But the ufs host sends SSU to wlun during its runtime-suspend.

clocksource watchdog runs every 500ms, which creates some OS noise.
As the clocksource wreckage (especially for those that has per-cpu

HI Dmitry:
So data->ops->initialize(client) essentially performs reset of the
controller (we may want to rename it even) and as far as I understand
you would want to avoid resetting the controller on newer devices,
right?
-> YES
My question is how behavior of older devices differ from the new on

Why not utilize VMCB_CR?
Yes, such user includes libfabric (https://ofiwg.github.io/libfabric/) . which
uses hugetlb pages.

This returns back non-coherent (previously known as NON_COHERENT)

This adds support for new noncontiguous DMA API, which
requires allocators to have two execution branches: one
for the current API, and one for the new one.

This patch lets user-space to request a non-coherent memory

struct v4l2_create_buffers has seven 4-byte reserved areas,

This moves cache hints handling from videobuf2 core down
to allocators level, because allocators do the sync/flush
caches eventually and may take better decisions. Besides,
allocators already decide whether cache sync/flush should
be done or can be skipped. This patch moves the scattered

By setting or clearing V4L2_FLAG_MEMORY_NON_COHERENT flag
user-space should be able to hint vb2 that either a non-coherent

allocation.
The patch set also adds a corresponding capability flag:
fill_buf_caps() reports V4L2_BUF_CAP_SUPPO
V4L2 is not the perfect place to manage vb2 buffer cache hints.
It works for V4L2 users, but there are backends that use vb2 core
and don't use V4L2. Factor buffer cache hints init and call it
when we allocate vb2 buffer.

It would be less error prone if the default cache hints value
(we kzalloc() structs, so it's zeroed out by default) would be
to "always sync/flush" caches. Inverse and rename cache hints
flags.

With new DMA API we need an extension of videobuf2 API. Previously,
videobuf2 core would set non-coherent DMA bit in vb2 queue dma_attr
(if user-space would pass a corresponding memory hint); vb2 core
then would pass the vb2 queue dma_attrs to the vb2 allocators.
vb2 allocator would use queue's dma
Hello,
RFC
The series adds support for new noncontiguous DMA API [0] and
adds V4L2_FLAG_MEMORY_NON_COHERENT UAPI. This is similar to previous
V4L2_FLAG_MEMORY_NON_CONSISTENT (which was renamed), but the patch set
goes a bit further this time and also does some videobuf2 API
