      xen/gndev: Xen backend support for paged out grant targets V4. · c571898f
      Andres Lagar-Cavilla authored
      Since Xen-4.2, hvm domains may have portions of their memory paged out. When a
      foreign domain (such as dom0) attempts to map these frames, the map will
      initially fail. The hypervisor returns a suitable errno, and kicks an
      asynchronous page-in operation carried out by a helper. The foreign domain is
      expected to retry the mapping operation until it eventually succeeds. The
      foreign domain is not put to sleep because itself could be the one running the
      pager assist (typical scenario for dom0).
      
      This patch adds support for this mechanism for backend drivers using grant
      mapping and copying operations. Specifically, this covers the blkback and
      gntdev drivers (which map foreign grants), and the netback driver (which copies
      foreign grants).
      
      * Add a retry method for grants that fail with GNTST_eagain (i.e. because the
        target foreign frame is paged out).
      * Insert hooks with appropriate wrappers in the aforementioned drivers.
      
      The retry loop is only invoked if the grant operation status is GNTST_eagain.
      It guarantees to leave a new status code different from GNTST_eagain. Any other
      status code results in identical code execution as before.
      
      The retry loop performs 256 attempts with increasing time intervals through a
      32 second period. It uses msleep to yield while waiting for the next retry.
      
      V2 after feedback from David Vrabel:
      * Explicit MAX_DELAY instead of wrap-around delay into zero
      * Abstract GNTST_eagain check into core grant table code for netback module.
      
      V3 after feedback from Ian Campbell:
      * Add placeholder in array of grant table error descriptions for unrelated
        error code we jump over.
      * Eliminate single map and retry macro in favor of a generic batch flavor.
      * Some renaming.
      * Bury most implementation in grant_table.c, cleaner interface.
      
      V4 rebased on top of sync of Xen grant table interface headers.

      xen-pciback: support wild cards in slot specifications · c3cb4709
      Jan Beulich authored
      Particularly for hiding sets of SR-IOV devices, specifying them all
      individually is rather cumbersome. Therefore, allow function and slot
      numbers to be replaced by a wildcard character ('*').
      
      Unfortunately this gets complicated by the in-kernel sscanf()
      implementation not being really standard conformant - matching of
      plain text tails cannot be checked by the caller (a patch to overcome
      this will be sent shortly, and a follow-up patch for simplifying the
      code is planned to be sent when that fixed went upstream).

       "Another set of fixes for ARM dma-mapping subsystem.
      
        Commit e9da6e99 replaced custom consistent buffer remapping code
        with generic vmalloc areas.  It however introduced some regressions
        caused by limited support for allocations in atomic context.  This
        series contains fixes for those regressions.
      
        For some subplatforms the default, pre-allocated pool for atomic
        allocations turned out to be too small, so a function for setting its
        size has been added.
      
        Another set of patches adds support for atomic allocations to
        IOMMU-aware DMA-mapping implementation.
      
        The last part of this pull request contains two fixes for Contiguous
        Memory Allocator, which relax too strict requirements."

      Copy back of per-slot error codes is only necessary for V2. V1 does not provide

      xen/pciback: Fix proper FLR steps. · 80ba77df
      Konrad Rzeszutek Wilk authored
      When we do FLR and save PCI config we did it in the wrong order.
      The end result was that if a PCI device was unbind from
      its driver, then binded to xen-pciback, and then back to its
      driver we would get:
      
      > lspci -s 04:00.0

      e1000e: probe of 0000:04:00.0 failed with error -2
      
      This fixes it by first saving the PCI configuration space, then
      doing the FLR.
