2008-01-26[MTD] [NAND] fix s3c2410 error correctionMatt Reimer
The single-bit error correction was, well, incorrect. For determing which bit to correct it was using P1' P2' P4' P8' instead of P1 P2 P4 P8, and it was using P16' P32' P64' P128' P256' P512' P1024' P2048' instead of P16 P32 P64 P128 P256 P512 P1024 P2048.

2008-01-12[MTD] [NAND] make s3c2410 indicate an error for multi-bit read errorsMatt Reimer
If there were multiple bit errors in the data s3c2410_nand_correct_data() was returning 0 (no error) instead of -1, so the upper layers (like JFFS2) would not know the data is corrupt. Signed-off-by: Matt Reimer <mreimer@vpop.net> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2008-01-08[MTD] [NAND] Don't panic if a controller driver does ecc its own way.Scott Wood
Some hardware, such as the enhanced local bus controller used on some mpc83xx chips, does ecc transparently when reading and writing data, rather than providing a generic calculate/correct mechanism that can be exported to the nand subsystem. The subsystem should not BUG() when calculate, correct, or hwctl are missing, if the methods that call them have been overridden.

This is to ensure that the NAND is kept in lowest power mode over suspend (power settings are only specified for nFCE inactive) as well as fixing the Simtec Osiris which relies on nFCE being inactive.

2007-09-06[MTD] [NAND] nandsim: avoid deadlocking FSArtem Bityutskiy
Make nandsim use GFP_NOFS when allocating memory, because it might be used by a file-system (e.g. UBIFS2) which means, if we are short of memory, we may deadlock. Indee, UBIFS is holding a lock, writes to the media, reaches this place in NANDsim, kmalloc does not find the requested amount of RAM, calls memory shrinker, which decides to writeback inodes, calls FS, and it deadlocks on the lock which is already being held. Below is the UBIFS backtrace which demonstrates that: [<c03717dc>] __mutex_lock_slowpath+0xc8/0x2e6 [<c0371a16>] mutex_lock+0x1c/0x1f [<f8b9d076>] reserve_space+0x3d/0xa9 [ubifs] [<f8b9d1bd>] make_one_reservation+0x2b/0x86 [ubifs] [<f8b9d3fc>] ubifs_jrn_write_block+0xda/0x12f [ubifs] [<f8b9ff3a>] ubifs_writepage+0x11d/0x1ec [ubifs] [<c015d6ab>] shrink_inactive_list+0x7fa/0x969 [<c015d8c8>] shrink_zone+0xae/0x10c [<c015e3b4>] try_to_free_pages+0x159/0x251 [<c015980a>] __alloc_pages+0x125/0x2f0 [<c016ff6a>] cache_alloc_refill+0x380/0x6ba [<c01703f3>] __kmalloc+0x14f/0x157 [<f885722a>] do_state_action+0xab7/0xc74 [nandsim] [<f885760c>] switch_state+0x225/0x402 [nandsim] [<f8857e7e>] ns_hwcontrol+0x3e2/0x620 [nandsim] [<f8862f53>] nand_command+0x2e/0x1a5 [nand] [<f8861ad8>] nand_write_page+0x4a/0x9a [nand] [<f88617b4>] nand_do_write_ops+0x1cf/0x343 [nand] [<f8861a70>] nand_write+0x88/0xa6 [nand] [<f8850b0e>] part_write+0x72/0x8b [mtd] [<f88e19c5>] ubi_io_write+0x189/0x29c [ubi] [<f88dfb98>] ubi_eba_write_leb+0xb6/0x699 [ubi] [<f88def93>] ubi_leb_write+0xe4/0xe9 [ubi] [<f8ba3b82>] ubifs_wbuf_write_nolock+0x333/0x4c9 [ubifs] [<f8b9d28c>] write_node+0x74/0x8e [ubifs] [<f8b9d422>] ubifs_jrn_write_block+0x100/0x12f [ubifs] [<f8b9ff3a>] ubifs_writepage+0x11d/0x1ec [ubifs] [<c0159e5b>] __writepage+0xb/0x26 [<c015a318>] write_cache_pages+0x203/0x2d9 [<c015a411>] generic_writepages+0x23/0x2d [<c015a452>] do_writepages+0x37/0x39 [<c018e24a>] __writeback_single_inode+0x96/0x399 [<c018e903>] sync_sb_inodes+0x1a3/0x274 [<c018ebf3>] writeback_inodes+0xa6/0xd8 [<c015a9dd>] background_writeout+0x86/0x9e [<c015ae9c>] pdflush+0xfb/0x1b6 [<c01387d7>] kthread+0x37/0x59 [<c0104dc3>] kernel_thread_helper+0x7/0x14 The deadlock is funny because it starts in pdflush/writeback, and comes back to writeback, then deadlocks.

Unlike most stuff on the market the chip inside these two allows raw flash access and doesn't implement and FTL, leaving that functionality to the device driver. Raw flash access in a cheap USB cardreader! An MTD test device one can attach to a PC! What a deal! The command set of the chip is not documented, so information was obtained from the existing mass-storage driver (drivers/usb/storage/alauda.c), its documentation (http://alauda.sourceforge.net/wikka.php?wakka=BulkCommandReference), additional reverse engineering and comparison with a vendor driver for a related chip (http://www.ratocsystems.com/english/download/driver/linux/sma03u.html).

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have. Note that this patch depends on another header fixup patch I submitted to LKML yesterday: [PATCH] scatterlist.h needs types.h http://lkml.org/lkml/2007/3/01/141 Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Badari Pulavarty <pbadari@us.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
