powercap/intel_rapl: fix and tidy up error handling

2017-01-19T19:18:07Z

commit cb43f81b8489dcb87555e16c17453f0a9fa690f2 upstream. Commit e1399ba20eee ("powercap / RAPL: handle missing MSRs") added contraint_to_pl() function to return index into an array. But it can potentially return -EINVAL if powercap layer sends an out of range constraint ID. This patch adds sanity check. Unnecessary RAPL domain pointer check is removed since it must be initialized before calling rapl_unit_xlate().

x86/cpu: Rename Merrifield2 to Moorefield

2016-09-08T06:13:08Z

Merrifield2 is actually Moorefield. Rename it accordingly and drop tail digit from Merrifield1.

powercap / RAPL: Add support for Ivy Bridge server

2016-06-25T01:00:58Z

It's confirmed that RAPL works as expected on Ivy Bridge servers. Tested against processor: Intel(R) Xeon(R) CPU E5-2697 v2 @2.70GHz Signed-off-by: Xiaolong Wang Signed-off-by: Rafael J. Wysocki

powercap / RAPL: add support for Denverton

powercap / RAPL: handle missing MSRs

2016-06-14T23:33:50Z

Some RAPL MSRs may not exist on some CPUs, we need to continue the topology detection and enumerate what is available. This patch handles the missing MSRs, then reports to the powercap layer only the features available. Signed-off-by: Jacob Pan Signed-off-by: Rafael J. Wysocki

powercap / RAPL: reduce message loglevel

2016-06-10T00:32:32Z

Since the RAPL interface is not architectual, its enumeration depends on poking MSRs instead of using the CPUID method. In KVM guests, the RAPL driver probe will fail and emit the following message for every CPU: "no valid rapl domains found in package" This patch converts the warning to a debug message only (still return -ENODEV so that RAPL does not run in KVM guests).

Let's make an effort to group these things by microarchitecture name. It makes it easier to see if something got missed. Signed-off-by: Dave Hansen Acked-by: Rafael J.
