ASoC: Intel: Skylake: Automatic DMIC format configuration according to information from NHLT

2020-12-02T07:49:57+00:00

commit 2d744ecf2b98405723a2138a547e5c75009bc4e5 upstream.

Automatically choose DMIC pipeline format configuration depending on
information included in NHLT.
Change the access rights of appropriate kcontrols to read-only in order
to prevent user interference.

ASoC: Intel: Multiple I/O PCM format support for pipe

2020-12-02T07:49:57+00:00

commit 1b450791d517d4d6666ab9ab6d9a20c8819e3572 upstream.

For pipes supporting multiple input/output formats, kcontrol is
created and selection of pipe input and output configuration
is done based on control set.

If more than one configuration is supported, then this patch
allows user to select configuration of choice
using amixer settings.

wireless: Use linux/stddef.h instead of stddef.h

2020-12-02T07:49:45+00:00

commit 1b9ae0c92925ac40489be526d67d0010d0724ce0 upstream.

When compiling inside the kernel include linux/stddef.h instead of
stddef.h. When I compile this header file in backports for power PC I
run into a conflict with ptrdiff_t. I was unable to reproduce this in
mainline kernel. I still would like to fix this problem in the kernel.

NFSv4.2: support EXCHGID4_FLAG_SUPP_FENCE_OPS 4.2 EXCHANGE_ID flag

commit 8c39076c276be0b31982e44654e2c2357473258a upstream.

RFC 7862 introduced a new flag that either client or server is
allowed to set: EXCHGID4_FLAG_SUPP_FENCE_OPS.

Client needs to update its bitmask to allow for this flag value.

btrfs: tree-checker: fix false alert caused by legacy btrfs root item

2020-11-05T10:43:27+00:00

commit 1465af12e254a68706e110846f59cf0f09683184 upstream.

Commit 259ee7754b67 ("btrfs: tree-checker: Add ROOT_ITEM check")
introduced btrfs root item size check, however btrfs root item has two
versions, the legacy one which just ends before generation_v2 member, is
smaller than current btrfs root item size.

This caused btrfs kernel to reject valid but old tree root leaves.

Fix this problem by also allowing legacy root item, since kernel can
already handle them pretty well and upgrade to newer root item format
when needed.

media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:43:15+00:00

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ]

The default RGB quantization range for BT.2020 is full range (just as for
all the other RGB pixel encodings), not limited range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation
accordingly.

Also mention that HSV is always full range and cannot be limited range.

When RGB BT2020 was introduced in V4L2 it was not clear whether it should
be limited or full range, but full range is the right (and consistent)
choice.

perf: correct SNOOPX field offset

[ Upstream commit f3d301c1f2f5676465cdf3259737ea19cc82731f ]

perf_event.h has macros that define the field offsets in the
data_src bitmask in perf records. The SNOOPX and REMOTE offsets
were both 37. These are distinct fields, and the bitfield layout
in perf_mem_data_src confirms that SNOOPX should be at offset 38.

KVM: MIPS: Change the definition of kvm type

2020-09-23T10:40:38+00:00

[ Upstream commit 15e9e35cd1dec2bc138464de6bf8ef828df19235 ]

MIPS defines two kvm types:

 #define KVM_VM_MIPS_TE          0
 #define KVM_VM_MIPS_VZ          1

In Documentation/virt/kvm/api.rst it is said that "You probably want to
use 0 as machine type", which implies that type 0 be the "automatic" or
"default" type. And, in user-space libvirt use the null-machine (with
type 0) to detect the kvm capability, which returns "KVM not supported"
on a VZ platform.

I try to fix it in QEMU but it is ugly:
https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg05629.html

And Thomas Huth suggests me to change the definition of kvm type:
https://lists.nongnu.org/archive/html/qemu-devel/2020-09/msg03281.html

So I define like this:

 #define KVM_VM_MIPS_AUTO        0
 #define KVM_VM_MIPS_VZ          1
 #define KVM_VM_MIPS_TE          2

Since VZ and TE cannot co-exists, using type 0 on a TE platform will
still return success (so old user-space tools have no problems on new
kernels); the advantage is that using type 0 on a VZ platform will not
return failure. So, the only problem is "new user-space tools use type
2 on old kernels", but if we treat this as a kernel bug, we can backport
this patch to old stable kernels.
