the end of the loop there is a potiential for err to be unassigned

Hello,
I tried to debug this a bit.
It seems that the XHCI ring has two segments. For me, the first has DMA
address 0xfffb9000 and the second has fffb8000.
The TRBs on the first segment are used successfully up to address
fffb9fd0 (which seems to be 253 TRBs?).

During load balance, LBF_SOME_PINNED will bet set if any candidate task
cannot be detached due to CPU affinity constraints. This can result in
setting env->sd->parent->sgc->group_imbalance, which can lead to a group
being classified as group_imbalanced (rather than an
When triggering an active load balance, sd->nr_balance_failed is set to
such a value that any further can_migrate_task() using said sd will ignore
the output of task_hot().
This behaviour makes sense, as active load balance intentionally preempts a
rq's running task to migrate it right away, but t
Hi folks,
I split up the extra misfit patches from v3 as I'm still playing around with
those following Vincent's comments. In the meantime, I believe the first few
patches of the series can still be considered as standalone.
o Patch 1 prevents pcpu kworkers from causing group_imbalanced
o Patch 2
During load-balance, groups classified as group_misfit_task are filtered
out if they do not pass
group_smaller_max_cpu_capacity(, );
which itself employs fits_capacity() to compare the sgc->max_capacity of
both groups.
Due to the underlying margin, fits_capacity(X, 1024) will return false for

Hi Linus,
Things have settled down in time for Easter, a random smattering of
small fixes across a few drivers. I'm guessing though there might be
some i915 and misc fixes out there I haven't gotten yet, but since
today is a public holiday here, I'm sending this early so I can have
the day off, I'
Both Android and Chrome OS really want this feature; For Container-Optimized
OS, we have customers
interested in the defense too.
Thank you very much.

lock_stat + mmm_donut[1] say that this reduces contention on mm_lock

The DTPM framework provides a generic API to register devices which
power capable. The devices may be compiled as modules while the
framework is not.
Export the necessary API to let the drivers register themselves.

The DTPM framework is built on top of the powercap framework as a new
controller to act on the power of the devices. The approach is to
provide an unified API to do power limitation on devices which are
capable of that with different techniques.
In addition, the DTPM framework allows to create a h
Currently the power consumption is based on the current OPP power
assuming the entire performance domain is fully loaded.
That gives very gross power estimation and we can do much better by
using the load to scale the power consumption.
Use the utilization to normalize and scale the power usage o
Previously, the continue implementation in shmem_mcopy_atomic_pte was
incorrect for two main reasons:
- It didn't correctly skip some sections of code which make sense for
newly allocated pages, but absolutely don't make sense for
pre-existing page cache pages.
- Because shmem_mcopy_continue_
The dtpm table is an array of pointers, that forces the user of the
table to define initdata along with the declaration of the table
entry. It is more efficient to create an array of dtpm structure, so
the declaration of the table entry can be done by initializing the
different fields.

The dtpm framework provides an API to allocate a dtpm node. However
when a backend dtpm driver needs to allocate a dtpm node it must
define its own structure and store the pointer of this structure in
the private field of the dtpm structure.
It is more elegant to use the container_of macro and add
In order to increase the self-encapsulation of the dtpm generic code,
the following changes are adding a power update ops to the dtpm

The power update function does compute the power characteri
