Perfect! -Nathan On May 25, 2007, at 9:15 PM, Jim Guyton wrote: The usual way to pass info to a driver on load is via the dictionary stored in the Info.plist file. The kext loader will copy the data items to the registry and the driver can read it from there. For debugging you can look at the registry with ioreg and/or the developer tools applicatio IORegistryExplorer. -- Jim Guyton On May 25, 2007, at 8:04 PM, Nathan Toone wrote: Thanks! -Nathan _______________________________________________ Do not post admin requests to the list.

(I'm pretty new at kernel development...) I have noticed that kernel modules (I'm specifically working on a socket filter NKE) have parameters passed to their MODULE_START and MODULE_STOP functions. a kmod_info_t * structure and a void *. What do these parameters represent? Is there a way for me to specify data that gets passed to my module on load? If so, how do I set that up? Pointers to documentation would be appreciated as well. I wasn't able to find what I was looking for. This email sent to guyton(a)apple.com This email sent to site_archiver(a)lists.apple.com

Re: SampleFilterScheme for Intel?

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com A progress report and search for ideas. I turned on debugging messages (doh!) and now see the filter initializing. It is completely successful ending with start() being completed. I added more debugging information to verify the return values from various functions including start. All seems well, but still not joy. After a few minutes I begin seeing the message "Still waiting for root device." This seems to indicate that the media object for the child is not being recognized or registered? Any ideas how to check this (at boot time?) What could be missing? Note that the filter appears to work fine if it is not set to Local-Root and other GPT/HFS volumes are mounted.

[darwin-dev] firewire-kdp timeouts, why?

But recently, more often than not, I can no longer attach to my target. The firewire proxy is running, and upon pressing the NMI button, the target machine dutyfully reports "FireWireKDP (v1.3.0) configured as KDP sender/receiver" This is extremely frustrating, and I would appreciate if anyone on this list has some insight into this.

SampleFilterScheme for Intel?
by Duane Murphy 23 May '07

23 May '07

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi Folks, Thanks for the debugging tips. Now for more detail because the debugging isn't helping. :-( I'm writing a file system filter scheme loosely based on SampleFilterScheme. Unfortunately SampleFilterScheme appears to predate GPT (Intel) boot drives. I'd like to have my filter scheme attach to GPT volumes including the system volume. I have been unable to make this happen with the SampleFilterScheme. I have modified the SampleFilterScheme to recognize the HFS partitions of GPT drives. Including code overriding probe() to protect against circular conditions (it advertises what it attaches too). This works fine for non-system disks. If I enable Local-Root including the attach/detachMediaObjectToDeviceTree () code then the system hangs at startup. Verbose mode says "Waiting for file system to mount" or something close. I don't see any logging from the filter scheme at all, but clearly the system is unhappy. Any clues? Has anyone successfully attached a filter scheme to a GPT boot volume? Thanks for any help, ...Duane _______________________________________________ Do not post admin requests to the list. They will be ignored.

I somehow ended up on the Core 2 Duo page halfway through, and it seems they botched the translation of EMT64 by calling it a 32-bit extension in German... *sigh*. The OP only has a Core Duo, though, so I guess while the exact word of my text was faulty, I lucked out and ended up giving the correct answer anyway :-/ This email sent to site_archiver(a)lists.apple.com

The Core Duo does not support x86-64 (aka EM64T). What on Intel's site makes you believe that the Core Duo supports EM64T or that only supporting EM64T doesn't mean it is a 64 bit capable core?
