Enable GPU rasterization on Intel GPUs

Project Member Reported by martina....@intel.com, Jun 8 2018

Issue description

Rasterization on Linux and Intel GPUs is currently set to software only. I haven't been able to find the root cause of this - disabling the GPU blacklist doesn't help and I can't find anything relevant in software_rendering_list.json. I tried deleting the items from that list with feature "gpu_rasterization" and it's still not enabled. Forcing it with --enable-gpu-rasterization does work. Could somebody please tell me what decides whether GPU rasterization is enabled?

Tested on 0a850b216acedca65ed6 and 68.0.3423.2.

I don't think it's exclusive to Intel; GPU rasterization has not been enabled by default on any Linux platform. ericrk@ would know for sure.
You're right, it's just Linux that is disabled and doesn't seem to be related to Intel GPUs.
https://cs.chromium.org/chromium/src/gpu/config/gpu_finch_features.cc?q=kDefaultEnableGpuRasterization&sq=package:chromium&dr=CSs&l=20

Modifying this to include Linux will enable rasterization for me without any other modifications or flags.

What is the process for getting it enabled on Linux by default?
Status: Available (was: Untriaged)
ericrk: do we have an open bug for Linux GPU rasterization that this should be duped into?

Regarding getting this enabled, I think we'd need to do some performance and correctness testing across various gpus / drivers and likely determine some whitelist that's acceptable for turning this on.
