回复: [edk2-devel] [PATCH] uefi-sct/SctPkg:Enhance BBTestReadKeyStrokeExFunctionAutoTestCheckpoint1()

Hi Sunny,

Thanks for clarification. I will update the patch to make test fail when
KeyState is not touched.

Thanks
Barton

BBTestReadKeyStrokeExFunctionAutoTestCheckpoint1()

Hi Barton,

As our discussion in today's edk2-test bug triage meeting, my second point "
UEFI spec implies that the ReadKeyStrokeEx should clear KeyState (set the
value to zero) if there is no key data" is not clear enough. Sorry about
that.

To be clear, UEFI spec says the following:
- UEFI drivers which implement the EFI_SIMPLE_TEXT_INPUT_EX protocol are
required to return KeyData.Key and KeyData.KeyState values. These drivers
must always return the most current state of KeyData.KeyState.KeyShiftState
and KeyData.KeyState.KeyToggleState.
However, when user doesn't press any key, there will be no most current
state to return. For solving thie problems, @Ruiyu Ni (In Cc) has patch
series https://edk2.groups.io/g/devel/message/20311 and commit message
below:
- Today's implementation only return key state when there is a key.But when
user doesn't press any key, the key state cannot be returned.The patch
changes the ReadKeyStrokeEx() to always return the key state even there is
no key pressed.

Therefore, this is just preferred implementation rather than a requirement
in spec.

Best Regards,
Sunny

BBTestReadKeyStrokeExFunctionAutoTestCheckpoint1()

Sorry for the late review.

The change looks fine. However, I'm confused about the comment " Log the
error here and return key states are not supported when high order bit of
KeyToggleState is 0 or KeyState not touched". It looks like returning
EFI_UNSUPPORTED won't log any error/failure in the result log. Did I
overlook anything here?

Furthermore, it looks like UEFI spec implies that the ReadKeyStrokeEx should
clear KeyState (set the value to zero) if there is no key data. There is
also a code change for doing this in edk2.
https://edk2.groups.io/g/devel/message/20311
Therefore, if I didn't overlook anything here, we should separately deal
with the "(Key.KeyState.KeyShiftState == 0xFFFFFFFF) ||
(Key.KeyState.KeyToggleState == 0xFF)" as a failure rather than directly
returning EFI_UNSUPPORTED.

Barton and Edhaya, what do you guys think?

Best Regards,
Sunny

BBTestReadKeyStrokeExFunctionAutoTestCheckpoint1()

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2386

Enhance BBTestReadKeyStrokeExFunctionAutoTestCheckpoint1()
to handle ReadKeyStrokeEx implementation which returns EFI_NOT_READY
but without touching KeyToggleState.
