[PATCH] soundwire: stream: Fix test for DP prepare complete
by Richard Fitzgerald 20 Jun '21

20 Jun '21

In sdw_prep_deprep_slave_ports(), after the wait_for_completion() the DP prepare status register is read. If this indicates that the port is now prepared, the code should continue with the port setup. It is irrelevant whether the wait_for_completion() timed out if the port is now ready. The previous implementation would always fail if the wait_for_completion() timed out, even if the port was reporting successful prepare. This patch also fixes a minor bug where the return from sdw_read() was not checked for error - any error code with LSBits clear could be misinterpreted as a successful port prepare.

[PATCH v2] soundwire: bus: Make sdw_nwrite() data pointer argument const
by Richard Fitzgerald 20 Jun '21

20 Jun '21

Idiomatically, write functions should take const pointers to the data buffer, as they don't change the data. They are also likely to be called from functions that receive a const data pointer. Internally the pointer is passed to function/structs shared with the read functions, requiring a cast, but this is an implementation detail that should be hidden by the public API.

[PATCH] ALSA: hda/realtek: Fix bass speaker DAC mapping for Asus UM431D
by Takashi Iwai 20 Jun '21

20 Jun '21

Asus Zenbook 14 UM431D has two speaker pins and a headphone pin, and the auto-parser ends up assigning the bass to the third DAC 0x06. Although the tone comes out, it's inconvenient because this DAC has no volume control unlike two other DACs. For obtaining the volume control for the bass speaker, this patch enforces the mapping to let both front and bass speaker pins sharing the same DAC. It's not ideal but a little bit of improvement. Since we've already applied the same workaround for another ASUS machine, we just need to hook the chain to the existing quirk.

[PATCH] ALSA: bebob: add support for ToneWeal FW66
by Takashi Sakamoto 20 Jun '21

20 Jun '21

A user of FFADO project reported the issue of ToneWeal FW66. As a result, the device is identified as one of applications of BeBoB solution. I note that in the report the device returns contradictory result in plug discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't perform it thus it's likely to handle the device without issues. I receive no reaction to test request for this patch yet, however it would be worth to add support for it. daniel@gibbonmoon:/sys/bus/firewire/devices/fw1$ grep -r . * Binary file config_rom matches dev:244:1 guid:0x0023270002000000 hardware_version:0x000002 is_local:0 model:0x020002 model_name:FW66 power/runtime_active_time:0 power/runtime_active_kids:0 power/runtime_usage:0 power/runtime_status:unsupported power/async:disabled power/runtime_suspended_time:0 power/runtime_enabled:disabled power/control:auto subsystem/drivers_autoprobe:1 uevent:MAJOR=244 uevent:MINOR=1 uevent:DEVNAME=fw1 units:0x00a02d:0x010001 vendor:0x002327 vendor_name:ToneWeal fw1.0/uevent:MODALIAS=ieee1394:ven00002327mo00020002sp0000A02Dver00010001 fw1.0/power/runtime_active_time:0 fw1.0/power/runtime_active_kids:0 fw1.0/power/runtime_usage:0 fw1.0/power/runtime_status:unsupported fw1.0/power/async:disabled fw1.0/power/runtime_suspended_time:0 fw1.0/power/runtime_enabled:disabled fw1.0/power/control:auto fw1.0/model:0x020002 fw1.0/rom_index:15 fw1.0/specifier_id:0x00a02d fw1.0/model_name:FW66 fw1.0/version:0x010001 fw1.0/modalias:ieee1394:ven00002327mo00020002sp0000A02Dver00010001 Cc: Daniel Jozsef <daniel.jozsef(a)gmail.com> Reference: https://lore.kernel.org/alsa-devel/20200119164335.GA11974@workstation/ Signed-off-by: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> --- sound/firewire/Kconfig | 1 + sound/firewire/bebob/bebob.c | 3 +++ 2 files changed, 4 insertions(+) diff --git a/sound/firewire/Kconfig b/sound/firewire/Kconfig index 62658e2b111a..fd109bea4c53 100644 --- a/sound/firewire/Kconfig +++ b/sound/firewire/Kconfig @@ -127,6 +127,7 @@ config SND_BEBOB * M-Audio Ozonic/NRV10/ProfireLightBridge * M-Audio FireWire 1814/ProjectMix IO * Digidesign Mbox 2 Pro + * ToneWeal FW66 To compile this driver as a module, choose M here: the module will be called snd-bebob. diff --git a/sound/firewire/bebob/bebob.c b/sound/firewire/bebob/bebob.c index 7ca452efb133..42980da45fbf 100644 --- a/sound/firewire/bebob/bebob.c +++ b/sound/firewire/bebob/bebob.c @@ -56,6 +56,7 @@ static DECLARE_BITMAP(devices_used, SNDRV_CARDS); #define VEN_FOCUSRITE 0x0000130e #define VEN_MAUDIO 0x00000d6c #define VEN_DIGIDESIGN 0x00a07e +#define OUI_SHOUYO 0x002327 #define MODEL_FOCUSRITE_SAFFIRE_BOTH 0x00000000 #define MODEL_MAUDIO_AUDIOPHILE_BOTH 0x00010060 @@ -469,6 +470,8 @@ static const struct ieee1394_device_id bebob_id_table[] = { &maudio_special_spec), /* Digidesign Mbox 2 Pro */ SND_BEBOB_DEV_ENTRY(VEN_DIGIDESIGN, 0x0000a9, &spec_normal), + // Toneweal FW66. + SND_BEBOB_DEV_ENTRY(OUI_SHOUYO, 0x020002, &spec_normal), /* IDs are unknown but able to be supported */ /* Apogee, Mini-ME Firewire */ /* Apogee, Mini-DAC Firewire */ -- 2.30.2

