I am currently trying to get Xen to boot on my Lenovo T430 laptop with
BIOS 2.68 and using master results in no output to the screen and the
machine being completely hung (must pull the power cable). I've gone
ahead and bisected it and the resultant commit is:

There is the SMBIOS table (that is the DMI) that is available during
before we need thse sort of overrides.
It could be implemented but I keep on going back to the valid
point that Jan raised: This is a firmware bug!!
Thought the other solution is to do what Linux does (SetVirtualAddressMap)
which would bypass the firmware bug - by executing these calls
after ExitBootServices has been called - and in virtual address mode
instead of the 1:1. This is just side-stepping the bug.
However the implementation that uses SetVirtualAddressMap
crashes right away - so it would need some work, while the
quirks are not the case.
I will let Jan and Andrew figure out what they want and can spin
some patches later on.

Is DMI available this early? That's the sort of thing we quirk on today, I
think (maybe an x86 person could confirm).

I am very much in favour of this. Based on XenServer testing, far more
systems are buggy than working, and turning on every workaround by
default is unlikely to end well.
At the end of the day, user of Xen want it to JustWork.

Would it be acceptable to create a quirks table and then we can add
different systems to the quirk?
e.g.
struct efi_quirks {
/* something identifying to the system */
uint32_t quirks;
} efi_quirks_table = {
{ /* Lenovo T420 / T430 v2.64 through v2.68 */, EFI_QUIRK_MAPBS |
EFI_QUIRK_NOEXITBS },
{ 0, 0 }
};
#define EFI_QUIRK_MAPBS 0x1
#define EFI_QURIK_NOEXITBS 0x2
I'm not sure what I can use to identify the system early on. I see the
EFI FW vendor and EFI FW revision. I'm not sure if that would be
enough. In the case of using that it would likely have to be a range
of revisions.
Thoughts?

OK, there is one more thing which I sadly have to use on my Lenovo
T420. See the inline patch and attached patch.
I end up doing xen.efi -basevideo -mapbs -noexitboot

Subject: [PATCH 2/2] EFI/early: Implement GetNextVariableName and /query and
/noexitboot parameters
In the early EFI boot we will enumerate up to five EFI variables
to make sure it works.
The /query will just enumerate them and then quit. Helps in
troubleshooting and redirecting the output to a file (xen.efi /query > q).
The /noexitboot will inhibit Xen from calling ExitBootServices.
This allows on Lenovo ThinkPad x230, T420 to use GetNextVariableName
in 1-1 mapping mode.

We added a bunch of overrides that may help.
The address looks to be for:
(XEN) 00000cea97000-00000ceaacfff type=4 attr=000000000000000f
Which is of EfiBootServicesData
Try on the Xen.efi command line to use /mapbs
You may have to install first EFI Shell Manager and then from there
execute the xen.efi /mapbs

So now I've got a build of staging
8398ec706ff60e17a5044470fa2e90a1b081f37a with debug=y and
frame_pointer=n so that we can get a good call trace. As Andrew
pointed out to me on IRC right now stack tracing is broken with EFI
boots due to a mix of using frame pointers (in Xen) and no frame
pointer (EFI). Here's the latest output:

dom0 has the following as the last line in dmesg:
EFI Variables Facility v0.08 2004-May-17
If I boot with "efi=no-rs" then the system will come up. I have to
boot the system from the EFI shell because booting from grub /
multiboot (the way Ubuntu is doing things by default) results in the
system unable to find the RSDP from ACPI. I assume that's because grub
is exiting boot services and the multiboot spec can not pass the
address of RSDP.
I have a similar failure with Xen 4.5.1. I'll include the last little
bit here for completeness:

This commit broke booting on just about every server.
New master has the fix it in, although there is one further fix ahead of
that. Try using bc299d01b925d934219b6e8c29fadcd1f1a9210b which is two
ahead of current master.

I am currently trying to get Xen to boot on my Lenovo T430 laptop with
BIOS 2.68 and using master results in no output to the screen and the
machine being completely hung (must pull the power cable). I've gone
ahead and bisected it and the resultant commit is:
commit 4824bdfdabebd4042277461cb3cbefa61c624804
Author: Chao Peng <chao.p.peng@linux.intel.com>
Date: Tue Jul 7 15:42:49 2015 +0200
x86: add socket_cpumask
Maintain socket_cpumask which contains all the HT and core siblings
in the same socket.

Since I'm not getting any output I'm at a loss how to debug this problem
further. I do have Intel AMT setup with Serial Over LAN working so if its
at all possible to get more info over serial I will do that. I am already
booting
Xen with console=vga,com1 com1=115200,amt loglvl=all so not sure what
else to add.
Thanks.
