From 29a5d3eb9a7612b26ba098a0db65e54372612d07 Mon Sep 17 00:00:00 2001
From: Andrew Lewycky <Andrew.Lewycky@amd.com>
Date: Sun, 7 Dec 2014 17:05:11 +0200
Subject: [PATCH 0121/1050] drm/amdkfd: add events IOCTL set definitions
- AMDKFD_IOC_CREATE_EVENT:
Creates a new event of a specified type
- AMDKFD_IOC_DESTROY_EVENT:
Destroys an existing event
- AMDKFD_IOC_SET_EVENT:
Signal an existing event
- AMDKFD_IOC_RESET_EVENT:
Reset an existing event
- AMDKFD_IOC_WAIT_EVENTS:
Wait on event(s) until they are signaled
v2:
- Move the limit of the signal events to kfd_ioctl.h so it
can be used by userspace
v3:
- Change all bool fields in struct kfd_memory_exception_failure
to uint32_t
