devinfo also need hacks for map:
pci130
t5nex0
Interrupt request lines:
0x120
0x121
0x122
0x123
0x124
0x125
0x126
0x127
0x128
0x129
0x12a
0x12b
0x12c
0x12d
0x12e
0x12f
0x130
0x131
0x132
0x133
0x134
0x135
pcib11 memory window:
0xf9000000-0xf9ffffff
0xfa300000-0xfa37ffff
0xfac04000-0xfac05fff
cxl0
cxl1
devinfo don't show detailes about IRQ handelrs:
# vmstat -i
irq289: t5nex0:evt 17 0
irq290: t5nex0:0.0 235629333426 39932
irq291: t5nex0:0.1 235835938497 39967
irq292: t5nex0:0.2 236414122597 40065
irq293: t5nex0:0.3 234357043791 39716
irq294: t5nex0:0.4 228105465543 38657
irq295: t5nex0:0.5 229347649630 38867
irq296: t5nex0:0.6 230949738393 39139
irq297: t5nex0:0.7 230484724411 39060
irq298: t5nex0:0,0 78781 0
irq299: t5nex0:0,1 90592 0
and not devinfo not vmstat don't provide information about relations
between CPU sockets and PCIe slots (cxl0 connect to PCIe handled
second socket).
Also, on other box:
# acpidump -dt
/*

And talk 'userland' I talk about API, from program, library call.
Utility for shell need too.
