[media] media: Sanitise the reserved fields of the G_TOPOLOGY IOCTL arguments

2016-03-03T21:10:53+00:00

The argument structs are used in arrays for G_TOPOLOGY IOCTL. The
arguments themselves do not need to be aligned to a power of two, but
aligning them up to the largest basic type alignment (u64) on common ABIs
is a good thing to do.

The patch changes the size of the reserved fields to 5 or 6 u32's and
aligns the size of the struct to 8 bytes so we do no longer depend on the
compiler to perform the alignment.

While at it, add __attribute__ ((packed)) to these structs as well.

[media] media.h: postpone connectors entities

2016-03-03T17:52:51+00:00

The representation of external connections got some heated
discussions recently. As we're too close to the merge window,
let's not set those entities into a stone.

[media] media.h: use hex values for range offsets, move connectors base up.

2016-03-03T08:56:33+00:00

Make the base offset hexadecimal to simplify debugging since the base
addresses are hex too.

The offsets for connectors is also changed to start after the 'reserved'
range 0x10000-0x2ffff.

nfit: update address range scrub commands to the acpi 6.1 format

2016-02-24T01:17:20+00:00

The original format of these commands from the "NVDIMM DSM Interface
Example" [1] are superseded by the ACPI 6.1 definition of the "NVDIMM Root
Device _DSMs" [2].

[1]: http://pmem.io/documents/NVDIMM_DSM_Interface_Example.pdf
[2]: http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf
     "9.20.7 NVDIMM Root Device _DSMs"

Changes include:
1/ New 'restart' fields in ars_status, unfortunately these are
   implemented in the middle of the existing definition so this change
   is not backwards compatible.  The expectation is that shipping
   platforms will only ever support the ACPI 6.1 definition.

2/ New status values for ars_start ('busy') and ars_status ('overflow').

[media] media.h: get rid of MEDIA_ENT_F_CONN_TEST

2016-02-16T11:15:23+00:00

Defining it as a connector was a bad idea. Remove it while it is
not too late.

[media] [for,v4.5] media.h: increase the spacing between function ranges

2016-02-16T11:07:16+00:00

Each function range is quite narrow and especially for connectors this
will pose a problem. Increase the function ranges while we still can and
move the connector range to the end so that range is practically limitless.

Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

2016-02-01T23:21:20+00:00

Pull libnvdimm fixes from Dan Williams:
 "1/ Fixes to the libnvdimm 'pfn' device that establishes a reserved
     area for storing a struct page array.

  2/ Fixes for dax operations on a raw block device to prevent pagecache
     collisions with dax mappings.

  3/ A fix for pfn_t usage in vm_insert_mixed that lead to a null
     pointer de-reference.

  These have received build success notification from the kbuild robot
  across 153 configs and pass the latest ndctl tests"

* 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
  phys_to_pfn_t: use phys_addr_t
  mm: fix pfn_t to page conversion in vm_insert_mixed
  block: use DAX for partition table reads
  block: revert runtime dax control of the raw block device
  fs, block: force direct-I/O for dax-enabled block devices
  devm_memremap_pages: fix vmem_altmap lifetime + alignment handling
  libnvdimm, pfn: fix restoring memmap location
  libnvdimm: fix mode determination for e820 devices

block: revert runtime dax control of the raw block device

2016-01-30T21:35:31+00:00

Dynamically enabling DAX requires that the page cache first be flushed
and invalidated.  This must occur atomically with the change of DAX mode
otherwise we confuse the fsync/msync tracking and violate data
durability guarantees.  Eliminate the possibilty of DAX-disabled to
DAX-enabled transitions for now and revisit this for the next cycle.
