Debugging options for the DMA engine subsystem This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA engine subsystem, I got tired of editing the Makefile manually each time I want to debug things in here, modelled this on the debug switches for other subsystems and works like a charm when working on our DMA engines.

dma: acpi-dma: introduce ACPI DMA helpers There is a new generic API to get a DMA channel for a slave device (commit 9a6cecc8 "dmaengine: add helper function to request a slave DMA channel"). In similar fashion to the DT case (commit aa3da644 "of: Add generic device tree DMA helpers") we introduce helpers to the DMAC drivers which are enumerated by ACPI. The proposed extension provides the following API calls: acpi_dma_controller_register(), devm_acpi_dma_controller_register() acpi_dma_controller_free(), devm_acpi_dma_controller_free() acpi_dma_simple_xlate() acpi_dma_request_slave_chan_by_index() acpi_dma_request_slave_chan_by_name() The first two should be used, for example, at probe() and remove() of the corresponding DMAC driver. At the register stage the DMAC driver supplies a custom xlate() function to translate a struct dma_spec into struct dma_chan. Accordingly to the ACPI Fixed DMA resource specification the only two pieces of information the slave device has are the channel id and the request line (slave id). Those two are represented by struct dma_spec. The acpi_dma_request_slave_chan_by_index() provides access to the specifix FixedDMA resource by its index. Whereas dma_request_slave_channel() takes a string parameter to identify the DMA resources required by the slave device. To make a slave device driver work with both DeviceTree and ACPI enumeration a simple convention is established: "tx" corresponds to the index 0 and "rx" to the index 1. In case of robust configuration the slave device driver unfortunately needs to call acpi_dma_request_slave_chan_by_index() directly. Additionally the patch provides "managed" version of the register/free pair i.e. devm_acpi_dma_controller_register() and devm_acpi_dma_controller_free(). Usually, the driver uses only devm_acpi_dma_controller_register().

#dmatest
dmatest: Simple DMA memcpy test client This client tests DMA memcpy using various lengths and various offsets into the source and destination buffers. It will initialize both buffers with a repeatable pattern and verify that the DMA engine copies the requested region and nothing more. It will also verify that the bytes aren't swapped around, and that the source buffer isn't modified. The dmatest module can be configured to test a specific device, a specific channel. It can also test multiple channels at the same time, and it can start multiple threads competing for the same channel. Changes since v2: * Support testing multiple channels at the same time * Support testing with multiple threads competing for the same channel * Use counting test patterns in order to catch byte ordering issues Changes since v1: * Remove extra dashes around "help" * Remove "default n" from Kconfig * Turn TEST_BUF_SIZE into a module parameter * Return DMA_NAK instead of DMA_DUP * Print unhandled events * Support testing specific channels and devices * Move to the end of the Makefile Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on at91sam9rl chip. It will be used on other products in the future. This first release covers only the memory-to-memory tranfer type. This is the only tranfer type supported by this chip. On other products, it will be used also for peripheral DMA transfer (slave API support to come). I used dmatest client without problem in different configurations to test it.

dmaengine: mxs-dma: add dma support for i.MX23/28 This patch adds dma support for Freescale MXS-based SoC i.MX23/28, including apbh-dma and apbx-dma. * apbh-dma and apbx-dma are supported in the driver as two mxs-dma instances. * apbh-dma is different between mx23 and mx28, hardware version register is used to differentiate. * mxs-dma supports pio function besides data transfer. The driver uses dma_data_direction DMA_NONE to identify the pio mode, and steals sgl and sg_len to get pio words and numbers from clients. * mxs dmaengine has some very specific features, like sense function and the special NAND support (nand_lock, nand_wait4ready). These are too specific to implemented in generic dmaengine driver. * The driver refers to imx-sdma and only a single descriptor is statically assigned to each channel.

dmaengine: pxa: add pxa dmaengine driver This is a new driver for pxa SoCs, which is also compatible with the former mmp_pdma. The rationale behind a new driver (as opposed to incremental patching) was : - the new driver relies on virt-dma, which obsoletes all the internal structures of mmp_pdma (sw_desc, hw_desc, ...), and by consequence all the functions - mmp_pdma allocates dma coherent descriptors containing not only hardware descriptors but linked list information The new driver only puts the dma hardware descriptors (ie. 4 u32) into the dma pool allocated memory. This changes completely the way descriptors are handled - the architecture behind the interrupt/tasklet management was rewritten to be more conforming to virt-dma - the buffers alignment is handled differently The former driver assumed that the DMA channel stopped between each descriptor. The new one chains descriptors to let the channel running. This is a necessary guarantee for real-time high bandwidth usecases such as video capture on "old" architectures such as pxa. - hot chaining / cold chaining / no chaining Whenever possible, submitting a descriptor "hot chains" it to a running channel. There is still no guarantee that the descriptor will be issued, as the channel might be stopped just before the descriptor is submitted. Yet this allows to submit several video buffers, and resubmit a buffer while another is under handling. As before, dma_async_issue_pending() is the only guarantee to have all the buffers issued. When an alignment issue is detected (ie. one address in a descriptor is not a multiple of 8), if the already running channel is in "aligned mode", the channel will stop, and restarted in "misaligned mode" to finished the issued list. - descriptors reusing A submitted, issued and completed descriptor can be reused, ie resubmitted if it was prepared with the proper flag (DMA_PREP_ACK). Only a channel resources release will in this case release that buffer. This allows a rolling ring of buffers to be reused, where there are several thousands of hardware descriptors used (video buffer for example). Additionally, a set of more casual features is introduced : - debugging traces - lockless way to know if a descriptor is terminated or not The driver was tested on zylonite board (pxa3xx) and mioa701 (pxa27x), with dmatest, pxa_camera and pxamci.

dmaengine: add driver for Samsung s3c24xx SoCs This adds a new driver to support the s3c24xx dma using the dmaengine and makes the old one in mach-s3c24xx obsolete in the long run. Conceptually the s3c24xx-dma feels like a distant relative of the pl08x with numerous virtual channels being mapped to a lot less physical ones. The driver therefore borrows a lot from the amba-pl08x driver in this regard. Functionality-wise the driver gains a memcpy ability in addition to the slave_sg one. The driver supports both the method for requesting the peripheral used by SoCs before the S3C2443 and the different method for S3C2443 and later. On earlier SoCs the hardware channels usable for specific peripherals is constrainted while on later SoCs all channels can be used for any peripheral. Tested on a s3c2416-based board, memcpy using the dmatest module and slave_sg partially using the spi-s3c64xx driver.