[PATCH] soundwire: stream: Use polling for DP Prepare completion
by Richard Fitzgerald 18 Jun '21

18 Jun '21

sdw_prep_deprep_slave_ports() cannot use the port interrupt to signal CP_SM completion because it is called while holding the bus lock, which blocks the alert handler from running. Change to polling the PREPARESTATUS register and remove the infrastructure that was implemented for the previous interrupt waiting. A new configuration field 'ch_prep_poll_us' is added to struct sdw_dpn_prop so that the peripheral driver may select a polling interval. If this is left at zero a default interval of 500 usec is used.

[PATCH] ALSA: firewire-motu: fix rx packet format at higher rate for MOTU 828 mk3 Hybrid
by Takashi Sakamoto 18 Jun '21

18 Jun '21

I assumed that the combination of packet formats for MOTU 828 mk3 Hybrid is the same as MOTU 828 mk3 FireWire. However at higher sampling rate, it is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for rx packet. This commit fixes the issue to which I address at a commit f2ac3b839540 ("ALSA: firewire-motu: sequence replay for source packet header").

Hello Srinivas Kandagatla, The patch d5add08fcbce: "ASoC: codecs: wcd938x: add capture dapm widgets" from Jun 9, 2021, leads to the following static checker warning: sound/soc/codecs/wcd938x.c:2092 wcd938x_tx_swr_ctrl() error: uninitialized symbol 'rate'. sound/soc/codecs/wcd938x.c 2064 switch (event) { 2065 case SND_SOC_DAPM_PRE_PMU: 2066 if (strnstr(w->name, "ADC", sizeof("ADC"))) { Use strncmp() here instead of strnstr(). The sizeof() will include the NUL terminator so it's size 4 and you wanted 3. The off by one means that strnstr() will do two memcmp()s. The equivalent of: if (memcmp(w->name, "ADC", 3) == 0) return w->name; if (memcmp(w->name + 1, "ADC", 3) == 0) return w->name + 1; return NULL; 2067 int i = 0, mode = 0; 2068 2069 if (test_bit(WCD_ADC1, &wcd938x->status_mask)) 2070 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC1]]; 2071 if (test_bit(WCD_ADC2, &wcd938x->status_mask)) 2072 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC2]]; 2073 if (test_bit(WCD_ADC3, &wcd938x->status_mask)) 2074 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC3]]; 2075 if (test_bit(WCD_ADC4, &wcd938x->status_mask)) 2076 mode |= tx_mode_bit[wcd938x->tx_mode[WCD_ADC4]]; 2077 2078 if (mode != 0) { 2079 for (i = 0; i < ADC_MODE_ULP2; i++) { 2080 if (mode & (1 << i)) { 2081 i++; 2082 break; 2083 } 2084 } 2085 } 2086 rate = wcd938x_get_clk_rate(i); 2087 wcd938x_set_swr_clk_rate(component, rate, bank); 2088 } 2089 2090 if (strnstr(w->name, "ADC", sizeof("ADC"))) 2091 /* Copy clk settings to active bank */ 2092 wcd938x_set_swr_clk_rate(component, rate, !bank); This a false positive, but you could silence it by combining it with the previous if block. 2093 break; 2094 case SND_SOC_DAPM_POST_PMD: 2095 if (strnstr(w->name, "ADC", sizeof("ADC"))) { 2096 rate = wcd938x_get_clk_rate(ADC_MODE_INVALID); 2097 wcd938x_set_swr_clk_rate(component, rate, !bank); 2098 wcd938x_set_swr_clk_rate(component, rate, bank); 2099 } 2100 break; 2101 } regards, dan carpenter
