      drm/atomic: Clear crtc_state->active in drm_atomic_helper_set_config. · 9b5edbf7
      Maarten Lankhorst authored
      This fixes some regressions in i915 when converting to atomic.
      set_config failed with -EINVAL, and I received the following warning
      in dmesg:
      
      [drm:drm_atomic_crtc_check] [CRTC:20] active without enabled
      
      Solve this by clearing active when a crtc is disabled.
      
      Because crtc_state->enable implies that connectors are active the
      change from disabled->enabled can only happen for the crtc that's
      being set_config'd, and checking for !crtc_state->enable is sufficient
      here.

      Dave Airlie authored
      One more round of drm-misc, again mostly atomic. Big thing is the
      userspace blob code from Daniel Stone, with support for the mode_id blob
      now added to the atomic ioctl. Finally we can do atomic modesets!
      
      Note that the atomic ioctl is still behind the module knob since the
      weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
      which is a fairly crucial bit of the atomic api. But besides that I think
      it's all good to go. That's also why we didn't bother to hide the new blob
      ioctls behind the knob, that part won't need to change. And if weston
      patches get in shape in time we could throw the "atomic by default patch"
      on top for 4.2.

      drm-amdkfd-next-2015-06-03:
      
      - Add the H/W debugger support module, including new IOCTLs to:
        - register/unregister a process as a debugged process
        - Set address watch-point in the debugged process's GPU kernel
        - Do a wave control operation in the debugged process's waves
        See the commit messages for more details on the available operations.
      
        The debugged process can only perform debug operation on itself. It is
        blocked by the amdkfd+H/W from performing operations on other processes's
        waves or GPU kernels. The blocking is done by setting the VMID and PASID of
        the debugged process in the packets that are sent to the CP with the debug
        instructions.
      
      - Add support for static user-mode queues. These queues are regular queues,
        but because they belong to the debugged process, we need to make sure the CP
        doesn't preempt them during a debug operation. Therefore, we mark them as
        static for the CP ignore them during preemption.
      
      - Support killing all the waves when a process is terminated. This is needed
        in case a process is terminated but we can't UNMAP its queues (can occur due
        to several reasons). In that case, the CP could be stuck unless we kill all
        its waves. This function is *very* important as it provides the kernel a high
        level of control over the GPU. The reason we didn't upstream this function
        so far, is because it is implemented using the H/W debugger module functions,
        so we had to wait until we can upstream the H/W debugger module.
      
      - Replace declaration of bitmap from unsigned long to standard DECLARE_BITMAP

      Add virtio gpu driver. · dc5698e8
      Dave Airlie authored
      This patch adds a kms driver for the virtio gpu.  The xorg modesetting
      driver can handle the device just fine, the framebuffer for fbcon is
      there too.
      
      Qemu patches for the host side are under review currently.
      
      The pci version of the device comes in two variants: with and without
      vga compatibility.  The former has a extra memory bar for the vga
      framebuffer, the later is a pure virtio device.  The only concern for
      this driver is that in the virtio-vga case we have to kick out the
      firmware framebuffer.
      
      Initial revision has only 2d support, 3d (virgl) support requires
      some more work on the qemu side and will be added later.

      This commit makes sure that on process termination, after
      we're destroying all the active queues, we're killing all the
      existing wave front of the current process.
      
      By doing this we're making sure that if any of the CUs were blocked
      by infinite loop we're enforcing it to end the shader explicitly.

      drm/amdkfd: Add static user-mode queues support · 992839ad

      This patch adds support for static user-mode queues in QCM.
      Queues which are designated as static can NOT be preempted by
      the CP microcode when it is executing its scheduling algorithm.
      
      This is needed for supporting the debugger feature, because we
      can't allow the CP to preempt queues which are currently being debugged.
      
      The number of queues that can be designated as static is limited by the

      drm/amdkfd: add H/W debugger IOCTL set definitions · aef11009
      Yair Shachar authored
      This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W
      debugger functionality to the userspace.
      
      The IOCTLs are:
      
      - AMDKFD_IOC_DBG_REGISTER:
      
      The purpose of this IOCTL is to notify amdkfd that a process wants to use
      GPU debugging facilities on itself only.
      It is expected that this IOCTL would be called before any other H/W
      debugger requests are sent to amdkfd and for each GPU where the H/W
      debugging needs to be enabled. The use of this IOCTL ensures that only
      one instance of a debugger is active in the system.
      
      - AMDKFD_IOC_DBG_UNREGISTER:
      
      This IOCTL detaches the debugger/debugged process from the H/W
      Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL.
      
      - AMDKFD_IOC_DBG_ADDRESS_WATCH:
      
      This IOCTL allows to set different watchpoints with various conditions as
      indicated by the IOCTL's arguments. The available number of watchpoints
      is retrieved from topology. This operation is confined to the current
      debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER.
      
      - AMDKFD_IOC_DBG_WAVE_CONTROL:
      
      This IOCTL allows to control a wavefront as indicated by the IOCTL's
      arguments. For example, you can halt/resume or kill either a
      single wavefront or a set of wavefronts. This operation is confined to
      the current debugged process, which was registered through
      AMDKFD_IOC_DBG_REGISTER.
      
      Because the arguments for the address watch IOCTL and wave control IOCTL
      are dynamic, meaning that they could vary in size, the userspace passes a
      pointer to a structure (in userspace) that contains the value of the
      arguments. The kernel driver is responsible to parse this structure and
      validate its contents.

      Fixes for 4.2. Nothing too serious (given that it's still pre merge
      window). With that it's off for 2 weeks of vacation for me and taking care
      of 4.2 fixes for Jani.

      drm/ttm: dma: Don't crash on memory in the vmalloc range · 1c34d824
      Alexandre Courbot authored
      dma_alloc_coherent() can return memory in the vmalloc range.
      virt_to_page() cannot handle such addresses and crashes. This
      patch detects such cases and obtains the struct page * using
      vmalloc_to_page() instead.

      Pull vfs fix from Al Viro:
       "Off-by-one in d_walk()/__dentry_kill() race fix.
      
        It's very hard to hit; possible in the same conditions as the original
        bug, except that you need the skipped branch to contain all the
        remaining evictables, so that the d_walk()-calling loop in
        d_invalidate() decides there's nothing more to do and doesn't go for
        another pass - otherwise that next pass will sweep the sucker.
      
        So it's not too urgent, but seeing that the fix is obvious and the
        original commit has spread into all -stable branches..."

         - regression fix related to the big fabric API registration changes
           and configfs_depend_item() usage, that required cherry-picking one
           of HCH's patches from for-next to address the issue for v4.1 code.
      
         - remaining TCM-USER -v2 related changes to enforce full CDB
           passthrough from Andy + Ilias.
      
        Also included is a target_core_pscsi driver fix from Andy that
