With that change you could change all the calls below to something like if (_mesa_tex_storage_invalid_dim(width, height, depth)) { _mesa_error(ctx, GL_INVALID_VALUE, "glTexStorage2DMultisample()" return; }Would it be OK if we do possible unification for checking samples parameter after these patches? My goal here is to do check for glTexStorage*Multisample only. I don't feel comfortable changing checks for other functions at the same time, that should deserve it's own commit so it's easier to bisect later.There is no reason to split the change into two patches. The correct change is to update _mesa_texture_image_multisample (which I will rename texture_image_multisample once your patch lands) to do the samples check. The only other user is image*Multisample and the spec clearly states that this is also an error when 0. That spec says it undefined what happens when this is negative but we already throw an error via _mesa_check_sample_count().OK, how about land your patch first so that we can test for regressions. If nothing regresses after your changes then I can safely land mine.The changes are pushed to master :)
OK nice, I've updated my patch to not check samples (only dimensions). Do you want me to send it separately or are you ok giving r-b with these changes?
You don't have to touch _mesa_check_sample_count() that change should be in another patch which I already sent [1] feel free not to review it :) Doing it the way your suggesting is code churn for no gain, it just means your code needs to be deleted and replaced with the change I'm suggesting later anyway, so why not just fix it right the first time.Yes, maybe I'm too pessimistic that nothing would break. It's just that typically something does and I've been really hard trying to not break ES 3.0 conformance (which includes ES 2.0 tests too) while making ES 3.1 changes. We are very close to being ES 3.0 conformant (just one test failing ATM).Nice work. I can see where your coming from but if we are going to break things now is the time to do it while people like yourself are keeping a close eye on things :)Also feel free to keep your valid_texstorage_ms_parameters() function I was just suggesting an alternative to having another function call.
