2024-04-30net: dsa: mt7530: do not set MT7530_P5_DIS when PHY muxing is being usedArınç ÜNAL
DSA initalises the ds->num_ports amount of ports in dsa_switch_touch_ports(). When the PHY muxing feature is in use, port 5 won't be defined in the device tree. Because of this, the type member of the dsa_port structure for this port will be assigned DSA_PORT_TYPE_UNUSED. The dsa_port_setup() function calls ds->ops->port_disable() when the port type is DSA_PORT_TYPE_UNUSED. The MT7530_P5_DIS bit is unset in mt7530_setup() when PHY muxing is being used. mt7530_port_disable() which is assigned to ds->ops->port_disable() is called afterwards. Currently, mt7530_port_disable() sets MT7530_P5_DIS which breaks network connectivity when PHY muxing is being used. Therefore, do not set MT7530_P5_DIS when PHY muxing is being used.

2024-04-30virtio-net: support queue statXuan Zhuo
To enhance functionality, we now support reporting statistics through the netdev-generic netlink (netdev-genl) queue stats interface. However, this does not extend to all statistics, so a new field, qstat_offset, has been introduced. This field determines which statistics should be reported via netdev-genl queue stats. Given that queue stats are retrieved individually per queue, it's necessary for the virtnet_get_hw_stats() function to be capable of fetching statistics for a specific queue. As the document https://docs.kernel.org/next/networking/statistics.html#notes-for-driver-authors We should not duplicate the stats which get reported via the netlink API in ethtool. If the stats are for queue stat, that will not be reported by ethtool -S. python3 ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml --dump qstats-get --json '{"scope": "queue"}' [{'ifindex': 2, 'queue-id': 0, 'queue-type': 'rx', 'rx-bytes': 157844011, 'rx-csum-bad': 0, 'rx-csum-none': 0, 'rx-csum-unnecessary': 2195386, 'rx-hw-drop-overruns': 0, 'rx-hw-drop-ratelimits': 0, 'rx-hw-drops': 12964, 'rx-packets': 598929}, {'ifindex': 2, 'queue-id': 0, 'queue-type': 'tx', 'tx-bytes': 1938511, 'tx-csum-none': 0, 'tx-hw-drop-errors': 0, 'tx-hw-drop-ratelimits': 0, 'tx-hw-drops': 0, 'tx-needs-csum': 61263, 'tx-packets': 15515}] Signed-off-by: Xuan Zhuo <xuanzhuo@linux.alibaba.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

https://anongit.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - drm/i915/guc: Use context hints for GT frequency Allow user to provide a low latency context hint. When set, KMD sends a hint to GuC which results in special handling for this context. SLPC will ramp the GT frequency aggressively every time it switches to this context. The down freq threshold will also be lower so GuC will ramp down the GT freq for this context more slowly. We also disable waitboost for this context as that will interfere with the strategy. We need to enable the use of SLPC Compute strategy during init, but it will apply only to contexts that set this bit during context creation. Userland can check whether this feature is supported using a new param- I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission enabled platforms as they use SLPC for frequency management. The Mesa usage model for this flag is here - https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint - drm/i915/gt: Enable only one CCS for compute workload Enable only one CCS engine by default with all the compute sices allocated to it. While generating the list of UABI engines to be exposed to the user, exclude any additional CCS engines beyond the first instance *** NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by default to mitigate a hardware bug. All the EUs will still remain usable, and all the userspace drivers have been confirmed to be able to dynamically detect the change in number of CCS engines and adjust. For the smaller percent of applications that get perf benefit from letting the userspace driver dispatch across all 4 CCS engines we will be introducing a sysfs control as a later patch to choose 4 CCS each with 25% EUs (or 50% if 2 CCS).

Commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host command and irq disable") re-ordered the resume sequence. Before that change, cros_ec resume sequence is: 1) Enable IRQ 2) Send resume event 3) Handle events during suspend After commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host command and irq disable"), cros_ec resume sequence is: 1) Enable IRQ 2) Handle events during suspend 3) Send resume event. This re-ordering leads to delayed handling of any events queued between items 2) and 3) with the updated sequence. Also in certain platforms, EC skips triggering interrupt for certain events eg. mkbp events until the resume event is received. Such events are stuck in the host event queue indefinitely. This change puts back the original order to avoid any delay in handling the pending events.

2024-04-30iommu/vt-d: Enable posted mode for device MSIsJacob Pan
With posted MSI feature enabled on the CPU side, iommu interrupt remapping table entries (IRTEs) for device MSI/x can be allocated, activated, and programed in posted mode. This means that IRTEs are linked with their respective PIDs of the target CPU. Handlers for the posted MSI notification vector will de-multiplex device MSI handlers. CPU notifications are coalesced if interrupts arrive at a high frequency. Posted interrupts are only used for device MSI and not for legacy devices (IO/APIC, HPET). Introduce a new irq_chip for posted MSIs, which has a dummy irq_ack() callback as EOI is performed in the notification handler once. When posted MSI is enabled, MSI domain/chip hierarchy will look like this example: domain: IR-PCI-MSIX-0000:50:00.0-12 hwirq: 0x29 chip: IR-PCI-MSIX-0000:50:00.0 flags: 0x430 IRQCHIP_SKIP_SET_WAKE IRQCHIP_ONESHOT_SAFE parent: domain: INTEL-IR-10-13 hwirq: 0x2d0000 chip: INTEL-IR-POST flags: 0x0 parent: domain: VECTOR hwirq: 0x77 chip: APIC Suggested-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20240423174114.526704-13-jacob.jun.pan@linux.intel.com

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.10 1. Support for handling notification pending interrupt(NPI) The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: - A guest/VM running under a hypervisor(normal world usecase) - An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase) Also, when the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. These changes include skipping of creation of notification bitmaps, some refactoring around schedule receiver interrupt(SRI) handling and addition of support for NPI. 2. Support for FF-A indirect messaging The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint and inform the scheduler that the receiver endpoint must be run. Apart from these two main features, there is an optimisation to avoid queuing of a work when already running on the worker queue. * tag 'ffa-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Avoid queuing work when running on the worker queue firmware: arm_ffa: Fix memory corruption in ffa_msg_send2() firmware: arm_ffa: Add support for FFA_MSG_SEND2 firmware: arm_ffa: Stash the partition properties for query purposes firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support firmware: arm_ffa: Skip creation of the notification bitmaps Link: https://lore.kernel.org/r/20240426105051.1527016-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/20240426105031.1526987-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

https://git.linaro.org/people/jens.wiklander/linux-tee into soc/drivers TEE driver for Trusted Services This introduces a TEE driver for Trusted Services [1]. Trusted Services is a TrustedFirmware.org project that provides a framework for developing and deploying device Root of Trust services in FF-A [2] Secure Partitions. The project hosts the reference implementation of Arm Platform Security Architecture [3] for Arm A-profile devices. The FF-A Secure Partitions are accessible through the FF-A driver in Linux. However, the FF-A driver doesn't have a user space interface so user space clients currently cannot access Trusted Services. The goal of this TEE driver is to bridge this gap and make Trusted Services functionality accessible from user space.
