Kernel driver f71805f
=====================
Supported chips:
* Fintek F71805F/FG
Prefix: 'f71805f'
Addresses scanned: none, address read from Super I/O config space
Datasheet: Provided by Fintek on request
Author: Jean Delvare <khali@linux-fr.org>
Thanks to Denis Kieft from Barracuda Networks for the donation of a
test system (custom Jetway K8M8MS motherboard, with CPU and RAM) and
for providing initial documentation.
Thanks to Kris Chen from Fintek for answering technical questions and
providing additional documentation.
Thanks to Chris Lin from Jetway for providing wiring schematics and
anwsering technical questions.
Description
-----------
The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
capabilities. It can monitor up to 9 voltages (counting its own power
source), 3 fans and 3 temperature sensors.
This chip also has fan controlling features, using either DC or PWM, in
three different modes (one manual, two automatic). The driver doesn't
support these features yet.
The driver assumes that no more than one chip is present, which seems
reasonable.
Voltage Monitoring
------------------
Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
range is thus from 0 to 2.040 V. Voltage values outside of this range
need external resistors. An exception is in0, which is used to monitor
the chip's own power source (+3.3V), and is divided internally by a
factor 2.
The two LSB of the voltage limit registers are not used (always 0), so
you can only set the limits in steps of 32 mV (before scaling).
The wirings and resistor values suggested by Fintek are as follow:
pin expected
name use R1 R2 divider raw val.
in0 VCC VCC3.3V int. int. 2.00 1.65 V
in1 VIN1 VTT1.2V 10K - 1.00 1.20 V
in2 VIN2 VRAM 100K 100K 2.00 ~1.25 V (1)

in4 VIN4 VCC5V 200K 47K 5.25 0.95 V
in5 VIN5 +12V 200K 20K 11.00 1.05 V
in6 VIN6 VCC1.5V 10K - 1.00 1.50 V
in7 VIN7 VCORE 10K - 1.00 ~1.40 V (1)
in8 VIN8 VSB5V 200K 47K 1.00 0.95 V
(1) Depends on your hardware setup.
(2) Obviously not correct, swapping R1 and R2 would make more sense.
These values can be used as hints at best, as motherboard manufacturers
are free to use a completely different setup. As a matter of fact, the
Jetway K8M8MS uses a significantly different setup. You will have to
find out documentation about your own motherboard, and edit sensors.conf
accordingly.
Each voltage measured has associated low and high limits, each of which
triggers an alarm when crossed.
Fan Monitoring
--------------
Fan rotation speeds are reported as 12-bit values from a gated clock
signal. Speeds down to 366 RPM can be measured. There is no theoretical
high limit, but values over 6000 RPM seem to cause problem. The effective
resolution is much lower than you would expect, the step between different
register values being 10 rather than 1.
The chip assumes 2 pulse-per-revolution fans.
An alarm is triggered if the rotation speed drops below a programmable
limit or is too low to be measured.
Temperature Monitoring
----------------------
Temperatures are reported in degrees Celsius. Each temperature measured
has a high limit, those crossing triggers an alarm. There is an associated
hysteresis value, below which the temperature has to drop before the
alarm is cleared.
All temperature channels are external, there is no embedded temperature
sensor. Each channel can be used for connecting either a thermal diode
or a thermistor. The driver reports the currently selected mode, but
doesn't allow changing it. In theory, the BIOS should have configured
everything properly.

1) Overview
-----------
Most legacy operating system kernels support an abstraction of threads
as multiple execution contexts within a process. These kernels provide
special resources and mechanisms to maintain these "threads". The Linux
kernel, in a clever and simple manner, does not make distinction
between processes and "threads". The kernel allows processes to share
resources and thus they can achieve legacy "threads" behavior without
requiring additional data structures and mechanisms in the kernel. The
power of implementing threads in this manner comes not only from
its simplicity but also from allowing application programmers to work
outside the confinement of all-or-nothing shared resources of legacy
threads. On Linux, at the time of thread creation using the clone system
call, applications can selectively choose which resources to share
between threads.
unshare system call adds a primitive to the Linux thread model that
allows threads to selectively 'unshare' any resources that were being
shared at the time of their creation. unshare was conceptualized by
Al Viro in the August of 2000, on the Linux-Kernel mailing list, as part
of the discussion on POSIX threads on Linux. unshare augments the
usefulness of Linux threads for applications that would like to control
shared resources without creating a new process. unshare is a natural
addition to the set of available primitives on Linux that implement
the concept of process/thread as a virtual machine.
