The first patch implements port state configuration, which is required for bridge functionality. STP frames are not forwarded at this moment. BPDU frames are only forwarded from/to the PI/SI interface. For more information, see chapter 2.7.1 (CPU Forwarding) in the datasheet. Patches 2, 7-9 and 11 provide a basic implementation of tag_8021q functionality with QinQ support, without VLAN filtering in the bridge and simple VLAN awareness in VLAN filtering mode. Patches 3-6 came from Vladimir Oltean. They prepare for making tag8021q more common. VSC73XX uses very similar tag recognition, and some code from tag_sja1105 could be moved to tag_8021q for common use. Patch 10 is preparation for use tag_8021q bridge functions as generic implementation of the 'ds->ops->port_bridge_*()'. Patch 12 is required to avoid problem with learning on standalone ports.

This patch is a simple implementation of 802.1q tagging in the vsc73xx driver. Currently, devices with DSA_TAG_PROTO_NONE are not functional. The VSC73XX family doesn't provide any tag support for external Ethernet ports. The only option available is VLAN-based tagging, which requires constant hardware VLAN filtering. While the VSC73XX family supports provider bridging, it only supports QinQ without full implementation of 802.1AD. This means it only allows the doubled 0x8100 TPID. In the simple port mode, QinQ is enabled to preserve forwarding of VLAN-tagged frames.

tag_sja1105 has a wrapper over dsa_8021q_rcv(): sja1105_vlan_rcv(), which determines whether the packet came from a bridge with vlan_filtering=1 (the case resolved via dsa_find_designated_bridge_port_by_vid()), or if it contains a tag_8021q header. Looking at a new tagger implementation for vsc73xx, based also on tag_8021q, it is becoming clear that the logic is needed there as well. So instead of forcing each tagger to wrap around dsa_8021q_rcv(), let's merge the logic into the core.

2024-07-15net: dsa: tag_sja1105: absorb logic for not overwriting precise info into ↵Vladimir Oltean
dsa_8021q_rcv() In both sja1105_rcv() and sja1110_rcv(), we may have precise source port information coming from parallel hardware mechanisms, in addition to the tag_8021q header. Only sja1105_rcv() has extra logic to not overwrite that precise info with what's present in the VLAN tag. This is because sja1110_rcv() gets by, by having a reversed set of checks when assigning skb->dev. When the source port is imprecise (vbid >=1), source_port and switch_id will be set to zeroes by dsa_8021q_rcv(), which might be problematic. But by checking for vbid >= 1 first, sja1110_rcv() fends that off. We would like to make more code common between sja1105_rcv() and sja1110_rcv(), and for that, we need to make sure that sja1110_rcv() also goes through the precise source port preservation logic.

There were several undocumented fields in structs irq_domain_ops and irq_domain_info. Document them. irq_domain_ops::revmap_size contained "[]" in the description, which is not allowed in sphinx. Remove that. Finally, plug the whole header (irqdomain.h) into genericirq.rst, so that the docs is autogenerated and hyperlinks to these structure are created.

2024-07-15genirq: Set IRQF_COND_ONESHOT in request_irq()Rafael J. Wysocki
The callers of request_irq() don't care about IRQF_ONESHOT because they don't provide threaded handlers, but if they happen to share the IRQ with the ACPI SCI, which has a threaded handler and sets IRQF_ONESHOT, request_irq() will fail for them due to a flags mismatch. Address this by making request_irq() add IRQF_COND_ONESHOT to the flags passed to request_threaded_irq() for all of its callers.

The power domain is automatically activated from clk_prepare(). However, on certain platforms like i.MX8QM and i.MX8QXP, the power-on handling invokes sleeping functions, which triggers the 'scheduling while atomic' bug in the context switch path during device probing: BUG: scheduling while atomic: kworker/u13:1/48/0x00000002 Call trace: __schedule_bug+0x54/0x6c __schedule+0x7f0/0xa94 schedule+0x5c/0xc4 schedule_preempt_disabled+0x24/0x40 __mutex_lock.constprop.0+0x2c0/0x540 __mutex_lock_slowpath+0x14/0x20 mutex_lock+0x48/0x54 clk_prepare_lock+0x44/0xa0 clk_prepare+0x20/0x44 imx_irqsteer_resume+0x28/0xe0 pm_generic_runtime_resume+0x2c/0x44 __genpd_runtime_resume+0x30/0x80 genpd_runtime_resume+0xc8/0x2c0 __rpm_callback+0x48/0x1d8 rpm_callback+0x6c/0x78 rpm_resume+0x490/0x6b4 __pm_runtime_resume+0x50/0x94 irq_chip_pm_get+0x2c/0xa0 __irq_do_set_handler+0x178/0x24c irq_set_chained_handler_and_data+0x60/0xa4 mxc_gpio_probe+0x160/0x4b0 Cure this by implementing the irq_bus_lock/sync_unlock() interrupt chip callbacks and handle power management in them as they are invoked from non-atomic context.

2024-07-15irqchip/bcm2835: Enable SKIP_SET_WAKE and MASK_ON_SUSPENDStefan Wahren
The BCM2835 ARMCTRL interrupt controller doesn't provide any facility to configure the wakeup sources. That's the reason why the driver lacks the irq_set_wake() callback for the interrupt chip. But this prevent to properly enter power management states like "suspend to idle". Enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND so the interrupt suspend logic can handle the chip correctly.

2024-07-15irqchip/gic-v4: Substitute vmovp_lock for a per-VM lockMarc Zyngier
vmovp_lock is abused in a number of cases to serialise updates to vlpi_count[] and deal with map/unmap of a VM to ITSs. Instead, provide a per-VM lock and revisit the use of vlpi_count[] so that it is always wrapped in this per-VM vmapp_lock. This reduces the potential contention on a concurrent VMOVP command, and paves the way for subsequent VPE locking that holding vmovp_lock actively prevents due to the lock ordering.

2024-07-15net: ti: icssg-prueth: Split out common object into moduleMD Danish Anwar
icssg_prueth.c and icssg_prueth_sr1.c drivers use multiple common .c files. These common objects are getting added to multiple modules. As a result when both drivers are enabled in .config, below warning is seen. drivers/net/ethernet/ti/Makefile: icssg/icssg_common.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_classifier.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_config.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_mii_cfg.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_stats.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 drivers/net/ethernet/ti/Makefile: icssg/icssg_ethtool.o is added to multiple modules: icssg-prueth icssg-prueth-sr1 Fix this by building a new module (icssg.o) for all the common objects. Both the driver can then depend on this common module. Some APIs being exported have emac_ as the prefix which may result into confusion with other existing APIs with emac_ prefix, to avoid confusion, rename the APIs being exported with emac_ to icssg_ prefix. This also fixes below error seen when both drivers are built. ERROR: modpost: "icssg_queue_pop" [drivers/net/ethernet/ti/icssg-prueth-sr1.ko] undefined!

2024-07-15iommufd: Put constants for all the uAPI enumsJason Gunthorpe
Relying on position in the enum makes it subtly harder when doing merge resolutions or backporting as it is easy to grab a patch and not notice it is a uAPI change with a differently ordered enum. This may become a bigger problem in next cycles when iommu_hwpt_invalidate_data_type and other per-driver enums have patches flowing through different trees. So lets start including constants for all the uAPI enums to make this safer. No functional change.
