Selvaraj You need know the EDKII ATA stack hierarchy first. I would suggest you dig into every module's INF file which describes the module's behavior.
AtaPassThruDxe driver consumes IDE_CONTROLLER_INIT and produces ATA_PASS_THRU & EXT_SCSI_PASS_THRU. AtaBus driver consumes ATA_PASS_THRU to manage/enumerate ATA devices and produces BLOCK_IO and DISK_INFO for every ATA devices. ScsiBus drive consumes EXT_SCSI_PASS_THRU to manage/enumerate ATAPI/SCSI devices and produce SCSI_IO for every ATAPI/SCSI devices. ScsiDisk driver consumes SCSI_IO to produce BLOCK_IO and DISK_INFO for managed ATAPI/SCSI devices. DiskIo driver consumes BLOCK_IO to produce DISK_IO protocol. All of them are needed to be built-in. And the platform you are using must produce IDE_CONTROLLER_INIT protocol. You also need make sure there is no 3rd driver to open those protocol with BY_DRIVER mode.

I could able to find EFI_DISK_INFO protocol implementation in AtaBus driver code. >From EFI_DISK_INFO protocol, we can find the necessary information >(Devicetype,Modelno and etc) as per my requirement. I built this driver code(AtaBusDxe)but while loading this driver, I am always facing the error while opening AtaPassThruProtocol (gEfiAtaPassThruProtocolGuid ) and it returns the status as EFI_UNSUPPORTED. I couldn't able to find the reason for this error. As per my knowledge after successfully installed/opened AtaPassThruProtocol in my driver, I could fetch my required information through EFI_DISK_INFO protocol. I got struck at this point, It would be grateful if you could help me to resolve the same.

If you search EFI_DISK_INFO_IDE_INTERFACE_GUID or EFI_DISK_INFO_AHCI_INTERFACE_GUID keyword, it's easy to find out that DISK_INFO's implementation is in AtaBus driver in MdeModulePkg/Bus/Ata. -----Original Message----- From: Murali Selvaraj [mailto:[email protected]] Sent: Sunday, September 22, 2013 19:19 To: [email protected]; Tian, Feng Subject: FW: Identify IDE devices and device information in UEFI Hi Feng, EFI_DISK_INFO_PROTOCOLprovides a data field called "Interface" (a GUID) that identifies the data format for the Inquiry(), Identify(), and SenseData() functions that it also provides. For IDE mode ,I couldn't find EFI_DISK_INFO_PROTOCOL implementation on my edk2 source code.If it is available for IDE please let me know the source path. As I mentioned , I would like at least to print device type,size of the device . Do I need to include AtaAtapiPassThru protocol or not? Is it possible to include EFI_DISK_INFO_PROTOCOL to my driver? So far,my driver is able to detected controller mode as IDE mode.Please guide me how to proceed from this stage.

Thanks Feng -----Original Message----- From: Murali Selvaraj [mailto:[email protected]] Sent: Saturday, September 21, 2013 11:46 To: [email protected] Subject: [edk2] Identify IDE devices and device information in UEFI Hi All, I am developing UEFI driver which will identify ATA/ATAPI devices information on EFI shell. Find the algorithm of my driver and share your suggestions and ideas. 1. AHCI mode & IDE mode 2. scan PCI devices for class code 0x010601 and 0x0101 3. if AHCI mode, get AHCI bar, and check Ports implement, use ATAPassThru protocol to send Identify cmd 4. if UEFI mode, get command ports and control ports by reading ide controller PCI configure offset 0x10~0x1F. As of now, I have written my driver till this identification (AHCI or IDE mode).For me,IDE controller mode detected (DE controller class code = 0x0101xx). The rest of algorithm to be implemented in my driver : UEFIMode: Command and Control Block the access mode for the IO Space, there IO BARs, defined in the SATA / ATA PCI Configuration Space offset 0x10, 0x14, 0x18, 0x1c, as follows: -Offset 10h-Primary Command Block Base Address -Offset 14h-Primary Control Block Base Address -Offset 18h-Secondary Command Block Base Address -Offset 1Ch-Secondary Control Block Base Address With the help of above registers how can I send IDENTIFY command and other ATA commands to get device present status as well as device information (serial No and Model No). Query: Do I need to use ATAPassThru protocol for IDE mode to send ATA commands to the device? >From SATA / ATA PCI Configuration Space offset 0x10, 0x14, 0x18, 0x1c, (IDE >mode) Shall I send ATA command through this registers? Is ATAPassThru protocol necessary for ide mode to send ATA commands?
