2026-04-01thermal: intel: int340x: processor: Move MMIO primitives to MMIO driverKuppuswamy Sathyanarayanan
MMIO-specific primitives differ from those used by the TPMI interface. The MSR and MMIO interfaces shared the same primitives in the common driver, but MMIO does not require many MSR-specific entries (like PSYS). Keeping these in the common driver does not add any value and requires interface-specific handling logic that makes the common layer unnecessarily complex. Move the MMIO primitive definitions and associated bitmasks into the MMIO interface driver. This change includes: 1. Add MMIO-local struct rapl_primitive_info instance without MSR-specific entries and assign it to priv->rpi during MMIO initialization. 2. Remove the RAPL MMIO case from rapl_config() in the common driver. No functional changes are intended.

2026-03-05thermal: intel: int340x: processor: Move RAPL defaults to MMIO driverKuppuswamy Sathyanarayanan
Previously, the MMIO and MSR RAPL interfaces shared the same set of RAPL defaults provided by common code. However, unlike the MSR interface, the MMIO RAPL interface does not require CPU-specific variations in its default handling. Keeping the RAPL defaults in the RAPL common driver therefore provides no additional benefit. Move the MMIO defaults into the MMIO interface driver. This change includes the following updates: * Introduce a MMIO-local rapl_defaults instance with the appropriate default callbacks. * Assign the MMIO-specific rapl_defaults to priv->defaults during MMIO driver initialization.

2026-03-05powercap: intel_rapl: Add a symbol namespace for intel_rapl exportsKuppuswamy Sathyanarayanan
Cleanup of the intel_rapl common driver requires introducing additional exported helper and lifecycle functions. Before adding new exports, create a dedicated symbol namespace for intel_rapl and update the relevant interface drivers to explicitly import it. This makes the intended usage of these symbols explicit, avoids polluting the global namespace, and prepares the codebase for the ongoing RAPL refactoring. No functional changes are intended.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-01-07thermal: int340x: processor_thermal: Enable slow workload type hintsSrinivas Pandruvada
On processors starting from Panther Lake, additional workload type hints are provided. The hardware analyzes workload residencies over an extended period to determine whether the workload classification tends toward idle/battery life states or sustained/performance states. Based on this long-term analysis, it classifies: Power Classification: If the workload exhibits more idle or battery life residencies, it is classified as "power". This is indicated by setting bit 4 of the current workload type. Performance Classification: If the workload exhibits more sustained or performance residencies, it is classified as "performance". This is indicated by clearing bit 4 of the current workload type. This approach enables applications to ignore short-term workload fluctuations and instead respond to longer-term power vs. performance trends. Hints of this type are called slow workload hints. To get notifications for slow workload hints, bit 22 in the thermal mailbox can be used for configuring workload interrupts. It is possible to exclusively enable slow workload hints or enable them in addition to the current workload hints. To enable slow workload hints, a new sysfs attribute is added to the existing workload hint attributes: workload_slow_hint_enable (RW): Write 1 to enable, 0 to disable. Reading this attribute shows the current state. This attribute is not present on any previous generation of processors.

2025-11-21powercap: intel_rapl: Prepare read_raw() interface for atomic-context callersKuppuswamy Sathyanarayanan
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.

The IRQ used by the Intel SoC DTS thermal device for critical overheating notification is listed in _CRS of device INT3401 which therefore needs to be enumerated for Intel SoC DTS thermal to work. The enumeration happens by binding the int3401_thermal driver to the INT3401 platform device. Thus CONFIG_INT340X_THERMAL is in fact necessary for enumerating it, so checking CONFIG_INTEL_SOC_DTS_THERMAL in int340x_thermal_handler_attach() is pointless and INT340X_THERMAL may as well be selected by INTEL_SOC_DTS_THERMAL.

When the module parameter slider_balance is set to the performance slider value of 0, the SoC slider profile switches to the performance mode. This can cause the Linux power-profiles-daemon to change the system power mode to performance from balanced mode. This happens when there is only one platform profile registered as there will be no conflict with other platform profiles. Same issue occurs when the slider_balance is set to the power-saver slider value. Prevent module parameter slider_balance from overlapping with performance and power-saver slider values by adding range validation. Return an error when an invalid value is provided.

SoC slider value is set by the user (or the default when user has not modified it). To enhance power efficiency dynamically, the firmware can optionally auto-adjust the slider value based on the current workload. This adjustment is governed by an additional parameter known as the "slider offset". This offset permits the firmware to increase the slider value up to and including "SoC slider + slider offset". Add a module parameter to specify this "slier offset" value. By default, the SoC slider offset is set to 0. This means that SoC is not allowed to switch slider position.

2025-06-16thermal: intel: int340x: Add throttling control interface to PTCSrinivas Pandruvada
Firmware-based thermal temperature control loops may aggressively throttle performance to prevent temperature overshoots relative to the defined target temperature. This can negatively impact performance. User space may prefer to prioritize performance, even if it results in temperature overshoots with in acceptable range. For example, user space might tolerate temperature overshoots when the device is placed on a desk, as opposed to when it's on a lap. To accommodate such scenarios, an optional attribute is provided to specify a tolerance level for temperature overshoots while maintaining acceptable performance. Attribute: thermal_tolerance: This attribute ranges from 0 to 7, where 0 represents the most aggressive control to avoid any temperature overshoots, and 7 represents a more graceful approach, favoring performance even at the expense of temperature overshoots. Note: This level may not scale linearly. For example, a value of 3 does not necessarily imply a 50% improvement in performance compared to a value of 0.
