2020-02-13drm/i915: Convert to CRTC VBLANK callbacksThomas Zimmermann1-4/+2
VBLANK callbacks in struct drm_driver are deprecated in favor of their equivalents in struct drm_crtc_funcs. Convert i915 over. The callback struct drm_driver.get_scanout_position() is deprecated in favor of struct drm_crtc_helper_funcs.get_scanout_position(). i915 doesn't use CRTC helpers. Instead pass i915's implementation of get_scanout_position() to DRM core's drm_crtc_vblank_helper_get_vblank_timestamp_internal(). v3: * rename dcrtc to _crtc * use intel_ prefix for i915_crtc_get_vblank_timestamp() * update for drm_crtc_vblank_helper_get_vblank_timestamp_internal() v2: * use DRM's implementation of get_vblank_timestamp() * simplify function names Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200123135943.24140-8-tzimmermann@suse.de
2019-10-26drm/i915: Extract the GuC interrupt handlersAndi Shyti1-9/+0
Pull the GuC interrupt handlers out of i915_irq.c. They now use the GT interrupt facilities rather than the central dispatch. Based on a patch by Chris Wilson.

2019-10-26drm/i915: Extract GT render power state managementAndi Shyti1-3/+0
i915_irq.c is large. One reason for this is that has a large chunk of the GT render power management stashed away in it. Extract that logic out of i915_irq.c and intel_pm.c and put it under one roof.

2019-10-04drm/i915: Implement a better i945gm vblank irq vs. C-states workaroundVille Syrjälä1-2/+2
The current "disable C3+" workaround for the delayed vblank irqs on i945gm no longer works. I'm not sure what changed, but now I need to also disable C2. I also got my hands on a i915gm machine that suffers from the same issue. After some furious poking of registers I managed to find a better workaround: The "Do not Turn off Core Render Clock in C states" bit. With that I no longer have to disable any C-states, and as a nice bonus the power cost is only ~1/4 of the "disable C3+" method (which mind you doesn't even work anymore, and so would have an even higher power cost if we made it work by also disabling C2). So let's throw out all the cpuidle/qos crap and just toggle the magic bit as needed. And we extend the workaround to cover i915gm as well.

2019-04-30drm/i915: extract i915_irq.h from intel_drv.h and i915_drv.hJani Nikula1-0/+114
It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.
