2023-07-11scsi: storvsc: Handle SRB status value 0x30Michael Kelley
In response to a disk I/O request, Hyper-V has been observed to return SRB status value 0x30. This indicates the request was not processed by Hyper-V because low memory conditions on the host caused an internal error. The 0x30 status is not recognized by storvsc, so the I/O operation is not flagged as an error. The request is treated as if it completed normally but with zero data transferred, causing a flood of retries. Add a definition for this SRB status value and handle it like other error statuses from the Hyper-V host.

2023-07-11drm/client: Send hotplug event after registering a clientThomas Zimmermann
Generate a hotplug event after registering a client to allow the client to configure its display. Remove the hotplug calls from the existing clients for fbdev emulation. This change fixes a concurrency bug between registering a client and receiving events from the DRM core. The bug is present in the fbdev emulation of all drivers. The fbdev emulation currently generates a hotplug event before registering the client to the device. For each new output, the DRM core sends an additional hotplug event to each registered client. If the DRM core detects first output between sending the artificial hotplug and registering the device, the output's hotplug event gets lost. If this is the first output, the fbdev console display remains dark. This has been observed with amdgpu and fbdev-generic. Fix this by adding hotplug generation directly to the client's register helper drm_client_register(). Registering the client and receiving events are serialized by struct drm_device.clientlist_mutex. So an output is either configured by the initial hotplug event, or the client has already been registered. The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper: generic: Call drm_client_add() after setup is done"), in which adding a client and receiving a hotplug event switched order. It was hidden, as most hardware and drivers have at least on static output configured. Other drivers didn't use the internal DRM client or still had struct drm_mode_config_funcs.output_poll_changed set. That callback handled hotplug events as well. After not setting the callback in amdgpu in commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct drm_driver.output_poll_changed"), amdgpu did not show a framebuffer console if output events got lost. The bug got copy-pasted from fbdev-generic into the other fbdev emulation.

2023-07-11net: fec: increase the size of tx ring and update tx_wake_thresholdWei Fang
When the XDP feature is enabled and with heavy XDP frames to be transmitted, there is a considerable probability that available tx BDs are insufficient. This will lead to some XDP frames to be discarded and the "NOT enough BD for SG!" error log will appear in the console (as shown below). [ 160.013112] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.023116] fec 30be0000.ethernet eth0: NOT enough BD for SG! [ 160.028926] fec 30be0000.ethernet eth0: NOT enough BD for SG!

In the case of heavy XDP traffic, sometimes the speed of recycling tx BDs may be slower than the speed of sending XDP frames. There may be several specific reasons, such as the interrupt is not responsed in time, the efficiency of the NAPI callback function is too low due to all the queues (tx queues and rx queues) share the same NAPI, and so on. After trying various methods, I think that increase the size of tx BD ring is simple and effective. Maybe the best resolution is that allocate NAPI for each queue to improve the efficiency of the NAPI callback, but this change is a bit big and I didn't try this method. Perheps this method will be implemented in a future patch. This patch also updates the tx_wake_threshold of tx ring which is related to the size of tx ring in the previous logic. Otherwise, the tx_wake_threshold will be too high (403 BDs), which is more likely to impact the slow path in the case of heavy XDP traffic, because XDP path and slow path share the tx BD rings. According to Jakub's suggestion, the tx_wake_threshold is at least equal to tx_stop_threshold + 2 * MAX_SKB_FRAGS, if a queue of hundreds of entries is overflowing, we should be able to apply a hysteresis of a few tens of entries.

2023-07-11net: fec: recycle pages for transmitted XDP framesWei Fang
Once the XDP frames have been successfully transmitted through the ndo_xdp_xmit() interface, it's the driver responsibility to free the frames so that the page_pool can recycle the pages and reuse them. However, this action is not implemented in the fec driver. This leads to a user-visible problem that the console will print the following warning log. [ 157.568851] page_pool_release_retry() stalled pool shutdown 1389 inflight 60 sec [ 217.983446] page_pool_release_retry() stalled pool shutdown 1389 inflight 120 sec [ 278.399006] page_pool_release_retry() stalled pool shutdown 1389 inflight 181 sec [ 338.812885] page_pool_release_retry() stalled pool shutdown 1389 inflight 241 sec [ 399.226946] page_pool_release_retry() stalled pool shutdown 1389 inflight 302 sec Therefore, to solve this issue, we free XDP frames via xdp_return_frame() while cleaning the tx BD ring.

