Hello,
1. I checked that and you are right. It will invoke callback functions when PPIs are already installed. I removed unnecessary function calls in v3 patch.
2. Moved in v3.
3. Corrected in v3.
4. Aligned in v3.
5. Whole debug removed because of point 1.
6. Code removed - point 1.
Thanks,
Maciej

Subject: RE: [PATCH v2 2/2] MdeModulePkg/AhciPei: Use PCI_DEVICE_PPI to manage AHCI device
1. In the AHCI PEIM entrypoint, after registering the PPI callbacks for:
* gEdkiiPeiAtaAhciHostControllerPpiGuid and
* gEdkiiPeiPciDevicePpiGuid
My take is that there is no need to locate above PPI instances already installed within system (codes in entry point that come after the callback registration).
The current implementation of PeiServicesNotifyPpi (details can be referred at MdeModulePkg\Core\Pei\Ppi\Ppi.c - InternalPeiNotifyPpi) will invoke the callback functions for all the matched PPI instances already installed.
Could you help to double confirm on this in your unit test? Sorry for missing this on the V1 patch.
2. Please help to move the function declaration for:
AtaAhciHostControllerPpiInstallationCallback()
AtaAhciPciDevicePpiInstallationCallback()
from AhciPei.c to AhciPei.h to keep consistency.
3. The function description comments for:
AtaAhciHostControllerPpiInstallationCallback()
AtaAhciPciDevicePpiInstallationCallback()
do not exactly match between their declaration and definition.
4. During the enabling of the HC in function AtaAhciInitPrivateDataFromPciDevice():
Status = PciDevice->PciIo.Attributes (
&PciDevice->PciIo,
EfiPciIoAttributeOperationSet,
EFI_PCI_DEVICE_ENABLE,
NULL
);
Could you help to update the flow to align with AtaAtapiPassThru DXE counterpart when enabling the controller?
MdeModulePkg\Bus\Ata\AtaAtapiPassThru\AtaAtapiPassThru.c - AtaAtapiPassThruStart():
Status = PciIo->Attributes (
PciIo,
EfiPciIoAttributeOperationSupported,
0,
&EnabledPciAttributes
);
if (!EFI_ERROR (Status)) {
EnabledPciAttributes &= (UINT64)EFI_PCI_DEVICE_ENABLE;
Status = PciIo->Attributes (
PciIo,
EfiPciIoAttributeOperationEnable,
EnabledPciAttributes,
NULL
);
}
5. DEBUG ((DEBUG_ERROR, "%a: Using AtaAhciHostControllerPpi to initialize private data.\n", __FUNCTION__));
-> DEBUG ((DEBUG_INFO, "%a: Using AtaAhciHostControllerPpi to initialize
-> private data.\n", __FUNCTION__));
6. I think for AtaAhciInitPrivateDataFromPciDevices(), the below code snippet:
//
// Override the status to continue the for loop
//
Status = EFI_SUCCESS;
is no longer needed. Could you help to check?
Best Regards,
Hao Wu
