without using any of the atomisp_gmin power-management code.

Note eventually these calls should be replaced by the standard

media: atomisp: Add v4l2_get_acpi_sensor_info() helper

ACPI nodes describing sensors on atomisp devices implement a
"79234640-9e10-4fea-a5c1-b5aa8b19756f" Device Specific Method (DSM)
to get info about the GPIOs.

Using this method is necessary to figure out which ACPI GPIO resource
is "reset" and which one is "powerdown" and this is also necessary to
figure out the correct polarity of the pins.

One example where this is necessary is the GC0310 sensor. The current
GC0310 code hardcodes reset as being active-low and power-down as being
active-high. This works on a number of devices such as the mpman
converter 9. But it is wrong for the Chuwi Vi8 CWI501 where the powerdown
pin is active-low.

Rather then adding DMI quirks for this, add a helper for this,
which can be shared between sensor-drivers. This new helper optionally
also returns a string identifying the exact sensor-module used, which
might be useful if any module specific behvior is necessary in the sensor
driver.

This uses the DSM directly on the sensor device's ACPI node. This is
different from later Intel hardware (IPU3 / IPU6) which has a separate
INT3472 node (with its own driver) with this info.

Since there is no separate ACPI node to which we can bind to register GPIO
lookups, this unfortunately means that all sensor drivers which may be used
on BYT or CHT hw need to call this new helper.

Note for now this function is being added to atomisp_gmin_platform.c,
but once things are ready to move atomisp over to using generic sensor
drivers this will need to become a generic v4l2 sensor helper. but this
will require upstream discussion first.

From 26fc9fe5030b63bc9dcf0b5f32981948911ca272 Mon Sep 17 00:00:00 2001

Date: Fri, 7 Jul 2017 14:23:53 -0700
Subject: [PATCH] linux-yocto: Remove remaining instance of call to
 trace_printk

It's not sufficient to leave trace_printk() out of "normal call chains" since
the way trace infrastructure works is that it will allocate the trace_printk
buffers if the symbol is there (by using a separate section for the function
and checking if __start_* and __stop_* symbols are different.

Therefore, even if the default value for the param tells the module to use
printk(), just the fact that it can be changed to trace_printk() means the
initialization code will be called.

The trace_printk() was replaced by pr_info() on commit 3d81099c75a6
("media: atomisp: Replace trace_printk by pr_info") for the upstreamed
atomisp, too. However, as the aforementioned commit message says, there
is still a remaining instance. This causes the "trace_printk() being
used" kernel warning message to still appear on the first driver load.

Based on the aforementioned patch, this patch removes the call to
ftrace_vprintk(). This removes that kernel warning.

In addition to this, this patch also removes the following now unused
things:

    - now empty atomisp_css2_dbg_ftrace_print()
    - trace_printk option from dbg_func kernel parameter

use a single stream multiplexed by pipewire.

The still-capture case is extra special only starting the preview
stream and then relying on a custom ATOMISP_IOC_S_CONT_CAPTURE_CONFIG

18 months agomedia: v4l2-subdev: Add new ioctl for client capabilities
Tomi Valkeinen [Thu, 23 Mar 2023 13:58:35 +0000 (13:58 +0000)]
media: v4l2-subdev: Add new ioctl for client capabilities

Add new ioctls to set and get subdev client capabilities. Client in this
context means the userspace application which opens the subdev device
node. The client capabilities are stored in the file handle of the
opened subdev device node, and the client must set the capabilities for
each opened subdev.

For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which
indicates that the client is streams-aware.

The reason for needing such a flag is as follows:

Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain
reserved fields (usually a single array field). These reserved fields
can be used to extend the ioctl. The userspace is required to zero the
reserved fields.

We recently added a new 'stream' field to many of these structs, and the
space for the field was taken from these reserved arrays. The assumption
was that these new 'stream' fields are always initialized to zero if the
userspace does not use them. This was a mistake, as, as mentioned above,
the userspace is required to zero the _reserved_ fields. In other words,
there is no requirement to zero this new stream field, and if the
userspace doesn't use the field (which is the case for all userspace
applications at the moment), the field may contain random data.

This shows that the way the reserved fields are defined in v4l2 is, in
my opinion, somewhat broken, but there is nothing to do about that.

To fix this issue we need a way for the userspace to tell the kernel
that the userspace has indeed set the 'stream' field, and it's fine for
the kernel to access it. This is achieved with the new ioctl, which the
userspace should usually use right after opening the subdev device node.

media: Zero-initialize all structures passed to subdev pad operations

Several drivers call subdev pad operations, passing structures that are
not fully zeroed. While the drivers initialize the fields they care
about explicitly, this results in reserved fields having uninitialized
values. Future kernel API changes that make use of those fields thus
risk breaking proper driver operation in ways that could be hard to
detect.

To avoid this, make the code more robust by zero-initializing all the
structures passed to subdev pad operation. Maintain a consistent coding
style by preferring designated initializers (which zero-initialize all
the fields that are not specified) over memset() where possible, and
make variable declarations local to inner scopes where applicable. One
notable exception to this rule is in the ipu3 driver, where a memset()
is needed as the structure is not a local variable but a function
parameter provided by the caller.

Not all fields of those structures can be initialized when declaring the
variables, as the values for those fields are computed later in the
code. Initialize the 'which' field in all cases, and other fields when
the variable declaration is so close to the v4l2_subdev_call() call that
it keeps all the context easily visible when reading the code, to avoid
hindering readability.
