      drm/amdkfd: Add address watch operation to debugger · e2e9afc4
      Yair Shachar authored
      The address watch operation gives the ability to specify watch points
      which will generate a shader breakpoint, based on a specified single
      address or range of addresses.
      
      There is support for read/write/any access modes.

      drm/amdkfd: Add wave control operation to debugger · 788bf83d
      Yair Shachar authored
      The wave control operation supports several command types executed upon
      existing wave fronts that belong to the currently debugged process.
      
      The available commands are:
      
      HALT   - Freeze wave front(s) execution
      RESUME - Resume freezed wave front(s) execution
      KILL   - Kill existing wave front(s)

      drm/amdkfd: Add skeleton H/W debugger module support · fbeb661b
      Yair Shachar authored
      This patch adds the skeleton H/W debugger module support. This code
      enables registration and unregistration of a single HSA process at a
      time.
      
      The module saves the process's pasid and use it to verify that only the
      registered process is allowed to execute debugger operations through the
      kernel driver.

      drm/amdkfd: Add static user-mode queues support · 992839ad
      Yair Shachar authored
      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
      number of HQDs (Hardware Queue Descriptors).

      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.

      drm/i915: Return the frontbuffer flip to enable intel_crtc_enable_planes. · 2d847d45
      Rodrigo Vivi authored
      Without this frontbuffer flip when enabling planes PSR got compromised
      and wasn't being enabled waiting forever on the flush that never
      arrived.
      
      Another solution would to create a enable_cursor function and split this
      frontbuffer flip among the different plane enable and disable functions.
      But if necessary this can be done in a follow up work. For now let's
      just fix the regression.

      radeon: Deinline indirect register accessor functions · 9e5acbc2
      Denys Vlasenko authored
      This patch deinlines indirect register accessor functions.
      
      These functions perform two mmio accesses, framed by spin lock/unlock.
      Spin lock/unlock by itself takes more than 50 cycles in ideal case
      (if lock is exclusively cached on current CPU).
      
      With this .config: http://busybox.net/~vda/kernel_config,
      after uninlining these functions have sizes and callsite counts
      as follows:
      
      r600_uvd_ctx_rreg: 111 bytes, 4 callsites
      r600_uvd_ctx_wreg: 113 bytes, 5 callsites

      eg_cg_wreg: 108 bytes, 52 callsites
      
      Functions r100_mm_rreg() and r100_mm_rreg() have a fast path and
      a locked (slow) path. This patch deinlines only slow path.

          drm/i915: disable IPS while getting the pipe CRCs.
      
      For some unknown reason, when IPS gets enabled, the sink CRC changes.
      Since hsw_enable_ips() doesn't really guarantee to enable IPS (it
      depends on package C-states), we can't really predict if IPS is
      enabled or disabled while running our CRC tests, so let's just
      completely disable IPS while sink CRCs are being used.
      
      If we find a way to make IPS not change the pipe CRC result, we may
      want to fix IPS and then revert this patch (and 8c740dce too). While
      this doesn't happen, let's merge this patch, so the IGT tests relying
      on sink CRCs can work properly.
      
      This was discovered while developing a new IGT test, which will
      probably be called kms_frontbuffer_tracking.
      
      Testcase: igt/kms_frontbuffer_tracking (not on upstream IGT yet)

      Ville has patches to fix it all up properly, but unfortunately they're
      stuck in review limbo. And since the 4.2 feature cutoff has passed we
      need to somehow  handle this regression.

      drm/i915: Adjust sideband locking a bit for CHV/VLV · 54433e91
      Ville Syrjälä authored
      chv_enable_pll() doesn't need to hold sb_lock for the entire duration of
      the function. Drop the lock as soon as possible.
      
      valleyview_set_cdclk() does a potential lock+unlock+lock+unlock cycle
      with sb_lock. Grab the lock a few lines earlier so we can make do
      with a single lock+unlock cycle always.

          drm/i915: Remove implicitly disabling primary plane for now
      
      but the intel_flush_primary_plane() calls were left behind. Replace them
      with straight forward POSTING_READ() of the sprite surface address
      register.
      
      The other user of intel_flush_primary_plane() is g4x_disable_trickle_feed()
      where we can just inline the steps directly.
      
      This allows intel_flush_primary_plane() to be killed off.

      drm/i915: Throw out WIP CHV power well definitions · fde61e4b
      Ville Syrjälä authored
      Expecting CHV power wells to be just an extended versions of the VLV
      power wells, a bunch of commented out power wells were added in
      anticipation when Punit folks would implement it all. Turns out they
      never did, and instead CHV has fewer power wells than VLV. Rip out all
      the #if 0'ed junk that's not needed.

      Not sure which LDO programming sequence delay should be used for the CHV
      PHY, but the spec says that 600ns is "Used by default for initial
      bringup", and the BIOS seems to use that, so let's do the same.

      It is theoretically possible that a swapped out BO gets the

      Instead just use another VA state to note updated areas.
