Re: Shouldn't the future versions of Pi support AES acceleration?

The major cost is re-spinning the chip with the crypto extensions enabled. I suspect the die space used is fairly small, but to build a new 2711 variant just to add this would be VERY expensive. So this is not at all likely to happen for the Pi4. Whether it is enabled on future chips used on future...

Re: Shouldn't the future versions of Pi support AES acceleration?

That is daft. Between Linux systems you should use NFS for file sharing. It is more flexible and faster than SMB. The only reason to use CIFS (SMB) is for Windows systems, and they will probably be getting NFS support as standard soon. But almost all GUI operating systems seem to be using SMB by de...

Shouldn't the future versions of Pi support AES acceleration?

A few months ago, I found out that Pi4 does not support AES hardware acceleration, when I tried to use disk encryption. And now I found that Windows network share (SMB) that even most Linux desktops, like Ubuntu, use as the default file sharing method, is using AES. It seems that a lot of thing I tr...

Re: Veracrypt performance benchmark: Pi4 VS 8-year-old Intel

a lot of stuff targeting the pi will build for armv6, so it works on even a pi1 that means ignoring all of the fancy features more modern arm cores added, and makes the performance suffer a lot The installer package has "armhf" in its name. I searched the web and that seems to mean "...

Re: Veracrypt performance benchmark: Pi4 VS 8-year-old Intel

Have you built these bench mark tests with gcc 10.2 and 64bit mode + NEON enabled? I don't know. I used the official latest version of Veracrypt pre-built for Raspberry Pi on their homepage (https://www.veracrypt.fr/en/Downloads.html). It was listed as 32bit, and the Pi OS is 32bit, so I guess it p...

The result looks good. I'm wondering what exactly that Intel CPU is?
E3-1230 V2, 4 cores, 8 threads.

Veracrypt performance benchmark: Pi4 VS 8-year-old Intel

I had expected a better result from Pi4. Yes, I knew that the 8-year-old Intel CPU is a desktop CPU and Pi4 is a mobile CPU, but since a lot of time has been passed and ARM CPU's have improved, my expectation was a little bit high. 8-year-old Intel CPU AES 3.9GB/s (hardware-accelerated AES yes) Came...

Safe using a 12V 80mm PC fan without additional hardware?

I have a spare 80mm PC fan. I like the fan because it is quiet. There seem to be small fans specialised for Pi, but I have a bad memory with small fans (not for Pi); They were very noisy. According to the manufacturer, the fan uses 12V and 0.08+-10%A (that is, 72mA ~ 88mA, I think). Its cable has th...

Ubuntu Mate, 4K only 30fps?

I have tried both the official Ubuntu Mate image and Ubuntu Server + desktopify (mate). The results were the same: if I select 4K resolution, only 30/25/24 Hz are showing in the Refresh rate drop-down list in Monitor Preferences. Why is it so? Is it a hardware limitation, or Mate bug, or is my micro...

Is ReSpeaker 2 the best microphone for cheap voice assistant?

I have been using Google Home Mini, but its AI seems stupid. It annoyingly lacks customisability so I have make some unnecessary efforts to work around it. Also, it has a dumb bug that, even though I have reported it to Google last year, has not been fixed. So, I want to ditch it and create my own f...

Re: Is Pi4 desktop experience supposed to be this bad?

So, you are trying to get a feel for the Pi4 performance on the desktop via VNC? A remote desktop protocol? That will NEVER be a good indicator. There are WAY too many overheads to take in to account. You can ONLY determine suitability as a desktop with a directly attached display. End of. EDIT: Wh...

Re: Is Pi4 desktop experience supposed to be this bad?

Linux has had double buffering issues for ages, so that's nothing new. The result from the lack of it, screen tearing, isn't really a big issue for the vast majority of users. Then, remembering that double buffering eats bandwidth/power consumption, and it takes effort to implement... And I'd guess...

I have never understood this fascination with wiggling Windows around and making them tear. It's purely cosmetic and doesn't affect functionality at all. Tearing during video playback is most important of course, along with scrolling Windows. Note that Firefox is not our recommended browser and doe...

Is Pi4 desktop experience supposed to be this bad?

Finally, I got a micro HDMI adapter and plugged Pi4 to my 4k monitor. I had been using Pi4 without a monitor (VNC). I expected at least the level of smoothness and pleasantness that I had with the cheapest Celeron processor and its integrated graphics on Windows 7 several years ago. But oh, no. Even...

Options for starting Pi4 remotely.

Pi4 seems to be using more than 2W when idling. If I do not need Pi to be running most of the time, and only need it sometimes, wasting 2W+ all the time does not seem very efficient. So, I am looking for a way to start Pi (connected to USB power, having been shut down) remotely. Search results says ...
