      drm/i915: Wait for vblank before enabling the TV encoder · 7a98948f
      Ville Syrjälä 提交于
      The vblank waits in intel_tv_detect_type() are timing out for some
      reason. This is a regression caused removing seemingly useless vblank
      waits from the modeset seqeuence in:

          drm/i915: Kill vblank waits after pipe enable on gmch platforms
      
      So it turns out they weren't all entirely useless. Apparently the pipe
      has to go through one full frame before we enable the TV port. Add a
      vblank wait to intel_enable_tv() to make sure that happens.
      
      Another approach was attempted by placing the vblank wait just after
      enabling the port. The theory behind that attempt was that we need to
      let the port stay enabled for one full frame before disabling it again
      during load detection. But that didn't work, and we definitely must
      have the vblank wait before enabling the port.

      drm/i915: Evict CS TLBs between batches · c4d69da1
      Chris Wilson 提交于
      Running igt, I was encountering the invalid TLB bug on my 845g, despite
      that it was using the CS workaround. Examining the w/a buffer in the
      error state, showed that the copy from the user batch into the
      workaround itself was suffering from the invalid TLB bug (the first
      cacheline was broken with the first two words reversed). Time to try a
      fresh approach. This extends the workaround to write into each page of
      our scratch buffer in order to overflow the TLB and evict the invalid
      entries. This could be refined to only do so after we update the GTT,
      but for simplicity, we do it before each batch.
      
      I suspect this supersedes our current workaround, but for safety keep
      doing both.
      
      v2: The magic number shall be 2.
      
      This doesn't conclusively prove that it is the mythical TLB bug we've
      been trying to workaround for so long, that it requires touching a number
      of pages to prevent the corruption indicates to me that it is TLB
      related, but the corruption (the reversed cacheline) is more subtle than
      a TLB bug, where we would expect it to read the wrong page entirely.
      
      Oh well, it prevents a reliable hang for me and so probably for others
      as well.

      drm/i915: Fix irq enable tracking in driver load · 4868b45d
      Daniel Vetter 提交于
      A bunch of warnings fire on some ->irq_postinstall hooks since those
      can enable interrupts (e.g. rps interrupts). And then our ordering
      self-checks fire and complain.
      
      To fix that set the tracking boolen before enabling the irqs with
      drm_irq_install. Quoting the discussion with Jesse why that's safe:
      
      On Tue, Aug 26, 2014 at 11:18 PM, Jesse Barnes <jbarnes@virtuousgeek.org> wrote:

      Well we've done it in 4 commits or so, but currently we have:
      
      - Set irqs_disabled to true early in driver load to make sure checks
      that. That's done in irq_init, which is totally not the function that
      enables interrupts, only the function that initializes all the vtables
      and similar things. We actually have a fairly sane naming scheme
      nowadays (not fully consistent ofc): _init is sw setup,
      _enable/_hw_init is the actual hw setup. That is done in
      95f25bed
      
      - Set irqs_disabled to false right after the irqs are actually
      enabled. This is done in ed2e6df1
      
      So my change should only move the flag change over the ->preinstall
      and ->postinstall hooks. I've done a little audit and didn't spot
      anything amiss. Furthermore the runtime pm setup already clears
      irqs_disabled _before_ calling these two hooks.
      
      This regression has been introduced in

      drm/i915: Prevent recursive deadlock on releasing a busy userptr · ad46cb53
      Chris Wilson 提交于
      During release of the GEM object we hold the struct_mutex. As the
      object may be holding onto the last reference for the task->mm,
      calling mmput() may trigger exit_mmap() which close the vma
      which will call drm_gem_vm_close() and attempt to reacquire
      the struct_mutex. In order to avoid that recursion, we have
      to defer the mmput() until after we drop the struct_mutex,
      i.e. we need to schedule a worker to do the clean up. A further issue
      spotted by Tvrtko was caused when we took a GTT mmapping of a userptr
      buffer object. In that case, we would never call mmput as the object
      would be cyclically referenced by the GTT mmapping and not freed upon
      process exit - keeping the entire process mm alive after the process
      task was reaped. The fix employed is to replace the mm_users/mmput()
      reference handling to mm_count/mmdrop() for the shared i915_mm_struct.

      ====================
      pull request: wireless 2014-09-05
      
      Please pull this batch of fixes intended for the 3.17 stream...
      
      For the mac80211 bits, Johannes says:
      
      "Here are a few fixes for mac80211. One has been discussed for a while
      and adds a terminating NUL-byte to the alpha2 sent to userspace, which
      shouldn't be necessary but since many places treat it as a string we
      couldn't move to just sending two bytes.
      
      In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
      fix for the recently introduced RX aggregation offload, a revert for
      a broken patch (that luckily didn't really cause any harm) and a small
      fix for alignment in debugfs."
      
      For the iwlwifi bits, Emmanuel says:
      
      "I revert a patch that disabled CTS to self in dvm because users
      reported issues. The revert is CCed to stable since the offending
      patch was sent to stable too. I also bump the firmware API versions
      since a new firmware is coming up. On top of that, Marcel fixes a
      bug I introduced while fixing a bug in our Kconfig file."
      
      Please let me know if there are problems!

      ipv6: restore the behavior of ipv6_sock_ac_drop() · de185ab4
      WANG Cong 提交于
      It is possible that the interface is already gone after joining
      the list of anycast on this interface as we don't hold a refcount
      for the device, in this case we are safe to ignore the error.
      
      What's more important, for API compatibility we should not
      change this behavior for applications even if it were correct.

      Documentation: NFS/RDMA: Document separate Kconfig symbols · 731d5cca
      Paul Bolle 提交于
      The NFS/RDMA Kconfig symbol was split into separate options for client
      and server in commit 2e8c12e1 ("xprtrdma: add separate Kconfig
      options for NFSoRDMA client and server support").
      
      Update the documentation to reflect this split.
