[PATCH 1/1] efi_loader: initialize console size late

[PATCH 1/1] efi_loader: initialize console size late

[Heinrich Schuchardt]

From: Heinrich Schuchardt <xypron.glpk@gmx.de>

If CONFIG_VIDEO_DM=n we query the display size from the serial console.
Especially when using a remote console the response can be so late that
it interferes with autoboot.

Only query the console size when running an EFI binary.

Add debug output showing the determined console size.

This fixes the boot on a kontron-sl-mx8mm board accessed remotely.
The autoboot process is no longer interrupted.

Thanks a lot!

If the key part of this patch is to move query_console_size() from
efi_init_early() to efi_init_obj_list(), the to-be-fixed patch is not
the one above but
        commit a57ad20d07e8 ("efi_loader: split efi_init_obj_list() into two stages")

Moreover, this is just a warning but once Sughosh's patch,
        https://lists.denx.de/pipermail/u-boot/2022-June/485977.html
is merged and FWU_MULTI_BANK_UPDATE is enabled, the said phenomenon can
be triggered again because efi_init_obj_list(), hence query_console_size(),
will be called in board_init_r() before showing the U-Boot prompt.

Said patch made CONFIG_EFI_SETUP_EARLY=y the default.

Then we should not merge it as is.

This causes: https://source.denx.de/u-boot/u-boot/-/jobs/450891#L229
for all instances of sandbox running that test.

This is a only a bug to the test environment:

test/py/u_boot_console_base.py:110:
self.prompt_compiled = re.compile('^' + re.escape(self.prompt), 
re.MULTILINE)

There must not be any byte before the prompt on the line for the test 
environment to recognize it as a prompt.

I will look into the problem.

Best regards

Heinrich

Have you had a chance to look into this?

2022.07 is really close and it would be nice to get a fix for this regression.

Thanks

I thought this was worked around for now?  The non-testing case should
be fine again, and tests do need to do additional code to work, which is
not ideal, but good enough for the moment.

I haven't realized that the patch has been applied.

We are good now, thanks!

The patch is merged June 19th:

e05bd68ed5fc ("test: work around for EFI terminal size probing")

Why do you ask?

Because I haven't seen an "applied" message in this thread.

I see it in mainline now, thanks.
