Hardware ======== Processor --------- The processor is an AMD Fusion [C-60][] (dual core, x86-64, 1 GHz; `CONFIG_MK8` option). You can monitor the processor temperature uring the [k10temp][] module (`CONFIG_SENSORS_K10TEMP` option), which communicates with the processor via the PCI bus: $ lspci -k … 00:18.3 Host bridge: Advanced Micro Devices [AMD] Device 1703 Kernel driver in use: k10temp Kernel modules: k10temp … You can find read the [relative][k10-relative] processor temperature in degrees Celsius using sysfs. On my system, I can use: $ cat '/sys/module/k10temp/drivers/pci:k10temp/0000:00:18.3/temp1_input' 75500 You can also get there directly through the PCI interface: $ cat '/sys/devices/pci0000:00/0000:00:18.3/temp1_input' 75500 [lm_sensors][] is a fancier way to monitor temperature: $ sensors k10temp-pci-00c3 Adapter: PCI adapter temp1: +69.0°C (high = +70.0°C) (crit = +115.0°C, hyst = +107.5°C) radeon-pci-0008 Adapter: PCI adapter temp1: +69.0°C Graphics -------- Radeon [Evergreen][] IGP ([HD 6290][hd6290]) integrated into the C-60 processor (`radeon` module, `CONFIG_DRM_RADEON` and `CONFIG_DRM_RADEON_KMS` options). Audio ----- Builtin ATI soundcard and ATI Azalia. Both sound cards use [Intel's HDA interface][HDA]: 00:01.1 Audio device: ATI Technologies Inc Device 1314 Subsystem: Acer Incorporated [ALI] Device 0598 Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40) Subsystem: Acer Incorporated [ALI] Device 0598 Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel In order to get these working with [ALSA][], I had to adjust the default soundcard by adding `/etc/asound.conf`: pcm.!default { type hw card SB } ctl.!default { type hw card SB } following [this FAQ][ALSA-26]. You may also want to enable the `dmix` plugin, to enable software mixing of multiple streams (e.g. to play two songs at the same time). I haven't bothered yet, but Pedro Venda discusses the setup [here][dmix]. If you haven't enabled the plugin, you may get errors like: $ ogg123 -q test.ogg & $ ogg123 -q test.ogg === Could not load default driver and no driver specified in config file. Exiting. Networking ---------- The wired network card is an Atheros/Attansic [AR8152][] (`atl1c` module, `CONFIG_ATL1C` option; Atheros [aquired Attansic][attansic] in 2007). The wireless network card is a Broadcom [BCM4313][] (`brcmsmac` module, `CONFIG_BRCMSMAC` option). The Broadcom drivers [require firmware][brcm-firm], which you can get from `git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git` (or `sys-kernel/linux-firmware` on [[Gentoo]]). You'll need to install `bcm43xx-0.fw` and `bcm43xx_hdr-0.fw` into `/lib/firmware/brcm`. Despite the name similarity, this is not the firmware installed by Gentoo's `net-wireless/b43-firmware` package (which fills in `/lib/firmware/b43`). There is also difficulty running both the `atl1c` and `brmcsmac` drivers at the same time. Upon associating with a wireless access point, the kernel (3.2.0-rc2) [hangs][net-mod-hang], forcing a hard-reboot. To avoid this issue, it's wise to remove the `atl1c` module before attempting to connect to a wireless access point. For example: # /etc/init.d/net.eth0 stop # /etc/init.d/net.wlan0 stop # modprobe -r atl1c # modprobe -r brcmsmac # modprobe brcmsmac # /etc/init.d/net.wlan0 start I'm not sure if re-loading the `brcmsmac` module accomplishes anything here, but it can't hurt ;). Another `brcmsmac` limitiation is that it [only supports managed and monitor interfaces][brcmsmac-interfaces] (no master, ad-hoc, etc.). Webcam ------ The Suyin webcam is fairly standard, supporting the [USB video class][UVC] for video4linux (`uvcvideo` module, `CONFIG_USB_VIDEO_CLASS` option). Card reader ----------- I haven't tested the Realtek [RTS51xxx][] card reader yet, but it uses the `ums_realtek` module (`USB_STORAGE_REALTEK` option).
