ARCH_INTEL64_HPET_ALARM is one of the three members of the "System Timer
Source" choice, but selecting it does not build. Taking qemu-intel64:nsh on
master and moving the choice off ARCH_INTEL64_TSC_DEADLINE onto it:
intel64/intel64_hpet_alarm.c:41:24: error:
'CONFIG_ARCH_INTEL64_HPET_ALARM_CHAN' undeclared
ARCH_INTEL64_HPET_ALARM_CHAN lives inside "if INTEL64_HPET" and nothing
selects INTEL64_HPET. Enabling that by hand moves the failure to link time,
because intel64_oneshot_lower.c is built only when INTEL64_ONESHOT is set:
undefined reference to `oneshot_initialize'
Enabling INTEL64_ONESHOT as well finally reaches the real problem.
intel64_oneshot_lower.c implements the counter flavour of struct
oneshot_operations_s, which exists only with ONESHOT_COUNT:
intel64_oneshot_lower.c: error: 'const struct oneshot_operations_s' has no
member named 'start_absolute'
intel64_oneshot_lower.c: error: implicit declaration of function
'oneshot_count_init'
intel64_oneshot_lower.c: error: initialization of
'int (*)(struct oneshot_lowerhalf_s *, const struct timespec *)' from
incompatible pointer type ... (four more of these)
ONESHOT, ONESHOT_COUNT and ONESHOT_FAST_DIVISION were selected by
ARCH_INTEL64_TSC_DEADLINE and by nothing else, so the other members of the
same choice could never be built.
Select the four from ARCH_INTEL64_HPET_ALARM as well. INTEL64_ONESHOT
selects INTEL64_HPET in turn, which is what brings
ARCH_INTEL64_HPET_ALARM_CHAN into existence, so one added select closes all
three stages.
Impact: build only, and only for a configuration that could not be built
before. No existing defconfig selects ARCH_INTEL64_HPET_ALARM.
