00:24 <alyssa> i509vcb: possibly you're mixing up util_format_is_compressed style compressed (ASTC, ETC, BCn, PVRTC) with Apple's framebuffer compression scheme (COMPRESSED_TWIDLDED)

00:24 <alyssa> ?

00:24 <alyssa> the former is indeed not renderable on virtually any hardware

00:25 <i509vcb> Yeah I've heard of compressed texture formats typically being used to reduce ram usage in games. I'm talking specifically about the twiddled tiling

00:29 <i509vcb> (off topic, I don't exactly know if the dcp can scan out the special apple drm modifiers)

00:31 <i509vcb> I've pretty much been working on what's needed so that the wsi can allocate images with a non-linear tiling

00:35 <alyssa> nice

01:54 <i509vcb> alyssa: was the plan to implement vkCmdBlitImage with vk meta like image and buffer copies?

02:03 <i509vcb> (I'm guessing yes because I saw the blit stuff already is there)

02:40 <i509vcb> hmm that wants load_layer_id, random crapshoot at the cmdbuf that appears to be something related to AGX_PBE?

02:44 <i509vcb> On that topic what is PBE?

09:08 <alyssa> yes for blit

09:08 <alyssa> Pixel BackEnd, the hardware used to write to colour attachments & images

09:08 <alyssa> and also the name of the descriptor passed to PBE instructions
