8603922f08 media: staging/ipu7: Call synchronous RPM suspend in probe failure
[ Upstream commit 1433e6ccc2 ]

If firmware authentication failed during driver probe, driver call an
asynchronous API to suspend the psys device but the bus device will be
removed soon, thus runtime PM of bus device will be disabled soon, that
will cancel the suspend request, so use synchronous suspend to make
sure the runtime suspend before disabling its RPM.

IPU7 hardware has constraints that the PSYS device must be powered off
before ISYS, otherwise it will cause machine check error.

9a8c3cd8a0 media: staging/ipu7: Ignore interrupts when device is suspended
[ Upstream commit 9ad65684b9 ]

IPU7 devices have shared interrupts with others. In some case when IPU7
device is suspended, driver get unexpected interrupt and invalid irq
status 0xffffffff from ISR_STATUS and PB LOCAL_STATUS registers as
interrupt is triggered from other device on shared irq line.

In order to avoid this issue use pm_runtime_get_if_active() to check if
IPU7 device is resumed, ignore the invalid irq status and use
synchronize_irq() in suspend.

[ Upstream commit 401aec35ac ]

We have experienced seen multiple I2C errors while doing stress test on

Inspecting the powerup sequence we found that it does not match the
documentation at:

"""
(2) DW9714A requires waiting time of 12ms after power on. During this
waiting time, the offset calibration of internal amplifier is

fade67c888 media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()
[ Upstream commit d965919af5 ]

vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop
bound and passes the index to vfe_isr_reg_update(). However,
vfe->line[] array is defined with VFE_LINE_NUM_MAX(4):

    struct vfe_line line[VFE_LINE_NUM_MAX];

When index is 4, 5, 6, the access to vfe->line[line_id] exceeds
the array bounds and resulting in out-of-bounds memory access.

Fix this by using separate loops for output lines and write masters.

[ Upstream commit 109e0feaca ]

A analogue maximum gain of 0xffff / 65525 seems unlikely and testing
indeed shows that the gain control wraps-around at 16383, so set the
maximum gain to 0x3fff / 16383.

The minimum gain of 0x100 is correct. Setting bits 8-11 to 0x0 results
in the same gain values as setting these bits to 0x1, with bits 0-7
still increasing the gain when going from 0x000 - 0x0ff in the exact
same range as when going from 0x100 - 0x1ff.

8df26a7649 media: i2c: ov01a10: Fix the horizontal flip control
[ Upstream commit ada20c3db0 ]

During sensor calibration I noticed that with the hflip control set
to false/disabled the image was mirrored.

So it seems that the horizontal flip control is inverted and needs to
be set to 1 to not flip (just like the similar problem recently fixed
on the ov08x40 sensor).

Invert the hflip control to fix the sensor mirroring by default.

As the comment above the newly added OV01A10_MEDIA_BUS_FMT define explains
the control being inverted also means that the native Bayer-order of
the sensor actually is GBRG not BGGR, but so as to not break userspace
the Bayer-order is kept at BGGR.

1d8558a232 media: radio-keene: fix memory leak in error path
[ Upstream commit b8bf939d77 ]

Fix a memory leak in usb_keene_probe(). The v4l2 control handler is
initialized and controls are added, but if v4l2_device_register() or
video_register_device() fails afterward, the handler was never freed,
leaking memory.

Add v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure
the control handler is properly freed for all error paths after it is
initialized.

[ Upstream commit 5633ec763a ]

The min_queued_buffers field controls when start_streaming() is called
by the vb2 core (it delays the callback until at least N buffers are
queued). Setting it to 1 affects the timing of start_streaming(), which
breaks the seek flow in decoder scenarios and causes test failures.

The current driver implementation does not rely on this minimum buffer
requirement and handles streaming start correctly with the default
value of 0, so remove these assignments.

a2ac388aa8 arm64: dts: apple: t8112-j473: Keep the HDMI port powered on
[ Upstream commit 3e4e729325 ]

Add the display controller and DPTX phy power-domains to the framebuffer
node to keep the framebuffer and display out working after device probing
finished.
The OS has more control about the display pipeline used for the HDMI
output on M2 based devices. The HDMI output is driven by an integrated
DisplayPort to HDMI converter (Parade PS190). The DPTX phy is now
controlled by the OS and no longer by firmware running on the display
co-processor. This allows using the second display controller on the
second USB type-c port or tunneling 2 DisplayPort connections over
USB4/Thunderbolt.
The m1n1 bootloader uses the second display controller to drive the HDMI
output. Adjust for this difference compared to the notebooks as well.

e3e6e2e4d6 arm64: Disable branch profiling for all arm64 code
[ Upstream commit f22c81bebf ]

The arm64 kernel doesn't boot with annotated branches
(PROFILE_ANNOTATED_BRANCHES) enabled and CONFIG_DEBUG_VIRTUAL together.

