2017-11-13IB/hfi1: Fix a wrapping test to insure the correct timeoutMike Marciniszyn3-5/+5
The "2 * UINT_MAX" statement: if ((u64)(ts - cce->timestamp) > 2 * UINT_MAX) { is equivalent to: if ((u64)(ts - cce->timestamp) > UINT_MAX - 1) { This results in a premature timeout of the cong log entry. Fix by using unsigned 64 bit integers, removing casts, and using an algebraic equivalent test to avoid the "2 * UINT_MAX" issue. Also make use of kernel API to get nanoseconds instead of open coding.

2017-11-13mtd: sharpslpart: Add sharpslpart partition parserAndrea Adami3-0/+407
The Sharp SL Series (Zaurus) PXA handhelds have 16/64/128M of NAND flash and share the same layout of the first 7M partition, managed by Sharp FTL. GPL 2.4 sources: http://support.ezaurus.com/developer/source/source_dl.asp The purpose of this self-contained patch is to add a common parser and remove the hardcoded sizes in the board files (these devices are not yet converted to devicetree). Users will have benefits because the mtdparts= tag will not be necessary anymore and they will be free to repartition the little sized flash. The obsolete bootloader can not pass the partitioning info to modern kernels anymore so it has to be read from flash at known logical addresses. (see http://www.h5.dion.ne.jp/~rimemoon/zaurus/memo_006.htm ) In kernel, under arch/arm/mach-pxa we have already 8 machines: MACH_POODLE, MACH_CORGI, MACH_SHEPERD, MACH_HUSKY, MACH_AKITA, MACH_SPITZ, MACH_BORZOI, MACH_TOSA. Lost after the 2.4 vendor kernel are MACH_BOXER and MACH_TERRIER. Almost every model has different factory partitioning: add to this the units can be repartitioned by users with userspace tools (nandlogical) and installers for popular (back then) linux distributions. The Parameter Area in the first (boot) partition extends from 0x00040000 to 0x0007bfff (176k) and contains two copies of the partition table: ... 0x00060000: Partition Info1 16k 0x00064000: Partition Info2 16k 0x00668000: Model 16k ... The first 7M partition is managed by the Sharp FTL reserving 5% + 1 blocks for wear-leveling: some blocks are remapped and one layer of translation (logical to physical) is necessary. There isn't much documentation about this FTL in the 2.4 sources, just the MTD methods for reading and writing using logical addresses and the block management (wear-leveling, use counter). It seems this FTL was tailored with 16KiB eraesize in mind so to fit one param block exactly, to have two copies of the partition table on two blocks. Later pxa27x devices have same size but 128KiB erasesize and less blocks (56 vs. 448) but the same schema was adopted, even if the two tables are now in the same eraseblock. For the purpose of the MTD parser only the read part of the code was taken. The NAND drivers that can use this parser are sharpsl.c and tmio_nand.c.

2017-11-13mtd: Add sanity checks in mtd_write/read_oob()Boris Brezillon1-0/+44
Unlike what's done in mtd_read/write(), there are no checks to make sure the parameters passed to mtd_read/write_oob() are consistent, which forces implementers of ->_read/write_oob() to do it, which in turn leads to code duplication and possibly errors in the logic.

2017-11-13mtd: implement mtd_get_unmapped_area() using the point methodNicolas Pitre1-5/+12
The mtd->_point method is a superset of mtd->_get_unmapped_area. Especially in the NOR flash case, the point method ensures the flash memory is in array (data) mode and that it will stay that way which is precisely what callers of mtd_get_unmapped_area() would expect.

low frequency mode. Extended testing has shown that the imx ahci driver sometimes requires more than the 100 attempts currently alotted in the driver to perform a successful temperature reading when running at minimum (throttled) CPU frequency. Debugging suggests that the read cycle can take 160 attempts (which given that the driver averages 80 readings from the ADC equates to one failure on each read). Increase the attempt limit to 200 in order to greatly reduce the likelihood of the driver failing to perform a temperature reading, especially at low CPU frequency.

2017-11-13drm/i915: There is only one fault register from GEN8 onwardsMichel Thierry3-18/+49
Until Haswell/Baytrail, the hardware used to have a per engine fault register (e.g. 0x4094 - render fault register, 0x4194 - media fault register and so on). But since Broadwell, all these registers were combined into a singe one and the engine id stored in bits 14:12. Not only we should not been reading (and writing to) registers that do not exist, in platforms with VCS2 (SKL), the address that would belong this engine (0x4494, VCS2_HW = 4) is already assigned to other register. v2: use less controversial function names (Chris). v3: make non-exported functions static, remove now obsolete check for engine presence before posting_read (Chris).

2017-11-13drm/i915: Clear per-engine fault register as early as possibleMichel Thierry2-2/+2
From gen6, the hardware tracks address lookup failures and we should clear those registers upon startup to prevent false positives. However, this was happening before we have the engines defined (intel_uncore_init()) and the for_each_engine loop was just a nop. The earliest we can call this is inside intel_engines_init_mmio().

2017-11-13IB/mlx5: Assign send CQ and recv CQ of UMR QPMajd Dibbiny1-0/+2
The UMR's QP is created by calling mlx5_ib_create_qp directly, and therefore the send CQ and the recv CQ on the ibqp weren't assigned. Assign them right after calling the mlx5_ib_create_qp to assure that any access to those pointers will work as expected and won't crash the system as might happen as part of reset flow.
