2020-05-22thermal: imx8mm: Replace zero-length array with flexible-arrayGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

The cpuidle driver can be used as a cooling device by injecting idle cycles. When the property is set, register the cpuidle driver with the idle state node pointer as a cooling device.

2020-05-19thermal/drivers/cpuidle_cooling: Change the registration functionDaniel Lezcano
Today, there is no user for the cpuidle cooling device. The targetted platform is ARM and ARM64. The cpuidle and the cpufreq cooling device are based on the device tree. As the cpuidle cooling device can have its own configuration depending on the platform and the available idle states. The DT node description will give the optional properties to set the cooling device up. Do no longer rely on the CPU node which is prone to error and will lead to a confusion in the DT because the cpufreq cooling device is also using it. Let initialize the cpuidle cooling device with the DT binding.

2020-05-19powercap/drivers/idle_inject: Specify idle state max latencyDaniel Lezcano
Currently the idle injection framework uses the play_idle() function which puts the current CPU in an idle state. The idle state is the deepest one, as specified by the latency constraint when calling the subsequent play_idle_precise() function with the INT_MAX. The idle_injection is used by the cpuidle_cooling device which computes the idle / run duration to mitigate the temperature by injecting idle cycles. The cooling device has no control on the depth of the idle state. Allow finer control of the idle injection mechanism by allowing to specify the latency for the idle state. Thus the cooling device has the ability to have a guarantee on the exit latency of the idle states it is injecting. Acked-by: Rafael J.

2020-04-14thermal: k3: Add support for bandgap sensorsKeerthy
Add VTM thermal support. In the Voltage Thermal Management Module(VTM), K3 AM654 supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Currently reading temperatures only is supported. There are no active/passive cooling agent supported.

2020-04-10mm/vma: introduce VM_ACCESS_FLAGSAnshuman Khandual
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.
