Author: Wladimir J. van der Laan <[email protected]> Date: Wed Dec 7 12:59:54 2016 +0000 etnaviv: Cannot render to rb-swapped formats Exposing rb swapped (or other swizzled) formats for rendering would involve swizzing in the pixel shader. This is not the case at the moment, so reject requests for creating such surfaces. (GPUs that need an extra resolve step anyway due to multiple pixel pipes, such as gc2000, might also do this swap in the resolve operation. But this would be tricky to keep track of) CC: <[email protected]> Signed-off-by: Wladimir J. van der Laan <[email protected]> Acked-by: Christian Gmeiner <[email protected]> --- src/gallium/drivers/etnaviv/etnaviv_screen.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/etnaviv/etnaviv_screen.c b/src/gallium/drivers/etnaviv/etnaviv_screen.c index c045f7e..7c1609f 100644 --- a/src/gallium/drivers/etnaviv/etnaviv_screen.c +++ b/src/gallium/drivers/etnaviv/etnaviv_screen.c @@ -471,8 +471,11 @@ etna_screen_is_format_supported(struct pipe_screen *pscreen, return FALSE; if (usage & PIPE_BIND_RENDER_TARGET) { - /* if render target, must be RS-supported format */ - if (translate_rs_format(format) != ETNA_NO_MATCH) { + /* If render target, must be RS-supported format that is not rb swapped. + * Exposing rb swapped (or other swizzled) formats for rendering would + * involve swizzing in the pixel shader. + */ + if (translate_rs_format(format) != ETNA_NO_MATCH && !translate_rs_format_rb_swap(format)) { /* Validate MSAA; number of samples must be allowed, and render target * must have MSAA'able format. */ if (sample_count > 1) { _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
