| | | | | | | | | | | | | | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

| * | USB: convert some miscellanies drivers to use module_usb_driver()Greg Kroah-Hartman2011-11-181-12/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the remaining USB drivers in the kernel to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

| * mtd: nand: initialize ops.modeBrian Norris2011-10-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our `ops' information was converted to a local variable recently, and apparently, old code relied on the fact that the global version was often left in a valid mode. We can't make this assumption on local structs, and we shouldn't be relying on a previous state anyway. Instead, we initialize mode to 0 for don't-care situations (i.e., the operation does not use OOB anyway) and MTD_OPS_PLACE_OOB when we want to place OOB data. This fixes a bug with nand_default_block_markbad(), where we catch on the BUG() call in nand_fill_oob(): Kernel bug detected[#1]: ...

| * mtd: nand: invalidate cache on unaligned readsBrian Norris2011-09-211-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In rare cases, we are given an unaligned parameter `from' in `nand_do_read_ops()'. In such cases, we use the page cache (chip->buffers->databuf) as an intermediate buffer before dumping to the client buffer. However, there are also cases where this buffer is not cleanly reusable. In those cases, we need to make sure that we explicitly invalidate the cache. This patch prevents accidental reusage of the page cache, and for me, this solves some problems I come across when reading a corrupted BBT from flash (NAND_BBT_USE_FLASH and NAND_BBT_NO_OOB). Note: the rare "unaligned" case is a result of the extra BBT pattern + version located in the data area instead of OOB. Also, this patch disables caching on raw reads, since we are reading without error correction. This is, obviously, prone to errors and should not be cached.

| * mtd: nand: do not scan bad blocks with NAND_BBT_NO_OOB setBrian Norris2011-09-211-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updates to our default function for creating bad block patterns have broken the "no OOB" feature. The NAND_BBT_NO_OOB option should not be set while scanning for bad blocks, but we've been passing all BBT options from nand_chip.bbt_options to the bad block scan. This causes us to hit the: BUG_ON(bd->options & NAND_BBT_NO_OOB); in create_bbt() when we scan the flash for bad blocks. Thus, while it can be legal to set NAND_BBT_NO_OOB in a custom badblock pattern descriptor (presumably with NAND_BBT_CREATE disabled?), we should not pass it through in our default function. Also, to help clarify and emphasize that the function creates bad block patterns only (not, for example, table descriptors for locating flash-based BBT), I renamed `nand_create_default_bbt_descr' to `nand_create_badblock_pattern'.

This also prevents us from falsely incrementing the table version. For example, we may have the following: Primary table, with version 0x02 Mirror table, with version 0x01 Primary table has uncorrectable ECC errors If we don't have this fix applied, then we will: Choose to read the primary table (higher version) Set mirror table version to 0x02 Read back primary table Invalidate table because of ECC errors Retry readback operation with mirror table, now version 0x02 Mirrored table reads cleanly Writeback BBT to primary table location (with "version 0x02") However, the mirrored table shouldn't have a new version number. Instead, we actually want: Choose to read the primary table (higher version) Read back primary table Invalidate table because of ECC errors Retry readback with mirror table (version 0x01) Mirrored table reads cleanly Set both tables to version 0x01 Writeback BBT to primary table location (version 0x01) Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com>
| * mtd: nand: scrub BBT on ECC errorsBrian Norris2011-09-211-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that `read_bbt()' returns ECC error codes properly, we handle those codes when checking the integrity of our flash-based BBT. The modifications can be described by this new policy: *) On any uncorrected ECC error, we invalidate the corresponding table and retry our version-checking integrity logic. *) On corrected bitflips, we mark both tables for re-writing to flash (a.k.a. scrubbing). Current integrity checks (i.e., comparing version numbers, etc.) should take care of all the cases that result in rescanning the device for bad blocks or falling back to the BBT as found in the mirror descriptor.

| * mtd: nand: report ECC errors properly when reading BBTBrian Norris2011-09-211-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of just printing a warning when encountering ECC errors, we should return a proper error status and print a more informative warning. Later, we will handle these error messages in the upper layers of the BBT scan. Note that this patch makes our check for ECC error codes a little bit more restrictive, leaving all unrecognized errors to the generic "else" clause. This shouldn't cause problems and could even be a benefit. This code is based on some findings reported by Matthieu Castet.
