Antonio Abbatangelo 27c99af5e3 nv2a: Set unpack alignment on surface upload 2023-01-05 13:22:18 -07:00

Erik Abair f7b2acbb79 nv2a: Ensure SurfaceBinding.size can always fit surface 
It is possible to specify a pitch that is smaller than the native size of a
surface (i.e., `pitch < width * bytes_per_pixel`). On hardware this is handled
gracefully, whereas in xemu it will cause buffer overruns when dealing with
swizzling/unswizzling.

Fixes #1152

[Test](https://github.com/abaire/nxdk_pgraph_tests/blob/main/src/tests/surface_pitch_tests.cpp)
[HW Results](https://github.com/abaire/nxdk_pgraph_tests_golden_results/wiki/Results-Surface_pitch)

Note that xemu's swizzling behavior still does not match HW with this change,
it just prevents the test from crashing.

Erik Abair 5f306e749e nv2a: Apply texture parameters when reusing textures 
Fixes the edge case where a texture is reusable but has modified usage
parameters (e.g., `GL_TEXTURE_WRAP_S`). Prior to this change, texture
parameters would be cached permanently until the texture was recreated.

Fixes #1034

Erik Abair c83b53e09d nv2a: Handles depth borders in 3D bordered textures 
3D textures with texture borders have 4 layers of border on either side of the
content layers in addition to the normal 4 pixel border per layer. This change
handles those extra depth layers in roughly the same way that the per-layer
border texels are handled.

Fixes #1171

Erik Abair 1e221e8da9 nv2a: Fallback to recreating texture on surface size mismatch. 
There is no requirement that a surface and texture using the same VRAM address
match with respect to size (in particular pitch). This change prevents
incorrect reuse of a surface binding in the event that the texture size does
not match.

Fixes #1127

Erik Abair f29c2ff42c nv2a: Handle PVIDEO ds_dx and dt_dy registers 
ds_dx and dt_dy describe how the PVIDEO content should be scaled to fit the
output area. Each is calculated via `((in - 1) << 20) / (out - 1)`, this
commit calculates the full frame scale (in / out) and applies that when
determining the texture coordinates for the overlay.

Erik Abair 9fd957d950 nv2a: Add hack for NV_PVIDEO_SIZE_IN sentinel 2022-07-18 10:59:08 -07:00
Erik Abair a675666051 nv2a: Handle SIZE_IN > SIZE_OUT case 
`NV_PVIDEO_SIZE_IN` is set to 0xFFFFFFFF during initialization and teardown
of the PVIDEO overlay. In some cases this can happen before the overlay is
explicitly stopped, leading to an assert. On hardware SIZE_IN values larger
than SIZE_OUT are capped (content is not scaled).

Fixes #330

Erik Abair d06a0c22f1 nv2a: Fix incorrect use of bytes for GL_UNPACK_ROW_LENGTH 
`GL_UNPACK_ROW_LENGTH` is supposed to set the length in pixels, but the DXT
path is setting it to bytes, causing it to read beyond the end of the texture.
