PowerCap: Fix an error code in powercap_register_zone()

2018-04-13T17:50:05Z

[ Upstream commit 216c4e9db4c9d1d2a382b42880442dc632cd47d9 ] In the current code we accidentally return the successful result from idr_alloc() instead of a negative error pointer. The caller is looking for an error pointer and so it treats the returned value as a valid pointer. This one might be a bit serious because if it lets people get around the kernel's protection for remapping NULL. I'm not sure.

powercap / RAPL: fix BIOS lock check

2015-12-12T01:31:11Z

Intel RAPL initialized on several systems where the BIOS lock bit (msr 0x610, bit 63) was set. This occured because the return value of rapl_read_data_raw() was being checked, rather than the value of the variable passed in, locked. This patch properly implments the rapl_read_data_raw() call to check the variable locked, and now the Intel RAPL driver outputs the warning: intel_rapl: RAPL package 0 domain package locked by BIOS and does not initialize for the package.

powercap / RAPL: disable the 2nd power limit properly

2015-08-28T23:46:40Z

Let rapl_unregister_powercap() disable the second power limit only if it exists. Intel64 SDM Vol.3 14.9 says that the package domain has it but neither the power plane domain nor the DRAM domain has it. Signed-off-by: Seiichi Ikarashi Signed-off-by: Rafael J. Wysocki

powercap / RAPL: Floor frequency setting in Atom SoC

2015-05-04T22:51:22Z

CPU Floor frequency is set in BIOS for newer Atom SoCs. This patch handles configuration of floor frequency for different variants of Atom SoCs appropriately and ensures configuration of floor frequency is not done from driver for these newer Atom SoCs. Since address of the register for configuring floor frequency might change for different Atom SoCs, this patch also prevents potential overwriting of wrong registers.

powercap / RAPL: mark rapl_ids array as __initconst

2015-04-11T00:21:15Z

The RAPL ids are only tested in rapl_init() which is itself an __init function. For the MODULE_DEVICE_TABLE() file2alias doesn't care about the section, just about the symbol name. Therefore it's safe to mark the rapl_ids[] array as __initconst so its memory can be released after initialization is done. Signed-off-by: Mathias Krause Acked-by: Jacob Pan Signed-off-by: Rafael J.
