Re: [Intel-gfx] [PATCH] drm/i915/mtl: Print SSEU information of all GTs for debugfs
The reason to dump on GTs is to make consistent SSEU information in i915. It is
fine that the information was moved to i915/gt*.

"The sseu_status debugfs has also been kept at the top level as

Do we need a consistent story across all error capture? Aka why is sseu
special.
Also the intel_gt_info_print() above calls intel_sseu_dump so we end up with
root tile SSEU printed twice?
I'm guessing this call was supposed to be deleted by 0b6613c6b91e
("drm/i915/sseu: Move sseu_info under gt_info"). We should probably go
ahead and do that now do remove the redundancy.
Okay, just need a volunteer! :)
err_print_gt_info() should be printing the GT information (including
SSEU) for whichever GT had the error. I don't see a reason why we'd
want to dump extra SSEU information for a different GT that wasn't
involved in the error.
Actually, SSEU is the _least_ useful thing to print for extra GTs
because once xehpsdv/pvc are gone from i915, the only platforms that
have multiple GTs are MTL/ARL and the SSEU information will always be
empty on the media GT (there's no DSS or EUs there).
Yes all good points. Perhaps Yu can shed more light on why the need to
dump on GTs came about?
Then, on a second look, the correct GT info is already captured. What is
missing is teaching, probably intel_gt_info_print, to skip dumping the
SSEU info on media tiles. That coupled with removing one of the
redundant calls should complete the picture. Although I don't know which
one between intel_sseu_print_topology and intel_sseu_dump to keep. Or
the data from intel_sseu_print_topology is a genuine value add on top of
intel_sseu_dump?

There possibly was a Jira years ago to do stuff about multi-tile error
capture but maybe it got lost.
