[PATCH] amd64_edac - Add Family 17h Model 70h PCI IDs

[PATCH] amd64_edac - Add Family 17h Model 70h PCI IDs

[Isaac Vaughn]

Dear Mr. Petkov,

I noticed the current EDAC driver doesn't support the new Zen 2 (model 70h) processors, so I patched the new device ids in. The changes are minimal, I merely extended the existing enums with information from the new models.

This is my first kernel patch and I'm not sure I followed the guide (kernel.org/doc/html/v5.2/process/submitting-patches.html) correctly, so please let me know if I need to resubmit this email with updated formatting prior to review.

Sincerely,
Isaac Vaughn

Makes sense to me.

@Yazen, ACK?

Sure, you're almost there but it needs to have a title and a commit
message. If you need an example, look at how a similar patch to yours is
formatted:

6e846239e548 ("EDAC/amd64: Add Family 17h Model 30h PCI IDs")

Here's a web URL too in case you don't know how to work the git thing :)

https://git.kernel.org/linus/6e846239e5487cbb89ac8192d5f11437d010130e

That is, if you want to learn how to do patches at all. Otherwise, I can
fix it up for ya.

Leaving in the rest for Yazen.

You need to fix the tabbing here to look like the other struct
assignments above.

Here too. Your "else if" needs to have the same indentation as the one above.

And that too.

Depending on the text editor, you can show the whitespace characters on each
line and then make sure they're the same as on the lines above it. For example
with vim you do

":set list"

and that would show you:

^I^I} else if (pvt->model >= 0x30 && pvt->model <= 0x3f) {$ 
^I^I^Ifam_type = &family_types[F17_M30H_CPUS];$
^I^I^Ipvt->ops = &family_types[F17_M30H_CPUS].ops;$
^I^I^Ibreak;$
         } else if (pvt->model >= 0x70 && pvt->model <= 0x7f) {$
                 fam_type = &family_types[F17_M70H_CPUS];$
                 pvt->ops = &family_types[F17_M70H_CPUS].ops;$
                 break;$
^I^I}$


and you can immediately see the difference. We use tabs in the kernel,
which appear here as ^I and you have spaces, thus the difference in
indentation.

There's a checker script in the kernel source directory you can use:

$ ./scripts/checkpatch.pl /tmp/isaac.01
WARNING: please, no spaces at the start of a line
#34: FILE: drivers/edac/amd64_edac.c:2256:
+ [F17_M70H_CPUS] = {$

ERROR: code indent should use tabs where possible
#35: FILE: drivers/edac/amd64_edac.c:2257:

+         .f0_id = PCI_DEVICE_ID_AMD_17H_M70H_DF_F0,$

...

which would show you what is wrong with the patch.

And finally, here some more links which you might find useful:

https://www.kernel.org/doc/html/v5.2/process/coding-style.html
https://kernelnewbies.org/

That is, if you want to get involved in doing the patches thing :-)

Thx and have fun!

The new PCI IDs are correct. However, we also need Device 18h Function 3
for amd64_edac_mod to function. I don't see a commit upstream that adds
this.

Isaac,
Could you please add the Function 3 as well? Please see the following for
reference.

Thank you!

Re: [PATCH] amd64_edac - Add Family 17h Model 70h PCI IDs

[Isaac Vaughn]

Add the new Family 17h Model 70h PCI IDs (device 18h functions 0, 3, 4, and 6) to the kernel, the hwmon module, and the AMD64 EDAC module.

Changes to the amd64_edac were tested on 5.2.11 and the current patch was tested on 5.3.0rc7. Since git's pager has been mangling my indentation, diffs were generated with the '--no-pager' option. (Not sure if this might make output non-standard in some other way.)

That's probably because this is not how you generate patches with git.
Please have a look at one of the countless tutorials on the web how to
do that. The gist of it is, you do:

$ git commit -a -s
 <write commit message, add SOB etc>
$ git format-patch -1 -o /tmp/

and send the filename as an email or you use

$ git send-email -1 ...

depending on what you would like to do. Just note that git send-email
can spam people quickly so I'd suggest using the --dry-run option there
first. :)

The tutorials and the manpages of the respective commands will give you
more detail about what they all do and what options to use.

But before you do that, you need to fix your indentation because that
still is wrong. Use that script checkpatch.pl to verify your patch and
send it only then when it doesn't complain about spaces anymore, see
below.

Oh, and pls add those PCI IDs to drivers/edac/amd64_edac.h, not to
pci_ids.h because they will be used by the amd64_edac driver only for
now so they don't need to go into the system-wide header.

Thanks!

Does this apply to all the PCI IDs? Functions 0 and 6 are in amd64_edac.h, but some of the additional IDs had model 30h equivalents in different places. For the additional IDs Yazen pointed out, I imitated the changes from commit be3518a16ef270e3b030a6ae96055f83f51bd3dd (x86/amd_nb: Add PCI device IDs for family 17h, model 30h).

This applies to PCI IDs which are used by a single driver only. They
go in its header. If something else needs them, then they get moved to
pci_ids.h.

Since this ID is already defined, you don't need to add it again.

The code that searches for the PCI device will match on the ID and return a
pointer to the device. The name we associate with the ID is arbitrary. By
convention, we use the family/model where the ID first appears, but the
name itself isn't important.

Thanks,
Yazen

Ok, next lessons :)

Before you send a patch, do:

$ git diff | ./scripts/get_maintainer.pl

or if you've committed it already:

$ git log -p -1 | ./scripts/get_maintainer.pl

to know who to Cc.

I've added the respective mailing lists to Cc because this is a trivial
addition of PCI IDs and generally maintainers want to see it as an FYI
thing, thus Ccing the mailing list only. But you can just as well Cc the
maintainers too - they can manage the mail volume. :)

And last but *definitely* not least, the most important lesson: *always*
- I can't stress this enough - *always* build *and* test your patch
before sending:

If it is any consolation: we have all done this mistake in a hurry at

Ah, yes, you couldn't have known that, lemme explain.

So almost all maintainers have one or more branches which contain the
work scheduled to go to Linus in the next merge window and that work is
being merged on a daily basis into  linux-next.

The EDAC branch which has that is edac-for-next in the repo

git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git

Please use that one to base your patch on.

That branch also has a previous patch which does this:

-static int f17_base_addr_to_cs_size(struct amd64_pvt *pvt, u8 umc,
+static int f17_addr_mask_to_cs_size(struct amd64_pvt *pvt, u8 umc,

which explains the failure.

Thx.

Yeah, then you can send me only those changes against edac-for-next.
The driver won't load on Zen2 before the amd_nb.c changes have landed
upstream but that's fine - it's not like it did load before.

I made the changes against the git repo you linked and sent the patch.
The updated module didn't do anything when tested, but that seems to be
the expected behavior with the current amd_nb.
