In this case, driver can support underclocking. -and set od max memory clock to the value in highest memory dpm level. -So the od max memory clock should be less than highest soc clock. -and driver should not change the soc clock. - -caused by commit ca57b9b0a156 -("drm/amd/pp: Allow underclocking when od table is empty in vbios") - -Reviewed-by: Evan Quan <evan.quan@amd.com> -Signed-off-by: Rex Zhu <Rex.Zhu@amd.com> ---- - drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c | 9 +++++++-- - 1 file changed, 7 insertions(+), 2 deletions(-) - -diff --git a/drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c b/drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c -index 896c10b..f49e0d3 100644 ---- a/drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c -+++ b/drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c -@@ -321,8 +321,12 @@ static int vega10_odn_initial_default_setting(struct pp_hwmgr *hwmgr) - odn_table->min_vddc = dep_table[0]->entries[0].vddc; - - i = od_table[2]->count - 1; -- od_table[2]->entries[i].clk = hwmgr->platform_descriptor.overdriveLimit.memoryClock; -- od_table[2]->entries[i].vddc = odn_table->max_vddc; -+ od_table[2]->entries[i].clk = hwmgr->platform_descriptor.overdriveLimit.memoryClock > od_table[2]->entries[i].clk ? -+ hwmgr->platform_descriptor.overdriveLimit.memoryClock : -+ od_table[2]->entries[i].clk; -+ od_table[2]->entries[i].vddc = odn_table->max_vddc > od_table[2]->entries[i].vddc ? -+ odn_table->max_vddc : -+ od_table[2]->entries[i].vddc; - - return 0; - } -@@ -1325,6 +1329,7 @@ static int vega10_setup_default_dpm_tables(struct pp_hwmgr *hwmgr) - if (hwmgr->platform_descriptor.overdriveLimit.memoryClock == 0) - hwmgr->platform_descriptor.overdriveLimit.memoryClock = - dpm_table->dpm_levels[dpm_table->count-1].value; -+ - vega10_init_dpm_state(&(dpm_table->dpm_state)); - - data->dpm_table.eclk_table.count = 0; --- -2.7.4 - |
