[smartpqi updates PATCH 0/9] smartpqi updates

[Don Brace]

These patches are based on Martin Peterson's 5.14/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git 
      5.14/scsi-queue

Most of these patches consist of adding new PCI devices. The remainder
are simple updates to correct some rare issues and clean up some
driver messages.

This set of changes consist of:
  * Add in new PCI-IDs.
    5 of these patches are adding in new PCI-IDs.
  * Removing unnecessary unsupported feature messages.
  * Update copyright information.
  * Enhance reset messages.
    - Add SCSI command CDB[0] value to message.
    - Also check for a 0 length SCSI command that can occur if
      sg_reset is issued without any outstanding SCSI commands.
  * Clean up a rare initialization issue where interrupts are
    enabled before the supporting controller context has been
    fully initialized causing NULL pointer access.
  * Update the driver version to 2.1.10-020

[smartpqi updates PATCH 2/9] smartpqi: rm unsupported controller features msgs

[Don Brace]

From: Kevin Barnett <kevin.barnett@microchip.com>

Remove "Feature XYZ not supported by controller" messages.

During driver initialization, the driver examines the PQI Table Feature bits.
These bits are used by the controller to advertise features supported by the
controller. For any features not supported by the controller, the driver would
display a message in the form:
        "Feature XYZ not supported by controller"
Some of these "negative" messages were causing customer confusion.

As it’s info log level and not warning or notice, these message are 
useful in my opinion. You could downgrade them to debug, but I do not 
see why. If customers do not want to see these info messages, they 
should filter them out.

For completeness, is there an alternative to list the unsupported 
features from the firmware for example from sysfs?


Kind regards,

Paul

Don> Thanks for your Review.
At this time we would prefer to not provide messages about unsupported features. We may add them back at some point but we have taken them out of our out-of-box driver also so we hope to keep the driver code in sync.

[I corrected Martin’s email from peterson to peters*e*n. Don, you should 
have also receive a bounce message from the MTA. I guess Martin has 
these as a list subscriber nevertheless, but I suggest to resend the 
series as soon as possible.]

Dear Don,


Thank you for your reply.

Only because a customer complained? That is not a good enough reason in 
my opinion. Log messages, often grepped for, are an interface which 
should only be changed with caution.

If these absent feature message were present for a long time, and you 
suddenly remove them, people looking a newer Linux kernel messages, 
users conclude the feature is supported now. That is quite a downside in 
my opinion.

That’s why you should develop for Linux master branch and upstream 
*first* to get external reviews. That argument should not count for 
Linux upstream reviews in my opinion.

Don: It was many customers. Enough to have our customer support ask for the messages to be redacted. Also, some of the messages were erroneous causing yet more confusion. I'm sorry, but they have to be removed.

That’s why you should develop for Linux master branch and upstream
*first* to get external reviews. That argument should not count for Linux upstream reviews in my opinion.

Don: Thanks for your suggestion. Our model has a lot of internal reviews, then several weeks or more of testing before we add patches to the kernel. More automated tests are added daily. Any changes from the kernel community are included in our model.


Kind regards,

Paul

You also change the driver name. Maybe do that in a separate commit with 
a dedicated commit messages summary.

Name changes affecting strings showing up in log messages are always 
confusing for people’s muscle memory. No idea, if it’d be better to 
include both names in the driver name until the next Linux LTS series is 
released.

Don: I'll separate the driver name from the copyright patches and send up a new patch in V2.

Thanks for your review.


Name changes affecting strings showing up in log messages are always confusing for people’s muscle memory. No idea, if it’d be better to include both names in the driver name until the next Linux LTS series is released.

Don: We would rather just have one name.

Can you please mention the device ID and name in the git commit message, 
so it can be compared to the code change? See *[smartpqi updates PATCH 
1/9] smartpqi: add pci id for H3C controller* as an example.


Kind regards,

[smartpqi updates PATCH 8/9] smartpqi: fix isr accessing null structure member

[Don Brace]

From: Mike McGowen <mike.mcgowen@microchip.com>

Correct driver's ISR accessing a data structure member
that has not been fully initialized during driver init.
  - The pqi queue groups can be null when an interrupt fires.

Does that crash the Linux kernel?

If it fixes a crash(?), please add a Fixes: tag so it can be backported 
to the stable series.

 From a quick look, these two functions are quite different. It’d be 
great if you elaborated a bit in the commit message, what else the new 
function does.

Also, with this change, `pqi_request_irqs()` does not seem to have any 
users anymore. Without your patch:

     $ git grep pqi_request_irqs
     drivers/scsi/smartpqi/smartpqi_init.c:static int 
pqi_request_irqs(struct pqi_ctrl_info *ctrl_info)
     drivers/scsi/smartpqi/smartpqi_init.c:  rc = 
pqi_request_irqs(ctrl_info);

Don: 
No. I updated the title and description to reflect this. It resulted in some brief access to uninitialized members.
This was found during some internal testing, no bugs were ever filed for this change.
 
Thanks for your review.
