2019-01-07dmaengine: qcom: bam_dma: use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-01-07dmaengine: dw: Don't pollute CTL_LO on iDMA 32-bitAndy Shevchenko
Intel iDMA 32-bit doesn't have a concept of bus masters and thus there is no need to setup any kind of masters in the CTL_LO register. Moreover, the burst size for memory-to-memory transfer is not what is says, we need to have a corrected list of possible sizes. Note, that the size of 8 items, each of that up to 4 bytes, is chosen because of maximum of 1/2 FIFO, which is 64 bytes on Intel Merrifield.

2019-01-07dmaengine: dw: Remove unused internal propertyAndy Shevchenko
All known devices, which use DT for configuration, support memory-to-memory transfers. So enable it by default. The rest two cases, i.e. Intel Quark and PPC460ex, instantiate DMA driver and use its channels exclusively for hardware, which means there is no available channel for any other purposes anyway.

2019-01-07dmaengine: dw: Remove misleading is_private propertyAndy Shevchenko
The commit a9ddb575d6d6 ("dmaengine: dw_dmac: Enhance device tree support") introduces is_private property in uncertain understanding what does it mean. First of all, documentation defines DMA_PRIVATE capability as Documentation/crypto/async-tx-api.txt: The DMA_PRIVATE capability flag is used to tag dma devices that should not be used by the general-purpose allocator. It can be set at initialization time if it is known that a channel will always be private. Alternatively, it is set when dma_request_channel() finds an unused "public" channel. A couple caveats to note when implementing a driver and consumer: 1/ Once a channel has been privately allocated it will no longer be considered by the general-purpose allocator even after a call to dma_release_channel(). 2/ Since capabilities are specified at the device level a dma_device with multiple channels will either have all channels public, or all channels private. Documentation/driver-api/dmaengine/provider.rst: - DMA_PRIVATE The devices only supports slave transfers, and as such isn't available for async transfers. The capability had been introduced by the commit 59b5ec21446b ("dmaengine: introduce dma_request_channel and private channels") and some code didn't changed from that times ever. Taking into consideration above and the fact that on all known platforms Synopsys DesignWare DMA engine is attached to serve slave transfers, the DMA_PRIVATE capability must be enabled for this device unconditionally. Otherwise, as rightfully noticed in drivers/dma/at_xdmac.c: /* * Without DMA_PRIVATE the driver is not able to allocate more than * one channel, second allocation fails in private_candidate. */ because of of a caveats mentioned in above documentation excerpts. So, remove conditional around DMA_PRIVATE followed by removal leftovers. If someone wonders, DMA_PRIVATE can be not used if and only if the all channels of the DMA controller are supposed to serve memory-to-memory like operations. For example, EP93xx has two controllers, one of which can only perform memory-to-memory transfers Note, this change doesn't affect dmatest to be able to test such controllers.

2019-01-07dmaengine: xilinx_dma: in axidma slave_sg and dma_cyclic mode align split ↵Andrea Merello
descriptors Whenever a single or cyclic transaction is prepared, the driver could eventually split it over several SG descriptors in order to deal with the HW maximum transfer length. This could end up in DMA operations starting from a misaligned address. This seems fatal for the HW if DRE (Data Realignment Engine) is not enabled. This patch eventually adjusts the transfer size in order to make sure all operations start from an aligned address.

2019-01-07dmaengine: tegra: avoid overflow of byte trackingBen Dooks
The dma_desc->bytes_transferred counter tracks the number of bytes moved by the DMA channel. This is then used to calculate the information passed back in the in the tegra_dma_tx_status callback, which is usually fine. When the DMA channel is configured as continous, then the bytes_transferred counter will increase over time and eventually overflow to become negative so the residue count will become invalid and the ALSA sound-dma code will report invalid hardware pointer values to the application. This results in some users becoming confused about the playout position and putting audio data in the wrong place. To fix this issue, always ensure the bytes_transferred field is modulo the size of the request. We only do this for the case of the cyclic transfer done ISR as anyone attempting to move 2GiB of DMA data in one transfer is unlikely. Note, we don't fix the issue that we should /never/ transfer a negative number of bytes so we could make those fields unsigned.
