In addition, I believe the timeouts in the Linux i2c-piix4.c driver are unnecessarily high and would like to have them reduced or at least a userspace-accessible option to reduce them. With the current Linux driver on kernel 4.15.0-45, this second bus is not detected and as such I cannot control the motherboard's Aura lighting. I discovered that the RAM controllers are on the first bus at 0x0B00 (which also has the SPD EEPROMs) while the motherboard's Aura controller is on the second bus at 0x0B20. This seems to be the case with at least X470 and X399 as well, according to GitLab user reports. In doing this research, I learned that the AMD X370 chipset actually has two PIIX4-compatible SMBus controllers, one at I/O 0x0B00 and one at I/O 0x0B20. I also utilized the Linux I2C code along with InpOut32 on Windows to drive the SMBus controllers from userspace and control the lighting without the official application. I have reverse engineered much of the Aura controller's register map and have code to configure and set colors to the module from Linux. This RGB lighting system uses the SMBus interface to communicate with lighting controllers on the motherboard and RAM modules. I've been working on reverse engineering Asus and friends' Aura RGB lighting system that is found on many Asus motherboards along with DDR4 RAM modules from G.Skill, ADATA, and others.

But we have had a couple of null drivers shipped via Windows Update within the last months, that's causing serious issues. In normal cases, a null driver shall not harm. I don't know, why Microsoft intended to ship this driver package via Windows Update (and especially without providing any details). The file SMBUSAMD.cat just contains a digital signature. The new update installs an Null driver via SMBUSAMD.inf. So if device manager shows an unknown device with the hardware id enlisted above, the driver will fix this issue. The reason, why this driver exists: Windows 'thinks' it need such a driver. The driver belongs to the mainboard and the chipset. According to Wikipedia it helps to detect the state of several components. SMBus stands for System Management Bus, a two line bus used for communication between ICs. The driver package is 30 KB in size and release notes say, the driver is for Advanced Micro Devices, Inc Other hardware::ĭescription: Advanced Micro Devices, Inc Other hardware software update released in January, 2015ĭriver Manufacturer: Advanced Micro Devices, Incĭriver Provider: Advanced Micro Devices, Inc I checked Microsoft Update Catalog and found the driver is offered for all supported Windows platforms.
