fpga: add device feature list support Device Feature List (DFL) defines a feature list structure that creates a linked list of feature headers within the MMIO space to provide an extensible way of adding features. This patch introduces a kernel module to provide basic infrastructure to support FPGA devices which implement the Device Feature List. Usually there will be different features and their sub features linked into the DFL. This code provides common APIs for feature enumeration, it creates a container device (FPGA base region), walks through the DFLs and creates platform devices for feature devices (Currently it only supports two different feature devices, FPGA Management Engine (FME) and Port which the Accelerator Function Unit (AFU) connected to). In order to enumerate the DFLs, the common APIs required low level driver to provide necessary enumeration information (e.g. address for each device feature list for given device) and fill it to the dfl_fpga_enum_info data structure. Please refer to below description for APIs added for enumeration. Functions for enumeration information preparation: *dfl_fpga_enum_info_alloc allocate enumeration information data structure. *dfl_fpga_enum_info_add_dfl add a device feature list to dfl_fpga_enum_info data structure. *dfl_fpga_enum_info_free free dfl_fpga_enum_info data structure and related resources. Functions for feature device enumeration: *dfl_fpga_feature_devs_enumerate enumerate feature devices and return container device. *dfl_fpga_feature_devs_remove remove feature devices under given container device.

Device Feature List (DFL) defines a feature list structure that
creates a linked list of feature headers within the MMIO space
to provide an extensible way of adding features for FPGA.
Driver can walk through the feature headers to enumerate feature
devices (e.g. FPGA Management Engine, Port and Accelerator
Function Unit) and their private features for target FPGA devices.

fpga: dfl: fme: add performance reporting support This patch adds support for performance reporting private feature for FPGA Management Engine (FME). Now it supports several different performance counters, including 'basic', 'cache', 'fabric', 'vtd' and 'vtd_sip'. It allows user to use standard linux tools to access these performance counters. e.g. List all events by "perf list" perf list | grep fme dfl_fme0/cache_read_hit/ [Kernel PMU event] dfl_fme0/cache_read_miss/ [Kernel PMU event] ... dfl_fme0/fab_mmio_read/ [Kernel PMU event] dfl_fme0/fab_mmio_write/ [Kernel PMU event] ... dfl_fme0/fab_port_mmio_read,portid=?/ [Kernel PMU event] dfl_fme0/fab_port_mmio_write,portid=?/ [Kernel PMU event] ... dfl_fme0/vtd_port_devtlb_1g_fill,portid=?/ [Kernel PMU event] dfl_fme0/vtd_port_devtlb_2m_fill,portid=?/ [Kernel PMU event] ... dfl_fme0/vtd_sip_iotlb_1g_hit/ [Kernel PMU event] dfl_fme0/vtd_sip_iotlb_1g_miss/ [Kernel PMU event] ... dfl_fme0/clock [Kernel PMU event] ... e.g. check increased counter value after run one application using "perf stat" command. perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_mmio_write/ ./test Performance counter stats for './test': 1 dfl_fme0/fab_mmio_read/ 2 dfl_fme0/fab_mmio_write/ 1.009496520 seconds time elapsed Please note that fabric counters support both fab_* and fab_port_*, but actually they are sharing one set of performance counters in hardware. If user wants to monitor overall data events on fab_* then fab_port_* can't be supported at the same time, see example below: perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_port_mmio_write,portid=0/ Performance counter stats for 'system wide': 0 dfl_fme0/fab_mmio_read/ <not supported> dfl_fme0/fab_port_mmio_write,portid=0/ 2.141064085 seconds time elapsed Signed-off-by: Luwei Kang <luwei.kang@intel.com> Signed-off-by: Xu Yilun <yilun.xu@intel.com> Signed-off-by: Wu Hao <hao.wu@intel.com> Link: https://lore.kernel.org/r/1587949583-12058-3-git-send-email-hao.wu@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
