Pull SoC devicetree updates from Arnd Bergmann: "There is new support for additional on-chip devices on Apple, Mediatek, Renesas, Rockchip, Samsung, Google, TI, ST, Nvidia and Amlogic devices. The Arm Morello reference platform gets a devicetree for booting in normal aarch64 mode. The hardware supports experimental CHERI support, which requires a modified kernel. The AMD (formerly Xilinx) Versal NET SoC gets added, this is a combined FPGA with Cortex-A78 CPUs in a SoC. Six new ST STM32MP2 SoC variants are added. Like the earlier STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are based on one or two Cortex-A35 cores but each feature a different set of I/O devices. Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU cores Apple T2 is the baseboard management controller on earlier Intel CPU based Macs, with 16 models now gaining initial support. All the above come with dts files for the reference boards. In addition, these boards are added for the SoCs that are already supported: - The Milk-V Jupiter board based on SpacemiT K1/M1 - NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC - Three boards based on 32-bit stm32mp1 - 11 distinct board variants from Toradex and one from Variscite, all based on i.MX6 - Google Pixel Pro 6 phone based on gs101 (Tensor) - Three additional variants of the i.MX8MP based "Skov" board - A second variant of the i.MX95 EVK board - Two boards based on Renesas SoCs - Four boards based the Rockchip RK35xx series, plus the RK3588 'MNT Reform 2' laptop" * tag 'soc-dt-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (538 commits) arm64: dts: Add gpio_intc node for Amlogic A5 SoCs arm64: dts: Add gpio_intc node for Amlogic A4 SoCs arm64: dts: hi3660: Add property for fixing CPUIdle arm64: dts: rockchip: remove ethm0_clk0_25m_out from Sige5 gmac0 arm64: dts: marvell: Use preferred node names for "simple-bus" arm64: dts: marvell: Drop unused CP11X_TYPE define arm64: dts: marvell: Move arch timer and pmu nodes to top-level arm64: dts: rockchip: Fix PWM pinctrl names arm64: dts: rockchip: fix RK3576 SCMI clock IDs dt-bindings: clock: rk3576: add SCMI clocks arm64: dts: rockchip: Fix pcie reset gpio on Orange Pi 5 Max arm64: dts: amd/seattle: Drop undocumented "spi-controller" properties arm64: dts: amd/seattle: Fix bus, mmc, and ethernet node names arm64: dts: amd/seattle: Move and simplify fixed clocks arm64: dts: amd/seattle: Base Overdrive B1 on top of B0 version arm64: dts: rockchip: Enable HDMI audio output for ArmSoM Sige7 arm64: dts: rockchip: Enable onboard eMMC on Radxa E20C arm64: dts: rockchip: Add SDHCI controller for RK3528 arm64: dts: rockchip: Remove bluetooth node from rock-3a arm64: dts: rockchip: Move rk356x scmi SHMEM to reserved memory ...

2025-03-27tpm, tpm_tis: Workaround failed command reception on Infineon devicesJonathan McDowell
Some Infineon devices have a issue where the status register will get stuck with a quick REQUEST_USE / COMMAND_READY sequence. This is not simply a matter of requiring a longer timeout; the work around is to retry the command submission. Add appropriate logic to do this in the send path. This is fixed in later firmware revisions, but those are not always available, and cannot generally be easily updated from outside a firmware environment. Testing has been performed with a simple repeated loop of doing a TPM2_CC_GET_CAPABILITY for TPM_CAP_PROP_MANUFACTURER using the Go code at: https://the.earth.li/~noodles/tpm-stuff/timeout-reproducer-simple.go It can take several hours to reproduce, and several million operations.

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.

2025-03-26mailbox: pcc: Always map the shared memory communication addressSudeep Holla
Currently the shared memory communication address was mapped by the mailbox client drivers leading to all sorts of inconsistencies. It also has resulted in the inconsistent attributes used while mapping the shared memory regions. In order to remove/eliminate any issues, let us ensures the shared memory address is always mapped and unmapped when the PCC channels are requested and release. We need to map them as the ACPI PCCT associates these shared memory with each channel subspace and may need use the status or the flags in the headers of those shared memory communication address regions to manage the transport/channel. Note, until all the drivers using PCC start using this mapped shmem, there might be double mapping of the shared memory address. This shouldn't have any impact on existing mbox client drivers. Since there are no users of pcc_chan_ioremap() and also it is mapped by default, we can stop exporting it and merge the functionality into pcc_mbox_request_channel().

2025-03-26mailbox: pcc: Drop unnecessary endianness conversion of pcc_hdr.flagsSudeep Holla
The Sparse static checker flags a type mismatch warning related to endianness conversion: | warning: incorrect type in argument 1 (different base types) | expected restricted __le32 const [usertype] *p | got unsigned int * This is because an explicit endianness conversion (le32_to_cpu()) was applied unnecessarily to a pcc_hdr.flags field that is already in little-endian format. The PCC driver is only enabled on little-endian kernels due to its dependency on ACPI and EFI, making the explicit conversion unnecessary. The redundant conversion occurs in pcc_chan_check_and_ack() for the pcc_hdr.flags field. Drop this unnecessary endianness conversion of pcc_hdr.flags. Also drop the redundant PCC_ACK_FLAG_MASK definition and use the more appropriate and already defined PCC_CMD_COMPLETION_NOTIFY.

2025-03-26Merge patch series "riscv: Relocatable NOMMU kernels"Palmer Dabbelt
Samuel Holland <samuel.holland@sifive.com> says: Currently, RISC-V NOMMU kernels are linked at CONFIG_PAGE_OFFSET, and since they are not relocatable, must be loaded at this address as well. CONFIG_PAGE_OFFSET is not a user-visible Kconfig option, so its value is not obvious, and users must patch the kernel source if they want to load it at a different address. Make NOMMU kernels more portable by making them relocatable by default. This allows a single kernel binary to work when loaded at any address. * b4-shazam-merge: riscv: Remove CONFIG_PAGE_OFFSET riscv: Support CONFIG_RELOCATABLE on riscv32 asm-generic: Always define Elf_Rel and Elf_Rela riscv: Support CONFIG_RELOCATABLE on NOMMU riscv: Allow NOMMU kernels to access all of RAM riscv: Remove duplicate CONFIG_PAGE_OFFSET definition Link: https://lore.kernel.org/r/20241026171441.3047904-1-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

2025-03-26drm/gem: Change locked/unlocked postfix of drm_gem_v/unmap() function namesDmitry Osipenko
Make drm/gem API function names consistent by having locked function use the _locked postfix in the name, while the unlocked variants don't use the _unlocked postfix. Rename drm_gem_v/unmap() function names to make them consistent with the rest of the API functions.
