2020-12-10KVM: s390: Add memcg accounting to KVM allocationsChristian Borntraeger
Almost all kvm allocations in the s390x KVM code can be attributed to the process that triggers the allocation (in other words, no global allocation for other guests). This will help the memcg controller to make the right decisions.

2020-12-10powerpc/perf: Exclude kernel samples while counting events in user space.Athira Rajeev
Perf event attritube supports exclude_kernel flag to avoid sampling/profiling in supervisor state (kernel). Based on this event attr flag, Monitor Mode Control Register bit is set to freeze on supervisor state. But sometimes (due to hardware limitation), Sampled Instruction Address Register (SIAR) locks on to kernel address even when freeze on supervisor is set. Patch here adds a check to drop those samples.

2020-12-10thermal: int340x: processor_thermal: Add RFIM driverSrinivas Pandruvada
Add support for RFIM (Radio Frequency Interference Mitigation) support via processor thermal PCI device. This drivers allows adjustment of FIVR (Fully Integrated Voltage Regulator) and DDR (Double Data Rate) frequencies to avoid RF interference with WiFi and 5G. Switching voltage regulators (VR) generate radiated EMI or RFI at the fundamental frequency and its harmonics. Some harmonics may interfere with very sensitive wireless receivers such as Wi-Fi and cellular that are integrated into host systems like notebook PCs. One of mitigation methods is requesting SOC integrated VR (IVR) switching frequency to a small % and shift away the switching noise harmonic interference from radio channels. OEM or ODMs can use the driver to control SOC IVR operation within the range where it does not impact IVR performance. DRAM devices of DDR IO interface and their power plane can generate EMI at the data rates. Similar to IVR control mechanism, Intel offers a mechanism by which DDR data rates can be changed if several conditions are met: there is strong RFI interference because of DDR; CPU power management has no other restriction in changing DDR data rates; PC ODMs enable this feature (real time DDR RFI Mitigation referred to as DDR-RFIM) for Wi-Fi from BIOS. This change exports two folders under /sys/bus/pci/devices/0000:00:04.0. One folder "fivr" contains all attributes exposed for controling FIVR features. The other folder "dvfs" contains all attributes for DDR features. Changes done to implement: - New module for rfim interfaces - Two new per processor features for DDR and FIVR - Enable feature for Tiger Lake (FIVR only) and Alder Lake The attributes exposed and explanation: FIVR attributes vco_ref_code_lo (RW): The VCO reference code is an 11-bit field and controls the FIVR switching frequency. This is the 3-bit LSB field. vco_ref_code_hi (RW): The VCO reference code is an 11-bit field and controls the FIVR switching frequency. This is the 8-bit MSB field. spread_spectrum_pct (RW): Set the FIVR spread spectrum clocking percentage spread_spectrum_clk_enable (RW): Enable/disable of the FIVR spread spectrum clocking feature rfi_vco_ref_code (RW): This field is a read only status register which reflects the current FIVR switching frequency fivr_fffc_rev (RW): This field indicated the revision of the FIVR HW. DVFS attributes rfi_restriction_run_busy (RW): Request the restriction of specific DDR data rate and set this value 1. Self reset to 0 after operation. rfi_restriction_err_code (RW): Values: 0 :Request is accepted, 1:Feature disabled, 2: the request restricts more points than it is allowed rfi_restriction_data_rate_Delta (RW): Restricted DDR data rate for RFI protection: Lower Limit rfi_restriction_data_rate_Base (RW): Restricted DDR data rate for RFI protection: Upper Limit ddr_data_rate_point_0 (RO): DDR data rate selection 1st point ddr_data_rate_point_1 (RO): DDR data rate selection 2nd point ddr_data_rate_point_2 (RO): DDR data rate selection 3rd point ddr_data_rate_point_3 (RO): DDR data rate selection 4th point rfi_disable (RW): Disable DDR rate change feature Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-3-srinivas.pandruvada@linux.intel.com

The Processor Thermal PCI device supports multiple features. Currently we export only RAPL. But we need more features from this device exposed for Tiger Lake and Alder Lake based platforms. So re-structure the current MMIO interface, so that more features can be added cleanly. No functional changes are expected with this change. Changes done in this patch: - Using PCI_DEVICE_DATA(), hence names of defines changed - Move RAPL MMIO code to its own module - Move the RAPL MMIO offsets to RAPL MMIO module - Adjust Kconfig dependency of PROC_THERMAL_MMIO_RAPL - Per processor driver data now contains the supported features - Moved all the common data structures and defines to a common header file - This new header file contains all the processor_thermal_* interfaces - Based on the features supported the module interface is called - Each module atleast provides one add and one remove function Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-1-srinivas.pandruvada@linux.intel.com

2020-12-10can: m_can: move runtime PM enable/disable to m_can_platformPatrik Flykt
This is a preparatory patch for upcoming PCI based M_CAN devices. The current PM implementation would cause PCI based drivers to enable PM twice, once when the PCI device is added and a second time in m_can_class_register(). This will cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that should be avoided. Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN class registration to its only user, the m_can_platform driver.

In opposite to normal and extended addressing this socket does not register a CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a segmented bi-directional data transfer.

2020-12-10zonefs: fix page reference and BIO leakDamien Le Moal
In zonefs_file_dio_append(), the pages obtained using bio_iov_iter_get_pages() are not released on completion of the REQ_OP_APPEND BIO, nor when bio_iov_iter_get_pages() fails. Furthermore, a call to bio_put() is missing when bio_iov_iter_get_pages() fails. Fix these resource leaks by adding BIO resource release code (bio_put()i and bio_release_pages()) at the end of the function after the BIO execution and add a jump to this resource cleanup code in case of bio_iov_iter_get_pages() failure. While at it, also fix the call to task_io_account_write() to be passed the correct BIO size instead of bio_iov_iter_get_pages() return value.
