Date: Thu, 11 Oct 2007 08:01:32 -0400 From: Rick Niles <fniles@...pooh.org> To: linux-kernel@...r.kernel.org Subject: Help with rtc to hpet conversion of OSGPS driver I'm the Linux maintainer for the OSGPS (open source GPS) project. Our last release version was based off Fedora 5 and since we have had some hardware issues with our on board interrupt line I was using the RTC interrupt to service the tracking loops. I've been trying to make the driver work with Fedora 7 and the 2.6.22 kernel, but the rtc_register() and other RTC functions seems to have been removed. I see they've been replaced by the corresponding HPET functions, which is great. However, hpet_register() always returns -16 (EBUSY). This could be because I lack the correct hardware (I'm running 32-bit Linux on a Athlon64 with an NVIDIA chipset) or some other reason. I'm looking for any help here. The RTC version of the code can be viewed at: http://osgps.cvs.sourceforge.net/osgps/osgps/linuxmod.c?revision=1.12&view=markup Can device drivers still use the real-time clock at all? Does the tickless kernel effect this at all? Thanks for any help you can lend, Rick Niles. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
