Hi Dave,

Here is the pull request of amdkfd for 4.2

drm-amdkfd-next-2015-05-18:

• Add the interrupts & events modules, including new IOCTLs to create and

wait on events. The HSA RT open source stack is mainly using events to know when a dispatched work has been completed. In addition, this module is a pre-requisite for the next module I'm going to upstream - debugger support

This module also handles H/W exceptions, such as memory exception received through the IOMMUv2 H/W and Bad Opcode exception receieved from the GPU.

• Adding a new kernel module parameter to let the user decide whether he

wants to receive a SIGTERM when a memory exception occurs inside the GPU kernel and the HSA application doesn't wait on an appropriate event, or if he just want to receive notification about this event in dmesg. The default is the latter.

• Additional improvements for SDMA code

• Update my email address in Maintainers file as I'm leaving AMD in two

weeks.

Thanks,

    Oded
