[ Upstream commit 04e0481526e30ab8c7e7580033d2f88b7ef2da3f ]
When `nouveau_dmem_copy_one` is called, the following error occurs:
[272146.675156] nouveau 0000:06:00.0: fifo: PBDMA9: 00000004 [HCE_PRIV] ch 1 00000300 00003386
This indicates that a copy push command triggered a Host Copy Engine Privileged error on channel 1 (Copy Engine channel). To address this issue, modify the Copy Engine channel to allow privileged push commands
