Syscalls made from within an active transaction will not be performed and the

transaction will be doomed by the kernel with the failure code TM_CAUSE_SYSCALL

|
||||
Performing syscalls from within transaction is not recommended, and can lead
|
||||
to unpredictable results.
|
||||
|
||||
Syscalls made from within a suspended transaction are performed as normal and
|
||||
the transaction is not explicitly doomed by the kernel. However, what the
|
||||
kernel does to perform the syscall may result in the transaction being doomed
|
||||
by the hardware. The syscall is performed in suspended mode so any side
|
||||
effects will be persistent, independent of transaction success or failure. No
|
||||
guarantees are provided by the kernel about which syscalls will affect
|
||||
transaction success.
|
||||
Syscalls do not by design abort transactions, but beware: The kernel code will
|
||||
not be running in transactional state. The effect of syscalls will always
|
||||
remain visible, but depending on the call they may abort your transaction as a
|
||||
side-effect, read soon-to-be-aborted transactional data that should not remain
|
||||
invisible, etc. If you constantly retry a transaction that constantly aborts
|
||||
itself by calling a syscall, you'll have a livelock & make no progress.
|
||||
|
||||
Care must be taken when relying on syscalls to abort during active transactions
|
||||
if the calls are made via a library. Libraries may cache values (which may
|
||||
give the appearance of success) or perform operations that cause transaction
|
||||
failure before entering the kernel (which may produce different failure codes).
|
||||
Examples are glibc's getpid() and lazy symbol resolution.
|
||||
Simple syscalls (e.g. sigprocmask()) "could" be OK. Even things like write()
|
||||
from, say, printf() should be OK as long as the kernel does not access any
|
||||
memory that was accessed transactionally.
|

