            Bug ID: 185681
           Summary: amdgpu: powerplay initialization failed
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.9.0-rc3-1.gb005706-vanilla
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: rene.linder@lihaso.ch
        Regression: No

dmesg output

Since rc2/rc3 the initialization of the TOPAZ Gpu fails on Startup, Kernel
4.8.4 Works fine.

Didn't have currently a rc1 initialization on my Notebook to Test it.

DMESG Output Attached.

If i go back to where the Powermanagment (smu7_hwmgr.c) where the commit
change:

Since Commit: ab4f06d3adcc5165b13ed2e657050fd1808f319b (agd5f/linux
origin/drm-fixes-4.9
-            iceland_hwmgr_init(hwmgr);
+            topaz_set_asic_special_caps(hwmgr);
+            hwmgr->feature_mask &= ~(PP_SMC_VOLTAGE_CONTROL_MASK |

And the Problem is that it get an empty table back here:
        struct phm_ppt_v1_information *table_info =
                        (struct phm_ppt_v1_information *)hwmgr->pptable;
        struct phm_ppt_v1_clock_voltage_dependency_table *sclk_table = NULL;

        printk("Table info");
        if (table_info == NULL) {
                printk("failed\n");
                return -EINVAL;
        }
        printk("successfull");

--- Comment #6 from René Linder <rene.linder@lihaso.ch> ---
I found some missing / wrong parts, if i look at the handle of PP_TABLE_V0 and
PP_TABLE_V1 Handling there is through the whole code everytime a direct access
to V0 = hwmgr->  V1 = table_info->

And i never found in the V0 source parts any pptable fill... i removed now the
smu7_get_evv_voltage from the V0 and now it seems to work partialy... I think
there is going something forget on the rework of the old explicit iceland code
path.

--- Comment #7 from René Linder <rene.linder@lihaso.ch> ---
https://cgit.freedesktop.org/~agd5f/linux/commit/drivers/gpu/drm/amd/powerplay?h=drm-fixes-4.9&id=025f8bfb84cbcaa78df31ab00d7e3c5f979e9e27

there is the iceland_get_evv_voltage who works ... and the new
smu7_get_evv_voltage uses generally the pptable in the beginning and thats
wrong.

There is a if for the V0 path but to late and wrong:


This must be switched bevore hwmgr->pptable (table_info) is requested.         
  if ((hwmgr->pp_table_version == PP_TABLE_V0)
                || !phm_get_sclk_for_voltage_evv(hwmgr,
Wrong part 2 should be hwmgr and not table_info:                   
table_info->vddc_lookup_table, vv_id, &sclk)) {
                if (phm_cap_enabled(hwmgr->platform_descriptor.platformCaps,
                        PHM_PlatformCaps_ClockStretcher)) {
                    for (j = 1; j < sclk_table->count; j++) {
                        if (sclk_table->entries[j].clk == sclk &&
                                sclk_table->entries[j].cks_enable == 0) {
                            sclk += 5000;
                            break;
                        }
                    }
                }

That has worked :-) Now my graphic card did as it should i think.

Something like this in the dmesg log is still there:

[ powerplay ] VBIOS did not find boot engine clock value                       
 in dependency table. Using Memory DPM level 0!

And glxspheres / glxgears works.

I've applied the patches to the rc3 & rc4 Kernel both worked.
