2020-10-13vfio/fsl-mc: Fixed vfio-fsl-mc driver compilation on 32 bitDiana Craciun
The FSL_MC_BUS on which the VFIO-FSL-MC driver is dependent on can be compiled on other architectures as well (not only ARM64) including 32 bit architectures. Include linux/io-64-nonatomic-hi-lo.h to make writeq/readq used in the driver available on 32bit platforms.

2020-10-13Merge tag 'gpio-v5.10-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This time very little driver changes but lots of core changes. We have some interesting cooperative work for ARM and Intel alike, making the GPIO subsystem more and more suitable for industrial systems and the like, in addition to the in-kernel users. We touch driver core (device properties) and lib/* by adding one simple string array free function, these are authored by Andy Shevchenko who is a well known and recognized core helpers maintainers so this should be fine. We also see some Android GKI-related modularization in the MXC drivers. Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2. So we put in a new one and deprecate and obsolete the old one. - All example tools in tools/gpio/* are migrated to the new API to set a good example. The libgpiod userspace library has been augmented to use this new API pretty much from day 1. - Some misc API hardening by using strn* function calls has been added as well. - Use the simpler IDA interface for GPIO chip instance enumeration. - Add device core function for counting string arrays in device properties. - Provide a generic library function kfree_strarray() that can be used throughout the kernel. Driver enhancements: - The DesignWare dwapb-gpio driver has been enhanced and now uses the IRQ handling in the gpiolib core. - The mockup and aggregator drivers have seen some substantial code clean-up and now use more of the core kernel inftrastructure. - Misc cleanups using dev_err_probe(). - The MXC drivers (Freescale/NXP) can now be built modularized, which makes modularized GKI Android kernels happy" * tag 'gpio-v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (73 commits) gpiolib: Update header block in gpiolib-cdev.h gpiolib: cdev: switch from kstrdup() to kstrndup() docs: gpio: add a new document to its index.rst gpio: pca953x: Add support for the NXP PCAL9554B/C tools: gpio: add debounce support to gpio-event-mon tools: gpio: add multi-line monitoring to gpio-event-mon tools: gpio: port gpio-event-mon to v2 uAPI tools: gpio: port gpio-hammer to v2 uAPI tools: gpio: rename nlines to num_lines tools: gpio: port gpio-watch to v2 uAPI tools: gpio: port lsgpio to v2 uAPI gpio: uapi: document uAPI v1 as deprecated gpiolib: cdev: support setting debounce gpiolib: cdev: support GPIO_V2_LINE_SET_VALUES_IOCTL gpiolib: cdev: support GPIO_V2_LINE_SET_CONFIG_IOCTL gpiolib: cdev: support edge detection for uAPI v2 gpiolib: cdev: support GPIO_V2_GET_LINEINFO_IOCTL and GPIO_V2_GET_LINEINFO_WATCH_IOCTL gpiolib: cdev: support GPIO_V2_GET_LINE_IOCTL and GPIO_V2_LINE_GET_VALUES_IOCTL gpiolib: add build option for CDEV v1 ABI gpiolib: make cdev a build option ...

2020-10-13PCI: dwc: Fix MSI page leakage in suspend/resumeJisheng Zhang
Currently, dw_pcie_msi_init() allocates and maps page for msi, then program the PCIE_MSI_ADDR_LO and PCIE_MSI_ADDR_HI. The Root Complex may lose power during suspend-to-RAM, so when we resume, we want to redo the latter but not the former. If designware based driver (for example, pcie-tegra194.c) calls dw_pcie_msi_init() in resume path, the msi page will be leaked. As pointed out by Rob and Ard, there's no need to allocate a page for the MSI address, we could use an address in the driver data. To avoid map the MSI msg again during resume, we move the map MSI msg from dw_pcie_msi_init() to dw_pcie_host_init().

