Hello, I had installed Gentoo in my laptop successfully last weekend. My laptop is Toshiba Satellite L840. I found that my VGA card is Radeon HD 7670M using "lspci -k" command. Therefore, I refer to Gentoo's Radeon wiki page to configure 4.1.15-r1 kernel with TURKS firmware and emerge linux-firmware atom.
However, my new kernel can not load TURKS successfully. I notice that there is an error message with DRM in dmesg's output. It shows [drm:evergreen_init] *ERROR* Failed to load firmware. Why Evergreen ? Is not Northern Islands ? I am sure that the filename I gave is TURKS's firmware in menuconfig. How could I make the dmesg's error message more verbose to debug ? Are there some configurations should I check again ? p.s. I built it in kernel not in modules. Any advice would be greatly appreciated. Regards, Phil
