2017-01-16drm/amdkfd: fix improper return value on errorPan Bian1-1/+3
In function kfd_wait_on_events(), when the call to copy_from_user() fails, the value of return variable ret is 0. 0 indicates success, which is inconsistent with the execution status. This patch fixes the bug by assigning "-EFAULT" to ret when copy_from_user() returns an unexpected value.

2016-07-03drm/amdkfd: Remove create_workqueue()Bhaktipriya Shridhar1-2/+1
alloc_workqueue replaces deprecated create_workqueue(). create_workqueue has been replaced with alloc_workqueue with max_active as 0 since there is no need for throttling the number of active work items. WQ_MEM_RECLAIM has not been set to because kfd_process_wq will not be used in memory reclaim path. kfd_process_wq is used for delay destruction. A work item embedded in kfd_process gets queued to kfd_process_wq and when it executes it destroys and frees the containing kfd_process and thus itself. This requires a dedicated workqueue because a work item once queued, may get freed at any point of time and any external entity cannot flush the work item. So, in order to wait for such a work item, it needs to be put on a dedicated workqueue. kfd_module_exit() calls kfd_process_destroy_wq which ensures that all pending work items are finished before the module is removed. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty. Hence flush_workqueue has been removed. Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Acked-by: Tejun Heo <tj@kernel.org> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2016-06-03drm/amdkfd: unbind only existing processesOded Gabbay1-25/+35
When unbinding a process from a device (initiated by amd_iommu_v2), the driver needs to make sure that process still exists in the process table. There is a possibility that amdkfd's own notifier handler - kfd_process_notifier_release() - was called before the unbind function and it already removed the process from the process table. v2: Because there can be only one process with the specified pasid, and because *p can't be NULL inside the hash_for_each_rcu macro, it is more reasonable to just put the whole code inside the if statement that compares the pasid value. That way, when we exit hash_for_each_rcu, we simply exit the function as well. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> CC: Stable <stable@vger.kernel.org>

amdkfd wants to know syscall type, not task type. Check directly. Unfortunately, amdkfd is making nasty assumptions that a process' bitness is a well-defined constant thing. This isn't the case on x86. I don't know how much this matters, but this patch has no effect on generated code on x86, so amdkfd is equally broken with and without this patch.

2016-02-27drm/amdkfd: Track when module's init is completeOded Gabbay1-3/+12
Current dependencies between amdkfd and radeon/amdgpu force the loading of amdkfd _before_ radeon and/or amdgpu are loaded. When all these kernel drivers are built as modules, this ordering is enforced by the kernel built-in mechanism of loading dependent modules. However, there is no such mechanism in case where all these drivers are compiled inside the kernel image (not as modules). The current way to enforce loading of amdkfd before radeon/amdgpu, is to put amdkfd before radeon/amdgpu in the drm Makefile, but that method is way too fragile. In addition, there is no kernel mechanism to check whether a kernel driver that is built inside the kernel image, has already been loaded. To solve this, this patch adds to kfd_module.c a new static variable, amdkfd_init_completed, that is set to 1 only when amdkfd's module initialization function has been completed (successfully). kgd2kfd_init(), which is the initialization function of the kgd-->kfd interface, and which is the first function in amdkfd called by radeon/amdgpu, will return successfully only if amdkfd_init_completed is equal 1. If amdkfd_init_completed is not equal to 1, kgd2kfd_init() will return -EPROBE_DEFER to signal radeon/amdgpu they need to defer their loading until amdkfd is loaded.
