Unknown W. Brackets 58a4376998 GPU: Normalize framebuf addresses. 
In VRAM, always store without mirror.  In RAM, always store without
cache/kernel bits.
 2022-10-02 21:28:53 -07:00
Unknown W. Brackets b9b59f7806 GPU: Mask away unused bits in framebuf/zbuf ptr. 
Lower 4 bits are ignored during rendering, and mirrors (even even the 8
bit at the top) are ignored.
 2022-10-02 20:44:35 -07:00
Unknown W. Brackets d16caa71af Vulkan: Add geometry shader ID tracking. 
We're still not generating them, yet.  But this tracks the objects and
IDs through the pipeline.

Henrik Rydgård 7adba20fac Experiment: Generate "Ubershaders" that can handle all lighting configurations 
This drastically reduces the shader compile stutter that happens when a lot of new
light setups are created, like on the first punch in Tekken 6.

There's more stuff that might benefit from being made dynamic like this.
These branches are very cheap on modern GPUs since they're branching on
a uniform variable, so no divergence.

Only tested on Vulkan. I think we'll need to keep the old path too for
gpus like Mali-450...

Henrik Rydgård 287e025978 Minor cleanups around dirtying of render state 2022-09-22 09:12:58 +02:00
Henrik Rydgård ce82fce8de Use subpass dependencies to implement shader framebuffer read in Vulkan. 2022-09-16 19:19:42 +02:00
Henrik Rydgård 694dbe1271 Add ShaderDepalMode enum, use in shader ID. Replaces smoothed bit. 2022-09-11 14:40:01 +02:00
Unknown W. Brackets 542e7aa555 GE Debugger: Add a table of register metadata. 
So far, not used, but indicates info about each GE register.

Henrik Rydgård 8c56abd3dc Remove setting "Disable slower framebuffer effects" 2022-09-03 11:06:43 +02:00
Henrik Rydgård a71a10bb6e Allow signed texture offsets on framebuffers 2022-08-31 01:46:58 +02:00
Henrik Rydgård 7186fc2c17 Offset the draws properly. Now just some texel clamping left to fix 2022-08-31 01:40:53 +02:00
Henrik Rydgård 987bfc79ef Split the framebuffer in Killzone, with a compatibility flag. 
Greatly improves performance.

See issue #6207

Henrik Rydgård 6558bde0f6 Remove SmoothedDepal compat setting, instead detect the ramp directly. 2022-08-22 15:24:41 +02:00
Unknown W. Brackets e374ea6b21 GPU: Restrict mip CLUT enhancement a bit. 
Can't replicate this behavior on a real PSP.

In case a game sets the separate CLUT flag by accident, ignore except
in a safe case that occurs in Misshitsu no Sacrifice.  See #15727.

Henrik Rydgård 131098c4d4 Some enum renaming, move RasterChannel to GPU.h. 2022-08-09 19:58:48 +02:00
Henrik Rydgård 81c36578ca Feature detection fixes 2022-08-06 18:27:03 +02:00
Henrik Rydgård 19931c003f Clean up blit/copy feature detection. Don't need fast GPU flags for these. 2022-08-02 09:53:46 +02:00
Henrik Rydgård f73995b5db Disable texture filtering when drawing color into depth 2022-08-01 14:08:16 +02:00
Henrik Rydgård 90a44579bf Implement color-to-depth for Vulkan, start implementing for D3D11 2022-08-01 11:30:36 +02:00
Henrik Rydgård c158414858 Give the mip bias its own uniform flag. 2022-07-31 10:43:48 +02:00
Henrik Rydgård 2cb9e09ad3 Implement new discovery of a larger CLUT than we thought, plus non-shared CLUTs for 8-bit indices. 
Not sure yet what limitations apply, regarding using it for even more
16-bit colors, etc...
 2022-07-31 10:43:48 +02:00
Henrik Rydgård f061eadc04 Initial implementation of 3D texturing through equal-size mips (see #6357) 
Vulkan-only currently, though all the other backends except ES 2.0
without GL_OES_texture_3d can support it with some work.
 2022-07-31 10:43:47 +02:00
Henrik Rydgård 04a85b1da0 Allows "merging" render targets that overlap on the Y access. Fixes #7295 (Juiced 2) 
To be safe, gating this behind the related AllowLargeFBTextureOffsets,
which is also required for the effect to work.

Additionally, fixes the offset check for X offsets, which I guess is a
very small risk.
 2022-07-24 11:58:07 +02:00
Henrik Rydgård 462972f7ea Add option to redirect blue to alpha if 565 mode is rendered and mask is 0x0FFFFF. 
This is used by several games to render to the alpha channel of RGBA4444
images, which cannot normally be done directly on the PSP.