Consider any syscalls that happen to work as debug-only -- not recommended for

2. Power models
|
||||
|
||||
The power API registration functions provide a simple power model for
|
||||
CPUs. The current power is calculated as dynamic + (optionally)
|
||||
static power. This power model requires that the operating-points of
|
||||
the CPUs are registered using the kernel's opp library and the
|
||||
`cpufreq_frequency_table` is assigned to the `struct device` of the
|
||||
cpu. If you are using CONFIG_CPUFREQ_DT then the
|
||||
`cpufreq_frequency_table` should already be assigned to the cpu
|
||||
device.
|
||||
|
||||
The `plat_static_func` parameter of `cpufreq_power_cooling_register()`
|
||||
and `of_cpufreq_power_cooling_register()` is optional. If you don't
|
||||
provide it, only dynamic power will be considered.
|
||||
|
||||
2.1 Dynamic power
|
||||
|
||||
The dynamic power consumption of a processor depends on many factors.
|
||||
For a given processor implementation the primary factors are:
|
||||
|
||||
- The time the processor spends running, consuming dynamic power, as
|
||||
compared to the time in idle states where dynamic consumption is
|
||||
negligible. Herein we refer to this as 'utilisation'.
|
||||
- The voltage and frequency levels as a result of DVFS. The DVFS
|
||||
level is a dominant factor governing power consumption.
|
||||
- In running time the 'execution' behaviour (instruction types, memory
|
||||
access patterns and so forth) causes, in most cases, a second order
|
||||
variation. In pathological cases this variation can be significant,
|
||||
but typically it is of a much lesser impact than the factors above.
|
||||
|
||||
A high level dynamic power consumption model may then be represented as:
|
||||
|
||||
Pdyn = f(run) * Voltage^2 * Frequency * Utilisation
|
||||
|
||||
f(run) here represents the described execution behaviour and its
|
||||
result has a units of Watts/Hz/Volt^2 (this often expressed in
|
||||
mW/MHz/uVolt^2)
|
||||
|
||||
The detailed behaviour for f(run) could be modelled on-line. However,
|
||||
in practice, such an on-line model has dependencies on a number of
|
||||
implementation specific processor support and characterisation
|
||||
factors. Therefore, in initial implementation that contribution is
|
||||
represented as a constant coefficient. This is a simplification
|
||||
consistent with the relative contribution to overall power variation.
|
||||
|
||||
In this simplified representation our model becomes:
|
||||
|
||||
Pdyn = Capacitance * Voltage^2 * Frequency * Utilisation
|
||||
|
||||
Where `capacitance` is a constant that represents an indicative
|
||||
running time dynamic power coefficient in fundamental units of
|
||||
mW/MHz/uVolt^2. Typical values for mobile CPUs might lie in range
|
||||
from 100 to 500. For reference, the approximate values for the SoC in
|
||||
ARM's Juno Development Platform are 530 for the Cortex-A57 cluster and
|
||||
140 for the Cortex-A53 cluster.
|
||||
|
||||
|
||||
2.2 Static power
|
||||
|
||||
Static leakage power consumption depends on a number of factors. For a
|
||||
given circuit implementation the primary factors are:
|
||||
|
||||
- Time the circuit spends in each 'power state'
|
||||
- Temperature
|
||||
- Operating voltage
|
||||
- Process grade
|
||||
|
||||
The time the circuit spends in each 'power state' for a given
|
||||
evaluation period at first order means OFF or ON. However,
|
||||
'retention' states can also be supported that reduce power during
|
||||
inactive periods without loss of context.
|
||||
|
||||
Note: The visibility of state entries to the OS can vary, according to
|
||||
platform specifics, and this can then impact the accuracy of a model
|
||||
based on OS state information alone. It might be possible in some
|
||||
cases to extract more accurate information from system resources.
|
||||
|
||||
The temperature, operating voltage and process 'grade' (slow to fast)
|
||||
of the circuit are all significant factors in static leakage power
|
||||
consumption. All of these have complex relationships to static power.
|
||||
|
||||
Circuit implementation specific factors include the chosen silicon
|
||||
process as well as the type, number and size of transistors in both
|
||||
the logic gates and any RAM elements included.
|
||||
|
||||
The static power consumption modelling must take into account the
|
||||
power managed regions that are implemented. Taking the example of an
|
||||
ARM processor cluster, the modelling would take into account whether
|
||||
each CPU can be powered OFF separately or if only a single power
|
||||
region is implemented for the complete cluster.
|
||||
|
||||
In one view, there are others, a static power consumption model can
|
||||
then start from a set of reference values for each power managed
|
||||
region (e.g. CPU, Cluster/L2) in each state (e.g. ON, OFF) at an
|
||||
arbitrary process grade, voltage and temperature point. These values
|
||||
are then scaled for all of the following: the time in each state, the
|
||||
process grade, the current temperature and the operating voltage.
|
||||
However, since both implementation specific and complex relationships
|
||||
dominate the estimate, the appropriate interface to the model from the
|
||||
cpu cooling device is to provide a function callback that calculates
|
||||
the static power in this platform. When registering the cpu cooling
|
||||
device pass a function pointer that follows the `get_static_t`
|
||||
prototype:
|
||||
|
||||
int plat_get_static(cpumask_t *cpumask, int interval,
|
||||
unsigned long voltage, u32 &power);
|
||||
|
||||
`cpumask` is the cpumask of the cpus involved in the calculation.
|
||||
`voltage` is the voltage at which they are operating. The function
|
||||
should calculate the average static power for the last `interval`
|
||||
milliseconds. It returns 0 on success, -E* on error. If it
|
||||
succeeds, it should store the static power in `power`. Reading the
|
||||
temperature of the cpus described by `cpumask` is left for
|
||||
plat_get_static() to do as the platform knows best which thermal
|
||||
sensor is closest to the cpu.
|
||||
|
||||
If `plat_static_func` is NULL, static power is considered to be
|
||||
negligible for this platform and only dynamic power is considered.
|
||||
|
||||
The platform specific callback can then use any combination of tables
|
||||
and/or equations to permute the estimated value. Process grade
|
||||
information is not passed to the model since access to such data, from
|
||||
on-chip measurement capability or manufacture time data, is platform
|
||||
specific.
|
||||
|
||||
Note: the significance of static power for CPUs in comparison to
|
||||
dynamic power is highly dependent on implementation. Given the
|
||||
potential complexity in implementation, the importance and accuracy of
|
||||
its inclusion when using cpu cooling devices should be assessed on a
|
||||
case by case basis.

Power allocator governor tunables
|
||||
=================================
|
||||
|
||||
Trip points
|
||||
-----------
|
||||
|
||||
The governor requires the following two passive trip points:
|
||||
|
||||
1. "switch on" trip point: temperature above which the governor
|
||||
control loop starts operating. This is the first passive trip
|
||||
point of the thermal zone.
|
||||
|
||||
2. "desired temperature" trip point: it should be higher than the
|
||||
"switch on" trip point. This the target temperature the governor
|
||||
is controlling for. This is the last passive trip point of the
|
||||
thermal zone.
|
||||
|
||||
PID Controller
|
||||
--------------
|
||||
|
||||
The power allocator governor implements a
|
||||
Proportional-Integral-Derivative controller (PID controller) with
|
||||
temperature as the control input and power as the controlled output:
|
||||
|
||||
P_max = k_p * e + k_i * err_integral + k_d * diff_err + sustainable_power
|
||||
|
||||
where
|
||||
e = desired_temperature - current_temperature
|
||||
err_integral is the sum of previous errors
|
||||
diff_err = e - previous_error
|
||||
|
||||
It is similar to the one depicted below:

