Hi Christian,
The resubmitted job in function amdgpu_ib_preempt_job_recovery returns the same
hw fence because of this commit:
static void amdgpu_ib_preempt_job_recovery(struct drm_gpu_scheduler *sched)
{
struct drm_sched_job *s_job;

Dma_fence_signal returning non-zero indicates
that the fence is signaled and put somewhere else.
Skip dma_fence_put to make the fence refcount correct.
Well quite a big NAK on this.

Set register to enable mcbp according to amdgpu_mcbp.
Add sdma preempt_ib function used for debugfs test.

1. Use unmap_queue package to trigger preemption on gfx9
Add trailing fence to track the preemption done.
2. Modify emit_ce_meta emit_de_meta functions
for the resumed ibs.

Usually that should be the other way around, libdrm aligns to the kernel.
Why was that modification committed to libdrm first? There are usually
plenty of warnings before we can do that.

As a compromise we are considering a change that restores the old allocation
