Decode PQ/BT.2020 desktop pixels into an FP16 linear scRGB target before
compositing the color cursor, ImGui, damage overlay, and letterboxing.
Encode the damaged result to PQ once at the surface boundary. Keep logical
AND/XOR cursor masks in the encoded domain.
This preserves premultiplied cursor edges, prevents encoded-domain
blending, uses the Wayland output reference white for local overlays, and
keeps guest cursor white and display calibration independent from frame
SDR white. It also corrects HDR-to-SDR absolute luminance scaling, gamut
matrices, black handling, and buffer-age repair for the extra pass.
Suppress overlays when their conversion framebuffer is unavailable rather
than allowing unconverted sRGB draws into an HDR target.
Use named transfer constants for cursor shader state. Convert clipped
surface rectangles explicitly before using the frame-damage merge helper,
which avoids mixing its unsigned type with the EGL surface rectangle type.
Only advertise native PQ when the FP16 composition target is available.
SDR and native scRGB retain their direct single-pass paths.
Request true floating-point EGL configs for scRGB and expose the native
encodings supported by the selected surface. Fall back to software HDR
mapping when the surface cannot represent the incoming wire format.
Resample PQ in linear light, keep SDR-only effects out of native PQ
chains, and consume the cursor-specific white level without changing
binary monochrome cursor mask operations.
Keep software HDR mapping enabled until the display server activates the
requested image description. Re-evaluate the state while rendering so
asynchronous readiness or failure updates the desktop, cursor, and overlay
together with a full redraw.
Honor the IddCx 3x4 XYZ matrix and post-transfer LUT in the IDD
conversion pipeline. Carry transform changes to the client so EGL applies
the same calibration to hardware cursors, and invalidate the full frame
whenever calibration changes.
Apply the same sampling margin to swap damage as buffer-age repair and
clip reported rectangles to the EGL surface. This ensures compositors
update every pixel affected by scaling or filtering.
Render ImGui to an intermediate SDR framebuffer and map it into the
native PQ or scRGB output using the Wayland surface reference white.
Preserve premultiplied alpha during conversion and limit composition to
damaged overlay regions.
Build the active filter chain only when its configuration changes,
including filter settings or order, input format, dimensions, output
size, and DMA mode.
Unchanged frames now execute only the cached active filters, avoiding
repeated setup, preparation, and output-resolution queries.
Reconfiguration forces a full-frame pass to prevent stale intermediate
framebuffer contents.
Also refresh CAS and FSR uniforms when loading presets and move
downscale pass selection out of the per-frame path.
Track context-local GL bindings to avoid redundant program, framebuffer,
buffer, texture, sampler, viewport, blend, and scissor state changes.
Invalidate the cache across context switches, ImGui rendering, and
shared object changes. Preserve CPU-backed texture upload correctness by
explicitly clearing pixel unpack buffer bindings where required.
This reduces hot-path driver overhead without adding waits or GPU
synchronization.
Track PBO fences per upload slot and wait only when a slot is reused,
allowing rendering to proceed without a CPU stall. Use GPU-side waits
for cross-context DMABUF synchronization.
Also propagate KVMFR write-completion failures so incomplete
shared-memory frames are never submitted, while retaining incremental
damage-copy waits to avoid added latency.
Replace the per-frame uniform list with stable, name-cached handles that
retain their values across shader recompilation. Track dirty uniforms so
only changed values are uploaded, reducing redundant GL calls and buffer
management.
Add a reusable effect-pass pipeline with per-pass shaders, samplers,
formats, resolutions, and intermediate render targets. This makes
external effects easier to integrate and supports arbitrary multipass
chains.
Migrate the desktop, cursor, damage, 24-bit, downscale, CAS, and FSR
rendering paths to the new APIs. Also ensure framebuffer objects are
released correctly.
* Removes the vector in favour of a two element array
* Removes iteration on the vector
* Create and track a per-image fence
* bind the EGLImage to the texture at creation, avoiding re-binding
* sync on GL_SYNC_FLUSH_COMMANDS_BIT and remove glFlush
GL_TEXTURE_EXTERNAL_OES is not a valid target for glTexImage2D and there
is no need to "create" the textures as this is done during import by
eglCreateImage
This patch performs several changes.
* Alters the fourcc codes to types that ignore the alpha channel where
possible to allow the gpu to internally use 24-bit formats.
* Attempts to use DRM_FORMAT_RGB888 first as some GPUs may support this
* If DMABUF is not in use the data is now imported directly as RGB24
without the post-processing shader