2023-07-11net: fec: dynamically set the NETDEV_XDP_ACT_NDO_XMIT feature of XDPWei Fang
When a XDP program is installed or uninstalled, fec_restart() will be invoked to reset MAC and buffer descriptor rings. It's reasonable not to transmit any packet during the process of reset. However, the NETDEV_XDP_ACT_NDO_XMIT bit of xdp_features is enabled by default, that is to say, it's possible that the fec_enet_xdp_xmit() will be invoked even if the process of reset is not finished. In this case, the redirected XDP frames might be dropped and available transmit BDs may be incorrectly deemed insufficient. So this patch disable the NETDEV_XDP_ACT_NDO_XMIT feature by default and dynamically configure this feature when the bpf program is installed or uninstalled.

2023-07-10igc: Fix inserting of empty frame for launchtimeFlorian Kauer
The insertion of an empty frame was introduced with commit db0b124f02ba ("igc: Enhance Qbv scheduling by using first flag bit") in order to ensure that the current cycle has at least one packet if there is some packet to be scheduled for the next cycle. However, the current implementation does not properly check if a packet is already scheduled for the current cycle. Currently, an empty packet is always inserted if and only if txtime >= end_of_cycle && txtime > last_tx_cycle but since last_tx_cycle is always either the end of the current cycle (end_of_cycle) or the end of a previous cycle, the second part (txtime > last_tx_cycle) is always true unless txtime == last_tx_cycle. What actually needs to be checked here is if the last_tx_cycle was already written within the current cycle, so an empty frame should only be inserted if and only if txtime >= end_of_cycle && end_of_cycle > last_tx_cycle. This patch does not only avoid an unnecessary insertion, but it can actually be harmful to insert an empty packet if packets are already scheduled in the current cycle, because it can lead to a situation where the empty packet is actually processed as the first packet in the upcoming cycle shifting the packet with the first_flag even one cycle into the future, finally leading to a TX hang. The TX hang can be reproduced on a i225 with: sudo tc qdisc replace dev enp1s0 parent root handle 100 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ base-time 0 \ sched-entry S 01 300000 \ flags 0x1 \ txtime-delay 500000 \ clockid CLOCK_TAI sudo tc qdisc replace dev enp1s0 parent 100:1 etf \ clockid CLOCK_TAI \ delta 500000 \ offload \ skip_sock_check and traffic generator sudo trafgen -i traffic.cfg -o enp1s0 --cpp -n0 -q -t1400ns with traffic.cfg #define ETH_P_IP 0x0800 { /* Ethernet Header */ 0x30, 0x1f, 0x9a, 0xd0, 0xf0, 0x0e, # MAC Dest - adapt as needed 0x24, 0x5e, 0xbe, 0x57, 0x2e, 0x36, # MAC Src - adapt as needed const16(ETH_P_IP), /* IPv4 Header */ 0b01000101, 0, # IPv4 version, IHL, TOS const16(1028), # IPv4 total length (UDP length + 20 bytes (IP header)) const16(2), # IPv4 ident 0b01000000, 0, # IPv4 flags, fragmentation off 64, # IPv4 TTL 17, # Protocol UDP csumip(14, 33), # IPv4 checksum /* UDP Header */ 10, 0, 48, 1, # IP Src - adapt as needed 10, 0, 48, 10, # IP Dest - adapt as needed const16(5555), # UDP Src Port const16(6666), # UDP Dest Port const16(1008), # UDP length (UDP header 8 bytes + payload length) csumudp(14, 34), # UDP checksum /* Payload */ fill('W', 1000), } and the observed message with that is for example igc 0000:01:00.0 enp1s0: Detected Tx Unit Hang Tx Queue <0> TDH <32> TDT <3c> next_to_use <3c> next_to_clean <32> buffer_info[next_to_clean] time_stamp <ffff26a8> next_to_watch <00000000632a1828> jiffies <ffff27f8> desc.status <1048000> Fixes: db0b124f02ba ("igc: Enhance Qbv scheduling by using first flag bit") Signed-off-by: Florian Kauer <florian.kauer@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2023-07-10igc: No strict mode in pure launchtime/CBS offloadFlorian Kauer
