drm/amdkfd: Handle VM faults in KFD

2018-07-12T02:32:50Z

1. Pre-GFX9 the amdgpu ISR saves the vm-fault status and address per per-vmid. amdkfd needs to get the information from amdgpu through the new get_vm_fault_info interface. On GFX9 and later, all the required information is in the IH ring 2. amdkfd unmaps all queues from the faulting process and create new run-list without the guilty process 3. amdkfd notifies the runtime of the vm fault trap via EVENT_TYPE_MEMORY Signed-off-by: shaoyun liu Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdkfd: Add the events module

2015-05-19T10:02:26Z

This patch adds the events module (kfd_events.c) and the interrupt handle module for Kaveri (cik_event_interrupt.c). The patch updates the interrupt_is_wanted(), so that it now calls the interrupt isr function specific for the device that received the interrupt. That function(implemented in cik_event_interrupt.c) returns whether this interrupt is of interest to us or not. The patch also updates the interrupt_wq(), so that it now calls the device's specific wq function, which checks the interrupt source and tries to signal relevant events. v2: Increase limit of signal events to 4096 per process Remove bitfields from struct cik_ih_ring_entry Rename radeon_kfd_event_mmap to kfd_event_mmap Add debug prints to allocate_free_slot and allocate_signal_page Make allocate_event_notification_slot return a correct value Add warning prints to create_signal_event Remove error print from IOCTL path Reformatted debug prints in kfd_event_mmap Map correct size (as received from mmap) in kfd_event_mmap v3: Reduce limit of signal events back to 256 per process Fix allocation of kernel memory for signal events Signed-off-by: Andrew Lewycky Signed-off-by: Oded Gabbay
