From d435c1ed56b9f9347189924395588cfdf7489af5 Mon Sep 17 00:00:00 2001 From: Lang Yu Date: Mon, 24 Jan 2022 14:25:34 +0800 Subject: drm/amd/pm: add get_dpm_ultimate_freq function for cyan skillfish Some clients(e.g., kfd) query sclk/mclk through this function. As cyan skillfish doesn't support dpm, for sclk, set min/max to CYAN_SKILLFISH_SCLK_MIN/CYAN_SKILLFISH_SCLK_MAX(to maintain the existing logic).For others, set both min and max to current value. Before this patch: # /opt/rocm/opencl/bin/clinfo Max clock frequency: 0Mhz After this patch: # /opt/rocm/opencl/bin/clinfo Max clock frequency: 2000Mhz v2: - Maintain the existing min/max sclk logic.(Lijo) v3: - Avoid fetching metrics table twice.(Lijo) Signed-off-by: Lang Yu Reviewed-by: Lijo Lazar Reviewed-by: Huang Rui Signed-off-by: Alex Deucher --- .../drm/amd/pm/swsmu/smu11/cyan_skillfish_ppt.c | 31 ++++++++++++++++++++++ 1 file changed, 31 insertions(+) (limited to 'drivers/gpu/drm/amd/pm/swsmu') diff --git a/drivers/gpu/drm/amd/pm/swsmu/smu11/cyan_skillfish_ppt.c b/drivers/gpu/drm/amd/pm/swsmu/smu11/cyan_skillfish_ppt.c index 2acd7470431e..d743984b68a2 100644 --- a/drivers/gpu/drm/amd/pm/swsmu/smu11/cyan_skillfish_ppt.c +++ b/drivers/gpu/drm/amd/pm/swsmu/smu11/cyan_skillfish_ppt.c @@ -542,6 +542,36 @@ static int cyan_skillfish_od_edit_dpm_table(struct smu_context *smu, return ret; } +static int cyan_skillfish_get_dpm_ultimate_freq(struct smu_context *smu, + enum smu_clk_type clk_type, + uint32_t *min, + uint32_t *max) +{ + int ret = 0; + uint32_t low, high; + + switch (clk_type) { + case SMU_GFXCLK: + case SMU_SCLK: + low = CYAN_SKILLFISH_SCLK_MIN; + high = CYAN_SKILLFISH_SCLK_MAX; + break; + default: + ret = cyan_skillfish_get_current_clk_freq(smu, clk_type, &low); + if (ret) + return ret; + high = low; + break; + } + + if (min) + *min = low; + if (max) + *max = high; + + return 0; +} + static const struct pptable_funcs cyan_skillfish_ppt_funcs = { .check_fw_status = smu_v11_0_check_fw_status, @@ -555,6 +585,7 @@ static const struct pptable_funcs cyan_skillfish_ppt_funcs = { .is_dpm_running = cyan_skillfish_is_dpm_running, .get_gpu_metrics = cyan_skillfish_get_gpu_metrics, .od_edit_dpm_table = cyan_skillfish_od_edit_dpm_table, + .get_dpm_ultimate_freq = cyan_skillfish_get_dpm_ultimate_freq, .register_irq_handler = smu_v11_0_register_irq_handler, .notify_memory_pool_location = smu_v11_0_notify_memory_pool_location, .send_smc_msg_with_param = smu_cmn_send_smc_msg_with_param, -- cgit