The flags IGC_TXQCTL_STRICT_CYCLE and IGC_TXQCTL_STRICT_END prevent the packet transmission over slot and cycle boundaries. This is important for taprio offload where the slots and cycles correspond to the slots and cycles configured for the network. However, the Qbv offload feature of the i225 is also used for enabling TX launchtime / ETF offload. In that case, however, the cycle has no meaning for the network and is only used internally to adapt the base time register after a second has passed. Enabling strict mode in this case would unnecessarily prevent the transmission of certain packets (i.e. at the boundary of a second) and thus interferes with the ETF qdisc that promises transmission at a certain point in time. Similar to ETF, this also applies to CBS offload that also should not be influenced by strict mode unless taprio offload would be enabled at the same time. This fully reverts commit d8f45be01dd9 ("igc: Use strict cycles for Qbv scheduling") but its commit message only describes what was already implemented before that commit. The difference to a plain revert of that commit is that it now copes with the base_time = 0 case that was fixed with commit e17090eb2494 ("igc: allow BaseTime 0 enrollment for Qbv") In particular, enabling strict mode leads to TX hang situations under high traffic if taprio is applied WITHOUT taprio offload but WITH ETF offload, e.g. as in sudo tc qdisc replace dev enp1s0 parent root handle 100 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ base-time 0 \ sched-entry S 01 300000 \ flags 0x1 \ txtime-delay 500000 \ clockid CLOCK_TAI sudo tc qdisc replace dev enp1s0 parent 100:1 etf \ clockid CLOCK_TAI \ delta 500000 \ offload \ skip_sock_check and traffic generator sudo trafgen -i traffic.cfg -o enp1s0 --cpp -n0 -q -t1400ns with traffic.cfg #define ETH_P_IP 0x0800 { /* Ethernet Header */ 0x30, 0x1f, 0x9a, 0xd0, 0xf0, 0x0e, # MAC Dest - adapt as needed 0x24, 0x5e, 0xbe, 0x57, 0x2e, 0x36, # MAC Src - adapt as needed const16(ETH_P_IP), /* IPv4 Header */ 0b01000101, 0, # IPv4 version, IHL, TOS const16(1028), # IPv4 total length (UDP length + 20 bytes (IP header)) const16(2), # IPv4 ident 0b01000000, 0, # IPv4 flags, fragmentation off 64, # IPv4 TTL 17, # Protocol UDP csumip(14, 33), # IPv4 checksum /* UDP Header */ 10, 0, 48, 1, # IP Src - adapt as needed 10, 0, 48, 10, # IP Dest - adapt as needed const16(5555), # UDP Src Port const16(6666), # UDP Dest Port const16(1008), # UDP length (UDP header 8 bytes + payload length) csumudp(14, 34), # UDP checksum /* Payload */ fill('W', 1000), } and the observed message with that is for example igc 0000:01:00.0 enp1s0: Detected Tx Unit Hang Tx Queue <0> TDH <d0> TDT <f0> next_to_use <f0> next_to_clean <d0> buffer_info[next_to_clean] time_stamp <ffff661f> next_to_watch <00000000245a4efb> jiffies <ffff6e48> desc.status <1048000> Fixes: d8f45be01dd9 ("igc: Use strict cycles for Qbv scheduling") Signed-off-by: Florian Kauer <florian.kauer@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2023-07-10igc: Handle already enabled taprio offload for basetime 0Florian Kauer
Since commit e17090eb2494 ("igc: allow BaseTime 0 enrollment for Qbv") it is possible to enable taprio offload with a basetime of 0. However, the check if taprio offload is already enabled (and thus -EALREADY should be returned for igc_save_qbv_schedule) still relied on adapter->base_time > 0. This can be reproduced as follows: # TAPRIO offload (flags == 0x2) and base-time = 0 sudo tc qdisc replace dev enp1s0 parent root handle 100 stab overhead 24 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ base-time 0 \ sched-entry S 01 300000 \ flags 0x2 # The second call should fail with "Error: Device failed to setup taprio offload." # But that only happens if base-time was != 0 sudo tc qdisc replace dev enp1s0 parent root handle 100 stab overhead 24 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ base-time 0 \ sched-entry S 01 300000 \ flags 0x2 Fixes: e17090eb2494 ("igc: allow BaseTime 0 enrollment for Qbv") Signed-off-by: Florian Kauer <florian.kauer@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2023-07-10igc: Do not enable taprio offload for invalid argumentsFlorian Kauer
