2016-02-05drm/dp/mst: move GUID storage from mgr, port to only mst branchHersen Wu2-51/+38
Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

2016-02-05drm/dp/mst: change MST detection schemeMykola Lysenko1-18/+19
1. Get edid for all connected MST displays, not only on logical ports, in the same thread as MST topology detection is done: There are displays that have branches inside w/o logical ports. So in case another SST display connected downstream system can end-up in situation when 3 DOWN requests sent: two for ‘remote i2c read’ and one for ‘enum path resources’, making slots full. 2. Call notification callback in one place in the end of topology discovery/update: This is done to reduce number of events sent to userspace in case complex topology discovery is going, adding multiple number of connectors; 3. Remove notification callback call from short pulse interrupt processing function: This is done in order not to block interrupt processing function, in case any MST request will be made from it. Notification will be send from topology discovery/update work item.

2016-02-05drm/dp/mst: Calculate MST PBN with 31.32 fixed pointHarry Wentland1-28/+39
Our PBN value overflows the 20 bits integer part of the 20.12 fixed point. We need to use 31.32 fixed point to avoid this. This happens with display clocks larger than 293122 (at 24 bpp), which we see with the Sharp (and similar) 4k tiled displays.

2016-02-05drm: Add drm_fixp_from_fraction and drm_fixp2int_ceilHarry Wentland1-2/+51
drm_fixp_from_fraction allows us to create a fixed point directly from a fraction, rather than creating fixed point values and dividing later. This avoids overflow of our 64 bit value for large numbers. drm_fixp2int_ceil allows us to return the ceiling of our fixed point value.

2016-02-04xhci: harden xhci_find_next_ext_cap against device removalJoe Lawrence1-0/+4
xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use the PCI master abort bit pattern (~0) to calculate a new PCI address offset to read/write. The has lead to reproducable crashes when testing surprise removal during device initialization on a Stratus platform, at least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability list parsing functions"). The crash is repeatable on a Stratus platform when injecting hardware faults to induce xHCI host controller hotplug during driver initialization. If a PCI read in xhci_find_next_ext_cap returns the master abort pattern, quirk_usb_handoff_xhci may start using a bogus ext_cap_offset to start searching more bogus PCI addresses.

2016-02-04ARM: nomadik: fix up SD/MMC DT settingsLinus Walleij1-17/+20
The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

2016-02-04ALSA: timer: Fix leftover link at closingTakashi Iwai1-2/+2
In ALSA timer core, the active timer instance is managed in active_list linked list. Each element is added / removed dynamically at timer start, stop and in timer interrupt. The problem is that snd_timer_interrupt() has a thinko and leaves the element in active_list when it's the last opened element. This eventually leads to list corruption or use-after-free error. This hasn't been revealed because we used to delete the list forcibly in snd_timer_stop() in the past. However, the recent fix avoids the double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link corruption due to double start or stop]), and this leak hits reality. This patch fixes the link management in snd_timer_interrupt(). Now it simply unlinks no matter which stream is.

2016-02-04drm/i915/fbc: unexport the HW level activation functionsPaulo Zanoni2-29/+40
The recent introduction of a new caller of dev_priv->fbc.deactivate() is a good example of why we need unexport those functions. Anything outside intel_fbc.c should only call the functions exported by intel_fbc.c, so in order to enforce that, kill the function pointers stored inside dev_priv->fbc and replace them with functions that can't be called from outside intel_fbc.c. This should make it much harder for new code to call these functions from outside intel_fbc.c.

2016-02-04drm/i915: don't deactivate FBC at skylake_disable_primary_planePaulo Zanoni1-3/+0
FBC is already deactivated at this point. Besides, nothing should be calling these lower-level function pointers. A few months ago, the only caller of dev_priv->fbc.deactivate was intel_pipe_set_base_atomic(), which was the kgdboc function. But the following commit added it to the SKL function: commit a8d201af68506b375b701d0d8dbe8487034256f2 Author: Maarten Lankhorst <[email protected]> Date: Thu Jan 7 11:54:11 2016 +0100 drm/i915: Use plane state for primary plane updates.

2016-02-04drm/i915: implement WaIncreaseDefaultTLBEntriesTim Gore2-0/+28
WaIncreaseDefaultTLBEntries increases the number of TLB entries available for GPGPU workloads and gives significant ( > 10% ) performance gain for some OCL benchmarks. Put this in a new function that can be a place for workarounds that are GT related but not required per ring. This function is called on driver load and also after a reset and on resume, so it is safe for workarounds that get clobbered in these situations. This function currently has just this one workaround. v2: This was originally split into 3 patches but following review feedback was squashed into 1. I have not incorporated some style comments from Chris Wilson as I felt that after defining and intialising a temporary variable and then adding an additional if block to only write the register if the temporary variable had been set, this didn't really give a net gain. v3: Resending in the hope that BAT will run v4: Change subject line to trigger BAT (please!)

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab1-1/+1
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: [email protected] # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil3-54/+46
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver.

2016-02-04[media] tda1004x: only update the frontend properties if lockedMauro Carvalho Chehab1-0/+9
The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning. This caused the driver to fail with libdvbv5, as such library calls GET_PROPERTY from time to time, in order to return the DVB stats.

2016-02-03usb: xhci-mtk: fix AHB bus hang up caused by roothubs pollingChunfeng Yun1-0/+23
when ip fails to enter sleep mode, register access protection will be disabled, at the same time if all clocks are disabled, access register will hang up AHB bus. the common case causes ip sleep failure is that after all ports enter U3 but before ip enters sleep mode, a port receives a resume signal('K'). this will happens when such as clicks mouse to try to do remote-wakeup to stop system enter suspend. so stop polling root hubs to avoid access xHCI register on bus suspend, and restart it when bus resumes.

XHCI_SSIC_PORT_UNUSED quirk was applied to the xHCI host controllers in some Intel SoC chips. With this quirk applied, SSIC port is set to "unused" prior to xhci_suspend(). This may cause problem if host fails to suspend. In this case, the port is set to unused without host further entering D3, and the port will not be usable anymore.
