Hi Alex,
dmesg | grep "no compatible bridge window"
pci 0000:00:01.0: can't claim BAR 1 [mem 0xd000000000-0xd00fffffff 64bit
pref]: no compatible bridge window
...> From what I can read from all the info above,
somehow the requested memory space for BAR1 for that device is
0xd000000000-0xd00fffffff which is out of addressable space on the system.
Yep, that's the issue, and it's a bhyve bug - there is no check to see
if the 64-bit window is within the addressable range of the processor.
A quick fix is to change the constant for that range in pci_emul.c
#define PCI_EMUL_MEMBASE64 0xD000000000UL
#define PCI_EMUL_MEMLIMIT64 0xFD00000000UL
.. to a value that is within the address bits of the CPU, but also
above guest DRAM.
later,
Peter.
