The first dump of the error message looks normal.

The 2nd -

Hardware Trace:

    0 Target : <0x00004a44> { _trap_c + 0x0 }

      Source : <0xffa00c38> { _evt_ivhw + 0x8c } CALL pcrel

    2 Target : <0xffa00bac> { _evt_ivhw + 0x0 }

      Source : <0x00013c1a> { ___do_softirq + 0x36 } STI R0

The "STI R0" instruction right before the jump to _evt_ivhw, means

that you need to turn on "CONFIG_DEBUG_HWERR" to understand where the

problem is coming from.

Can you turn that on, and recreate?

Thanks

I use trunk and 2009R1-rc5 toolchain, I can't reproduce it.

I need your kernel .config file to retry.

After tried 3 times, the kernel panic.

--- Graf Yang                                                2009-04-22 22:19:58

traps_test 18 should cause exception 0x2c icplb_miss, but it caused 0x3f

(hardware error), and the seqstat contains 0xc000(External Memory Addressing

Error). This is because the test app have the code,

P1 = [P2]; /* p2==0x87654320 */

The same code caused 0x26 (dcplb_miss) on BF537.

Who knows why they have this difference?

0x3f error will cause kernel panic after tried several times. So this is indeed

the bug.

--- Graf Yang                                                2009-04-22 22:51:29

Hi, Robin,

It failed at the 5th time running traps_test 18, would the followed information

be helpful?

The 4th, successful,

What version of 533 are you testing on?

05000246 (BF533-0.[0-4])- says: When Data CPLBs are enabled, hardware errors

generated as a result of speculative accesses to reserved or undefined memory

should not occur, but they do.

WORKAROUND:

None. Avoid accessing reserved memory as part of a speculative fetch.

If this is the problem - I can add something in traps.c to handle the anomaly.

--- Graf Yang                                                2009-04-24 07:17:40

I'm using 533 0.3

The trap_c() seems safe, it didn't trigger new hardware error in the first

hardware error handler.

I guess the processor sometimes not clear IPEND bit 5 (Hardware Error) in the

state translation from { _evt_ivhw + 0xec } RTI

                    to { _evt_timer + 0x0 }.

So once the __common_int_entry opened interrupt, the hardware error comes

again.

After add a ssync before reti, the hardware error trap test becomes very

stable.

Any idea?

Do you get a different result on 0.5 533?

-Robin

--- Graf Yang                                                2009-04-28 01:01:21

We have not 0.5 533 here. I tested it on 0.4 533, the ssync( or csync, or two

NOPs) also can fix this issue.

While, there is another issue on 0.4 533. The system will random hang when

testing the hardware error, may hang on the 8th, or the 19th, which I ever saw

on 0.3 533(when doing hardware error testing), and 0.2 537(when doing dcplb miss

testing). But it is frequently on 0.4 533.

Adding a random SSYNC/CSYNC so that a problem goes away isn't a "fix"

until someone from design confirms it is the the right thing to do - all that

could be happening is that the problem is less likely to occur - but could still

be there.

I'm following up with the design team.

-Robin

--- Mike Frysinger                                           2009-04-29 13:16:41

the PRM/HRM talks about too fast interrupt handlers need to use a sync

instruction, but that's due to the event handler needing to clear a bit in the

system MMR space.  i'm not sure that applies (directly) here since on the BF53x,

there is no bit to clear for IVG5 (hardware error) like there is on the BF54x.

--- Robin Getz                                               2009-04-30 15:37:57

After talking to the design folks, they suggested this (which is required, and

not in the HRM).

Since this isn't a fast path - it looks to be the safe thing to do.

I'm trying it out now, and it seems to work OK. (at least the last 30 min of

If no objections, I'll commit this to trunk tomorrow.

i guess the common irq code cant handle that since IVG5 is a dedicated entry

point rather

why do you do "R1 = R0" ?  R1 isnt used before it gets set directly

to 0x0020.

there is already P2 = IPEND below, so you should combine the IPEND loading

there as well

and i see we have '#' comments ... they should all be /*...*/

rather than 0x0020, how about EVT_IVHW ?

in terms of what's actually going on, why does mucking with IMASK matter when

clearing bits in ILAT ?

My guess is that the :

(_ex_dcplb_miss + 0x5e } RTX

instruction was pointing to (the value of the RTX) the one that caused the bad

fetch. (which would signal the IRQ5) - but even though it didn't commit, it was

put out on the bus. - when interrupts were re-enabled - it triggered...

I think there is something we can do in __common_int_entry which I'll try out -

the question is - do it unconditionally, or only if debug is enabled... Hmmm...

I guess I need to make sure the concept is sound with design before I start

noodling about making it conditional...

if it's a debug option, people wont enable it, and we'll debug stuff and users

will ask questions

--- Robin Getz                                               2009-05-01 14:02:24

It is really about making hardware errors less defered - which is the same as

the existing:

config DEBUG_HWERR

        bool "Hardware error interrupt debugging"

        depends on DEBUG_KERNEL

        help

          When enabled, the hardware error interrupt is never disabled, and

          will happen immediately when an error condition occurs.  This comes

          at a slight cost in code size, but is necessary if you are getting

          hardware error interrupts and need to know where they are coming

          from.

How about decouple this from DEBUG_KERNEL - and always turn it on for our

boards?

I like it always be enabled.

I can't run traps_test 24. Which item are you testing?

I'm running the following command on 0.3 bf533.

i=0; while [ 1 ] ; do traps_test 21 > /dev/null ; i=`expr $i + 1`; echo $i;

done

I use the latest kernel with your patch, it can never run over 100 times.

The hardware trace is,

It is the bug [#5101] which I'm tracking.

Are you using 0.5 bf533?

--- Mike Frysinger                                           2009-05-04 13:35:16

i thought DEBUG_HWERR was about better error messages, not correctly

functioning.  this is about hardware errors being correctly handled.

--- Graf Yang                                                2009-05-04 23:24:02

Robin is working on this bug.

--- Robin Getz                                               2009-05-11 16:11:50

So, I think I will revert this change, and marked closed -- as I think the

corrections in bug 5120 are the right ones, and the csync masks things a bit..
