Message-ID: <1886728731.2440253.1483384233052.JavaMail.zimbra@unseen.is> Hi Kernel Devs! I'm interested in adding SPARCv9 support to the kernel? Because of the SMP optimization of Dragonfly, I want to run this operating system on top of a new many-core chip I'm designing. The design is derived from a framework called OpenPiton, and they've already adapted the Linux kernel to suit their needs.

The drm/i915 driver in master is currently based on Linux 4.6 + a few fixes from 4.7. Can you check if Linux 4.6 itself works fine on your hardware ? this should reduce the search domain a bit. -- Francois Tigeot From michael.brodeur at unseen.is Mon Jan 2 11:10:33 2017 From: michael.brodeur at unseen.is (michael.brodeur at unseen.is) Date: Mon, 2 Jan 2017 19:10:33 +0000 (GMT) Subject: Add SPARCv9 support?
