For SRIOV, since the CP_INT_CNTL_RING0 is programed on host side.
The Guest should not program CP_INT_CNTL_RING0 again.

This needs to be below the stack variable declarations or you'll get a warning.

Fixed it as Monk and Hawking suggestion. Now it only has one checking in function gfx_v10_0_enable_gui_idle_interrupt.
BTW, I update the commit, but it send out an another email.
Thanks,

Gavin
Looks the only place you need to change is the part of avoid touching "CP_INT_CNTL_RING0" which is handled by GIM now
Others looks not needed at all

Subject: RE: [PATCH] drm/amd/amdgpu: Fix the CGCG setting is overwritten for SRIOV.
[AMD Public Use]
Can we leverage existing CG flags to control this rather than add amdgpu_sriov_vf(adev) check everywhere?
If GC CG feature is programmed by host. We can just mask out the following flags for guest driver case (amdgpu_sriov_vf(adev)).
AMD_CG_SUPPORT_GFX_MGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_CGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_3D_CGCG |
AMD_CG_SUPPORT_GFX_3D_CGLS
There are too many amdgpu_sriov_vf(adev) Check in amdgpu driver, which actually add unnecessary sustaining effort.

Hawking

Subject: [PATCH] drm/amd/amdgpu: Fix the CGCG setting is overwritten for SRIOV.
For SRIOV, since the CGCG is set on host side. The Guest should not program CGCG again.
The patch ignores setting CGCG for SRIOV.

[Guchun]This coding style is not correct. You should put the check after the declare of 'u32 tmp'.
Maybe it's better to split below line to declare and execution parts respectively.

Looks the only place you need to change is the part of avoid touching "CP_INT_CNTL_RING0" which is handled by GIM now
Others looks not needed at all

Subject: RE: [PATCH] drm/amd/amdgpu: Fix the CGCG setting is overwritten for SRIOV.
[AMD Public Use]
Can we leverage existing CG flags to control this rather than add amdgpu_sriov_vf(adev) check everywhere?
If GC CG feature is programmed by host. We can just mask out the following flags for guest driver case (amdgpu_sriov_vf(adev)).
AMD_CG_SUPPORT_GFX_MGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_CGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_3D_CGCG |
AMD_CG_SUPPORT_GFX_3D_CGLS
There are too many amdgpu_sriov_vf(adev) Check in amdgpu driver, which actually add unnecessary sustaining effort.

Hawking

For SRIOV, since the CGCG is set on host side. The Guest should not program CGCG again.
The patch ignores setting CGCG for SRIOV.

Gavin
Looks the only place you need to change is the part of avoid touching "CP_INT_CNTL_RING0" which is handled by GIM now
Others looks not needed at all

Subject: RE: [PATCH] drm/amd/amdgpu: Fix the CGCG setting is overwritten for SRIOV.
[AMD Public Use]
Can we leverage existing CG flags to control this rather than add amdgpu_sriov_vf(adev) check everywhere?
If GC CG feature is programmed by host. We can just mask out the following flags for guest driver case (amdgpu_sriov_vf(adev)).
AMD_CG_SUPPORT_GFX_MGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_CGCG |
AMD_CG_SUPPORT_GFX_CGLS |
AMD_CG_SUPPORT_GFX_3D_CGCG |
AMD_CG_SUPPORT_GFX_3D_CGLS
There are too many amdgpu_sriov_vf(adev) Check in amdgpu driver, which actually add unnecessary sustaining effort.

Hawking

For SRIOV, since the CGCG is set on host side. The Guest should not program CGCG again.
The patch ignores setting CGCG for SRIOV.

Subject: [PATCH] drm/amd/amdgpu: Fix the CGCG setting is overwritten for SRIOV.
For SRIOV, since the CGCG is set on host side. The Guest should not program CGCG again.
The patch ignores setting CGCG for SRIOV.

[Guchun]This coding style is not correct. You should put the check after the declare of 'u32 tmp'.
Maybe it's better to split below line to declare and execution parts respectively.
