platform/x86: intel_pmc_ipc: add option to build without ACPI

2025-04-07T11:50:43Z

Introduce a configuration option that allows users to build the intel_pmc_ipc driver without ACPI support. This is useful for systems where ACPI is not available or desired. Based on the discussion from the patch [1], it was necessary to provide this option to accommodate specific use cases.

As a driver opt-in protect queue operations and (in due course) ethtool operations with the instance lock and not RTNL lock. - Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance. - Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring. - Optimize MPTCP performance in single subflow mode by 29%. - Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x. - Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock. Bring an additional 229% improvement by tweaking hash distribution. - Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%. - Avoid skb_clone() dance in ping_rcv() to improve performance under ping flood. - Avoid FIB lookup in netfilter if socket is available, 20% perf win. - Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles. There are up to 4 namespace roles but we used to have just 2 netns pointer arguments, interpreted differently based on context. - Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access. - Add a new sysctl and sockopt for capping max retransmit timeout in TCP. - Support masking port and DSCP in routing rule matches. - Support dumping IPv4 multicast addresses with RTM_GETMULTICAST. - Support specifying at what time packet should be sent on AF_XDP sockets. - Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users. - Add Netlink YAML spec for WiFi (nl80211) and conntrack. - Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module. - Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging. - Allow users to specify source port range for GENEVE tunnels. - netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata Driver API: - Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers.

arch: x86: add IPC mailbox accessor function and add SoC register access

- Exports intel_pmc_ipc() for host access to the PMC IPC mailbox - Enables the host to access specific SoC registers through the PMC firmware using IPC commands. This access method is necessary for registers that are not available through direct Memory-Mapped I/O (MMIO), which is used for other accessible parts of the PMC. Signed-off-by: David E.

platform: arm64: add Huawei Matebook E Go EC driver

2025-03-03T08:55:36Z

There are three variants of which Huawei released the first two simultaneously. Huawei Matebook E Go LTE(sc8180x), codename seems to be gaokun2. Huawei Matebook E Go(sc8280xp@3.0GHz), codename must be gaokun3. (see [1]) Huawei Matebook E Go 2023(sc8280xp@2.69GHz), codename should be also gaokun3. Adding support for the latter two variants for now, this driver should also work for the sc8180x variant according to acpi table files, but I don't have the device to test yet. Different from other Qualcomm Snapdragon sc8280xp based machines, the Huawei Matebook E Go uses an embedded controller while others use a system called PMIC GLink. This embedded controller can be used to perform a set of various functions, including, but not limited to: - Battery and charger monitoring; - Charge control and smart charge; - Fn_lock settings; - Tablet lid status; - Temperature sensors; - USB Type-C notifications (ports orientation, DP alt mode HPD); - USB Type-C PD (according to observation, up to 48w). Add a driver for the EC which creates devices for UCSI and power supply devices. This driver is inspired by the following drivers: drivers/platform/arm64/acer-aspire1-ec.c drivers/platform/arm64/lenovo-yoga-c630.c drivers/platform/x86/huawei-wmi.c Also thanks for reviewers' working. They have made this patch improve a lot.
