On GFX9+, format modifiers are always enabled and ensure the
frame-buffers can be scanned out at ADDFB2 time.
On GFX8-, format modifiers are not supported and no other check
is performed. This means ADDFB2 IOCTLs will succeed even if the
tiling isn't supported for scan-out, and will result in garbage
displayed on screen [1].
Fix this by adding a check for tiling flags for GFX8 and older.
The check is taken from radeonsi in Mesa (see how is_displayable
is populated in gfx6_compute_surface).

ASSR is dependent on Signed PSP Verstage to enable Content
Protection for eDP panels. Unsigned PSP verstage is used
during development phase causing ASSR to FAIL.
As a result, link training is performed with
DP_PANEL_MODE_DEFAULT instead of DP_PANEL_MODE_EDP for
eDP panels that causes display flicker on some panels.
[How]
- Do not change panel mode, if ASSR is disabled
- Just report and continue to perform eDP link training
with right settings further.

It seems a positive dentry in kernfs becomes a negative dentry directly
through d_delete() in vfs_rmdir(). dentry->d_time is uninitialized
when accessing it in kernfs_dop_revalidate(), because it is only
initialized when created as negative dentry in kernfs_iop_lookup().
The problem can be reproduced by the following command:
cd /sys/fs/cgroup/pids && mkdir hi && stat hi && rmdir hi && stat hi
A simple fixes seems to be initializing d->d_time for positive dentry
in kernfs_iop_lookup() as well. The downside is the negative dentry
will be revalidated again after it becomes negative in d_delete(),
because the revison of its parent must have been increased due to
its removal.
Alternative solution is implement .d_iput for kernfs, and assign d_time
for the newly-generated negative dentry in it. But we may need to
take kernfs_rwsem to protect again the concurrent kernfs_link_sibling()
on the parent directory, it is a little over-killing. Now the simple
fix is chosen.

unix_create1() returns NULL on error, and the callers assume that it never
fails for reasons other than out of memory. So, the callers always return
-ENOMEM when unix_create1() fails.
However, it also returns NULL when the number of af_unix sockets exceeds
twice the limit controlled by sysctl: fs.file-max. In this case, the
callers should return -ENFILE like alloc_empty_file().
This patch changes unix_create1() to return the correct error value instead
of NULL on error.
Out of curiosity, the assumption has been wrong since 1999 due to this
change introduced in 2.2.4 [0].

Originally, get_abi.pl was using spaces to separate What: parameters,
but there are several references that declare things like:
/sys/class/powercap/.../<power zone>/enabled
So, the logic was changes in order to properly address it.
That broke the second What added by
Changeset 18e49b304633 ("ABI: security: fix location for evm and ima_policy").
As the only file that defines multiple What: at the same line is
this file, let's move the second What: to a separate line.
Fixes: 18e49b304633 ("ABI: security: fix location for evm and ima_policy")
Fixes: ab9c14805b37 ("scripts: get_abi.pl: Better handle multiple What parameters")

As parsing the sysfs entries can take a long time, add
progress information.
The progress logic will update the stats on every second,
or on 1% steps of the progress.
When STDERR is a console, it will use a single line, using
a VT-100 command to erase the line before rewriting it.
Otherwise, it will put one message on a separate line.
That would help to identify what parts of sysfs checking
that it is taking more time to process.

The current highlight schema is not working properly. So, use,
instead, Pod::Text.
While here, also update the copyright in order to reflect the latest
changes and the e-mail I'm currently using.

It doesn't make any sense to parse ABI entries under
/sys/firmware, as those are either specified by ACPI specs
or by Documentation/devicetree.
The current logic to ignore firmware entries is incomplete,
as it ignores just the relative name of the file, and not
its absolute name. This cause errors while parsing the
symlinks.
So, rewrite the logic for it to do a better job.
Tested with both x86 and arm64 (HiKey970) systems.

The logic under graph_add_file should create, for every entry, a
__name name array for all entries of the tree. If this fails, the
symlink parsing will break.
Add an error if this ever happens.
While here, improve the output of data dumper to be more
compact and to avoid displaying things like $VAR1=.
