      drm/i915/ehl: Don't forget to handle port C's hotplug interrupts · 8ef7e340
      Matt Roper authored
      We're mostly re-using ICL's interrupt handling on EHL, but we still need
      to remember to account for the extra combo port that EHL has.  Use TGP's
      mask (which includes combo port C) rather than ICP's mask when
      appropriate.  Let's also skip reading TC-specific registers on this
      platform since EHL doesn't have any TC ports.
      
      v2: Base setup of SHOTPLUG_CTL_TC on whether the tc pin mask is non-zero
          rather than performing another PCH type check.  (Jose)

      drm/i915/oa: add content to Makefile · 8ad4ca6e
      Jani Nikula authored
      Apparently the empty Makefile has caused some confusion. Add the
      subdir-cc-flags-y as in 7fcc7ca5 ("drm/i915: add header search path
      to subdir Makefiles") which should be useful.
      
      The generated headers still aren't self-contained, so can't add that.

      drm/i915: fix possible memory leak in intel_hdcp_auth_downstream() · de70fdd7
      Wei Yongjun authored
      'ksv_fifo' is malloced in intel_hdcp_auth_downstream() and should be
      freed before leaving from the error handling cases, otherwise it will
      cause memory leak.

      drm/i915/execlists: Always clear pending&inflight requests on reset · 10e36489
      Chris Wilson authored
      If we skip the reset as we found the engine inactive at the time of the
      reset, we still need to clear the residual inflight & pending request
      bookkeeping to reflect the current state of HW.
      
      Otherwise, we may end up stuck in a loop like:
