Re: [PATCH 3/3] media: dvb_frontend: Add commands implementation for compat ioct

Hello Sorry if I say something completely wrong here, I was thinking to implement the same on my own As far as I understand from the patch, you have added two "compact" specific ioctl commands As far as I know, the compact_ioctl is called automatically when the userland is 32 bit and kernel is 64

Re: [bug report] media: dvb_frontend: cleanup ioctl handling logic

Hello Is anyone working on adding compact_ioctl? So far it is impossible to use linux-media from 32bit userland on 64bit kernels Bye 2017-11-30 10:58 GMT+01:00 Dan Carpenter : > Hello Mauro Carvalho Chehab, > > The patch d73dcf0cdb95: "media: dvb_frontend: cleanup ioctl

32bit userland cannot work with DVB drivers in 64bit kernel, design issue

Hi all I am investigating for Armbian, the feasability of running 32bit userland on single board computers based on arm64 SoC, where only 64 bit kernel is available, for reducing the memory footprint. I have discovered that there is a flaw in the DVB frontend ioctl (at least) that prevents to do
