Linux 6.13 was AMD 3D V-Catch Optimizer Driver for Dana because AMD was able to affect the Dana scheduling decisions on processors where only CCDS subset has more than 3D V-catch. With this new driver, users can talk to their cache vs. frequency preferences where new tasks are previously kept if with a large L3 cache on CCD or with high frequency capacity. Take a look at the effects of the use of AMD 3D V-Catch Optimizer Driver with the new AMD Ryzen 99950x3d here.
The AMD posted the 3DV catch Optimizer driver for Linux last October and now Raisen is the first new AMD product with the 9950x3D launch because the driver had the opportunity to return to Linux 6.13 to be able to use it. The driver’s SYSFS interface can be fixed to affect the rehabilitation of the Cashes vs. Frequency CPU Core, depending on whether you are trying to keep a high frequency CCD or large cache (3D V-catch) on CCD.
Linux 6.13+ and when the Dana is built with AMD_3D_VCACA KCONFIG Option, Raizen X3D processor is possible to read by Raizing 9950x3d on Raisin 9950X3D /SYS/Bus/Platform/Driver/AMD_X3D_VCACHE/AMDI0101 : 00/AMD_X3D_MODE SYSFS interface. Raizen was used as a default preference for 9950x3d as a default. But if writing “cache” /SYS/Bus/Platform/Driver/AMD_X3D_VCACHE/AMDI0101 : 00/AMD_X3D_MODE It would prefer to use CCD with large cache. For those who are interested in this cash vs. Frequency can be easily manipulated at a run time.
Yesterday’s Raisen 9950x3D Linux reviews all CPUs were begun on their defaults at Linux 6.13. For this article, the 3DV catch is running through a “cache” mode with the drivers with a 3 -DV catch optimizer driver. No other changes were made to the system during the test, and the priority of Kesha was not chosen.
Let’s see how this 3DV catch optimizer drivers change affects the new Raisin 9950x3d under Linux. Benchmark results with “- X3D Optimizer Cash” are new runs using a 3D V-Catch Optimizer preference.
