2023-08-26genirq: Fix software resend lockup and nested resendJohan Hovold
The switch to using hlist for managing software resend of interrupts broke resend in at least two ways: First, unconditionally adding interrupt descriptors to the resend list can corrupt the list when the descriptor in question has already been added. This causes the resend tasklet to loop indefinitely with interrupts disabled as was recently reported with the Lenovo ThinkPad X13s after threaded NAPI was disabled in the ath11k WiFi driver. This bug is easily fixed by restoring the old semantics of irq_sw_resend() so that it can be called also for descriptors that have already been marked for resend. Second, the offending commit also broke software resend of nested interrupts by simply discarding the code that made sure that such interrupts are retriggered using the parent interrupt. Add back the corresponding code that adds the parent descriptor to the resend list.

2023-08-26PCI: epf-mhi: Use iATU for small transfersManivannan Sadhasivam
For transfers below 4K, let's use iATU since using eDMA for such small transfers is inefficient. This is mainly because setting up an eDMA transfer and waiting for completion adds some latency. This latency is negligible for large transfers but not for the smaller ones. With using iATU, there is an increase in ~50Mbps throughput on both MHI UL (Uplink) and DL (Downlink) channels.

Add support for Embedded DMA (eDMA) available in the DesignWare PCIe IP to transfer the MHI buffers between the host and the endpoint. The eDMA use helps achieve greater throughput as the transfers are offloaded from CPUs. For differentiating the iATU and eDMA APIs, the pci_epf_mhi_{read/write} APIs are renamed to pci_epf_mhi_iatu_{read/write} and separate eDMA specific APIs pci_epf_mhi_edma_{read/write} are introduced. Platforms that require eDMA support can pass the MHI_EPF_USE_DMA flag through pci_epf_mhi_ep_info.

Qualcomm PCIe Endpoint controllers have the in-built Embedded DMA (eDMA) peripheral for offloading the data transfer between the PCIe bus and memory. Let's add support for it by enabling the eDMA IRQ in the driver. The eDMA DMA Engine driver will handle the rest of the functionality. Since the eDMA on Qualcomm platforms only uses a single IRQ for all channels, use 1 for edma.nr_irqs.

2023-08-26LoongArch: Ensure FP/SIMD registers in the core dump file is up to dateHuacai Chen
This is a port of commit 379eb01c21795edb4c ("riscv: Ensure the value of FP registers in the core dump file is up to date"). The values of FP/SIMD registers in the core dump file come from the thread.fpu. However, kernel saves the FP/SIMD registers only before scheduling out the process. If no process switch happens during the exception handling, kernel will not have a chance to save the latest values of FP/SIMD registers. So it may cause their values in the core dump file incorrect. To solve this problem, force fpr_get()/simd_get() to save the FP/SIMD registers into the thread.fpu if the target task equals the current task.

Older PA-RISC machines have LEDs which show the disk- and LAN-activity. The computation is done in software and takes quite some time, e.g. on a J6500 this may take up to 60% time of one CPU if the machine is loaded via network traffic. Since most people don't care about the LEDs, start with LEDs disabled and just show a CPU heartbeat LED. The disk and LAN LEDs can be turned on manually via /proc/pdc/led.

2023-08-25Merge branch 'stmmac-cleanups'Jakub Kicinski
Russell King says: ==================== stmmac cleanups One of the comments I had on Feiyang Chen's series was concerning the initialisation of phylink... and so I've decided to do something about it, cleaning it up a bit. This series: 1) adds a new phylink function to limit the MAC capabilities according to a maximum speed. This allows us to greatly simplify stmmac's initialisation of phylink's mac capabilities. 2) everywhere that uses priv->plat->phylink_node first converts this to a fwnode before doing anything with it. This is silly. Let's instead store it as a fwnode to eliminate these conversions in multiple places. 3) clean up passing the fwnode to phylink - it might as well happen at the phylink_create() callsite, rather than being scattered throughout the entire function. 4) same for mdio_bus_data 5) use phylink_limit_mac_speed() to handle the priv->plat->max_speed restriction. 6) add a method to get the MAC-specific capabilities from the code dealing with the MACs, and arrange to call it at an appropriate time. 7) convert the gmac4 users to use the MAC specific method. 8) same for xgmac. 9) group all the simple phylink_config initialisations together. 10) convert half-duplex logic to being positive logic. While looking into all of this, this raised eyebrows: if (priv->plat->tx_queues_to_use > 1) priv->phylink_config.mac_capabilities &= ~(MAC_10HD | MAC_100HD | MAC_1000HD); priv->plat->tx_queues_to_use is initialised by platforms to either 1, 4 or 8, and can be controlled from userspace via the --set-channels ethtool op. The implementation of this op in this driver limits the number of channels to priv->dma_cap.number_tx_queues, which is derived from the DMA hwcap. So, the obvious questions are: 1) what guarantees that the static initialisation of tx_queues_to_use will always be less than or equal to number_tx_queues from the DMA hw cap? 2) tx_queues_to_use starts off as 1, but number_tx_queues is larger, we will leave the half-duplex capabilities in place, but userspace can increase tx_queues_to_use above 1. Does that mean half-duplex is then not supported? 3) Should we be basing the decision whether half-duplex is supported off the DMA capabilities? 4) What about priv->dma_cap.half_duplex? Doesn't that get a say in whether half-duplex is supported or not? Why isn't this used? Why is it only reported via debugfs? If it's not being used by the driver, what's the point of reporting it via debugfs? ==================== Link: https://lore.kernel.org/r/ZOddFH22PWmOmbT5@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-08-25veth: Avoid NAPI scheduling on failed SKB forwardingLiang Chen
When an skb fails to be forwarded to the peer(e.g., skb data buffer length exceeds MTU), it will not be added to the peer's receive queue. Therefore, we should schedule the peer's NAPI poll function only when skb forwarding is successful to avoid unnecessary overhead.

2023-08-25cteonxt2-pf: Fix backpressure config for multiple PFC priorities to work ↵Suman Ghosh
simultaneously MAC (CGX or RPM) asserts backpressure at TL3 or TL2 node of the egress hierarchical scheduler tree depending on link level config done. If there are multiple PFC priorities enabled at a time and for all such flows to backoff, each priority will have to assert backpressure at different TL3/TL2 scheduler nodes and these flows will need to submit egress pkts to these nodes. Current PFC configuration has an issue where in only one backpressure scheduler node is being allocated which is resulting in only one PFC priority to work. This patch fixes this issue.

2023-08-25LoadPin: Annotate struct dm_verity_loadpin_trusted_root_digest with __counted_byKees Cook
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct dm_verity_loadpin_trusted_root_digest. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

2023-08-25PCI/PM: Only read PCI_PM_CTRL register when availableFeiyang Chen
For a device with no Power Management Capability, pci_power_up() previously returned 0 (success) if the platform was able to put the device in D0, which led to pci_set_full_power_state() trying to read PCI_PM_CTRL, even though it doesn't exist. Since dev->pm_cap == 0 in this case, pci_set_full_power_state() actually read the wrong register, interpreted it as PCI_PM_CTRL, and corrupted dev->current_state. This led to messages like this in some cases: pci 0000:01:00.0: Refused to change power state from D3hot to D0 To prevent this, make pci_power_up() always return a negative failure code if the device lacks a Power Management Capability, even if non-PCI platform power management has been able to put the device in D0. The failure will prevent pci_set_full_power_state() from trying to access PCI_PM_CTRL.
