Ethan Lee b5624e14ff gpu: Add SDL_PROP_GPU_DEVICE_CREATE_VULKAN_REQUIRE_HARDWARE_ACCELERATION property 2025-11-10 20:20:05 -05:00
Ethan Lee 0b2073d143 gpu: Remove dead code in the Vulkan device ranking system.
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled 
This block was a sloppy way of trying to avoid prioritizing lavapipe over another device, but truthfully the only way to guarantee avoiding CPU drivers is to add a property to allow apps to require hardware acceleration.

Ethan Lee 1b79ba9ab6 gpu: Separate device suitability from device rank when enumerating Vulkan devices. 
This makes it a bit clearer what the "minimum" is vs. the "best", which should be two separate queries.
 2025-11-10 18:16:54 -05:00
Ethan Lee 6976b57988 gpu: Move device ranking to the bottom of IsDeviceSuitable. 
This prevents devices without presentation/graphics support from getting ranked.
 2025-11-10 18:16:54 -05:00
Ethan Lee 799c6aa629 gpu: Move device ranking to a standalone function. 
This allows us to treat Dozen as an "other" driver, rather than blacklisting it outright.

Frank Praznik f6a05121ec wayland: Handle dispatch errors when showing a window 
If a dispatch event when showing a window returns a failure code, handle the display disconnected condition and break out of the loop, otherwise, it will hang forever.

Frank Praznik 5d0236ad51 wayland: Don't leave un-acked configurations when throttling resize events 
Compositors that send multiple resize events per frame could result in the most recent configuration requests being left un-acked when the resize ends. Ack the most recent resized state on frame callbacks, so as to always ack the most recent configuration within a reasonable timeframe.

Sam Lantinga a96664674f Fixed windows events on 32-bit Windows
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled 
When running on 32-bit Windows, DefWindowProc resolves to a function in ntdll.dll, but after the window is created the actual window proc is a function in user32.dll. We solve this by using our own custom default window proc and looking for that instead.

Sam Lantinga 704ac98d3f Make sure the blit mapping is cleared when undoing RLE encoding 
This fixes a crash if a surface is RLE encoded, then locked and unlocked.

We also mark the surface as no longer needing to be locked after undoing RLE encoding

Sam Lantinga 089dc86bcf Lazily redo RLE encoding
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled 
Also stop lying about the RLE encoding state, which causes crashes if we do RLE blit operations while the surface is locked.
 2025-11-08 14:51:27 -08:00
Sam Lantinga cc2a272d6f Enable RLE more often in the software renderer 
We don't need to aggressively disable RLE acceleration anymore because the original pixels remain available for operations that aren't supported by the RLE blitter.
 2025-11-08 14:51:27 -08:00
Sam Lantinga ac0edbe9d2 Just assert that RLE encoding isn't active 
We undo RLE encoding in the calling code, so we shouldn't need to do anything here.
 2025-11-08 14:51:27 -08:00
Sam Lantinga 2b365983db Save the original pixels when RLE encoding is enabled 
Trying to reconstruct the original image when undoing RLE encoding was never completely accurate.

Chris Genova 6a01d6e7d3 D3D12 GPU: Prevent reading out of bounds when uploading textures.
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled 
When the upload needs realignment, a new buffer is created to do the
upload, and the source data is copied to the new buffer. This commit
fixes the issue where the memcopy can read off the end of the source
buffer since it is reading based on destination pitch instead of source
pitch.

Frank Praznik 950a9a72ab wayland: Use a pool to allocate icon image buffers 
Allocate the buffers from a pool to avoid a separate mmap for each image.
 2025-11-07 13:53:00 -05:00
Frank Praznik b3060956c3 wayland: Release the SHM pool after initial cursor buffer creation 
The backing memory will be automatically unmapped when the buffer objects are destroyed, so no need to keep the pool around.

Sam Lantinga 118dcf27ce Added D mode mappings for the 8BitDo 64 Bluetooth Controller 
The HID descriptor maps the C buttons as a right thumbstick, but this mapping matches the HIDAPI Nintendo 64 mapping.

The start button resets the controller in both USB and Bluetooth mode on macOS, but I've kept the mapping assuming this is a macOS bug that will be fixed.

Sam Lantinga 9ff737efbd Updated the Nintendo Switch N64 controller mapping 
This mapping matches the Linux kernel default mapping.

Correcting it when it is subsequently hidden and re-mapped will cause the position to be double offset by the size of the borders.
