a519e21e32 media: chips-media: wave5: Fix memory leak on codec_info allocation failure
In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is
allocated via kzalloc(). If the subsequent allocation for inst->codec_info
fails, the functions return -ENOMEM without freeing the previously
allocated instance, causing a memory leak.

Fix this by calling kfree() on the instance in this error path to ensure
it is properly released.

a176ac5e70 media: chips-media: wave5: Improve performance of decoder
The current decoding method  was to wait until each frame was
decoded after feeding a bitstream. As a result, performance was low
and Wave5 could not achieve max pixel processing rate.

Update driver to use an asynchronous approach for decoding and feeding a
bitstream in order to achieve full capabilities of the device.

WAVE5 supports command-queueing to maximize performance by pipelining
internal commands and by hiding wait cycle taken to receive a command
from Host processor.

Instead of waiting for each command to be executed before sending the
next command, Host processor just places all the commands in the
command-queue and goes on doing other things while the commands in the
queue are processed by VPU.

While Host processor handles its own tasks, it can receive VPU interrupt
request (IRQ).
In this case, host processor can simply exit interrupt service routine
(ISR) without accessing to host interface to read the result of the
command reported by VPU.
After host processor completed its tasks, host processor can read the
command result when host processor needs the reports and does
response processing.

To achieve this goal, the device_run() calls v4l2_m2m_job_finish
so that next command can be sent to VPU continuously, if there is
any result, then irq is triggered and gets decoded frames and returns
them to upper layer.
Theses processes work independently each other without waiting
a decoded frame.

e66ff2b08e media: chips-media: wave5: Fix Null reference while testing fluster
When multi instances are created/destroyed, many interrupts happens
and structures for decoder are removed.
"struct vpu_instance" this structure is shared for all flow in the decoder,
so if the structure is not protected by lock, Null dereference
could happens sometimes.
IRQ Handler was spilt to two phases and Lock was added as well.

b74cedac64 media: chips-media: wave5: Fix device cleanup order to prevent kernel panic
Move video device unregistration to the beginning of the remove function
to ensure all video operations are stopped before cleaning up the worker
thread and disabling PM runtime. This prevents hardware register access
after the device has been powered down.

In polling mode, the hrtimer periodically triggers
wave5_vpu_timer_callback() which queues work to the kthread worker.
The worker executes wave5_vpu_irq_work_fn() which reads hardware
registers via wave5_vdi_read_register().

The original cleanup order disabled PM runtime and powered down hardware
before unregistering video devices. When autosuspend triggers and powers
off the hardware, the video devices are still registered and the worker
thread can still be triggered by the hrtimer, causing it to attempt
reading registers from powered-off hardware. This results in a bus error
(synchronous external abort) and kernel panic.

This causes random kernel panics during encoding operations:

5a0c122e83 media: chips-media: wave5: Fix kthread worker destruction in polling mode
Fix the cleanup order in polling mode (irq < 0) to prevent kernel warnings
during module removal. Cancel the hrtimer before destroying the kthread
worker to ensure work queues are empty.

In polling mode, the driver uses hrtimer to periodically trigger
wave5_vpu_timer_callback() which queues work via kthread_queue_work().
The kthread_destroy_worker() function validates that both work queues
are empty with WARN_ON(!list_empty(&worker->work_list)) and
WARN_ON(!list_empty(&worker->delayed_work_list)).

The original code called kthread_destroy_worker() before hrtimer_cancel(),
creating a race condition where the timer could fire during worker
destruction and queue new work, triggering the WARN_ON.

This causes the following warning on every module unload in polling mode:

9cf4452e82 media: chips-media: wave5: Fix PM runtime usage count underflow
Replace pm_runtime_put_sync() with pm_runtime_dont_use_autosuspend() in
the remove path to properly pair with pm_runtime_use_autosuspend() from
probe. This allows pm_runtime_disable() to handle reference count cleanup
correctly regardless of current suspend state.

The driver calls pm_runtime_put_sync() unconditionally in remove, but the
device may already be suspended due to autosuspend configured in probe.
When autosuspend has already suspended the device, the usage count is 0,
and pm_runtime_put_sync() decrements it to -1.

This causes the following warning on module unload:

241e75fe6b media: imx-jpeg: Add support for descriptor allocation from SRAM
Add support for optional allocation of bitstream descriptors from SRAM
instead of DRAM. In case the encoder/decoder DT node contains 'sram'
property which points to 'mmio-sram', the driver will attempt to use
the SRAM instead of DRAM for descriptor allocation, which might improve
performance.

This also helps on i.MX95 rev.A with sporadic SLOTn_STATUS IMG_RD_ERR
bit 11 being triggered during JPEG encoding, which is caused by a bug
fixed on later SoC revisions. The bug occurs less often when using the
SRAM for descriptor storage, but is not entirely mitigated. The following
pipeline triggers the bug when descriptors get allocated from DRAM, the
pipeline often hangs after a few seconds and the encoder driver indicates
"timeout, cancel it":

using = { } to initialize a structure or array is the preferred way

Converts memset() to = { }, thereby:
- Eliminating the risk of sizeof() mismatches.
- Simplifying the code.

ab0308aee3 x86,fs/resctrl: Handle events that can be read from any CPU
resctrl assumes that monitor events can only be read from a CPU in the
cpumask_t set of each domain.  This is true for x86 events accessed with an
MSR interface, but may not be true for other access methods such as MMIO.

Introduce and use flag mon_evt::any_cpu, settable by architecture, that
indicates there are no restrictions on which CPU can read that event.  This
flag is not supported by the L3 event reading that requires to be run on a CPU
that belongs to the L3 domain of the event being read.

dd110880e8 fs/resctrl: Make event details accessible to functions when reading events
Reading monitoring event data from MMIO requires more context than the event id
to be able to read the correct memory location. struct mon_evt is the appropriate
place for this event specific context.

Prepare for addition of extra fields to struct mon_evt by changing the calling
conventions to pass a pointer to the mon_evt structure instead of just the
event id.

f3d22e5f63 arm64: dts: renesas: r9a09g056: Add TSU nodes
The Renesas RZ/V2N SoC includes a Thermal Sensor Unit (TSU) block designed
to measure the junction temperature. The device provides real-time
temperature measurements for thermal management, utilizing two dedicated
channels for temperature sensing:
- TSU0, which is located near the DRP-AI block
- TSU1, which is located near the CPU and DRP-AI block

Since TSU1 is physically closer the CPU and the highest temperature
spot, it is used for CPU throttling through a passive trip and cooling
map. TSU0 is configured only with a critical trip.

Add TSU nodes along with thermal zones and keep them enabled in the SoC
DTSI.
