[v6,0/3] cec: Deck Control tests

Message

Deborah Brouwer June 10, 2021, 11:58 p.m. UTC

This is part of an Outreachy project to expand the testing of
Deck Control messages as handled by CEC adapters.

Changes since v5:
	cec-compliance:
	- check for Feature Abort before getting deck status.
	cec-follower:
	- send updates to the logical address of the device that
		requested ongoing status updates which may be
		different from the device that requests deck status
		on a one-time basis.

Changes since v4:
	cec-compliance:
	- Change deck_status to a reference and initialize to 0.
	- Revise test results after receiving Feature Abort with
		Incorrect Mode.
	- Simplify for loop for Skip Forward and Reverse.
	- Remove Play as a possible response to Eject.
	- Rename "match" and its argument,  add fail on abort.
	- Rearrange play tests to see clearly all three options
		(MIN/MED/MAX).
	cec-follower:
	- Set deck_skip_start to 0 if a new command or standby occurs
		in the interval between Skip Forward/Reverse and Play.
	- Move skip timer to the end of while loop in testProcessing.
	- Add helper function update_deck_state.

Changes since v3:
	cec-compliance:
		- Stop using REQ_On for monitoring deck status changes; 
			instead add a helper function to get and return deck status.
		- Allow Stop or Eject to return Feature Abort, Incorrect Mode.
		- Replace passive util_receive with an active deck query to see
			if the deck status changes to Play after Skip Forward/Reverse.
		- Add helper function to match play mode and expected deck status.
		- Remove the Deck Status test.
	cec-follower:
		- Track the elasped time since Skip Forward/Reverse and Play after 2s.
		- Remove tray open/close toggle from Eject

Changes since v2:
	cec-compliance:
		- If a deck returns Feature Abort, Incorrect Mode, just provide info
			unless the deck actually has media, then issue a warning.
		- If a deck reports Skip Forward/Reverse status, wait until the status
			changes again before resuming testing to avoid prematurely
			failing the test.
		- Rearrange/change the tests to trigger deck status changes.
	cec-follower:
		- Only report actual status changes, not just every Deck Control
			message that is processed.
		- Send Skip Forward/Reverse and then sleep 2 seconds before
			sending Play.
		- Remove the toggle between Play Forward/Play Still.

Changes since v1:
	- Remove unnecessary functions and node states.
	- Assume that media is present and use the "No Media"
		deck state solely to indicate whether the tray is open.
	- Change and add invalid operands so operands just
		outside of the valid range are tested.
	- Remove restriction to playback/record device.
