* | | | ASoC: intel: atom: Revert PCM buffer address setup workaround againTakashi Iwai2021-08-231-1/+1
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We worked around the breakage of PCM buffer setup by the commit 65ca89c2b12c ("ASoC: intel: atom: Fix breakage for PCM buffer address setup"), but this isn't necessary since the CONTINUOUS buffer type also sets runtime->dma_addr since commit f84ba106a018 ("ALSA: memalloc: Store snd_dma_buffer.addr for continuous pages, too"). Let's revert the change again. Link: https://lore.kernel.org/r/20210822072127.9786-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 2e6b836312a4 ("ASoC: intel: atom: Fix reference to PCM buffer address") changed the reference of PCM buffer address to substream->runtime->dma_addr as the buffer address may change dynamically. However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.

* | ASoC: intel: atom: Fix reference to PCM buffer addressTakashi Iwai2021-07-301-2/+1
|/ | | | | | | | | | | | | | | | | | PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The address should be retrieved from runtime->dma_addr, instead of substream->dma_buffer (and shouldn't use virt_to_phys). Also, remove the line overriding runtime->dma_area superfluously, which was already set up at the PCM buffer allocation.

* | ASoC: intel: atom: Stop advertising non working S24LE supportHans de Goede2021-03-241-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | The SST firmware's media and deep-buffer inputs are hardcoded to S16LE, the corresponding DAIs don't have a hw_params callback and their prepare callback also does not take the format into account. So far the advertising of non working S24LE support has not caused issues because pulseaudio defaults to S16LE, but changing pulse-audio's config to use S24LE will result in broken sound. Pipewire is replacing pulse now and pipewire prefers S24LE over S16LE when available, causing the problem of the broken S24LE support to come to the surface now.

SND_SST_IPC is the core component, required for PCI and ACPI based atom platforms both. _PCI and _ACPI target Merrifield/Edison and Baytrial/Cherrytrail platforms respectively. On top of that, there is an equivalent set of configs targeting the same solution: - SND_SST_ATOM_HIFI2_PLATFORM (core) - SND_SST_ATOM_HIFI2_PLATFORM_PCI - SND_SST_ATOM_HIFI2_PLATFORM_ACPI As both sets do the same job - allow for granular platform selection - remove the duplicate set and rely on SND_SST_ATOM_HIFI2_PLATOFRM_XXX configs alone.

The only effect of avoiding the loop is not initializing the index variable. Drop list_empty tests in cases where these variables are not used. Note that list_for_each_entry_safe is defined in terms of list_first_entry, which indicates that it should not be used on an empty list. But in list_for_each_entry_safe, the element obtained by list_first_entry is not really accessed, only the address of its list_head field is compared to the address of the list head, so the list_first_entry is safe.

* ASoC: Intel: Skylake: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.
