Hi
I have formally tested the patch with 5.7.10 - and it doesn't resolve the issue - sadly :(
From my testing, the reads on VIVS_HI_CHIP_PRODUCT_ID VIVS_HI_CHIP_ECO_ID need to be conditional - while VIVS_HI_CHIP_CUSTOMER_ID seems to be okay.
Uhh.. okay.. just send a V2 - thanks for testing :)
There is also something else going on with the GC600 - 5.4 worked fine, 5.8 doesn't - my 2D Xorg driver gets stuck waiting on a BO after just a couple of minutes. Looking in debugfs, there's a whole load of BOs that are listed as "active", yet the GPU is idle:

My guess is there's something up with the way a job completes that's causing the BOs not to be marked inactive. I haven't yet been able to debug any further.
