The 'disconnect' error injection functionality suffered from bit rot. New device nodes were added without updating vivid_user_gen_s_ctrl(), so that function had to be updated for the new device nodes. Also, vivid didn't check if specific device nodes were actually ever created, so the vivid_is_last_user() would fail on that (it would return true instead of false in that case). Finally, selecting Disconnect, then unbind the vivid driver would fail since the remove() would think that the device nodes were already unregistered. Keep track of whether disconnect was pressed and re-register the device nodes in remove() before doing the real unregister. [hverkuil: unsigned uses -> unsigned int uses] Signed-off-by:

The VNCSI_IFMD register controls the data expansion mode and the channel routing between the CSI-2 receivers and VIN instances. According to the chip manual revision 2.20 not all fields are available for all the SoCs: - V3M, V3H and E3 do not support the DES1 field has they do not feature a CSI20 receiver. - D3 only supports parallel input, and the whole register shall always be written as 0. Inspect the per-SoC channel routing table where the available CSI-2 instances are reported and configure VNCSI_IFMD accordingly. This patch supports this BSP change commit: https://github.com/renesas-rcar/linux-bsp/commit/f54697394457 ("media: rcar-vin: Fix VnCSI_IFMD register access for r8a77990") [hverkuil: replace BSP commit ID with BSP URL] Reviewed-by:

The GE2D is a 2D accelerator with various features like configurable blitter with alpha blending, frame rotation, scaling, format conversion and colorspace conversion. The driver implements a Memory2Memory VB2 V4L2 streaming device permitting: - 0, 90, 180, 270deg rotation - horizontal/vertical flipping - source cropping - destination compositing - 32bit/24bit/16bit format conversion This adds the support for the GE2D version found in the AXG SoCs Family.

Commit 31d9b9ef8564 ("media: cedrus: Register all codecs as capability") makes separate capability flags for each codec. However, VP8 codec was merged at the same time as mentioned patch, so there is no capability flag for it. This patch adds capability flag for VP8 and enables it for all variants except for V3s.

The gspca driver leaks memory when a probe fails. gspca_dev_probe2() calls v4l2_device_register(), which takes a reference to the underlying device node (in this case, a USB interface). But the failure pathway neglects to call v4l2_device_unregister(), the routine responsible for dropping this reference. Consequently the memory for the USB interface and its device never gets released. This patch adds the missing function call.

Document the naming scheme for the existing packed YUV 4:4:4 formats, as previously done for the RGB formats. Signed-off-by:
-
Laurent Pinchart authored
The 4:4:4 packed YUV formats are documented with a bit-level representation, which creates a wide table. Switch to a byte-oriented representation to make it more compact. This prepares for the addition of formats with more than 8 bits per component, that would make the table way too wide. Signed-off-by:

Laurent Pinchart authored
The padding bits are left blank, which look weird in the XYUV format, and, worse, may lead to the VUYX format to be understand as consuming 3 bytes per pixel. Add 'X' for padding bits as we do for RGB formats. Signed-off-by:

The pixfmt-packed-yuv.rst file documents packed YUV 4:4:4 formats, but is titled generically as "Packed YUV formats". 4:2:2 and 4:1:1 packed YUV formats are documented in separate files, which can be confusing. Group all packed YUV formats in pixfmt-packed-yuv.rst, which allows documenting the 4:2:2 formats in a more concise way. Signed-off-by:

Laurent Pinchart authored
The naming scheme for the RGB pixel formats has been developed organically, and isn't consistent between formats using less than 8 bits per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666 that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored in 3 or 4 bytes). For the latter category, the names use a components order convention that is the opposite of the first category, and the opposite of DRM pixel formats. This has led to lots of confusion in the past, and would really benefit from being explained more precisely. Do so, which also prepares for the addition of additional RGB pixels formats.

Hans Verkuil authored
The FWHT stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (fwht-ctrls.h). Now, the FWHT stateless controls is ready to be part of the stable uAPI. While not too late: - Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS. - Move the contents of fwht-ctrls.h to v4l2-controls.h. - Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h to v4l2-controls.h. - Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation. - Add p_fwht_params to struct v4l2_ext_control.
