2019-07-22powercap: Invoke powercap_init() and rapl_init() earlierZhang Rui1-1/+1
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.

2019-07-11intel_rapl: Fix module autoloading issueZhang Rui1-17/+28
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.

2019-07-11intel_rapl: support two power limits for every RAPL domainZhang Rui1-47/+25
RAPL MSR interface supports 2 power limits for package domain, and 1 power limit for other domains, while RAPL MMIO interface supports 2 power limits for both package and dram domains. And when 2 power limits are supported, the FW_LOCK bit is in bit 63 of the register, instead of bit 31. Remove the assumption that only pakcage domain supports 2 power limits. And allow the RAPL interface driver to specify the number of power limits supported, for every single RAPL domain it owns..

Split intel_rapl.c to intel_rapl_common.c and intel_rapl_msr.c, where intel_rapl_common.c contains the common code that can be used by both MSR and MMIO interface. intel_rapl_msr.c contains the implementation of RAPL MSR interface.
