Subject: [Devel] iasl -d and duplicate symbols (ACPI Error:
AE_ALREADY_EXISTS)
Hi all,
I am trying to patch the ACPI tables on my Dell XPS 15 9570 running FreeBSD
13.0-CURRENT @ git commit 68c8581f772. 'acpidump -d -t' gives error
AE_ALREADY_EXISTS when trying to add symbol
\_SB.PCI0.XHC.RHUB.HS01._UPC.?? Google says this is because my BIOS' set
of ACPI tables contains two duplicate tables, and it fails to add symbols from
the 2nd table because they already exist from the 1st.

Hi,
Q: By "duplicate table", does this mean the entire body of the table
(excluding its header) is duplicated?
It depends. A single table can declare multiple named objects. This message
indicates that these symbols have been declared in multiple tables. If the
entire body of the table is duplicated you should get a lot of these errors.
However, it does not necessarily mean that there are duplicate tables. Some
content may be different.
Okay, thanks.?? Understand I'm only talking about the extraction and
decompilation of the ACPI tables /after/ booting, _not_ the FreeBSD
kernel's acpica implementation parsing those tables during boot
(although I'm sure they probably both use the same underlying
functions).?? The command-line decompiler, 'iasl -d', stops with error
when hitting the first duplicate symbol, but the kernel boot process
trudges on.
What's the standard practice for handling this error? I assume I have to:
In order to solve this issue, it must be done in the firmware. Please make sure
that you have the latest firmware from dell.
I updated to BIOS rev 1.10.1 dated 2019-04-30 last night
(https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverid=kkwch&oscode=biosa&productcode=xps-15-9570-laptop).
Same error using iasl -d / acpidump -d -t.
Once you do, please attach a dmesg of free BSD booting with the latest
firmware. The dmesg should also contain these ACPI errors.
Done. http://www.qtchat.org/~ajenkins/dmesg.today

There are similar issues with Linux that I've been seeing but I would like to
make sure that you have their latest firmware before involving dell...
I don't think I understand involving Dell at all. Granted, I would LOVE
to enjoin Dell to fix their firmware, but large computer manufacturer
historically could care less about my open-source OS' acpica symbol
parsing errors.?? I thought that because of this, the general process for
us open-source folks was to disassemble their buggy ACPI tables, patch
them, reassemble them and tell the kernel to parse those fixed tables
instead of the resident buggy ones.
https://docs.freebsd.org/doc/handbook/acpi-overview.html - 11.13.3
Overriding the Default AML
1. Identify the two duplicate tables
2. Tell 'iasl -d' (which is what 'acpidump' calls to do the
disassembly) to exclude one of the two tables
I have no idea how to do either of these two tasks with the set of acpica tools
I have (iasl version 20190108)...anyone have any pointers?
Is there a way to extract (using acpica tools) the body of a single named ACPI
table?
No
I have some ideas for patches to acpica to help with this increasingly common
issue:
* Patch iasl(1) to emit more information about the origins of the
symbols it parses, such that an AE_ALREADY_EXISTS error would also
emit the origin (table name) of the existing symbol and that of the
current table it's trying to add.
* Patch iasl(1) to add a user option (flag) to ignore tables with
duplicate symbols, possibly adding a parameter indicating number of
duplicates or percentage of duplication before dropping that table.
Would any/all of these patches be useful/considered for acceptance into
acpica?
Possibly, I think the second option hides things from the user which can be
even more confusing.
Right, the second option would purposely ignore duplicate symbols (in
iasl(8) only) just so the user can get some disassembled AML to try to
patch.?? (aside: I'd modify that option's granularity to ignore
individual duplicate symbols, not whole tables with duplicate symbols.)??
Right now the tool throws up its hands at the first symbol collision and
I get nothing.?? As an option to the command-line tool, the user has to
choose to specify it, meaning he/she chooses to ignore those collisions.
Again, my hope was to patch the buggy ACPI tables by disassembling them
with the command-line tool, reassembling them and passing the patched
tables to the kernel at boot time.?? I can't even get iasl(8) to give me
the table code because of the symbol collisions.
First option seems better but it might be non-trivial. I'll bring it up with
Bob.
Depends on there being metadata associated with each symbol.?? If the
table origin of each symbol isn't in there already, I'd just have to add
each parsed table to a dynamic list of origins, then add a pointer to
the current table being parsed to each parsed symbol's metadata.?? A
collision error (AE_ALREADY_EXISTS) would follow the existing symbol's
pointer to its origin table and print that in the error message;
similarly with the symbol that's being added.
Thanks again for your response!
Anthony
I hope this helps. Let me know if you have any other questions
