thermal: intel: int340x: soc_slider: Set offset only for balanced mode

2026-04-02T11:25:41+00:00

commit 7dfe9846016b15816e287a4650be1ff1b48c5ab4 upstream. The slider offset can be set via debugfs for balanced mode. The offset should be only applicable in balanced mode. For other modes, it should be 0 when writing to MMIO offset, Fixes: 8306bcaba06d ("thermal: intel: int340x: Add module parameter to change slider offset") Tested-by: Erin Park Signed-off-by: Srinivas Pandruvada Cc: 6.18+ # 6.18+ [ rjw: Subject and changelog tweaks ] Link: https://patch.msgid.link/20260324172346.3317145-1-srinivas.pandruvada@linux.intel.com Signed-off-by: Rafael J.

thermal: int340x: Fix sysfs group leak on DLVR registration failure

2026-03-04T12:20:45+00:00

[ Upstream commit 15176b818e048ccf6ef4b96db34eda7b7e98938a ] When DLVR sysfs group creation fails in proc_thermal_rfim_add(), the function returns immediately without cleaning up the FIVR group that may have been created earlier. Add proper error unwinding to remove the FIVR group before returning failure.

thermal: intel: x86_pkg_temp_thermal: Handle invalid temperature

2026-02-26T23:00:42+00:00

[ Upstream commit 9635c586a559ba0e45b2bfbff79c937ddbaf1a62 ] After commit be0a3600aa1e ("thermal: sysfs: Rework the handling of trip point updates"), THERMAL_TEMP_INVALID can be passed to sys_set_trip_temp() and it is treated as a regular temperature value there, so the sysfs write fails even though it is expected to succeed and disable the given trip point. Address this by making sys_set_trip_temp() clear its temp variable when it is equal to THERMAL_TEMP_INVALID.

powercap: intel_rapl: Prepare read_raw() interface for atomic-context callers

2025-11-21T20:47:08+00:00

The current read_raw() implementation of the TPMI, MMIO and MSR interfaces does not distinguish between atomic and non-atomic callers. rapl_msr_read_raw() uses rdmsrq_safe_on_cpu(), which can sleep and issue cross CPU calls. When MSR-based RAPL PMU support is enabled, PMU event handlers can invoke this function from atomic context where sleeping or rescheduling is not allowed. In atomic context, the caller is already executing on the target CPU, so a direct rdmsrq() is sufficient. To support such usage, introduce an atomic flag to the read_raw() interface to allow callers pass the context information. Modify the common RAPL code to propagate this flag, and set the flag to reflect the calling contexts. Utilize the atomic flag in rapl_msr_read_raw() to perform direct MSR read with rdmsrq() when running in atomic context, and a sanity check to ensure target CPU matches the current CPU for such use cases. The TPMI and MMIO implementations do not require special atomic handling, so the flag is ignored in those paths. This is a preparatory patch for adding MSR-based RAPL PMU support.

syscore: Pass context data to callbacks

2025-11-14T09:01:52+00:00

Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J. Wysocki (Intel) Signed-off-by: Thierry Reding

Add support for DLVR (Digital Linear Voltage Regulator) for Nova Lake. There are no new sysfs attributes or difference in operations compared to prior generations. MMIO offset and bit positions are changed. Also no mapping is required as units are already in MHz.
