========================================================
Linux Driver for the AMD/Pensando(R) DSC adapter family
========================================================
Copyright(c) 2023 Advanced Micro Devices, Inc
Identifying the Adapter
=======================
To find if one or more AMD/Pensando PCI Core devices are installed on the
host, check for the PCI devices::
# lspci -d 1dd8:100c
b5:00.0 Processing accelerators: Pensando Systems Device 100c
b6:00.0 Processing accelerators: Pensando Systems Device 100c
If such devices are listed as above, then the pds_core.ko driver should find
and configure them for use. There should be log entries in the kernel
messages such as these::
$ dmesg | grep pds_core
pds_core 0000:b5:00.0: 252.048 Gb/s available PCIe bandwidth (16.0 GT/s PCIe x16 link)
pds_core 0000:b5:00.0: FW: 1.60.0-73
pds_core 0000:b6:00.0: 252.048 Gb/s available PCIe bandwidth (16.0 GT/s PCIe x16 link)
pds_core 0000:b6:00.0: FW: 1.60.0-73
Health Reporters
================
The driver supports a devlink health reporter for FW status::
# devlink health show pci/0000:2b:00.0 reporter fw
pci/0000:2b:00.0:
reporter fw
state healthy error 0 recover 0
# devlink health diagnose pci/0000:2b:00.0 reporter fw
Status: healthy State: 1 Generation: 0 Recoveries: 0
Support
=======
For general Linux networking support, please use the netdev mailing
list, which is monitored by AMD/Pensando personnel::
