Preload graphics drivers in Mac WebProcess
https://bugs.webkit.org/show_bug.cgi?id=215183
Reviewed by Darin Adler.
Source/WebCore:
In newer versions of Mac OS, graphics drivers are no longer part of the shared cache due to
size restrictions. This can cause first render to be blocked by ~10 ms when we dlopen those
drivers. To work around this, we preload the drivers when prewarming the WebProcess.
* page/ProcessWarming.cpp:
(WebCore::ProcessWarming::prewarmGlobally):
Source/WTF:
Enable GPU driver preheating in versions of the OS that might not have the drivers in the dyld
shared cache due to size restrictions.
* wtf/PlatformEnableCocoa.h:
