Intel Launches DRM Graphics Driver Changes For Linux 3.18 Kernel


Saturday, September 06, 2014:  Intel has launched some DRM graphics driver changes for Linux 3.18 kernel which will take the exciting experience beyond whatever has already sent into drm-next. Intel has set its foot in the drm-next tree with improved Cherryview support and many other changes too.

This week another patch series has been sent by Intel OTC's Daniel Vetter which also landed into drm-next. The changes, which have been mentioned by Vetter are:

* basic code for execlist. It is the fancy new cmd submission on gen8 (Ben, Oscar Mateo, Thomas Daniel et al)

* removal of the useless usage of console_lock for I915_FBDEV=n (Chris)

* ctx and ppgtt relations can be cleaned up

* ppgtt lifetime handling can also be cleaned up (Michel Thierry)

* various cursor code improvements from Ville

* execbuffer code cleanups and secure batch fixes (Chris)

* prep work for dev -> dev_priv transition (Chris)

* other small improvements

Of all these changes, the execlist work will be quite interesting for Intel's upcoming Broadwell "Gen8" graphics. The other changes are just some clean-up programs and improvements are also of very small scale.
