Advanced users • Re: Moving Linux Kernel to 6.12

Hi,

Did some NUMA testing on my Raspberry PI 5 8GB with 6.12.1 and thought i should post this here since it seems more related to 6.12 than NUMA. I have switched between the kernels and benchmarked several times to get consistent results. I also tested without setting SDRAM_BANKLOW=1 in rpi-eeprom-config. The GPU performance has a negativ effect with some benchmarks with NUMA but it is a lot worse in 6.12.1. Included Geekbench 6 which give similar results on all kernels.

Benchmarks:

KERNEL 6.6.62+rpt-rpi-2712

glmark2-wayland:
2096 Points (without SDRAM_BANKLOW=1)
1808 Points (with SDRAM_BANKLOW=1)

Fishtank (1000 Fish):
38 FPS (without SDRAM_BANKLOW=1)
36 FPS (with SDRAM_BANKLOW=1)

Geekbench 6:
Single=921, Multi:1806 (without SDRAM_BANKLOW=1)
Single=1018, Multi: 2269 (with SDRAM_BANKLOW=1)


KERNEL 6.6.63

glmark2-wayland:
2085 Points (without SDRAM_BANKLOW=1)
1806 Points (with SDRAM_BANKLOW=1)

Fishtank (1000 Fish):
38 FPS (without SDRAM_BANKLOW=1)
36 FPS (with SDRAM_BANKLOW=1)

Geekbench 6:
Single=920, Multi:1775 (without SDRAM_BANKLOW=1)
Single=1020, Multi: 2258 (with SDRAM_BANKLOW=1)


KERNEL 6.12.1

glmark2-wayland:
1315 Points (without SDRAM_BANKLOW=1)
1155 Points (with SDRAM_BANKLOW=1)

Fishtank (1000 Fish):
28 FPS (without SDRAM_BANKLOW=1)
26 FPS (with SDRAM_BANKLOW=1)

Geekbench 6:
Single=923, Multi:1767 (without SDRAM_BANKLOW=1)
Single=1020, Multi: 2259 (with SDRAM_BANKLOW=1)
