2025-06-19arm64: dts: rockchip: add version-independent WiFi/BT nodes on Sige5Alexey Charkov
ArmSoM Sige5 uses a soldered-on WiFi/BT module with WiFi on SDIO and BT on UART. However, board v1.1 uses a Realtek based BL-M8852BS2, while v1.2 uses a Broadcom based BW3752-50B1. They use the same pins and controllers, but require different DT properties to enable. Thankfully, the WiFi part at least works without explicitly listing it in the device tree, albeit without OOB interrupt functionality. Add required device tree nodes that do not depend on the board version so that at least the WiFi module can appear on the SDIO bus. WiFi OOB interrupt and Bluetooth function support are not enabled here, as they require module specific properties.

2025-06-10arm64: dts: rockchip: Add Luckfox Omni3576 Board supportJohn Clark
Add device tree for the Luckfox Omni3576 Carrier Board with Core3576 Module, powered by the Rockchip RK3576 SoC with four Cortex-A72 cores, four Cortex-A53 cores, and a Mali-G52 MC3 GPU. This initial implementation enables essential functionality for booting Linux and basic connectivity. Supported and tested features: - UART for serial console - SD card for storage - PCIe with NVMe SSD (detected, mounted, and fully functional) - USB 2.0 host ports - RK806 PMIC for power management - RTC with timekeeping and wake-up - GPIO-controlled LED with heartbeat trigger - eMMC (enabled, not populated on tested board) The device tree provides a foundation for further peripheral support, such as WiFi, MIPI-DSI, HDMI, and Ethernet, in future updates. Tested on Linux 6.15-rc4 Based on the Luckfox SDK, which derives from Rockchip’s SDK examples, with relevant changes to align with upstream Linux.

2025-06-10arm64: dts: rockchip: Remove workaround that prevented Turing RK1 GPU power ↵Sam Edwards
regulator control The RK3588 GPU power domain cannot be activated unless the external power regulator is already on. When GPU support was added to this DT, we had no way to represent this requirement, so `regulator-always-on` was added to the `vdd_gpu_s0` regulator in order to ensure stability. A later patch series (see "Fixes:" commit) resolved this shortcoming, but that commit left the workaround -- and rendered the comment above it no longer correct. Remove the workaround to allow the GPU power regulator to power off, now that the DT includes the necessary information to power it back on correctly.

2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

2025-06-08tools/power turbostat: Always check rapl_joules flagZhang Rui
rapl_joules bit should always be checked even if platform_features->rapl_msrs is not set or no_msr flag is used. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2025-06-08tools/power turbostat: Fix AMD package-energy reportingGautham R. Shenoy
commit 05a2f07db888 ("tools/power turbostat: read RAPL counters via perf") that adds support to read RAPL counters via perf defines the notion of a RAPL domain_id which is set to physical_core_id on platforms which support per_core_rapl counters (Eg: AMD processors Family 17h onwards) and is set to the physical_package_id on all the other platforms. However, the physical_core_id is only unique within a package and on platforms with multiple packages more than one core can have the same physical_core_id and thus the same domain_id. (For eg, the first cores of each package have the physical_core_id = 0). This results in all these cores with the same physical_core_id using the same entry in the rapl_counter_info_perdomain[]. Since rapl_perf_init() skips the perf-initialization for cores whose domain_ids have already been visited, cores that have the same physical_core_id always read the perf file corresponding to the physical_core_id of the first package and thus the package-energy is incorrectly reported to be the same value for different packages. Note: This issue only arises when RAPL counters are read via perf and not when they are read via MSRs since in the latter case the MSRs are read separately on each core. Fix this issue by associating each CPU with rapl_core_id which is unique across all the packages in the system.

2025-06-08tools/power turbostat: Add Android support for MSR device handlingKaushlendra Kumar
It uses /dev/msrN device paths on Android instead of /dev/cpu/N/msr, updates error messages and permission checks to reflect the Android device path, and wraps platform-specific code with #if defined(ANDROID) to ensure correct behavior on both Android and non-Android systems. These changes improve compatibility and usability of turbostat on Android devices. Signed-off-by: Kaushlendra Kumar <kaushlendra.kumar@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

This "worked" as the subsequent allocations resized the domain, but the recent change to move the prepare() call into the domain creation path broke this works by chance mechanism. Size the domain properly at creation time" * tag 'irq-urgent-2025-06-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: PCI/MSI: Size device MSI domain with the maximum number of vectors
