AMD Does First Release Of HSAKMT Library As Part Of Open-Source HSA
HSAKMT is to AMD's AMDKFD HSA kernel driver as libdrm is to Mesa and the DRM kernel drivers. HSAKMT serves as a thunk library to provide a user-space interface to the AMD HSA Linux kernel driver. AMDKFD has been present since the Linux 3.19 kernel for providing the HSA kernel functionality for Kaveri APUs and newer.
With today's release of HSAKMT 1.0, Kaveri and Carrizo APUs are supported. For those wanting to directly interact with AMD HSA from user-space can now use this library that's compatible with the AMDKFD driver going back to its mainline introduction.
The HSAKMT 1.0 release announcement was made today on xorg-announce and its change-log mentions some of the functionality exposed in this Heterogeneous System Architecture library. Development of HSAKMT is happening via this FreeDesktop.org Git repository.
