[alsa-devel] [PATCH] ALSA: emu10k1: Fix forgotten user-copy conversion in init code
by Takashi Iwai 18 Aug '17

18 Aug '17

The commit d42fe63d5839 ("ALSA: emu10k1: Get rid of set_fs() usage") converted the user-space copy hack with set_fs() to the direct memcpy(), but one place was forgotten. This resulted in the error from snd_emu10k1_init_efx(), eventually failed to load the driver. Fix the missing piece.

[alsa-devel] [PATCH] ALSA: usb-audio: don't retry snd_usb_ctl_msg after timeout
by Stephen Barber 18 Aug '17

18 Aug '17

A few calls to snd_usb_ctl_msg wrap the function in a retry loop. In the worst case, the timeout for snd_usb_ctl_msg is 5 seconds, which when retried 10 times (for example, if a device is removed) could cause a probe to hang for ~50 seconds. Example stack trace from 3.14 which triggered a hung task timeout: Call Trace: [<ffffffffa2c1f720>] ? inet6_set_link_af.part.35+0x12/0x12 [<ffffffffa2c20309>] schedule+0x6e/0x70 [<ffffffffa2c1f81c>] schedule_timeout+0xfc/0x13c [<ffffffffa2667bbc>] ? rcu_read_unlock_sched_notrace+0x17/0x17 [<ffffffffa2c20d68>] __wait_for_common+0x153/0x190 [<ffffffffa2c20d68>] ? __wait_for_common+0x153/0x190 [<ffffffffa26890e5>] ? wake_up_state+0x12/0x12 [<ffffffffa2c20e0e>] wait_for_completion_timeout+0x1d/0x1f [<ffffffffa2a07c70>] usb_start_wait_urb+0x93/0xf1 [<ffffffffa2a07daf>] usb_control_msg+0xe1/0x11d [<ffffffffc02cd254>] snd_usb_ctl_msg+0x9c/0xf1 [snd_usb_audio] [<ffffffffc02ce191>] snd_usb_mixer_set_ctl_value+0x124/0xab1 [snd_usb_audio] [<ffffffffc02ce230>] snd_usb_mixer_set_ctl_value+0x1c3/0xab1 [snd_usb_audio] [<ffffffffc02ce58e>] snd_usb_mixer_set_ctl_value+0x521/0xab1 [snd_usb_audio] [<ffffffffc02cee88>] snd_usb_mixer_add_control+0x36a/0x1264 [snd_usb_audio] [<ffffffffc02cf323>] snd_usb_mixer_add_control+0x805/0x1264 [snd_usb_audio] [<ffffffffa2a06e11>] ? usb_free_urb+0x1a/0x1c [<ffffffffc02cfcf7>] snd_usb_mixer_add_control+0x11d9/0x1264 [snd_usb_audio] [<ffffffffc02d000f>] snd_usb_create_mixer+0xbc/0x286 [snd_usb_audio] [<ffffffffc02cac18>] 0xffffffffc02cac17 [<ffffffffa2a0aaf1>] usb_probe_interface+0x17c/0x21c [<ffffffffa29a65bc>] driver_probe_device+0xae/0x1fa [<ffffffffa29a6767>] __device_attach_driver+0x5f/0x66 [<ffffffffa29a6708>] ? driver_probe_device+0x1fa/0x1fa [<ffffffffa29a4a60>] bus_for_each_drv+0x87/0xaa [<ffffffffa29a688a>] __device_attach+0x9d/0x101 [<ffffffffa29a6913>] device_initial_probe+0x13/0x15 [<ffffffffa29a5ae6>] bus_probe_device+0x33/0x96 [<ffffffffa29a3d19>] device_add+0x328/0x547 [<ffffffffa2a09355>] usb_set_configuration+0x624/0x674 [<ffffffffa2a11949>] generic_probe+0x45/0x77 [<ffffffffa2a0a962>] usb_probe_device+0x2d/0x40 [<ffffffffa29a65bc>] driver_probe_device+0xae/0x1fa [<ffffffffa29a6767>] __device_attach_driver+0x5f/0x66 [<ffffffffa29a6708>] ? driver_probe_device+0x1fa/0x1fa [<ffffffffa29a4a60>] bus_for_each_drv+0x87/0xaa [<ffffffffa29a688a>] __device_attach+0x9d/0x101 [<ffffffffa29a6913>] device_initial_probe+0x13/0x15 [<ffffffffa29a5ae6>] bus_probe_device+0x33/0x96 [<ffffffffa29a3d19>] device_add+0x328/0x547 [<ffffffffa29030bc>] ? add_device_randomness+0x111/0x130 [<ffffffffa2a00967>] usb_new_device+0x2a2/0x3c0 [<ffffffffa2a02ddc>] hub_thread+0xa3d/0xeed [<ffffffffa2c2010d>] ? __schedule+0x41e/0x5ac [<ffffffffa26957ce>] ? finish_wait+0x62/0x62 [<ffffffffa2a0239f>] ? usb_reset_device+0x16a/0x16a [<ffffffffa267b255>] kthread+0x108/0x110 [<ffffffffa267b14d>] ? __kthread_parkme+0x67/0x67 [<ffffffffa2c23b2c>] ret_from_fork+0x7c/0xb0 [<ffffffffa267b14d>] ? __kthread_parkme+0x67/0x67 Signed-off-by: Stephen Barber <smbarber(a)chromium.org> --- sound/usb/mixer.c | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-) diff --git a/sound/usb/mixer.c b/sound/usb/mixer.c index 082736c539bc..253fc946db29 100644 --- a/sound/usb/mixer.c +++ b/sound/usb/mixer.c @@ -318,12 +318,15 @@ static int get_ctl_value_v1(struct usb_mixer_elem_info *cval, int request, while (timeout-- > 0) { idx = snd_usb_ctrl_intf(chip) | (cval->head.id << 8); - if (snd_usb_ctl_msg(chip->dev, usb_rcvctrlpipe(chip->dev, 0), request, - USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_IN, - validx, idx, buf, val_len) >= val_len) { + err = snd_usb_ctl_msg(chip->dev, usb_rcvctrlpipe(chip->dev, 0), request, + USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_IN, + validx, idx, buf, val_len); + if (err >= val_len) { *value_ret = convert_signed_value(cval, snd_usb_combine_bytes(buf, val_len)); err = 0; goto out; + } else if (err == -ETIMEDOUT) { + goto out; } } usb_audio_dbg(chip, @@ -483,12 +486,15 @@ int snd_usb_mixer_set_ctl_value(struct usb_mixer_elem_info *cval, while (timeout-- > 0) { idx = snd_usb_ctrl_intf(chip) | (cval->head.id << 8); - if (snd_usb_ctl_msg(chip->dev, - usb_sndctrlpipe(chip->dev, 0), request, - USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_OUT, - validx, idx, buf, val_len) >= 0) { + err = snd_usb_ctl_msg(chip->dev, + usb_sndctrlpipe(chip->dev, 0), request, + USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_OUT, + validx, idx, buf, val_len); + if (err >= 0) { err = 0; goto out; + } else if (err == -ETIMEDOUT) { + goto out; } } usb_audio_dbg(chip, "cannot set ctl value: req = %#x, wValue = %#x, wIndex = %#x, type = %d, data = %#x/%#x\n", -- 2.14.1.480.gb18f417b89-goog

