drm/i915/fbc: Move FBC debugfs stuff into intel_fbc.c

2021-12-03T11:12:47Z

In order to encapsulate FBC harder let's just move the debugfs stuff into intel_fbc.c. Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20211124113652.22090-12-ville.syrjala@linux.intel.com Acked-by: Jani Nikula

drm/i915/fbc: Pass i915 instead of FBC instance to FBC underrun stuff

2021-12-03T11:12:30Z

The underrun code doesn't need to know any details about FBC, so just pass in the whole device rather than a specific FBC instance. We could make this a bit more fine grained by also passing in the pipe to intel_fbc_handle_fifo_underrun_irq() and letting the FBC code figure which FBC instance (if any) is active on said pipe. But that seems a bit overkill for this so don't bother.

drm/i915/debugfs: move debug printing to intel_display_power.c

The debugfs should have no special privileges to look into the implementation guts. Move the actual debug printing of power domains to intel_display_power.c.

drm/i915/fbc: Start passing around intel_fbc

2021-11-11T13:18:11Z

In preparation for multiple FBC instances start passing around intel_fbc pointers rather than i915 pointers. And once there are multiple of these we can't rely on container_of() to get back to the i915, so we toss in a fbc->i915 pointer already.

drm/i915/display: Wait PSR2 get out of deep sleep to update pipe

2021-10-26T17:30:51Z

Alderlake-P was getting 'max time under evasion' messages when PSR2 is enabled, this is due PIPE_SCANLINE/PIPEDSL returning 0 over a period of time longer than VBLANK_EVASION_TIME_US. For PSR1 we had the same issue so intel_psr_wait_for_idle() was implemented to wait for PSR1 to get into idle state but nothing was done for PSR2. For PSR2 we can't only wait for idle state as PSR2 tends to keep into sleep state(ready to send selective updates). Waiting for any state below deep sleep proved to be effective in avoiding the evasion messages and also not wasted a lot of time. v2: - dropping the additional wait_for loops, only the _wait_for_atomic() is necessary - waiting for states below EDP_PSR2_STATUS_STATE_DEEP_SLEEP v3: - dropping intel_wait_for_condition_atomic() function Cc: Ville Syrjälä Cc: Gwan-gyeong Mun Signed-off-by: José Roberto de Souza Reviewed-by: Gwan-gyeong Mun Link: https://patchwork.freedesktop.org/patch/msgid/20211005231851.67698-1-jose.souza@intel.com

drm/i915: split out vlv sideband to a separate file

The VLV/CHV sideband code is pretty distinct from the rest of the sideband code. Split it out to new vlv_sideband.[ch]. Pure code movement with relevant #include changes, and a tiny checkpatch fix on top.

drm/i915/mst: abstract intel_dp_mst_source_support()

2021-10-08T10:14:25Z

Add a function for checking source MST support. Drop intel_dp->can_mst and use intel_dp->mst_mgr.cbs to indicate the same. It's the single point of truth without additional state variables. In code, "source support" is also self-documenting as opposed to the vague "can mst".
