The subtract in this condition is reversed. The ->length is the length of the buffer. The ->bytesused is how many bytes we have copied thus far. When the condition is reversed that means the result of the subtraction is always negative but since it's unsigned then the result is a very high positive value. That means the overflow check is never true. Additionally, the ->bytesused doesn't actually work for this purpose because we're not writing to "buf->mem + buf->bytesused". Instead, the math to calculate the destination where we are writing is a bit involved. You calculate the number of full lines already written, multiply by two, skip a line if necessary so that we start on an odd numbered line, and add the offset into the line. To fix this buffer overflow, just take the actual destination where we are writing, if the offset is already out of bounds print an error and return. Otherwise, write up to buf->length bytes.

The JPEG decoder/encoder present in iMX8QXP and iMX8QM SoCs need the PER and IPG clocks to be functional, so add the clock entries.

Ensure that drivers set max_num_buffers to a value >= 32. For now there is no reason for drivers to request a lower limit and doing so might potentially cause userspace issues. Note that the old check of > MAX_BUFFER_INDEX was pointless since q->max_num_buffers was already limited to MAX_BUFFER_INDEX or less. Also add a sanity check in __vb2_init_fileio(), returning -ENOSPC if a driver returns more than 32 buffers from VIDIOC_REQBUFS with count = q->min_reqbufs_allocation. The vb2_fileio_data struct only supports up to 32 buffers, so we need a check there. Signed-off-by: -

If the CEC device is unregistered, then an attempt to open the device node should result in an -ENODEV error instead of -ENXIO. Document this as well in cec-func-open.rst. This is consistent with the error code returned by other file operations such as ioctl. Signed-off-by: -
Hans Verkuil authored
After the new V4L2 device node was registered, some additional initialization was done before the device node was marked as 'registered'. During the time between creating the device node and marking it as 'registered' it was possible to open the device node, which would return -ENODEV since the 'registered' flag was not yet set. Hold the videodev_lock mutex from just before the device node is registered until the 'registered' flag is set. Since v4l2_open will take the same lock, it will wait until this registration process is finished. This resolves this race condition. Signed-off-by:

On some ACPI platforms, such as Chromebooks the ACPI methods to change the power-state (_PS0 and _PS3) fully take care of powering on/off the sensor. On other ACPI platforms, such as e.g. various HP models with IPU6 + hi556 sensor, the sensor driver must control the avdd regulator itself. Add support for having the driver control the sensor's avdd regulator. Note this relies on the regulator-core providing a dummy regulator (which it does by default) on platforms where Linux is not aware of the avdd regulator. Signed-off-by:

There is no reason to send OV2680_END_MARGIN extra columns on top of the mode width and the same for sending extra lines over the mode height.

Since commit 63b0cd30 ("media: ov2680: Add bus-cfg / endpoint property verification") the ov2680 driver no longer probes when the 'data-lanes' property is absent.

The sensor gain (both analog and digital) are controlled by a single gain value where: - 0dB to 30dB correspond to analog gain - 30.3dB to 72dB correspond to digital gain (with 0.3dB step) Hence, limit the analogue gain value to 100. For digital gain, support can be added later if needed. Signed-off-by:

The imx335 reports a recommended pixel area of - 2592x1944. The driver supported mode however limits it to height=1940. Fix the height discrepency by correctly the value of height (with updates to vblank and mode registers).

When the source device is operating above 1.5 Gbps per lane, it needs to send the Skew Calibration Sequence before sending any HS data. If the DPHY is initialized after the source stream is started, then it might miss the sequence and not be able to receive data properly.

First the media device node was created, and if successful it was marked as 'registered'.

Logitech Rally Bar devices, despite behaving as UVC cameras, have a different power management system that the other cameras from Logitech. USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired USB disconnects in the Rally Bar that make them completely unusable. There is an open discussion about if we should fix this in the core or add a quirk in the UVC driver. In order to enable this hardware, let's land this patch first, and we can revert it later if there is a different conclusion.

The Samsung CSIS MIPI receiver provides a start-of-frame interrupt and a framecount register. As the CSI receiver is the hardware unit that lies closest to the sensor, the frame counter is the best we can get on these devices. In case of the ISI available on the i.MX8 M Plus it is also the only native start-of-frame signal available. This patch exposes the sof interrupt and the framecount as V4L2_EVENT_FRAME_SYNC event on the subdevice. It was tested on a Debix-Som-A with a 6.8-rc4 kernel. Reviewed-by:
