[PATCH v3 0/3] iio: buffer: Fix DMABUF mapping in some systems

by Nuno Sá via B4 Relay

This series fixes an issue with DMABUF support in the IIO subsystem where the wrong DMA device could be used for buffer mapping operations. This becomes critical on systems like Xilinx/AMD ZynqMP Ultrascale where memory can be mapped above the 32-bit address range. Problem: -------- The current IIO DMABUF implementation assumes it can use the parent device of the IIO device for DMA operations. However, this device may not have the appropriate DMA mask configuration for accessing high memory addresses. On systems where memory is mapped above 32-bits, this leads to the use of bounce buffers through swiotlb, significantly impacting performance. Solution: --------- This series introduces a new .get_dma_dev() callback in the buffer access functions that allows buffer implementations to specify the correct DMA device that should be used for DMABUF operations. The DMA buffer infrastructure implements this callback to return the device that actually owns the DMA channel, ensuring proper memory mapping without bounce buffers. Changes: -------- 1. Add .get_dma_dev() callback to iio_buffer_access_funcs and update core DMABUF code to use it when available 2. Implement the callback in the DMA buffer infrastructure 3. Wire up the callback in the dmaengine buffer implementation This ensures that DMABUF operations use the device with the correct DMA configuration, eliminating unnecessary bounce buffer usage and improving performance on high-memory systems. (AI generated cover. I would not be this formal but I guess is not that bad :)) --- Changes in v3: - Patch 1 * Add a new iio_buffer_get_dma_dev() helper to get the DMA dev. - Link to v2: https://lore.kernel.org/r/20251006-fix-iio-dmabuf-get-dma-device-v2-0-d960b… --- Nuno Sá (3): iio: buffer: support getting dma channel from the buffer iio: buffer-dma: support getting the DMA channel iio: buffer-dmaengine: enable .get_dma_dev() drivers/iio/buffer/industrialio-buffer-dma.c | 6 ++++++ drivers/iio/buffer/industrialio-buffer-dmaengine.c | 2 ++ drivers/iio/industrialio-buffer.c | 21 ++++++++++++++++----- include/linux/iio/buffer-dma.h | 1 + include/linux/iio/buffer_impl.h | 2 ++ 5 files changed, 27 insertions(+), 5 deletions(-) --- base-commit: b9700f87939f0f477e5c00db817f54ab8a97702b change-id: 20250930-fix-iio-dmabuf-get-dma-device-339ac70543db -- Thanks! - Nuno Sá

[PATCH net 2/9] can: gs_usb: gs_make_candev(): populate net_device->dev_port

by Marc Kleine-Budde

From: Celeste Liu <uwu(a)coelacanthus.name> The gs_usb driver supports USB devices with more than 1 CAN channel. In old kernel before 3.15, it uses net_device->dev_id to distinguish different channel in userspace, which was done in commit acff76fa45b4 ("can: gs_usb: gs_make_candev(): set netdev->dev_id"). But since 3.15, the correct way is populating net_device->dev_port. And according to documentation, if network device support multiple interface, lack of net_device->dev_port SHALL be treated as a bug.

[PATCH net 1/9] can: gs_usb: increase max interface to U8_MAX

by Marc Kleine-Budde

From: Celeste Liu <uwu(a)coelacanthus.name> This issue was found by Runcheng Lu when develop HSCanT USB to CAN FD converter[1]. The original developers may have only 3 interfaces device to test so they write 3 here and wait for future change. During the HSCanT development, we actually used 4 interfaces, so the limitation of 3 is not enough now. But just increase one is not future-proofed. Since the channel index type in gs_host_frame is u8, just make canch[] become a flexible array with a u8 index, so it naturally constraint by U8_MAX and avoid statically allocate 256 pointer for every gs_usb device.
