<pre>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 */
INTEL_I830,
INTEL_I845G,
INTEL_I85X,
INTEL_I865G,
/* gen3 */
INTEL_I915G,
INTEL_I915GM,
INTEL_I945G,
INTEL_I945GM,
INTEL_G33,
INTEL_PINEVIEW,
/* gen4 */
INTEL_I965G,
INTEL_I965GM,
INTEL_G45,
INTEL_GM45,
/* gen5 */
INTEL_IRONLAKE,
/* gen6 */
INTEL_SANDYBRIDGE,
/* gen7 */
INTEL_IVYBRIDGE,
INTEL_VALLEYVIEW,
INTEL_HASWELL,
/* gen8 */
INTEL_BROADWELL,
INTEL_CHERRYVIEW,
/* gen9 */
INTEL_SKYLAKE,
INTEL_BROXTON,
INTEL_KABYLAKE,
INTEL_GEMINILAKE,
INTEL_COFFEELAKE,
/* gen10 */
INTEL_CANNONLAKE,
