Otherwise the first several seconds may be silent in audio playback. The relationship of Maud and Naud is expressed in the following equation: Maud/Naud = 512 * fs / f_LS_Clk Please refer VESA DisplayPort Standard spec for details. v2 by Jani: - organize Maud/Naud table according to DP 1.4 spec - add 64k and 128k audio rates - update HSW_AUD_M_CTS_ENABLE register when Maud not found - remove extra checks for port clock - simplify Maud/Naud lookup - reset patch author back to Libin Cc: "Zhang, Keqiao" <keqiao.zhang@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: "Lin, Mengdong" <mengdong.lin@intel.com> Signed-off-by: Libin Yang <libin.yang@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> --- drivers/gpu/drm/i915/i915_reg.h | 7 +++ drivers/gpu/drm/i915/intel_audio.c | 93 +++++++++++++++++++++++++++++++++++++- 2 files changed, 99 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index bdc7b3591e1c..542e570b3578 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -7370,6 +7370,13 @@ enum { #define _HSW_AUD_MISC_CTRL_B 0x65110 #define HSW_AUD_MISC_CTRL(pipe) _MMIO_PIPE(pipe, _HSW_AUD_MISC_CTRL_A, _HSW_AUD_MISC_CTRL_B) +#define _HSW_AUD_M_CTS_ENABLE_A 0x65028 +#define _HSW_AUD_M_CTS_ENABLE_B 0x65128 +#define HSW_AUD_M_CTS_ENABLE(pipe) _MMIO_PIPE(pipe, _HSW_AUD_M_CTS_ENABLE_A, _HSW_AUD_M_CTS_ENABLE_B) +#define AUD_M_CTS_M_VALUE_INDEX (1 << 21) +#define AUD_M_CTS_M_PROG_ENABLE (1 << 20) +#define AUD_CONFIG_M_MASK 0xfffff + #define _HSW_AUD_DIP_ELD_CTRL_ST_A 0x650b4 #define _HSW_AUD_DIP_ELD_CTRL_ST_B 0x651b4 #define HSW_AUD_DIP_ELD_CTRL(pipe) _MMIO_PIPE(pipe, _HSW_AUD_DIP_ELD_CTRL_ST_A, _HSW_AUD_DIP_ELD_CTRL_ST_B) diff --git a/drivers/gpu/drm/i915/intel_audio.c b/drivers/gpu/drm/i915/intel_audio.c index 1a5c21209446..813fd74d9c8d 100644 --- a/drivers/gpu/drm/i915/intel_audio.c +++ b/drivers/gpu/drm/i915/intel_audio.c @@ -57,6 +57,63 @@ * struct &i915_audio_component_audio_ops @audio_ops is called from i915 driver. */ +/* DP N/M table */ +#define LC_540M 540000 +#define LC_270M 270000 +#define LC_162M 162000 + +struct dp_aud_n_m { + int sample_rate; + int clock; + u16 m; + u16 n; +}; + +/* Values according to DP 1.4 Table 2-104 */ +static const struct dp_aud_n_m dp_aud_n_m[] = { + { 32000, LC_162M, 1024, 10125 }, + { 44100, LC_162M, 784, 5625 }, + { 48000, LC_162M, 512, 3375 }, + { 64000, LC_162M, 2048, 10125 }, + { 88200, LC_162M, 1568, 5625 }, + { 96000, LC_162M, 1024, 3375 }, + { 128000, LC_162M, 4096, 10125 }, + { 176400, LC_162M, 3136, 5625 }, + { 192000, LC_162M, 2048, 3375 }, + { 32000, LC_270M, 1024, 16875 }, + { 44100, LC_270M, 784, 9375 }, + { 48000, LC_270M, 512, 5625 }, + { 64000, LC_270M, 2048, 16875 }, + { 88200, LC_270M, 1568, 9375 }, + { 96000, LC_270M, 1024, 5625 }, + { 128000, LC_270M, 4096, 16875 }, + { 176400, LC_270M, 3136, 9375 }, + { 192000, LC_270M, 2048, 5625 }, + { 32000, LC_540M, 1024, 33750 }, + { 44100, LC_540M, 784, 18750 }, + { 48000, LC_540M, 512, 11250 }, + { 64000, LC_540M, 2048, 33750 }, + { 88200, LC_540M, 1568, 18750 }, + { 96000, LC_540M, 1024, 11250 }, + { 128000, LC_540M, 4096, 33750 }, + { 176400, LC_540M, 3136, 18750 }, + { 192000, LC_540M, 2048, 11250 }, +}; + +static const struct dp_aud_n_m * +audio_config_dp_get_n_m(struct intel_crtc *intel_crtc, int rate) +{ + int i; + + for (i = 0; i < ARRAY_SIZE(dp_aud_n_m); i++) { + if (rate == dp_aud_n_m[i].sample_rate && + intel_crtc->config->port_clock == dp_aud_n_m[i].clock) + return &dp_aud_n_m[i]; + } + + return NULL; +} + static const struct { int clock; u32 config; @@ -225,16 +282,43 @@ hsw_dp_audio_config_update(struct intel_crtc *intel_crtc, enum port port, const struct drm_display_mode *adjusted_mode) { struct drm_i915_private *dev_priv = to_i915(intel_crtc->base.dev); + struct i915_audio_component *acomp = dev_priv->audio_component; + int rate = acomp ?
