to replace the spin_lock against mutex. There is no performance regression since the mutex is normally not acquired.

* mtd/nand/fsl_upm: Replace the dangerous to_fsl_upm_nand macroFerenc Wagner2010-05-101-1/+4
| | | | | | | | | | The original macro worked only when applied to variables named 'mtd'. While this could have been fixed by simply renaming the macro argument, a more type-safe replacement is preferred.

* mtd: OneNAND: OMAP2/3: unmap correct DMA bufferMika Westerberg2010-05-101-4/+4
| | | | | | | | | | | | | | Functions omap2_onenand_write_bufferram() and omap3_onenand_write_bufferram() map the write buffer and store the returned handle in variable dma_src. However, when DMA unmap is done, variable dma_dst is used instead of the correct dma_src. This patch fixes them to use the correct DMA buffer.

* mtd/maps/physmap: catch failure to register MTD_PHYSMAP_COMPAT deviceH Hartley Sweeten2010-04-201-2/+5
| | | | | | | | | | | | | | If the default Kconfig values are used with MTD_PHYSMAP_COMPAT you end up with a resource where end < start. This causes __request_resource to return a conflict which then returns an -EBUSY error code. The current physmap.c code just assumes that the platfom_device_register will always succeed. Catch this failure during the physmap_init and propogate the error.

* bitops: rename for_each_bit() to for_each_set_bit(): mtdAkinobu Mita2010-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | Rename for_each_bit() to for_each_set_bit in the kernel source tree. To permit for_each_clear_bit(), should that ever be added. I'll be sending a patch to Linus this week which removes the temporary for_each_bit() macro, so this patch will be needed to avoid build breakage.

Namely, if @ubi->dev is not initialized, we have to free everything ourselves. But if it was, we should not free the @ubi object, because it will be freed in the 'dev_release()' function. And we did not get this situation right. This patch introduces additional argument to the 'uif_init()' function. On exit, this argument indicates whether the final 'free(ubi)' will happen in 'dev_release()' or not. So the caller always knows how to properly release the resources. Impact: all memory is now correctly released when UBI fails to attach an MTD device. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* | | mtd: Make SM_FTL depend on MTD_NANDDavid Woodhouse2010-03-091-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Randy Dunlap observed a build problem with the following config: CONFIG_SM_FTL=y CONFIG_SM_FTL_MUSEUM=y CONFIG_MTD_NAND=m The ECC calculation routines are then built as a module, but referenced by the sm_ftl code in the kernel, resulting in a build failure. The simple fix is to make CONFIG_SM_FTL depend on MTD_NAND unconditionally -- it's pointless without hardware support anyway. Fix some typos which Randy pointed out, too.
