Hi,
After v4.14, I've been unable to boot my AMD compilation box with the
v4.15-rc mainline Linux. It just ends up in a silent reboot loop.
I bisected this to:
commit fa564ad9636651fd11ec2c79c48dee844066f73a
Author: Christian K?nig <[email protected]>
Date: Tue Oct 24 14:40:29 2017 -0500
x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f)
System details:
[ 0.000000] DMI: MSI MS-7699/760GA-P43(FX) (MS-7699) , BIOS V1.3 10/14/2014
[...]
[ 0.070000] smpboot: CPU0: AMD FX(tm)-6350 Six-Core Processor (family: 0x15, model: 0x2, stepping: 0x0)
If you need more info, please tell what you need.
With the current mainline (rc6+), I have done the following reverts to
get a bootable system:
Revert "x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f,
60-7f)"
This reverts commit fa564ad9636651fd11ec2c79c48dee844066f73a.
Revert "x86/PCI: Fix infinite loop in search for 64bit BAR placement"
This reverts commit 470195f82e4ea550b7c37736a12bf3fa565295ea.
Revert "x86/PCI: Only enable a 64bit BAR on single-socket AMD Family 15h"
This reverts commit a19e2696135efb471981c1ae1ec3cb2b70c41a2e.

Hmm. That was reported to break boot earlier already.
The breakage was supposedly fixed by three patches from Christian:
a19e2696135e: "x86/PCI: Only enable a 64bit BAR on single-socket AMD
Family 15h"
470195f82e4e: "x86/PCI: Fix infinite loop in search for 64bit BAR placement"
and a third one that was apparently never applied.
I'm not sure why that third patch was never applied, I'm including it here.
Does the system work for you if you apply that patch (instead of
reverting all of them)?
I wonder why that patch wasn't applied, but if it doesn't fix things,
I think we do need to revert it all.

Yes, I think it now works.
When booting with kexec from v4.14:
89876f275e8d562912d9c238cd888b52065cf25c alone ==> boot fails.
89876f275e8d562912d9c238cd888b52065cf25c and the patch ==> boot OK.
However, I noticed I cannot do multiple kexecs in a row - it works only
once, and the second one just silently fails/reboots the CPU regardless
what the kernel is. But this behaviour is already the same with v4.14. :-/

I also re-tested with normal reboot/reset and BIOS boot (just to eliminate
any kexec side-effects), and the results are the same. The patch
"x86/PCI: limit the size of the 64bit BAR to 256GB" is fixing the boot
on my system.

Ah, crap. We left this one out because it was just a hacky shoot into
the dark to potentially avoid problems.
Please provide me with a full dmesg of the system and the content of
/proc/iomem.
The most likely root cause is that your BIOS is buggy and reporting some
nonsense to the OS.
We either need to indeed limit the new PCI root window to 256GB or find
a better way to detect problematic BIOS versions.
Thanks in advance,
Christian.

I didn't apply the third patch ("x86/PCI: limit the size of the 64bit
BAR to 256GB") because (a) we thought it was optional ("just a
precaution against eventual problems"), (b) we didn't have a good
explanation of why 256GB was the correct number, and (c) it seemed to
be a workaround for a Xen issue that we hoped to fix in a better way.
It does apparently make Aaro's system work, but I still hesitate to
apply it because it's magical -- avoiding the address space from
0x1_00000000 to 0xbd_00000000 makes things work, but we don't know
why. I assume there's some unreported device in that area, but I
don't think we have any real assurance that the
0xbd_00000000-0xfd_00000000 area we now use is any safer.
I would feel better about this if we made it opt-in via a kernel
parameter and/or some kind of whitelist. I still don't really *like*
it, since ACPI does provide a mechanism (_PRS/_SRS) for doing this
safely, and we could just say "if you want to use big BARs, the BIOS
should enable big windows or at least make them available via ACPI
resources." The only problem is that BIOSes don't do that and we
don't yet have Linux support for _PRS/_SRS for host bridges.
I'll prepare a revert as a back-up plan in case we don't come up with
a better solution.

Well, I knew why it's not working. The BIOS is not telling us the truth
about how much memory is installed.
A device above 4GB would actually be handled correctly by the code (see
the check when we walk over all the existing IO regions).
I tested a bit with Aaro and came up with the attached patch, it adds a
16GB guard between the end of memory and the new window for the PCIe
root hub. But I agree with you that this is just a hack and not a real
solution.

Well that is the point I disagree on. When the memory map we get from
the BIOS is not correct it makes no difference if we enable the window
with the BIOS or by direct programming the hardware.
I will work with Aaron some more to come up with a solution which reads
the memory map directly from the hardware as well and checks if that is
valid before doing anything else.

Either that or only enable it when pci=add-root-window is given on the
kernel commandline.
Just let me know what you prefer and I will hack a patch for this
together today.

