2023-12-21dmaengine: xilinx: xdma: Fix the count of elapsed periods in cyclic modeMiquel Raynal1-2/+4
Xilinx DMA engine is capable of keeping track of the number of elapsed periods and this is an increasing 32-bit counter which is only reset when turning off the engine. No need to add this value to our local counter.

2023-12-21dmaengine: fix NULL pointer in channel unregistration functionAmelie Delaunay1-0/+3
__dma_async_device_channel_register() can fail. In case of failure, chan->local is freed (with free_percpu()), and chan->local is nullified. When dma_async_device_unregister() is called (because of managed API or intentionally by DMA controller driver), channels are unconditionally unregistered, leading to this NULL pointer: [ 1.318693] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0 [...] [ 1.484499] Call trace: [ 1.486930] device_del+0x40/0x394 [ 1.490314] device_unregister+0x20/0x7c [ 1.494220] __dma_async_device_channel_unregister+0x68/0xc0 Look at dma_async_device_register() function error path, channel device unregistration is done only if chan->local is not NULL.

2023-12-21dmaengine: axi-dmac: Add support for scatter-gather transfersPaul Cercueil1-42/+93
Implement support for scatter-gather transfers. Build a chain of hardware descriptors, each one corresponding to a segment of the transfer, and linked to the next one. The hardware will transfer the chain and only fire interrupts when the whole chain has been transferred. Support for scatter-gather is automatically enabled when the driver detects that the hardware supports it, by writing then reading the AXI_DMAC_REG_SG_ADDRESS register. If not available, the driver will fall back to standard DMA transfers.

Allocate hardware descriptors in the format that the HDL core will be expecting them when the scatter-gather feature is enabled, and use these fields to store the data that was previously stored in the axi_dmac_sg structure. Note that the 'x_len' and 'y_len' fields now contain the transfer length minus one, since that's what the hardware will expect in these fields.

2023-12-21dmaengine: idxd: Remove usage of the deprecated ida_simple_xx() APIChristophe JAILLET1-2/+2
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose. Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. Sothis change allows one more device. MINORMASK is ((1U << MINORBITS) - 1), so allowing MINORMASK as a maximum value makes sense. It is also consistent with other "ida_.*MINORMASK" and "ida_*MINOR()" usages.

2023-12-11dmaengine: dmatest: prevent using swiotlb buffer with nobounce parameterAmelie Delaunay1-1/+16
Source and destination data buffers are allocated with GPF_KERNEL flag. It means that, if the DDR is more than 2GB, buffers can be allocated above the 32-bit addressable space. In this case, and if the dma controller is only 32-bit compatible, swiotlb bounce buffer, located in the 32-bit addressable space, is used and introduces a memcpy. To prevent this extra memcpy, due to swiotlb bounce buffer use because source or destination data buffer is allocated above the 32-bit addressable space, force source and destination data buffers allocation with GPF_DMA instead, when nobounce parameter is true.

For RX channels, REG_BUS_WIDTH seems to default to a value of 0xf00, and macOS preserves the upper bits when setting the configuration in the lower ones. If we reset the upper bits to 0, this causes framing errors on suspend/resume (the data stream "tears" and channels get swapped around). Keeping the upper bits untouched, like the macOS driver does, fixes this issue.

2023-11-24dmaengine: uniphier-xdmac: Convert to platform remove callback returning voidUwe Kleine-König1-6/+11
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). There is an error path that has the above mentioned problem. This patch only adds a more drastic error message. To properly fix it, dmaengine_terminate_sync() must be known to have succeeded (or that it's safe to not call it as other drivers seem to assume).

So move the prototype into linux/kprobes.h. - tracing: Fix to check the tracepoint event and return event at parsing stage. The tracepoint event doesn't support %return but if $retval exists, it will be converted to %return silently.
