Lepton's Vulkan driver has no external memory or sync fd extensions,
so the Steam Frame gets a native SteamOS build instead. Its backend is
the PC's: OpenXR creates Dawn's own Vulkan instance and device, and the
eyes are copied into the swapchain on Dawn's queue, with nothing shared
between devices.
- openxr_vulkan_win32 and Aurora's vulkan_win32_interop now compile on
desktop Linux. Dawn links statically there, so the bridge calls the
patched package's hooks directly, and exists only when the package's
aurora-dawn.json declares the Vulkan hook ABI (AuroraDawnProvider
turns AuroraVulkanAbi into AURORA_DAWN_VULKAN_HOOKS); a stock Dawn
keeps the stubs and VR falls back to the desktop.
- openxr_integration.cpp gains a Linux branch: XR_KHR_vulkan_enable2,
the timespec clock, refresh rate, performance level, the Frame
controllers and eye gaze; fragment density maps are requested on
Linux as on the Quest (fdm.cpp and gpu.cpp, AURORA_FDM=0/1 overrides).
- Controller motion uses XR_KHR_convert_timespec_time on any Linux.
- CMake: Vulkan headers are fetched for Linux OpenXR builds, the
headset option is MKW_HEADSET on Android and Linux, and Linux aarch64
builds take MKW_LINUX_CPU (cortex-x4 for the Steam Frame, else native).

- Eyes render under a VK_EXT_fragment_density_map: full rate around each eye's forward direction,
2x2 then 4x4 pixel blocks towards the edges ([vr] foveation = off|low|medium|high, default off).
XR_FB_foveation cannot help here: the runtime's maps only shape passes drawing into its
swapchain, and the eyes reach it through a copy.
- aurora-main/patches/dawn/aurora_fdm.inc: Dawn enables the extension only on request and for
dynamic rendering, flags every render pipeline, and chains an immutable RG8 map into any pass
whose first color attachment is a view bound to one (ABI: include/aurora/dawn_fdm_abi.h).
- android/Build-QuestDawn.ps1 builds the pinned Dawn revision with those patches for arm64
(dawn-build CI flags, protobuf off) into a cached package; Build-Quest.ps1 links it
(-StockDawn opts out) and AuroraDawnProvider.cmake enables the ABI from its manifest.
- lib/gfx/foveation.hpp generates the maps (32 px per texel, densities 255/127/63); an eye is
foveated only when single_pass_eyes draws it in one render pass. Menus never are.
- Live level from the headset panel's VR tab and the launcher; the launch decides whether the
device has maps. debug.wiicompiled.foveation and debug.wiicompiled.fdm for A/B.
- Tests: Foveation cases in gx_fifo_tests, mkw_vr_config_tests. Docs: OPENXR.md, quest-port.md.

Brings in the keyboard/mouse rebinding overhaul (#162), the Kamek
skip-return hook fixes (#182, #218), the exit button and controller LED
fix (#221), the autohide-cursor and mute hotkey fix (#211), the Linux
--sysroot plumbing (#224) and the switch to the theofficialgman
dawn-build fork (#215).
Conflicts resolved to keep the VR integration intact:
- settings_overlay.cpp/.h: kept both new declarations. The controller
rebinding UI takes upstream's click-to-rebind widgets wholesale - our
only edit there was wrapping the combo width in Scaled(), and
upstream's bindingWidth is already font-relative, so the headset
panel still scales. Kept our DrawResolutionMenu() extraction (the VR
panel reuses it) while adopting upstream's DrawExitPrompt() and its
new DrawTopBar() prologue; kept our Diagnostics menu alongside
upstream's exit-button width math. HandleEvents merges both keyboard
paths, with the VR recenter hotkey now guarded by !g_rebind.active so
it cannot fire while a binding is being captured.
- AuroraDawnProvider.cmake: dropped our now-dead Android hash block.
Upstream restructured the pins into an if/elseif chain that already
covers android/aarch64, with the digest for the new dawn-build fork;
our leftover block was unreachable and carried the old encounter
digest.
- Version plumbing (Build-Installer.ps1, Setup.Windows Program.cs and
csproj): kept this fork's own line, which is 0.2.39 and centralised in
Launcher/Directory.Build.props, rather than regressing to upstream's
hardcoded 0.2.32.
Verified: translator 654/654; runtime ctest 14/14 including every VR
test; WiiCompiled and RetroRewind link; aurora gx_fifo_tests 262/263,
the one failure being the TevRegisterLiveness case already documented as
pre-existing on this branch.

previous requirement for ubuntu 24.04+ libstdc++ inherited from dawn prebuilds now dropped to ubuntu 22.04+ libstdc++ like the rest of the prebuilds
also add all architectures to the URL_HASH check since the dawn tag doesn't change but the binaries have
