2016-10-26gpu-compute: use System cache line size in the GPUTony Gutierrez
2016-10-26gpu-compute: add instruction mix stats for the gpuTony Gutierrez
2016-10-26gpu-compute: remove inst enums and use bit flag for attributesTony Gutierrez
this patch removes the GPUStaticInst enums that were defined in GPU.py. instead, a simple set of attribute flags that can be set in the base instruction class are used. this will help unify the attributes of HSAIL and machine ISA instructions within the model itself. because the static instrution now carries the attributes, a GPUDynInst must carry a pointer to a valid GPUStaticInst so a new static kernel launch instruction is added, which carries the attributes needed to perform a the kernel launch.
2016-10-04gpu-compute: Added method to compute the actual workgroup sizeAlexandru Dutu
This patch adds a method to the Wavefront class to compute the actual workgroup size. This can be different from the maximum workgroup size specified when launching the kernel through the NDRange object. Current solution is still not optimal, as we are computing these for each wavefront and the dispatcher also needs to have this information and can't actually call Wavefront::computeActuallWgSz before the wavefronts are being created. A long term solution would be to have a Workgroup class that deals with all these details.
2016-09-16gpu-compute: Remove WFContextAlexandru Dutu
WFContext struct is currently unused and it has been rendered not useful in saving and restoring the context of a Wavefront. Wavefront class should be sufficient for that purpose and the runtime can figure out the memory size it will need to allocate for a Wavefront through an IOCTL.
2016-06-09gpu-compute: parametrize Wavefront sizejkalamat
Eliminate the VSZ constant that defined the Wavefront size (in numbers of work items); replaced it with a parameter in the GPU.py configuration script. Changed all data structures dependent on the Wavefront size to be dynamically sized. Legal values of Wavefront size are 16, 32, 64 for now and checked at initialization time.
