The layer stride provided by the depth register in Maxwell3D needs to be shifted by 2, this caused the stride to be 1/4th of what it needed to be resulting in OOB access.
When calculating mip-level dimensions in terms of GOBs, they need to be divided by 2 while rounding upwards rather than downwards. This fixes corrupted textures and OOB access on lower mip levels across a substantial amount of titles, reducing arbitrary crashes as a result.
The default `compiler_check` strategy used by ccache was causing a 0% hit rate, as it was using the compiler's "modified time" as part of the hash. Since the script installs dependencies from scratch for every run, mtime was always different, causing different hashes even when source files were unchanged. To avoid this, use the NDK version as part of the hash instead.
This JSON file is generated for any APK builds, it's entirely unnecessary to commit to the repository and has no relevance outside of the local context therefore has been added to `.gitignore`.

Since we align up when allocating, not doing so when deallocating would result in a gradual buildup of boundary pages that eventually fill the whole address space.
These are about 100x as expensive on adreno than nvidia due to the lack of a dedicated instruction, since some games work fine without them add a hack to disable them.
The vulkan guest driver doesn't expect a 0xB return code from SyncptEventWait, even though this is valid when an event is being signalled. Just ignore the intermediate state instead as doing so avoids races without causing any more.
The excessive blocking caused by initial compilation happening async to the guest caused issues in some cases, now we have a Vulkan pipeline cache to speed it up we can wait for a full compile before launch without too many issues.
By only using what we need, and mirroring the descriptor structs to allow for much tighter packing (while keeping the same member names) we can reduce pipeline memory to about 1/3 of what it was before.
