drm/i915: Read graphics/media/display arch version from hw
Going forward, the hardware teams no longer consider new platforms to have a "generation" in the way we've defined it for past platforms. Instead, each IP block (graphics, media, display) will have their own architecture major.minor versions and stepping ID's which should be read directly from a register in the MMIO space. Bspec: 63361, 64111 v2: - Move the IP version readout to intel_device_info.c - Convert the macro into a function v3: - Move subplatform init to runtime early init - Cache runtime ver, release info to compare with hardware values. - Use IP_VER for snaity check(MattR) v4: - Minor doccumentation changes. - Normalize HAS_GMD_ID macro value.(JaniN) Signed-off-by: Matt Roper <[email protected]> Signed-off-by: Rodrigo Vivi <[email protected]> Reviewed-by: Lucas De Marchi <[email protected]> Signed-off-by: Radhakrishna Sripada <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
