I found out that the cause of the kernel panic is from my code "OSSafeReleaseNULL(ivars->pciDevice);" But after removing it, the system is still not as expected. After a hot unplug, the Thunderbolt cable was plugged in again and the PCIe Device Controller never came back. My DEXT user space driver is never loaded again. Only reboot the system once.

Your dext driver needs to create two iigs, one for your user space driver and one for your iouserclient. Your user space driver can be written like this. . . . kern_return_t IMPL( MyUserSpaceDriver, NewUserClient ) { if(ivars->MyIoUserClient==NULL) { IOService *client = nullptr; if(IOService::Create(this /* provider */, "MyIOUserClientProperty" /* IOPropertyName */, &client)!=kIOReturnSuccess) { return (kIOReturnError); } ivars->MyIoUserClient = (MyIOUserClient *) OSDynamicCast(IOUserClient, client); if(ivars->MyIoUserClient==NULL) { client->release(); return kIOReturnError; } } *userClient = ivars->MyIoUserClient; return (kIOReturnSuccess); } kern_return_t IMPL( MyUserSpaceDriver, Start ) { ........ if(ivars->MyIoUserClient==NULL) { IOService *client = nullptr; if(IOService::Create(this /* provider */, "MyIOUserClientProperty" /* IOPropertyName */, &client)!=kIOReturnSuccess) { goto start_fail; } ivars->MyIoUserClient = (MyIOUserClient *) OSDynamicCast(IOUserClient, client); if(ivars->MyIoUserClient==NULL) { client->release(); goto start_fail; } ivars->MyIoUserClient->Start(this); } ..... } If it is simply the Class used by the user space driver, it can be called in the form of namespace. namespace { class RingBuffer { public: void init(int desiredSize) { size=desiredSize + 1; data=(char *)IOMalloc(size); head=0; tail=0; return; } void deinit(void) { if(data != NULL) { IOFree(data, size); data=NULL; } return; } private: int head, tail, size; char *data; } }

The dext user space driver I wrote has loaded and got my SCSI controller working. Although there are still some imperfections, on the whole, such a new development environment really requires some patience to adapt.

I got the same error in Xcode 14 "Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile." Must be a bug in Xcode14 Beta 3, the old DriverKit profile is recognized in Xcode 13 but not in Xcode 14.

Hi, Drewbadour You said "XCode14 DriverKit profiles have changed to support DriverKit on iPadOS" Causes the "provisioning profiles" we used in XCode13 to produce "Platform: maOS" in Xcode14 "Doesn't match platform DriverKit" and cannot be used. So does Apple know about this problem and how to fix it? I tried make a new Distribution DriverKit provisioning profiles for Xcode 14, but failed. If Asix, or anyone else, has found a solution to this problem, I hope to respond, thank you!

I got the same error in my thunderbolt SCSI controller project. I've reported this bug to Apple for a long time, but haven't gotten any response until now.

If you try to install Xcode 14 beta, it is limited by hardware and MacOS version. You can use Xcode 12 with MacOS Big Sur.

PCIDriverKit support PCI Device PNP is ready for Intel x86 base. But Not yet Ready for M1 (arm64)

My project can be compiled on other operating systems But there are some systems that have the same problem as you

I have the same problem as you After a few experiences I just realized that this is because I use the same hard drive to compile my project programs back and forth between MacOS X86 / ARM64(M1) Such behavior leads to Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid))
