PM / devfreq: rockchip-dfi: add support for RK3588

2023-10-19T12:21:16Z

Add support for the RK3588 to the driver. The RK3588 has four DDR channels with a register stride of 0x4000 between the channel registers, also it has a DDRMON_CTRL register per channel.

PM / devfreq: rockchip-dfi: Add perf support

2023-10-19T12:13:28Z

The DFI is a unit which is suitable for measuring DDR utilization, but so far it could only be used as an event driver for the DDR frequency scaling driver. This adds perf support to the DFI driver. Usage with the 'perf' tool can look like: perf stat -a -e rockchip_ddr/cycles/,\ rockchip_ddr/read-bytes/,\ rockchip_ddr/write-bytes/,\ rockchip_ddr/bytes/ sleep 1 Performance counter stats for 'system wide': 1582524826 rockchip_ddr/cycles/ 1802.25 MB rockchip_ddr/read-bytes/ 1793.72 MB rockchip_ddr/write-bytes/ 3595.90 MB rockchip_ddr/bytes/ 1.014369709 seconds time elapsed perf support has been tested on a RK3568 and a RK3399, the latter with dual channel DDR.

PM / devfreq: rk3399_dmc,dfi: generalize DDRTYPE defines

2023-10-19T11:39:08Z

The DDRTYPE defines are named to be RK3399 specific, but they can be used for other Rockchip SoCs as well, so replace the RK3399_PMUGRF_ prefix with ROCKCHIP_. They are defined in a SoC specific header file, so when generalizing the prefix also move the new defines to a SoC agnostic header file. While at it use GENMASK to define the DDRTYPE bitfield and give it a name including the full register name.

firmware: tegra: Add suspend hook and reset BPMP IPC early on resume

2023-10-13T12:20:27Z

Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp' to mark if BPMP is suspended. Also, add a 'flags' field in the 'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be set from the Tegra MC driver to signal that the reset of BPMP IPC channels is required before sending MRQ to the BPMP FW. Together both the fields allow us to handle any requests that might be sent too soon as they can cause hang during system resume. One case where we see BPMP requests being sent before the BPMP driver has resumed is the memory bandwidth requests which are triggered by onlining the CPUs during system resume. The CPUs are onlined before the BPMP has resumed and we need to reset the BPMP IPC channels to handle these requests. The additional check for 'flags' is done to avoid any un-intended BPMP IPC reset if the tegra_bpmp_transfer*() API gets called during suspend sequence after the BPMP driver is suspended.
