Revert "Make Mac SystemInfo reflect the currently active GPU on dual GPU machines" This reverts commit 720a8bab0eca86e5b9b8c07c200a217fb2c65755. Reason for revert: <INSERT REASONING HERE> Original change's description: > Make Mac SystemInfo reflect the currently active GPU on dual GPU machines > > Currently, the GetSystemInfo() function (in gpu_info_util/SystemInfo_mac.mm) > on dual GPU Macs always updates the active GPU field of the SystemInfo > instance to the first non-Intel GPU it finds. This change overrides the > activeGPUIndex field of the SystemInfo instance to reflect the current GPU > instead of the non-intel GPU. > > Bug: 985486, 984780, angleproject:3701 > Change-Id: Ia93f38f4a2f7728c05e99c83a940722bd3808766 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1752334 > Commit-Queue: Kenneth Russell <kbr@chromium.org> > Reviewed-by: Zhenyao Mo <zmo@chromium.org> > Reviewed-by: Kenneth Russell <kbr@chromium.org> TBR=zmo@chromium.org,geofflang@chromium.org,kbr@chromium.org,dakshidnani@google.com Change-Id: Iacf4b8433ac1aa4d30c51f08ddfc6489af440cc4 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: 985486, 984780, angleproject:3701 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1757373 Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Commit-Queue: Jonah Ryan-Davis <jonahr@google.com>
