2021-11-22dmaengine: dw-axi-dmac: Fix uninitialized variable in ↵Tim Gardner
axi_chan_block_xfer_start() Coverity complains of an uninitialized variable: 5. uninit_use_in_call: Using uninitialized value config.dst_per when calling axi_chan_config_write. [show details] 6. uninit_use_in_call: Using uninitialized value config.hs_sel_src when calling axi_chan_config_write. [show details] CID 121164 (#1-3 of 3): Uninitialized scalar variable (UNINIT) 7. uninit_use_in_call: Using uninitialized value config.src_per when calling axi_chan_config_write. [show details] 418 axi_chan_config_write(chan, &config); Fix this by initializing the structure to 0 which should at least be benign in axi_chan_config_write(). Also fix what looks like a cut-n-paste error when initializing config.hs_sel_dst.

2021-02-01dmaengine: dw-axi-dmac: Virtually split the linked-listSia Jee Heng
AxiDMA driver exposed the dma_set_max_seg_size() to the DMAENGINE. It shall helps the DMA clients to create size-optimized linked-list for the controller. However, there are certain situations where DMA client might not be abled to benefit from the dma_get_max_seg_size() if the segment size can't meet the nature of the DMA client's operation. In the case of ALSA operation, ALSA application and driver expecting to run in a period of larger than 10ms regardless of the bit depth. With this large period, there is a strong request to split the linked-list in the AxiDMA driver.

2019-12-26dmaengine: virt-dma: Add missing lockingSascha Hauer
Originally freeing descriptors was split into a locked and an unlocked part. The locked part in vchan_get_all_descriptors() collected all descriptors on a separate list_head. This was done to allow iterating over that new list in vchan_dma_desc_free_list() without a lock held. This became broken in 13bb26ae8850 ("dmaengine: virt-dma: don't always free descriptor upon completion"). With this commit vchan_dma_desc_free_list() no longer exclusively operates on the separate list, but starts to put descriptors which can be reused back on &vc->desc_allocated. This list operation should have been locked, but wasn't. In the mean time drivers started to call vchan_dma_desc_free_list() with their lock held so that we now have the situation that vchan_dma_desc_free_list() is called locked from some drivers and unlocked from others. To clean this up we have to do two things: 1. Add missing locking in vchan_dma_desc_free_list() 2. Make sure drivers call vchan_dma_desc_free_list() unlocked This needs to be done atomically, so in this patch the locking is added and all drivers are fixed.
