Mar 04, 2024
In my pcie switcher system, there are one rc and two ep. Every ep’s BAR0_SIZE is SZ_512M. When i set BAR0_SIZE to SZ_2G, and on rc, lspci -v：
0005:12:00.0 RAM memory: NVIDIA Corporation Device 1ada
Flags: fast devsel, IRQ 39
Memory at 1c00000000 (64-bit, prefetchable) [disabled] [size=128K]
Memory at (64-bit, non-prefetchable) [disabled]
I download jetson4.6 source code.
how to support BAR0_SIZE to SZ_2G or SZ_4G?