[alsa-devel] Digigram VX222e not seen as card
by Sam Mulvey 18 Aug '17

18 Aug '17

A radio station I'm working on has a machine with a Digigram VX222e connected to it. According to the Digigram site and the ALSA website, the sound card is supported by ALSA. Unfortunately, it doesn't appear to be detected as a sound card. Reading online, it requires some firmware, but it appears that my system has the proper firmware installed. The VX222e is a PCIe card, but it appears to be PCI on the card with a PCIe to PCI bridge. According to Digigram's support site, they made a hardware change in March of 2017, and I suspect that this might be the problem. I'm guessing it might be as simple enough as an ID match that I need to add to a module, but I've never worked with the card before, and I'm a little stuck. There's nothing regarding the card in dmesg, but it is visible in lspci: 03:00.0 PCI bridge: PLX Technology, Inc.

[alsa-devel] [PATCH] ASoC: tegra: Remove SoC-specific Kconfig depends and selects
by Paul Kocialkowski 17 Aug '17

17 Aug '17

This removes the SoC-specific dependencies on the platform drivers, as well as SoC-specific selections of platform drivers for the machine drivers. The rationale behind this change is that the dependencies are not actual build dependencies but run-time ones. The previously listed SoCs were also incomplete: for instance, tegra124 uses the tegra30 platform drivers, which could not be built without ARCH_TEGRA_3x_SOC set. Descriptions of the tristates are also added to allow these options to be set via defconfig/menuconfig.

[alsa-devel] Applied "ASoC: codec: use enable pin to control dmic start and stop" to the asoc tree
by Mark Brown 17 Aug '17

17 Aug '17

The patch ASoC: codec: use enable pin to control dmic start and stop has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.
