Re: New RPi-VK-Driver low level driver

Impressive work ! 2 questions though: - is there any chance this work could be used by Igalia to offer a Vulkan support for VC4 alongside their VC6 work in a single driver ? - as not every application supports Vulkan yet, how can Vulkan support can be useful for everyday user experience (I heard abo...

Re: Pi 4 - full specification of VideoCore 6

To be fair ARM based systems never came anywhere near replacing other desktops and the first and last attempt with the Archimedes ended almost three decades ago. Most of the world never heard of them and those that did could not afford them. Like me. Grump. So we can forgive those that never heard ...

Re: Pi 4 USB3 connector soldering

Thanks for your answers. I'm affraid residues was not only made of flux, because they were also bright tiny balls. I (mechanically) cleaned those residues on the 4G and 8G boards (hence the scratch on the 4G board). @Heater : exactly, the ugly blob makes me guess the soldering is not that good and c...

Pi 4 USB3 connector soldering

Hi everyone, Once I received my brand new Pi 4 8GB, I turned it back and was surprised to see how ugly are some solderings of the USB3 connector pins. I cleaned that a bit because there was some soldering residues that was not far for making a bridge between pins. I decided to have a look to my Pi 4...

Re: STICKY: Raspberry Pi OS (64 bit) beta test version feedback

Hi there, Tested out with a spare 3A+ and it's running quite fine so far, despite the low amount of memory (had some "out of memory" with X11 which gave up quickly :mrgreen: ). The question was certainly already asked but is there any way of allocating 100% memory to ARM and 0% to GPU ? It could be ...

Re: Raspberry slow as a snail?

Hi, Try to figure out where the issue is. You tested your hard drive, so it's not there. Did you tested your network link ? According your transfer rates, your Pi interface is likely reduced to 100Mbits, so I suspect something weird there. Try some ethernet testing tools available and let us know th...

Re: Raspberry Pi 4 as live transcoder and streamer feasibility

I'm assuming your phones and tablets don't have gigabit ethernet. Transcoding has two factors, CPU/GPU usage and bandwidth, if you need to create a 3Mb/s encoding you need much more computing power than if you create a 15Mb/s encoding. Plex Media Server usually has good transcoding options but does...
