Well the nightmare userspace switch from ttyS to ttyO few years ago is something we want to avoid.. I think the best solution would be to make serial-omap.c transparently provide support for ttyO using the new 8250 code so both ttyS and ttyO devices would just work. Otherwise it will be years of "my serial port stopped working" questions again.Thata a udev problem not a kernel one surely.People also use serial console to observe the early kernel boot before the userspace is started.
right, we need a way to tell the kernel that ttyO%d and ttyS%d are the exact same device so that console=ttyO0 and console=ttyS0 mean the same thing. That maintains backwards compatibility and lets people move on -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
