 Posted: Sat Mar 31, 2012 3:24 pm Post subject: External firmware blobs - rtlwifi/rtl8192cfw.bin |
 |
|
I'm following this guide - > http://en.gentoo-wiki.com/wiki/Lenovo_ThinkPad_x120e#Firmware and I'm trying to compile the kernel, but rtlwifi/rtl8192cfw.bin fails. Should I emerge some other firmware besides the radeon one during installation for the realtek wireless chip?
Thanks. |

| Yeah, uninstall radeon-ucode and install linux-firmware. It contains a whole bunch of firmware, including the radeon and realtek stuff you need. |

Do NOT emerge net-wireless/rtl8192se-firmware.
It does not work with the kernel drive, and is to be removed from the portage.
emerge sys-kernel/linux-firmware instead.
If radeon-ucode blocks linux-firmware, unmerge it, for linux-firmware also provides radeon firmwares. |

Thanks for the reply.
The x120e sports the AMD Fusion chip that includes the HD 6310 Graphics. According to the radeon gentoo wiki http://en.gentoo-wiki.com/wiki/Radeon#Device_Firmware, I have to use the radeon-ucode package. Isn't that the case? Might sound noob-ish, but can I install both radeon-ucode and linux-firmware and get the rtl package from linux-firmware?
| Code: | In general, for cards with R600 (Radeon HD2000) or newer:
emerge x11-drivers/radeon-ucode
And all other cards:
emerge sys-kernel/linux-firmware |

gentian,
linux-firmware contains many freely distributable firmware packages but not all.
I think it contains everything you need. If not, its possible to add to it later.
In some cases the firmware is not in linux-firmware, nor is there an ebuild to fetch and install it.
In such cases you must do it yourself.
Anyway, install linux-firmware, reboot then look in dmesg to see what it says about loaded firmware and missing firmware.

Tried linux-firmware. It won't find the rtl8192cfw.bin firmware for my card  How can they post a guide that is supposed to work on the gentoo wiki while it doesnt work? Maybe there is some other firmware that works and can be satisfied by an ebuild out there? |

gentian,
You say "won't find the rtl8192cfw.bin".
Does that mean the file is not in /lib/firmware/... or it is present but is not loaded ?
If its the former, you need to find it on the web and put it in the right place in /lib/fimware/...
The failure message in dmesg will tell the right place.
If its there but not loaded, there is a gotcha in the kernel configuration and build you should investigate.
When you make the kernel driver built into the kernel, thats configured as <*> the firmware must also be built into the kernel..
When you make the kernel driver as <M> the firmware must be in /lib/firmware/...
The other two options fail as the firmware will not be found.
With the driver built in, /lib/firmware is not available when firmware loading is attempted, as root is not yet mounted.
With the driver as <M>, it can't look inside the kernel binary for firmware as that area of the kernel has already been freed.

Yes, It's probably not included in the linux-firmware ebuild, cause when I compile the kernel it fails. However, I followed the x120e gentoo wiki and there is no mention of the realtek driver anywhere but the guide mentions the rtl firmware:
| Code: | | (radeon/PALM_me.bin radeon/PALM_pfp.bin rtlwifi/rtl8192cfw.bin) External firmware blobs to build into the kernel build |
Also, when following the radeon-ucode guide, it states the following option to be enabled in the kernel:
| Code: | | General setup ---> [*] Enable PCI quirk workarounds |
However, this option only becomes available if I select the: configure standard kernel features option, which disables the Sata configuration option. :/ |

It's there for sure, it's part of linux-firmware. You probably configured the kernel incorrectly. Check that the firmware stuff is exactly as on the wiki page. |

I don't see the same Realtek drivers, as the one's spoted on the wiki.

It's tad confusing, cause if I uninstall the radon-ucode firmware, then my card wouldn't work anymore, would it? I have the hd6310 and according to the radeon wiki, I have to use radeon-ucode. Should I just download the rtl8192cfw.bin file and place it in lib/firmware? Would I need to do anything else after that? eg. How am I supposed to load it? I have selected the driver as a Module in Kernel config. |

I read your 1st post thoroughly but this does not answer my last question. Would there be any conflict with my radeon hd card?
| Code: | In general, for cards with R600 (Radeon HD2000) or newer:
emerge x11-drivers/radeon-ucode
And all other cards:
emerge sys-kernel/linux-firmware |

gentian,
Try this experiment thereare two possible outcomes - neither will harm your Gentoo install, nor your video card working.
Boot normally, then look at the names of the firmware files you have in /lib/firmware/radeon/ You may want to send them to a file for chaling later.
Now remove radeon-uscode | Code: | | emerge -C x11-drivers/radeon-ucode |
and install linux-firmware
| Code: | | emerge linux-firmware |
This will not harm your graphics card operation as the ucode file is loading into the card at boot and stays there until you power off.
Look in /lib/firmware/radeon/ again. Check that the files provided by x11-drivers/radeon-ucode are present.
If they are, you are done, you only need linux firmware. if not, | Code: | | emerge -C linux-firmware && emerge x11-drivers/radeon-ucode |
to get back to where you came from.
Provided you don't reboot ig your firmware is missing, everything will contine to work.
I suspect that your | Code: | In general, for cards with R600 (Radeon HD2000) or newer:
emerge x11-drivers/radeon-ucode
And all other cards:
emerge sys-kernel/linux-firmware |
is out of date information.

Gusar was right all the way from the beginning.. I inserted the wrong string on the kernel config. instead of rtl i did rt1.. Anyways, I'm glad that my kernel compiled fine now. Do I have to declare my wifi interface manually somewhere? I have installed wicd but it won't find any wifi networks. |

gentian,
If you are using wicd, no, do not declare your wireless interface manually.
When it appears inwicd should be able to control it.
Its worth | Code: | | emerge wireless-tools |
so you have iwconfig.
iwconfig does for the wireless elements of a wireless network what ifconfig does for the Ethernet part.
Look in to see what it says about your wireless.
Provided you use WEP or no encrytion at all (don't do either for very long), you can use iwconfig to set up your network from the console.
What doessay about networks around you?
Are there any signs in dmesg that your wireless ever associated with an Access Point?
Do your have a switch or Fn Key option to enable and disable your wireless?

It appears as wlan0 on ifconfig -a but I still don't see any networks when running wicd-curses :/
I get wlan0 Link encap:Ethernet HWaddr 00:56:etc.. and no packets are sent/received.
btw, I have installed wireless-tools. iwlist wlan0 returns 'unknown command wlan0' |

gentian,
Your wireless transmitter seems to be off
Does your system have a physical switch to enabe wireless or perhaps a blue FN key combination?
You can try setting the Tx power with iwconfig and see if you get an error message or if the Tx power setting takes effect.
Maximum permitted values vary from one region of the world to another. Some devides do not support all legal Tx Power values either.
15dBm is a good starting point. The UK permits 27dBm. Higher numbers mean more power and on laptops, reduced time running on the battery.
Read the man page to work out the syntax of the command you need
