--- Comment #21 from Janpieter Sollie ---
Created attachment 145764
--> https://bugs.freedesktop.org/attachment.cgi?id=145764=edit
dmesg of PPLIB error
still present on linux 5.3, with the following exceptions:
- the values in mV seem to be initialized,
- DRM does not complain about 'Cannot find any crtc or sizes' after GPU adding
- DRM: construct error is gone
So it's going the good way, I guess ...
I investigated the source around dcn_bw_update_from_pplib
And I saw the following code in gpu/drm/amd/display/dc/calcs/dcn_calcs.c
bool res;
/* TODO: This is not the proper way to obtain
fabric_and_dram_bandwidth, should be min(fclk, memclk) */
res = dm_pp_get_clock_levels_by_type_with_voltage(
ctx, DM_PP_CLOCK_TYPE_FCLK, );
kernel_fpu_begin();
if (res)
res = verify_clock_values();
if (res) {
//unimportant, left out
} else
BREAK_TO_DEBUGGER();
=
which probably explains what happens: fclks gets a number of clock values from
dm_pp_get_clock_levels_by_type_with_voltage, setting res to true.
It tries to validate the clock values then, which fails because of the invalid
numbers
After that, it breaks to debugger.
Is it possible the vega11 needs more time to initialize its clock limits?

--- Comment #16 from Paul Menzel ---
Could some AMD developer please comment, on how to fix this? Tables(?)
containing “0 kHz” are apparently shipped by vendors, so what to do?
```
static bool verify_clock_values(struct dm_pp_clock_levels_with_voltage *clks)
{
int i;
if (clks->num_levels == 0)
return false;
for (i = 0; i < clks->num_levels; i++)
/* Ensure that the result is sane */
if (clks->data[i].clocks_in_khz == 0)
return false;
return true;
}
```
Should commit 00893681a0ff4 (drm/amd/display: Reject PPLib clock values if they
are invalid) [1] be reverted? Andrew, Tony, Harry?
> drm/amd/display: Reject PPLib clock values if they are invalid
>
> We should be sticking with the default clock values if the values
> obtained from PPLib are bogus.

PS: AMDGPU’s commit messages are too terse, and should be more elaborate.

--- Comment #1 from Paul Menzel ---
In today’s drm-tip this is:
[ 20.149515] WARNING: CPU: 0 PID: 347 at
drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calcs.c:1372
dcn_bw_update_from_pplib+0x16b/0x280 [amdgpu]
It looks like this is `BREAK_TO_DEBUGGER()` [1], which is defined as `#define
BREAK_TO_DEBUGGER() ASSERT(0)`.
```
/* TODO: This is not the proper way to obtain
fabric_and_dram_bandwidth, should be min(fclk, memclk) */
res = dm_pp_get_clock_levels_by_type_with_voltage(
ctx, DM_PP_CLOCK_TYPE_FCLK, );
if (res)
res = verify_clock_values();
if (res) {
ASSERT(fclks.num_levels >= 3);
dc->dcn_soc->fabric_and_dram_bandwidth_vmin0p65 = 32 *
(fclks.data[0].clocks_in_khz / 1000.0) / 1000.0;
dc->dcn_soc->fabric_and_dram_bandwidth_vmid0p72 =
dc->dcn_soc->number_of_channels *
(fclks.data[fclks.num_levels -
(fclks.num_levels > 2 ? 3 : 2)].clocks_in_khz / 1000.0)
* ddr4_dram_factor_single_Channel / 1000.0;
dc->dcn_soc->fabric_and_dram_bandwidth_vnom0p8 =
dc->dcn_soc->number_of_channels *
(fclks.data[fclks.num_levels - 2].clocks_in_khz
/ 1000.0)
* ddr4_dram_factor_single_Channel / 1000.0;
dc->dcn_soc->fabric_and_dram_bandwidth_vmax0p9 =
dc->dcn_soc->number_of_channels *
(fclks.data[fclks.num_levels - 1].clocks_in_khz
/ 1000.0)
* ddr4_dram_factor_single_Channel / 1000.0;
} else
BREAK_TO_DEBUGGER();
```
So, either `dm_pp_get_clock_levels_by_type_with_voltage()` or
`verify_clock_values()` returns 0.
