[PATCH 0/8] drm/client: Stop using legacy crtc->mode and a bunch of cleanups

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The most interesting part is the change to modes[] to solve
the lifetime issue so that we can stop using the legacy
crtc->mode for atomic drivers.

Additionally I included a bunch of cleanups, some of which were
inherited from https://patchwork.freedesktop.org/series/132051/

Ville Syrjälä (8):
  drm/client: Constify modes
  drm/client: Use array notation for function arguments
  drm/client: Streamline mode selection debugs
  drm/client: Make copies of modes
  drm/client: Stop using the legacy crtc->mode
  drm/client: s/new_crtc/crtc/
  drm/client: Move variables to tighter scope
  drm/client: s/unsigned int i/int i/

[PATCH 1/8] drm/client: Constify modes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The modes used by the client code live on the connectors' mode
lists, which are not owned by the client code, and thus it has
no business modifying the modes. Mark the modes const to make
that fact abundantly clear.

[PATCH 2/8] drm/client: Use array notation for function arguments

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use the array notation rather that the pointer notation for
function arguments. This makes it clear to the reader that
we are in fact dealing with an array rather than a single
pointer. Functionally the two are equivalent.

[PATCH 3/8] drm/client: Streamline mode selection debugs

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Get rid of all the redundant debugs and just wait until the end
to print which mode (and of which type) we picked.

[PATCH 4/8] drm/client: Make copies of modes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm_client_firmware_config() is currently picking up the current
mode of the crtc via the legacy crtc->mode, which is not supposed
to be used by atomic drivers at all. We can't simply switch over
to the proper crtc->state->mode because we drop the crtc->mutex
(which protects crtc->state) before the mode gets used.

The most straightforward solution to extend the lifetime of
modes[] seem to be to make full copies of the modes instead
of just storing pointers. We do have to replace the NULL checks
with something else though. Checking that mode->clock!=0
should be sufficient.

And with this we can undo also commit 3eadd887dbac
("drm/client:Fully protect modes[] with dev->mode_config.mutex")
as the lifetime of modes[] no longer has anything to do with
that lock.

Apparently this guy doesn't accept NULL, so this is oops central now.
I'll have to wrap these up a bit I guess.

[PATCH v2 4/8] drm/client: Make copies of modes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm_client_firmware_config() is currently picking up the current
mode of the crtc via the legacy crtc->mode, which is not supposed
to be used by atomic drivers at all. We can't simply switch over
to the proper crtc->state->mode because we drop the crtc->mutex
(which protects crtc->state) before the mode gets used.

The most straightforward solution to extend the lifetime of
modes[] seem to be to make full copies of the modes instead
of just storing pointers. We do have to replace the NULL checks
with something else though. Checking that mode->clock!=0
should be sufficient.

And with this we can undo also commit 3eadd887dbac
("drm/client:Fully protect modes[] with dev->mode_config.mutex")
as the lifetime of modes[] no longer has anything to do with
that lock.

v2: Don't try to copy NULL modes

I think it would be a lot better to first build that mode list while 
holding the mutex, and afterwards copy the resulting modes before 
releasing the lock. The code below is convoluted with drm_mode_copy().

A mode's clock isn't always known and not all drivers might set it 
correctly. At least in simpledrm/ofdrm, we have to make up a clock value 
for the firmware framebuffer. Otherwise some of our userspace would oops.

The test for clock != 0 makes sense, but it's maybe the wrong place to 
do this. Would a test for hdisplay/vdisplay != 0 work instead?

You're copying and only then test for validity?

My first thought was to make copies but still keep track
of pointers. That idea was a complete disaster because you
now had to carefully free the modes on the list.

I then considred some kind of double list approach, but that
too seemed more complicated/confusing than the (IMO fairly
straightforward) apporach I ended up with. I'd prefer to reduce
the nummber of arrays this thing uses rather than increase them.

That would work as well. drm_mode_validate_basic() rejects
everything with clock/hdisplay/vdisplay==0.

I thought drm_mode_copy() is a nop for NULL. Turns out I was wrong,
hence the v2.

For this specific case I suppose one could also write something like
 if (whatever_mode())
	drm_mode_copy(&modes[i], whatever_mode());
here, but having to repeat oneself is not so great.

We could of course avoid that with
 mode = whatever_mode();
 if (mode)
	drm_mode_copy(&modes[i], mode);
with the downside of needing yet another local
variable.

Had another look at the double array approach, and still
tought the result would be quite disgusting.

So I think the only other viable option is to keep the single
array of pointers, and stick copies onto it. But that introduces
more ways to leak memory and/or access already freed memory.
I don't really like the extra complexity that this requires.
It'd perhaps be more palatable if the whole thing would be
redesigned to be more AoS instead of SoA...

hi, Ville Syrjala,

we noticed there is a v2 for this commit
https://lore.kernel.org/all/20241003181553.8891-1-ville.syrjala@linux.intel.com/

but bot failed to analyze the patch mail structure and re-assemble it with
other patches in this serial to form a new branch (which need manual efforts).

so we just made this report out FYI. in case you are sure the issue should be
addressed by v2, please just ignore. if you want us to test v2, please let us
know. thanks

[PATCH 5/8] drm/client: Stop using the legacy crtc->mode

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

crtc->mode is legacy junk and shouldn't really be used with
atomic drivers.

Most (all?) atomic drivers do end up still calling
drm_atomic_helper_update_legacy_modeset_state() at some
point, so crtc->mode does still get populated, and this
does work for now. But now that the modes[] lifetime issues
have been sorted out we can just switch over to the
proper crtc->state->mode.

Rename the 'new_crtc' variable to just 'crtc' in

[PATCH 7/8] drm/client: Move variables to tighter scope

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Bunch of variables are only needed inside loops and whatnot.
Move them to a tighter scope to make the code less confusing.

Also replace the 'unsigned int i' footguns with plain signed
ints.

I moved that last part to a separate patch but forgot

[PATCH 8/8] drm/client: s/unsigned int i/int i/

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace the 'unsigned int i' footguns with plain old signed
int. Avoids accidents if/when someone decides they need
to iterate backwards.

Why are signed types preferable here?

If you iterate backwards you typically write

for (i = max; i >= 0; i--) {...}

and i>=0 is always true for unsigned types.

Another danger is doing any kind of arithmetic
with 'i' and expecting a signed result.

Based on my experience in getting burned by C integer
promotion/converison rules a good rule of thumb is to
always use just "int" unless there is a very good
reason for not doing so (eg. if the thing is a bitmask
or some kind of other thing where negative values
can never ever come up).

Also IIRC there was a Linus rant about "unsigned int i"
but I can't find it now.

Agreed.

An even worse antipattern is using u8 or u16 just because it's the
smallest type that is enough for the range or whatever. But then it ends
up being signed int arithmetic assigned back to the small unsigned type
anyway.
