SATA AHCI issue

[Shaveta Leekha <shaveta.leekha@nxp.com>]

Hi,

I am facing one Timeout issue while writing
big file over my SATA HDD.
It in the code of "AhciDmaTransfer " from file AhciMode.c

  //
  // Wait for command compelte
  //
  FisBaseAddr = (UINTN)AhciRegisters->AhciRFis + Port * sizeof (EFI_AHCI_RECEIVED_FIS);
  Offset      = FisBaseAddr + EFI_AHCI_D2H_FIS_OFFSET;
Status = AhciWaitMemSet (
               Offset,
               EFI_AHCI_FIS_TYPE_MASK,
               EFI_AHCI_FIS_REGISTER_D2H,				This MemSet check fails, what could be the issue?
               Timeout
               );

TimeOut occur while checking FIS_REGISTER_D2H.
Any idea about this time out issue?

Can it be "Due to un-aligned PRD? Are there multiple PRDs created or single PRD?"

As I am able to write maximum 4MB file on SATA HDD, file above 4MB size failed by giving TIMEOUT_ERROR.

Thanks and Regards,
Shaveta
