Userspace wrapper library called libhsakmt:Ī bash script which checks if kfd is installed correctly

Fedora release is currently unavailable for KFD 1.6.

Kernel image built with Ubuntu 13.10 stock configuration file.

Supports wider range of Kaveri APU types.

Supports both Ubuntu 13.10 and Ubuntu 14.04.

Supports running HSA applications in 32bit mode.

Fix bug in topology code that prevented kfd to load on some Motherboards.

Supports Graphics interop (sharing objects between graphic apps and HSA apps).

Enable allocating memory from GPU local memory for HSA apps.

Supports Ubuntu 14.04 and Fedora 21 (with older kernel).

New Kaveri microcode which supports AQL queues.

That each HSA application can open up to 1024 queues, and there can be up toĥ12 HSA applications simultaneously, compared to a total of 23 queues and 8

Driver now supports over-subscription of queues and processes.

Number of queues per HSA process - default is 128 and maximum is 1024.

Number of HSA processes - default is 32 and maximum is 512.

Added two new kernel module parameters:.

Based on amdkfd code, which is expected to be part of Linux kernel 3.19.Uses new AMD's kernel graphic driver, amdgpu, for Carrizo.Individual wavefronts (not kernels) which execute for >4s may fail.If needed, corresponding parameter for Carrizo is amdgpu.lockup_timeout=0.Disable GPU reset through the linux boot string parameter radeon.lockup_timeout=0.GPU reset on Kaveri can cause system hangs.

Pre-built Fedora 21 builds currently unavailble for this release.Enable segfault for GPU accesses to unmapped ATC memory.Better handling of Ctrl-C for long running kernels.Fixes for process termination and cleanup.Fix mutex acquisition order under HSADebug.Minor fix in libhsathunk for KFDMemory test.Change the unmap latency and queue preempt timeout.Fix debug unregister procedure on process termination.These drivers have been superseded by ROCm Platform now hosted at Radeon Open Compute GitHub Repo To install the new driver follow the instructions at If you want to find out more about ROCm platform and how it uses HSA Technologies you can goto AMD Heterogenous System Architecture (HSA) - Linux amdkfd v1.6.1 release for Kaveri & Carrizo Installation and Configuration guide What's New in kfd v1.6.1
