Elias Naur	7f6e376424	gpu,gpu/internal: support variable strides in ReadPixels ... It saves a roundtrip to scratch memory when the CPU fallback renderer downloads rendered materials. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-27 12:59:01 +02:00
Elias Naur	7acc031ccf	gpu/internal/metal: merge buffer address and size calls ... Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-23 17:56:57 +02:00
Elias Naur	b47653b808	gpu/internal/metal: don't double-buffer staging memory ... One staging buffer is enough because BeginFrame waits for the completion of the staging operatoins from the previous frame. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-23 17:48:59 +02:00
Elias Naur	43a7030f6e	gpu/internal/metal: use optimal CPU cache mode for staging buffers ... Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-22 17:46:28 +02:00
Elias Naur	c9970cb8e3	gpu,gpu/internal,internal/gl: replace BlitFramebuffer with CopyTexture ... OpenGL ES 2.0 doesn't support glBlitFramebuffer, but does support glCopyTexSubImage2D. Fortunately, we don't need the extra features of glBlitFramebuffer anyway. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-21 11:16:28 +02:00
Elias Naur	3b2992c37e	gpu,app/internal/wm: add Metal port ... The OpenGL (ES) implementations on Apple platforms are deprecated and don't support GPU compute programs. This change adds support for the replacement, the Metal GPU API. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2021-08-21 08:31:46 +02:00
