ERROR: Could not manipulate system token. #55

Closed rakovskij-stanislav closed 5 years ago

rakovskij-stanislav commented 6 years ago

Dell Latitude E6430. Ubuntu 18.04, Kernel 4.15

Running:

sudo smbios-token-ctl

Getting 29 tokens, and the 30th is error:

  Token: 0x007d - LCD Brightness (Value)
ERROR: Could not manipulate system token.

I was trying to 'patch' /usr/sbin/smbios-token-ctl and successfully escape LCD token, but after this there is the other 'Could not manipulate system token' with many other tokens

Sum up: Got 70 tokens, blacklisted these tokens:

0x007d,"LCD Brightness (Value)"
0x0140,"CPU XD Support (Off)"
0x0141,"CPU XD Support (Enabled)"
0x0146,"USB Wake Support (Off)"
0x0147,"USB Wake Support (Enabled)"
0x014a,"CPU Virtualization (Disabled)"
0x014b,"CPU Virtualization (Enabled)"
0x0152,"Bluetooth Devices (Enabled)"
0x0153,"Bluetooth Devices (Disabled)"
0x017b,"Cellular Radio (Disable)"

and it'is not end. I have not found the option to automatically escape broken tokens. Maybe I did something bad and broke something on my notebook?)

PS - my target is make my fan work full speed, 70-80°C without huge load, and over 90-95°C with 2/8 cores used is not pretty good)

So there are several tokens that may be filtered from WMI interface in kernel now. You might be running into problems when these occur. A patch to smbios-token-ctl to handle this situation better would be great.

Hi!

Here is the patch)

$ sudo diff /usr/sbin/smbios-token-ctl*
9,10d8
<   # Some mod by Rakovskij Stanislav, 2018, rakovskij.stanislav@gmail.com
<   #

<         except Exception as e:
<             print("   Kitten exception:", e)
<             print("    Do not worry if this problem is not for every token.\nPossibly you cannot use this token because of your bios does not support it or your OS handle it by self")

If you disallow my greedy 9-10 lines, you can freely cut it) New 234-237 lines allow to bypass raising the exception.

Waiting for answer, Rakovskij Stanislav

Can you please send it as a PR on Github? I think the text might need a little massaging too.

Done! (It is my first pull request, so exciting) - https://github.com/dell/libsmbios/pull/56
