A RISC-V chip is now available in the form of SiFive’s Freedom E310 (Fig. 1). The Freedom E310 is a microcontroller with a 32-bit RV32IMAC architecture. The RV32IMAC designation is an abbreviation for the standard RISC-V features including 32-bit support (RV32), integer support (I), hardware integer multiplication and division (M), atomic real-time instructions (A), and support for the 32-bit and compact (C) 16-bit instruction set. The chip has 16 32-bit registers and no hardware stack. As with many RISC systems, it uses a jump and link (JAL) instruction to save a return address in a register.
This is a minor maintenance release in the 4MLinux STABLE channel. The release ships with the Linux kernel 4.4.34, which restores PAE support that "magically" disappeared in 4MLinux 20.0 (sorry :-). Additionally, some popular programs (Double Commander, Dropbox, Firefox, Java RE, Opera, PeaZip, Thunderbird, Wine) have been updated, too.
Refracta 8.0 Is a Pint-Sized Powerhouse
Refracta is a somewhat obscure Linux distribution that offers exceptional functionality and stability.
Obscurity is not always a bad thing when it comes to Linux distros. You can find some very worthwhile alternatives to your current operating system. Refracta is a big surprise in a small package.
Many look-alike desktop distros are difficult to distinguish from run-of-the-mill garden varieties. Others offer new adopters something unique that makes using them fun and productive.
Refracta is one of the few full-service Linux distros that makes an easy and more convenient replacement for pocket Linux options such as Puppy Linux. Not all Linux distros that install to a USB drive -- and have the ability to save files and system settings in a persistent mode -- work equally well.
Clear Linux With Mesa 13 Is A Strong Match For Intel Linux Performance
When benchmarking Intel's Clear Linux distribution earlier this year we found its Intel graphics performance to be quite good and slightly faster than other Linux distributions even when Clear was using an older version of Mesa. Now with Clear Linux having switched to Mesa 13, I decided to run some fresh Intel OpenGL benchmarks on it compared to other distributions.
