Re: [patch 0/3] MdeModulePkg/UiApp: Signal event when enter/exit setup menu

["Tim Lewis" <tim.lewis@insyde.com>]

If we start to see UEFI drivers that are using this, then it is a spec
issue, because it means that systems which do not implement the event will
not function correctly.

There is no need to update UEFI spec, just implementation related. It has no
impact to the modules which do not care these two events.

This is starting to sound like something that requires a UEFI spec update.

Hi all,

All setup menu enter/exit cases includes:
a.	UiApp entry point is called and then setup menu is shown
(enter setup menu) 
b.	User select Continue menu in setup menu to exit.
(exit setup menu)
c.	User select Reset menu in setup page to leave exit.
(exit setup menu)
d.	User boot from file to exit setup page.
(exit setup menu)
e.	Exit from boot from file and return to UiApp.
(enter setup menu)
f.	User boot from boot manager to exit setup page.
(exit setup menu)
g.            Exit the boot option in boot manager and return to UiApp.
(enter setup menu)

I didn't describe it in details in the commit messages.  I am sorry that if
it make you confused.
I will add them in the commit messages of V2 patches.


Thanks,
Dandan

enter/exit setup menu

Hi Mike,

We can't move the enter/exit event signaling into the FormBrowwer SendForm()
function.

Because we can't decide whether enter/exit setup through SendForm() is
called or not.  Some examples:

1. SendForm() is not called when exit setup menu and re-enter setup menu.
Such as, SendForm() is only called when enter front page firstly. But when
go to Boot Manager menu to select an option to boot and exit setup menu,
then exit the option and return to setup menu, SendForm() is not called in
this case.

2. SendForm () may be also called more than one time even if we don't  leave
setup menu. Such as, if we want to add an boot option in setup menu, when
choose file to add boot option, SendForm() will be called to show files. But
we don't  think we leave setup menu in this case.

So if we signal setup enter/exit event in SendForm(), may cause less/more
notifications. Which is not a correct behavior.


Thanks,
Dandan

Dandan Bi,

Is it possible to move the enter/exit event signaling into the FormBrowwer
SendForm() function?  The current patch set adds these signal calls in all
the places that
SendForm() is called and if one of these is missed, a notification will be
missed.

Mike
