Questions[lspci](ubuntu)

It seems that everything in my Ubuntu is working properly. I just noticed that when I use

lspci

The last three lines are,

01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)

05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller (rev 07`)

06:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5229 PCI Express Card Reader (rev 01)

Why does the last line say "Unassigned class [ff00]" ? Is there anything that I need to install or assign?

I just installed Ubuntu 20.04 on my system, and I'm getting PCIe bus errors on bootup. These errors also occurred on my Linux mint 19 install, so I'm worried it might be something with the hardware. That or the kernel itself. Here's the log:

I've also been having issues with internet access dropping out intermittently and high latency. So I want to figure out if these errors might have something to do with that.

Please tell me if there's any more information I need to provide. Thanks!

Whenever I insert/remove SD card, my ubuntu doesn't recognize those behaviors automatically. I have to run lspci command to manually tell ubuntu about the hardware change.

I want to make my ubuntu automatically detect the SD card. (auto-detecting the hardware change, not auto-mounting the file system)

Here is the detailed steps to use SD card on my ubuntu:

1. Insert SD card to the computer. No new messages on dmesg.
2. Run lspci command on terminal. Then the new messages appear on dmesg.
3. Mount the SD card and do something. When finished, unmount the SD card.
4. Remove SD card physically from the computer. dmesg says nothing about this detachment.
5. Run lspci command again. Then dmesg says mmc0: card aaaa removed.

Some additional information:

• I'm using ubuntu 18.04.3 LTS with RTS5227 card reader.
• No problem with mount, read, write and unmount.

Any suggestions appreciated.

When I run the man lspci command, I get:

 lspci - list all PCI devices

But I don't know what a PCI device is. Can anyone explain?

I have a (desktop) Ryzen 5 2400G in my motherboard (B350) socket, so the iGPU should be detected as a Radeon Vega 11.

But every graphic command I use consider it is a Vega 8 Mobile, which is not even possible as it is a desktop APU.

glxinfo and lspci commands returns "Vega 8 Mobile"

From GUI it is the same, if I look at "details" in "parameters", I get : "AMD® Ryzen 5 2400g with radeon vega graphics × 8"

Actually I don't care that much if the displayed name is wrong but I would really like to make sure I enjoy my 11 graphical units instead of 8!

I'm using the amdgpu drivers with latest MESA and kernel.

Thanks in advance for your help :)