Can be used as a far more efficient replacement for
ReinterpretFramebuffers/ShaderColorBitmask

Henrik Rydgård 7be86264d0 Move framebufFormat to gstate_c, so we can override it 2022-04-30 18:16:09 +02:00
Unknown W. Brackets 2479d52202 Global: Reduce includes of common headers. 
In many places, string, map, or Common.h were included but not needed.
 2022-01-30 16:35:33 -08:00
Unknown W. Brackets 8efb99801e GPU: Log and report when region1 is non-zero. 2022-01-23 19:38:51 -08:00
Unknown W. Brackets 2797e035df softgpu: Precompute lighting parameters. 
In many cases, games use lighting just for diffuse or something, this
helps skip what's not needed too.  Good improvement in a scene from a
Naruto game.
 2022-01-16 11:27:53 -08:00
Unknown W. Brackets c0e85e6170 softgpu: Move texenv color into sampler state. 2022-01-15 17:52:40 -08:00
Unknown W. Brackets 60bd25582c Vulkan: Remove wide line handling. 
No longer used, since we convert lines to triangles now.
 2021-10-31 14:47:21 -07:00
Unknown W. Brackets 33598f2e75 GPU: Support clip and cull distances separately. 
Older GL devices, and it seems Apple devices, may not support cull.
 2021-10-12 20:34:44 -07:00
Unknown W. Brackets 7b00c4a572 GPU: Move Z/W equal hack to bugs from supports. 
It's really a bug (might even ideally cap the version?), and we already
have other bugs handled the same way.
 2021-10-12 20:34:44 -07:00
Unknown W. Brackets 2271b41d07 Vulkan: Use clip distance only if supported. 2021-10-12 20:34:42 -07:00
Henrik Rydgård 559ccd9f33 Minor cleanups 2020-12-14 20:06:06 +01:00
Henrik Rydgård 32c9728c0c Some cleanups in GL feature and shader language detection. 
Gets rid of many wrong or bad checks for IsCoreContext.
 2020-12-14 19:46:11 +01:00
Henrik Rydgård f3ebd6553d Turn off vertex range culling in bezier/spline calls. 
When we do lower res tess than the real PSP, we cant trust the game to not cause range culling to kick in.

Fixes #11692
 2020-12-13 16:04:16 +01:00
Henrik Rydgård 575ae376a9 Don't try to texture from depth if not supported by backend. Works around #13621 2020-11-10 23:36:33 +01:00
Henrik Rydgård 3d289594f9 ShaderBlend and FramebufferRead are separate concepts. Reflect that in naming. 
The former has forms that don't need to read the framebuffer.

This exposes that some logic is wrong...
 2020-11-08 12:54:05 +01:00
Henrik Rydgård 7b2236778b Remove remnants of an old, no longer applicable readback optimization 2020-11-05 14:38:20 +01:00
Henrik Rydgård dc0f7ca8ee VK: Copy depth buffer if we can't blit. Some GPUs can't blit to depth. 
Fixes some recent issues with Intel GPUs on Vulkan.
 2020-10-11 10:57:35 +02:00
Henrik Rydgård d0f7b1e30f Make the implementations of CopyFramebufferDepth more similar. 
Also avoid matching framebuffers with bad z for copies.
 2020-09-17 20:52:45 +02:00
Henrik Rydgård 181ddd842a Unify some GPU_SUPPORT* bits 2020-09-17 20:52:32 +02:00
Henrik Rydgård 1b3413945b Some header include cleanup 2020-09-16 09:20:41 +02:00
Henrik Rydgård eadd3c5785 Remove the LARGE_VIEWPORTS separate path. The fewer paths the better, all need to work anyway. 
Required fixing a bug in ShaderUniforms.cpp (used by D3D11 and Vulkan,
the two backends that previously exposed LARGE_VIEWPORTS).
 2020-08-05 19:03:08 +02:00
Henrik Rydgård 70ec327b40 Vulkan: Slim down and rename the Mali hack. 2019-09-09 00:43:31 +02:00
Henrik Rydgård f76adfd760 Vulkan ARM mali Z hack: Modify the matrix instead of the shader. 2019-09-09 00:09:57 +02:00
Henrik Rydgård 0462c01228 Workaround ARM Mali depth hardware bug. Fixes #11937 
When triangles coincide with the Z=1 plane in specific ways, triggered
by Burnout Legends' sky for example, the depth buffer gets corrupted.

This is worked around here by slightly rescaling Z. This type of
workaround is recommended by ARM driver engineers.

Ugly but what can you do when the hardware is bugged. I've done quick
tests on a number of games with no issues.
 2019-09-08 23:44:26 +02:00
Unknown W. Brackets 7412e13767 SoftGPU: Implement dithering. 
Note: it applies even in 8888, so it can be used as a slight brightness
adjustment.
