Hi everyone,
I have an ACER 5536 laptop with an AMD Radeon HD3200 graphic and mainboard M780G chipset.
I have drivers for GPU and main chipset (Sata bridge SB700, USB filter, etc.) for windows. But only have GPU driver for Linux.
On windows 7 and Linux if I don't install provided driver by ACER site or AMD site, mainboard chipset and GPU gets hot. But by installing drivers not.
Also USB port won't provide current more than 100mA (It won't enumerate high power consumption USB devices like external hard-drives) without installing chipset driver for USB filter chip. So I realized that although I get my laptop working under Ubuntu or Windows, it won't work good without installing all drivers. The problem is that there's no chipset driver anywhere for working under linux. Proprietary drivers are all for windows except little graphic, audio, wireless drivers for Linux.
I also have the same problem with my desktop. The MSI K9n Neo V2 main board with NVIDIA nForce 520 chipset won't enumerate High power USB devices under linux.
Are there any solutions for this problem?
For the laptop, have you downloaded the Linux driver package from www.amd.com (look under Products and Technologies/Netboots and notebooks, then click on the drivers link at the top right of the page).
For the desktop, have you downloaded the Linux driver package from the nvidia website?

Sure. But only GPU driver. Theres no MAINBOARD CHIPSET driver exists on both sites. Drivers are for Graphic processors only. For Windows users it differs. They have the right to have a file like setup.exe to install all needed drivers for USB, South-Bridge and GPU all in one for them. But us? I didn't find a complete pack there. Only GPU supported.
Should I write a kernel module to better support AMD SB700 chipset on my laptop?
I even followed searches lead me to a kernel source change since 2007 as below:
Code:
268 /* ATI */
269 { PCI_VDEVICE(ATI, 0x4380), board_ahci_sb600 }, /* ATI SB600 */
270 { PCI_VDEVICE(ATI, 0x4390), board_ahci_sb700 }, /* ATI SB700/800 */
is this means that they told the linux kernel to treat SB700 chips just like SB600 ones? Can this be the problem of chipsets getting HOT?
