| * | mtd: extend plat_nand for (read|write)_bufAlexander Clouter2009-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds (write|read)_buf callbacks to plat_nand. The NAND on the TS-7800 provisioned by the FPGA allows readw() and readl() to be used which gives a 2.5x speed up. To be able to use this from the plat_nand driver a hook for read_buf (and also write_buf whilst we are in there) need to be made available. This patch adds the hook.

| * | mtd: davinci_nand: cmdlinepart uses MTD IDsDavid Brownell2009-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove some legacy code from the davinci_nand driver, which made cmdlinepart ignore the the MTD ID passed to it. Boards can have multiple NAND chips, and some do (like the DM357 EVM), so this dated hack is undesirable. Correct labels are like "davinci_nand.0" (for chipselect 0).

This is limited to small-page flash for now; there are some page layout issues for large page chips. Note that most boards using this engine (like the DM355 EVM) include 2GiB large page chips.

ATM, only -EIO errors trigger 1., other errors trigger 2. The idea is that if we know we encountered an I/O error, do 1. Otherwise, we do not know how to react, and do 2., just in case. E.g., if the underlying driver became crazy because of a bug, we do not want to harm any data, and switch to R/O mode. This patch does 2 things: 1. Makes sure reads from the source PEB always cause 1. This is more consistent with other reads which come from the upper layers and never cause R/O. 2. Teaches UBI to do 1. also on -EBADMSG, UBI_IO_BAD_VID_HDR, -ENOMEM, and -ETIMEOUT. But this is only when reading the target PEB. This preblems were hunted by Adrian Hunter.

Clients also can request "added" events on all volumes that existed before client subscribed to the notifications. If we use notifications instead of calling functions like 'ubi_gluebi_xxx()', we can make the MTD emulation layer to be more flexible: build it as a separate module and load/unload it on demand.

ATM UBI switches to R/O mode when the WL worker fails to read the source PEB. This means that the upper layers (e.g., UBIFS) has no chances to unmap the erroneous PEB and fix the error. This patch changes this behaviour and makes UBI put PEBs like this into a separate RB-tree, thus preventing the WL worker from hitting the same read errors again and again. But there is a 10% limit on a maximum amount of PEBs like this. If there are too much of them, UBI switches to R/O mode. Additionally, this patch teaches UBI not to panic and switch to R/O mode if after a PEB has been copied, the target LEB cannot be read back. Instead, now UBI cancels the operation and schedules the target PEB for torturing. The error paths has been tested by ingecting errors into 'ubi_eba_copy_leb()'.

This is not fatal at all, it may just result at sligtly worse performace for a short period of time, just because the thread will be woken up when real I/O on the UBI starts. Anywey, the issue is the race condition between 'ubi_attach_mtd_dev()' and 'ubi_thread()'.

Suppose there are 2 tasks - A and B. Task A is the wear-levelling working ('wear_leveling_worker()'). It is reading the VID header to find which LEB this PEB belongs to. Say, task A is reading header of PEB X. Suppose PEB X is unmapped, and has no VID header. Task B is trying to write to PEB X. Task A: in 'ubi_io_read_vid_hdr()': reads the VID header from PEB X. The read data contain all 0xFF bytes. Task B: writes VID header and some data to PEB X Task A: assumes PEB X is empty, calls 'paranoid_check_all_ff()', which fails. The solution for this problem is to make 'paranoid_check_all_ff()' re-read the VID header, re-check it, and only if it is not there, check the rest.

| * | | UBI: remove redundant mutexArtem Bityutskiy2009-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @mult_mutex does not serve any purpose. We already have @volumes_mutex and it is enough. The @volume mutex is pushed down to the 'ubi_rename_volumes()', because we want first to open all volumes in the exclusive mode, and then lock the mutex, just like all other ioctl's (remove, re-size, etc) do.