|
||||
|
||||
Sustainable power
|
||||
-----------------
|
||||
|
||||
An estimate of the sustainable dissipatable power (in mW) should be
|
||||
provided while registering the thermal zone. This estimates the
|
||||
sustained power that can be dissipated at the desired control
|
||||
temperature. This is the maximum sustained power for allocation at
|
||||
the desired maximum temperature. The actual sustained power can vary
|
||||
for a number of reasons. The closed loop controller will take care of
|
||||
variations such as environmental conditions, and some factors related
|
||||
to the speed-grade of the silicon. `sustainable_power` is therefore
|
||||
simply an estimate, and may be tuned to affect the aggressiveness of
|
||||
the thermal ramp. For reference, the sustainable power of a 4" phone
|
||||
is typically 2000mW, while on a 10" tablet is around 4500mW (may vary
|
||||
depending on screen size).
|
||||
|
||||
If you are using device tree, do add it as a property of the
|
||||
thermal-zone. For example:
|
||||
|
||||
thermal-zones {
|
||||
soc_thermal {
|
||||
polling-delay = <1000>;
|
||||
polling-delay-passive = <100>;
|
||||
sustainable-power = <2500>;
|
||||
...
|
||||
|
||||
Instead, if the thermal zone is registered from the platform code, pass a
|
||||
`thermal_zone_params` that has a `sustainable_power`. If no
|
||||
`thermal_zone_params` were being passed, then something like below
|
||||
will suffice:
|
||||
|
||||
static const struct thermal_zone_params tz_params = {
|
||||
.sustainable_power = 3500,
|
||||
};
|
||||
|
||||
and then pass `tz_params` as the 5th parameter to
|
||||
`thermal_zone_device_register()`
|
||||
|
||||
k_po and k_pu
|
||||
-------------
|
||||
|
||||
The implementation of the PID controller in the power allocator
|
||||
thermal governor allows the configuration of two proportional term
|
||||
constants: `k_po` and `k_pu`. `k_po` is the proportional term
|
||||
constant during temperature overshoot periods (current temperature is
|
||||
above "desired temperature" trip point). Conversely, `k_pu` is the
|
||||
proportional term constant during temperature undershoot periods
|
||||
(current temperature below "desired temperature" trip point).
|
||||
|
||||
These controls are intended as the primary mechanism for configuring
|
||||
the permitted thermal "ramp" of the system. For instance, a lower
|
||||
`k_pu` value will provide a slower ramp, at the cost of capping
|
||||
available capacity at a low temperature. On the other hand, a high
|
||||
value of `k_pu` will result in the governor granting very high power
|
||||
whilst temperature is low, and may lead to temperature overshooting.
|
||||
|
||||
The default value for `k_pu` is:
|
||||
|
||||
2 * sustainable_power / (desired_temperature - switch_on_temp)
|
||||
|
||||
This means that at `switch_on_temp` the output of the controller's
|
||||
proportional term will be 2 * `sustainable_power`. The default value
|
||||
for `k_po` is:
|
||||
|
||||
sustainable_power / (desired_temperature - switch_on_temp)
|
||||
|
||||
Focusing on the proportional and feed forward values of the PID
|
||||
controller equation we have:
|
||||
|
||||
P_max = k_p * e + sustainable_power
|
||||
|
||||
The proportional term is proportional to the difference between the
|
||||
desired temperature and the current one. When the current temperature
|
||||
is the desired one, then the proportional component is zero and
|
||||
`P_max` = `sustainable_power`. That is, the system should operate in
|
||||
thermal equilibrium under constant load. `sustainable_power` is only
|
||||
an estimate, which is the reason for closed-loop control such as this.
|
||||
|
||||
Expanding `k_pu` we get:
|
||||
P_max = 2 * sustainable_power * (T_set - T) / (T_set - T_on) +
|
||||
sustainable_power
|
||||
|
||||
where
|
||||
T_set is the desired temperature
|
||||
T is the current temperature
|
||||
T_on is the switch on temperature
|
||||
|
||||
When the current temperature is the switch_on temperature, the above
|
||||
formula becomes:
|
||||
|
||||
P_max = 2 * sustainable_power * (T_set - T_on) / (T_set - T_on) +
|
||||
sustainable_power = 2 * sustainable_power + sustainable_power =
|
||||
3 * sustainable_power
|
||||
|
||||
Therefore, the proportional term alone linearly decreases power from
|
||||
3 * `sustainable_power` to `sustainable_power` as the temperature
|
||||
rises from the switch on temperature to the desired temperature.
|
||||
|
||||
k_i and integral_cutoff
|
||||
-----------------------
|
||||
|
||||
