[PATCH 1/2] MdeModulePkg/SataControllerDxe: Add support for drives in RAID mode


Vitaly Cheptsov
 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3D3118

This resolves the problem of using drivers connected to Intel G33
builtin SATA controller when run from DuetPkg when it can only
be configured in RAID mode through the firmware settings.

Hello Vitaly,

If my understanding is correct, this driver (SataControllerDxe) and the
AtaAtapiPassThru driver are written for non-RAID case only.

Both drivers (especially AtaAtapiPassThru) do not distinguish logic/physical
SCSI channels, which I think only works for the non-RAID case. I am not sure if
this patch series will have an impact to existing RAID drivers.

Hello Hao,

This is for the case when the drives are not used as a RAID, but the controller is initialised in RAID mode. However, you are right that if a dedicated RAID driver is present, it is best to use it instead. To support both cases can we introduce an off-by-default PCD (e.g. TreatRaidAsSata) to workaround this?

Best regards,
Vitaly

Hello Vitaly,

It sounds to me that the controller driver should properly reflect the mode
according to the actual configuration. Is it possible to update the behavior of
the controller driver?

In my opinion, it seems weird to add WA in these general drivers for platform
driver issue. It might also cause confusion for users of AtaAtapiPassThru to
think it has RAID support.

Hao Wu

Hello Hao,

No, it is not possible to change that, since there is no firmware preference for that. The firmware does not support UEFI, and we are running through DuetPkg.

I believe it is not quite a workaround as the fact that an actual RAID array is installed and the fact that a RAID array is supported are separate matters and may not be distinguishable via IS_RAID. At least this is how Intel controllers work to date. A clear name for the PCD should not cause any confusion. If you think TreatRaidAsSata is not great, we could choose ForceRaidAsSingleDrive.

Best regards,
Vitaly

(Looping in Mike and Ray to see if they have additional comments)

Hello Vitaly,

I am okay with introducing a PCD to force the drives behind a RAID mode controller to be used as normal non-RAID devices.
The name PcdForceRaidAsSingleDrive is fine with me.

If no comment from other reviewers:
1. Could you help to change the BZ tracker https://bugzilla.tianocore.org/show_bug.cgi?id=3118 to a "Tiano Feature Requests"?
For me, it looks more like a feature request.

2. Could you help to include 'AtaAtapiPassThru' in the BZ tracker subject for better reference?

3. For Patch 2/2, is there any reason to clear the bits:
EFI_ATA_PASS_THRU_ATTRIBUTES_PHYSICAL
EFI_EXT_SCSI_PASS_THRU_ATTRIBUTES_PHYSICAL
If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.

Best Regards,
Hao Wu

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.

Hao,
Can this change benefit a general use case?

Thanks,
Ray

Subject: RE: [edk2-devel] [PATCH 1/2] MdeModulePkg/SataControllerDxe:
Add support for drives in RAID mode

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this
change.

Hao,
Can this change benefit a general use case?

Hello Ray,

My understanding to the proposed PCD is that drives behind a RAID mode SATA controller can be configured to working in non-RAID mode (acting like individual drives).

As for the DuetPkg, below is a previous comment from Vitaly:
"there is no firmware preference for that (Hao: configure the controller to non-RAID mode). The firmware does not support UEFI, and we are running through DuetPkg."

Best Regards,
Hao Wu



Thanks,
Ray

I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.

If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode. Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives. For this reason, I am not in favor of adding a PCD.

Vitaly Cheptsov
 

Hello,

1. Could you help to change the BZ tracker https://bugzilla.tianocore.org/show_bug.cgi?id=3118 to a "Tiano Feature Requests"?
For me, it looks more like a feature request.

Sure, done.

2. Could you help to include 'AtaAtapiPassThru' in the BZ tracker subject for better reference?

Also done.

3. For Patch 2/2, is there any reason to clear the bits:
EFI_ATA_PASS_THRU_ATTRIBUTES_PHYSICAL
EFI_EXT_SCSI_PASS_THRU_ATTRIBUTES_PHYSICAL
If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.

I am not quite positive why this was needed (the patch was prepared a few months ago), but I will make a comment in V2 when we test it on real hardware. I think it was required to take the right path in the driver.

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.

This is not the DuetPkg from EDK II, but ours[1]. Thus your claim does not apply.

I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.

Agree, but in this case it is not feasible.

If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode.  Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives.  For this reason, I am not in favor of adding a PCD.

Actually some operating systems have to introduce workarounds for this as well, and no, in this particular case the OS does not treat the drive as RAID either.

If there are no other review comments besides the attributes, I will proceed with V2 in the coming days.

Best regards,
Vitaly

Subject: RE: [edk2-devel] [PATCH 1/2] MdeModulePkg/SataControllerDxe:
Add support for drives in RAID mode

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this
change.

