[PATCH 1/3] ASoC: cs35l45: Use modern pm_ops
by Ricardo Rivera-Matos 07 Dec '23

07 Dec '23

Make use of the recently introduced EXPORT_GPL_DEV_PM_OPS() macro, to conditionally export the runtime/system PM functions. Replace the old SET_{RUNTIME,SYSTEM_SLEEP,NOIRQ_SYSTEM_SLEEP}_PM_OPS() helpers with their modern alternatives and get rid of the now unnecessary '__maybe_unused' annotations on all PM functions. Additionally, use the pm_ptr() macro to fix the following errors when building with CONFIG_PM disabled: Signed-off-by: Ricardo Rivera-Matos <rriveram(a)opensource.cirrus.com> Acked-by: Charles Keepax <ckeepax(a)opensource.cirrus.com> --- sound/soc/codecs/cs35l45-i2c.c | 2 +- sound/soc/codecs/cs35l45-spi.c | 2 +- sound/soc/codecs/cs35l45.c | 9 ++++----- 3 files changed, 6 insertions(+), 7 deletions(-) diff --git a/sound/soc/codecs/cs35l45-i2c.c b/sound/soc/codecs/cs35l45-i2c.c index 77e0f8750f37..bc2af1ed0fe9 100644 --- a/sound/soc/codecs/cs35l45-i2c.c +++ b/sound/soc/codecs/cs35l45-i2c.c @@ -62,7 +62,7 @@ static struct i2c_driver cs35l45_i2c_driver = { .driver = { .name = "cs35l45", .of_match_table = cs35l45_of_match, - .pm = &cs35l45_pm_ops, + .pm = pm_ptr(&cs35l45_pm_ops), }, .id_table = cs35l45_id_i2c, .probe = cs35l45_i2c_probe, diff --git a/sound/soc/codecs/cs35l45-spi.c b/sound/soc/codecs/cs35l45-spi.c index 5efb77530cc3..39e203a5f060 100644 --- a/sound/soc/codecs/cs35l45-spi.c +++ b/sound/soc/codecs/cs35l45-spi.c @@ -64,7 +64,7 @@ static struct spi_driver cs35l45_spi_driver = { .driver = { .name = "cs35l45", .of_match_table = cs35l45_of_match, - .pm = &cs35l45_pm_ops, + .pm = pm_ptr(&cs35l45_pm_ops), }, .id_table = cs35l45_id_spi, .probe = cs35l45_spi_probe, diff --git a/sound/soc/codecs/cs35l45.c b/sound/soc/codecs/cs35l45.c index b68853e42fd1..4f4df166f5f0 100644 --- a/sound/soc/codecs/cs35l45.c +++ b/sound/soc/codecs/cs35l45.c @@ -982,7 +982,7 @@ static int cs35l45_exit_hibernate(struct cs35l45_private *cs35l45) return -ETIMEDOUT; } -static int __maybe_unused cs35l45_runtime_suspend(struct device *dev) +static int cs35l45_runtime_suspend(struct device *dev) { struct cs35l45_private *cs35l45 = dev_get_drvdata(dev); @@ -999,7 +999,7 @@ static int __maybe_unused cs35l45_runtime_suspend(struct device *dev) return 0; } -static int __maybe_unused cs35l45_runtime_resume(struct device *dev) +static int cs35l45_runtime_resume(struct device *dev) { struct cs35l45_private *cs35l45 = dev_get_drvdata(dev); int ret; @@ -1466,10 +1466,9 @@ void cs35l45_remove(struct cs35l45_private *cs35l45) } EXPORT_SYMBOL_NS_GPL(cs35l45_remove, SND_SOC_CS35L45); -const struct dev_pm_ops cs35l45_pm_ops = { - SET_RUNTIME_PM_OPS(cs35l45_runtime_suspend, cs35l45_runtime_resume, NULL) +EXPORT_GPL_DEV_PM_OPS(cs35l45_pm_ops) = { + RUNTIME_PM_OPS(cs35l45_runtime_suspend, cs35l45_runtime_resume, NULL) }; -EXPORT_SYMBOL_NS_GPL(cs35l45_pm_ops, SND_SOC_CS35L45); MODULE_DESCRIPTION("ASoC CS35L45 driver"); MODULE_AUTHOR("James Schulman, Cirrus Logic Inc, <james.schulman(a)cirrus.com>"); -- 2.34.1

alsa-project/alsa-ucm-conf issue #371 was edited from ricciolino: I posted [this](https://ubuntuforums.org/showthread.php?t=2486774) some weeks ago and I thought I had been able to solve the issue. Unfortunately, it does not seem like so. **Summary of the issue**: attaching my headphone to the rear jack, sound is emitted correctly, whilst frontal AUX jack it just looks dead (headphone device is correctly recognized in sound system settings but no sound is emitted). Summary of steps that brought me to the initial solution.

