[PATCH v2 1/4] drm/amd/display: Drop dm_sw_gfx7_2d_thin_l_vp and dm_sw_gfx7_2d_thin_gl

[Maíra Canal]

As the enum entries dm_sw_gfx7_2d_thin_gl and dm_sw_gfx7_2d_thin_l_vp
are not used on the codebase, drop those entries from enum
dm_swizzle_mode.

[PATCH v2 2/4] drm/amd/display: Remove duplicated CalculateWriteBackDISPCLK

[Maíra Canal]

The functions dml30_CalculateWriteBackDISPCLK and
dml31_CalculateWriteBackDISPCLK are identical. Therefor, to avoid code
duplication, replace dml31_CalculateWriteBackDISPCLK by
dml30_CalculateWriteBackDISPCLK

[PATCH v2 2/4] drm/amd/display: Remove duplicated CalculateWriteBackDISPCLK

[Maíra Canal]

The functions dml30_CalculateWriteBackDISPCLK and
dml31_CalculateWriteBackDISPCLK are identical. Therefor, to avoid code
duplication, replace dml31_CalculateWriteBackDISPCLK by
dml30_CalculateWriteBackDISPCLK

[PATCH v2 3/4] drm/amd/display: Remove parameters from rq_dlg_get_dlg_reg

[Maíra Canal]

Across all DCN's (except DCN32, that has a separate
rq_dlg_get_dlg_reg), the parameters const bool vm_en, const bool
ignore_viewport_pos, and const bool immediate_flip_support are not used
on the function. Therefore, change the rq_dlg_get_dlg_reg signature
by deleting those parameters.

[PATCH v2 3/4] drm/amd/display: Remove parameters from rq_dlg_get_dlg_reg

[Maíra Canal]

Across all DCN's (except DCN32, that has a separate
rq_dlg_get_dlg_reg), the parameters const bool vm_en, const bool
ignore_viewport_pos, and const bool immediate_flip_support are not used
on the function. Therefore, change the rq_dlg_get_dlg_reg signature
by deleting those parameters.

Signed-off-by: Maíra Canal <mairacanal@riseup.net>
---
v1 -> v2:
- Replace "enum" to "enum entries" (André Almeida).

[PATCH v2 4/4] drm/amd/display: Rewrite CalculateWriteBackDISPCLK function

[Maíra Canal]

Based on the dml30_CalculateWriteBackDISPCLK, it separates the
DISPCLK calculations on three variables, making no functional changes, in order
to make it more readable and better express that three values are being compared
on dml_max.

Re: [PATCH v2 3/4] drm/amd/display: Remove parameters from rq_dlg_get_dlg_reg

[Rodrigo Siqueira Jordao]

Hi Maira,

First of all, thanks a lot for this patch. This change is really helpful 
for reducing the stack size. I just have few comments inline.

On 2022-07-21 14:36, Maíra Canal wrote:

hmmm... I'm not sure if I missed something, but you dropped the variable 
pstate_en from the parameter list, but you still have it here. Is this 
correct?

Why are we dropping these logs? It is already hard to debug DML code, 
and reducing the amount of information that we can get does not sound 
good to me.

Thanks

Re: [PATCH v2 3/4] drm/amd/display: Remove parameters from rq_dlg_get_dlg_reg

[Rodrigo Siqueira Jordao]

Hi Maira,

First of all, thanks a lot for this patch. This change is really helpful 
for reducing the stack size. I just have few comments inline.

On 2022-07-21 14:36, Maíra Canal wrote:

hmmm... I'm not sure if I missed something, but you dropped the variable 
pstate_en from the parameter list, but you still have it here. Is this 
correct?

Why are we dropping these logs? It is already hard to debug DML code, 
and reducing the amount of information that we can get does not sound 
good to me.

Thanks

Yep, I missed that. But I remember have compiled the code and deploying
it. So, I went to check it and examine it I found out that the
dml314_rq_dlg_get_dlg_reg is not even used on the codebase. Which can
indicate one of two things:

1. Should exist a dml314_func struct on the dml/display_mode_lib.c with
this function.

2. The dml/dcn314/display_rq_dlg_calc_314 files should be deleted, as
none of its functions are used on the codebase.

I believe you might know which one is the correct option.

The parameters vm_en, ignore_viewport_pos, and immediate_flip_support
are hard-coded into code as `false, false, true` on all calls of the
function rq_dlg_get_dlg_reg (there are only two: on cn20/dcn20_fpu.c and
on dml/dml_wrapper.c). As these parameters are already known and don't
change, I don't believe that they add much value to the debug log as the
log will be always the same.

Moreover, I could argue that they are polluting the debug log, as none
of those parameters are being called anywhere else on the codebase. So,
you already know their value from the beginning, and it is the only time
they will ever appear on the log, as they are not considered parameters
anywhere else.

Yep, I missed that. But I remember have compiled the code and deploying
it. So, I went to check it and examine it I found out that the
dml314_rq_dlg_get_dlg_reg is not even used on the codebase. Which can
indicate one of two things:

1. Should exist a dml314_func struct on the dml/display_mode_lib.c with
this function.

2. The dml/dcn314/display_rq_dlg_calc_314 files should be deleted, as
none of its functions are used on the codebase.

I believe you might know which one is the correct option.

The parameters vm_en, ignore_viewport_pos, and immediate_flip_support
are hard-coded into code as `false, false, true` on all calls of the
function rq_dlg_get_dlg_reg (there are only two: on cn20/dcn20_fpu.c and
on dml/dml_wrapper.c). As these parameters are already known and don't
change, I don't believe that they add much value to the debug log as the
log will be always the same.

Moreover, I could argue that they are polluting the debug log, as none
of those parameters are being called anywhere else on the codebase. So,
you already know their value from the beginning, and it is the only time
they will ever appear on the log, as they are not considered parameters
anywhere else.
