Folks,
I am trying to boot Xen using efibootmgr on a Dell E6410 laptop with 4GB
RAM, running an Intel I5 dual core with VT and all the virtualization
options enabled.
It crashes almost immediately. I am working on getting the serial
console up so that I can get a more detailed stack.
A screenshot of the console is attached.
The xen.cfg file is:
[global]
default=xen
[xen]
options=console=vga,com1 com1=115200,8n1 dom0_max_vcpus=2 vga="qxl"
kernel=vmlinuz-3.8.13-48.el7uek.Other_EFI_v1.x86_64
root=UUID=917bfc7f-8d9c-4acf-a98a-a9f558daccf2 ro console=hvc0
enforcing=0 biosdevname=0 earlyprintk=xen nomodeset
ramdisk=initramfs-3.8.13-48.el7uek.Other_EFI_v1.x86_64.img
The codepath is "(gdb) x/20i get_cmos_time

The first is that we call into the efi runtime via efi_rs->GetTime, and a pagefault happens for the instruction at 0x00000000db25a33d for the virtual address 0x00000000fed1f410 The memory map looks quite weird, but the faulting address is covered in this range. (XEN) 00000fed1c000-00000fed1ffff type=11 attr=8000000000000000 So I would expect it to be mapped into the EFI pagetables. The EFI code is a mix of #ifdefs. Can you confirm whether you are compiling with USE_SET_VIRTUAL_ADDRESS_MAP or not? The second is that once the pagefault has happened, we trap back into Xen and attempt to do a pagetable walk, falling over an assertion in map_domain_page(). For EFI calls, we run on the efi pagetables, not the idle pagetables, so I am not surprised that the assertion has failed. I suspect that the pagefault hander for hypervisor faults needs to become wise to the fact that we may receive a fault when calling into the firmware. As all the efi pagetables are xenheap pages, there is nothing conceptually wrong with using map_domain_page() to do the walk. ~Andrew ^ permalink raw reply [flat|nested] 14+ messages in thread

Then you must have missed (XEN) Unknown cachability for MFNs 0xfed1c-0xfed1f which means no mapping got established (as we don't know what cachability attributes to give to it). This is a firmware bug. > The EFI code is a mix of #ifdefs. Can you confirm whether you are > compiling with USE_SET_VIRTUAL_ADDRESS_MAP or not?

But yes, if we really want to, extending the condition to also consider efi_l4_pgtable would seem the right thing to do. Jan ^ permalink raw reply [flat|nested] 14+ messages in thread

I think being able to do a pagetable walk from an EFI fault would be useful, even if only to aid debugging. In this case, a non-debug build would successfully perform the walk. I have had a quick go, but it is rather hard to get the efi_l4_pgtable symbol available to use in domain_page.c without some gross extern'ing. It would be a nice fix if anyone has sufficient tuits. ~Andrew ^ permalink raw reply [flat|nested] 14+ messages in thread

As a result, you can't reference efi_l4_pgtable in non-efi code without breaking the non-efi build, and there is no CONFIG_EFI or equivalent as domain_page.c isn't recompiled. ~Andrew ^ permalink raw reply [flat|nested] 14+ messages in thread

Marcos, it would be nice if you could try the 1st patch on that series individually and, independently, the 1st plus 2nd (or, if you like, all three, the last one being cosmetic) of the series at http://lists.xenproject.org/archives/html/xen-devel/2014-10/msg02856.html Thanks, Jan ^ permalink raw reply [flat|nested] 14+ messages in thread

Thanks, this confirms the secondary issue is fixed for you too. Now please see whether with both (or all three) patches applies (and with "no-efi-rs" on the Xen command line) the crash also goes away. Jan ^ permalink raw reply [flat|nested] 14+ messages in thread

It only boots with "no-efi-rs". With 1, 2 or 3 of the patches applied, it crashed. I ran with "no-efi-rs" only with all 3 patches applied. I could run the other two combinations if necessary. The crash with all 3 patches is attached. Another thing that happened, when it boots, the console for the OS is not available. Not exactly sure why, but I tried various possible solutions I found on Google, but none worked. > Jan > -- Regards, Marcos Eduardo Matsunaga Oracle USA Linux Engineering “The statements and opinions expressed here are my own and do not necessarily represent those of Oracle Corporation.” [-- Attachment #2: minicom.no-efi-rs --] [-- Type: text/plain, Size: 33505 bytes --] Xen 4.5.0-rc-0.rc1.0_rc1.30020140839.fc20 (XEN) Xen version 4.5.0-rc (mockbuild@[unknown]) (gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-7)) debug=y Mon Oct 27 11:49:02 EDT 2014 (XEN) Latest ChangeSet: (XEN) Console output is synchronous.

Looking at the Linux code > (efi_enter_virtual_mode_generic, it will pick 'efi_ioremap' which > calls 'ioremap' (which calls ioremap_nocache) I intentionally didn't follow Linux'es model here. There are dedicated flags for all caching modes (including UC), so if the UC flag is off we shouldn't be using that caching mode. You may be able to convince me to make this command line triggerable behavior, but I really think firmware folks should get their act together rather than make us invent bogus workarounds.
