IBM and the OpenPOWER Foundation are pushing for a wider + software and hardware ecosystem for POWER8-based systems. + Starting in January 2014, we have been doing bringup work on a + Tyan GN70-BP010 POWER8 server, a quad-core 3 GHz system with a + total of 32 hardware threads.

+ +

Updates since the previous report:

+ +

&os; now boots under a hypervisor with the virtual SCSI + block device, the issue previously preventing this has + been fixed.
The powerpc64 pmap code was rewritten to be more + scalable, as the previous pmap code did not scale beyond a small + number of CPUs.
Initial support for IBM's Vector-Scalar Extensions + (VSX) was added.
The &os; kernel was made completely position + independent for powerpc64, and later powerpc32 as well.

+ + + The &os; Foundation + + + +

Get &os; booting natively, rather than under KVM. This + requires writing OPAL drivers for the various hardware + devices in the system.

+ + + +

Integrate loader(8) with petitboot.
