[HOW] remove covert_10k_to_mhz in smu interface this fixes corruption issue with 4k @60 display and stutter mode enable Signed-off-by: hersen wu <hersenxs.wu@xxxxxxx> --- .../gpu/drm/amd/powerplay/hwmgr/smu10_hwmgr.c | 17 ++++++----------- 1 file changed, 6 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/amd/powerplay/hwmgr/smu10_hwmgr.c b/drivers/gpu/drm/amd/powerplay/hwmgr/smu10_hwmgr.c index f32e3d0aaea6..078613348e78 100644 --- a/drivers/gpu/drm/amd/powerplay/hwmgr/smu10_hwmgr.c +++ b/drivers/gpu/drm/amd/powerplay/hwmgr/smu10_hwmgr.c @@ -204,18 +204,13 @@ static int smu10_set_clock_limit(struct pp_hwmgr *hwmgr, const void *input) return 0; } -static inline uint32_t convert_10k_to_mhz(uint32_t clock) -{ - return (clock + 99) / 100; -} - static int smu10_set_min_deep_sleep_dcefclk(struct pp_hwmgr *hwmgr, uint32_t clock) { struct smu10_hwmgr *smu10_data = (struct smu10_hwmgr *)(hwmgr->backend); if (smu10_data->need_min_deep_sleep_dcefclk && - smu10_data->deep_sleep_dcefclk != convert_10k_to_mhz(clock)) { - smu10_data->deep_sleep_dcefclk = convert_10k_to_mhz(clock); + smu10_data->deep_sleep_dcefclk != clock) { + smu10_data->deep_sleep_dcefclk = clock; smum_send_msg_to_smc_with_parameter(hwmgr, PPSMC_MSG_SetMinDeepSleepDcefclk, smu10_data->deep_sleep_dcefclk); @@ -228,8 +223,8 @@ static int smu10_set_hard_min_dcefclk_by_freq(struct pp_hwmgr *hwmgr, uint32_t c struct smu10_hwmgr *smu10_data = (struct smu10_hwmgr *)(hwmgr->backend); if (smu10_data->dcf_actual_hard_min_freq && - smu10_data->dcf_actual_hard_min_freq != convert_10k_to_mhz(clock)) { - smu10_data->dcf_actual_hard_min_freq = convert_10k_to_mhz(clock); + smu10_data->dcf_actual_hard_min_freq != clock) { + smu10_data->dcf_actual_hard_min_freq = clock; smum_send_msg_to_smc_with_parameter(hwmgr, PPSMC_MSG_SetHardMinDcefclkByFreq, smu10_data->dcf_actual_hard_min_freq); @@ -242,8 +237,8 @@ static int smu10_set_hard_min_fclk_by_freq(struct pp_hwmgr *hwmgr, uint32_t cloc struct smu10_hwmgr *smu10_data = (struct smu10_hwmgr *)(hwmgr->backend); if (smu10_data->f_actual_hard_min_freq && - smu10_data->f_actual_hard_min_freq != convert_10k_to_mhz(clock)) { - smu10_data->f_actual_hard_min_freq = convert_10k_to_mhz(clock); + smu10_data->f_actual_hard_min_freq != clock) { + smu10_data->f_actual_hard_min_freq = clock; smum_send_msg_to_smc_with_parameter(hwmgr, PPSMC_MSG_SetHardMinFclkByFreq, smu10_data->f_actual_hard_min_freq); -- 2.17.1 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
