Extend the VRAM setting to Vulkan memory-budget reports for DXVK and D3D12 while preserving real heap capacity and allocation results, removing the hard rejection that caused game crashes in FIT and Discord tests.
On some Adreno devices (the Retroid Pocket Duo) SELinux hides kgsl's sysfs
nodes from apps, so the HUD showed no GPU % and no GPU clock. Devices whose
nodes are readable keep using them; nothing changes there or on GPUs
without kgsl.
Where the nodes are blocked:
- GPU %: a native reader maps kgsl's memstore read-only (any kgsl client
may) and samples the ringbuffer start/end timestamps once a millisecond
while a HUD is shown. That covers all GPU work, Android's own
composition included.
- Backup for GPU %: an implicit Vulkan layer in the guest
(tools/gpuload) and the compositor time their own GPU work with
timestamp queries. It runs until the memstore stamps are seen moving,
and for the whole session if they never move.
- GPU clock: a small GPU job of our own reads the always-on and RBBM
cycle counters (libgpuclock).
The HUD diagnostics export lists which source each GPU value came from.
tools/gpuload/build.sh takes the Vulkan headers from build_local.sh's NDK
first and keeps NDK paths with spaces intact.
