Hi Ritesh,
Dan,
I can reproduce the issue on my system running Chimera Linux with 4K
page size.
System details:
- Machine: RaptorCS Blackbird (POWER9, PowerNV)
- GPU: Sapphire Pulse Radeon RX 5500 XT (Navi 14)
- Kernel: 7.0-rc1
The failure is identical, ending in:
> amdgpu ... (-12) failed to allocate kernel bo
> amdgpu ... amdgpu_device_wb_init failed -12
> amdgpu ... Fatal error during GPU init
I also see:
> iommu: 64-bit OK but direct DMA is limited by 0
> dma_iommu_get_required_mask: returning bypass mask 0xfffffffffffffff
This is with 4K pages, so it does not seem to be limited to 64K page
configurations.
Regards,
Karl
