      drm/i915: add some assertions about VBT DDI port types · 554d6af5
      Paulo Zanoni authored
      Our code makes a lot of assumptions regarding what each DDI port
      actually supports, and the VBT should tell us what is really happening
      in the hardware. So parse the information provided by the VBT and
      check if any of our assumptions is wrong.
      
      Our driver also has a history of not really trusting the VBT, so a
      WARN here could mean that:
       a) our coding assumptions are wrong
       b) the VBT is wrong
       c) we're incorrectly parsing the VBT
       d) the checks are wrong
      
      But I really hope we won't ever trigger any of those WARNs.
      
      v2: Don't check the redundant "Capabilities" field from byte 24 since
          it doesn't seem to be used.
      v3: Rebase
      v4: Replace WARN with DRM_DEBUG_KMS

      drm/i915: check the DDC and AUX bits of the VBT on DDI machines · 6bf19e7c
      Paulo Zanoni authored
      Our code currently assumes that port X will use the DP AUX channel X
      and the DDC pin X. The VBT should tell us how things are mapped, so
      add some WARNs in case we discover our assumptions are wrong (or in
      case the VBT is just wrong, which is also perfectly possible).
      
      Why would someone wire port B to AUX C and DDC D?

      drm/i915: use the HDMI DDI buffer translations from VBT · 6acab15a
      Paulo Zanoni authored
      We currently use the recommended values from BSpec, but the VBT
      specifies the correct value to use for the hardware we have, so use
      it. We also fall back to the recommended value in case we can't find
      the VBT.
      
      In addition, this code also provides some infrastructure to parse more
      information about the DDI ports. There's a lot more information we
      could extract and use in the future.
      
      v2: - Move some code to init_vbt_defaults.
      v3: - Rebase
          - Clarify the "DVO Port" matching code

      drm/i915: VBT's child_device_config changes over time · 768f69c9
      Paulo Zanoni authored
      We currently treat the child_device_config as a simple struct, but
      this is not correct: new BDB versions change the meaning of some
      offsets, so the struct needs to be adjusted for each version.
      
      Since there are too many changes (today we're in version 170!), making
      a big versioned union would be too complicated, so child_device_config
      is now a union of 3 things: (i) a "raw" byte array that's safe to use
      anywhere; (ii)  an "old" structure that's the one we've been using and
      should be safe to keep in the SDVO and TV code; and (iii) a "common"
      structure that should contain only fields that are common for all the
      known VBT versions.

      drm/i915: Use unsigned for overflow checks in execbuf · b205ca57
      Daniel Vetter authored
      There's actually no real risk since we already check for stricter
      constraints earlier (using UINT_MAX / sizeof (struct
      drm_i915_gem_exec_object2) as the limit). But in eb_create we use
      signed integers, which steals a factor of 2. Luckily struct
      drm_i915_gem_exec_object2 for this to not matter.
      
      Still, be consistent and use unsigned integers.
      
      Similar use unsinged integers when checking for overflows in the
      relocation entry processing.
      
      I've also added a new subtests to igt/gem_reloc_overflow to also
      test for overflowing args->buffer_count values.
      
      v2: Give the variables again tighter scope to make it clear that the
      computation is purely local and doesn't leak out to the 2nd block.
      Requested by Chris Wilson.

      drm/i915: Ditch INTELFB_CONN_LIMIT · 955382f3

      And the gratious overallocation of crtcs. Seems to go back to the ums
      days of yonder ...
      
      We also still need it to make the fbdev emulation happy, but I don't
      think there's really a need. Especially since the current fbdev
      emulation doesn't actually support cloning.

      drm/i915: Use kcalloc more · a1e22653
      Daniel Vetter authored
      No buffer overflows here, but better safe than sorry.
      
      v2:
      - Fixup the sizeof conversion, I've missed the pointer deref (Jani).
      - Drop the redundant GFP_ZERO, kcalloc alreads memsets (Jani).
      - Use kmalloc_array for the execbuf fastpath to avoid the memset
        (Chris). I've opted to leave all other conversions as-is since they
        aren't in a fastpath and dealing with cleared memory instead of
        random garbage is just generally nicer.

      Done while reviewing all our allocations for fubar. Also a few errant
      cases of lacking () for the sizeof operator - just a bit of OCD.

      - Basic mipi dsi support from Jani. Not yet converted over to drm_bridge
        since that was too fresh, but the porting is in progress already.
      - More vma patches from Ben, this time the code to convert the execbuffer
        code. Now that the shrinker recursion bug is tracked down we can move
        ahead here again. Yay!
      - Optimize hw context switching to not generate needless interrupts (Chris
        Wilson). Also some shuffling for the oustanding request allocation.
      - Opregion support for SWSCI, although not yet fully wired up (we need a
        bit of runtime D3 support for that apparently, due to Windows design
        deficiencies), from Jani Nikula.
      - A few smaller changes all over.

      While this code is fixable, the commit itself fails on several levels:
      
       - it should have been a separate helper function
       - why the heck does it do strchr() twice
       - it casts a const char * over into char *
       - sloppy style
       - it's not even a regression fix!
      
      So lets revert it and re-try the patch in v3.13.
