Motive behind is to make current G5 machine support a new display mode. The ability to override display capabilities exist to some extent but I am not sure if it is documented or supported by Apple for 3rd parties to do. You will find some existing overrides under /System/Library/Displays/Overrides and they are xml files. I presume you could create your own and install them under /Library/Displays/Overrides but I am not sure that is supported. What the bits, etc. mean can likely be understood by looking at Darwin source code. If you cannot find the information you need (maybe others can give you more detailed information) and you need this working quickly try contacting Apple developer technical support for assistance.

I want to know the function exported by the kext file, so that I can place my filter above it by exporting the same interfaces. Like in windows we can disassemble a .drv or .sys file ,similarly any way is there in mac To find functions exported by a kext, the easiest tool to use is nm(1). Once you know the function it can easily be disassembled using gdb(1), e.g.: This email sent to site_archiver(a)lists.apple.com

Passing data from Userland to Kernel
by pratik 21 Apr '05

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com Hi All, I am working on MAC OS 10.3.3. I want to pass the data from User space to the kernel space. For that i am using IOConnectMethodStructureIStructureO. I want to pass the SCSITaskData structure to the user-client from user-space. My SCSITaskData Structure is as follows: typedef struct SCSITaskData { unsigned char CDB[16]; SCSITaskAttribute taskAttribute; unsigned int transfercount; UInt32 scatterGatherEntries; struct iovec scatterGatherList[1]; }SCSITaskData; struct iovec { char *iov_base; /* Base address. */ size_t iov_len; /* Length. */ }; Here in the User-Client i am able to print the data by following code snippet: IOReturn com_SPSOFT_driver_iSCSITargetUserClient::MyDo_Write(void *vIn, void *vOut, void *vInCnt, void * /* vOutCnt */, void *, void *) { IOLog("\n####################################IN USER-CLIENT############################################################\n"); IOReturn ret = kIOReturnSuccess; SCSITaskData * scsitask =(SCSITaskData *) vIn; void *pData; IOMemoryDescriptor* memP; IOLog("\n %x %x %x %x %x %x %x %x %x %x",scsitask->CDB[0],scsitask->CDB[1],scsitask->CDB[2],scsitask->CDB[3],scsitask->CDB[4],scsitask->CDB[5], scsitask->CDB[6],scsitask->CDB[7],scsitask->CDB[8],scsitask->CDB[9]); IOLog("\n\n****************DATA IN USER_CLIENT*************************\n\n"); IOMemoryMap *mMap = NULL; IOReturn retWrite = kIOReturnSuccess; IOMemoryDescriptor* mem = IOMemoryDescriptor::withRanges((IOVirtualRange *)&scsitask->scatterGatherList,(UInt32)scsitask->scatterGatherEntries, kIODirectionOut,fTask,true); IOLog("\n*******************************AFTER IOMemoryDescriptor*******************************\n"); if(!mem ) { IOLog("\ncom_SPSOFT_driver_iSCSITargetUserClient::SPSOFT_readWrite Unable to Map memory \n"); mem->release(); ret= kIOReturnNoMemory; } else { IOLog("\n*******************************Calling Write in driver*******************************\n"); mem->prepare(); IOLog("\n Prepare for mem Succeded....\n"); //mMap = mem->map(kernel_task,0,kIOMapAnywhere,0,scsitask->scatterGatherList[0].iov_len); mMap = mem->map(); if(mMap == NULL) { IOLog("\n Failed to map buffer......\n"); return kIOReturnError; } else { IOLog("\n mMap = %p\n", mMap); IOLog("\n Mapped memory block for buff successfully....\n"); void *pData = mMap->getVirtualAddress(); IOLog("\n *******************************PRINITING PDATA=%s*******************************\n",pData); if(pData == NULL) { IOLog("\n Failed to get Virtual address.....\n"); return kIOReturnError; } } ret = fProvider->SPSOFT_Write(scsitask,mem,&((SCSITaskResult*)vOut)->so,&((SCSITaskResult*)vOut)->taskResult); IOLog("\n*******************************After Write in driver*******************************\n"); mMap->unmap(); mMap->release(); mem->complete(); mem->release(); } if (kIOReturnSuccess != ret) { DEBUG_LOG("%s[%p]::%s - returning err 0x%08x", getName(), this, __FUNCTION__, ret); } else { IOLog("\n Write Completed Successfully !!!!!!!! \n"); } return ret; } Here i am getting the data in the User-Client. Even i am getting the success for WRITE_10 SCSI command. But no data is get written on the disk.

But no data is get written. Do i need to do some other things like vm_allocate(), mach_make_memory_entry() etc? Please help me out. It would be a great Help.
