The first compatible strings added for the AXE-1-16M are not sufficient to
accurately describe all the IMG Rogue GPUs. The current "img,img-axe"
string refers to the entire family of Series AXE GPUs, but this is
primarily a marketing term and does not denote a level of hardware
similarity any greater than just "Rogue".
The more specific "img,img-axe-1-16m" string refers to individual AXE-1-16M
GPU. For example, unlike the rest of the Series AXE GPUs, the AXE-1-16M
only uses a single power domain.
The situation is actually slightly worse than described in the first
paragraph, since many "series" (such as Series BXS found in the TI AM68
among others and added later in this series) contain cores with both Rogue
and Volcanic architectures.
Besides attempting to move away from vague groupings defined only
by marketing terms, we want to draw a line between properties inherent to
the IP core and choices made by the silicon vendor at integration time.
For instance, the number of power domains is a property of the IP core,
whereas the decision to use one or multiple clocks is a vendor one.
In the original compatible strings, we must use "ti,am62-gpu" to constrain
both of these properties since the number of power domains cannot be fixed
for "img,img-axe".
Work is currently underway to add support for volcanic-based Imagination
GPUs, for which bindings will be added in "img,powervr-volcanic.yaml".
As alluded to previously, the split between rogue and volcanic cores is
non-obvious at times, so add a generic top-level "img,img-rogue" compatible
string here to allow for simpler differentiation in devicetrees without
referring back to the bindings.
The currently supported GPU (AXE-1-16M) only requires a single power
domain. Subsequent patches will add support for BXS-4-64 MC1, which has
two power domains. Add infrastructure now to allow for this.
Also allow the dma-coherent property to be added to IMG Rogue GPUs, which
are DMA devices. The decision for coherency is made at integration time and
this property should be applied wherever it accurately describes the
vendor integration.
Note that the new required properties for power domains are conditional on
the new base compatible string to avoid an ABI break.

HDMI standard defines recommended N and CTS values for Audio Clock
Regeneration. Currently each driver implements those, frequently in
somewhat unique way. Provide a generic helper for getting those values
to be used by the HDMI drivers.
The helper is added to drm_hdmi_helper.c rather than drm_hdmi_audio.c
since HDMI drivers can be using this helper function even without
switching to DRM HDMI Audio helpers.
Note: currently this only handles the values per HDMI 1.4b Section 7.2
and HDMI 2.0 Section 9.2.1. Later the table can be expanded to
accommodate for Deep Color TMDS char rates per HDMI 1.4 Appendix D
and/or HDMI 2.0 / 2.1 Appendix C).

Set default limit on the number of pixels for adapters without

just don't provide any description.

Rewrite the parser for the vendor firmware descriptor with the
following improvements.
- Validate the key-value length given in a vendor descriptor
against the length of the descriptor. The current code fails
to do this and might read more bytes than available. This can
lead to out-of-bounds reads of the allocated buffer.
- Read raw data with helpers for unaligned data. This allows
the code to run on platforms that do now support unaligned memory
access by default.
- Validate the pixel limit against a default value. The default
comes from real-world devices. If the reported number of pixels
is significantly above the limit, it is likely invalid.
- Drop the obsolete print macros. There is still a warning about
invalid firmware descriptors. The rest of the output is bogus.

There need to be least 5 bytes in the vendor descriptor. Return
an error otherwise. Also change the branching to early-out on
the error. Adjust indention of the rest of the parser function.
The original length test expected more than 5 bytes in the vendor

