This doesn't work for me. You have to also do it for kZygoteProcess.

[dshwang, 2015/08/03 12:51:48]

Why do you think so? Zygote don't need to handle native GpuMemoryBuffer

[spang, 2015/08/03 18:24:51]

Zygote runs this initialization once, and then forks multiple times to create
renderers.

I'm pretty sure if the zygote is enabled, and you only check "kRendererProcess"
here, the code will never run.

At least, that's what I experienced. Have you tried it to see if it runs?

[dshwang, 2015/08/04 13:05:21]

It run well in render process, no matter zygote enabled.
Zygote process gets --type=zygote and Render process gets --type=renderer.
ClientNativePixmapManager instance must be created in only renderer. 
Yes, it works well with zygote process. If allow kZygoteProcess here, zygote
creates ClientNativePixmapManagerTEST instance because we don't pass
"--ozone-platform=gbm" to zygote.
