NAND can experience a large number of\nbitflips (beyond the recommended correctability capacity) due to drifts\nin the voltage threshold (Vt). These bitflips can cause ECC errors to\noccur well within the expected lifetime of the flash. To account for\nthis, some manufacturers provide a mechanism for shifting the Vt\nthreshold after a corrupted read.\n\nThe generic pattern seems to be that a particular flash has N read retry\nmodes (where N \u003d 0, traditionally), and after an ECC failure, the host\nshould reconfigure the flash to use the next available mode, then retry\nthe read operation. This process repeats until all bitfips can be\ncorrected or until the host has tried all available retry modes.\n\nThis patch adds the infrastructure support for a\nvendor-specific/flash-specific callback, used for setting the read-retry\nmode (i.e., voltage threshold).\n\nFor now, this patch always returns the flash to mode 0 (the default\nmode) after a successful read-retry, according to the flowchart found in\nMicron\u0027s datasheets. This may need to change in the future if it is\ndetermined that eventually, mode 0 is insufficient for the majority of\nthe flash cells (and so for performance reasons, we should leave the\nflash in mode 1, 2, etc.).\n\nSigned-off-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nAcked-by: Huang Shijie \u003cb32955@freescale.com\u003e\n" }, { "commit": "6f0065b0124bef5e66869ec0b813d251797be439", "tree": "ef982ac50c08b9950396f106baf5abe968d33f74", "parents": [ "b72f3dfb8ccf7e39b9434f548c1c98aa45c11426" ], "author": { "name": "Brian Norris", "email": "computersforpeace@gmail.com", "time": "Tue Dec 03 12:02:20 2013 -0800" }, "committer": { "name": "Brian Norris", "email": "computersforpeace@gmail.com", "time": "Mon Jan 13 23:12:53 2014 -0800" }, "message": "mtd: nand: add ONFI vendor block for Micron\n\nSigned-off-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nAcked-by: Huang Shijie \u003cb32955@freescale.com\u003e\n" }, { "commit": "6e14a61d412eb87ef7bdcec8b08a95bead771a78", "tree": "485dff0b5de49c083b1d04c81881c99a45a71063", "parents": [ "cf3b2b1e24998ba67ca6defa71899bee2432046f" ], "author": { "name": "Axel Lin", "email": "axel.lin@ingics.com", "time": "Sun Dec 01 19:01:06 2013 +0800" }, "committer": { "name": "Brian Norris", "email": "computersforpeace@gmail.com", "time": "Fri Jan 03 11:22:22 2014 -0800" }, "message": "mtd: make register_mtd_parser return void\n\nregister_mtd_parser never fails;

Previous functionality\nis preserved when passing UBI_ALL for both values. The locations where ubi_wl_flush\nwere called are appropriately changed: ubi_leb_erase only flushes for the\nerased LEB, and ubi_create_volume forces only flushing for its volume id.\nExternal code can call this new feature via the new function ubi_flush() added\nto kapi.c, which simply passes through to ubi_wl_flush().\n\nThis was tested by disabling the call to do_work in ubi thread, which results\nin the work queue remaining unless explicitly called to remove. UBIFS was\nchanged to call ubifs_leb_change 50 times for four different LEBs. Then the\nnew function was called to clear the queue: passing wrong volume ids / lnum,\ncorrect ones, and finally UBI_ALL for both to ensure it was finally all\ncleard. The work queue was dumped each time and the selective removal\nof the particular LEB numbers was observed. Extra checks were enabled and\nubifs\u0027s integck was also run.
