            Bug ID: 106178
           Summary: Feature request: HDCP support for graphics platforms
                    earlier than Haswell
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org

Could the new HDCP support in the Linux i915 driver be extended to include Ivy
Bridge?

I am looking at the is_hdcp_supported() function in
drivers/gpu/drm/i915/intel_hdcp.c as an indication of what is currently
supported:

bool is_hdcp_supported(struct drm_i915_private *dev_priv, enum port port)
{
        /* PORT E doesn't have HDCP, and PORT F is disabled */
        return ((INTEL_GEN(dev_priv) >= 8 || IS_HASWELL(dev_priv)) &&
                !IS_CHERRYVIEW(dev_priv) && port < PORT_E);
}

where the platforms are listed in drivers/gpu/drm/i915/intel_device_info.h:

enum intel_platform {
        INTEL_PLATFORM_UNINITIALIZED = 0,
        /* gen2 */

        /* gen10 */                                                             
        INTEL_CANNONLAKE,
