To help with tuning and diagnostics, expose some performance counters so developers can see some of the adapter state without debugging. You can use Windows in-box tools like perfmon or typeperf to see the values. - dwc_eqos-debug: debug event counts like ISR-handled, ISR-unhandled, DPC-by-type. - dwc_eqos-mac: values of various GMAC registers, mainly the MMC counters. Overview: - Keep a collection of active devices so we can enumerate them if anybody asks to collect performance counters. - Define an ID for each device. Use the device's physical address for this, shifted right by 4 to provide support for 36 bits of physical address. - Change the AXI bus parameters to match the docs. I didn't actually perform any tuning here - I just changed the parameters to match up with what the docs describe and verified that this didn't break anything. - Enable the MMC counters and mask their rollover interrupts. - Implement PCW counter collection. - Run ctrpp on the performance counter manifest during build. - Include the generated resources into the driver during build.
