Any idea how recent the VC4 driver is? Curious about benchmarks / performance of VC4 and no VC4. Ultimately, 4.18 and newer kernels are going to make Pi 3b / 3b+ really rock. Anholt, give us something final-ish please!verkerkbr wrote: ↑Sun Oct 28, 2018 2:24 pmJust tried the Raspex 64 bits ARM version based on Ubuntu Cosmic 1810 running on my RPI 3B+
Kernel version is 4.14.76-V8+
Installed the vc4 OpenGL driver (can be done also with rpi-config).
And can report that this setup works very well and is very fast. Running here for more then 24 hours.
It seems just as fast as a standard Linux PC.

A lot of good support and perf improvements have been added for RPi since kernel 4.14. While some upstream stuff has been back-ported to 4.14 kernel, I am curious if the devs ever considered, if possible, leveraging some of the perf / optimizations being used in Clear Linux?
As a regular reader of Phoronix, I regularly see Clear Linux beating the pants off of many popular distros (https://www.phoronix.com/scan.php?page= ... ling&num=2), (https://www.phoronix.com/scan.php?page= ... inux&num=2). An article discussing how these optimizations are tuned for Intel's architecture but can be extended to other platforms was talked about here: https://www.phoronix.com/scan.php?page= ... erformance
I know that GCC 6.4 was where ARM got a proverbial shot in the arm for perf improvements, but surely there's more blood to be squeezed from the stone? Debian Buster looks like it will be very good for the Pi once it's released next year.
ARMv7 optimized versions of the kernel are already used in Raspbian when an ARMv7 capable CPU is detected. However, most of Raspbian userland is compiled for ARMv6 with the notable exception of some libraries. This is to ensure compatibility of the same SD card across all models of Pi computers in educational contexts where children and teachers are swapping cards between Pi computers on a per user or per project basis. While a fully-optimized ARMv7 distribution will likely be faster, this is a bit off topic for this thread.

Kernel 4.19 works very well, except this problem with the Wifi. Was is missing here ?
