ROCK 5B Debug Party Invitation
I was planning to monitor this and npu.
Maybe create a very simple monitor (collect relevant info) and draw a chart in png at the final step, thatās the idea.
@tkaiser, i am following up on your findings, If i come up with something useful i push it to github.
i think @icecream95 started to reverse engineer the npu, maybe he can disclose some additional info about his findings.
I havenāt gotten very far with reversing the NPU, currently Iām still focusing on the GPU and itās firmware.
(Iāve found that the MCU in the GPU runs at the same speed as the shader cores, so if anyone has a use for a Cortex-M7 clocked at 1 GHz which can access at least 1 GB of RAM through the GPU MMUā¦)

I think you mean the DMC governor, right? Before we move the PD voltage negotiation to the u-boot, we will have to enable DMC to save power to make sure we have enough power booting to kernel
PD voltage negotiation.
For Radxa (no idea whether theyāre following this thread or just have a party in a hidden Discord channel) the results should be obvious especially when sending out review samples to those clueless YouTube clowns who will share performance numbers at least 10% less of what RK3588 is able to deliver.
We did not send any developer edition to any Youtubers, only developers.
Wow thatās insaneā¦ before this, the only chip with Cortex-M7 with such frequency I have ever seen is NXPās i.mx rt1170.
You might get more power savings by CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE=y (spent a lot of time on this half a decade ago when still contributing to Armbian, ofc the distro then needs to switch back to schedutil or ondemand in a later stage e.g. by configuring cpufrequtils or some radxa-tune-hardware service).
Speaking of schedutil vs. ondemand and I/O performance the choice is rather obvious: https://github.com/radxa/kernel/commit/55f540ce97a3d19330abea8a0afc0052ab2644ef#commitcomment-79484235
I/O performance sucks without either performance or ondemand combined with io_is_busy (and to be honest: Radxaās (lack of) feedback sucks too).
My older script code rotting unmaintained in some Armbian service wonāt do it any more (and they wonāt change anything about it since not giving a sh*t about low-level optimisations).
Yeah, but once you send out review samples IMHO you shouldāve fixed the performance issues. Both.
Currently the only other RK3588(S) vendor affected by trashed memory performance is Firefly. All the others have not discovered/enabled the dmc device-tree node so far.
The following experiment was performed to test the effect of the āperformanceā governor in GPU and npu with the latest radxa kernel settings (ondemand without tkaiserās tweaks) :
the board is idle (no GPU and npu activities):

Got a ~10% boost with sdl2-cam demo and i have the feeling that npu became much more responsive.
glmark2-es-drm and testgles2 are capped at 60 fps and kmscube does not report fps. What would be the best way to measure gpu with a possible gain?
I will test with āperformanceā governor and see what i get.
Applied:
echo 1 > /sys/devices/system/cpu/cpu4/cpufreq/ondemand/io_is_busy
echo 25 > /sys/devices/system/cpu/cpu4/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpu4/cpufreq/ondemand/sampling_down_factor
echo 200000 > /sys/devices/system/cpu/cpu4/cpufreq/ondemand/sampling_rate
echo 1 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/io_is_busy
echo 25 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_down_factor
echo 200000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
Got ~20% boost overall.
From 15 FPS to 18 FPS, again, that depends on object being detected, before i had 20 fps peaks, now 24 fps. I think the bottleneck is on opencv.

Please keep in mind that weāve 3 cpufreq policies on RK3588: 0, 4 and 6. And please also keep in mind that cpufreq is just one piece of the puzzle if the task is bottlenecked by CPU cores (maybe opencv). The scheduler and maybe also IRQ processing is another piece.
So I would suggest to switch to performance for all those tests [1] and then try to pin the CPU relevant stuff to the A76 cores either by prefixing calls with taskset -c 4-7 or using cgroups.
Also interesting how /proc/interrupts looks like prior and after such tests since if thereās an awful lot of IRQs and those remain on cpu0 this is another area of optimisation.
[1] Not just cpufreq governor but all of them. IMO it makes more sense to optimize for performance now and for powersavings later once max performance is known:

For whatever reasons these clocks match the following cpufreq policies:

^CFrom the Cortex-M7 datasheet:
If it can do a gigahertz even at 28nm, then at 8nm it shouldnāt even be a challenge.
Iāve also benchmarked the command-stream interpreter (which is seperate from the MCU), and when using the instructions for loading and storing 64 bytes at a time (similar to AArch32 LDM/STM, but adjusted to work with the 96 available 32-bit registers) it can memcpy at about 310 MB/s. Probably the MCU is faster, but it uses a separate address space so mapping memory is harder.

