* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
|
||||
|
||||
On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
|
||||
sensors (THS) which are the analog circuits for measuring temperature (Tj)
|
||||
inside the LSI.
|
||||
|
||||
Required properties:
|
||||
- compatible : "renesas,<soctype>-thermal",
|
||||
Examples with soctypes are:
|
||||
- "renesas,r8a7795-thermal" (R-Car H3)
|
||||
- "renesas,r8a7796-thermal" (R-Car M3-W)
|
||||
- reg : Address ranges of the thermal registers. Each sensor
|
||||
needs one address range. Sorting must be done in
|
||||
increasing order according to datasheet, i.e.
|
||||
TSC1, TSC2, ...
|
||||
- clocks : Must contain a reference to the functional clock.
|
||||
- #thermal-sensor-cells : must be <1>.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- interrupts : interrupts routed to the TSC (3 for H3 and M3-W)
|
||||
- power-domain : Must contain a reference to the power domain. This
|
||||
property is mandatory if the thermal sensor instance
|
||||
is part of a controllable power domain.
|
||||
|
||||

4) Locking between applications
|
||||
|
||||
Certain operations on the resctrl filesystem, composed of read/writes
|
||||
to/from multiple files, must be atomic.
|
||||
|
||||
As an example, the allocation of an exclusive reservation of L3 cache
|
||||
involves:
|
||||
|
||||
1. Read the cbmmasks from each directory
|
||||
2. Find a contiguous set of bits in the global CBM bitmask that is clear
|
||||
in any of the directory cbmmasks
|
||||
3. Create a new directory
|
||||
4. Set the bits found in step 2 to the new directory "schemata" file
|
||||
|
||||
If two applications attempt to allocate space concurrently then they can
|
||||
end up allocating the same bits so the reservations are shared instead of
|
||||
exclusive.
|
||||
|
||||
To coordinate atomic operations on the resctrlfs and to avoid the problem
|
||||
above, the following locking procedure is recommended:
|
||||
|
||||
Locking is based on flock, which is available in libc and also as a shell
|
||||
script command
|
||||
|
||||
Write lock:
|
||||
|
||||
A) Take flock(LOCK_EX) on /sys/fs/resctrl
|
||||
B) Read/write the directory structure.
|
||||
C) funlock
|
||||
|
||||
Read lock:
|
||||
|
||||
A) Take flock(LOCK_SH) on /sys/fs/resctrl
|
||||
B) If success read the directory structure.
|
||||
C) funlock
|
||||
|
||||
Example with bash:
|
||||
|
||||
# Atomically read directory structure
|
||||
$ flock -s /sys/fs/resctrl/ find /sys/fs/resctrl
|
||||
|
||||
# Read directory contents and create new subdirectory
|
||||
|
||||
$ cat create-dir.sh
|
||||
find /sys/fs/resctrl/ > output.txt
|
||||
mask = function-of(output.txt)
|
||||
mkdir /sys/fs/resctrl/newres/
|
||||
echo mask > /sys/fs/resctrl/newres/schemata
|
||||
|
||||
$ flock /sys/fs/resctrl/ ./create-dir.sh
|
||||
|
||||

|
||||
|
||||

||||

|
||||
* before accessing resctrl filesystem
