SATA AHCI issue

SATA AHCI issue

[Shaveta Leekha]

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

Hi,

As per the spec and the code in "AhciMode.c"

  // According to AHCI 1.3 spec, a PRDT entry can point to a maximum 4MB data block.

Does it mean, only one PRD entry is getting transferred successfully?
But as the data I am writing onto SATA HDD is 30MB big, what about the rest of PRDs?
What could be went here?

Thanks and Regards,
Shaveta

Re: SATA AHCI issue

[Tian, Feng]

Hi, Shaveta

No, we will create multiple PRDs if the transfer length is larger than 4M. each PRD could represent a 4M transfer request and the maximum number of PRD for each command is 65535.

How do you access the HDD? At block level or file level? It happens at all HDDs or only one specific brand model?

Thanks
Feng

Re: SATA AHCI issue

[Shaveta Leekha]

Hi Feng,

Yes for 30MB file, multiple PRD entries would have been created.
But I able to write file only upto 4MB size.

The protocol stack I am using is:

Generic AtaBusDxe driver use EfiAtaPassThruProtocol
Generic AtaAtapiPassThru driver consumes "EfiIdeControllerInitProtocol" and produces "EfiAtaPassThruProtocol" which is consumed by generic AtaBusDxe driver
Platform-specific SATA driver that produces "EfiIdeControllerInitProtocol

I am writing SATA HDD at File level.
HDD is formatted with FAT32 which is identified as FileSytem by FATPKG.

Snippet of writing onto SATA HDD Filesystem is pasted below.

Thanks and Regards,
Shaveta

Re: SATA AHCI issue

[Tian, Feng]

Hi, Shaveta

I saw you are using TFTP cmd to do the test? Did you ever test copying file from  usb stick to the SATA HDD?

I just copied a 70M file from usb to SATA and from SATA to SATA. It works well.

Does this issue happen at all of your HDDs or only one specific brand model? Do you have other helpful info for us to narrow down?

Thanks
Feng

Re: SATA AHCI issue

[Shaveta Leekha]

Hi Feng,

Yes, I am using Tftp to get the file on HDD.

Have tried only one HardDisk, will try SATA disk from other vendors also, to get to the root cause.
Will also try copying data from SATA to SATA.

Are PRD entries aligned in EDK2 code base? (I mean they are aligned on which boundary? 16 Byte? 4KB?)

Shaveta

Hi,

As per the spec and the code in "AhciMode.c"

  // According to AHCI 1.3 spec, a PRDT entry can point to a maximum 4MB data block.

Does it mean, only one PRD entry is getting transferred successfully?
But as the data I am writing onto SATA HDD is 30MB big, what about the rest of PRDs?
What could be went here?

Thanks and Regards,
Shaveta

Subject: [edk2] SATA AHCI issue

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

Re: SATA AHCI issue

[Tian, Feng]

PRD entries are organized like AHCI spec Figure 13 said.

Hi Feng,

Yes, I am using Tftp to get the file on HDD.

Have tried only one HardDisk, will try SATA disk from other vendors also, to get to the root cause.
Will also try copying data from SATA to SATA.

Are PRD entries aligned in EDK2 code base? (I mean they are aligned on which boundary? 16 Byte? 4KB?)

Hi, Shaveta

I saw you are using TFTP cmd to do the test? Did you ever test copying file from  usb stick to the SATA HDD?

I just copied a 70M file from usb to SATA and from SATA to SATA. It works well.

Does this issue happen at all of your HDDs or only one specific brand model? Do you have other helpful info for us to narrow down?

Thanks

Yes for 30MB file, multiple PRD entries would have been created.
But I able to write file only upto 4MB size.

The protocol stack I am using is:

Generic AtaBusDxe driver use EfiAtaPassThruProtocol Generic AtaAtapiPassThru driver consumes "EfiIdeControllerInitProtocol" and produces "EfiAtaPassThruProtocol" which is consumed by generic AtaBusDxe driver Platform-specific SATA driver that produces "EfiIdeControllerInitProtocol

I am writing SATA HDD at File level.
HDD is formatted with FAT32 which is identified as FileSytem by FATPKG.

Hi, Shaveta

No, we will create multiple PRDs if the transfer length is larger than 4M. each PRD could represent a 4M transfer request and the maximum number of PRD for each command is 65535.

How do you access the HDD? At block level or file level? It happens at all HDDs or only one specific brand model?

Re: SATA AHCI issue

[Shaveta Leekha]

Hi Feng,

PRD table entries are 16Byte aligned, as specified by AHCI spec also, it has 4 DWs.

I have tried two HDD, but issue is same, TIMEOUT issue.
I have also tried copying one file on SATA HDD to another file on same SATA HDD(filesize > 4MB),
No issue occur in this scenario.

USB support is not yet there on our platform, so couldn't try that scenario.

Still not sure, where could be the issue?

Thanks and Regards,
Shaveta

Re: SATA AHCI issue

[Tian, Feng]

Hi, Shaveta

I saw the Tftp implemention of UefiShell splits the whole procedure to two steps, read the file from tftp sever at first, then write the file to specified destination.

Do you know which step gets the timeout error?

The 1st step is total irrelevant with HDD access. And I didn't see any difference between the 2nd steps and other common write operations. So I am also curious on this. I would suggest you to add debug message to Tftp.c & AhciMode.c to see what happens.

Thanks
Feng

  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
