Phoronix on Linux, Graphics
Coming with Linux 4.5 is an eventful x86 platform drivers update.
The x86 platform driver updates landed today in Linux Git and include a new Intel Telemetry platform device and driver, an Intel Telemetry core driver, an Intel P-Unit Mailbox IPC driver, a new Intel HID event driver for hot keys, and updates to the existing drivers.
Beginning with Skylake and Broxton hardware, Intel began requiring firmware blobs as part of their open-source graphics driver stack. This binary firmware is continuing forward with the next-generation Kabylake processors.
With the in-development Linux 4.5 kernel there is the initial Kabylake support, but that support will be further polished over the next few kernel cycles. Published today was the GuC loading support for Kabylake, The GuC engine is for workload scheduling on parallel graphics engines and is what necessitated the firmware introduction with Skylake and Broxton. So it's not entirely a surprise that there's going to be firmware blobs for Kabylake, it would have been more surprising if they would have dropped it after just one generation.
Sixty-three patches were published on the Mesa mailing list this morning for wiring up the ARB_internalformat_query2 extension as needed by OpenGL 4.3.
Consulting firm Igalia has been working on the ARB_internalformat_query2 support for the Intel i965 DRI driver. These 63 patches posted today under a "request for comments" state implement the support for core Mesa and the Intel i965 back-end.
