Add support for the vfe-340 PIX write engine, enabling frame capture through the PIX video device (e.g. msm_vfe0_pix). The PIX path requires a separate configuration flow from RDI, including cropping setup, line- based write engine configuration, and the correct packer format based on the input pixel format. In contrast to RDI, the PIX interface embeds a lightweight processing engine we can use for cropping, configuring custom stride/alignment, and, in the future, extracting frame statistics. The functionality has been validated on Arduino-Uno-Q with: media-ctl -d /dev/media0 --reset media-ctl -d /dev/media0 -l '"msm_csiphy0":1->"msm_csid0":0[1],"msm_csid0":4->"msm_vfe0_pix":0[1]' media-ctl -d /dev/media0 -V '"imx219 1-0010":0[fmt:SRGGB8_1X8/640x480 field:none]' media-ctl -d /dev/media0 -V '"msm_csiphy0":0[fmt:SRGGB8_1X8/640x480 field:none]' media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:SRGGB8_1X8/640x480 field:none]' media-ctl -d /dev/media0 -V '"msm_vfe0_pix":0[fmt:SRGGB8_1X8/640x480 field:none]' yavta -B capture-mplane --capture=3 -n 3 -f SRGGB8 -s 640x480 /dev/video3 Signed-off-by: Loic Poulain <loic.poulain@oss.qualcomm.com> [bod: Squash down fix for bpp unused in vfe_packer_format] Signed-off-by: Bryan O'Donoghue <bod@kernel.org> |
