commit 90445ff6241e2a13445310803e2efa606c61f276 upstream. Crash detected on sam5d35 and its pmecc nand ecc controller. The problem was a call to chip->ecc.hwctl from nand_write_subpage_hwecc (nand_base.c) when we write a sub page. chip->ecc.hwctl function is not set when we are using PMECC controller. As a workaround, set NAND_NO_SUBPAGE_WRITE for PMECC controller in order to disable sub page access in nand_write_page.

2013-12-04mtd: gpmi: fix kernel BUG due to racing DMA operationsHuang Shijie
commit 7b3d2fb92067bcb29f0f085a9fa9fa64920a6646 upstream. [1] The gpmi uses the nand_command_lp to issue the commands to NAND chips. The gpmi issues a DMA operation with gpmi_cmd_ctrl when it handles a NAND_CMD_NONE control command. So when we read a page(NAND_CMD_READ0) from the NAND, we may send two DMA operations back-to-back. If we do not serialize the two DMA operations, we will meet a bug when 1.1) we enable CONFIG_DMA_API_DEBUG, CONFIG_DMADEVICES_DEBUG, and CONFIG_DEBUG_SG. 1.2) Use the following commands in an UART console and a SSH console: cmd 1: while true;do dd if=/dev/mtd0 of=/dev/null;done cmd 1: while true;do dd if=/dev/mmcblk0 of=/dev/null;done The kernel log shows below: ----------------------------------------------------------------- kernel BUG at lib/scatterlist.c:28!

The root cause of the bug: Assume process P issues DMA X, and sleep on the completion @this->dma_done. X's tasklet callback is dma_irq_callback. It firstly wake up the process sleeping on the completion @this->dma_done, and then trid to unmap the scatterlist S. The waked process P will issue Y in another ARM core. Y initializes S->sg_magic to zero with sg_init_one(), while dma_irq_callback is unmapping S at the same time. See the diagram: ARM core 0 | ARM core 1 ------------------------------------------------------------- (P issues DMA X, then sleep) --> | | (X's tasklet wakes P) --> | | | <-- (P begin to issue DMA Y) | (X's tasklet unmap the | scatterlist S with dma_unmap_sg) --> | <-- (Y calls sg_init_one() to init | scatterlist S) | [2] This patch serialize both the X and Y in the following way: Unmap the DMA scatterlist S firstly, and wake up the process at the end of the DMA callback, in such a way, Y will be executed after X. After this patch: ARM core 0 | ARM core 1 ------------------------------------------------------------- (P issues DMA X, then sleep) --> | | (X's tasklet unmap the | scatterlist S with dma_unmap_sg) --> | | (X's tasklet wakes P) --> | | | <-- (P begin to issue DMA Y) | | <-- (Y calls sg_init_one() to init | scatterlist S) | Signed-off-by: Huang Shijie <b32955@freescale.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-12-04mtd: nand: hack ONFI for non-power-of-2 dimensionsBrian Norris
commit 4355b70cf48363c50a9de450b01178c83aba8f6a upstream. Some bright specification writers decided to write this in the ONFI spec (from ONFI 3.0, Section 3.1): "The number of blocks and number of pages per block is not required to be a power of two. In the case where one of these values is not a power of two, the corresponding address shall be rounded to an integral number of bits such that it addresses a range up to the subsequent power of two value. The host shall not access upper addresses in a range that is shown as not supported." This breaks every assumption MTD makes about NAND block/chip-size dimensions -- they *must* be a power of two! And of course, an enterprising manufacturer has made use of this lovely freedom. Exhibit A: Micron MT29F32G08CBADAWP "- Plane size: 2 planes x 1064 blocks per plane - Device size: 32Gb: 2128 blockss [sic]" This quickly hits a BUG() in nand_base.c, since the extra dimensions overflow so we think it's a second chip (on my single-chip setup): ONFI param page 0 valid ONFI flash detected NAND device: Manufacturer ID: 0x2c, Chip ID: 0x44 (Micron MT29F32G08CBADAWP), 4256MiB, page size: 8192, OOB size: 744 ------------[ cut here ]------------ kernel BUG at drivers/mtd/nand/nand_base.c:203!

2013-09-26mtd: nand: fix NAND_BUSWIDTH_AUTO for x16 devicesBrian Norris
commit 68e8078072e802e77134664f11d2ffbfbd2f8fbe upstream. The code for NAND_BUSWIDTH_AUTO is broken. According to Alexander: "I have a problem with attach NAND UBI in 16 bit mode. NAND works fine if I specify NAND_BUSWIDTH_16 option, but not working with NAND_BUSWIDTH_AUTO option. In second case NAND chip is identifyed with ONFI." See his report for the rest of the details: http://lists.infradead.org/pipermail/linux-mtd/2013-July/047515.html Anyway, the problem is that nand_set_defaults() is called twice, we intend it to reset the chip functions to their x16 buswidth verions if the buswidth changed from x8 to x16; however, nand_set_defaults() does exactly nothing if called a second time. Fix this by hacking nand_set_defaults() to reset the buswidth-dependent functions if they were set to the x8 version the first time. Note that this does not do anything to reset from x16 to x8, but that's not the supported use case for NAND_BUSWIDTH_AUTO anyway.

commit 5ef4414f4bc26a19cfd5cd11aee9697a863e4d51 upstream. get_peb_for_wl() removes the PEB from the free list. If the WL subsystem detects that no wear leveling is needed it cancels the operation and drops the gained PEB. In this case we have to put the PEB back into the free list.

2013-09-14mtd: tegra-nor: Use staged read from NORManoj Chourasia
Most of the large read requests passed by upper MTD block layer are for highmem region which dma_map_single cannot handle. Those requests were getting serviced by memcpy_fromio, this was degrading performance. Moreover the memory region passed to dma_map_single should be on cache line boundaries. If the requirement is not met then system may crash due to cache incoherency. The approach added in this patch is to have a DMA coherent memory buffer. Read device via DMA to this coherent buffer and them memcpy it to user space pointer. This not only fixes some bugs but also enhances the NOR read performance. bug 928788 bug 898250 Signed-off-by: Manoj Chourasia <mchourasia@nvidia.com> Reviewed-on: http://git-master/r/76866 (cherry picked from commit 1491c0461a627c3bb63b01e126585eff9922ba1a) Change-Id: Ic8e24d2cc965f84bb97d2b6b29f27458aba17720 Reviewed-on: http://git-master/r/84026 Tested-by: Manoj Chourasia <mchourasia@nvidia.com> Reviewed-by: Varun Wadekar <vwadekar@nvidia.com> Rebase-Id: Ree1195ff059814e12710091201cae1df4ab661e9
