Hi All, Based on Marcs series here are some more fixes to the cache handling for USB/ehci. As Marc already mentioned we have to make sure that buffers which are used for DMA are cacheline aligned, otherwise we risk corrupting data around the buffers. Sascha ---------------------------------------------------------------- Sascha Hauer (9): USB core: allocate setup_packet using dma_alloc USB core: device descriptor using dma_alloc USB core: Allocate tmpbuf using dma_alloc USB ehci: Use dma coherent buffers for qh/qtd USB ehci: put fields of struct qTD directly into struct QH USB storage: use dma_alloc where appropriate block: use dma_alloc to allocate buffers partition: Use dma_alloc for allocating buffers USB ehci: rework cache handling common/block.c | 7 +-- common/partitions.c | 5 +- drivers/usb/core/usb.c | 100 ++++++++++++++++++++---------------- drivers/usb/host/ehci-hcd.c | 108 ++++++++++++--------------------------- drivers/usb/host/ehci.h | 10 +++- drivers/usb/storage/transport.c | 11 ++-- include/usb/usb.h | 3 +- 7 files changed, 115 insertions(+), 129 deletions(-) _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
