答复: 转发: [PATCH 02/23] drm/amdgpu: add kiq into compiling

[Liu, Monk]

Hi Christian,


the CSA VA update should be correct, we pin it after it allocated per device during init stage, and we map it upon each process creates their vm page tables,


since this CSA is pined, I assume there is no need to validate it prior to submission


please correct me if I missed something


BR Monk

Yeah, agree totally with Monk here.

If you find that you need some KIQ helpers which are independent of the
hardware generation you can put them into amdgpu_kiq.c.

Monk, David or maybe even Michel and Nicolai could you guys take a
closer look at the patches.

I'm currently to busy with private issues, so I just briefly skimmed
over them, but still found some issues.

The VA update stuff seems incorrectly handled to me for example. You
only update the page tables once and then assume that everything stays
as it is.

Regards,
Christian.
