Hi Phillipe,
I needed to test some Xen things on a model I could debug so I took
the liberty of re-basing you patches from a 2 years ago. Most of the
changes involve dropping patches since merged and dealing with the
resultant merging fallout. The fix I posted on Friday for the
calculation of the ram base for kernel loading is included. Other
tweaks involve moving the location of peri_base to what is indicated
by the DTBs (I'm still not sure where the Linux addresses come from,
does it re-map the physical address space somewhere?).
My testing ended at getting Xen to boot up and at least echo some
stuff to the console:
./qemu-system-aarch64 -machine raspi4b -serial mon:stdio -kernel
~/lsrc/xen/xen-only.cross.arm64/xen/xen -append "dom0_mem=1G,max:1G loglvl=all
guest_loglvl=all console=d
tuart dtuart=serial0 sync_console" -display none -dtb ./bcm2711-rpi-4-b.dtb
- UART enabled -
- Boot CPU booting -
- Current EL 00000008 -
- Initialize CPU -
- Turning on paging -
- Zero BSS -
- Ready -

My next steps involve debugging Xen so I thought I'd post where I am
for the next person that wants to properly wire up the Pi4.
