Since Oracle acquired Sun Microsystems, they have shafted open-source communities. With Solaris/OpenSolaris, they stopped doing future developments in public as open-source, producing the bi-weekly "Nevada" development snapshots, posting details to mailing lists, etc. OpenSolaris proper has been killed off and Solaris moved back within Oracle, as a result, it's been tough to know where the progress is at today. There was a preview of Solaris 11 Express last year and that was the last time it's been highlighted in a major manner since being taken over by Oracle.
Alan Coopersmith, part of the Solaris Engineering Team for X and a long-time Sun employee (also an X.Org Foundation board member), has commented on the "death to old Mesa drivers" discussion. "Absolutely agreed there, but the only working DRM module we ship at the moment is a KMS/DRI2 version of i915, so I have no objections to losing the Mesa support for the DRI1 modules suggested."
Alan's comment is in response to the NetBSD developer saying on the list, "Keeping up with DRM in Linux is hard work. You guys are very active."
The interesting point from Alan's e-mail is that they ship KMS/DRI2 version of the Intel i915 driver. Having Intel kernel mode-setting on Solaris would mean they have ported the core KMS infrastructure and also GEM, the Graphics Execution Manager, as required for Intel graphics memory management within the kernel.
They also don't have the Nouveau or Radeon DRM/KMS drivers ported over to Solaris, which means TTM memory management also likely doesn't exist within the Solaris kernel at this point.
It also wasn't said how up-to-date the Intel DRM port is whether it's something recent with features comparable to the modern Linux kernel Intel DRM and whether it supports Intel Sandy Bridge graphics on Oracle Solaris.
So the Solaris kernel at least has Intel KMS/DRI2 graphics support, but it's too bad that's not the case for the Illumos/OpenSolaris-fork community projects. With FreeBSD now carrying proper ZFS file-system support and D-Trace capabilities within the operating system, is there any Phoronix readers still eager for Oracle Solaris?