The MHU drives the signal using a 32-bit register, with all 32 bits logically ORed together. The MHU provides a set of registers to enable software to set, clear, and check the status of each of the bits of this register independently. The use of 32 bits for each interrupt line enables software to provide more information about the source of the interrupt. For example, each bit of the register can be associated with a type of event that can contribute to raising the interrupt. This patch adds a separate the MHU controller driver for doorbel mode of operation using the extended DT binding to add support the same.

2020-10-12net/mlx5e: IPsec: Add Connect-X IPsec Tx data path offloadRaed Salem
In the TX data path, spot packets with xfrm stack IPsec offload indication. Fill Software-Parser segment in TX descriptor so that the hardware may parse the ESP protocol, and perform TX checksum offload on the inner payload. Support GSO, by providing the trailer data and ICV placeholder so HW can fill it post encryption operation. Padding alignment cannot be performed in HW (ConnectX-6Dx) due to a bug. Software can overcome this limitation by adding NETIF_F_HW_ESP to the gso_partial_features field in netdev so the packets being aligned by the stack. l4_inner_checksum cannot be offloaded by HW for IPsec tunnel type packet. Note that for GSO SKBs, the stack does not include an ESP trailer, unlike the non-GSO case. Below is the iperf3 performance report on two server of 24 cores Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz with ConnectX6-DX. All the bandwidth test uses iperf3 TCP traffic with packet size 128KB. Each tunnel uses one iperf3 stream with one thread (option -P1).

The phy_reset_after_clk_enable() is always called with ndev->phydev, however that pointer may be NULL even though the PHY device instance already exists and is sufficient to perform the PHY reset. This condition happens in fec_open(), where the clock must be enabled first, then the PHY must be reset, and then the PHY IDs can be read out of the PHY. If the PHY still is not bound to the MAC, but there is OF PHY node and a matching PHY device instance already, use the OF PHY node to obtain the PHY device instance, and then use that PHY device instance when triggering the PHY reset.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 irq updates from Thomas Gleixner: "Surgery of the MSI interrupt handling to prepare the support of upcoming devices which require non-PCI based MSI handling: - Cleanup historical leftovers all over the place - Rework the code to utilize more core functionality - Wrap XEN PCI/MSI interrupts into an irqdomain to make irqdomain assignment to PCI devices possible. - Assign irqdomains to PCI devices at initialization time which allows to utilize the full functionality of hierarchical irqdomains. - Remove arch_.*_msi_irq() functions from X86 and utilize the irqdomain which is assigned to the device for interrupt management. - Make the arch_.*_msi_irq() support conditional on a config switch and let the last few users select it" * tag 'x86-irq-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) PCI: MSI: Fix Kconfig dependencies for PCI_MSI_ARCH_FALLBACKS x86/apic/msi: Unbreak DMAR and HPET MSI iommu/amd: Remove domain search for PCI/MSI iommu/vt-d: Remove domain search for PCI/MSI[X] x86/irq: Make most MSI ops XEN private x86/irq: Cleanup the arch_*_msi_irqs() leftovers PCI/MSI: Make arch_.*_msi_irq[s] fallbacks selectable x86/pci: Set default irq domain in pcibios_add_device() iommm/amd: Store irq domain in struct device iommm/vt-d: Store irq domain in struct device x86/xen: Wrap XEN MSI management into irqdomain irqdomain/msi: Allow to override msi_domain_alloc/free_irqs() x86/xen: Consolidate XEN-MSI init x86/xen: Rework MSI teardown x86/xen: Make xen_msi_init() static and rename it to xen_hvm_msi_init() PCI/MSI: Provide pci_dev_has_special_msi_domain() helper PCI_vmd_Mark_VMD_irqdomain_with_DOMAIN_BUS_VMD_MSI irqdomain/msi: Provide DOMAIN_BUS_VMD_MSI x86/irq: Initialize PCI/MSI domain at PCI init time x86/pci: Reducde #ifdeffery in PCI init code ...
