Phoronix: Raspberry Pi V3D Driver Enables Anisotropic Filtering

Back in 2017 the Mesa open-source OpenGL driver for Broadcom VC5 hardware most notably used by the Raspberry Pi 4 aimed to enable anisotropic filtering (AF). However, that patch wasn't fully hooked up correctly and now this past week should be in good shape...

A welcome addition to the driver. I am hoping we see a 4+ version soon with improved performance, even if it's just a 25% boost in clocks. (and I'm not including the Pi 400 here, because that was just the Pi foundation finding a slightly better sweet spot, headroom is still the same) If we can OC to 2.5ghz on the CPU and 1ghz on the GPU, a lot more would become possible.

...Just buy a Rockchip SBC. They use Mali GPUs if they even have one and mainline support is quite good. My RockPi S runs perfectly fine with stock musl based Gentoo and fresh, unmolested kernel.org kernel with no special vendor patches other than their uboot (well, armbian's, dunno exactly) for example and everything I tried works.

That actually sounds pretty nice. I didn't realize they were getting good mainline support now. Many years ago I had a Rockchip device that was stuck on an ancient kernel with some old unmaintained distro as the only option.

There is a "4B+" already, kind of. Newer boards ship with the new chip revision also found in Raspberry Pi 400, and it allows for 20% more CPU clock. (Without "overclocking")

Raspberry Pi 4 is almost three years old now. A 4B+ with slight improvements wouldn't really cut it at this point, we need a more solid upgrade with a newer SoC.

What we actually need is a Raspberry PI with a NVMe port for a boot disk, and some faster NVMe to connect an external Disk-array. Would then make a d*mn nice NAS.

Likewise. It's really a shame how ARMv8 was supposed to fix these stupid custom kernel issues and how long it is taking for that to actually come to fruition.

RK3588 or nothing.
