| | * | | dmaengine: mv_xor: Add support for IO (PCIe) src/dst areasStefan Roese2016-09-152-1/+101
| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable the access to a specific area, the MVEBU XOR controllers needs to have this area enabled / mapped via an address window. Right now, only the DRAM memory area is enabled via such memory windows. So using this driver to DMA to / from a e.g. PCIe memory region is currently not supported. This patch now adds support for such PCIe / IO regions by checking if the src / dst address is located in an IO memory area in contrast to being located in DRAM. This is done by using the newly introduced MBus function mvebu_mbus_get_io_win_info(). If the src / dst address is located in such an IO area, a new address window is created in the XOR DMA controller. Enabling the controller to access this area.

| | * | | k3dma: Fix memory handling in preparation for cyclic modeJohn Stultz2016-08-311-14/+24

This results in leaking a desc structure every time we start an audio transfer. Thus we must manage it ourselves. The k3dma driver already keeps track of the active and finished descriptors via ds_run and ds_done pointers, so cleanup how we handle those two values, so when we tear down everything in terminate_all, call free_desc on the ds_run and ds_done pointers if they are not null. NOTE: HiKey doesn't use the non-cyclic dma modes, so I'm not been able to test those modes. But with this patch we no longer leak the desc structures.

| | * | | k3dma: Fix occasional DMA ERR issue by using proper dma apiJohn Stultz2016-08-311-8/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After lots of debugging on an occasional DMA ERR issue, I realized that the desc structures which we point the dma hardware are being allocated out of regular memory. This means when we fill the desc structures, that data doesn't always get flushed out to memory by the time we start the dma transfer, resulting in the dma engine getting some null values, resulting in a DMA ERR on the first irq. Thus, this patch adopts mechanism similar to the zx296702_dma of allocating the desc structures from a dma pool, so the memory caching rules are properly set to avoid this issue.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Static analysis showed that unitialized array is being used for compare. At line 850 when a dma_mapping_error() occurs, it jumps to dma_unmap. At this point, dma_srcs has not been initialized. However, the code after dma_unmap label checks dma_srcs for a comparison and thus is comparing to random garbage in the array. Given that when dest_dma is being mapped this is the first instance of mapping DMA memory and failed, there is really nothing to be cleaned up and thus should jump to free_resources label instead.

However, the error was not being passed back to the client when tx_status API is called. Changing the error handling behavior to follow this oder. 1. dmaengine asserts error interrupt 2. Driver receives and mark's the txn as error 3. Driver completes the txn and intimates the client. No further submissions. Drop the locks before calling callback, as subsequent processing by client maybe in callback thread. 4. Client invokes status and you can return error 5. On error, client calls terminate_all. You can reset channel, free all descriptors in the active, pending and completed lists 6. Client prepares new txn and so on. As part of this work, got rid of the reset in the interrupt handler when an error happens and the HW is put into disabled state. The only way to recover is for the client to terminate the channel.
