coherence rejected "Intel(R) HD Graphics 400" and "Radeon R9 200
Series" on macOS as a Braswell Atom IGP and a desktop PC card. They are
Firefox's sanitized buckets, not devices: SanitizeRenderer
(FIREFOX_152_0_4_RELEASE) maps an Intel Mac's UHD 630 to the first and
a Radeon Pro 5300M to the second, per Firefox's own TestCiMac and
TestMacAmd. fpgen's pinned model records both from Firefox on macOS at
1.14% each. The rule kept every generated Mac off them, removed 24
real macOS presets in #779 (restored here, 9 + 15), and dropped either
GPU from a caller's Mac preset. ANGLE and llvmpipe stay rejected:
Firefox 152 has no ANGLE-on-Metal path (Bug 2046027 came later).
Intel Macs are now checked as machines instead (intel-mac-hardware),
for every non-Apple GPU on macOS:
- a core count some Intel Mac with that GPU reports. Firefox reports
physical cores where kern.tcsm_available is set and logical ones
otherwise, so either counts: 2-8 physical / 4-16 logical for the
IGP, up to the 2019 Mac Pro for a discrete GPU;
- a screen that is not a notched MacBook's or the 24" iMac's. 45.5% of
fpgen's Firefox macOS screens are one, and the draw already put an
Intel or AMD bucket behind 4.9% of them.
The WebGL draw applies the same check, given the core count. The preset
GPU drop moves next to the WebGL draw, after the host core count and
the display clamp: before, a preset's GPU was judged against cores the
launch then replaced. The TypeScript launcher gets the same changes,
and the goldens cover the new check and the narrowed draws.
