Clang warns: sound/ppc/beep.c:103:2: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough] case SND_TONE: break; ^ sound/ppc/beep.c:103:2: note: insert 'break;' to avoid fall-through case SND_TONE: break; ^ break; 1 warning generated. Clang is more pedantic than GCC, which does not warn when failing through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst. Add athe missing break to silence the warning.

2021-11-29ALSA: hda: Make proper use of timecounterThomas Gleixner
HDA uses a timecounter to read a hardware clock running at 24 MHz. The conversion factor is set with a mult value of 125 and a shift value of 0, which is not converting the hardware clock to nanoseconds, it is converting to 1/3 nanoseconds because the conversion factor from 24Mhz to nanoseconds is 125/3. The usage sites divide the "nanoseconds" value returned by timecounter_read() by 3 to get a real nanoseconds value. There is a lengthy comment in azx_timecounter_init() explaining this choice. That comment makes blatantly wrong assumptions about how timecounters work and what can overflow. The comment says: * Applying the 1/3 factor as part of the multiplication * requires at least 20 bits for a decent precision, however * overflows occur after about 4 hours or less, not a option. timecounters operate on time deltas between two readouts of a clock and use the mult/shift pair to calculate a precise nanoseconds value: delta_nsec = (delta_clock * mult) >> shift; The fractional part is also taken into account and preserved to prevent accumulated rounding errors. For details see cyclecounter_cyc2ns(). The mult/shift pair has to be chosen so that the multiplication of the maximum expected delta value does not result in a 64bit overflow. As the counter wraps around on 32bit, the maximum observable delta between two reads is (1 << 32) - 1 which is about 178.9 seconds. That in turn means the maximum multiplication factor which fits into an u32 will not cause a 64bit overflow ever because it's guaranteed that: ((1 << 32) - 1) ^ 2 < (1 << 64) The resulting correct multiplication factor is 2796202667 and the shift value is 26, i.e. 26 bit precision. The overflow of the multiplication would happen exactly at a clock readout delta of 6597069765 which is way after the wrap around of the hardware clock at around 274.8 seconds which is off from the claimed 4 hours by more than an order of magnitude. If the counter ever wraps around the last read value then the calculation is off by the number of wrap arounds times 178.9 seconds because the overflow cannot be observed. Use clocks_calc_mult_shift(), which calculates the most accurate mult/shift pair based on the given clock frequency, and remove the bogus comment along with the divisions at the readout sites.

2021-11-20ALSA: hda: Remove redundant runtime PM callsTakashi Iwai
The previous fix for more comprehensive runtime PM calls turned out to be not good as hoped; a few calls including pm_runtime_enable() and pm_runtime_disable() are rather utterly superfluous for PCI devices, even triggering a kernel error message. Better to drop those calls. Note that the problem we wanted to solve with that commit seems irrelevant with the fix itself; the original bug (a GPF at azx_remove()) was likely a regression by the recent PCI core cleanup, and the buggy PCI change has been already reverted. So basically we were scratching a wrong surface. OTOH, making the runtime PM calls symmetric for both probe and remove is more consistent, and maybe that's a sensible outcome.

The HD-audio codec driver remove may happen also at dynamically unbinding during operation, hence it needs manual triggers of snd_device_disconnect() calls, while it's missing for the jack objects that are associated with the codec. This patch adds the manual disconnection call for jacks when the remove happens without card->shutdown (i.e. not under the full removal).

2021-11-16ALSA: memalloc: Unify x86 SG-buffer handling (take#3)Takashi Iwai
This is a second attempt to unify the x86-specific SG-buffer handling code with the new standard non-contiguous page handler. The first try (in commit 2d9ea39917a4) failed due to the wrong page and address calculations, hence reverted. (And the second try failed due to a copy&paste error.) Now it's corrected with the previous fix for noncontig pages, and the proper sg page iteration by this patch. After the migration, SNDRV_DMA_TYPE_DMA_SG becomes identical with SNDRV_DMA_TYPE_NONCONTIG on x86, while others still fall back to SNDRV_DMA_TYPE_DEV.

2021-11-16ALSA: hda: Fix potential deadlock at codec unbindingTakashi Iwai
When a codec is unbound dynamically via sysfs while its stream is in use, we may face a potential deadlock at the proc remove or a UAF. This happens since the hda_pcm is managed by a linked list, as it handles the hda_pcm object release via kref. When a PCM is opened at the unbinding time, the release of hda_pcm gets delayed and it ends up with the close of the PCM stream releasing the associated hda_pcm object of its own. The hda_pcm destructor contains the PCM device release that includes the removal of procfs entries. And, this removal has the sync of the close of all in-use files -- which would never finish because it's called from the PCM file descriptor itself, i.e. it's trying to shoot its foot. For addressing the deadlock above, this patch changes the way to manage and release the hda_pcm object. The kref of hda_pcm is dropped, and instead a simple refcount is introduced in hda_codec for keeping the track of the active PCM streams, and at each PCM open and close, this refcount is adjusted accordingly. At unbinding, the driver calls snd_device_disconnect() for each PCM stream, then synchronizes with the refcount finish, and finally releases the object resources.

