Hello Mr. Kiszka,
Sure I can write a patch for this. Meanwhile, did you have a chance to read the
rest of the e-mail that I sent? Currently Jailhouse fails when I enable it, but
there are no error messages in the serial output. I am attaching the files
again.
Sorry, missed that.
I created a sysconfig file with "jailhouse config create sysconfig.c" and when I try to run Jailhouse I get
the following error message: "JAILHOUSE_ENABLE: Cannot allocate memory". However, I do not see an error
message in the serial output. My GRUB parameters inside /etc/default/grub has the following two set:
"amd_iommu=off memmap=0x5200000\\\$0x3a000000". I am not sure if amd_iommu should be on or off, it was set as
"on" by default.
Try assigning more memory to the hypervisor first (.hypervisor_memory.size).
Start with 64M, to be safe. But, when you increase that size manually, make sure
to not overlap with existing assignments, i.e. move them as well.
Ralf (in CC) recently enabled Jailhouse on an AMD box. Maybe this setup is
similar, and he can share some tricks.

Thanks and best regards,

Hello Mr. Kiszka,
I have confirmed that we are on commit f743631213a1 without modifications. I went into the source code in the file
"/usr/local/libexec/jailhouse/jailhouse-hardware-check", inside the "elif cpu_vendor == 'AuthenticAMD':"
branch, in the last loop I see that there are two variables named "n", one in the outer loop and one in the inner loop.
Changing the name of the variable "n" in the inner loop fixes the error in the "jailhouse hardware check"
command. So the following lines:
for n in range(num_filter_regs):
smi_freg = mmio.read64(0x60 + (n << 3))
becomes
for nn in range(num_filter_regs):
smi_freg = mmio.read64(0x60 + (nn << 3))
After this modification, "jailhouse hardware check" command gives the following
output:
Good catch! Would you like to write a patch so that this gets fixed for
everyone?
Thanks in advance,
Jan
