 |
|
Hi,
I'm installing my PCEngines APU2c4 and have the following piece of hw in lshw: | Code: | *-serial UNCLAIMED
description: SMBus
product: FCH SMBus Controller
vendor: Advanced Micro Devices, Inc. [AMD]
physical id: 14
bus info: pci@0000:00:14.0
version: 42
width: 32 bits
clock: 66MHz
configuration: latency=0 |
It's probably not going to be used anytime soon, but I'd like to have everything up and running.
Any ideas as to what I'm missing in the kernel?
lspci -v | Code: | 00:14.0 SMBus: Advanced Micro Devices, Inc. [AMD] FCH SMBus Controller (rev 42)
Subsystem: Advanced Micro Devices, Inc. [AMD] FCH SMBus Controller
Flags: 66MHz, medium devsel |
Also noticed I have the (more or less) same serial/SMBus unclaimed on my older APU1d4 | Code: | 00:14.0 SMBus: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 SMBus Controller (rev 42)
Subsystem: Advanced Micro Devices, Inc. [AMD] SBx00 SMBus Controller
Flags: 66MHz, medium devsel |

You're welcome.
I have a different mobo, but linux drivers are reasonably generic, so it should do the trick. Or at least give you a hint on digging through menuconfig. |

What about running lshw from latest https://sysresccd.org? |

IMHO the "sp5100_tco" kernel module is adequate for this device.
It is AMD/ATI SP5100 Timer/Watchdog, in kernel config:
Device Drivers -> Watchdog Timer Support -> AMD/ATI SP5100 Timer/Watchdog |

Here's how I do install on new unknown to me hardware. First SystemRescueCD as install media, using the latest kernel (alternative kernel from boot menu). From there I run lspci -nnk > /root/lspci to have a record of PCI hardware. When in doubt I will look it up at cateee.net using PCI ID from previous command.
For instance:
| Code: | 00:1f.4 SMBus [0c05]: Intel Corporation Sunrise Point-H SMBus [8086:a123] (rev 31)
Subsystem: ASRock Incorporation Sunrise Point-H SMBus [1849:a123]
Kernel driver in use: i801_smbus
|
The PCI ID's of interest are obviously 8086:a123 and 1849:a123.
cateee.net tells me 8086:a123 driver has been in kernel since 3.18.
