[igt-dev] [PATCH i-g-t v2 0/7] Make gpgpu fill tests libdrm independent

[Zbigniew Kempczyński]

I've introduced intel_bb which is very simplified version of libdrm
powered intel_batchbuffer. Currently it supports simple relocation
but it is enough to cover all gpgpu fill needs. Other (fenced) 
relocation will be added when I will have to face with such pipelines /
batchbuffers.

I think there're two possibilities - iterate until functions with 
suffix "_v2" will be ready to be replaced older libdrm versions or when 
patch will be mature enough to merge and add other gens one by one
with final replacement of "_v2" to "" on the end. I'm looking forward
review comments and suggestions. 

v2: changes according to the review:
    - make intel_bb api more consistent and universal
    - add intel_bb api documentation
    - add alignment field in buf_ops buffer initalization for linear
      buffers
