| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All UBI needs is to make sure we stacktraces when UBI debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. And the current Kconfig line we have: select KALLSYMS_ALL if KALLSYMS && DEBUG_KERNEL is just too complex to be sane and right. But this "if" part there is needed to prevent "unmet direct dependency" warnings, because KALLSYMS_ALL depends on KALLSYMS and DEBUG_KERNEL, so we cannot just select KALLSYMS_ALL. Anyway, this feels messy, and we do not seem to really need KALLSYMS_ALL, so select KALLSYMS instead.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

We are killing this buffer because we are going to switch to dynamic debugging control, just like in UBIFS, which means that CONFIG_MTD_UBI_DEBUG_PARANOID will be removed. In this case we'd end up always allocating 'ubi->dbg_peb_buf', which is rather large (128KiB or more), and this would be wasteful. Thus, we are just killing it.

And the need for this arises because we want to change to dynamic debugging control instead of compile-time control, i.e., we are going to kill the CONFIG_MTD_UBI_DEBUG_PARANOID Kconfig option, which would mean that 'ubi->dbg_peb_buf' is always allocated, which would be wasteful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the read operation fails, UBI tries to re-read several times in a hope that one of the subsequent reads may succeed. However, currently UBI re-reads only if MTD failed to read all data, but does not re-reads if all the data were read, but with an integrity error (-EBADMSB). This patch makes UBI to always re-try reading. This should be useful for reading NAND pages with unstable bits - re-reading may help to get correct data.

Use slab cache to reduce memory consumption for these 48-byte objects, because currently used 'kmalloc()' ends up allocating 64 bytes per object, instead of 48.

The idea is to fix the following possible situation: 1. The buffer contains data from previous operation, e.g., read from another PEB previously. The data looks like expected, e.g., if we just do not read anything and return - the caller would not notice this. E.g., if we are reading a VID header, the buffer may contain a valid VID header from another PEB. 2. The driver is buggy and returns use success or -EBADMSG or -EUCLEAN, but it does not actually put any data to the buffer. This may confuse UBI or upper layers - they may think the buffer contains valid data while in fact it is just old data. Thus, try to reveal such buggy MTD drivers with simple debugging code which fills the read buffer with 0x12 constant. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

If errors happen during multibock erase then the specification recommends to run multiblock erase verify command with maximum timeout 10ms (see specs. for KFM4G16Q2A and KFN8G16Q2A). For the most common non-error case we wait 100us in udelay polling loop. In case of timeout the interrupt mode is used to wait for the command end.

So as to have in sync with ecc layout throughout; i.e. x-loader, u-boot and kernel. This enables to flash x-loader, u-boot, kernel, FS images from kernel itself and compatiable with other tools. This patch does not enables this feature by default and need to pass from board file to enable for any board.
