Hello list, cc Karthik,
I have recently upgraded the BIOS on an HP 8530p laptop (to version
F.0C), and am experiencing what sound like extremely similar SENTER
failures to those Hal is getting on his dc7800. I cannot do a
regression test, however, as the previous BIOS version did not support
SENTER at all on this system. This laptop does not have a serial port,
so all I can capture is the in-memory log from the system following
SENTER-inspired reboot (see attached).
The error code in the log decodes to "BARs in VT-d DMAR DRHD struct
mismatch".
Note that I believe Hal's dc7800 has a Q35 Express chipset, and this
laptop has "Mobile Intel PM45 Express Chipset ICH9M-Enhanced."
Interesting that the possibly similar / related failures are across
different chipsets.
In following along with attempting to debug Hal's system, I decided to
go ahead and disable Audio and USB Legacy Support in BIOS, and to attach
the output of `lspci -v` and Ross's dmardump.
I've copied Karthik from HP as he has previously been very helpful in
determining that there were issues with SENTER and the previous BIOS
version for this laptop.
I'm happy to execute additional tests to help track down the cause of
these problems.
Thanks to all for their time and suggestions,
-Jon

Hi
Great. However, I'm still curious about what caused it to fail. I hope
in the future more info will be released on what SINIT actually does.
As my last posts indicated, it probably isn't/wasn't an inconsistency
in the tables themselves, but rather an inconsistency with the tables
and something outside the tables, such as either the PCI device BAR
registers, or perhaps the register base of the DMA units that are off
(i.e. maybe these registers don't actually point to a DMA unit).
Best regards,
Martin Thiim

As an update, I successfully rolled back my BIOS to an earlier
version. With this change, tboot works again! GETSEC[SENTER] executes
with no errors and I get into the secure state. So it is definitely
some problem relating to the new BIOS.
Interestingly, I dumped the DMAR tables created by the working BIOS
and they are byte for byte identical to what they were with the
non-working BIOS. So clearly there is no point in going over those
tables with a fine tooth comb to figure out what SINIT doesn't like
about them. Something else must be different. I'd say the SINIT error
codes are not particularly informative about what is going wrong in
this case.
I hope the SINIT team will still look into this. I can easily go back
to the newer BIOS in order to reproduce the failing state. The new
BIOS has the advantage that I can reboot after an SINIT failure and
read the errorcode register. With the old BIOS, attempts to reboot
hang in the BIOS and it's not possible to read the errorcodes, which
made debugging TXT almost impossible.
So I can either use the new BIOS which would allow some debugging but
which unfortunately doesn't work with SINIT; or I can use the old BIOS
which works with SINIT but reveals nothing when there is a failure.
Neither is a great alternative.
