The UNIX part is simply because that can be built as a module. Is it possible to use an allyesconfig rather than an allmodconfig? That would leave all relevant options built-in. > diff --git a/drivers/tty/hvc/Kconfig b/drivers/tty/hvc/Kconfig > index 4293c172e120..44e23c2388bd 100644 > --- a/drivers/tty/hvc/Kconfig > +++ b/drivers/tty/hvc/Kconfig > @@ -82,6 +82,7 @@ config HVC_UDBG > config HVC_DCC > bool "ARM JTAG DCC console" > depends on ARM || ARM64 > + depends on !KTEST_RUNNABLE > select HVC_DRIVER > help > This console uses the JTAG DCC on ARM to create a console under the > HVC ... this is just a hack around the DCC driver being dodgy. We should fix that to only probe if explicitly requested at run-time via a command line argument. Thanks, Mark.
