What

Texture::DepthCopyFormat decides which guest texture formats a depth-compare sample can be served by copying a pending depth surface (ShaderResources.cpp, depthCopy): R32_SFLOAT maps to D32_SFLOAT, R16_UNORM to D16_UNORM, every other format to VK_FORMAT_UNDEFINED, which keeps the sample on the guest-memory path. DepthCompareCopy reaches the two mapped formats (R32F and R16 unorm) through whole draws; nothing exercises the UNDEFINED default. Add depthCopyFormatTests to agc_driver_graphics_tests: both mappings, and UNDEFINED for R8G8B8A8_UNORM, R16_SFLOAT, R16_UINT, R32_UINT, D32_SFLOAT and UNDEFINED.

The expected values are the function's switch. The test does not change behaviour and passes on main.

Tested

Release build, MinGW-w64, Windows 10 (19045), main 5d9dcc42d plus this commit (2aeb06f36). ctest -R '^agc_driver_graphics$': passed (6.9 s). With the 16-bit expectation changed to D32_SFLOAT the same test fails with "a 16-bit unorm color format did not map to the 16-bit unorm depth format", so the new cases run. tools/check_conventions.py --base upstream/main: all checks passed. The new function needs no Vulkan device; the executable ran against the NVIDIA GeForce RTX 4080 SUPER driver. Linux/lavapipe not tested.

Checklist

• Based on current main; no other open PR implements the same tests (no open PR touches DepthCopyFormat; test(agc): cover the DWORD rounding of guest buffer view ranges #6695 and others edit tests/Graphics.cpp at other places)
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); no stubs added
• No notes, investigation .md files or images added to the repository
• New third-party code is a submodule built from source (none added)
• Generic behaviour, not specific to one title
• Depends on: none
• Unblocks: none (test coverage only)
• GPUs tested: NVIDIA GeForce RTX 4080 SUPER, Windows 10 (19045); Linux and lavapipe not tested
• AI-assisted: yes

@adriadam10 a short request for review of this test-only PR (depthCopyFormatTests in agc_driver_graphics_tests: both mappings of Texture::DepthCopyFormat and its VK_FORMAT_UNDEFINED default, which no test reached; +10/-0, no behavior change). Head 2aeb06f36 is MERGEABLE / CLEAN, the Conventions, Eligibility and Intake checks are green, ctest -R ^agc_driver_graphics$ passes (and fails with a deliberately wrong expectation). #6695 also edits tests/Graphics.cpp at another place.
