In the stateless decoder the reference buffer is null if the frame is an I-frame (flagged with FWHT_FL_I_FRAME). Make sure not to dereference it in that case. Signed-off-by:

Rename 'v4l2_fwht_default_fmt' to 'v4l2_fwht_find_nth_fmt' and add a function 'v4l2_fwht_validate_fmt' to check if a format info matches the parameters. This function will also be used to validate the stateless params when adding support for stateless codecs. Signed-off-by:

In the decoder, save the inner reference frame in the same format as the capture buffer. The decoder writes directly to the capture buffer and then the capture buffer is copied to the reference buffer. This will simplify the stateless decoder. Signed-off-by:

Add the field 'buf' to fwht_raw_frame to indicate the start of the raw frame buffer. This field will be used to copy the capture buffer to the reference buffer in the next patch. Signed-off-by:

The function 'v4l2_m2m_buf_copy_metadata' should be called even if decoding/encoding ends with status VB2_BUF_STATE_ERROR, so that the metadata is copied from the source buffer to the dest buffer. Signed-off-by:

v4l2_fwht_encode returns either an error code on failure or the size of the compressed frame on success. So change the var assigned to it from 'ret' to 'comp_sz_or_errcode' to clarify that. Signed-off-by:

The logic of g_selection was wrong: encoders support crop, decoders support compose, but the code allowed both. Signed-off-by:

The selection api should check only single buffer types because multiplanar types are converted to single in drivers/media/v4l2-core/v4l2-ioctl.c Signed-off-by:

If requests are used when they shouldn't, or not used when they should, then return EBADR (Invalid request descriptor) instead of EACCES. The reason for this change is that EACCES has more to do with permissions (not being the owner of the resource), but in this case the request file descriptor is just wrong for the current mode of the device. Update the documentation accordingly. Signed-off-by:

The cedrus stateless decoder requires the use of request, so indicate this by setting requires_requests to 1. Note that the cedrus driver never checked for this, and as far as I can tell would just crash if an attempt was made to queue a buffer without a request. Signed-off-by:
-
Hans Verkuil authored
Stateless codecs require the use of the Request API as opposed of it being optional. So add a bit to indicate this and let vb2 check for this. If an attempt is made to queue a buffer without an associated request, then the EBADR error is returned to userspace. Doing this check in the vb2 core simplifies drivers, since they don't have to check for this, they can just set this flag. Signed-off-by:

C-PHY has no clock lanes. Therefore the first data lane is 0 by default. Fixes: edc6d56c ("media: v4l: fwnode: Support parsing of CSI-2 C-PHY endpoints") Signed-off-by:
-
Sakari Ailus authored
The lack of defaults provided by the caller to v4l2_fwnode_endpoint_parse() signals the use of the default lane mapping. The default lane mapping must not be used however if the firmmare contains the lane mapping. Disable the default lane mapping in that case, and improve the debug messages telling of the use of the defaults. This was missed previously since the default mapping will only unsed in this case if the bus type is set, and no driver did both while still needing the lane mapping configuration.

Since commit 3d6a8fe2 ("media: ov7670: hook s_power onto v4l2 core"), the device is actually powered off while the video stream is stopped. So now set_format and s_frame_interval could be called while the device is powered off, but these callbacks try to change the register settings at this time. The frame format and framerate will be restored right after power-up, so we can just postpone applying these changes at these callbacks if the device is not powered up.

The imgu_rpm_dummy_cb() looks like an API misuse that is explained in the comment above it. Aside from that, it also causes a warning when power management support is disabled: drivers/staging/media/ipu3/ipu3.c:794:12: error: 'imgu_rpm_dummy_cb' defined but not used [-Werror=unused-function] The warning is at least easy to fix by marking the function as __maybe_unused.

When start_streaming was called both last_src_buf and last_dst_buf pointers were set to NULL, but this depends on whether the capture or output queue starts streaming. When decoding with resolution changes in between the capture queue has to restart streaming whenever a resolution change occurs. And that would reset last_src_buf as well, which causes a problem if the decoder was stopped by the application. Since last_src_buf is now NULL, the LAST flag is never set for the last capture buffer. Signed-off-by:

Some functions like enum_fmt use the buffer type as was passed from userspace, which might cause the switch to fall into the default case. Just drop the WARN_ON(1) to avoid kernel log pollution. Signed-off-by:

si2165_readreg8() may fail. Looking into si2165_readreg8(), we will find that "val_tmp" will be an uninitialized value when regmap_read() fails. "val_tmp" is then assigned to "val". So if si2165_readreg8() fails, "val" will be a random value. Further use will lead to undefined behaviors. The fix checks if si2165_readreg8() fails, and if so, returns its error code upstream.
