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
Compiled in resources often will not contain a null terminator, as such
we must not use functions that rely on it. This implements a memsearch
function that performs like strstr on a buffer instead of a null
terminated string.
