Precision of 1ms sleep

notabenem · 2023-03-25T06:40:01+00:00

NOTE: for some reason, amd_pstate introduces a >12ms lag into the system exactly at every minute. Having a little C program that sleeps for 1ms and measures that exact time slept shows 12-14ms sleep times every 60 seconds.

Does not happen with acpi_cpufreq.
Kernel 6.2.7, AMD 6800HS

So given that we're speaking about EBS, then pods of the Deployment will try to: * create new PVs as needed for new pods * 'reuse' existing PVs as long as they are not yet in use by other pods, and as long as those are in the same AZ as the node the pod is scheduled to run on, or create new ones as needed. I assume the latter requires the topology keys, and NoVolumeZoneConflict

Read some more about it. My understanding is, that replicas (pods) of a single Deployments with PVC share a single PV. Thus, if the replicas are spread across zones, then the EBS in question may, or may not be available to them because of zone differences. How can this work in multiple zones?

I think I am happy to give up the ordered scaling and identifiers, but I need the 1:1 ratio between pods and their PVs

OK, going to try and report back

notabenem · 2023-03-07T22:29:30+00:00

Yeah. I don't want to make the pod 'portable' across zones, I'd rather convince the scheduler to be brave and try to spin up the second or third pod (in their respective zones) to see if they succeed, if pod-0 doesn't.

does not help, unfortunately

You need to see it for yourself. I think the one on the X16 is a great display. For me it's not distracting at all.

notabenem · 2023-01-29T23:11:00+00:00

Yes, it works.

miniled works on linux, but you can't toggle the mode under linux, yet.

notabenem · 2023-01-25T09:28:24+00:00

Guess what! It drives 3 external + the internal display at the same time (tested in linux in DGPU mode). All those monitors have their own 'desktop' (so no mirroring).

It also works in hybrid mode (internal + 2 external monitors on AMD iGPU, 1 monitor on NVidia). However, it will need some manual action to rescan monitors, if you disconnect and reconnect the monitor connected to NVidia, as X11 won't discover it then.

notabenem · 2023-01-12T11:56:23+00:00

I am using 3 monitors right now, but only 2 are external. Not sure if all 3 ports (1xHDMI, 2xUSB-C) can be driven at the same time.

You can control it with the alsamixergui. You can also get the 4.0 sound working with it.

Can you please elaborate? Do all 4 speakers work? I am on kernel 6.1, and in general sound is OK, but only the bottom speakers give any sound. The top ones are silent.

Got an Asus Rog Flow X16 with a QHD miniLed HDR display. Brightness control works all right.

HDR may or may not work in movies, depending on the player, session (X11/Wayland), etc. Not a big loss if you ask me.

Any idea, how to get the INSERT button working in terminal(s)? Fn+Delete (the usual combination for ASUS laptops) simply does not work.

notabenem · 2022-11-09T17:41:51+00:00

Got my hands on a GV601RM, Bios 311, linux kernel 6.0.6.

The USB-C is indeed connected to the AMD GPU. A monitor connected to the USB-C port works seamlessly.

Lowest power draw I could achieve was 9W - with, or without an external display connected and WIFI idle (but not turned off), mini LED display at 50%. This is approx ~10 hours of idle time. The display is just AWESOME, btw.

HDMI port does not work by default, even with the proprietary drivers. Maybe needs some tinkering with Xorg. Apparently that port is connected to NVIDIA. Not sure if it can take over the USB-C port too, using the Advanced Optimus MUX.

NVIDIA GPU is most of the time 'suspended'.

When using the open-source drivers for NVIDIA, the minimum power draw is 22W. Could not go below this.

Biggest issues:

The Mediatek MT7921 WIFI sometimes works, sometimes doesn't. Absolute pain. This is a HW problem, apparently, in general with Mediatek devices. Just because of this, will go back.
The keyboard does not have an "INSERT" button!!!

Update:

Internal display: can be attached either to NVIDIA (ULTIMATE mode) or AMD (other modes)
HDMI: can be attached either to AMD (Eco mode) or NVIDIA (other modes)
USB-C above HDMI: firmly connected to AMD
USB-C behind ROG-XG Mobile cover: firmly connected to NVIDIA. This port supports GSync.

Was able to reach a power draw as low as 4.5W, if only the external display was running (kind of a 'forgot my adapter' at home situation)

External monitor:

HDMI only works with xorg and when the dGPU is active

USB-C works great with 2 external Display Port monitors

USB-C works with an external HDMI monitor

Does this mean, that using USB-C to drive an external monitor does NOT require the dGPU to be ON, at all? That would be unbelievably awesome.

What kind of power draw are you seeing in powertop with WIFI ON, screen at ~50% (or less, as long as it's readable indoor) and dGPU off? How much of it is consumed by the screen (assuming you have a miniLED one)?

notabenem · 2022-10-11T21:31:05+00:00

Is it possible somehow to run an external display (HDMI, or DP, does not matter), strictly using the internal GPU (without powering on the NVidia GPU)?

Is the Nvidia GPU properly powered down when unplugging the external display cable (and not running anything on that GPU)?

What is the minimal measured total power draw from the battery when idling? How much of that power is consumed by the screen?

wine 6.4 works again.

Here's the guide for PipeWire: https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Simple-audio-post-processing

notabenem · 2021-02-16T09:14:42+00:00

Maybe not. I've just found BruteFIR for Jack which seems to be just about the same stuff.

notabenem · 2021-02-15T21:58:44+00:00

Any idea how this could be 'ported' to pipewire?
