03:08 <macc24> alyssa: RA?

03:11 <HdkR> Register allocator

03:11 <macc24> ohh

03:21 <icecream95> Okay, so this time I really have fixed all the bugs in the UBO pushing/sysvals rewrite, now I just need to fix up the mess of a commit log...

08:38 <daniels> anarsoul: right, you may require composition passes, but the rule there is that if you read from a protected surface, all of your writes have to in turn be to protected surfaces

16:00 <alyssa> bbrezillon: Do you intend on using blend shaders in panvk?

16:01 <alyssa> I'm not sure I see value in doing so, since the primary function of blend shaders is avoiding fragment shader keys for framebuffer format and blend mode, but in vk you have all that at pipeline create time.

16:15 <bbrezillon> alyssa: hm, I use it, but maybe that's a mistake

16:18 <bbrezillon> alyssa: there's still the constants that can be changed dynamically

16:22 <bbrezillon> which might force the frag shader compilation when vkCmdDraw() is called if we don't use blend shaders. We can of course cache a few variants to avoid recompiling the frag shader every time the blend constants change, but I'm not sure it's any better than using blend shaders

16:24 <bbrezillon> uh, wait, you're right, if we pass the blend constants through a uniform and do the blend lowering directly in the fragment shader we don't need blend shaders at all

21:03 <icecream95> Yay, more things to RE! "CSF replaces Mali job manager. Consists of CPU, hardware and firmware"

21:04 <daniels> yeah, job submission gets fun

21:05 <daniels> not much to RE tho, r30p0 kernel sources already have it implemented

21:07 <alyssa> bbrezillon: Yeah, just use uniform for blend constants like { vc4, v3d, asahi }
