I hope this is a good place. pinchartl: <u>fdk17</u>: feel free to ask :-) fdk17: Okay. Thanks. So in the V4L2 driver that I'm writing I need to capture to contiguous physical memory. This in is kernel v4.19.y. But it doesn't appear that DMA_ATTR_FORCE_CONTIGUOUS is being used. Does using videobuf2-dma-contig mean that continguous physical memory is being used or that in the userland the memory will look contiguous? ezequielg: <u>hverkuil</u>: you mentioned running smatch on the rkvdec review and i'm really curious how you are using smatch. <br> if anyone else has tips on smatch or other static analyzers, i'd love to hear that. ***: indy has quit IRC (Ping timeout: 244 seconds) <br> uajain has quit IRC (*.net *.split) <br> mjasny has quit IRC (*.net *.split) <br> sailus has quit IRC (*.net *.split) <br> Muzer has quit IRC (*.net *.split) <br> mripard has quit IRC (*.net *.split)
