Subject: [PATCH 405/484] rtw89: 8852c: disable dma during mac init
|
|
|
|
Without this patch, our hardware attempts to perform dma while device
|
|
cpu restarts, and leads to iommu page faults caused by invalid requests.
|
|
Some platforms show warning messages as below:
|
|
rtw89_8852ce 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT
|
|
domain=0x000a address=0x10000000004 flags=0x0030]
