[coreboot] Re: PSE devices enumeration in corevoot

[Scheithauer, Mario]

Hi Ranga,

It seems currently there are issues with EHL FSP MR2 in connection with the use of PSE.
So please try it with FSP MR1.
The issue is currently under investigation.

Best regards,
Mario

Hi Sheng,

In the coreboot log I see

PCI: 00:1d.0 [8086/4bb3] disabled
PCI: Static device PCI: 00:1d.1 not found, disabling it.
PCI: Static device PCI: 00:1d.2 not found, disabling it.

In the FSP debug log I see

PSE TSN Device: Device Id: 0xFFFF, Vendor Id: 0xFFFF
PSE TSN Device: Device Id: 0xFFFF, Vendor Id: 0xFFFF

Thanks
Ranga

Thanks
Ranga

Hi Sheng,

Thanks for your email and response.

1. Yes I used unsigned binary - PSE_FW that came along with 638228_PSE

2. In Device Tree
 device pci 1d.0 off     end # Intel Programmable Services Engine IPC (local host to PSE)
 device pci 1d.1 on      end # Intel Programmable Services Engine Time-Sensitive Networking GbE 0
 device pci 1d.2 on      end # Intel Programmable Services Engine Time-Sensitive Networking GbE 1

3. This is not an RVP but a platform with EHL SoC and I could boot to OS/Ubuntu with coreboot BIOS

Do these TSN GbE devices need MAC programming? I don't see them enumerated from EFI Shell or in OS/spci

Thanks
Ranga

Hi Ranga,
Are you using Intel RVP? Yes you should at least be able to see the PSE TSN working if the PSE binary is included correctly (remember to include the 'unsigned' PSE binary from Intel), by turning on PSE TSN devices in devicetree.cb:
device pci 1d.1 on end # Intel PSE Time-Sensitive Networking GbE 0
device pci 1d.2 on end # Intel PSE Time-Sensitive Networking GbE 1

Thanks,
Sheng

Hi All,

Did anybody work on Elkhart Lake that comes with PSE Firmware?
I don't see any devices getting enumerated which are under PSE I2C,UART, Gbe,TSN

The logs shows

PSE Firmware Status is A138 read from address FE400034
BIOS: PSE FW is loaded and running

Looks like FSP is disabling PSE devices to enumerate

Is this binary enough for coreboot? PSE_FW.bin
[cid:image001.png@01D8451C.6154FC30]

Appreciate any pointers that would help to enumerate PSE devices in EFI Shell

Thanks
Ranga