2021-11-15ALSA: hda: intel: More comprehensive PM runtime setup for controller driverTakashi Iwai
Currently we haven't explicitly enable and allow/forbid the runtime PM at the probe and the remove phases of HD-audio controller driver, and this was the reason of a GPF mentioned in the commit e81478bbe7a1 ("ALSA: hda: fix general protection fault in azx_runtime_idle"); namely, even after the resources are released, the runtime PM might be still invoked by the bound graphics driver during the remove of the controller driver. Although we've fixed it by clearing the drvdata reference, it'd be also better to cover the runtime PM issue more properly. This patch adds a few more pm_runtime_*() calls at the probe and the remove time for setting and cleaning up the runtime PM. Particularly, now more explicitly pm_runtime_enable() and _disable() get called as well as pm_runtime_forbid() call at the remove callback, so that a use-after-free should be avoided.

2021-11-10ALSA: hda: Free card instance properly at probe errorsTakashi Iwai
The recent change in hda-intel driver to allow repeated probes surfaced a problem that has been hidden until; the probe process in the work calls azx_free() at the error path, and this skips the card free process that eventually releases codec instances. As a result, we get a kernel WARNING like: snd_hda_intel 0000:00:1f.3: Cannot probe codecs, giving up ------------[ cut here ]------------ WARNING: CPU: 14 PID: 186 at sound/hda/hdac_bus.c:73 .... For fixing this, we need to call snd_card_free() instead of azx_free(). Additionally, the device drvdata has to be cleared, as the driver binding itself is still active. Then the PM and other driver callbacks will ignore the procedure.

The recently introduced non-contiguous page allocation support helpers are using the simplified code to calculate the page and DMA address based on the vmalloc helpers, but this isn't quite right as the vmap is valid only for the direct DMA.

2021-11-08ALSA: pci: rme: Fix unaligned buffer addressesTakashi Iwai
The recent fix for setting up the DMA buffer type on RME drivers tried to address the non-standard memory managements and changed the DMA buffer information to the standard snd_dma_buffer object that is allocated at the probe time. However, I overlooked that the RME drivers handle the buffer addresses based on 64k alignment, and the previous conversion broke that silently. This patch is an attempt to fix the regression. The snd_dma_buffer objects are copied to the original data with the correction to the aligned accesses, and those are passed to snd_pcm_set_runtime_buffer() helpers instead. The original snd_dma_buffer objects are managed by devres, hence they'll be released automagically.

It consists of below ICs: * Texas Instruments TSB41AB1 * Microchip (SMSC) USB3300 * Xilinx Spartan-3A FPGA, XC3S700A * Texas Instruments TMS320C6722 * Microchip (Atmel) AT91SAM SAM7S512 It supports sampling transfer frequency up to 192.0 kHz. The packet format differs depending on both of current sampling transfer frequency and the type of signal in optical interfaces. The model supports transmission of PCM frames as well as MIDI messages. The model supports command mechanism to configure internal DSP. Hardware meter information is available in the first 2 chunks of each data block of tx packet.

When the timer instance was add into ack_list but was not currently in process, the user could stop it via snd_timer_stop1() without delete it from the ack_list. Then the user could free the timer instance and when it was actually processed UAF occurred. This issue could be reproduced via testcase snd_timer01 in ltp - running several instances of that testcase at the same time. What I actually met was that the ack_list of the timer broken and the kernel went into deadloop with irqoff. That could be detected by hardlockup detector on board or when we run it on qemu, we could use gdb to dump the ack_list when the console has no response. To fix this issue, we delete the timer instance from ack_list and active_list unconditionally in snd_timer_stop1().

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.16 This is an unusually large set of updates, mostly a large crop of unusually big drivers coupled with extensive overhauls of existing code. There's a SH change here for the DAI format terminology, the change is straightforward and the SH maintainers don't seem very active. - A new version of the audio graph card which supports a wider range of systems. - Move of the Cirrus DSP framework into drivers/firmware to allow for future use by non-audio DSPs. - Several conversions to YAML DT bindings. - Continuing cleanups to the SOF and Intel code. - A very big overhaul of the cs42l42 driver, correcting many problems. - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS, RT5682S, and RT9120 and Rockchip RV1126 and RK3568
