Linux Kernel Patches Posted For The ESWIN EIC7700 SoC + SiFive HiFive Premier P550

([RISC-V] 50 Minutes Ago ESWIN EIC7700 + HiFive Premier P550)


Patches were posted to the Linux Kernel Mailing List this morning for wiring up the ESWIN EIC7700 RISC-V SoC support and the most notable board using this SoC so far, the SiFive HiFive Premier P550.

Pinkesh Vaghela of eInfochips posted the set of patches providing a basic Device Tree for enabling the ESWIN EIC7700 RISC-V SoC and its SiFive P550 quad-core CPU cluster to boot the mainline Linux kernel. Additionally there is the DT for the SiFive HiFive Premier P550 as the first development board making use of the EIC7700. These patches have been boot-tested on the HiFive Premier P550.

For those interested there is [1]the patch series with the DT additions for those wanting to try it out now on a SiFive HiFive Premier P550 to run the upstream Linux kernel. The EIC7700 features four P550 RISC-V cores at 1.4GHz, a DNN accelerator rated for 13.3TOPS @ INT8, up to 32GB of LPDDR4/5 memory support, and other standard features for today's RISC-V SoCs.

In case you missed it, last week I posted our initial review and benchmarks of the [2]SiFive HiFive Premier P550 developer board. Having mainline Linux kernel support for it will make it much more useful in using other Linux distributions outside the confines of Ubuntu.

phoronix

The Magician of the Ivory Tower brought his latest invention for the
master programmer to examine. The magician wheeled a large black box into the
master's office while the master waited in silence.
"This is an integrated, distributed, general-purpose workstation,"
began the magician, "ergonomically designed with a proprietary operating
system, sixth generation languages, and multiple state of the art user
interfaces. It took my assistants several hundred man years to construct.
Is it not amazing?"
The master raised his eyebrows slightly. "It is indeed amazing," he
said.
"Corporate Headquarters has commanded," continued the magician, "that
everyone use this workstation as a platform for new programs. Do you agree
to this?"
"Certainly," replied the master, "I will have it transported to the
data center immediately!" And the magician returned to his tower, well
pleased.
Several days later, a novice wandered into the office of the master
programmer and said, "I cannot find the listing for my new program. Do
you know where it might be?"
"Yes," replied the master, "the listings are stacked on the platform
in the data center."
