| 9c6493d | Matthias Reichl | 08 June 2016, 11:09:56 UTC | dmaengine: bcm2835: Avoid splitting periods into very small chunks The current cyclic DMA period splitting implementation can generate very small chunks at the end of each period. For example a 65536 byte period will be split into a 65532 byte chunk and a 4 byte chunk on the "lite" DMA channels. This increases pressure on the RAM controller as the DMA controller needs to fetch two control blocks from RAM in quick succession and could potentially cause latency issues if the RAM is tied up by other devices. We can easily avoid these situations by distributing the remaining length evenly between the last-but-one and the last chunk, making sure that split chunks will be at least half the maximum length the DMA controller can handle. This patch checks if the last chunk would be less than half of the maximum DMA length and if yes distributes the max len+4...max_len*1.5 bytes evenly between the last 2 chunks. This results in chunk sizes between max_len/2 and max_len*0.75 bytes.

Therefore total_len was stuck at 0 and the code didn't work at all. This resulted in a wrong control block layout and audio issues because the cyclic DMA callback wasn't executing on period boundaries. Fix this by adding the missing total_len update.

This allows automatic detection. Based on this the maximum block size is set to (64K - 4) or to 1G and this limit is honored during generation of control block chains. The effect is that when a LITE channel is used more control blocks are used to do the same transfer (compared to a normal channel). As there are several sources/target DREQS that are 32 bit wide we need to have the transfer to be a multiple of 4 as this would break the transfer otherwise. This is why the limit of (64K - 4) was chosen over the alternative of (64K - 4K).

As a result, when the overlays were modified for dynamic loading and it was discovered that the hifiberry-dac overlay didn't work any more, the the rpi-dac overlay was also broken. The failure was caused by the fact that outside a bus, device names are constructed from the concatenation of the path elements leading to it, so moving the codec instantiation inside /soc caused the device name to get a "soc" added, breaking ALSA's naming.

To do this it installs a pm_power_off handler, causing the gpio-poweroff module to abort the probe function. This patch introduces a "force" DT property that overrides that behaviour, and also adds a DT overlay to enable and control it. Note that running in an active-low configuration (DT parameter "active_low") requires a custom dt-blob.bin and probably won't allow a reboot without switching off, so an external inversion of the trigger signal may be preferable. | 19 August 2016, 14:39:09 UTC |
