* UBI: allow specifying bad PEBs limit using module parameterRichard Genoud2012-09-042-15/+27
| | | | | | | | | | | | | This patch provides the possibility to adjust the "maximum expected number of bad blocks per 1024 blocks" (max_beb_per1024) for each mtd device. The majority of NAND devices have their max_beb_per1024 equal to 20, but sometimes it's more. Now, we can adjust that via a kernel parameter: ubi.mtd=<name|num|path>[,<vid_hdr_offs>[,max_beb_per1024]] Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

* arm: sam9_l9260_defconfig: correct CONFIG_MTD_UBI_BEB_LIMITArtem Bityutskiy2012-09-041-1/+1
| | | | | | | | | | | | | | | | | | | UBI has changed the MTD_UBI_BEB_LIMIT semantics. It used to be a percent of total amount of eraseblock in the partition, and now it is the maximum amount of bad eraseblocks on the entire devise per 1024 eraseblocks. So not only the units changed, but also the meaning. Richard Genoud <richard.genoud@gmail.com> says: "I found the board: https://www.olimex.com/dev/sam9-L9260.html and the nand datasheet: http://www.rockbox.org/wiki/pub/Main/LyrePrototype/K9xxG08UXM.pdf page 11, we can see that the max_bad_bebper1024 is 25 (100 for 4096)" Thus, use "25" for sam9.

* UBI: use the whole MTD device size to get bad_peb_limitRichard Genoud2012-09-042-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On NAND flash devices, UBI reserves some physical erase blocks (PEB) for bad block handling. Today, the number of reserved PEB can only be set as a percentage of the total number of PEB in each MTD partition. For example, for a NAND flash with 128KiB PEB, 2 MTD partition of 20MiB (mtd0) and 100MiB (mtd1) and 2% reserved PEB: - the UBI device on mtd0 will have 2 PEB reserved - the UBI device on mtd1 will have 16 PEB reserved The problem with this behaviour is that NAND flash manufacturers give a minimum number of valid block (NVB) during the endurance life of the device, e.g.: Parameter Symbol Min Max Unit Notes -------------------------------------------------------------- Valid block number NVB 1004 1024 Blocks 1 From this number we can deduce the maximum number of bad PEB that a device will contain during its endurance life: a 128MiB NAND flash (1024 PEB) will not have less than 20 bad blocks during the flash endurance life. But the manufacturer doesn't tell where those bad block will appear. He doesn't say either if they will be equally disposed on the whole device (and I'm pretty sure they won't). So, according to the datasheets, we should reserve the maximum number of bad PEB for each UBI device (worst case scenario: 20 bad blocks appears on the smallest MTD partition). So this patch make UBI use the whole MTD device size to calculate the maximum bad expected eraseblocks. The Kconfig option is in per1024 blocks, thus it can have a default value of 20 which is *very* common for NAND devices.

* UBI: limit amount of reserved eraseblocks for bad PEB handlingShmulik Ladkani2012-09-042-21/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing mechanism of reserving PEBs for bad PEB handling has two flaws: - It is calculated as a percentage of good PEBs instead of total PEBs. - There's no limit on the amount of PEBs UBI reserves for future bad eraseblock handling. This patch changes the mechanism to overcome these flaws. The desired level of PEBs reserved for bad PEB handling (beb_rsvd_level) is set to the maximum expected bad eraseblocks (bad_peb_limit) minus the existing number of bad eraseblocks (bad_peb_count). The actual amount of PEBs reserved for bad PEB handling is usually set to the desired level (but in some circumstances may be lower than the desired level, e.g. when attaching to a device that has too few available PEBs to satisfy the desired level). In the case where the device has too many bad PEBs (above the expected limit), then the desired level, and the actual amount of PEBs reserved are set to zero. No PEBs will be set aside for future bad eraseblock handling - even if some PEBs are made available (e.g. by shrinking a volume). If another PEB goes bad, and there are available PEBs, then the eraseblock will be marked bad (consuming one available PEB). But if there are no available PEBs, ubi will go into readonly mode.

* UBI: introduce new bad PEB limitShmulik Ladkani2012-09-043-8/+32
| | | | | | | | | | | | | | Introduce 'ubi->bad_peb_limit', which specifies an upper limit of PEBs UBI expects to go bad. Currently, it is initialized to a fixed percentage of total PEBs in the UBI device (configurable via CONFIG_MTD_UBI_BEB_LIMIT). The 'bad_peb_limit' is intended to be used for calculating the amount of PEBs UBI needs to reserve for bad eraseblock handling. Artem: minor amendments.

* time: Move ktime_t overflow checking into timespec_valid_strictJohn Stultz2012-09-012-5/+12
| | | | | | | | | | | | | | | | | | | | | | | Andreas Bombe reported that the added ktime_t overflow checking added to timespec_valid in commit 4e8b14526ca7 ("time: Improve sanity checking of timekeeping inputs") was causing problems with X.org because it caused timeouts larger then KTIME_T to be invalid. Previously, these large timeouts would be clamped to KTIME_MAX and would never expire, which is valid. This patch splits the ktime_t overflow checking into a new timespec_valid_strict function, and converts the timekeeping codes internal checking to use this more strict function.

Rather than checking for specific bridge chip ids, just check the eDP configuration register. This saves extra aux transactions and works across DP bridge chips without requiring additional per chip id checking. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

We need to have information about crtc before setting up the encoders so I've shifted the ordering a bit. Probably we'll need a full rework akin to danvet's recent intel patchs. This patch fixes numerous issues with DP bridge chips and makes link training much more reliable. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

With r600, CB_TARGET_MASK is changed to 0xff, so we must set the number of samples of the second colorbuffer to 1 in order to pass the CS checker. The DRM version is bumped, because RESOLVE_BOX is always rejected without this fix on r600.

Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).
