2016-05-20MdeModulePkg ScsiDiskDxe: Add Erase Block Protocol support for UFS devicesHao Wu3-27/+761
This patch implements the EFI_ERASE_BLOCK_PROTOCOL in ScsiDiskDxe driver. For now, the codes support the erase block feature only on Universal Flash Storage (UFS) devices.

2016-05-05MdeModulePkg: ScsiDiskDxe: cope with broken "Supported VPD Pages" VPD pageLaszlo Ersek1-0/+37
The USB flash drive with Vendor ID 0x1516 (CompUSA) and Product ID 0x6221 returns a broken "Supported VPD Pages" VPD page. In particular, the PageLength field has the invalid value 0x0602 (decimal 1538). This prevents the loop from terminating that scans for the Block Limits VPD page code in ScsiDiskInquiryDevice(): for (Index = 0; Index < PageLength; Index++) { because the Index variable has type UINT8, and it wraps from 255 to 0, without ever reaching PageLength (1538), and because EFI_SCSI_PAGE_CODE_BLOCK_LIMITS_VPD does not occur at offsets 0 through 255. * The fix is not to change the type of Index to UINT16 or a wider type. Namely, section 7.8.14 Supported VPD Pages VPD page in the "SCSI Primary Commands - 4" (SPC-4) specification names the following requirement: The supported VPD page list shall contain a list of all VPD page codes (see 7.8) implemented by the logical unit in ascending order beginning with page code 00h. Since page codes are 8-bit unsigned quantities, it follows that the maximum size for the Supported VPD Pages VPD page is 0x100 bytes, in which every possible page code (0x00 through 0xFF) will be found, before the UINT8 offset wraps around. (EFI_SCSI_SUPPORTED_VPD_PAGES_VPD_PAGE.SupportedVpdPageList is correctly sized as well, in "MdePkg/Include/IndustryStandard/Scsi.h".) * Instead, add sanity checks that enforce the above requirement. If the device breaks the spec, simply fall back to the "Block Limits page absent" case.

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.

In ScsiExecuteSCSICommand(), when SCSI devices do not support non-blocking I/O but an event is passed from caller (UefiScsiLib), the function will execute the SCSI I/O command in a blocking manner and signal the caller event when the command completes. Originally, caller event from UefiScsiLib will be signaled if the SCSI command fails. UefiScsiLib will continue to signal its caller (BlockIO2 request from ScsiDiskDxe driver), which is not aligned with the UEFI spec that event will not be signaled when BlockIO2 request returns with error.

2015-09-10MdeModulePkg: ScsiDiskDxe: adapt SectorCount when shortening transfersLaszlo Ersek1-0/+41
The specification of the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function documents the EFI_BAD_BUFFER_SIZE return status, and the EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN host adapter status. These allow an EFI_EXT_SCSI_PASS_THRU_PROTOCOL implementation to request higher layers in the stack (in this instance, UefiScsiLib and ScsiDiskDxe) to break up the transfer into smaller pieces. These conditions percolate up the stack correctly: the retry loops in ScsiDiskDxe's ScsiDiskReadSectors() and ScsiDiskWriteSectors() functions correctly and transparently update the transfer size (ByteCount), accommodating any shortening requested by lower levels of the stack. After the loop -- if the request ultimately succeeds -- SectorCount is even recalculated from the final ByteCount, to see how many sectors the outer loop should advance. However, the inner (ie. retry) loops both have the same error: when the underlying protocols request the transfer to be shortened, the decrease in transfer size (ie. ByteCount) should immediately be reflected in SectorCount. Otherwise the sector count encoded in the CDB will exceed the transfer size, which is a permanent error. This issue has been witnessed while booting en_windows_8.1_pro_n_vl_with_update_x86_dvd_6051127.iso on the 32-bit build of OVMF, from a virtio-scsi CD-ROM: (1) "cdboot.efi" correctly requested (from far atop) a long read: Timeout=940000000 CdbLength=10 DataDir=Read InTransferLength=134215680 OutTransferLength=0 SenseDataLength=108 Cdb: 28 00 00 00 25 DD 00 FF FF 00 ^ ^^^^^^^^^^^ ^^^^^ | | | | | number of 2KB sectors to read, | | corresponding to 2048 * 65535 = 134215680 bytes | | (see InTransferLength above) | | | LBA to read from | READ (10) (2) In turn, the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function provided by "OvmfPkg/VirtioScsiDxe/VirtioScsi.c" asked for the request to be shortened: InTransferLength=16776704 OutTransferLength=16776704 SenseDataLength=0 HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN TargetStatus=0 Status=EFI_BAD_BUFFER_SIZE (3) Then ScsiDiskReadSectors() in "MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDisk.c" retried the request with correctly shortened transfer length, but incorrectly unchanged sector count: Timeout=940000000 CdbLength=10 DataDir=Read InTransferLength=16776704 <--- updated as requested OutTransferLength=0 SenseDataLength=108 Cdb: 28 00 00 00 25 DD 00 FF FF 00 ^ ^^^^^^^^^^^ ^^^^^ | | | | | not changed! | | | LBA to read from | READ (10) (4) Since 65535 sectors of 2KB each wouldn't fit in a buffer of approx. 16MB, QEMU's virtio-scsi controller unconditionally rejected this request with VIRTIO_SCSI_S_OVERRUN, which VirtioScsiDxe then mapped to: InTransferLength=16776704 OutTransferLength=0 SenseDataLength=0 HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN TargetStatus=0 Status=EFI_DEVICE_ERROR (5) After two more tries of the same, ScsiDiskDxe passed up the error, which ultimately caused "cdboot.efi" to BSOD. Many thanks to Larry Cleeton from Microsoft for helping debug "cdboot.efi".

2011-11-03MdeModulePkg: ATA performance tuning.erictian1-3/+2
1. Boost IDE mode boot when slave device is absent. 2. Use D2H FIS to check if the PIO OUT/DMA IN/DMA OUT transfer is finished or error happened. ATA PIO IN has special check as it may just receive PIO SETUP FIS for success case. 3. Add command status register check for IDE DMA transfer. 4. ScsiDiskReadCapacity() in ScsiDisk should return EFI_SUCCESS if SENSE Data request is success.
