2025-10-31dt-bindings: interconnect: add reg and clocks properties to enable QoS on ↵Odelu Kukatla
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.

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 Luo
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 Pasic
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.

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.

2025-10-29ipv6: icmp: Add RFC 5837 supportIdo Schimmel
Add the ability to append the incoming IP interface information to ICMPv6 error messages in accordance with RFC 5837 and RFC 4884. This is required for more meaningful traceroute results in unnumbered networks. The feature is disabled by default and controlled via a new sysctl ("net.ipv6.icmp.errors_extension_mask") which accepts a bitmask of ICMP extensions to append to ICMP error messages. Currently, only a single value is supported, but the interface and the implementation should be able to support more extensions, if needed. Clone the skb and copy the relevant data portions before modifying the skb as the caller of icmp6_send() still owns the skb after the function returns. This should be fine since by default ICMP error messages are rate limited to 1000 per second and no more than 1 per second per specific host. Trim or pad the packet to 128 bytes before appending the ICMP extension structure in order to be compatible with legacy applications that assume that the ICMP extension structure always starts at this offset (the minimum length specified by RFC 4884). Since commit 20e1954fe238 ("ipv6: RFC 4884 partial support for SIT/GRE tunnels") it is possible for icmp6_send() to be called with an skb that already contains ICMP extensions. This can happen when we receive an ICMPv4 message with extensions from a tunnel and translate it to an ICMPv6 message towards an IPv6 host in the overlay network. I could not find an RFC that supports this behavior, but it makes sense to not overwrite the original extensions that were appended to the packet. Therefore, avoid appending extensions if the length field in the provided ICMPv6 header is already filled. Export netdev_copy_name() using EXPORT_IPV6_MOD_GPL() to make it available to IPv6 when it is built as a module.

Along with the MIPI-DSI panel, these devices also have an in-built LED backlight device and a touchscreen, all packed together in a single chip. Also, add compatibles for supported panels - TD4101 and TD4300. Both have the '-panel' suffix so as to remove any ambiguity between the panel and touchscreen chips.

2025-10-29Documentation: intel_pstate: fix duplicate hyperlink target errorsSwaraj Gaikwad
Fix reST warnings in Documentation/admin-guide/pm/intel_pstate.rst caused by missing explicit hyperlink labels for section titles. Before this change, the following errors were printed during `make htmldocs`: Documentation/admin-guide/pm/intel_pstate.rst:401: ERROR: Indirect hyperlink target (id="id6") refers to target "passive mode", which is a duplicate, and cannot be used as a unique reference. Documentation/admin-guide/pm/intel_pstate.rst:517: ERROR: Indirect hyperlink target (id="id9") refers to target "active mode", which is a duplicate, and cannot be used as a unique reference. Documentation/admin-guide/pm/intel_pstate.rst:611: ERROR: Indirect hyperlink target (id="id15") refers to target "global attributes", which is a duplicate, and cannot be used as a unique reference. ERROR: Duplicate target name, cannot be used as a unique reference: "passive mode", "active mode", "global attributes". These errors occurred because the sections "Active Mode", "Active Mode With HWP", "Passive Mode", and "Global Attributes" did not define explicit hyperlink labels. As a result, Sphinx auto-generated duplicate anchors when the same titles appeared multiple times within the document. Because of this, the generated HTML documentation contained broken references such as: `active mode <Active Mode_>`_ `passive mode <Passive Mode_>`_ `global attributes <Global Attributes_>`_ This patch adds explicit hyperlink labels for the affected sections, ensuring all references are unique and correctly resolved. After applying this patch, `make htmldocs` completes without any warnings, and all hyperlinks in intel_pstate.html render properly.
