This\nredundancy meant the same information was represented twice, with no\ntype-level guarantee that they stayed in sync.\n\nReplace these fields with a single AudioFormat field, and add helper\nfunctions to extract the derived properties when needed:\n- audio_format_bits()\n- audio_format_is_signed()\n- audio_format_is_float()\n\nThis improves type safety by making AudioFormat the single source of\ntruth, eliminating the possibility of inconsistent state between the\nformat enum and its derived boolean/integer representations.\n\nSigned-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>\nReviewed-by: Akihiko Odaki <odaki@rsg.ci.i.u-tokyo.ac.jp>\nReviewed-by: Mark Cave-Ayland <mark.caveayland@nutanix.com>\n---\n audio/audio_int.h | 4 +-\n audio/audio_template.h | 12 +--\n include/qemu/audio.h | 49 +++++++++++\n audio/audio-mixeng-be.c | 218 ++++++++++++++----------------------------------\n audio/dbusaudio.c | 12 +--\n audio/coreaudio.m | 2 +-\n 6 files changed, 126 insertions(+), 171 deletions(-)", "diff": "diff --git a/audio/audio_int.h b/audio/audio_int.h\nindex 5334c4baad2..dd5f2220d75 100644\n--- a/audio/audio_int.h\n+++ b/audio/audio_int.h\n@@ -45,9 +45,7 @@ struct audio_callback {\n };\n \n struct audio_pcm_info {\n- int bits;\n- bool is_signed;\n- bool is_float;\n+ AudioFormat af;\n int freq;\n int nchannels;\n int bytes_per_frame;\ndiff --git a/audio/audio_template.h b/audio/audio_template.h\nindex 08d60422589..3da91a4782c 100644\n--- a/audio/audio_template.h\n+++ b/audio/audio_template.h\n@@ -173,7 +173,7 @@ static int glue (audio_pcm_sw_init_, TYPE) (\n sw->empty = true;\n #endif\n \n- if (sw->info.is_float) {\n+ if (audio_format_is_float(hw->info.af)) {\n #ifdef DAC\n sw->conv = mixeng_conv_float[sw->info.nchannels == 2]\n [sw->info.swap_endianness];\n@@ -188,9 +188,9 @@ static int glue (audio_pcm_sw_init_, TYPE) (\n sw->clip = mixeng_clip\n #endif\n [sw->info.nchannels == 2]\n- [sw->info.is_signed]\n+ [audio_format_is_signed(hw->info.af)]\n [sw->info.swap_endianness]\n- [audio_bits_to_index(sw->info.bits)];\n+ [audio_format_to_index(hw->info.af)];\n }\n \n sw->name = g_strdup (name);\n@@ -300,7 +300,7 @@ static HW *glue(audio_pcm_hw_add_new_, TYPE)(AudioMixengBackend *s,\n goto err1;\n }\n \n- if (hw->info.is_float) {\n+ if (audio_format_is_float(hw->info.af)) {\n #ifdef DAC\n hw->clip = mixeng_clip_float[hw->info.nchannels == 2]\n [hw->info.swap_endianness];\n@@ -315,9 +315,9 @@ static HW *glue(audio_pcm_hw_add_new_, TYPE)(AudioMixengBackend *s,\n hw->conv = mixeng_conv\n #endif\n [hw->info.nchannels == 2]\n- [hw->info.is_signed]\n+ [audio_format_is_signed(hw->info.af)]\n [hw->info.swap_endianness]\n- [audio_bits_to_index(hw->info.bits)];\n+ [audio_format_to_index(hw->info.af)];\n }\n \n glue(audio_pcm_hw_alloc_resources_, TYPE)(hw);\ndiff --git a/include/qemu/audio.h b/include/qemu/audio.h\nindex b6b6ee9b560..9e4566d60aa 100644\n--- a/include/qemu/audio.h\n+++ b/include/qemu/audio.h\n@@ -185,6 +185,55 @@ bool audio_be_set_dbus_server(AudioBackend *be,\n \n const char *audio_application_name(void);\n \n+static inline int audio_format_bits(AudioFormat fmt)\n+{\n+ switch (fmt) {\n+ case AUDIO_FORMAT_S8:\n+ case AUDIO_FORMAT_U8:\n+ return 8;\n+\n+ case AUDIO_FORMAT_S16:\n+ case AUDIO_FORMAT_U16:\n+ return 16;\n+\n+ case AUDIO_FORMAT_F32:\n+ case AUDIO_FORMAT_S32:\n+ case AUDIO_FORMAT_U32:\n+ return 32;\n+\n+ case AUDIO_FORMAT__MAX:\n+ break;\n+ }\n+\n+ g_assert_not_reached();\n+}\n+\n+static inline bool audio_format_is_float(AudioFormat fmt)\n+{\n+ return fmt == AUDIO_FORMAT_F32;\n+}\n+\n+static inline bool audio_format_is_signed(AudioFormat fmt)\n+{\n+ switch (fmt) {\n+ case AUDIO_FORMAT_S8:\n+ case AUDIO_FORMAT_S16:\n+ case AUDIO_FORMAT_S32:\n+ case AUDIO_FORMAT_F32:\n+ return true;\n+\n+ case AUDIO_FORMAT_U8:\n+ case AUDIO_FORMAT_U16:\n+ case AUDIO_FORMAT_U32:\n+ return false;\n+\n+ case AUDIO_FORMAT__MAX:\n+ break;\n+ }\n+\n+ g_assert_not_reached();\n+}\n+\n #define DEFINE_AUDIO_PROPERTIES(_s, _f) \\\n DEFINE_PROP_AUDIODEV(\"audiodev\", _s, _f)\n \ndiff --git a/audio/audio-mixeng-be.c b/audio/audio-mixeng-be.c\nindex d02cfe3c509..931d5b206f2 100644\n--- a/audio/audio-mixeng-be.c\n+++ b/audio/audio-mixeng-be.c\n@@ -62,23 +62,28 @@ int audio_bug (const char *funcname, int cond)\n return cond;\n }\n \n-static inline int audio_bits_to_index (int bits)\n+/*\n+ * Convert audio format to mixeng_clip index.
