Hi Ard,
I tried using NonDiscoverablePciDeviceDxe driver for SATA (AHCI), but on using
this my SATA drive is not been detected by UEFI.
Below is the reason of error:
>From EnumerateAttachedDevice() function AhciModeInitialization() function gets
>called.
In AhciModeInitialization() under else loop i am receiving EFI_TIMEOUT from
AhciIdentify()
} else if ((Data & EFI_AHCI_ATAPI_SIG_MASK) == EFI_AHCI_ATA_DEVICE_SIG) {
Status = AhciIdentify (PciIo, AhciRegisters, Port, 0, &Buffer);
if (EFI_ERROR (Status)) {
REPORT_STATUS_CODE (EFI_PROGRESS_CODE, (EFI_PERIPHERAL_FIXED_MEDIA |
EFI_P_EC_NOT_DETECTED));
continue;
}
DeviceType = EfiIdeHarddisk;
Then i check In AhciIdentify() function.
Here, AhciPioTransfer() calls AhciCheckMemSet() to read PioFisReceived and
D2hFisReceived.
And AhciCheckMemSet() returns EFI_NOT_READY for both cases.
So timeout occurs.
I tried to compare PciEmulation layer and NonDiscoverablePciDeviceDxe but not
able to find much difference.
Please suggest what can possibly i am missing.
