I wonder what would be the best option here. The images are necessary, so the last option - not complaining - can be misleading for a user. Concerning shipping them. Pros: - the images are obviously freely distributable (the link above). - the corresponding source code was open-sourced by Sun under various licenses (GPL for hypervisor, BSD for openboot). Cons: - there is no exact tag the the OpenSPARC source tree which would correspond to the binaries. - building them is tricky, because it requires Solaris 9 / SPARC. What do you think would be a better option?

One thing we could do is only warn if !qtest_enabled(). We do this for some other boards that otherwise fail entirely when their BIOS image is not present. This is sufficient for the qtest checks which don't actually try to run code on the guest, but merely interact with it via the qtest protocol. We do ship some other ROMs that are only buildable on the right host hardware, so it's not impossible, but I don't know the details of our rules about what we put in pc-bios/. thanks -- PMM

Yes, I think it's a best option. Don't load any images with the -nodefaults option and fail on missing ones wintout -nodefaults. Is there a failing variant of rom_add_file_fixed (I guess it's not uncommon, but I don't find it in include/hw/loader.h) or do I just check the return status? >> Concerning shipping them. >> Pros: >> - the images are obviously freely distributable (the link above). >> - the corresponding source code was open-sourced by Sun under various >> licenses (GPL for hypervisor, BSD for openboot). >> Cons: >> - there is no exact tag the the OpenSPARC source tree which would >> correspond to the binaries. >> - building them is tricky, because it requires Solaris 9 / SPARC. >> >> What do you think would be a better option? > > One thing we could do is only warn if !qtest_enabled(). > We do this for some other boards that otherwise fail entirely > when their BIOS image is not present.

Who may know them? I see no general maintainer for the pc-bios directory as such in our MAINTAINERS file.

I'd strongly prefer the option to build QEMU's own binaries and distribute them in pc-bios/. Downloading this 190M tarball is a nuisance and depending on their continued existence on the Oracle server is a risk. Where does the dependency on Solaris 9 come from? You should be able to run unmodified Solaris 9 binaries on eg. Solaris 10... Best, Jakub

Actually I sent a patch one month ago: http://lists.gnu.org/archive/html/qemu-devel/2017-01/msg05272.html I think I've waited long enough for nacks. Will send a pull request with it.