Well, situation with RK3588 and its much more capable memory controller seems to differ 
Using sbc-benchās -g switch to do consumption measurements with this device: Power monitoring on socket 2 of powerbox-1 (Netio 4KF, FW v3.2.0, XML API v2.4, 233.43V @ 49.98Hz).
Weāre talking about ~1740 mW when clocking the LPDDR4 in idle with 528 MHz vs. ~2420 mW when at 2112 MHz. A whopping 680 mW difference at least on my board with 16GB RAM.
All CPU cores and dmc governor set to powersave (only the mW value at the bottom counts since averaged from a few measurements before):

Edit: corrected values above from 700mW difference to 680mW. And tried to confirm with another PSU (this time 15W RPi USB-C power brick, before some 24W USB PD charger):
-
powersave/ 528 MHz: 35.2Ā°C, idle consumption: 1280mW -
performance/ 2112 MHz: 37.9Ā°C, idle consumption: 1910mW
A 630mW difference this time (the measurements include all losses by PSU and cable between PSU and board and those PSUs might differ in low load situations).
The only thing i did not change was the dmc/governor .
No visible improvement with (maybe 0.5 fps spikes):

1800 2256 2256 2112 0 1000 1000So adjusting the cpufreq settings brought the biggest gain. Still interested in SMP/IRQ affinityā¦ do both interrupts and tasks end up on big cores? Can you please post /proc/interrupts contents after such a test run and check with htop/atop where the tasks run and whether there are CPU bottlenecks present?
This may be a naive question, but what kernel are you using to have access to the dmc governor settings ? I pulled the latest one from yesterday on the radxa github repo and am still not seeing the entry under /sys. Did you change any config ? I would have liked to test here to take measurements as well. The debug/clk entries say Iām at 2112 MHz for the DDR, and idling around 1.6W (mesured at the USB plug).
check:
https://github.com/radxa/kernel/commit/4ce9a743b253c0c344686085213de1c4059b9d59
CONFIG_ARM_ROCKCHIP_DMC_DEVFREQ=y
Thanks! So Iām having the right option:
$ zgrep DMC_DEVFREQ /proc/config.gz
CONFIG_ARM_ROCKCHIP_DMC_DEVFREQ=y
I checked the DTB and found the matching dmc node:
$ dtc -I dtb -O dts < /boot/dtbs/5.10.66-21-rockchip-gbbe5dbfb385d/rockchip/rk3588-rock-5b.dtb
dmc {
compatible = "rockchip,rk3588-dmc";
interrupts = <0x00 0x49 0x04>;
interrupt-names = "complete";
devfreq-events = <0x37>;
clocks = <0x0e 0x04>;
clock-names = "dmc_clk";
operating-points-v2 = <0x38>;
upthreshold = <0x28>;
downdifferential = <0x14>;
system-status-level = <0x01 0x04 0x08 0x08 0x02 0x01 0x10 0x04 0x10000 0x04 0x1000 0x08 0x4000 0x08 0x2000 0x08 0xc00 0x08>;
auto-freq-en = <0x01>;
status = "okay";
center-supply = <0x39>;
mem-supply = <0x3a>;
phandle = <0x1d8>;
};
One possibility could be that Iām running on rock5b-v1.1.dtb instead, as it doesnāt have this entry, but Iām seeing regulator-name āvcc3v3_pcie2x1l2ā which isnāt in that one, so Iām still digging.
Edit: hereās what Iām seeing there:
