[igt-dev] [PATCH i-g-t 0/2] tests/kms_chamelium Handle DP FSM more reliably

[Kunal Joshi]

Receiver reset is always required after we set a new mode, so let's disable
the mode (reset_state() does that) before we switch to a new mode.
With this we will get the HPD pulses reliably for each iteration over
all the supoprted modes.

Please refer to commits using this format:

c8dc1fd926a5 ("tests/kms_chamelium: Capture on type-c")

You can get that easily with:
   git log -1 --abbrev=12 --format='%h ("%s")' $SHA1

Pretty much the same treatment you gave the other subtests in the
mentioned commit, looks straightforward

[igt-dev] [PATCH i-g-t 0/2] tests/kms_chamelium Handle DP FSM more reliably

[Kunal Joshi]

Receiver reset is always required after we set a new mode, so let's disable
the mode (reset_state() does that) before we switch to a new mode.
With this we will get the HPD pulses reliably for each iteration over
all the supoprted modes.