I don't agree with this approach. One goal of UEFI/ACPI is to remove
the need for the OS to directly peek at the hardware for things like
this.
In Aaro's case, the BIOS apparently does not describe all of system
memory in E820. ACPI r5.0, sec 15.1 describes E820 and it does say
that the the E820 interface "provides a memory map for all of the
installed RAM, and of physical memory ranges reserved by the BIOS,"
so one could argue that Aaro's BIOS is defective because it omits
something.
But I think the intent of the spec is that all non-discoverable
resources available to the OS will be described via E820, UEFI
GetMemoryMap(), ACPI tables, etc. So I think a BIOS engineer would be
on pretty safe ground to say "Mr. OS, we didn't tell you about X, so
you should not use X."
And, again with a BIOS engineer's hat on, I would argue that the BIOS
is entitled to use unreported things for its own purposes and rely on
the assumption that the OS will not use them.
So I'm not convinced this is necessarily a BIOS bug. If we peek at
the hardware directly for things the spec can express, I think we're
making the OS less portable and opening the door to conflicts with the
BIOS.

I don't like to add new parameters because I think it's an
unreasonable burden on users and it makes it hard for distros, but I
understand the desire to use this functionality. What would you think
of adding a "pci=big_root_window" parameter that logs an info message
and taints the kernel with TAINT_FIRMWARE_WORKAROUND? Then there's at
least some clue that we're in uncharted territory.

Guys, that last statement makes no sense.
The *real* hack was that original patch that caused problems.
I mean, just look at it. It has a completely made up - and bad -
default start, and then it tries to forcibly just create the maximum
window it possibly can. Well, not quite, but almost.
Now *THAT* is hacky, and fragile, and a bad idea. It's a fundamentally
bad idea exactly because it assumes
(a) we have perfect knowledge
(b) that window that wasn't even enabled or configured in the first
place should be the maximum window.
both of those assumptions seem completely bogus, and seem to have no
actual reason.
This comment in that code really does say it all:
/* Just grab the free area behind system memory for this */
very lackadaisical.
I agree that the 16GB guard is _also_ random, but it's certainly not
less random or hacky.
But I really wonder why you want to be that close to memory at all.
What was wrong with the patch thgat just put it the hell out of any
normal memory range, and just changed the default start from one
random (and clearly bad) value to _another_ random but at least
out-of-the-way value?
IOW, this change
- res->start = 0x100000000ull;
+ res->start = 0xbd00000000ull;
really has a relatively solid explanation for it: "pick a high address
that is likely out of the way". That's *much* better than "pick an
address that is right after memory".
Now, could there be a better high address to pick? Probably. It would
be really nice to have a *reason* for the address to be picked.
But honestly, even "it doesn't break Aaro's machine" is a better
reason than many, in the absence of other reasons.
For example, was there a reason for that random 756GB address? Is the
limit of the particular AMD 64-bit bar perhaps at the 1TB mark (and
that "res->end" value is because "close to it, but not at the top")?
So I think "just above RAM" is a _horrible_ default starting point.
The random 16GB guard is _better_, but it honestly doesn't seem any
better than the simpler original patch.
A starting point like "halfway to from the hardware limit" would
actually be a better reason. Or just "we picked an end-point, let's
pick a starting point that gives us a _sufficient_ - but not excessive
- window".
Or any number of other possible starting points. Almost _anything_ is
better than "end of RAM".
That "above end of RAM" might be a worst-case fall-back value (and in
fact, I think that _is_ pretty close to what the PCI code uses for the
case of "we don't have any parent at all, so we'll just have to assume
it's a transparent bridge"), but I don't think it's necessarily what
you should _strive_ for.
So the hackyness of whatever the fix is really should be balanced with
the hackyness of the original patch that introduced this problem.

Actually I don't want to be close to the end of memory at all. It's just
what I found a certain other OS is doing and I thought: Hey, that has
the best chance of working...
But yeah, thinking about it I agree with you that this was probably not
a good idea.

Well Bjorn didn't liked it because I couldn't come up with a good
explanation why 256GB is a good value in general (it is a good value for
our particular use case).

That is actually a hardware limit documented in the BIOS and Kernel
developers guide for AMD CPUs
(https://support.amd.com/TechDocs/49125_15h_Models_30h-3Fh_BKDG.pdf).
I should probably add a comment explaining this.

Well that is exactly what the 256GB patch was doing.
So as long as you are fine with that I'm perfectly fine to use that one.

Ok, good. So at least some of those values have reasons.
And yes, documenting it would be great.

Ahh, so 0xbd00000000ull is basically 256GB from the end point, and the
end point is basically specified by hardware.
So yes, I think that's a starting point that can at least be
explained: let's try to make it something "big enough" (and 256GB
seems to be big enough).
Of course, since this is all "pick a random number", maybe that breaks
something _else_.
We do traditionally have a very similar issue for the 32-bit PCI
starting address, where we used to have tons of issues with "we don't
know all resources, we want to try to come up with a range that is out
of the way".
There we try to find a big enough gap in th e820 memory map
(e820_search_gap()), and the end result is pci_mem_start (which is
then exposed as PCIBIOS_MIN_MEM to the PCI resource allocation).
If worst comes to worst, maybe we should look at having something
similar for the full 64-bit range.

Done, patches for this are in your inbox.
Additionally to that I cleaned up the 256GB patch a bit more, e.g. added
a comment where the 0xfd00000000 limit comes from and updated the commit
message.
Please review and/or comment,
Christian.
