mesa/texture: Also check for LA texture when querying intensity component size
Gallium may pick L16A16_FLOAT to represent GL_INTENSITY16F if no intensity format is provided by the driver. However, when calling glGetTexLevelParameteriv(..., GL_TEXTURE_INTENSITY_SIZE, ...) mesa will return a zero size because the actually used format has no intensity channel and as a fallback only the sizes of the red/green channels are checked. Also checking for LA sizes in the allocated texture resolves this problem. v2: Only check alpha channel size and return it (Marek) L and A size are always the same in this case. Fixes (on virgl): ext_framebuffer_multisample-fast-clear GL_ARB_texture_float * Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107832 Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
