• drm/etnaviv: Update idle bits. Update the state HI and common header from rnndb commit commit 19280a95a (rnndb: Update idle bits)
• drm/etnaviv: Consider all kwnown idle bits in debugfs. We were missing out on some bits the vendor kernel driver knows about.
• drm/etnaviv: Ignore MC when checking runtime suspend idleness. Without that runtime suspend is often blocked like [ 280.159111] etnaviv-gpu 38000000.gpu: genpd_runtime_suspend() ... Idle mask is 0x7fffbffe ... [ 418.893082] etnaviv-gpu 38000000.gpu: genpd_runtime_suspend() Idle mask flips to 0x7ffffffe, suspend happens: [ 418.926765] etnaviv-gpu 38000000.gpu: suspend latency exceeded, 33667107 ns [ 418.926862] PM: gpu: Power-off latency exceeded, new value 80280 ns This can sometimes be reproduced by hitting CTRL-C in kmscube but it also happens during normal operation. Tested on GC7000.
• drm/etnaviv: Warn when GPU doesn't idle fast enough. If the GPU isn't idle after signalling pm_runtime_mark_last_busy() plus waiting for the autosuspend delay there's likely something wrong with the way we check idleness so warn about that.