`k_i` configures the PID loop's integral term constant. This term
|
||||
allows the PID controller to compensate for long term drift and for
|
||||
the quantized nature of the output control: cooling devices can't set
|
||||
the exact power that the governor requests. When the temperature
|
||||
error is below `integral_cutoff`, errors are accumulated in the
|
||||
integral term. This term is then multiplied by `k_i` and the result
|
||||
added to the output of the controller. Typically `k_i` is set low (1
|
||||
or 2) and `integral_cutoff` is 0.
|
||||
|
||||
k_d
|
||||
---
|
||||
|
||||
`k_d` configures the PID loop's derivative term constant. It's
|
||||
recommended to leave it as the default: 0.
|
||||
|
||||
Cooling device power API
|
||||
========================
|
||||
|
||||
Cooling devices controlled by this governor must supply the additional
|
||||
"power" API in their `cooling_device_ops`. It consists on three ops:
|
||||
|
||||
1. int get_requested_power(struct thermal_cooling_device *cdev,
|
||||
struct thermal_zone_device *tz, u32 *power);
|
||||
@cdev: The `struct thermal_cooling_device` pointer
|
||||
@tz: thermal zone in which we are currently operating
|
||||
@power: pointer in which to store the calculated power
|
||||
|
||||
`get_requested_power()` calculates the power requested by the device
|
||||
in milliwatts and stores it in @power . It should return 0 on
|
||||
success, -E* on failure. This is currently used by the power
|
||||
allocator governor to calculate how much power to give to each cooling
|
||||
device.
|
||||
|
||||
2. int state2power(struct thermal_cooling_device *cdev, struct
|
||||
thermal_zone_device *tz, unsigned long state, u32 *power);
|
||||
@cdev: The `struct thermal_cooling_device` pointer
|
||||
@tz: thermal zone in which we are currently operating
|
||||
@state: A cooling device state
|
||||
@power: pointer in which to store the equivalent power
|
||||
|
||||
Convert cooling device state @state into power consumption in
|
||||
milliwatts and store it in @power. It should return 0 on success, -E*
|
||||
on failure. This is currently used by thermal core to calculate the
|
||||
maximum power that an actor can consume.
|
||||
|
||||
3. int power2state(struct thermal_cooling_device *cdev, u32 power,
|
||||
unsigned long *state);
|
||||
@cdev: The `struct thermal_cooling_device` pointer
|
||||
@power: power in milliwatts
|
||||
@state: pointer in which to store the resulting state
|
||||
|
||||
Calculate a cooling device state that would make the device consume at
|
||||
most @power mW and store it in @state. It should return 0 on success,
|
||||
-E* on failure. This is currently used by the thermal core to convert
|
||||
a given power set by the power allocator governor to a state that the
|
||||
cooling device can set. It is a function because this conversion may
|
||||
depend on external factors that may change so this function should the
|
||||
best conversion given "current circumstances".
|
||||
|
||||
Cooling device weights
|
||||
----------------------
|
||||
|
||||
Weights are a mechanism to bias the allocation among cooling
|
||||
devices. They express the relative power efficiency of different
|
||||
cooling devices. Higher weight can be used to express higher power
|
||||
efficiency. Weighting is relative such that if each cooling device
|
||||
has a weight of one they are considered equal. This is particularly
|
||||
useful in heterogeneous systems where two cooling devices may perform
|
||||
the same kind of compute, but with different efficiency. For example,
|
||||
a system with two different types of processors.
|
||||
|
||||
If the thermal zone is registered using
|
||||
`thermal_zone_device_register()` (i.e., platform code), then weights
|
||||
are passed as part of the thermal zone's `thermal_bind_parameters`.
|
||||
If the platform is registered using device tree, then they are passed
|
||||
as the `contribution` property of each map in the `cooling-maps` node.
|
||||

||||
Limitations of the power allocator governor
|
||||
===========================================
|
||||
|
||||
The power allocator governor's PID controller works best if there is a
|
||||
periodic tick. If you have a driver that calls
|
||||
`thermal_zone_device_update()` (or anything that ends up calling the
|
||||
governor's `throttle()` function) repetitively, the governor response
|
||||
won't be very good. Note that this is not particular to this
|
||||
governor, step-wise will also misbehave if you call its throttle()

example) as it will overreact.