Only set adapter->taprio_offload_enable after validating the arguments. Otherwise, it stays set even if the offload was not enabled. Since the subsequent code does not get executed in case of invalid arguments, it will not be read at first. However, by activating and then deactivating another offload (e.g. ETF/TX launchtime offload), taprio_offload_enable is read and erroneously keeps the offload feature of the NIC enabled. This can be reproduced as follows: # TAPRIO offload (flags == 0x2) and negative base-time leading to expected -ERANGE sudo tc qdisc replace dev enp1s0 parent root handle 100 stab overhead 24 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ base-time -1000 \ sched-entry S 01 300000 \ flags 0x2 # IGC_TQAVCTRL is 0x0 as expected (iomem=relaxed for reading register) sudo pcimem /sys/bus/pci/devices/0000:01:00.0/resource0 0x3570 w*1 # Activate ETF offload sudo tc qdisc replace dev enp1s0 parent root handle 6666 mqprio \ num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \ queues 1@0 1@1 2@2 \ hw 0 sudo tc qdisc add dev enp1s0 parent 6666:1 etf \ clockid CLOCK_TAI \ delta 500000 \ offload # IGC_TQAVCTRL is 0x9 as expected sudo pcimem /sys/bus/pci/devices/0000:01:00.0/resource0 0x3570 w*1 # Deactivate ETF offload again sudo tc qdisc delete dev enp1s0 parent 6666:1 # IGC_TQAVCTRL should now be 0x0 again, but is observed as 0x9 sudo pcimem /sys/bus/pci/devices/0000:01:00.0/resource0 0x3570 w*1 Fixes: e17090eb2494 ("igc: allow BaseTime 0 enrollment for Qbv") Signed-off-by: Florian Kauer <florian.kauer@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2023-07-10igc: Rename qbv_enable to taprio_offload_enableFlorian Kauer
In the current implementation the flags adapter->qbv_enable and IGC_FLAG_TSN_QBV_ENABLED have a similar name, but do not have the same meaning. The first one is used only to indicate taprio offload (i.e. when igc_save_qbv_schedule was called), while the second one corresponds to the Qbv mode of the hardware. However, the second one is also used to support the TX launchtime feature, i.e. ETF qdisc offload. This leads to situations where adapter->qbv_enable is false, but the flag IGC_FLAG_TSN_QBV_ENABLED is set. This is prone to confusion. The rename should reduce this confusion. Since it is a pure rename, it has no impact on functionality.

The while-loop may break on one of the two conditions, either ID string is empty or GUID matches. The second one, may never be reached if the parsed string is not correct GUID. In such a case the loop will never advance to check the next ID. Break possible infinite loop by factoring out guid_parse_and_compare() helper which may be moved to the generic header for everyone later on and preventing from similar mistake in the future. Interestingly that firstly it appeared when WMI was turned into a bus driver, but later when duplicated GUIDs were checked, the while-loop has been replaced by for-loop and hence no mistake made again.

Rework the code in a way that helps readability and avoids the warning.

2023-07-08ntb: hw: amd: Fix debugfs_create_dir error checkingAnup Sharma
The debugfs_create_dir function returns ERR_PTR in case of error, and the only correct way to check if an error occurred is 'IS_ERR' inline function. This patch will replace the null-comparison with IS_ERR.
