Add namespace-helper functions to access per-namespace parameters
and variables. Create per-namespace control socket for out-of-the-

Possibly-relevant info:

- KMS, Xserver 1.12.3, driver 6.14.6-28 (trunk current as of today),
Mesa 8.0.4, libdrm 2.4.37

I would like to report an issue in the nouveau driver, but don't know
who to report it to.

Allow to dynamically switch between tick and virtual based cputime accounting.
This way we can provide a kind of "on-demand" virtual based cputime
accounting. In this mode, the kernel will rely on the user hooks
subsystem to dynamically hook on kernel boundaries.
This is in preparation for beeing
Create a new subsystem that probes on kernel boundaries
to keep track of the transitions between level contexts
with two basic initial contexts: user or kernel.
This is an abstraction of some RCU code that use such tracking
to implement its userspace extended quiescent state.
We need to pull this
We may soon be able to run both at the same time. But we need
to rework a bit the irq finegrained accounting before that.
Just do a mutual exclusion for now.

If we want to stop the tick further idle, we need to be
able to account the cputime without using the tick.
Virtual based cputime accounting solves that problem by
hooking into kernel/user boundaries.
However implementing CONFIG_VIRT_CPU_ACCOUNTING requires
to set low level hooks and involves mor
account_system_vtime() can be called from random places:
hard/softirq entry/exit, kvm guest entry/exit, and even
context switches on powerpc.
Rename it to the even more generic account_vtime() name,
this reflect well that we are in a random place in the
kernel where we have either system, idle or
Hi,
Changes since v2 (https://lwn.net/Articles/509575/) are only about
converting the "code domain tracking" naming to "context tracking"
as per Ingo's suggestion. And the result indeed looks much better.
