[PATCH 1/4] drm/amdgpu/gfx11: properly reference EOP interrupts for userqs

[Alex Deucher]

Regardless of whether we disable kernel queues, we need
to take an extra reference to the pipe interrupts for
user queues to make sure they stay enabled in case we
disable them for kernel queues.

Re: [PATCH 3/4] drm/sdma6: properly reference trap interrupts for userqs

[Khatri, Sunil]

Same explanation as patch 1 of the series here too. Do we want to depend 
on the disable_kq flag solely to enable/disable sdma trap.
IIUC, we dont want to do it in case of kernel queues at all and only 
needed when using userqueue and that is taken care by using the flag 
disable_kq.

I think doing it this way makes the most sense because you are using
the presence of user queues to determine whether or not to take the
extra references.  We don't really care what the status of kernel
queues are.

Re: [PATCH 1/4] drm/amdgpu/gfx11: properly reference EOP interrupts for userqs

[-- Attachment #1: Type: text/plain, Size: 2238 bytes --]

This is how i see the future of this code and we can do based on it now 
itself.
disable_kq = 0, Use kernel queues.
disable_kq = 1, Use User queues.

In case of kernel queues we should not be even calling 
gfx_v11_0_set_userq_eop_interrupts at all. Instead its better if we add 
a this check "if (adev->userq_funcs[AMDGPU_HW_IP_GFX])" before calling 
the gfx_v11_0_set_userq_eop_interrupts. I am assuming there wont be any 
mixed use of kernel|user queues together. Let me know if you think 
otherwise. Regards Sunil Khatri

I feel existing implementation makes more sense. Using the disable_kq 
flag to avoid get/put completely. Get/put for userqueues only here and 
for kernel anyways we are handling in ring_init.

if (adev->userq_funcs[AMDGPU_HW_IP_GFX]), this if condition will always be valid once we enable it based on the fw version. so this will be an additional loop and get/put when kernel queues are being used.

disable_kq = 0 means allow kernel queues and user queues.  disable_kq
=1 means disable kernel queues.  I think we'd want to allow both at
least on current chips.  I think if we want a general knob for kernel
and user queues, we should do something like:
userq:
-1 auto (whatever we want the default to be per IP)
0 disable user queues (kernel queues only where supported)
1 enable user queues (user queues and kernel queues)
2 enable user queues only (disable kernel queues)

We should only be calling it if user queues are enabled.  I think
there will definitely be mixed user and kernel queues on current
hardware as we ramp up on user queues.

Alex, are you saying we could expect some device where Kernel queues and 
user queues will be working in parallel ? If that is the case i can see 
we need eop reference for both the cases and this change then makes 
perfect sense but,  if its either kernel or user then disable_kq feature 
check looked better in control.

That's the case right now for gfx11 and gfx12 dGPUs.  Even if we did
add an option to disable user queues, everything would still work as
expected with the way things are coded in these patches.  The presence
of the userq function pointers determines whether user queues are
enabled for the IP.  If they are NULL, then we skip the extra
references so the logic works for any combination of user queues and
kernel queues.

Instead its better if we add a this check "if (adev->userq_funcs[AMDGPU_HW_IP_GFX])" before calling the gfx_v11_0_set_userq_eop_interrupts. I am assuming there wont be any mixed use of kernel|user queues together. Let me know if you think otherwise. Regards Sunil Khatri

If that is the case i can see we need eop reference for both the cases and this change then makes perfect sense but,  if its either kernel or user then disable_kq feature check looked better in control.

Fair enough,  we do enable the function pointers based on IP.
