2023-12-22Input: soc_button_array - add mapping for airplane mode buttonChristoffer Sandberg
This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3. While it is physically a key it behaves more like a switch, sending a key down on first press and a key up on 2nd press. Therefor the switch event is used here. Besides this behaviour it uses the HID usage-id 0xc6 (Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but since neither 0xc6 nor 0xc8 are currently implemented at all in soc_button_array this not to standard behaviour is not put behind a quirk for the moment.

2023-12-23drm: Don't unref the same fb many times by mistake due to deadlock handlingVille Syrjälä
If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end result is that the fb will (eventually) end up being freed while it's still in use. Reset fb to NULL once we've unreffed it to avoid doing it again until we've done another fb lookup. This turned out to be pretty easy to hit on a DG2 when doing async flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I saw that drm_closefb() simply got stuck in a busy loop while walking the framebuffer list. Fortunately I was able to convince it to oops instead, and from there it was easier to track down the culprit.

2023-12-23dpaa2-switch: cleanup the egress flood of an unused FDBIoana Ciornei
In case a DPAA2 switch interface joins a bridge, the FDB used on the port will be changed to the one associated with the bridge. What this means exactly is that any VLAN installed on the port will need to be removed and then installed back so that it points to the new FDB. Once this is done, the previous FDB will become unused (no VLAN to point to it). Even though no traffic will reach this FDB, it's best to just cleanup the state of the FDB by zeroing its egress flood domain.

2023-12-23dpaa2-switch: do not clear any interrupts automaticallyIoana Ciornei
The DPSW object has multiple event sources multiplexed over the same IRQ. The driver has the capability to configure only some of these events to trigger the IRQ. The dpsw_get_irq_status() can clear events automatically based on the value stored in the 'status' variable passed to it. We don't want that to happen because we could get into a situation when we are clearing more events than we actually handled. Just resort to manually clearing the events that we handled. Also, since status is not used on the out path we remove its initialization to zero. This change does not have a user-visible effect because the dpaa2-switch driver enables and handles all the DPSW events which exist at the moment.

2023-12-23dpaa2-switch: add ENDPOINT_CHANGED to the irq_maskIoana Ciornei
Commit 84cba72956fd ("dpaa2-switch: integrate the MAC endpoint support") added support for MAC endpoints in the dpaa2-switch driver but omitted to add the ENDPOINT_CHANGED irq to the list of interrupt sources. Fix this by extending the list of events which can raise an interrupt by extending the mask passed to the dpsw_set_irq_mask() firmware API. There is no user visible impact even without this patch since whenever a switch interface is connected/disconnected from an endpoint both events are set (LINK_CHANGED and ENDPOINT_CHANGED) and, luckily, the LINK_CHANGED event could actually raise the interrupt and thus get the MAC/PHY SW configuration started. Even with this, it's better to just not rely on undocumented firmware behavior which can change.

2023-12-23net: ethernet: ti: am65-cpsw: add mqprio qdisc offload in channel modeGrygorii Strashko
This patch adds MQPRIO Qdisc offload in full 'channel' mode which allows not only setting up pri:tc mapping, but also configuring TX shapers (rate-limiting) on external port FIFOs. The MQPRIO Qdisc offload is expected to work with or without VLAN/priority tagged packets. The CPSW external Port FIFO has 8 Priority queues. The rate-limit can be set for each of these priority queues. Which Priority queue a packet is assigned to depends on PN_REG_TX_PRI_MAP register which maps header priority to switch priority. The header priority of a packet is assigned via the RX_PRI_MAP_REG which maps packet priority to header priority. The packet priority is either the VLAN priority (for VLAN tagged packets) or the thread/channel offset. For simplicity, we assign the same priority queue to all queues of a Traffic Class so it can be rate-limited correctly. Configuration example: ethtool -L eth1 tx 5 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \ map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 1@1 1@2 hw 1 mode channel \ shaper bw_rlimit min_rate 0 100mbit 200mbit max_rate 0 101mbit 202mbit tc qdisc replace dev eth2 handle 100: parent root mqprio num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 1@0 hw 1 ip link add link eth1 name eth1.100 type vlan id 100 ip link set eth1.100 type vlan egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7 In the above example two ports share the same TX CPPI queue 0 for low priority traffic. 3 traffic classes are defined for eth1 and mapped to: TC0 - low priority, TX CPPI queue 0 -> ext Port 1 fifo0, no rate limit TC1 - prio 2, TX CPPI queue 1 -> ext Port 1 fifo1, CIR=100Mbit/s, EIR=1Mbit/s TC2 - prio 3, TX CPPI queue 2 -> ext Port 1 fifo2, CIR=200Mbit/s, EIR=2Mbit/s Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Roger Quadros <rogerq@kernel.org> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

We will use this Kconfig option to not only enable TAS/EST offload but also other QoS features like Multiqueue priority descriptors and MAC-Merge/Frame Preemption. TI_AM65_CPSW_QOS seems a more appropriate Kconfig option name than TI_AM65_CPSW_TAS.

2023-12-22cxl: Check qos_class validity on memdev probeDave Jiang
Add a check to make sure the qos_class for the device will match one of the root decoders qos_class. If no match is found, then the qos_class for the device is set to invalid. Also add a check to ensure that the device's host bridge matches to one of the root decoder's downstream targets.

2023-12-22cxl: Export sysfs attributes for memory device QoS classDave Jiang
Export qos_class sysfs attributes for the CXL memory device. The QoS clas should show up as /sys/bus/cxl/devices/memX/ram/qos_class for the volatile partition and /sys/bus/cxl/devices/memX/pmem/qos_class for the persistent partition. The QTG ID is retrieved via _DSM after supplying the calculated bandwidth and latency for the entire CXL path from device to the CPU. This ID is used to match up to the root decoder QoS class to determine which CFMWS the memory range of a hotplugged CXL mem device should be assigned under. While there may be multiple DSMAS exported by the device CDAT, the driver will only expose the first QTG ID per partition in sysfs for now. In the future when multiple QTG IDs are necessary, they can be exposed.

2023-12-22cxl: Store QTG IDs and related info to the CXL memory device contextDave Jiang
Once the QTG ID _DSM is executed successfully, the QTG ID is retrieved from the return package. Create a list of entries in the cxl_memdev context and store the QTG ID as qos_class token and the associated DPA range. This information can be exposed to user space via sysfs in order to help region setup for hot-plugged CXL memory devices.
