The KPI kexts are loaded through a launchd script with the kexload -v argument. The Info.plist files of both kexts are globally the same (names differ). On Leopard, when I look at system.log, one of KPI is said to not have any personality while there's no complaint for the other. >From the information I gather, I think it would be better if I remove the IOKit kext and merge it into the kext that depends on it.

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Is there supposed to be a defined launch order for launchd and IOKit kexts? Not in the traditional sense. We have IOKit APIs to accomplish the ordering you may desire. >From what I can see on Leopard, launchd can launch daemons before all the IOKit kexts are loaded. I then have one question if the answer is that these 2 processes can run at the same time: If you load a IOKit kext from a launchd script, can it cause trouble when the IOKit startup procedure tries to launch it just before that or just after that? IOKit vends APIs to dynamically be notified on the availability of hardware/drivers. In today's hot-plug world, I'd suggest that you modify your program to use those APIs. Once you've done that, the use of launchd does not change the outcome of your program. This email sent to site_archiver(a)lists.apple.com

For kexts, it is documented here: (I just went to <http://developer.apple.com> and searched for "Personality") <http://developer.apple.com/documentation/DeviceDrivers/Conceptual/ IOKitFundamentals/Matching/chapter_5_section_2.html> Basically, it is a dictionary in your kext's plist that is used to drive IOKit's passive matching. Also, when the driver goes through active matching, the contents of the personality is passed to the driver as its initial property list. Note that any given kext can have several personalities, each offering different matching criteria, and possibly other data left as hints to the driver object that gets run later. This is why they are called "personalities", since one kext can match on several different kinds of devices and can alter its behavior based on the selected personality. Also, your kext only has to contain personalities if it is going to participate in IOKit matching. IOKit families typically don't have personalities since they are loaded as libraries for other kexts, and non-IOKit kexts obviously don't have personalities. I'll let somebody else address StartupItems. OK, but then why does Leopard tells me a kext that is not related to IOKit has no personalities? This email sent to site_archiver(a)lists.apple.com

Please file a bug with Apple's bugreporter so that it gets more weight. A reported workaround seems to be to set the output bit depth in the X11 Preferences to "Thousands of colors". That does the trick. Funny how the X11 message implicates the program has a bug... This email sent to site_archiver(a)lists.apple.com
