GameNative testing builds based on exact upstream FEXCore 2609 commit 395b132f346b1a45def246d10c52245edba1ef02, with the bounded disk-cache patch applied reproducibly by pipeline commit 98cf820836ca5f15b3fd1552c9985a24604edf8f.

Common tuning in both packages:

  • Release / O3 / NDEBUG.
  • Conservative FEX TUNE_ARCH=generic ISA baseline.
  • TUNE_CPU=none plus -mtune=cortex-a76 scheduling optimization, so no newer ARM ISA extensions are introduced by the mobile tune.
  • Assertions/tests/ccache off and LTO off. ARM64EC LTO remains excluded because the current LLVM ARM64EC LTO path is broken.
  • PGO is not claimed because no representative GameNative workload profile is baked into these binaries.

Bounded-cache behavior:

  • The limit covers the total writable cache database plus its index.
  • Existing entries remain readable at the limit; new entries are simply not admitted.
  • No live eviction/compaction is attempted in this 2609 patch.
  • FEX_DISKCACHEMAXSIZEMB=0 means unlimited, preserving upstream behavior.
  • Both FEX_DISKCACHE and FEX_DISKCACHEMAXSIZEMB remain normal FEX runtime configuration/environment controls.

Candidates:

  • FEXCore-2609-GameNative-O3-MobileTune-CacheConfig.wcp — cache off by default and capacity unlimited (0 MiB) by default; enable the cache and set any desired capacity at runtime.
  • FEXCore-2609-GameNative-O3-MobileTune-Cache1GB.wcp — cache on by default with a 1024 MiB total writable limit; both defaults remain runtime-overridable.
