OS/2 on AMD’s new “Richland” A8 6500T 45W processor

AMD now offers a 45W CPU from the Richland family which was released in the 3/4q 2013. There was again a problem with ACPI like on the Haswell machine, but this time not a crash right from the bootup but a boot problem in stage 2.

OS/2 on the 4th gen. Core i (Haswell)

The new Haswell CPU from Intel is now available and therefore we could run some tests with this new CPU. The tested model of the CPU was a Core i5-4570. OS/2 can work on this kind of CPU but at the moment it looks like there is a SMP problem with the ACPI PSD driver that prevents the use of all CPU cores, thus with only one core enabled everything functions correctly and the system boots just fine.

First contact: OS/2 on Intels new Ivybridge CPU

Intel released the 3rd generation of the Core family code name IvyBridge. On the 7th of may we had luck to get the hands on a new machine with such a CPU, it was shipped with a Core i7-3770. A desktop screenshot running some benchmarks is below.

Most of the things like ahci and network were working fine, but uniaud failed to initialize and the usb 3.0 controllers were still waiting for the right driver. Sysbench was working ok for all but the CPU bench Рit simply froze the system. As it never happened before somebody with a similar CPU can maybe test it and report back. The benchmark result table will be available later, hopefully the next new CPU test will be AMDs already released Mobile Trinity CPU  or the desktop version that will be available in august 2012.

Update July 2012: the CPU bench problem is maybe not related to the IvyBridge CPU itself. There have been some talks about an usb3 driver in the os2world forum. The Trinity Desktop CPU is already available in OEM systems but for end users most likely later than august 2012.