Hao,
Can this change benefit a general use case?



Hello Ray,

My understanding to the proposed PCD is that drives behind a RAID mode SATA controller can be configured to working in
non-RAID mode (acting like individual drives).

As for the DuetPkg, below is a previous comment from Vitaly:
"there is no firmware preference for that (Hao: configure the controller to non-RAID mode). The firmware does not support
UEFI, and we are running through DuetPkg."

Best Regards,
Hao Wu




Thanks,
Ray

Hi Michael,

I believe Intel SATA controllers have non-standard lockdown bits, which do not let you reconfigure them as soon as the initialisation is over. Since we start much later (outside of the firmware), we can no longer control this.

Best regards,
Vitaly

Subject: Re: [edk2-devel] [PATCH 1/2] MdeModulePkg/SataControllerDxe: Add support for drives in RAID mode
 
Hello,
 
1. Could you help to change the BZ tracker https://bugzilla.tianocore.org/show_bug.cgi?id=3118 to a "Tiano Feature Requests"?
For me, it looks more like a feature request.
 
Sure, done.
 
2. Could you help to include 'AtaAtapiPassThru' in the BZ tracker subject for better reference?
 
Also done.
 
3. For Patch 2/2, is there any reason to clear the bits:
EFI_ATA_PASS_THRU_ATTRIBUTES_PHYSICAL
EFI_EXT_SCSI_PASS_THRU_ATTRIBUTES_PHYSICAL
If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.
 
I am not quite positive why this was needed (the patch was prepared a few months ago), but I will make a comment in V2 when we test it on real hardware. I think it was required to take the right path in the driver.
 
DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.
 
This is not the DuetPkg from EDK II, but ours[1]. Thus your claim does not apply.
 
I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.
 
Agree, but in this case it is not feasible.
 
If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode.  Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives.  For this reason, I am not in favor of adding a PCD.
 
Actually some operating systems have to introduce workarounds for this as well, and no, in this particular case the OS does not treat the drive as RAID either.
 
If there are no other review comments besides the attributes, I will proceed with V2 in the coming days.
 
Best regards,
Vitaly

Unfortunately not. That is basically the issue. When there is a preference, it is possible to ask the user to set it. However, for certain Dell machines, we have an issue with, it is not possible to select AHCI mode in the firmware preferences, and these users end up with unconfigurable RAID.

Best regards,
Vitaly

Hao,
Can this change benefit a general use case?


Hello Ray,

My understanding to the proposed PCD is that drives behind a RAID mode SATA controller can be configured to working in
non-RAID mode (acting like individual drives).

As for the DuetPkg, below is a previous comment from Vitaly:
"there is no firmware preference for that (Hao: configure the controller to non-RAID mode). The firmware does not support
UEFI, and we are running through DuetPkg."

Best Regards,
Hao Wu





Thanks,
Ray

So those types of systems must have a RAID enabled FW driver.  Right?  So the drives could be configured as a RAID set and using the patch you suggest below could corrupt data.

 

It is difficult to support a change that could corrupt data.

Unfortunately not. That is basically the issue. When there is a preference, it is possible to ask the user to set it. However, for certain Dell machines, we have an issue with, it is not possible to select AHCI mode in the firmware preferences, and these users end up with unconfigurable RAID.

Hi Michael,

 

I believe Intel SATA controllers have non-standard lockdown bits, which do not let you reconfigure them as soon as the initialisation is over. Since we start much later (outside of the firmware), we can no longer control this.

 

Best regards,

Vitaly

Hello,

 

1. Could you help to change the BZ tracker https://bugzilla.tianocore.org/show_bug.cgi?id=3118 to a "Tiano Feature Requests"?
For me, it looks more like a feature request.

 

Sure, done.

 

2. Could you help to include 'AtaAtapiPassThru' in the BZ tracker subject for better reference?

 

Also done.

 

3. For Patch 2/2, is there any reason to clear the bits:
EFI_ATA_PASS_THRU_ATTRIBUTES_PHYSICAL
EFI_EXT_SCSI_PASS_THRU_ATTRIBUTES_PHYSICAL
If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.

 

I am not quite positive why this was needed (the patch was prepared a few months ago), but I will make a comment in V2 when we test it on real hardware. I think it was required to take the right path in the driver.

 

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.

 

This is not the DuetPkg from EDK II, but ours[1]. Thus your claim does not apply.

 

I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.

 

Agree, but in this case it is not feasible.

 

If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode.  Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives.  For this reason, I am not in favor of adding a PCD.

 

Actually some operating systems have to introduce workarounds for this as well, and no, in this particular case the OS does not treat the drive as RAID either.

 

If there are no other review comments besides the attributes, I will proceed with V2 in the coming days.

