+static int xgpu_vi_mailbox_rcv_irq(struct amdgpu_device *adev,
+ struct amdgpu_irq_src *source,
+ struct amdgpu_iv_entry *entry)
+{
+ int r;
+
+ adev->virt.caps &= ~AMDGPU_SRIOV_CAPS_RUNTIME;
+ r = xgpu_vi_mailbox_rcv_msg(adev, IDH_FLR_NOTIFICATION);
+ /* do nothing for other msg */
+ if (r)
+ return 0;
+
+ /* TODO: need to save gfx states */
+ schedule_delayed_work(&adev->virt.flr_work,
+ msecs_to_jiffies(VI_MAILBOX_RESET_TIME));
+
+ return 0;
+}
[ML] we should be able to receive at least two type of IRQ from mailbox:
One is FLR_NOTIFICATION and another one is IDH_FLR_NOTIFICATION_CMPL,
The previous one means GIM told us GIM will start do FLR
The later one means GIM told us GIM already finished FLR and from that on Guest driver can do re-initialize .
You only handle the first IRQ, and dispatch a delay_work to monitor event of IDH_FLR_NOTIFICATION_CMPL,
I suspect that correct scheme may be you handle both of those two type of IRQ , please check with @Frank and me on the detail tomorrow .
