Enable portability subset physical device enumeration.
Don't use Vulkan 1.1+ logical devices on Vulkan 1.0 instances due to the
VkApplicationInfo::apiVersion specification.
Make sure all extension dependencies are enabled when creating a device.
Prefer exposing feature support over extension support via the device
interface to avoid causing confusion with regard to promoted extensions
(especially those that required some features as extensions, but had those
features made optional when they were promoted).
Allow creating presentation-only devices, not demanding any optional
features beyond the basic Vulkan 1.0, for use cases such as internal tools
or CPU rendering.
Require the independentBlend feature for GPU emulation as working around is
complicated, while support is almost ubiquitous.
Move the graphics system initialization fatal error message to xenia_main
after attempting to initialize all implementations, for automatic fallback
to other implementations in the future.
Log Vulkan driver info.
Improve Vulkan debug message logging, enabled by default.
Refactor code, with simplified logic for enabling extensions and layers.
VS/PS_NUM_REG is 6-bit on Adreno 200, and games aren't seen using the
bit 7 to indicate that no GPRs are used. It's not clear why Freedreno
configures it this way.
Some texture fetch fields were deprecated or moved during the development
of the Xenos, reflect that in the comments.
Add definitions of the registers configuring the conversion of vertex
positions to fixed-point. Although there isn't much that can be done with
it when emulating using PC GPU APIs, there are some places in Xenia that
wrongly (though sometimes deliberately, for results closer to the behavior
of the host GPU) assume that the conversion works like in Direct3D 10+,
however the Xenos supports only up to 4 subpixel bits rather than 8. The
effects of this difference are largely negligible, though.
Also add more detailed info about register references and differences from
other ATI/AMD GPUs for potential future contributors.
- This includes infamous 6000 series crashes and crashes on newer drivers for 7000 and 9000 series
Issue was caused by returning invalid (negative) address from MaxAs opcode.
Currently it is unknown if this behaviour is correct and should be checked on console, so slight graphical issues might be present
- Testing currently doesn't work
- VFS Dump is unused. You can use internal function for it
- Demos are only for fun
- Trace Dump & Trace Viewer (unsure, but ok)
You can re-enable them by changing values: enableTests and enableMiscSubprojects in main premake file.
In the future there should be xb command support to overwrite them
- Fixed size of default font size
- Added logic to not load nullptr texture to prevent unexpected issues
- Commited out some trace viewer UI logic for now. It should be redesigned with tables in mind
- Renamed CommonGPUSetting to GPUSetting
- Removed readback_resolve and memexport from d3d12 exclusive option. In the future it will be available for Vulkan too.
- Removed unused enum class: gpu_cvar
- Removed OS specific code from emulator_window
- Added some fixes introduced by RodoMa92 in PR198
- Lack of AVX2 extension (should be done differently in the future)
- Disable deprecated-volatile warning
- Added missing override in posix EventInfo, ImGui notification class and XContent class
- Removed not used XAudio2.h include in XMP
- Fixed missing switch-case in XObject
- Added fugly template in native_list.h
- Fixed multiple smaller issues
- Adding more information in logs for easier debugging
- XamSetDashContext correction
- XCONFIG_USER_VIDEO_FLAGS reports widescreen when set in config by user
- XCONFIG_SECURED_AV_REGION reports proper values when set in config by user
- Added missing \n
Simplifies emission of the blocks themselves (including inserting blocks
into the function's block list in the correct order), as well as phi after
the branching.
Also fixes 64bpp storing with blending in the fragment shader interlock
render backend implementation (had a typo that caused the high 32 bits to
overwrite the low ones).
C++ relational operators are supposed to raise FE_INVALID if an argument is
NaN, use std::isless/greater[equal] instead where they were easy to locate
(though there are other places possibly, mostly min/max and clamp usage was
checked).
Also fixes a copy-paste error making the CPU shader interpreter execute
MINs as MAXs instead.
Hopefully prevents some potential #1971-like situations.
WAIT_REG_MEM's implementation also allowed the compiler to load the value
only once, which caused an infinite loop with the other changes in the
commit (even in debug builds), so it's now accessed as volatile. Possibly
it would be even better to replace it with some (acquire/release?) atomic
load/store some day at least for the registers actually seen as
participating in those waits.
Also fixes the endianness being handled only on the first wait iteration in
WAIT_REG_MEM.
