      drm/i915: Make sure we have enough memory bandwidth on ICL · c457d9cf
      Ville Syrjälä authored
      ICL has so many planes that it can easily exceed the maximum
      effective memory bandwidth of the system. We must therefore check
      that we don't exceed that limit.
      
      The algorithm is very magic number heavy and lacks sufficient
      explanation for now. We also have no sane way to query the
      memory clock and timings, so we must rely on a combination of
      raw readout from the memory controller and hardcoded assumptions.
      The memory controller values obviously change as the system
      jumps between the different SAGV points, so we try to stabilize
      it first by disabling SAGV for the duration of the readout.
      
      The utilized bandwidth is tracked via a device wide atomic
      private object. That is actually not robust because we can't
      afford to enforce strict global ordering between the pipes.
      Thus I think I'll need to change this to simply chop up the
      available bandwidth between all the active pipes. Each pipe
      can then do whatever it wants as long as it doesn't exceed
      its budget. That scheme will also require that we assume that
      any number of planes could be active at any time.
      
      TODO: make it robust and deal with all the open questions
      
      v2: Sleep longer after disabling SAGV
      v3: Poll for the dclk to get raised (seen it take 250ms!)
          If the system has 2133MT/s memory then we pointlessly
          wait one full second :(
      v4: Use the new pcode interface to get the qgv points rather
          that using hardcoded numbers
      v5: Move the pcode stuff into intel_bw.c (Matt)
          s/intel_sagv_info/intel_qgv_info/
          Do the NV12/P010 as per spec for now (Matt)
          s/IS_ICELAKE/IS_GEN11/
      v6: Ignore bandwidth limits if the pcode query fails

      drm/i915/icl: Fix AUX-B HW not done issue w/o AUX-A · 4361ccac
      Imre Deak authored
      Atm AUX-B transfers can fail with the following error if AUX-A is not
      enabled:

      Ville noticed this issue already earlier and managed to work around it
      by keeping AUX-A always powered whenever AUX-B was used. He also
      reported the issue to HW folks and they have now root caused the problem
      and updated BSpec with a fix (see internal BSpec/Index/21257,
      HSD/1607152412).
      
      I noticed the same error - even with the WA being applied - while doing
      AUX transfers with Chamelium being connected with a DP cable to the
      source but letting Chamelium imitate an unplug. This is probably some
      unstandard way on Chamelium's behalf of disconnecting itself from the
      AUX pins. For instance it could still pull on the AUX pins which would
      prevent the source from detecting AUX timeouts in the proper way,
      leading to the ERRORs or WARNs seen in the logs in the Reference: bug
      below.
      
      In case I disconnect the sink properly (the cable itself, not via the
      Chamelium unplug xmlrpc command) then the AUX timeout signaling works
      properly and so there won't be any ERRORs/WARNs emitted.

      drm/i915: make REG_BIT() and REG_GENMASK() work with variables · 591d4dc4
      Jani Nikula authored
      REG_BIT() and REG_GENMASK() were intended to work with both constant
      expressions and otherwise, with the former having extra compile time
      checks for the bit ranges. Incredibly, the result of
      __builtin_constant_p() is not an integer constant expression when given
      a non-constant expression, leading to errors in BUILD_BUG_ON_ZERO().
      
      Replace __builtin_constant_p() with the __is_constexpr() magic spell.

      tracing: Silence GCC 9 array bounds warning · 0c97bf86
      Miguel Ojeda authored
      Starting with GCC 9, -Warray-bounds detects cases when memset is called
      starting on a member of a struct but the size to be cleared ends up
      writing over further members.
      
      Such a call happens in the trace code to clear, at once, all members
      after and including `seq` on struct trace_iterator:
      
          In function 'memset',
              inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
          ./include/linux/string.h:344:9: warning: '__builtin_memset' offset
          [8505, 8560] from the object at 'iter' is out of the bounds of
          referenced subobject 'seq' with type 'struct trace_seq' at offset
          4368 [-Warray-bounds]
            344 |  return __builtin_memset(p, c, size);
                |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      In order to avoid GCC complaining about it, we compute the address
      ourselves by adding the offsetof distance instead of referring
      directly to the member.
      
      Since there are two places doing this clear (trace.c and trace_kdb.c),
      take the chance to move the workaround into a single place in
      the internal header.
