Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base.
It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and
the base is:

Prepare v4.1.3-rt3

We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

To load this +firmware you need "pcbitctl" available on the standard isdn4k-utils +package or in the pcbit package available in: + +ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn + +Known Limitations: + +- The board reset procedure is at the moment incorrect and will only +allow you to load the firmware after a hard reset. + +- Only HDLC in B-channels is supported at the moment. There is no +current support for X.25 in B or D channels nor LAPD in B +channels. The main reason is that these two other protocol modes have, +to my knowledge, very little use. If you want to see them implemented +*do* send me a mail. + +- The driver often triggers errors in the board that I and the +manufacturer believe to be caused by bugs in the firmware. The current +version includes several procedures for error recovery that should +allow normal operation. Plans for the future include cooperation with +the manufacturer in order to solve this problem. + +Information/hints/help can be obtained in the linux isdn +mailing list (isdn4linux@listserv.isdn4linux.de) or directly from me. + +regards, + Pedro. + +<roque@di.fc.ul.pt> |