2) Benefits
-----------
unshare would be useful to large application frameworks such as PAM
where creating a new process to control sharing/unsharing of process
resources is not possible. Since namespaces are shared by default
when creating a new process using fork or clone, unshare can benefit
even non-threaded applications if they have a need to disassociate
from default shared namespace. The following lists two use-cases
where unshare can be used.
2.1 Per-security context namespaces
-----------------------------------
unshare can be used to implement polyinstantiated directories using
the kernel's per-process namespace mechanism. Polyinstantiated directories,
such as per-user and/or per-security context instance of /tmp, /var/tmp or
per-security context instance of a user's home directory, isolate user
processes when working with these directories. Using unshare, a PAM
module can easily setup a private namespace for a user at login.
Polyinstantiated directories are required for Common Criteria certification
with Labeled System Protection Profile, however, with the availability
of shared-tree feature in the Linux kernel, even regular Linux systems
can benefit from setting up private namespaces at login and
polyinstantiating /tmp, /var/tmp and other directories deemed
appropriate by system administrators.
2.2 unsharing of virtual memory and/or open files
-------------------------------------------------
Consider a client/server application where the server is processing
client requests by creating processes that share resources such as
virtual memory and open files. Without unshare, the server has to
decide what needs to be shared at the time of creating the process
which services the request. unshare allows the server an ability to
disassociate parts of the context during the servicing of the
request. For large and complex middleware application frameworks, this
ability to unshare after the process was created can be very
useful.
3) Cost
-------
In order to not duplicate code and to handle the fact that unshare
works on an active task (as opposed to clone/fork working on a newly
allocated inactive task) unshare had to make minor reorganizational
changes to copy_* functions utilized by clone/fork system call.
There is a cost associated with altering existing, well tested and
stable code to implement a new feature that may not get exercised
extensively in the beginning. However, with proper design and code
review of the changes and creation of an unshare test for the LTP
the benefits of this new feature can exceed its cost.
4) Requirements
---------------
unshare reverses sharing that was done using clone(2) system call,
so unshare should have a similar interface as clone(2). That is,
since flags in clone(int flags, void *stack) specifies what should
be shared, similar flags in unshare(int flags) should specify
what should be unshared. Unfortunately, this may appear to invert
the meaning of the flags from the way they are used in clone(2).
However, there was no easy solution that was less confusing and that
allowed incremental context unsharing in future without an ABI change.
unshare interface should accommodate possible future addition of
new context flags without requiring a rebuild of old applications.
If and when new context flags are added, unshare design should allow
incremental unsharing of those resources on an as needed basis.
5) Functional Specification
---------------------------
NAME
unshare - disassociate parts of the process execution context
SYNOPSIS
#include <sched.h>
int unshare(int flags);
DESCRIPTION
unshare allows a process to disassociate parts of its execution
context that are currently being shared with other processes. Part
of execution context, such as the namespace, is shared by default
when a new process is created using fork(2), while other parts,
such as the virtual memory, open file descriptors, etc, may be
shared by explicit request to share them when creating a process
using clone(2).
The main use of unshare is to allow a process to control its
shared execution context without creating a new process.
The flags argument specifies one or bitwise-or'ed of several of
the following constants.
CLONE_FS
If CLONE_FS is set, file system information of the caller
is disassociated from the shared file system information.
CLONE_FILES
If CLONE_FILES is set, the file descriptor table of the
caller is disassociated from the shared file descriptor
table.
CLONE_NEWNS
If CLONE_NEWNS is set, the namespace of the caller is
disassociated from the shared namespace.
CLONE_VM
If CLONE_VM is set, the virtual memory of the caller is
disassociated from the shared virtual memory.
RETURN VALUE
On success, zero returned. On failure, -1 is returned and errno is
ERRORS
EPERM CLONE_NEWNS was specified by a non-root process (process
without CAP_SYS_ADMIN).
ENOMEM Cannot allocate sufficient memory to copy parts of caller's
context that need to be unshared.
EINVAL Invalid flag was specified as an argument.
CONFORMING TO
The unshare() call is Linux-specific and should not be used
in programs intended to be portable.
SEE ALSO
clone(2), fork(2)
6) High Level Design
--------------------
Depending on the flags argument, the unshare system call allocates
appropriate process context structures, populates it with values from
the current shared version, associates newly duplicated structures
with the current task structure and releases corresponding shared
versions. Helper functions of clone (copy_*) could not be used
directly by unshare because of the following two reasons.
