The driver configures and enables the Synopsys DesignWare PCIe traffic generator IP inside of prototype Endpoint which will generate upstream and downstream PCIe traffic. This allows to quickly test the PCIe link throughput speed and check is the prototype solution has some limitation or not. Changes: V2: Rework driver according to Greg Kroah-Hartman' feedback V3: Fixed issues detected while running on 64 bits platforms Rebased patches on top of v5.11-rc1 version V4: Rework driver according to Greg Kroah-Hartman' feedback Add the ABI doc related to the sysfs implemented on this driver V5: Rework driver accordingly to Leon Romanovsky's feedback Rework driver accordingly to Krzysztof Wilczyński's feedback Cc: Derek Kiernan Cc: Dragan Cvetic Cc: Arnd Bergmann Cc: Andrew Morton Cc: Greg Kroah-Hartman Cc: Jonathan Corbet Cc: Bjorn Helgaas Cc: linux-pci@vger.kernel.org Cc: linux-doc@vger.kernel.org Cc: linux-kernel@vger.kernel.org Gustavo Pimentel (6): misc: Add Synopsys DesignWare xData IP driver misc: Add Synopsys DesignWare xData IP driver to Makefile misc: Add Synopsys DesignWare xData IP driver to Kconfig Documentation: misc-devices: Add Documentation for dw-xdata-pcie driver MAINTAINERS: Add Synopsys xData IP driver maintainer docs: ABI: Add sysfs documentation interface of dw-xdata-pcie driver Documentation/ABI/testing/sysfs-driver-xdata | 46 ++++ Documentation/misc-devices/dw-xdata-pcie.rst | 40 +++ MAINTAINERS | 7 + drivers/misc/Kconfig | 10 + drivers/misc/Makefile | 1 + drivers/misc/dw-xdata-pcie.c | 394 +++++++++++++++++++++++++++ 6 files changed, 498 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-driver-xdata create mode 100644 Documentation/misc-devices/dw-xdata-pcie.rst create mode 100644 drivers/misc/dw-xdata-pcie.c