Bisecting it, I found that disabling branch profiling in arch/arm64/mm
solved the problem. Narrowing down a bit further, I found that
physaddr.c is the file that needs to have branch profiling disabled to
get the machine to boot.

I suspect that it might invoke some ftrace helper very early in the boot
process and ftrace is still not enabled(!?).

Rather than playing whack-a-mole with individual files, disable branch
profiling for the entire arch/arm64 tree, similar to what x86 already
does in arch/x86/Kbuild.

Drop the WARN in svm_set_nested_state() on nested_svm_load_cr3() failing

Simply delete the WARN instead of trying to prevent userspace from shoving
"illegal" state into CR3.  For better or worse, KVM's ABI allows userspace
to set CPUID after SREGS, and vice versa, and KVM is very permissive when
it comes to guest CPUID.  I.e. attempting to enforce the virtual CPU model
when setting CPUID could break userspace.  Given that the WARN doesn't
provide any meaningful protection for KVM or benefit for userspace, simply
drop it even though the odds of breaking userspace are minuscule.

Opportunistically delete a spurious newline.

e28f451025 powerpc/pseries: Fix MSI-X allocation failure when quota is exceeded
[ Upstream commit c0215e2d72 ]

Nilay reported that since commit daaa574aba ("powerpc/pseries/msi: Switch
to msi_create_parent_irq_domain()"), the NVMe driver cannot enable MSI-X
when the device's MSI-X table size is larger than the firmware's MSI quota
for the device.

This is because the commit changes how rtas_prepare_msi_irqs() is called:

  - Before, it is called when interrupts are allocated at the global
    interrupt domain with nvec_in being the number of allocated interrupts.
    rtas_prepare_msi_irqs() can return a positive number and the allocation
    will be retried.

  - Now, it is called at the creation of per-device interrupt domain with
    nvec_in being the number of interrupts that the device supports. If
    rtas_prepare_msi_irqs() returns positive, domain creation just fails.

For Nilay's NVMe driver case, rtas_prepare_msi_irqs() returns a positive
number (the quota). This causes per-device interrupt domain creation to
fail and thus the NVMe driver cannot enable MSI-X.

Rework to make this scenario works again:

  - pseries_msi_ops_prepare() only prepares as many interrupts as the quota
    permit.

  - pseries_irq_domain_alloc() fails if the device's quota is exceeded.

Now, if the quota is exceeded, pseries_msi_ops_prepare() will only prepare
as allowed by the quota. If device drivers attempt to allocate more
interrupts than the quota permits, pseries_irq_domain_alloc() will return
an error code and msi_handle_pci_fail() will allow device drivers a retry.

b965b990c1 arm64: dts: qcom: x1e80100: Add missing TCSR ref clock to the DP PHYs
[ Upstream commit 0907cab01f ]

The DP PHYs on X1E80100 need the ref clock which is provided by the
TCSR CC.

The current X Elite devices supported upstream work fine without this
clock, because the boot firmware leaves this clock enabled. But we should
not rely on that. Also, even though this change breaks the ABI, it is
needed in order to make the driver disables this clock along with the
other ones, for a proper bring-down of the entire PHY.

So lets attach it to each of the DP PHYs in order to do that.

adae1932f0 media: verisilicon: AV1: Fix tx mode bit setting
[ Upstream commit cb3f945c01 ]

AV1 specification describes 3 possibles tx modes: 4x4 only, largest and
select. The hardware allows 5 possibles tx modes: 4x4 only, 8x8, 16x16,
32x32 and select. Since the both aren't exactly matching we need to add
a mapping function to set the correct mode on hardware.

ea316b784f media: chips-media: wave5: Fix Null reference while testing fluster
[ Upstream commit e66ff2b08e ]

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.

526816f2e3 media: chips-media: wave5: Fix device cleanup order to prevent kernel panic
[ Upstream commit b74cedac64 ]

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:
