5.2 hppa merge seems to work on my machines

[Meelis Roos]

Just tested v5.1-5445-g80f232121b69 git on A180c, rp2450, rp2470, rp3410 and rp3440 and
it seems to work everywhere for me.

Great!
Thanks for testing, Meelis!

hi
guys, unfortunately, it panics with Marvell MV88SX6081 sata controller.
I will publish more details later

I am testing a few sata controllers, see here

In one of our buildds we use a
Silicon Image, Inc. SiI 3112 Serial ATA Controller (rev 02)
PCI card.
I'm not sure if it's fast, but at least it seems somewhat stable.

This Syba card also works:
00:01.0 RAID bus controller: Silicon Image, Inc. SiI 3124 PCI-X Serial ATA Controller (rev 02)

I've added both to a new Wiki section "SATA Controllers":

You can add this one:

40:03.0 RAID bus controller: VIA Technologies, Inc. VT6421 IDE/SATA Controller 
(rev 50)

I have been using it for years, first in my C3600, now in my C8000.

Re: 5.2 hppa merge seems to work on my machines

[Carlo Pisani]

guys, bad news!
as described here (1) we are testing several sata controllers by a script that
1) copy a very big file cp data_16GB.bin copy.bin
2) compare the md5sum for checking the integrity

we have a couple of SIL24 controllers, and they both work but only
with small files <8Gbyte
trying to copy a big file, 16GB, results in the following HPMC error

A Data I/O Fetch Timeout occurred while CPU 0 was requesting
information from a device at the path 10/6/2/0 (PCI slot 2).

I have uploaded a ser-pim-log there for more details, it's related to
the Marvell MV88SX6081's sata controller, but I have the same behavior
with a Silicon Image Sil3124 controller

I am on the last kernel v5.1 from the git repository.

Performances are, in both cases, very low: something about
10Mbyte/sec, which is ... really too low

Tomorrow I will try the old 4.16, which I remember to be more stable
with the SIL24 controller.

(1) http://www.downthebunker.com/reloaded/space/viewtopic.php?f=50&p=1618

p.s.
has anyone ever tried an FC adapter on an FC-bridge?

I don't see problem on my c8000:

Note card is PCIX slot.

> Note card is PCIX slot.

tested on a C3600
with a Silicon Image Sil3124
the first card's brand is "SYBA-II" (from Amazon dot com)
it's 4 SATA channels, PCI 32bit

the second card's brand is "Adaptec 1210SA"
it's a 2 SATA channels, PCI 32bit

we do not have a PCI 64bit Silicon Image Sil3124

which is your card's brand?

are you using PCI-hardfail ? or softfail?
do you have CONFIG_MLONGCALLS=y ?

unfortunately, we do not have a C8000 to test

There is also this card with Silicon Image Sil3512:
https://www.sybausa.com/index.php?route=product/product&product_id=171&search=SD-SATA150R
https://www.amazon.ca/Syba-Controller-Silicon-Software-Components/dp/B000BU7XNG?th=1
Keying looks universal.

Problems from test like this suggest a problem outside the libata drivers themselves.

To me, it sounds rather something like dma mapping/sync errors, or memory
management errors (possibly dependent on hppa bus(bridge types).

It's not installed in our C3600 at the moment,
but it seems what we observed 2 days ago with Highpoint RocketRAID
1640HTP374 card
it's PCI 32bit, 4 SATA channels, it doesn't crash, but it randomly
offers file corruptions.
The dmseg shows a lot of DMA errors.

How to investigate? I am not a kernel developer, but rather an HDL-guy (FPGA)

I agree.  The memory errors in the PIM dump are recorded by the PDC firmware and they don't
directly involve the linux drivers.  Might be hardware problem.

which kind of error problem?

those two cards have no problem when tested on PowerMac-G4
and we have a second C3600, reporting the same behavior

so, supposing those cards are OK, and C3600s are OK
what might be wrong about the hardware?
