| | | | | | | | | | | | | | | | | | | | | | | | | | | | Oneshot disabling of IPS when CRC capturing is started is insufficient. IPS may get re-enabled by any plane update, and hence tests that keep CRC capturing on across plane updates will start to see inconsistent results as soon as IPS kicks back in. Add a new knob into the crtc state to make sure IPS stays disabled as long as CRC capturing is enabled. Forcing a modeset is the easiest way to handle this since that's already how we do the panel fitter workaround. It's a little heavy handed just for IPS, but seeing as we might already do the panel fitter workaround I think it's better to follow that. We migth want to optimize both cases later if someone gets too upset by the extra delay from the modeset. v2: Check the right thing when deciding whether to force a modeset v3: Rebase, check HAS_IPS before forcing a modeset, move ips_force_disable check into pipe_config_supports_ips() Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marta Lofstedt <marta.lofstedt@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101664 Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Tested-by: Marta Lofsted <marta.lofstedt@intel.com> #v2 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170817145509.15549-1-ville.syrjala@linux.intel.com

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core provides now an ABI to userspace for generation of frame CRCs, so implement the ->set_crc_source() callback and reuse as much code as possible with the previous ABI implementation. When handling the pageflip interrupt, we skip 1 or 2 frames depending on the HW because they contain wrong values. For the legacy ABI for generating frame CRCs, this was done in userspace but now that we have a generic ABI it's better if it's not exposed by the kernel. v2: - Leave the legacy implementation in place as the ABI implementation in the core is incompatible with it. v3: - Use the "cooked" vblank counter so we have a whole 32 bits. - Make sure we don't mess with the state of the legacy CRC capture ABI implementation. v4: - Keep use of get_vblank_counter as in the legacy code, will be changed in a followup commit. v5: - Skip first frame or two as it's known that they contain wrong data. - A few fixes suggested by Emil Velikov. v6: - Rework programming of the HW registers to preserve previous behavior. v7: - Address whitespace issue. - Added a comment on why in the implementation of the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased.

* drm/i915/debugfs: Move out pipe CRC codeTomeu Vizoso2016-12-131-0/+939
In preparation to using a generic API in the DRM core for continuous CRC generation, move the related code out of i915_debugfs.c into a new file. Eventually, only the Intel-specific code will remain in this new file. v2: Rebased. v6: Rebased. v7: Fix whitespace issue. v9: Have intel_display_crc_init accept a drm_i915_private instead. v12: Rebased.