 

Best regards,

Vitaly

Not correct, these systems do not have hard RAID support or anything alike. It is standard G45 from what I remember. I believe the vendor simply left the firmware supplier defaults or something alike as there is a way to use IDE mode but nothing for AHCI.

Unfortunately not. That is basically the issue. When there is a preference, it is possible to ask the user to set it. However, for certain Dell machines, we have an issue with, it is not possible to select AHCI mode in the firmware preferences, and these users end up with unconfigurable RAID.

 

Best regards,

Vitaly

But do the systems allow the user to configure the FW that runs earlier?  Can you require to users to configure their platforms correctly?

Hi Michael,

 

I believe Intel SATA controllers have non-standard lockdown bits, which do not let you reconfigure them as soon as the initialisation is over. Since we start much later (outside of the firmware), we can no longer control this.

 

Best regards,

Vitaly

Subject: Re: [edk2-devel] [PATCH 1/2] MdeModulePkg/SataControllerDxe: Add support for drives in RAID mode

 

Hello,

 

1. Could you help to change the BZ tracker https://bugzilla.tianocore.org/show_bug.cgi?id=3118 to a "Tiano Feature Requests"?
For me, it looks more like a feature request.

 

Sure, done.

 

2. Could you help to include 'AtaAtapiPassThru' in the BZ tracker subject for better reference?

 

Also done.

 

3. For Patch 2/2, is there any reason to clear the bits:
EFI_ATA_PASS_THRU_ATTRIBUTES_PHYSICAL
EFI_EXT_SCSI_PASS_THRU_ATTRIBUTES_PHYSICAL
If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.

 

I am not quite positive why this was needed (the patch was prepared a few months ago), but I will make a comment in V2 when we test it on real hardware. I think it was required to take the right path in the driver.

 

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.

 

This is not the DuetPkg from EDK II, but ours[1]. Thus your claim does not apply.

 

I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.

 

Agree, but in this case it is not feasible.

 

If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode.  Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives.  For this reason, I am not in favor of adding a PCD.

 

Actually some operating systems have to introduce workarounds for this as well, and no, in this particular case the OS does not treat the drive as RAID either.

 

If there are no other review comments besides the attributes, I will proceed with V2 in the coming days.

 

Best regards,

Vitaly

Can this change benefit a general use case?



Hello Ray,

My understanding to the proposed PCD is that drives behind a RAID mode SATA controller can be configured to working in
non-RAID mode (acting like individual drives).

As for the DuetPkg, below is a previous comment from Vitaly:
"there is no firmware preference for that (Hao: configure the controller to non-RAID mode). The firmware does not support
UEFI, and we are running through DuetPkg."

Best Regards,
Hao Wu






Thanks,
Ray

As long as we do not write to a RAID array it will not cause any issues, and we do not. So I do not see an issue here.

Not correct, these systems do not have hard RAID support or anything alike. It is standard G45 from what I remember. I believe the vendor simply left the firmware supplier defaults or something alike as there is a way to use IDE mode but nothing for AHCI.

If the drives are intended to be used as non-RAID devices, I think both the ATTRIBUTES_PHYSICAL & ATTRIBUTES_LOGICAL should be set for the controller according to the UEFI Spec.

 

I am not quite positive why this was needed (the patch was prepared a few months ago), but I will make a comment in V2 when we test it on real hardware. I think it was required to take the right path in the driver.

 

DuetPkg was removed from edk2.
If the change is specially for DUET use case, I am afraid we cannot accept this change.

 

This is not the DuetPkg from EDK II, but ours[1]. Thus your claim does not apply.

 

I agree it would be better to configure the platform so the SATA controller is in its non-RAID mode.

 

Agree, but in this case it is not feasible.

 

If the controller is in RAID mode, then the OS that is booted may have a SATA RAID driver
that can configure the drives in RAID mode.  Then, if the UEFI FW treats it as non RAID, it
may not be bootable, and configuration actions in UEFI may corrupt data on the RAID configured
drives.  For this reason, I am not in favor of adding a PCD.

 

Actually some operating systems have to introduce workarounds for this as well, and no, in this particular case the OS does not treat the drive as RAID either.

 

If there are no other review comments besides the attributes, I will proceed with V2 in the coming days.

 

Best regards,

Vitaly

Hao,
Can this change benefit a general use case?



Hello Ray,

My understanding to the proposed PCD is that drives behind a RAID mode SATA controller can be configured to working in
non-RAID mode (acting like individual drives).

As for the DuetPkg, below is a previous comment from Vitaly:
"there is no firmware preference for that (Hao: configure the controller to non-RAID mode). The firmware does not support
UEFI, and we are running through DuetPkg."

Best Regards,
Hao Wu






Thanks,
Ray

Add



support for drives in RAID mode

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3118

This resolves the problem of using drivers connected to Intel G33
builtin SATA controller when run from DuetPkg when it can only be
configured in RAID mode through the firmware settings.
