site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Importance: Normal Hi, In addition to the Filter Scheme, I would like to check a possibility to develop a New Partition Scheme Driver (not a filter scheme). Where can I get the Sample Source Code and Documentation to develop a New Partition Scheme Driver (not a filter scheme)? Thanks!

Sample Filter Scheme (read doesn't work)
by Developer 03 Nov '04

03 Nov '04

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Importance: Normal Hi, I'm trying to implement Filter Scheme using "Sample Filter Scheme" from the Apple's documentation. My driver is successfully loaded, creating a Volume for the partition I created with hdiutil. At this stage I want just to process a content of a buffer in my driver's read()/write() methods. In both methods I allocate a temporary char *myBuff of IOMemoryDescriptor* buffer->getLength() size, pass it to byffer->readBytes() and then send myBuff to IOLog() method that prints it to /var/log/system.log. It works for getProvider()->write() but it shows also the data which is not a content of a file. It DOESN'T work at all for getProvider()->read(). QUESTION 1: Why getProvider()->read() doesn't bring the file data at all? ------------------------------------------------------------------------- It seems that getProvider()->read() doesn't work, since calling buffer->readBytes() in read() before (for debug only) and after getProvider()->read() gives the same junk in myBuff. What is wrong with my read() method? QUESTION 2: How can I know what data is read/written with getProvider()->read/write() ? ---------------------------------------------------------------------------- ----------- IOLog() shows that read/write() receives some strange data which is not a file content. How can I know what data contains buffer? Following is the source code of my read() and write() methods. Any help will be appreciated. Thanks in advance! // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - void com_MyTutorial_driver_MyFilterscheme::read(IOService* /* client */, UInt64 byteStart, IOMemoryDescriptor* buffer, IOStorageCompletion completion) { IOByteCount readBytes; IOByteCount bufLength = buffer->getLength(); char *myBuff = new char[bufLength]; readBytes = buffer->readBytes(0, myBuff, bufLength); IOLog("MyFilterscheme::read BEFORE*** readBytes = %lu byteStart = %lu bufLength = %lu buffer = %s ***\n", (long)readBytes, (long)byteStart, (long)bufLength, myBuff); getProvider()->read(this, byteStart, buffer, completion); readBytes = buffer->readBytes(0, myBuff, bufLength); for (IOByteCount i = 0; i < bufLength - 1; i++) { if (myBuff [i] == 't') if (myBuff [i+1] == 'e') IOLog("MyFilterscheme::read ***FOUND*** buffer @ %lu = %s ***\n", (long)i, myBuff + i); } IOLog("MyFilterscheme::read AFTER *** readBytes = %lu byteStart = %lu bufLength = %lu buffer = %s ***\n", (long)readBytes, (long)byteStart, (long)bufLength, myBuff); delete[] myBuff; } // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - void com_MyTutorial_driver_MyFilterscheme::write(IOService* /* client */, UInt64 byteStart, IOMemoryDescriptor* buffer, IOStorageCompletion completion) { IOByteCount readBytes; IOByteCount bufLength = buffer->getLength(); char *myBuff = new char[bufLength]; readBytes = buffer->readBytes(0, myBuff, bufLength); IOLog("MyFilterscheme::write readBytes = %lu byteStart = %lu bufLength = %lu buffer = %s ***\n", (long)readBytes, (long)byteStart, (long)bufLength, myBuff); getProvider()->write(this, byteStart, buffer, completion); delete[] myBuff; } _______________________________________________ Do not post admin requests to the list.

Porting newbie seeks help with a couple of things

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Greetings, ioctl(dev, HDIO_GET_IDENTITY, &id) Thanks in advance for any help getting this stuff running on OS X. Mike _______________________________________________ Do not post admin requests to the list. They will be ignored. 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… I've been tasked to port a project from Linux to Mac OS X, and am in the process of doing that now. I've run into a few things that I'm not sure about. It's been a long time since I've been in the 'innards' of a Unix platform, and I'm usually a GUI/Framework guy, not a driver/disk developer. My first question is about the correct way to port from Linux ioctl requests to Darwin (OS X). What I have on Linux right now is a call like this: where HDIO_GET_ENTITY and id, which is a hd_driveid struct, are defined in /linux/hdreg.h. If I copy this file from a Linux box, things will compile, but I'm guessing that the request definition and struct might be used differently on the Mac. Is there any info on the correct way to make this change from Linux? I haven't had much searching. My second question is similar: I need to be able to flush the disk (device) and the Linux code does this using ioctl(fd, HDIO_DRIVE_CMD, &flushcmd) where flushcmd is defined: const unsigned char flushcmd[4] = {0xe7,0,0,0} and HDIO_DRIVE_CMD is defined in hdreg.h. Again, with by including the linux header file, things will compile, but I'm not sure they are working. Is there any place I can look to make sure I'm doing this correctly?