[PATCH v2 00/35] bitops: add atomic find_bit() operations
by Yury Norov 07 Dec '23

07 Dec '23

Add helpers around test_and_{set,clear}_bit() that allow to search for clear or set bits and flip them atomically. The target patterns may look like this: for (idx = 0; idx < nbits; idx++) if (test_and_clear_bit(idx, bitmap)) do_something(idx); Or like this: do { bit = find_first_bit(bitmap, nbits); if (bit >= nbits) return nbits; } while (!test_and_clear_bit(bit, bitmap)); return bit; In both cases, the opencoded loop may be converted to a single function or iterator call. Correspondingly: for_each_test_and_clear_bit(idx, bitmap, nbits) do_something(idx); Or: return find_and_clear_bit(bitmap, nbits); Obviously, the less routine code people have to write themself, the less probability to make a mistake. Those are not only handy helpers but also resolve a non-trivial issue of using non-atomic find_bit() together with atomic test_and_{set,clear)_bit(). The trick is that find_bit() implies that the bitmap is a regular non-volatile piece of memory, and compiler is allowed to use such optimization techniques like re-fetching memory instead of caching it. For example, find_first_bit() is implemented like this: for (idx = 0; idx * BITS_PER_LONG < sz; idx++) { val = addr[idx]; if (val) { sz = min(idx * BITS_PER_LONG + __ffs(val), sz); break; } } On register-memory architectures, like x86, compiler may decide to access memory twice - first time to compare against 0, and second time to fetch its value to pass it to __ffs(). When running find_first_bit() on volatile memory, the memory may get changed in-between, and for instance, it may lead to passing 0 to __ffs(), which is undefined. This is a potentially dangerous call. find_and_clear_bit() as a wrapper around test_and_clear_bit() naturally treats underlying bitmap as a volatile memory and prevents compiler from such optimizations. Now that KCSAN is catching exactly this type of situations and warns on undercover memory modifications. We can use it to reveal improper usage of find_bit(), and convert it to atomic find_and_*_bit() as appropriate. The 1st patch of the series adds the following atomic primitives: find_and_set_bit(addr, nbits); find_and_set_next_bit(addr, nbits, start); ... Here find_and_{set,clear} part refers to the corresponding test_and_{set,clear}_bit function. Suffixes like _wrap or _lock derive their semantics from corresponding find() or test() functions. For brevity, the naming omits the fact that we search for zero bit in find_and_set, and correspondingly search for set bit in find_and_clear functions. The patch also adds iterators with atomic semantics, like for_each_test_and_set_bit(). Here, the naming rule is to simply prefix corresponding atomic operation with 'for_each'. This series is a result of discussion [1]. All find_bit() functions imply exclusive access to the bitmaps. However, KCSAN reports quite a number of warnings related to find_bit() API. Some of them are not pointing to real bugs because in many situations people intentionally allow concurrent bitmap operations. If so, find_bit() can be annotated such that KCSAN will ignore it: bit = data_race(find_first_bit(bitmap, nbits)); This series addresses the other important case where people really need atomic find ops. As the following patches show, the resulting code looks safer and more verbose comparing to opencoded loops followed by atomic bit flips. In [1] Mirsad reported 2% slowdown in a single-thread search test when switching find_bit() function to treat bitmaps as volatile arrays. On the other hand, kernel robot in the same thread reported +3.7% to the performance of will-it-scale.per_thread_ops test. Assuming that our compilers are sane and generate better code against properly annotated data, the above discrepancy doesn't look weird. When running on non-volatile bitmaps, plain find_bit() outperforms atomic find_and_bit(), and vice-versa. So, all users of find_bit() API, where heavy concurrency is expected, are encouraged to switch to atomic find_and_bit() as appropriate. The 1st patch of this series adds atomic find_and_bit() API, 2nd adds a basic test for new API, and all the following patches spread it over the kernel. They can be applied separately from each other on per-subsystems basis, or I can pull them in bitmap tree, as appropriate.

[PATCH 00/16] ALSA: hda/tas2781: Add tas2563 support
by Gergo Koteles 07 Dec '23

07 Dec '23

The tas2781-hda driver can be modified to support tas2563 as well. Before knowing this information, I created another series for a new driver. https://lore.kernel.org/lkml/cover.1701733441.git.soyer@irl.hu/ This series now extends tas2781-hda, addresses differences and fixes various bugs. The tas2563 is a smart amplifier. Similar to tas2562 but with DSP. Some Lenovo laptops have it to drive the bass speakers. By default, it is in software shutdown state. To make the DSP work it needs a firmware and some calibration data. The latter can be read from the EFI in Lenovo laptops. For the correct configuration it needs additional register data. It captured after running the Windows driver. The firmware can be extracted as TAS2563Firmware.bin from the Windows driver with innoextract. https://download.lenovo.com/consumer/mobiles/h5yd037fbfyy7kd0.exe The driver will search for it as TAS2XXX3870.bin with the 14ARB7.

aplay: fix buffer overflow and tainted format string

alsa-project/alsa-utils pull request #246 was opened from szsam: Prior this commit, memcpy from names[0] to format[] will overwrite if strlen(names[0]) is greater than 1024. Also, the length of malloc()ed names[channel] is insufficient, leading to another buffer overwriting when calling sprintf(). Moreover, the format string of sprintf() can be controlled by user input. An attacker can exploit this weakness to crash the program, disclose information or even execute arbitrary code. Fix by allocating enough space for arrays and using constant expressions as the format strings.
