2025-11-03Documentation: intel-pstate: Use :ref: directive for internal linkingBagas Sanjaya1-63/+70
intel_pstate docs uses standard reST construct (`Section title`_) for cross-referencing sections (internal linking), rather than for external links. Incorrect cross-references are not caught when these are written in that syntax, however (fortunately docutils 0.22 raise duplicate target warnings that get fixed in cb908f8b0acc7e ("Documentation: intel_pstate: fix duplicate hyperlink target errors")). Convert the cross-references to use :ref: directive, which doesn't exhibit this problem.

2025-11-03cxl/region: Add support to indicate region has extended linear cacheDave Jiang1-1/+10
Add a region sysfs attribute to show the size of the extended linear cache if there is any. The attribute is invisible when the cache size is 0, which indicates it does not exist. Moved the cxl_region_visible() location in order to pick up the new sysfs attribute definition.

The Mali-based GPU on the MediaTek MT8196 SoC uses a separate MCU to control the power and frequency of the GPU. This is modelled as a power domain and clock provider. It lets us omit the OPP tables from the device tree, as those can now be enumerated at runtime from the MCU. Add the necessary schema logic to handle what this SoC expects in terms of clocks and power-domains.

2025-11-02dt-bindings: clk: microchip: mpfs: remove first reg regionConor Dooley1-14/+22
The first reg region in this binding is not exclusively for clocks, as evidenced by the dual role of this device as a reset controller at present. The first region is however better described by a simple-mfd syscon, but this would have require a significant re-write of the devicetree for the platform, so the easy way out was chosen when reset support was first introduced. The region doesn't just contain clock and reset registers, it also contains pinctrl and interrupt controller functionality, so drop the region from the clock binding so that it can be described instead by a simple-mfd syscon rather than propagate this incorrect description of the hardware to the new pic64gx SoC.

2025-10-31dt-bindings: interconnect: add reg and clocks properties to enable QoS on ↵Odelu Kukatla1-1/+49
sa8775p Add 'reg' and 'clocks' properties to enable QoS configuration. These properties enable access to QoS registers and necessary clocks for configuration. QoS configuration is essential for ensuring that latency sensitive components such as CPUs and multimedia engines receive prioritized access to memory and interconnect resources. This helps to manage bandwidth and latency across subsystems, improving system responsiveness and performance in concurrent workloads. Both 'reg' and 'clocks' properties are optional. If either is missing, QoS configuration will be skipped. This behavior is controlled by the 'qos_requires_clocks' flag in the driver, which ensures that QoS configuration is bypassed when required clocks are not defined.

2025-10-30PM: hibernate: add sysfs interface for hibernate_compression_threadsXueqin Luo1-0/+16
Add a sysfs attribute `/sys/power/hibernate_compression_threads` to allow runtime configuration of the number of threads used for compressing and decompressing hibernation images. The new sysfs interface enables dynamic adjustment at runtime: # cat /sys/power/hibernate_compression_threads 3 # echo 4 > /sys/power/hibernate_compression_threads This change provides greater flexibility for debugging and performance tuning of hibernation without requiring a reboot.

2025-10-30PM: hibernate: make compression threads configurableXueqin Luo1-0/+10
The number of compression/decompression threads has a direct impact on hibernate image generation and resume latency. Using more threads can reduce overall resume time, but on systems with fewer CPU cores it may also introduce contention and reduce efficiency. Performance was evaluated on an 8-core ARM system, averaged over 10 runs: Threads Hibernate(s) Resume(s) -------------------------------- 3 12.14 18.86 4 12.28 17.48 5 11.09 16.77 6 11.08 16.44 With 5–6 threads, resume latency improves by approximately 12% compared to the default 3-thread configuration, with negligible impact on hibernate time. Introduce a new kernel parameter `hibernate_compression_threads=` that allows users and integrators to tune the number of compression/decompression threads at boot. This provides a way to balance performance and CPU utilization across a wide range of hardware without recompiling the kernel.

2025-10-30net/smc: handle -ENOMEM from smc_wr_alloc_link_mem gracefullyHalil Pasic1-2/+6
Currently if a -ENOMEM from smc_wr_alloc_link_mem() is handled by giving up and going the way of a TCP fallback. This was reasonable before the sizes of the allocations there were compile time constants and reasonably small. But now those are actually configurable. So instead of giving up, keep retrying with half of the requested size unless we dip below the old static sizes -- then give up! In terms of numbers that means we give up when it is certain that we at best would end up allocating less than 16 send WR buffers or less than 48 recv WR buffers. This is to avoid regressions due to having fewer buffers compared the static values of the past. Please note that SMC-R is supposed to be an optimisation over TCP, and falling back to TCP is superior to establishing an SMC connection that is going to perform worse. If the memory allocation fails (and we propagate -ENOMEM), we fall back to TCP. Preserve (modulo truncation) the ratio of send/recv WR buffer counts.

2025-10-30net/smc: make wr buffer count configurableHalil Pasic1-0/+36
Think SMC_WR_BUF_CNT_SEND := SMC_WR_BUF_CNT used in send context and SMC_WR_BUF_CNT_RECV := 3 * SMC_WR_BUF_CNT used in recv context. Those get replaced with lgr->max_send_wr and lgr->max_recv_wr respective. Please note that although with the default sysctl values qp_attr.cap.max_send_wr == qp_attr.cap.max_recv_wr is maintained but can not be assumed to be generally true any more. I see no downside to that, but my confidence level is rather modest.
