[PATCH] hpsa: do not attempt to read from a write-only register

[Stephen M. Cameron]

From: Stephen M. Cameron <scameron@beardog.cce.hp.com>

Most smartarrays tolerate it, but a few new ones don't.
Without this change some newer Smart Arrays will lock up
and i/o will grind to a halt.

Noticed this wasn't in Linus's git tree yet, so resent it.

[BUG] scsi: hpsa: how to destroy your files

[Eric Dumazet]

Stephen,

Current linux-3.1-rc4+ is a total disaster on my BL460c G6


Few seconds after boot, I get "cmd_alloc returned NULL" messages
or "hpsa 0000:0c:00.0: resetting device 0:0:0:0"

Usually lot of files are corrupted, fsck needed, and full distro
reinstall as well.

I tested on two different machines, same result.

What kernel were you running successfully previously?

I saw similar on BL460cG7 on Friday with 3.1-rc4,
but I'm not sure the problem is in the driver.  
I installed rhel6.1, then put 3.1-rc4 on.  Turning off
"Virtualization" in the kernel config seemed to help
(allowed it to boot) and so I thought that must have
been the source of the issue.  So, you might try that.

However, I rebooted that machine just now, and
now I am getting the similar "hpsa 0000:0c:00.0: resetting device 0:0:0:0"
message, so that's pretty weird.

The cmd_alloc failure, I didn't see, but I may have missed it
(didn't have console directed to serial output.)

cmd_alloc failing is not generally expected, as we reserve enough
commands that the upper layers should never exhaust them all (should
honor hpsa's max request limit), so that's pretty weird that
you're seeing that.

I am able to run 3.1-rc3 on rhel6 just fine on other systems (DL380g7,
for example) and I don't think there are any hpsa changes between rc3
and rc4.  (haven't tried rc4 on the dl380g7 yet).

So, I'm not sure what's going on with the BL460c yet, but I am
aware of the problem and have already seen it.  I can't think of
any driver changes lately which should be causing such
changes in behavior.

I'll let you know if I can bisect before destroying (again) my distro

(I re-installed a fresh debian wheezy/sid)

    PCI: Set PCI-E Max Payload Size on fabric
    
    On a given PCI-E fabric, each device, bridge, and root port can have a
    different PCI-E maximum payload size.  There is a sizable performance
    boost for having the largest possible maximum payload size on each PCI-E
    device.  However, if improperly configured, fatal bus errors can occur.
    Thus, it is important to ensure that PCI-E payloads sends by a device
    are never larger than the MPS setting of all devices on the way to the
    destination.
    
    This can be achieved two ways:
    
    - A conservative approach is to use the smallest common denominator of
      the entire tree below a root complex for every device on that fabric.
    
    This means for example that having a 128 bytes MPS USB controller on one
    leg of a switch will dramatically reduce performances of a video card or
    10GE adapter on another leg of that same switch.
    
    It also means that any hierarchy supporting hotplug slots (including
    expresscard or thunderbolt I suppose, dbl check that) will have to be
    entirely clamped to 128 bytes since we cannot predict what will be
    plugged into those slots, and we cannot change the MPS on a "live"
    system.
    
    - A more optimal way is possible, if it falls within a couple of
      constraints:
    * The top-level host bridge will never generate packets larger than the
      smallest TLP (or if it can be controlled independently from its MPS at
      least)
    * The device will never generate packets larger than MPS (which can be
      configured via MRRS)
    * No support of direct PCI-E <-> PCI-E transfers between devices without
      some additional code to specifically deal with that case
    
    Then we can use an approach that basically ignores downstream requests
    and focuses exclusively on upstream requests. In that case, all we need
    to care about is that a device MPS is no larger than its parent MPS,
    which allows us to keep all switches/bridges to the max MPS supported by
    their parent and eventually the PHB.
    
    In this case, your USB controller would no longer "starve" your 10GE
    Ethernet and your hotplug slots won't affect your global MPS.
    Additionally, the hotplugged devices themselves can be configured to a
    larger MPS up to the value configured in the hotplug bridge.
    
