    that is not hybrid driver, that is nvidia extension

In my perfect world, I'll get to run my 2xHD 7970 GHz. Ed. cards on Linux instead of Windows using the hybrid driver. Pretty please? =)
      I think we understand the desire well enough that more voices of support isn't going to make any real difference (I've never believed they make much difference at the best of times personally). Not sure if we'll be able to put enough time into it to do it all ourselves but I expect that between us and community it should be able to happen. We're trying to formalize some of that now.

      Did that HW combination work with different drivers ? Wondering if this is a function of enabling DAL (which AFAIK is on in the hybrid driver but not in upstream).

            uh, as a R9 270X owner, could you clarify this a bit? Worst case scenario, AMDGPU support will

            a) not happen
            b) take a long time (maybe even only in 2017)

              Worst case it will take a long time. It doesn't need anything from us, people are just hoping that we will do all the work

              I'm thinking the initial support will be some combination of us helping with initial code and debugging into the closed components if needed, community devs/users help with testing & bug fixing so we don't have to go find a big pile of QA and dev resources we don't have today. Something like that.

              Ideally in a usable state before the current round of 14.04.x HWE distros that Catalyst supports hit EOL in August, but that's tight.

              We are trying to put a more detailed plan together now - I was hoping to finish this week but the hybrid driver launch interfered with that a bit. That's why I've been saying "ask again in a week".

                so, the current driver could already support GC 1.0 hardware but it's disabled because untested?

                Sorry that I'm bugging your about that, and I really appreciate it that you're answering stuff here on a Saturday!

                  1. Even with smaller test coverage, AMD will still fix bugs found by GCN 1.1 hardware owners - is that correct?
                  2. Where can we submit bugs? Upstream doesn't like bugs for experimental CIK support, so on the FDO website and to AMD directly?

                    I don't have any problem with radeon and fglrx drivers they work fine i didn't test with upstream driver of amdgpu yet
                    DAL don't identify the monitor and tv and stuck at 1068x768 i tried with ubuntu 14.04.4 and debian 8 (screens dead with IgnoreEDID option)

                      CIK support is in the driver but disabled upstream by default. SI support is not in the driver yet, although one of our devs and one community dev have been doing some work on it. We're working out next steps now.
