ALSA PCM core has an optimized way to communicate with user-space for its control and status data via mmap on the supported architectures like x86. Depending on the situation, however, we'd rather want to enforce user-space notifying the applptr or hwptr change explicitly via ioctl. For example, the upcoming non-contig and non-coherent buffer handling would need an explicit sync, and this needs to catch the applptr and hwptr changes. Also, ASoC SOF driver will have the SPIB support that has the similar requirement for the explicit control of the applptr and hwptr. This patch adds the new PCM hardware info flag, SNDRV_PCM_INFO_EXPLICIT_SYNC. When this flag is set, PCM core disables both the control and the status mmap, which enforces user-space to update via SYNC_PTR ioctl. In that way, drivers can catch the applptr and hwptr update and apply the sync operation if needed.

This adds a second mixer control to Digidesign Mbox to select between Analog/SPDIF capture. Users will note that selecting the SPDIF input source automatically switches the clock mode to sync to SPDIF, which is a feature of the hardware. (You can change the clock source back to internal if you want to capture from spdif but not sync to its clock although this mode is probably not recommended). Unfortunately, starting the stream resets both modes to Internally clocked and Analog input mode. Signed-off-by:

This is an enhancement for the SG-style page handling in vmalloc buffer handler to calculate the continuous pages. When snd_sgbuf_get_chunk_size() is called for a vmalloc buffer, currently we return only the size that fits into a single page. However, this API call is rather supposed for obtaining the continuous pages and most of vmalloc or noncontig buffers do have lots of continuous pages indeed. So, in this patch, the callback now calculates the possibly continuous pages up to the given size limit. Note that the end address in the function is calculated from the last byte, hence it's one byte shorter. This is because ofs + size can be above the actual buffer size boundary. Until now, this feature isn't really used, but it'll become useful in a later patch that adds the non-contiguous buffer type that shares the same callback function as vmalloc.

Only disable I2C clock 25 ms after not being used. The current implementation enables and disables the I2C clock for each I2C transaction. Each enable/disable call requires two verb transactions. This means each I2C transaction requires a total of four verb transactions to enable and disable the clock. However, if there are multiple consecutive I2C transactions, it is not necessary to enable and disable the clock each time, instead it is more efficient to enable the clock for the first transaction, and disable it after the final transaction, which would improve performance. This is achieved by using a timeout which disables the clock if no request to enable the clock has occurred for 25 ms. Signed-off-by:

The old ISA MSND driver basically maps the iomem as the DMA buffer. For this type of buffer, we have already the standard mmap helper, snd_pcm_lib_mmap_iomem(). Correct the PCM info, set the DMA address and use the standard helper for handling the mmap on all architectures properly.

CS46xx driver switches the buffer depending on the number of periods, and in some cases it switches to the own buffer without updating the buffer type properly. This may cause a problem with the mmap on exotic architectures that require the own mmap call for the coherent DMA buffer. This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too.

Although the regression of the mmap was fixed in the recent commit dc0dc8a7 ("ALSA: pcm: Fix mmap breakage without explicit buffer setup"), RME9652 and HDSP drivers have still potential issues with their mmap handling. Namely, they use the default mmap handler without the standard buffer preallocation, and PCM core wouldn't use the coherent DMA mapping. It's practically OK on x86, but on some exotic architectures, it wouldn't work. This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too. Link: https://lore.kernel.org/r/20210809071829.22238-3-tiwai@suse.deSigned-off-by:

Currently we check only the substream->dma_buffer as the preset of the buffer configuration for verifying the availability of mmap. But a few drivers rather set up the buffer in the own way without the standard buffer preallocation using substream->dma_buffer, and they miss the proper checks. (Now it's working more or less fine as most of them are running only on x86). Actually, they may set up the runtime dma_buffer (referred via snd_pcm_get_dma_buf()) at the open callback, though. That is, this could have been used as the primary source. This patch changes the hw_support_mmap() function to check the runtime dma buffer at first. It's usually NULL with the standard buffer preallocation, and in that case, we continue checking substream->dma_buffer as fallback.

Harmony driver never uses CONTINUOUS buffer type any longer, hence the code setting the address is superfluous. Moreover, the recent change in the ALSA core already covered the missing address field; it's already set up. So let's drop the superfluous line, which includes the full hw_params callback.

The recent fix c4824ae7 ("ALSA: pcm: Fix mmap capability check") restricts the mmap capability only to the drivers that properly set up the buffers, but it caused a regression for a few drivers that manage the buffer on its own way. For those with UNKNOWN buffer type (i.e. the uninitialized / unused substream->dma_buffer), just assume that the driver handles the mmap properly and blindly trust the hardware info bit.
