Just ahead of the weekend, Intel has published a new set of patches up for testing that are expected to then be merged to DRM-Next for Linux 4.15.

This latest kernel graphics i915 DRM driver code changes the following:

- lib/scatterlist updates, use for userptr allocations (Tvrtko)
- Fixed point wrapper cleanup (Mahesh)
- Gen9+ transition watermarks, watermark optimization and fixes (Mahesh)
- Display IPC (Isochronous Priority Control) support (Mahesh)
- GEM workaround fixes (Oscar)
- GVT: PCI config sanitize series (Changbin)
- GVT: Workload submission error handling series (Fred)
- PSR fixes and refactoring (Rodrigo)
- HWSP based optimizations (Chris)
- Private PAT management (Zhi)
- IRQ handling fixes and refactoring (Ville)
- Module parameter refactoring and variable name clash fix (Michal)
- Execlist refactoring, incomplete request unwinding on reset (Chris)
- GuC scheduling improvements (Michal)
- OA updates (Lionel)
- Coffeelake out of alpha support (Rodrigo)
- seqno fixes (Chris)
- Execlist refactoring (Mika)
- DP and DP MST cleanups (Dhinakaran)
- Cannonlake slice/sublice config (Ben)
- Numerous fixes all around (Everyone)

Great to see the continued fixes and low-level code improvements along with some optimizations, more Cannonlake and Coffeelake tweaking, some GVT graphics virtualization work, GuC scheduling improvements, and more. It's outlined via the mailing list while this code can be fetched via the drm-intel Git repository.

This is on top of other Intel i915 code already queued in DRM-Next for the Linux 4.15 cycle.