1) clone operates on a newly allocated not-yet-active task
structure, where as unshare operates on the current active
task. Therefore unshare has to take appropriate task_lock()
before associating newly duplicated context structures
2) unshare has to allocate and duplicate all context structures
that are being unshared, before associating them with the
current task and releasing older shared structures. Failure
do so will create race conditions and/or oops when trying
to backout due to an error. Consider the case of unsharing
both virtual memory and namespace. After successfully unsharing
vm, if the system call encounters an error while allocating
new namespace structure, the error return code will have to
reverse the unsharing of vm. As part of the reversal the
system call will have to go back to older, shared, vm
structure, which may not exist anymore.
Therefore code from copy_* functions that allocated and duplicated
current context structure was moved into new dup_* functions. Now,
copy_* functions call dup_* functions to allocate and duplicate
appropriate context structures and then associate them with the
task structure that is being constructed. unshare system call on
the other hand performs the following:
1) Check flags to force missing, but implied, flags
2) For each context structure, call the corresponding unshare
helper function to allocate and duplicate a new context
structure, if the appropriate bit is set in the flags argument.
3) If there is no error in allocation and duplication and there
are new context structures then lock the current task structure,
associate new context structures with the current task structure,
and release the lock on the current task structure.
4) Appropriately release older, shared, context structures.
7) Low Level Design
-------------------
Implementation of unshare can be grouped in the following 4 different
items:
a) Reorganization of existing copy_* functions
b) unshare system call service function
c) unshare helper functions for each different process context
d) Registration of system call number for different architectures
7.1) Reorganization of copy_* functions
Each copy function such as copy_mm, copy_namespace, copy_files,
etc, had roughly two components. The first component allocated
and duplicated the appropriate structure and the second component
linked it to the task structure passed in as an argument to the copy
function. The first component was split into its own function.
These dup_* functions allocated and duplicated the appropriate
context structure. The reorganized copy_* functions invoked
their corresponding dup_* functions and then linked the newly
duplicated structures to the task structure with which the
copy function was called.
7.2) unshare system call service function
* Check flags
Force implied flags. If CLONE_THREAD is set force CLONE_VM.
If CLONE_VM is set, force CLONE_SIGHAND. If CLONE_SIGHAND is
set and signals are also being shared, force CLONE_THREAD. If
CLONE_NEWNS is set, force CLONE_FS.
* For each context flag, invoke the corresponding unshare_*
helper routine with flags passed into the system call and a
reference to pointer pointing the new unshared structure
* If any new structures are created by unshare_* helper
functions, take the task_lock() on the current task,
modify appropriate context pointers, and release the
task lock.
* For all newly unshared structures, release the corresponding
older, shared, structures.
7.3) unshare_* helper functions
For unshare_* helpers corresponding to CLONE_SYSVSEM, CLONE_SIGHAND,
and CLONE_THREAD, return -EINVAL since they are not implemented yet.
For others, check the flag value to see if the unsharing is
required for that structure. If it is, invoke the corresponding
dup_* function to allocate and duplicate the structure and return
a pointer to it.
7.4) Appropriately modify architecture specific code to register the
the new system call.
8) Test Specification
---------------------
The test for unshare should test the following:
1) Valid flags: Test to check that clone flags for signal and
signal handlers, for which unsharing is not implemented
yet, return -EINVAL.
2) Missing/implied flags: Test to make sure that if unsharing
namespace without specifying unsharing of filesystem, correctly
unshares both namespace and filesystem information.
3) For each of the four (namespace, filesystem, files and vm)
supported unsharing, verify that the system call correctly
unshares the appropriate structure. Verify that unsharing
them individually as well as in combination with each
other works as expected.
4) Concurrent execution: Use shared memory segments and futex on
an address in the shm segment to synchronize execution of
about 10 threads. Have a couple of threads execute execve,
a couple _exit and the rest unshare with different combination
of flags. Verify that unsharing is performed as expected and
that there are no oops or hangs.
9) Future Work
--------------
The current implementation of unshare does not allow unsharing of
signals and signal handlers. Signals are complex to begin with and
to unshare signals and/or signal handlers of a currently running
process is even more complex. If in the future there is a specific
need to allow unsharing of signals and/or signal handlers, it can
be incrementally added to unshare without affecting legacy
applications using unshare.
