[edk2-devel] [PATCH v3 0/4] AndroidBootImgLib improvements

Posted by Jeff Brasen via groups.io 1 week, 4 days ago
Added support for using loadfile2 approach for passing ramdisk to linux.
Created patch series for general error handling improvments based on
review feedback.
If ACPI tables are in system table or PCD is defined the LoadFile2 method
of passing initrd will be used.

[v3]
-Code review cleanup
-Removed duplicate header file
-Added change to allow FDT to install if UpdateDtb function is not defined
-Added specific ACPI check
-Moved install functions to subfunctions

[v2]
-Added review feedback
-General improvements to error handling

[v1]
- Intial revision


Jeff Brasen (4):
  EmbeddedPkg: Remove duplicate libfdt.h include
  EmbeddedPkg: AndroidBootImgBoot error handling updates
  EmbeddedPkg: Install FDT if UpdateDtb is not present
  EmbeddedPkg: Add LoadFile2 for linux initrd

Hi Jeff,

Thanks for this.
This set looks good to me, with a slight question mark wrt behaviour
compatibility with previous versions for 3/4.
(I think it's fine, but I'm a bear of very little brain, and it's been
several years since I reviewed this code, and even longer since I
really interacted with Android.
^
| shameless plug for more EmbeddedPkg reviewer volunteers.)

I've added Jun Nie, who wrote the original version of this code, to
see if he has any comments.

1-2/4 are obviously unproblematic, and I could merge those ahead of
time if preferred. You can add
Reviewed-by: Leif Lindholm <leif@nuviainc.com>
for those if there are any further revisions of the set.

Best Regards,

Leif

Re: [edk2-devel] [PATCH v3 0/4] AndroidBootImgLib improvements

Posted by Jeff Brasen via groups.io 1 week, 4 days ago
So for patch 3: This is only a change if mAndroidBootImg->UpdateDtb == NULL.

This seemed like a bug as we would not add the initrd values nor would we use the fdt from the BootImg if that is where the device tree was sourced from.

It seems like either we should require UpdateDtb to be implemented (which seems to cause greater compatibility issues) or we install the device tree we have if that function isn't implemented.

As far as merging goes I am fine either way. Our particular flow won't hit this path as we don't have a device tree in the bootimg (use the system config table) and we will have the new pcd set, but this seemed like a bug while I looking at this code.


Thanks,

Jeff

Jun/Others,

  Any additional comments on this patch series?

Re: [edk2-devel] [PATCH v3 0/4] AndroidBootImgLib improvements

Posted by Leif Lindholm 2 days, 11 hours ago
Hi Jeff,

I was about to say "no more issues", and then I went to build
EmbeddedPkg, and it turns out this fails in
Applications/AndroidBootApp due to the missing dependency on
gEfiLoadFile2ProtocolGuid in AndroidBootImgLib.inf.

(Why this doesn't break AndroidFastbootApp build as well is not
immediately obvious to me.)

Would you like to figure out why, or would you prefer me to just fold
in

diff --git a/EmbeddedPkg/Library/AndroidBootImgLib/AndroidBootImgLib.inf b/EmbeddedPkg/Library/AndroidBootImgLib/AndroidBootImgLib.inf

That looks like something I missed and looks good, do you need me to make a v4 or will you just add that in. When I built I just used our application that has the guid in our inf so missed this.

From my looking at it AndroidFastBootApp doesn't seem to use this lib.

Re: [edk2-devel] [PATCH v3 0/4] AndroidBootImgLib improvements

Posted by Jun Nie 3 days, 19 hours ago
Hi Jeff,

I do not ever work on EDK soon after this patch set was merged.  It is
long time since then.
I am sorry that I have no comments other than no objections on your patch.

Regards,
Jun
