Subject: M112: Mark RGBX and BGRX formats as having 8 unused bits.
|
|
|
|
This makes sure that pixelBytes ends up being 4 and fixes potential
|
|
buffer size validation.
|
|
|
|
Fix EGL configs using pixelBytes to compute EGL_BUFFER_SIZE which
|
|
is not supposed to include unused bits. This is covered by
|
|
dEQP-EGL.functional.query_config.constraints.color_buffer_size
