2015-12-23MdeModulePkg ScsiDiskDxe: Raise the Tpl of async IO callback to TPL_NOTIFYHao Wu
When reading data from non-blockingly from a CD-ROM logic partition, the procedure can be shown by the following call stack: (The write process is similar) |-------------------| | DiskIoDxe (logic) |<---Raise Tpl to TPL_CALLBACK |-------------------| | | Sub-task 1 (UnderRun) succeeds | | |-----------------| |-----------------| |-----------------| +--->| PartitionDxe |---->| DiskIoDxe (Phy) |---->| ScsiDiskDxe | | |-----------------| |-----------------| |-----------------| | | Sub-task 2 (OverRun) fails | | |-----------------| |-----------------| |-----------------| +--->| PartitionDxe |---->| DiskIoDxe (Phy) |---->| ScsiDiskDxe | | |-----------------| |-----------------| |-----------------| | ^ | | More subtasks... Wait indefinitely | |<---Restore Tpl | Completes In PartitionDxe, if the 'Lba' and 'BufferSize' parameters passed to function PartitionReadBlocksEx() are invalid, the function will issue a blocking ReadDisk call (in function ProbeMediaStatusEx()). In DiskIoDxe, blocking I/O request will wait for all the non-blocking I/O requests to complete first before sending down the blocking request. If the Tpl of the async I/O callback in ScsiDiskDxe is TPL_CALLBACK and Sub-task 1 (UnderRun) succeeds but Sub-task 2 (OverRun) fails with an invalid parameter, DiskIoDxe will wait indefinitely for the event created by ScsiDiskDxe of Sub-task 1 to signal. Hence, this commit will raise the Tpl of async IO callback in ScsiDiskDxe to TPL_NOTIFY so that the indefinite wait in DiskIoDxe can be avoided. (Sync patch r19452 from main trunk.)

2015-12-23MdeModulePkg ScsiDiskDxe: Modify FlushBlocksEx() to follow UEFI specHao Wu
The function ScsiDiskFlushBlocksEx() in ScsiDiskDxe/ScsiDisk.c originally always returns EFI_SUCCESS, which is not aligned with the UEFI spec. This commit adds addtional checks to see if the media in the device is changed or removed. Check for whether the device can be written is also added. Corresponding status will be returned according to the check result. (Sync patch r19444 from main trunk.)

transfer length in a single SCSI/ATAPI transfer to reach best device compatibility. Besides this, the patch also fixed: 1) Wrong return value in SenseDataLength field of packet field of EFI_EXT_SCSI_PASS_THRU protocol, it should reflect real sense data length we got. 2) Wrong logic in ScsiDiskRequestSenseKeys that the logic makes SenseData pointer unaligned compared with BlockIo.Media.IoAlign field.
