[PATCH 14/14] usb: dwc2: host: use kmem cache to allocate descriptors

Kmem caches help to get correct boundary for descriptor buffers which need to be 512 bytes aligned for dwc2 controller. Two kmem caches are needed for generic descriptors and for hs isochronous descriptors which doesn't have same size. Signed-off-by: Gregory Herrero --- drivers/usb/dwc2/core.h

[PATCH 01/14] usb: dwc2: host: ensure filling of isoc desc is correctly done

Increment qtd->isoc_frame_index_last before testing it, else below check will never be true and IOC (Interrupt On Complete) bit for last frame will never be set in descriptor status. /* Set IOC for each descriptor corresponding to last frame of URB */ if (qtd->isoc_frame_index_last == qtd->urb

[PATCH 12/14] usb: dwc2: host: avoid usage of dma_alloc_coherent with irqs disabled

Use Streaming DMA mappings to handle cache coherency of frame list and descriptor list. Cache are always flushed before controller access it or before cpu access it. Signed-off-by: Gregory Herrero --- drivers/usb/dwc2/core.c | 9 drivers/usb/dwc2/core.h | 2 + drivers/usb/dwc2/h

[PATCH 02/14] usb: dwc2: host: set active bit in isochronous descriptors

Active bit must be enabled in all scheduled descriptors. Else transfer never start. Remove previous code which was not correctly configuring descriptors. Active bit was set before calling dwc2_fill_host_isoc_dma_desc() which is erasing dma_desc->status. Signed-off-by: Gregory Herrero --- drivers

[PATCH 00/14] usb: dwc2: descriptor dma mode bug fixes

Hi, This patchset contains bug fixes for host descriptor dma mode. Descriptor dma mode can't be used as the default mode since controller does not support split transfers in this mode. So we add a new configuration parameter which allows descriptor dma mode to be enabled for full-speed devices on

[PATCH 11/14] usb: dwc2: host: enable descriptor dma for fs devices

From: Mian Yousaf Kaukab As descriptor dma mode does not support split transfers, it can't be enabled for high speed devices. Add a core parameter to enable it for full speed devices. Ensure frame list and descriptor list are correctly freed during disconnect. Signed-off-by: Mian Yousaf Kaukab

[PATCH 03/14] usb: dwc2: host: rework isochronous halt path

[PATCH 04/14] usb: dwc2: host: fix use of qtd after free in desc dma mode

When completing non isoc xfer, dwc2_complete_non_isoc_xfer_ddma() is relying on qtd->n_desc to process the corresponding number of descriptors. During the processing of these descriptors, qtd could be unlinked and freed if xfer is done and urb is no more in progress. In this case, dwc2_complete_n

Isochronous descriptor is currently programmed for the frame after the last descriptor was programmed.
