Patch series uses dma engine APIs in pci-epf-test to transfer data using DMA. It also adds an option "-d" in pcitest for the user to indicate whether DMA has to be used for data transfer. This also prints throughput information for data transfer. Changes from v2: *) Removed use of "bool" in uapi/linux/pcitest.h as that seems to fail for certain configs (header should be self contained). It was failing for "x86_64 allmodconfig". *) Modified function comments added before DMA transfer functions. Changes from v1: *) Fixed some of the function names from pci_epf_* to pci_epf_test_* since the DMA support is now been moved to pci-epf-test.c Kishon Vijay Abraham I (5): PCI: endpoint: functions/pci-epf-test: Add DMA support to transfer data PCI: endpoint: functions/pci-epf-test: Print throughput information misc: pci_endpoint_test: Use streaming DMA APIs for buffer allocation tools: PCI: Add 'd' command line option to support DMA misc: pci_endpoint_test: Add support to get DMA option from userspace drivers/misc/pci_endpoint_test.c | 165 ++++++++++-- drivers/pci/endpoint/functions/pci-epf-test.c | 253 +++++++++++++++++- include/uapi/linux/pcitest.h | 7 + tools/pci/pcitest.c | 23 +- 4 files changed, 417 insertions(+), 31 deletions(-) -- 2.17.1
