I use a Logitech wireless keyboard (with a Unifying receiver) and it
keeps working fine even with `auto`.
That is, everything is OK if the receiver is plugged before

But as Russell says, even if we don't have the empty callback, we still
create the problem shown
This make sure that we try to allocate hugepages from local node if
allowed by mempolicy. If we can't, we fallback to small page allocation
based on mempolicy. This is based on the observation that allocating pages
on local node is more beneficial than allocating hugepages on remote
node.

When converting int values, perf first extractes it to a ulonglong, then
feeds it to babeltrace as a signed value. For negative 32 bit values
(for example, return values of failed syscalls), the extracted data
should be something like 0xfffe (-2). It becomes a large int64
value. Babeltrace
Some parameters of syscall tracepoints named as 'nr', 'event', etc.
When dealing with them, perf convert to ctf meets some problems:
1. If a parameter with name 'nr', it duplicate syscall's
common field 'nr'. One example syscall is io_submit().
2. If a parameter with name 'event', it is

It might remove an #if but it doesn't really help.
All it means is that anyone reading the code has to hunt for
the definition before proceeding.
Some comment about what (and why) the extra code is needed
might help.

There is no use-case where it would be useful for drivers not to
implement this function and the transitional plane helpers already
require drivers to provide an implementation.

This series converts the Tegra DRM driver to atomic mode-setting. The

The first patch adds a new function to the clk API that allows checking

When VF multicast promiscuous mode is enabled, all multicast packets are

After enabling multicast promiscuous mode from the host, we can use over 30

This callback can be used instead of the legacy ->mode_fixup() and is
passed the CRTC and connector states. It can thus use these states to
validate the modeset and cache values in the state to be used during
the actual modeset.

In order to prevent drivers from having to perform the same checks over
and over again, add an optional ->atomic_disable callback which the core
calls under the right circumstances.

When disabling the display controller, stop it and wait for it to become
idle. Doing so ensures that no further accesses to the framebuffer occur
and the buffers can be safely unmapped or freed.

Previously output drivers would all stop the display controller in their

The DRM core should take care of disabling all unneeded planes, so there
is no need to do this explicitly.

The output layer was initially designed to help reduce the amount of
code duplicated in output drivers. An unfortunate side-effect of that
was that it turned into a midlayer and it became difficult to make the
output drivers work without bending over backwards to fit into
