[OpenIndiana-discuss] Solaris way of User space device driver (UIO)
Hi dear, I now writing cheap driver that useless and helps nobody. Fighting, but no hopefully, Especially debugging. I think it is easy way to Postponement kernel debug. Is there any Solaris implementation like LINUX-UIO >https://www.slideshare.net/chrissimmonds/quick-and-easy-device-drivers-for-embedded-linux-using-uio Regards, Ken,IDE ___ openindiana-discuss mailing list openindiana-discuss@openindiana.org https://openindiana.org/mailman/listinfo/openindiana-discuss

Hi Dear, I want to write driver to use in ZFS environment. Could anybody told me The parity bits (RAIDZ,RAIDZ2) places. Does the FS'es has own its region or continuously? And when I get sources and build environment in my sandbox, I will start try from /dev/null, Someone told me it locates?

[OpenIndiana-discuss] how to write device drivers
Hi, I am application engineer, but I want to write device driver that run in user process. Character and Block device I want to write, But I do not know where am I start. chardev? very easy way , look /dev/null you lough, but I do not know where it place. and I do not know the magic number that how can I decide dev_no, more, the rule of /devices/. I order my new machine, the sandbox please tell me how to write drivers.
