The same prompt existed in arch/i386/Kconfig without help text too but it was later made invisible and automatic by pre-2.6.13 patch "remove special HPET_EMULATE_RTC config option", commit c91096d85c95c6b7fe8d7065e2aa6825e0bdaca9: "We had a user whose apps weren't working correctly because his "rtc" wasn't working fully. For the sake of simplicity, it seems sensible to always enable HPET RTC emulation."
- So, which criteria influence whether HPET_EMULATE_RTC should be enabled on x86_64 or not?
- In case that there is no compelling reason to disable it if its dependencies are satisfied, shouldn't it rather be invisible and automatic like on i386? -- Stefan Richter -=====-=-=== =--= -==== http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
