Hi,
How can I enable VIDEOBUF2_VMALLOC? I try 'make menuconfig', but I don't know how can I configure to enable VIDEOBUF2_VMALLOC:
The videobuf2 supports 3 types of buffer: 1: VIDEOBUF2_DMA_CONTIG 2: VIDEOBUF2_DMA_SG 3: VIDEOBUF2_VMALLOC It all depends on your hardware (bridge driver) which supports this So if your bridge driver supports say VIDEOBUF2_VMALLOC then in your Kconfig for the bridge driver you need to add the following line select VIDEOBUF2_VMALLOC so this will be built along your driver. Hope this helps! Thanks, --Prabhakar Lad https://www.linkedin.com/in/prabhakarlad
Symbol: VIDEOBUF2_VMALLOC [=n] │ Type : tristate │ Defined at drivers/media/v4l2-core/Kconfig:75 │ Depends on: MEDIA_SUPPORT [=y] │ Selects: VIDEOBUF2_CORE [=y] && VIDEOBUF2_MEMOPS [=n] && DMA_SHARED_BUFFER [=y] │ Selected by: USB_VIDEO_CLASS [=n] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=n] && MEDIA_CAMERA_SUPPORT [=y] || USB_PWC [=n] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=n] && MEDIA_CAMERA_SUPPORT [=y] && VIDEO_V4L2 [=y] || VIDEO_STK1160 [=n] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=n] && MEDIA_ANALOG_TV_SUPPORT [=n] && VIDEO_DEV [=y] && I2C [=y] || VIDEO_EM28XX [=n] && USB [=y] && MEDIA_SUPPORT [=y] && MEDIA_USB_SUPPORT [=n] && (MEDIA_CAMERA_SUPPORT [=y]
