Dear Linux folks,
Linux 4.19.13 from Debian Sid/unstable logs the message below on the

As a result, the early time stamps do not seem to be working.

And the further boot log says:
[ 0.036000] tsc: Unable to calibrate against PIT
[ 0.036000] tsc: using HPET reference calibration
[ 0.036000] tsc: Detected 3500.117 MHz processor
So the quick calibration in early boot fails because the PIT seems not to
do what the kernel expects. Nothing we can cure :(
Thanks,

I see. Can AMD confirm that this is the expected behavior? If yes, should
the fast TSC calibration be skipped on these devices?
Kind regards,

It should work and we really don't want to add cpu family/model based
decisions whether we invoke something or not. Those tables are stale before
they hit mainline.

Understood. If it’s supposed to work, any hints on how to debug this?
Does some Linux kernel developers have an AMD Ryzen system, and can reproduce
the issue?
It seems to fail with an AMD Ryzen 2400G too [1].
It also fails on an AMD Ryzen 7 1700 [2].

How to continue from here? Is documentation for that available from AMD?
I didn’t find a BKDG (Bios Kernel Developer Guide) at [3].

Hi Paul,
It's not expected behavior. All of the systems that I have access to do
not exhibit this issue. Having said that, I have a limited number of
systems available to me.
I don't have much experience in this area, but if it is something that
consistently occurs, you might try to see if you can better identify why
it fails. The message is issued in pit_hpet_ptimer_calibrate_cpu() in file
arch/x86/kernel/tsc.c.
Thanks,
Tom

But as a data point, what Ryzen systems did you test with? Just to know, if
there are configurations where the same processor behaves inconsistently.
Can you request one of the failing systems mentioned below to reproduce the
problem?

With the attached patch applied, I get:
[ 0.000000] tsc: quick_pit_calibrate: break in if !pit_expect_msb, i = 42
[ 0.000000] tsc: Fast TSC calibration failed, i = 42
[ 0.000000] tsc: Using PIT calibration value
The functions `pit_verify_msb()` and `pit_expect_msb()` are:
```
static inline int pit_verify_msb(unsigned char val)
{
/* Ignore LSB */
inb(0x42);
return inb(0x42) == val;
}
static inline int pit_expect_msb(unsigned char val, u64 *tscp, unsigned long *deltap)
{
int count;
u64 tsc = 0, prev_tsc = 0;
for (count = 0; count < 50000; count++) {
if (!pit_verify_msb(val))
break;
prev_tsc = tsc;
tsc = get_cycles();
}
*deltap = get_cycles() - prev_tsc;
*tscp = tsc;
/*
* We require _some_ success, but the quality control
* will be based on the error terms on the TSC values.
*/
return count > 5;
}
```
So count is smaller than or equal to 5, and `pit_verify_msb(val)` failed early,
right?

Depends on what you mean by "failed early." The loop iterated 42 times
as it tried to reach the acceptable error rate, so pit_expect_msb() had
succeeded a number of times before failing.
One of the things I noticed while searching for info on the PIT is that
one of the specs [1] mentioned that just reading the counter values (as
opposed to using the counter latch command or the read-back command) could
return undefined values if the counters are being updated while being
read. I'm not sure if that is what is occurring or if that matters in
this day and age, I'm not familiar with this area.
There's also talk of SMIs messing with this calibration. Could a long
running SMI (something close to 214us) run that results in keeping "count"
under 6? Again, just speculation on my part.
Thanks,

The maximum is 233, and in my tests the counter `i` never surpassed 55 or so.

I printed the values read from `inb(0x42)`, and log them, if they are unequal.
Please find the patch attached.
Here are the results of five boots.

So you can see, that, if my patch does not have any side effects, the
read value is in the end smaller than the expected value and decreases
not by one, but by more than one.
So in the last boot from e9 to e6, and the code decreases by one, so
expects e8 in the next iteration.
Of course your explanation that an SMI could cause this, could still
apply. Another explanation would be, that the PIT(?) does not decrease
by a constant rate.
I remembered that there was also a TSC related problem in coreboot,
that Google fixed by the commit below [2].

The HP and MSI firmwares take more than eight seconds though, compared
to the less than one second by coreboot, so it might be something else.
Unfortunately, I have neither resources nor knowledge to look into this,
and it looks like a hardware issue to me, only AMD can debug. Tom, could
you forward that to the appropriate departments in AMD?
Kind regards,
