From a63e6b83c21424b6ecfca7ecbf605f9af75ae296 Mon Sep 17 00:00:00 2001 From: Darren Powell Date: Mon, 7 Mar 2022 21:40:35 -0500 Subject: [PATCH] amdgpu/pm: Implement emit_clk_levels for vega10 (v1) - implement emit_clk_levels for vega10, based on print_clk_levels, but using sysfs_emit rather than sprintf - modify local int vars to use uint32_t to match arg type of called functions - add return of error codes - refactor OD_XXX cases to return early with -EOPNOTSUPP if !(hwmgr->od_enabled) Signed-off-by: Darren Powell Reviewed-by: Evan Quan Signed-off-by: Alex Deucher --- .../gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c | 147 +++++++++++++++++++++ 1 file changed, 147 insertions(+) diff --git a/drivers/gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c b/drivers/gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c index 37324f2..99bfe5e 100644 --- a/drivers/gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c +++ b/drivers/gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c @@ -4625,6 +4625,152 @@ static int vega10_get_current_pcie_link_speed_level(struct pp_hwmgr *hwmgr) >> PSWUSP0_PCIE_LC_SPEED_CNTL__LC_CURRENT_DATA_RATE__SHIFT; } +static int vega10_emit_clock_levels(struct pp_hwmgr *hwmgr, + enum pp_clock_type type, char *buf, int *offset) +{ + struct vega10_hwmgr *data = hwmgr->backend; + struct vega10_single_dpm_table *sclk_table = &(data->dpm_table.gfx_table); + struct vega10_single_dpm_table *mclk_table = &(data->dpm_table.mem_table); + struct vega10_single_dpm_table *soc_table = &(data->dpm_table.soc_table); + struct vega10_single_dpm_table *dcef_table = &(data->dpm_table.dcef_table); + struct vega10_odn_clock_voltage_dependency_table *podn_vdd_dep = NULL; + uint32_t gen_speed, lane_width, current_gen_speed, current_lane_width; + PPTable_t *pptable = &(data->smc_state_table.pp_table); + + uint32_t i, now, count = 0; + int ret = 0; + + switch (type) { + case PP_SCLK: + if (data->registry_data.sclk_dpm_key_disabled) + return -EOPNOTSUPP; + + ret = smum_send_msg_to_smc(hwmgr, PPSMC_MSG_GetCurrentGfxclkIndex, &now); + if (unlikely(ret != 0)) + return ret; + + if (hwmgr->pp_one_vf && + (hwmgr->dpm_level == AMD_DPM_FORCED_LEVEL_PROFILE_PEAK)) + count = 5; + else + count = sclk_table->count; + for (i = 0; i < count; i++) + *offset += sysfs_emit_at(buf, *offset, "%d: %uMhz %s\n", + i, sclk_table->dpm_levels[i].value / 100, + (i == now) ?
