      staging/lustre: remove IOC_LIBCFS_PING_TEST ioctl · d035e336
      James Simmons authored
      The ioctl IOC_LIBCFS_PING_TEST has not been used in ages.  The recent
      nidstring changes which moved all the nidstring operations from libcfs
      to the LNet layer but this ioctl code was still using an nidstring
      operation that was causing a circular dependency loop between libcfs and
      LNet.

      we already zero it on outermost set_nameidata(), so initialization in
      path_init() is pointless and wrong.  The same DoS exists on pre-4.2
      kernels, but there a slightly different fix will be needed.

      ovl: fix permission checking for setattr · acff81ec
      Miklos Szeredi authored
      [Al Viro] The bug is in being too enthusiastic about optimizing ->setattr()
      away - instead of "copy verbatim with metadata" + "chmod/chown/utimes"
      (with the former being always safe and the latter failing in case of
      insufficient permissions) it tries to combine these two.  Note that copyup
      itself will have to do ->setattr() anyway; _that_ is where the elevated
      capabilities are right.  Having these two ->setattr() (one to set verbatim
      copy of metadata, another to do what overlayfs ->setattr() had been asked
      to do in the first place) combined is where it breaks.

      drm/amdgpu: Fixup hw vblank counter/ts for new drm_update_vblank_count() (v3) · 8e36f9d3
      Alex Deucher authored
      commit 4dfd6486 "drm: Use vblank timestamps to guesstimate how many
      vblanks were missed" introduced in Linux 4.4-rc1 makes the drm core
      more fragile to drivers which don't update hw vblank counters and
      vblank timestamps in sync with firing of the vblank irq and
      essentially at leading edge of vblank.
      
      This exposed a problem with radeon-kms/amdgpu-kms which do not
      satisfy above requirements:
      
      The vblank irq fires a few scanlines before start of vblank, but
      programmed pageflips complete at start of vblank and
      vblank timestamps update at start of vblank, whereas the
      hw vblank counter increments only later, at start of vsync.
      
      This leads to problems like off by one errors for vblank counter
      updates, vblank counters apparently going backwards or vblank
      timestamps apparently having time going backwards. The net result
      is stuttering of graphics in games, or little hangs, as well as
      total failure of timing sensitive applications.
      
      See bug #93147 for an example of the regression on Linux 4.4-rc:
      
      https://bugs.freedesktop.org/show_bug.cgi?id=93147
      
      This patch tries to align all above events better from the
      viewpoint of the drm core / of external callers to fix the problem:
      
      1. The apparent start of vblank is shifted a few scanlines earlier,
      so the vblank irq now always happens after start of this extended
      vblank interval and thereby drm_update_vblank_count() always samples
      the updated vblank count and timestamp of the new vblank interval.
      
      To achieve this, the reporting of scanout positions by
      radeon_get_crtc_scanoutpos() now operates as if the vblank starts
      radeon_crtc->lb_vblank_lead_lines before the real start of the hw
      vblank interval. This means that the vblank timestamps which are based
      on these scanout positions will now update at this earlier start of
      vblank.
      
      2. The driver->get_vblank_counter() function will bump the returned
      vblank count as read from the hw by +1 if the query happens after
      the shifted earlier start of the vblank, but before the real hw increment
      at start of vsync, so the counter appears to increment at start of vblank
      in sync with the timestamp update.
      
      3. Calls from vblank irq-context and regular non-irq calls are now
      treated identical, always simulating the shifted vblank start, to
      avoid inconsistent results for queries happening from vblank irq vs.
      happening from drm_vblank_enable() or vblank_disable_fn().
      
      4. The radeon_flip_work_func will delay mmio programming a pageflip until
      the start of the real vblank iff it happens to execute inside the shifted
      earlier start of the vblank, so pageflips now also appear to execute at
      start of the shifted vblank, in sync with vblank counter and timestamp
      updates. This to avoid some races between updates of vblank count and
      timestamps that are used for swap scheduling and pageflip execution which
      could cause pageflips to execute before the scheduled target vblank.
      
      The lb_vblank_lead_lines "fudge" value is calculated as the size of
      the display controllers line buffer in scanlines for the given video
      mode: Vblank irq's are triggered by the line buffer logic when the line
      buffer refill for a video frame ends, ie. when the line buffer source read
      position enters the hw vblank. This means that a vblank irq could fire at
      most as many scanlines before the current reported scanout position of the
      crtc timing generator as the number of scanlines the line buffer can
      maximally hold for a given video mode.
      
      This patch has been successfully tested on a RV730 card with DCE-3 display
      engine and on a evergreen card with DCE-4 display engine, in single-display
      and dual-display configuration, with different video modes.
      
      A similar patch is needed for amdgpu-kms to fix the same problem.
      
      Limitations:
      
      - Maybe replace the udelay() in the flip_work_func() by a suitable
        usleep_range() for a bit better efficiency? Will try that.
      
      - Line buffer sizes in pixels are hard-coded on < DCE-4 to a value
        i just guessed to be high enough to work ok, lacking info on the true
        sizes atm.
      
      Probably fixes: fdo#93147

           usleep_range() until at least predicted true start of hw vblank,
           with some slack for scheduler happiness. Release the event lock
           during waits to not delay other outputs in doing their stuff, as
           the waiting can last up to 200 usecs in some cases.

      most as many scanlines before the current reported scanout position of the
      crtc timing generator as the number of scanlines the line buffer can
      maximally hold for a given video mode.
      
      This patch has been successfully tested on a RV730 card with DCE-3 display
      engine and on a evergreen card with DCE-4 display engine, in single-display
      and dual-display configuration, with different video modes.
      
      A similar patch is needed for amdgpu-kms to fix the same problem.
      
      Limitations:
      
      - Line buffer sizes in pixels are hard-coded on < DCE-4 to a value
        i just guessed to be high enough to work ok, lacking info on the true
        sizes atm.

      (v2) Refine radeon_flip_work_func() for better efficiency:
      
           In radeon_flip_work_func, replace the busy waiting udelay(5)
           with event lock held by a more performance and energy efficient
           usleep_range() until at least predicted true start of hw vblank,
           with some slack for scheduler happiness. Release the event lock
           during waits to not delay other outputs in doing their stuff, as
           the waiting can last up to 200 usecs in some cases.
      
           Retested on DCE-3 and DCE-4 to verify it still works nicely.

      drm/radeon: Retry DDC probing on DVI on failure if we got an HPD interrupt · cb5d4166
      Lyude authored
      HPD signals on DVI ports can be fired off before the pins required for
      DDC probing actually make contact, due to the pins for HPD making
      contact first. This results in a HPD signal being asserted but DDC
      probing failing, resulting in hotplugging occasionally failing.
      
      This is somewhat rare on most cards (depending on what angle you plug
      the DVI connector in), but on some cards it happens constantly. The
      Radeon R5 on the machine used for testing this patch for instance, runs
      into this issue just about every time I try to hotplug a DVI monitor and
      as a result hotplugging almost never works.
      
      Rescheduling the hotplug work for a second when we run into an HPD
      signal with a failing DDC probe usually gives enough time for the rest
      of the connector's pins to make contact, and fixes this issue.

       "This time we've got a larger number of updates, mainly from ASoC
        world.  The only significant LOCs found here are for Realtek codecs,
        where most of changes are quite systematic replacements.
      
        There are also a few fixes in ASoC core side: one is the PM call order
        fix to ensure the DPAM resume working properly.  Another is the proper
        cleanup call after freeing DAPM widgets, and the correction of the
        wrong callback set in topology API.
      
        The rest are a wide range of driver-specific small fixes, including
        HD-audio"