bytes and is still valid, change the test to accept this case as

Block validity checks need to be skipped in case they are called
for journal blocks since they are part of system's protected
zone.
Currently, this is done by checking inode->ino against
sbi->s_es->s_journal_inum, which is a direct read from the ext4 sb
buffer head. If someone modifies this underneath us then the
s_journal_inum field might get corrupted. To prevent against this,
change the check to directly compare the inode with journal->j_inode.
**Slight change in behavior**: During journal init path,
check_block_validity etc might be called for journal inode when
sbi->s_journal is not set yet. In this case we now proceed with
ext4_inode_block_valid() instead of returning early. Since systems zones
have not been set yet, it is okay to proceed so we can perform basic
checks on the blocks.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Hide get_vm_area() from MMUless builds
The function get_vm_area() is not defined when CONFIG_MMU is not
defined. Hide that function within #ifdef CONFIG_MMU.
- Fix output of synthetic events when they have dynamic strings
The print fmt of the synthetic event's format file use to have "%.*s"
for dynamic size strings even though the user space exported
arguments had only __get_str() macro that provided just a nul
terminated string. This was fixed so that user space could parse this
properly.
But the reason that it had "%.*s" was because internally it provided
the maximum size of the string as one of the arguments. The fix that
replaced "%.*s" with "%s" caused the trace output (when the kernel
reads the event) to write "(efault)" as it would now read the length
of the string as "%s".
As the string provided is always nul terminated, there's no reason
for the internal code to use "%.*s" anyway. Just remove the length
argument to match the "%s" that is now in the format.
- Fix the ftrace subops hash logic of the manager ops hash
The function_graph uses the ftrace subops code. The subops code is a
way to have a single ftrace_ops registered with ftrace to determine
what functions will call the ftrace_ops callback. More than one user
of function graph can register a ftrace_ops with it. The function
graph infrastructure will then add this ftrace_ops as a subops with
the main ftrace_ops it registers with ftrace. This is because the
functions will always call the function graph callback which in turn
calls the subops ftrace_ops callbacks.
The main ftrace_ops must add a callback to all the functions that the
subops want a callback from. When a subops is registered, it will
update the main ftrace_ops hash to include the functions it wants.
This is the logic that was broken.
The ftrace_ops hash has a "filter_hash" and a "notrace_hash" where
all the functions in the filter_hash but not in the notrace_hash are
attached by ftrace. The original logic would have the main ftrace_ops
filter_hash be a union of all the subops filter_hashes and the main
notrace_hash would be a intersect of all the subops filter hashes.
But this was incorrect because the notrace hash depends on the
filter_hash it is associated to and not the union of all
filter_hashes.
Instead, when a subops is added, just include all the functions of
the subops hash that are in its filter_hash but not in its
notrace_hash. The main subops hash should not use its notrace hash,
unless all of its subops hashes have an empty filter_hash (which
means to attach to all functions), and then, and only then, the main
ftrace_ops notrace hash can be the intersect of all the subops
hashes.
This not only fixes the bug, but also simplifies the code.
- Add a selftest to better test the subops filtering
Add a selftest that would catch the bug fixed by the above change.
- Fix extra newline printed in function tracing with retval
The function parameter code changed the output logic slightly and
called print_graph_retval() and also printed a newline. The
print_graph_retval() also prints a newline which caused blank lines
to be printed in the function graph tracer when retval was added.
This caused one of the selftests to fail if retvals were enabled.
Instead remove the new line output from print_graph_retval() and have
the callers always print the new line so that it doesn't have to do
special logic if it calls print_graph_retval() or not.
- Fix out-of-bound memory access in the runtime verifier
When rv_is_container_monitor() is called on the last entry on the
link list it references the next entry, which is the list head and
causes an out-of-bound memory access.

The retval and retaddr options for function_graph tracer will add a
comment at the end of a function for both leaf and non leaf functions that
looks like:
__wake_up_common(); /* ret=0x1 */
} /* pick_next_task_fair ret=0x0 */
The function print_graph_retval() adds a newline after the "*/". But if
that's not called, the caller function needs to make sure there's a
newline added.
This is confusing and when the function parameters code was added, it
added a newline even when calling print_graph_retval() as the fact that
the print_graph_retval() function prints a newline isn't obvious.
This caused an extra newline to be printed and that made it fail the
selftests when the retval option was set, as the selftests were not
expecting blank lines being injected into the trace.
Instead of having print_graph_retval() print a newline, just have the
caller always print the newline regardless if it calls print_graph_retval()
or not. This not only fixes this bug, but it also simplifies the code.

ftrace_ops filtering was incorrect. Add a new test to better test the

This test creates two instances, where it will add various filters to both

that the filters are behaving correctly.

