Re: 回复: 回复: [RFC PATCH 1/2] drm/amdgpu: Fix memory corruption due to swapout and swapin

I just sent out patch below yesterday. swapping unpopulated bo is useless indeed. [RFC PATCH 2/2] drm/ttm: skip swapout when ttm has no backend page.

[AMD Official Use Only] yes, we really dont swapout SG BOs. The problems is that before we validate a userptr BO, we create this BO in CPU domain by default. So this BO has chance to swapout. we set flag TTM_PAGE_FLAG_SG on userptr BO in popluate() which is too late. I have not try to revert Chr
