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 - Replace module parameter by sysfs use. - Replace bit fields structure with macros and masks use. - Removed SET() and GET() macros by the writel() and readl(). - Removed some noisy info messages. 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' feedback - Removed "default n" on Kconfig Rework driver accordingly to Krzysztof Wilczyński' feedback - Added some explanatory comments for some steps - Added some bit defines instead of magic numbers V6: Rework driver according to Greg Kroah-Hartman' feedback - Squashed patches 2 and 3 - Removed units (MB/s) on the sys file - Reduced mutex scope on the functions called by sysfs Rework driver accordingly to Krzysztof Wilczyński' feedback - Fix typo "DesignWare" V7: Rework driver according to Greg Kroah-Hartman' feedback - Created a sub device (misc device) that will be associated with the PCI driver - sysfs group is now associated with the misc drivers instead of the PCI driver V8: Rework driver according to Greg Kroah-Hartman' feedback - Added more detail to the version changes on the cover letter - Squashed patches 1 and 2 - Removed struct device from the dw_xdata_pcie structure - Replaced the pci_*() use by dev_*() - Added free call for the misc driver name allocation - Added reference counting - Removed snps_edda_data structure and their usage Rebased patches on top of v5.12-rc4 version Cc: linux-doc@vger.kernel.org Cc: linux-pci@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: Derek Kiernan <derek.kiernan@xilinx.com> Cc: Dragan Cvetic <dragan.cvetic@xilinx.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Krzysztof Wilczyński <kw@linux.com> Gustavo Pimentel (5): misc: Add Synopsys DesignWare xData IP driver 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 FIX 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 | 416 +++++++++++++++++++++++++++ 6 files changed, 520 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 -- 2.7.4
