From c0beaf6e6d5764531a4cb21d0d0a9a1fd09affee Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Thu, 10 Feb 2011 02:16:58 +0100 Subject: st/mesa: allow rendering to sRGB textures if EXT_fb_srgb is unsupported In this case, we always use the corresponding linear format in create_surface, therefore we should check for linear format support as well. --- src/mesa/state_tracker/st_cb_fbo.c | 29 ++++++++++++++++++++++++----- 1 file changed, 24 insertions(+), 5 deletions(-) diff --git a/src/mesa/state_tracker/st_cb_fbo.c b/src/mesa/state_tracker/st_cb_fbo.c index 398e32a345..0b0ad16eaa 100644 --- a/src/mesa/state_tracker/st_cb_fbo.c +++ b/src/mesa/state_tracker/st_cb_fbo.c @@ -448,11 +448,14 @@ st_finish_render_texture(struct gl_context *ctx, * Validate a renderbuffer attachment for a particular set of bindings. */ static GLboolean -st_validate_attachment(struct pipe_screen *screen, +st_validate_attachment(struct gl_context *ctx, + struct pipe_screen *screen, const struct gl_renderbuffer_attachment *att, unsigned bindings) { const struct st_texture_object *stObj = st_texture_object(att->Texture); + enum pipe_format format; + gl_format texFormat; /* Only validate texture attachments for now, since * st_renderbuffer_alloc_storage makes sure that @@ -464,7 +467,20 @@ st_validate_attachment(struct pipe_screen *screen, if (!stObj) return GL_FALSE; - return screen->is_format_supported(screen, stObj->pt->format, + format = stObj->pt->format; + texFormat = + stObj->base.Image[att->CubeMapFace][att->TextureLevel]->TexFormat; + + /* If the encoding is sRGB and sRGB rendering cannot be enabled, + * check for linear format support instead. + * Later when we create a surface, we change the format to a linear one. */ + if (!ctx->Const.sRGBCapable && + _mesa_get_format_color_encoding(texFormat) == GL_SRGB) { + const gl_format linearFormat = _mesa_get_srgb_format_linear(texFormat); + format = st_mesa_format_to_pipe_format(linearFormat); + } + + return screen->is_format_supported(screen, format, PIPE_TEXTURE_2D, stObj->pt->nr_samples, bindings, 0); } @@ -528,20 +544,23 @@ st_validate_framebuffer(struct gl_context *ctx, struct gl_framebuffer *fb) return; } - if (!st_validate_attachment(screen, + if (!st_validate_attachment(ctx, + screen, depth, PIPE_BIND_DEPTH_STENCIL)) { fb->_Status = GL_FRAMEBUFFER_UNSUPPORTED_EXT; return; } - if (!st_validate_attachment(screen, + if (!st_validate_attachment(ctx, + screen, stencil, PIPE_BIND_DEPTH_STENCIL)) { fb->_Status = GL_FRAMEBUFFER_UNSUPPORTED_EXT; return; } for (i = 0; i < ctx->Const.MaxColorAttachments; i++) { - if (!st_validate_attachment(screen, + if (!st_validate_attachment(ctx, + screen, &fb->Attachment[BUFFER_COLOR0 + i], PIPE_BIND_RENDER_TARGET)) { fb->_Status = GL_FRAMEBUFFER_UNSUPPORTED_EXT; -- cgit v1.2.3
