But during debug, I found amdgpu_device_doorbell_init uses adev->doorbell_index.max_assignment which is initialized in *_doorbell_index_init. So I have to call *_doorbell_index_init before amdgpu_device_doorbell_init. *_set_ip_blocks() is too late. In a later version, I moved calling of *_doorbell_index_init to the top of amdgpu_device_doorbell_init. thanks, Oak -----Original Message----- From: Alex Deucher <alexdeucher@gmail.com> Sent: Sunday, November 25, 2018 1:43 PM To: Zeng, Oak <Oak.Zeng@amd.com> Subject: Fwd: [PATCH 5/7] drm/amdgpu: Call doorbell index init on device initialization ---------- Forwarded message --------- From: Alex Deucher <alexdeucher@gmail.com> Date: Wed, Nov 21, 2018 at 11:21 AM Subject: Re: [PATCH 5/7] drm/amdgpu: Call doorbell index init on device initialization To: <ozeng@amd.com> Cc: amd-gfx list <amd-gfx@lists.freedesktop.org>, Oak Zeng <Oak.Zeng@amd.com> On Wed, Nov 21, 2018 at 10:52 AM Oak Zeng <ozeng@amd.com> wrote: > > Change-Id: I2f004bbbe2565035460686f4fc16e86b77a2a9b5 > Signed-off-by: Oak Zeng <ozeng@amd.com> > Suggested-by: Felix Kuehling <Felix.Kuehling@amd.com> > Suggested-by: Alex Deucher <alexander.deucher@amd.com> I think it would be cleaner to add this to the *_set_ip_blocks() functions in cik.c, vi.c, and soc15.c so it aligns with the *_reg_base_init() calls.
