This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

There are two different types of booting firmware on Alphas: SRM,
|
|
which is command line driven, and ARC, which uses menus and arrow
|
|
keys. Details about the Linux/Alpha booting process are contained in
|
|
the Linux/Alpha FAQ, accessible on the WWW from
|
|
<http://www.alphalinux.org/>.
|
|
|
|
The usual way to load Linux on an Alpha machine is to use MILO
|
|
(a bootloader that lets you pass command line parameters to the
|
|
kernel just like lilo does for the x86 architecture) which can be
|
|
loaded either from ARC or can be installed directly as a permanent
|
|
firmware replacement from floppy (which requires changing a certain
|
|
jumper on the motherboard). If you want to do either of these, say N
|
|
here. If MILO doesn't work on your system (true for Jensen
|
|
motherboards), you can bypass it altogether and boot Linux directly
|
|
from an SRM console; say Y here in order to do that. Note that you
|
|
won't be able to boot from an IDE disk using SRM.
|
|
|
|
If unsure, say N.

This enables support for systems with more than one CPU. If you have
|
|
a system with only one CPU, like most personal computers, say N. If
|
|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If
|
|
you say Y here, the kernel will run on many, but not all,
|
|
singleprocessor machines. On a singleprocessor machine, the kernel
|
|
will run faster if you say N here.

Process creation and other aspects of virtual memory management can

be streamlined if we restrict the kernel to one PGD for all vmalloc
|
|
allocations. This equates to about 8GB.
|
|
|
|
Under normal circumstances, this is so far and above what is needed
|
|
as to be laughable. However, there are certain applications (such
|
|
as benchmark-grade in-kernel web serving) that can make use of as
|
|
much vmalloc space as is available.

Say N unless you know you need gobs and gobs of vmalloc space.

---help---

This option allows the default printing mode to be set, and then

|
possibly overridden by a boot command argument.
|
|
|
|
For example, if one wanted the option of printing verbose
|
|
machine checks, but wanted the default to be as if verbose
|
|
machine check printing was turned off, then one would choose
|
|
the printing mode to be 0. Then, upon reboot, one could add
|
|
the boot command line "verbose_mcheck=1" to get the normal
|
|
verbose machine check printing, or "verbose_mcheck=2" to get
|
|
the maximum information available.
|
|
|
|
Take the default (1) unless you want more control or more info.

If you enable this option, a subdirectory inside /proc called

/proc/srm_environment will give you access to the all important

SRM environment variables (those which have a name) and also

|
to all others (by their internal number).
|

SRM is something like a BIOS for Alpha machines. There are some
|
|
other such BIOSes, like AlphaBIOS, which this driver cannot
|
|
support (hey, that's not SRM!).
|
|
|
|
Despite the fact that this driver doesn't work on all Alphas (but
|
|
only on those which have SRM as their firmware), it's save to
|
|
build it even if your particular machine doesn't know about SRM
|
|
(or if you intend to compile a generic kernel). It will simply
|
|
not create those subdirectory in /proc (and give you some warning,
|
|
of course).
|
|
|
|
This driver is also available as a module and will be called
|
|
srm_env then.
