Hi Qiang,
I am using Lima on the ST-Ericsson U8500 SoC. It is one of the very earliest versions of MALI 400 MP. It mostly works on the mobile phones I have using PostmarkeOS and the Phosh UI (Wayland with MESA), but now I have an issue with one single specimen.
I have this bug in my dmesg and after this the graphics start to act weird:
[ 48.662336] lima a0300000.gpu: mmu page fault at 0x2020400 from bus id 0 of type read on ppmmu0 [ 48.662464] lima a0300000.gpu: fail to save task state from phoc pid 1581: error task list is full [ 48.662481] lima a0300000.gpu: pp task error 0 int_state=0 status=1 [ 48.662494] lima a0300000.gpu: mmu resume
In interrupts:
75: 5 0 GIC-0 147 Level gp 76: 0 0 GIC-0 146 Level gpmmu 77: 3 0 GIC-0 145 Level pp0 78: 1 0 GIC-0 144 Level ppmmu0
My UI definitely want to render some more stuff so it gets stuck here.
Any hints on how to troubleshoot this?
Yours, Linus Walleij