The function graph infrastructure uses ftrace to hook to functions. It has
a single ftrace_ops to manage all the users of function graph. Each
individual user (tracing, bpf, fprobes, etc) has its own ftrace_ops to
track the functions it will have its callback called from. These
ftrace_ops are "subops" to the main ftrace_ops of the function graph
infrastructure.
Each ftrace_ops has a filter_hash and a notrace_hash that is defined as:
Only trace functions that are in the filter_hash but not in the
notrace_hash.
If the filter_hash is empty, it means to trace all functions.
If the notrace_hash is empty, it means do not disable any function.
The function graph main ftrace_ops needs to be a superset containing all
the functions to be traced by all the subops it has. The algorithm to
perform this merge was incorrect.
When the first subops was added to the main ops, it simply made the main
ops a copy of the subops (same filter_hash and notrace_hash).
When a second ops was added, it joined the new subops filter_hash with the
main ops filter_hash as a union of the two sets. The intersect between the
new subops notrace_hash and the main ops notrace_hash was created as the
new notrace_hash of the main ops.
The issue here is that it would then start tracing functions than no
subops were tracing. For example if you had two subops that had:
subops 1:
filter_hash = '*sched*' # trace all functions with "sched" in it
notrace_hash = '*time*' # except do not trace functions with "time"
subops 2:
filter_hash = '*lock*' # trace all functions with "lock" in it
notrace_hash = '*clock*' # except do not trace functions with "clock"
The intersect of '*time*' functions with '*clock*' functions could be the
empty set. That means the main ops will be tracing all functions with
'*time*' and all "*clock*" in it!
Instead, modify the algorithm to be a bit simpler and correct.
First, when adding a new subops, even if it's the first one, do not add
the notrace_hash if the filter_hash is not empty. Instead, just add the
functions that are in the filter_hash of the subops but not in the
notrace_hash of the subops into the main ops filter_hash. There's no
reason to add anything to the main ops notrace_hash.
The notrace_hash of the main ops should only be non empty iff all subops
filter_hashes are empty (meaning to trace all functions) and all subops
notrace_hashes include the same functions.
That is, the main ops notrace_hash is empty if any subops filter_hash is
non empty.
The main ops notrace_hash only has content in it if all subops
filter_hashes are empty, and the content are only functions that intersect
all the subops notrace_hashes. If any subops notrace_hash is empty, then
so is the main ops notrace_hash.

quirk_huawei_pcie_sva() sets properties needed by arm_smmu_probe_device(),
but bcb81ac6ae3c ("iommu: Get DT/ACPI parsing into the proper probe path")
changed the iommu_probe_device() flow so arm_smmu_probe_device() is now

pci_scan_single_device() in the generic enumeration path and
pci_bus_add_device() is called later, after all host bridges have been
enumerated.

Convert the raw spinlock used by BPF ringbuf to rqspinlock. Currently,
we have an open syzbot report of a potential deadlock. In addition, the
ringbuf can fail to reserve spuriously under contention from NMI
context.
It is potentially attractive to enable unconstrained usage (incl. NMIs)
while ensuring no deadlocks manifest at runtime, perform the conversion
to rqspinlock to achieve this.
This change was benchmarked for BPF ringbuf's multi-producer contention
case on an Intel Sapphire Rapids server, with hyperthreading disabled
and performance governor turned on. 5 warm up runs were done for each
case before obtaining the results.

Pull more block fixes from Jens Axboe:
"Apparently my internal clock was off, or perhaps it was just wishful
thinking, but I sent out block fixes yesterday as my brain assumed it
was Friday. Subsequently, that missed the NVMe fixes that should go
into this weeks release as well. Hence, here's a followup with those,
and another simple fix.
- NVMe pull request via Christoph:
- nvmet fc/fcloop refcounting fixes (Daniel Wagner)
- fix missed namespace/ANA scans (Hannes Reinecke)
- fix a use after free in the new TCP netns support (Kuniyuki
Iwashima)
- fix a NULL instead of false review in multipath (Uday Shankar)
- Use strscpy() for null_blk disk name copy"
* tag 'block-6.15-20250411' of git://git.kernel.dk/linux:
null_blk: Use strscpy() instead of strscpy_pad() in null_add_dev()
nvmet-fc: put ref when assoc->del_work is already scheduled
nvmet-fc: take tgtport reference only once
nvmet-fc: update tgtport ref per assoc
nvmet-fc: inline nvmet_fc_free_hostport
nvmet-fc: inline nvmet_fc_delete_assoc
nvmet-fcloop: add ref counting to lport
nvmet-fcloop: replace kref with refcount
