      arm64: defconfig: Expand default enabled features · 55834a77
      Mark Rutland 提交于
      FPGA implementations of the Cortex-A57 and Cortex-A53 are now available
      in the form of the SMM-A57 and SMM-A53 Soft Macrocell Models (SMMs) for
      Versatile Express. As these attach to a Motherboard Express V2M-P1 it
      would be useful to have support for some V2M-P1 peripherals enabled by
      default.
      
      Additionally a couple of of features have been introduced since the last
      defconfig update (CMA, jump labels) that would be good to have enabled
      by default to ensure they are build and boot tested.
      
      This patch updates the arm64 defconfig to enable support for these
      devices and features. The arm64 Kconfig is modified to select
      HAVE_PATA_PLATFORM, which is required to enable support for the
      CompactFlash controller on the V2M-P1.
      
      A few options which don't need to appear in defconfig are trimmed:
      
      * BLK_DEV - selected by default
      * EXPERIMENTAL - otherwise gone from the kernel
      * MII - selected by drivers which require it
      * USB_SUPPORT - selected by default

      arch_timer: Move to generic sched_clock framework · 65cd4f6c
      Stephen Boyd 提交于
      Register with the generic sched_clock framework now that it
      supports 64 bits. This fixes two problems with the current
      sched_clock support for machines using the architected timers.
      First off, we don't subtract the start value from subsequent
      sched_clock calls so we can potentially start off with
      sched_clock returning gigantic numbers. Second, there is no
      support for suspend/resume handling so problems such as discussed
      in 6a4dae5e (ARM: 7565/1: sched: stop sched_clock() during
      suspend, 2012-10-23) can happen without this patch. Finally, it
      allows us to move the sched_clock setup into drivers clocksource
      out of the arch ports.

      xen/arm,arm64: enable SWIOTLB_XEN · 83862ccf
      Stefano Stabellini 提交于
      Xen on arm and arm64 needs SWIOTLB_XEN: when running on Xen we need to
      program the hardware with mfns rather than pfns for dma addresses.
      Remove SWIOTLB_XEN dependency on X86 and PCI and make XEN select
      SWIOTLB_XEN on arm and arm64.
      
      At the moment always rely on swiotlb-xen, but when Xen starts supporting
      hardware IOMMUs we'll be able to avoid it conditionally on the presence
      of an IOMMU on the platform.
      
      Implement xen_create_contiguous_region on arm and arm64: for the moment
      we assume that dom0 has been mapped 1:1 (physical addresses == machine
      addresses) therefore we don't need to call XENMEM_exchange. Simply
      return the physical address as dma address.
      
      Initialize the xen-swiotlb from xen_early_init (before the native
      dma_ops are initialized), set xen_dma_ops to &xen_swiotlb_dma_ops.

      Changes in v8:
      - assume dom0 is mapped 1:1, no need to call XENMEM_exchange.
      
      Changes in v7:
      - call __set_phys_to_machine_multi from xen_create_contiguous_region and
      xen_destroy_contiguous_region to update the P2M;
      - don't call XENMEM_unpin, it has been removed;
      - call XENMEM_exchange instead of XENMEM_exchange_and_pin;
      - set nr_exchanged to 0 before calling the hypercall.
      
      Changes in v6:
      - introduce and export xen_dma_ops;
      - call xen_mm_init from as arch_initcall.
      
      Changes in v4:
      - remove redefinition of DMA_ERROR_CODE;
      - update the code to use XENMEM_exchange_and_pin and XENMEM_unpin;
      - add a note about hardware IOMMU in the commit message.
      
      Changes in v3:
      - code style changes;
      - warn on XENMEM_put_dma_buf failures.
