From 8dc1db3172ae2f17ae71e33b608a33411ce8a1aa Mon Sep 17 00:00:00 2001 From: Mukul Joshi Date: Wed, 14 Sep 2022 16:39:48 +0800 Subject: drm/amdkfd: Introduce kfd_node struct (v5) Introduce a new structure, kfd_node, which will now represent a compute node. kfd_node is carved out of kfd_dev structure. kfd_dev struct now will become the parent of kfd_node, and will store common resources such as doorbells, GTT sub-alloctor etc. kfd_node struct will store all resources specific to a compute node, such as device queue manager, interrupt handling etc. This is the first step in adding compute partition support in KFD. v2: introduce kfd_node struct to gc v11 (Hawking) v3: make reference to kfd_dev struct through kfd_node (Morris) v4: use kfd_node instead for kfd isr/mqd functions (Morris) v5: rebase (Alex) Signed-off-by: Mukul Joshi Tested-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Hawking Zhang Signed-off-by: Morris Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c') diff --git a/drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c b/drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c index 5c8023cba196..4ebfff6b6c55 100644 --- a/drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c +++ b/drivers/gpu/drm/amd/amdkfd/cik_event_interrupt.c @@ -26,7 +26,7 @@ #include "amdgpu_amdkfd.h" #include "kfd_smi_events.h" -static bool cik_event_interrupt_isr(struct kfd_dev *dev, +static bool cik_event_interrupt_isr(struct kfd_node *dev, const uint32_t *ih_ring_entry, uint32_t *patched_ihre, bool *patched_flag) @@ -85,7 +85,7 @@ static bool cik_event_interrupt_isr(struct kfd_dev *dev, !amdgpu_no_queue_eviction_on_vm_fault); } -static void cik_event_interrupt_wq(struct kfd_dev *dev, +static void cik_event_interrupt_wq(struct kfd_node *dev, const uint32_t *ih_ring_entry) { const struct cik_ih_ring_entry *ihre = -- cgit From c2d2588c702364ff53916ddd97e2b26fd4f4a317 Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Fri, 8 Apr 2022 12:49:48 -0400 Subject: drm/amdkfd: add send exception operation Add a debug operation that allows the debugger to send an exception directly to runtime through a payload address. For memory violations, normal vmfault signals will be applied to notify runtime instead after passing in the saved exception data when a memory violation was raised to the debugger. For runtime exceptions, this will unblock the runtime enable function which will be explained and implemented in a follow up patch.
