The basic idea of this patch set is to change hw/rtc/mc146818rtc.c into
target independent code so that the file only has to be compiled once
instead of multiple times (and that it can be used in a qemu-system-all
binary once we get there).
The first patch extracts some functions from the APIC code that will be
required for linking when the mc146818rtc becomes target-independent.
The second patch adds a new way for checking whether the "driftfix=slew"
policy is available or not (since the corresponding #ifdefs in the
mc146818rtc code will be removed).
The third patch then removes the "#ifdef TARGET" switches and turns
the mc146818rtc code into a target-independent file.
The fourth patch just fixes a small cosmetic nit that I discovered along
the way: On systems without mc146818, the "-rtc driftfix=slew" simply
got ignored silently. We should at least emit a warning in this case.
Changes since last iteration:
- Dropped the approach of using a new "slew-tick-policy-available"
property that needs to be set by the machine code (and thus dropped
the clean-up patches from Bernhard from this series since they are
no longer required here now)
- Use a new check in hw/core/qdev-properties-system.c instead
(see the second patch)
Thomas Huth (4):
hw/intc: Extract the IRQ counting functions into a separate file
hw/core/qdev-properties-system: Allow the 'slew' policy only on x86
hw/rtc/mc146818rtc: Make the mc146818 RTC device target independent
softmmu/rtc: Emit warning when using driftfix=slew on systems without
mc146818
