Hi all, These mails contain RFC patches, which are almost bug report and some are just bug report, for atomisp to work (again). Tested on Microsoft Surface 3 (Windows) and Xiaomi Mi Pad 2 (Android model) with v5.15-rc5. Both are Cherry Trail (ISP2401) devices. I'm still not used to Linux patch sending flow. Sorry in advance if there is some weirdness :-) but I did my best. To try to take a picture, take a look at the series I sent earlier named ("various fixes for atomisp to make it work") The 1st patch is required to take a picture with atomsip (again): [BUG][RFC] media: atomisp: pci: assume run_mode is PREVIEW The 2nd patch is to avoid kernel warning message: [BUG][RFC] media: atomisp: pci: remove dummy_ptr NULL check to avoid duplicate active_bo The 3rd patch is to avoid kernel oops, which is almost required for using atomisp normally: [BUG][RFC] media: atomisp: pci: add NULL check for asd obtained from atomisp_video_pipe The 4th-5th mail is bug reports, no patches for these issues yet: [BUG] media: atomisp: `modprobe -r` not working well (dup video4linux, ATOMISP_SUBDEV_{0,1}) [BUG] media: atomisp: atomisp causes touchscreen to stop working on Microsoft Surface 3 I added further descriptions at the top of each RFC/BUG mails.
