| * ALSA: hda/ca0132: constify parameter table for effectsTakashi Sakamoto2018-05-151-7/+7
| | | | | | | | | | | | | | | | | | | | This module has a table for parameters of each effects. This table is read-only and can have 'const' qualifier. This commit adds this optimization. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds extra functions for shutdown on the Sound Blaster Z and Recon3Di. The Recon3Di only has one specific functions, which sets the GPIO data pins to 0 to prevent a popping noise. The Sound Blaster Z exit sequence was taken from Windows. Without this exit function, the card will not reload properly unless the PC has been shutdown to clear the onboard memory. There are commented out functions currently in the sbz_exit_chip function that are added in a later patch. Also, a reboot notify function has been added, to make sure these functions are ran before a reboot. This helps when using the card through VFIO in a virtual machine, to make sure the card reloads the DSP properly.

| * | | ALSA: emu10k1: Reduce GFP_ATOMIC allocationTakashi Iwai2018-04-162-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The emu10k1 fx8010 code allocates each irq resource dynamically and links to the list at PCM trigger callback. Due to the nature of trigger callback, the allocation is done with GFP_ATOMIC, hence it may fail more often. Moreover, the irq resource isn't big at all, and using the kmalloc for this won't save many bytes, either. This patch removes the dynamic allocation and embeds the irq resource into struct snd_emu10k1_fx8010_pcm.irq field instead of keeping a pointer. As a result, it simplifies the code and removes the unnecessary GFP_ATOMIC usage. Signed-off-by: Takashi Iwai <tiwai@suse.de>

The response value is significant because hda_codec_runtime_suspend() does not clear the codec's bit in the codec_powered bitmask unless the AC_PWRST_CLK_STOP_OK bit (0x200) is set in the response value. That in turn prevents the HDA controller from runtime suspending because azx_runtime_idle() checks that the codec_powered bitmask is zero. Since commit 3b5b899ca67d, hda_set_power_state() only returns 0x0 or 0x1, thereby breaking runtime PM for any HDA controller. That's because an inline function introduced by the commit returns a bool instead of a 32-bit unsigned int. The change was likely erroneous and resulted from copying and pasting snd_hda_check_power_state(), which is immediately preceding the newly introduced inline function. Fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited number of devices available, and HD-audio, especially with HDMI/DP codec, will fail to create more than two devices. The driver warns about the lack of such devices and skips the PCM device creations, but the HDMI driver still tries to create the corresponding JACK, SPDIF and ELD controls even for the non-existing PCM substreams. This results in confusion on user-space, and even may break the operation. Similarly, Intel HDMI/DP codec builds the ELD notification from i915 graphics driver, and this may be broken if a notification is sent for the non-existing PCM stream. This patch adds the check of the existence of the assigned PCM substream in the both scenarios above, and skips the further operation if the PCM substream is not assigned.

This is an additional fix over 92f974df3460 ("ALSA: hda/realtek - New vendor ID for ALC233"). [ More notes: according to Kailang, the chip is 10ec:0235 bonding for ALC233b, which is equivalent with ALC255. It's only used for Lenovo. The chip needs no alc_process_coef_fw() for headset unlike ALC255. ] Signed-off-by: Kailang Yang <kailang@realtek.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | There are two front mics on this machine, if we don't adjust the location for one of them, they will have the same mixer name, pulseaudio can't handle this situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise, the pin will be regarded as microphone, and the jack name is "Mic Phantom", it is always on in the pulseaudio even nothing is plugged into the jack. So the UI is confusing to users since the microphone always shows up in the UI even there is no microphone plugged. After adding this flag, the jack name is "Headset Mic Phantom", then the pulseaudio can handle its detection correctly.

Unfortunately the commit neglected to update the #ifdef surrounding the two functions, so if CONFIG_PM_SLEEP is *not* enabled but all three of CONFIG_PM, CONFIG_VGA_SWITCHEROO and CONFIG_SND_HDA_CODEC_HDMI *are* enabled, the compiler now emits the following warning: sound/pci/hda/hda_intel.c:1024:12: warning: 'azx_resume' defined but not used [-Wunused-function] static int azx_resume(struct device *dev) ^~~~~~~~~~ sound/pci/hda/hda_intel.c:989:12: warning: 'azx_suspend' defined but not used [-Wunused-function] static int azx_suspend(struct device *dev) ^~~~~~~~~~~ Silence by updating the #ifdef. Because the #ifdef block now uses the same condition as the one immediately succeeding it, the two blocks can be collapsed together, shaving off another two lines.
