[PATCH v2 0/8] drm/xe: CRI support in gt_throttle + refactors

[PATCH v2 0/8] drm/xe: CRI support in gt_throttle + refactors

[Lucas De Marchi]

First patch was extracted from the rest of the CRI support series:
https://patch.msgid.link/20251021-cri-v1-0-bf11e61d9f49@intel.com

I did some minor tweaks for a v2 of that patch: something that could be
considered for merging since it follows the style of that file.

Patches on top are refactors to simplify the code and reduce its
verbosity/boilerplate.

Finally last patch tries to resolve the TOCTOU issue previously
discussed in a reasonable way.

Changes in v2:
- Handle comments on v1, noted on individual patches
- Improve documentation, adding it to the html output
- Add patch to introduce status_reasons attribute to overcome the TOCTOU
  of the current API
- Link to v1: https://patch.msgid.link/20251023-gt-throttle-cri-v1-0-9f36f3c8861c@intel.com

[PATCH v2 1/8] drm/xe/cri: Add new performance limit reasons bits

[Lucas De Marchi]

From: Sk Anirban <sk.anirban@intel.com>

Crescent Island has some additional and different bits for performance
limit reasons. Add the new definitions and use them for CRI.

[PATCH v2 2/8] drm/xe/gt_throttle: Tidy up perf reasons reading

[Lucas De Marchi]

There's no need to be so verbose with two functions per bit:
read_reason_xxxxx() and reason_xxxxx_show(). Drop the former and just
use a new is_throttled_by() that receives the mask as parameter.

[PATCH v2 3/8] drm/xe/gt_throttle: Always read and mask

[Lucas De Marchi]

Use a single function to read and mask the value the callers will be
interested in. This reduces the risk of a caller using a plain call to
xe_gt_throttle_get_limit_reasons() without applying any mask, which can
return unexpected bits for future platforms.

Select which reg and mask it's going to be used according to the
platform and gt type and always use that one function.

There was an odd xe_gt_dbg() when reading the status, which is not done
for any other throttle/* sysfs file, so just make the status be as
special as everybody else.

[PATCH v2 4/8] drm/xe/gt_throttle: Add throttle_to_gt()

[Lucas De Marchi]

Reduce boilerplate code by adding a helper to go directly from the
throttle kobject to the gt. Note that there's already a kobj_to_gt(),
but that actually converts our kobj_gt object to gt.

[PATCH v2 5/8] drm/xe/gt_throttle: Tidy up attribute definition

[Lucas De Marchi]

Move the attribute definitions to be grouped together rather than near
the show() function: checkpatch keeps complaining about the missing
newline when defining new attributes and it reads better to group
everything, which should match e.g. the xe_pmu.c style.

While grouping them, also define a THROTTLE_ATTR_RO(), similar to
DEVICE_ATTR_RO(), and use it to define all attributes. This makes it
shorter and with a familiar syntax.

Finally, during the cri_throttle_attrs[] array definition, also
highlight what's coming from common attributes and what is CRI-specific.

These 3 things could be done as separate commits, but they are all about
the same thing: reduce the attribute definition verbosity and are very
simple and mechanical.

[PATCH v2 7/8] drm/xe/gt_throttle: Drop individual show functions

[Lucas De Marchi]

They are all doing the same thing with the mask being the param. Just
declare our own attribute to store the mask and provide a single
function.

Another common pattern is to define the show function in the macro,
however on follow up work the mask may be used for returning more
information, so it'd need to be stored in any case.

[PATCH v2 8/8] drm/xe/gt_throttle: Avoid TOCTOU when monitoring reasons

[Lucas De Marchi]

It's currently not possible to safely monitor if there's throttling
happening and what are the reasons. The approach of reading the status
and then reading the reasons is not reliable as by the time sysadmin
reads the reason, the throttling could not be happening anymore.

Previous tentative to fix that[1] was breaking the ABI and potentially
sysadmin's scripts. This takes a different approach of adding and
documenting the additional attribute. It's still valuable, though
redundant, to provide the simpler 0/1 interface.

In order to avoid userspace knowledge on the bitmask meaning and to be
able to maintain the kernel side in sync with possible changes in
future, just walk the attribute group and check what are the masks that
match the value read.

Thanks for looking into this, but following the recent developments on [2]
I'm beginning to have my doubts about this.

I don't have any strong opinions but we can probably hold on to this one
until we reach some conclusion on the matter.

what's the relation between that patch and this one? If it's about
multiple values in a single attribute, then they are not really at the
same level:

Compare this:
	pl1
	pl4

To that:
	Capability Info: 0x138320 - 0x2001ae06
	Postcode Info: 0x138324 - 0x0
	Overflow Info: 0x138328 - 0x0
	Auxiliary Info 0: 0x13832c - 0x0

And from Documentation/filesystems/sysfs.rst:

	Attributes should be ASCII text files, preferably with only one value
	per file. It is noted that it may not be efficient to contain only one
	value per file, so it is socially acceptable to express an array of
	values of the same type.

	Mixing types, expressing multiple lines of data, and doing fancy
	formatting of data is heavily frowned upon. Doing these things may get
	you publicly humiliated and your code rewritten without notice.

I'd say the array of "reasons" in this patch clearly matches the first
paragraph: it's the same type, not fancy formatting and has a reason to
exist: TOCTOU mentioned in the docs and commit message). Another thing
that I consider important: not expose the raw number to userspace so it
doesn't have to decode the bitmapp per platform in userspace (the
platform abstraction belongs in the kernel) and is easy to maintain for
new platforms (hence the walk over the attribute_group).

The capability stuff on the other patch is much closer to the second
paragraph.

Let me discuss this with Anirban if there are any particular caveats

Perhaps add something like: TOCTOU (time-of-check to time-of-use).

ok... just to be clear, this is not about any security issue that
sometimes the TOCTOU abbreviation is associated with, it's just a
"normal bug/race" in the interface.

I'm lazy and I don't like the additional space that the lazy approach
would cause in the last entry :-/. For printing arrays to sysfs
doesn't seem there's a uniform approach. Some use \n and some use
space.

do we care about the extra space? if not, then it would be:

	ret += sysfs_emit_at(buff, ret, "%s ", (*pother)->name);

if we do, then:

	ret += sysfs_emit_at(buff, ret, "%s%s", ret ? " " : "", (*pother)->name);
or
	ret += sysfs_emit_at(buff, ret, "%.*s%s", !!ret, " ", (*pother)->name);

For the simplicity (lazyness?!) I believe we should go like this
and then an extra \n after like done in
show_scaling_available_governors() at drivers/cpufreq/cpufreq.c

commit 518e6112a32408998b8e7d9e62fe8c90bc46d747
Author: Lucas De Marchi <lucas.demarchi@intel.com>
Date:   Sun Oct 26 22:57:20 2025 -0700

    drm/xe/gt_throttle: Avoid TOCTOU when monitoring reasons
    
    It's currently not possible to safely monitor if there's throttling
    happening and what are the reasons. The approach of reading the status
    and then reading the reasons is not reliable as by the time sysadmin
    reads the reason, the throttling could not be happening anymore.
    
    Previous tentative to fix that[1] was breaking the ABI and potentially
    sysadmin's scripts. This takes a different approach of adding and
    documenting the additional attribute. It's still valuable, though
    redundant, to provide the simpler 0/1 interface.
    
    In order to avoid userspace knowledge on the bitmask meaning and to be
    able to maintain the kernel side in sync with possible changes in
    future, just walk the attribute group and check what are the masks that
    match the value read.
