https://bugs.freedesktop.org/show_bug.cgi?id=83500 --- Comment #8 from Christian K?nig --- Oh, yeah you're right got that wrong as well. But what I hoped to have checked as well is that it sounded like this copy command worked correctly in 90% of all cases and only in a minority just locked up.

https://bugs.freedesktop.org/show_bug.cgi?id=83500 --- Comment #7 from Michel D?nzer --- Yeah, sorry, I misread DW 3 as having array_mode == 0 when it's actually 2. -- You are receiving this mail because: You are the assignee for the bug. -- next part -- An HTML

https://bugs.freedesktop.org/show_bug.cgi?id=83500 --- Comment #6 from Grigori Goronzy --- The tiling parameters don't look bogus and they certainly aren't zero. In the dumped IB there's mt = 1, num_banks = 3, tile_split = 3 in DW 7. Looking at DW 3, there is array_mode = 2, bankw = 0, bankh =

[Bug 83500] si_dma_copy_tile causes GPU hangs

https://bugs.freedesktop.org/show_bug.cgi?id=83500 --- Comment #3 from Michel D?nzer --- Maybe we need to determine the other tiling parameters differently for 1D tiling? IIRC Marek fixed things like that before. Anyway, in the command stream dump you provided before, it looked like the tiling
