PS1:
Yes, I am setting PCU_IF_FLAG_SYSMO in osmo-bsc. I do
not fully understand why it even exists. […]
Yes, my quick understanding is that the
flag is used to signal "direct phy". We can make sure that's the case by
checking when osmo-bts sets that flag (eg based on whether it is VTY-configured to use
direct phy or not).
IMHO we should add flags or configurations or whatever to describe per-bts which type it
is so that osmo-pcu knows what to do. something like an enum with 1 field per l1if type:
{
L1IF_ALL_PCUIF,
L1IF_DIRECT_SYSMO,
L1IF_DIRECT_LC15,
L1IF_DIRECT_O2CG,
L1IF_DIRECT_RBS,
}
To start with, perhaps simply rename s/PCU_IF_FLAG_SYSMO/PCU_IF_FLAG_DIRECT_PHY/ if that
makes sense.
In any case, now that we have these "if (fl1h)" conditional blocks, I wonder
whether it really makes sense to have the #ifef ENABLE_DIRECT_PHY around there. It may
make sense to get rid of them in the common paths and simply make the check at runtime.
