[Why & How]
We use outbox interrupt that allows us to do the AUX via DMUB
Therefore, we need to add some irq source related definition
in the header files;
Also, I added debug flag that allows us to turn it on/off
for testing purpose.

If this is intended to be enabled by default then it shouldn't be a
debug flag. Please either leave the default alone or fully switch over
to DMCUB AUX support for ASIC that support it.
If you don't already have a check from driver to DMCUB firmware to
ensure that the firmware itself supports it you'd need that as well -
users can be running older firmware (like the firmware that originally
released with DCN2.1/DCN3.0 support) and that wouldn't support this feature.
My recommendation:
- Add a command to check for DMUB AUX capability or add bits to the
metadata to indicate that the firmware does support it
- Assume that the DMUB AUX implementation is solid and a complete
replacement for existing AUX support on firmware that does support it
- Add a debug flag like DC_DISABLE_DMUB_AUX for optionally debugging
issues if they arise

This technically isn't on DCN_1_0 but I guess we've been using this file
for all the DCNs.
I do wish this was labeled DCN_2_1 instead to make it more explicit but
I guess this is fine for now.

My problem with still leaving this as DC_ENABLE_DMUB_AUX is we shouldn't
require the user to have to flip this on by default later. I think I'd
prefer this still as a DISABLE option if we want to leave it for users
to debug any potential issues.
If there's no value in having end users debug issues by setting this bit
then we should keep it as a dc->debug default in DCN resource.

Hi Nicholas,
Does this completion need to be on the amdgpu device itself?
I would prefer if we keep this as needed within DM itself if possible.
=> do you mean move it to amdgpu_display_manager in amdgpu_dm.h as global variable?

Does this completion need to be on the amdgpu device itself?
I would prefer if we keep this as needed within DM itself if possible.

My problem with still leaving this as DC_ENABLE_DMUB_AUX is we shouldn't require the user to have to flip this on by default later. I think I'd prefer this still as a DISABLE option if we want to leave it for users to debug any potential issues.
If there's no value in having end users debug issues by setting this bit then we should keep it as a dc->debug default in DCN resource.

There's a amdgpu_display_manager per device, but yes, it should be
contained in there if possible since it's display code.

Don't modify the default debug mask and leave it alone. We can still
have DC_DISABLE_DMUB_AUX = 0x10 as a user debug option if they have
firmware that supports this.
Flag or not, we need a mechanism from driver to firmware to query
whether the firmware supports it in the first place. It's not sufficient
to fully control this feature with just a debug flag, there needs to be
a cap check regardless with the firmware for support.
Older firmware won't implement this check and therefore won't enable the
feature.
Newer (or test) firmware could enable this feature and report back to
driver that it does support it.
Driver can then decide to enable this based on
dc->debug.dmub_aux_support or something similar to that - it can be
false or ASIC that we won't be supporting this on, but for ASIC that we
do we can leave it off by default until it's production ready.
For developer testing we can hardcode the flag = true, I think the DC
debug flags here in AMDGPU base driver only have value if we want
general end user or validation to use this to debug potential issues.

[AMD Official Use Only - Internal Distribution Only]
Hi Nicholas,
Let me summarize the suggestion. Please correct me if I misunderstood.
1. for dmub_aux_transfer_done, move it to amdgpu_display_manager in amdgpu_dm.h instead of amdgpu.h
2. Remove DC_ENABLE_DMUB_AUX from amd_shared.h at current stage since we don't have a mechanism to check the firmware yet. We just hardcore this flag when testing.
3. Keep the irq source change in irqsrcs_dcn_1_0.h at current stage since we don't have irqsrc_dcn_2_1.h
=> So I will just keep the change in irqsrcs_dcn_1_0.h and dmub_outbox_irq in amdgpu.h?
Thanks!
Best Regards,
Jude

[Why & How]
We use outbox interrupt that allows us to do the AUX via DMUB
Therefore, we need to add some irq source related definition
in the header files;
