Thanks for sharing the compiler work. Although I can't understand the new algorithm immediately after quick scan of the code and your comments, I'll get back and try to understand...

viewport transform will be applied to each vertex at the end of GP shader: V * viewport_scalar + viewport_translate viewport->translate[2] is the Z value.

You mean "no" or "now"?

One way I can think of is creating a gbm_bo and attach it to FBO's GL_DEPTH_ATTACHMENT.

Sorry, I don't know either. The zsbuf I just write it there for reminder, haven't actually use it. But from the lima-ng, I also can't find a dedicated depth buffer...

Could this possible: 1. for app not use the depth buffer explicitly (attached to FBO's depth slot), mali don't need a depth buffer at all 2. for explicit usage, one...

From the dump, mali blob driver will do clear even user does not call glClear when EGL_BUFFER_DESTOYED. But when EGL_BUFFER_PRESERVED, lima_pp_wb_reg[0] and lima_pp_wb_reg[1] will be set to different target address,...

I have no idea as it's not dumped out, but should be a buffer used for write. Maybe some aux/tmp/mirror buffer? In fact I don't know why there're three wb...

Progress update 1. fix the PP error irq and MMU fault due to not enough PLB number 2. fully mali450 support with DLBU and BCAST used for PP jobs Next...

What's your screen resolution when this kind of error happens? I remember you said you have a 2536x1440 monitor? I fix this error when 1920x1080 and the PLB number is...