    To choose between the two available options, two PCI kernel boot args
    have been added to the PCI calls.  "pcie_bus_safe" will provide the
    former behavior, while "pcie_bus_perf" will perform the latter behavior.
    By default, the latter behavior is used.
    
    NOTE: due to the location of the enablement, each arch will need to add
    calls to this function.  This patch only enables x86.
    
    This patch includes a number of changes recommended by Benjamin
    Herrenschmidt.

Hi Eric,

I guess it would be useful to see "lspci -vv" output with a "good" kernel
and with that bad patch applied.  Most likely we should see some difference
somewhere in the MaxPayload fields in the PCI Express capability of
some device.

Either the RAID controller or something else lies, and puts a value
in the DevCap that it can't actually support, or else the patch is
buggy and puts something out of range in a DevCtl somewhere.

 - R.

While we investigate, I think the problems produced by the patch (data
corruption) are serious enough to warrant reverting it, please Jesse.

Thanks,

James

Yep, I just got another report about it today too, I'll queue the
revert.

Hm I haven't been paying attention to the compromise thread; how should
I share these changes?  Is master.kernel.org down indefinitely?  Is
there a new server at kernel.org I can use?

Can you try the attached patch and verify that it also resolves the

I cannot say that right now, as it appears the last "bad" kernel
destroyed my distro enough that I cannot test this patch without a full
reinstall. (/root partition is busted, even after several fsck -f -y)

[   42.501569] EXT3-fs error (device cciss/c0d0p1): ext3_free_inode: bit already cleared for inode 424649
[   42.501721] Aborting journal on device cciss/c0d0p1.

[   42.529563] EXT3-fs error (device cciss/c0d0p1) in ext3_delete_inode: IO failure


 I'll have to do this reinstall when I am at the office, in a couple of
hours.

I tested this patch and can confirm this solves the corruption problem.

But my disk is _much_ slower than before

# hdparm -t /dev/sda1

Before :

 Timing buffered disk reads: 254 MB in  3.02 seconds =  84.16 MB/sec

After :

 Timing buffered disk reads: 120 MB in  3.04 seconds =  39.42 MB/sec

Hmm, this speed regression is probably old : the 84MB/s was with the
standard debian 6.0.2 kernel (2.6.32-5-amd64)

This regression might be due to these two patches:

	d0be5ec8693944c2e2fc0de70fda9dbc1b93bd7d
	[SCSI] hpsa: do readl after writel in main i/o path to ensure commands don't get lost.

	Apparently we've been doin it rong for a decade, but only lately do we
	run into problems.
and
	fec62c368b9c8b05d5124ca6c3b8336b537f26f3
	[SCSI] hpsa: do not attempt to read from a write-only register

	Most smartarrays tolerate it, but a few new ones don't.
	Without this change some newer Smart Arrays will lock up
	and i/o will grind to a halt.

with the second patch being a correction to the first.

It seems like the readl after the writel should not be needed,
and wasn't needed for a very long time, but there is some very
hard to trigger and not yet well understood problem in which very
occasionally a command would get lost and the driver thinks a 
command is out, but controller firmware thinks all commands are
completed -- a circumstance which tends to make things grind to
a halt.

Those two patches avoid that problem.

Sorry, I cant provide a "lspci -vv" on a bad kernel, my machine locks
hard before I can type anything.

Here is the output on a "good" kernel

Thanks.  I will run this information by the hardware guys here
and see if they have any bright ideas.

Would be interesting to see if the "pcie_bus_safe" option 
makes a difference.

FWIW, this option does not help (though it does change the
behavior).  I get hpsa complaining about bad tags returned
from the hardware, which is to say, this code from hpsa.c
fires:

	static inline int bad_tag(struct ctlr_info *h, u32 tag_index,
		u32 raw_tag)
	{
		if (unlikely(tag_index >= h->nr_cmds)) {
			dev_warn(&h->pdev->dev, "bad tag 0x%08x ignored.\n", raw_tag);
			return 1;
		}
		return 0;
	}

I had added "pcie_bus_safe" and "pci.pcie_bus_safe" to the command
line parameters.  (Was hard to tell how it was supposed to be used
as there is nothing in Documentation directory that mentions 
pcie_bus_safe.)
