This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

| * powercap/drivers/idle_inject: Specify idle state max latencyDaniel Lezcano2020-05-191-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | powercap: idle_inject: Replace zero-length array with flexible-array memberGustavo A. R. Silva2020-03-041-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Lastly, fix the following checkpatch warning: WARNING: Prefer 'unsigned long' over 'unsigned long int' as the int is unnecessary + unsigned long int cpumask[]; This issue was found with the help of Coccinelle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The resolution of the idle injection is limited to 1ms. If there is a need for an injection of 1.2 ms, it is not possible.

* powercap: Invoke powercap_init() and rapl_init() earlierZhang Rui2019-07-222-2/+2
| | | | | | | | | | | | | | | | | | The MMIO RAPL interface driver depends on both powercap subsystem and the intel_rapl_common code. But when all of them are built-in, the MMIO RAPL interface driver can be loaded before the other two and this breaks the system during boot. Fix this by adjusting the init order of the powercap subsystem and the intel_rapl_common code, so that it can be initialized first.

* intel_rapl: Fix module autoloading issueZhang Rui2019-07-112-21/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | intel_rapl driver used to have a list of cpuids, which is used to 1. check if the processor support RAPL MSRs 2. do some cpu model specific setting 3. module autoloading Now, the cpu model specific setting are moved to intel_rapl_common.c as part of the common code, because the setup is also needed by RAPL MMIO interface on those platforms. But removing the cpuid list from intel_rapl MSR interface driver results in that the driver can not be loaded automatically. Maintaining another copy of the cpuid list in intel_rapl_msr.c does not make sense because it increases the complexity when enabling RAPL support on a new cpu model. Fix the problem by creating an "intel_rapl_msr" platform device in the common code, and make RAPL MSR interface driver (intel_rapl_msr.c) probe the platform device directly.

This is confusing as the function name does not describe what it does clearly. With this patch, the three functions are removed, and two new functions rapl_register_platform_domain()/rapl_unregister_platform_domain() are introduced instead, and they do exactly what their function name describes. Plus, as part of the common code, hardcoded MSR accesses in these functions are converted to follow the abstracted register access.
