[Intel-gfx] [PATCH 01/10] drm/i915: Check for nomodeset in i915_init() first

[Daniel Vetter]

When modesetting (aka the full pci driver, which has nothing to do
with disable_display option, which just gives you the full pci driver
without the display driver) is disabled, we load nothing and do
nothing.

So move that check first, for a bit of orderliness. With Jason's
module init/exit table this now becomes trivial.

[Intel-gfx] [PATCH 02/10] drm/i915: move i915_active slab to direct module init/exit

[Daniel Vetter]

With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_cache to just a slab_cache.

[Intel-gfx] [PATCH 05/10] drm/i915: move gem_context slab to direct module init/exit

[Daniel Vetter]

With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_luts to just a
slab_luts.

[Intel-gfx] [PATCH 08/10] drm/i915: move scheduler slabs to direct module init/exit

[Daniel Vetter]

With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_dependencies|priorities to just a
slab_dependencies|priorities.

[Intel-gfx] [PATCH 09/10] drm/i915: move vma slab to direct module init/exit

[Daniel Vetter]

With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_vmas to just a
slab_vmas.

We have to keep i915_drv.h include in i915_globals otherwise there's
nothing anymore that pulls in GEM_BUG_ON.

It's a bit ugly to go to a design where i915_pci.c has to include so 
many random parts of i915. IMO for a complex driver like i915, 
compartmentalizing so much knowledge about the internals was better 
inside the globals layer.

Maybe add a cover letter to explain the perceived pros and cons and 
thinking in general?

Regards,

Tvrtko

static?  Or were you planning to expose it somehow?  With that fixed,

I agree that i915_pci feels like the wrong place to put this but I
don't think that's so much because globals don't belong in i915_pci
but because i915_init/exit don't belong there.  Maybe, once this is
all said and done (or at the start of the series), we should move
i915_init/exit to i915_drv.c?  Of course, there's a bunch of PCI
probing stuff in i915_drv.c so..... yeah.... our organization is
pretty busted.

To put a finer point on this, the new "design" is really to have a
single flat list instead of two, one nested inside the other.  There's
nothing wrong with that at all.  The fact that all this stuff now
lives in i915_pci.c is ugly.  But, as I said, that's kind-of an
accident of history because that's where i915_init() and i915_exit()
currently live.  We should just move the lot to i915_drv.c.

Indentation is wrong here

With static and indentation fixed,

Hmm.. on one hand it does sounds better to move to i915_drv.c, but is it 
just because all these new include directive are so visibly out of place 
in i915_pci.c?

Perhaps we need i915_module.c and then i915_globals is a completely fine 
concept. Desired IMO even since we have to avoid globals in general 
(multi-gpu) so it sticks out nicely that all that is allowed to be 
global has a special place.

And i915_drv.c can remain being about a driver instance as bound to one GPU.

That feels like the best of both worlds to me.

Is i915_drv.c about a single instance bound to a single GPU?  If so,
then, yeah, maybe not the right place.  Maybe a i915_module.c would be
better.  It's all different shades of shed paint.

Yep, all functions there either take drm_dev, pdev or dev_priv as 
argument, or return/initialize dev_priv.

Hm not really just different shades IMO. Because I argue the patch 
series as is is a retrograde step in the above discussed respect.

I think i915_globals is cleaner code organisation. Because even if we 
add i915_module.c, then that can be made initialize globals and register 
with pci in cleanly separated steps without the need to include many 
driver internals.

I see r-b are accumulating but I hope reasonable objections will be 
considered.

Ok, so maybe I'm missing something in what you're saying.  I was under
the impression that your primary concern was separating PCI setup from
per-device from per-module stuff.  If so, moving it all to an
i915_module.c fixes that.

Are you arguing that a flat list of module init steps is bad?  And
that having globals be its own sub-list is good?  If so, then I have
to disagree.  I don't think splitting the calling of misc "set up my
slabs" functions from the final "register with PCI" at the end gains
us anything.  What it does do is give more files to search through,
more layers to think about when understanding the code, and more
infrastructure to maintain.

If, on the other hand, we had a globals infrastructure that actually
gained us something in terms of code simplicity, I might be able to
get behind that.  For instance, I could imagine something like this:

I915_DECL_SLAB(foo);

   /* Someone allocates something */
   kmem_cache_alloc(foo.slab);

where we somehow automagically declare the slab, initialize it on
module load, and tear it down on module exit.  That would add real
value.  As is, all i915_globals.c adds is extra layers.

Yeah, but i915_module.c was just a side discussion which started from 
whether it is right or not to put module init into i915_drv.c. It does 
not fix the fundamental question of the below discussion.

I think having to include all the driver sub-sub component headers from 
any top level module init file is a step towards a worse design. 
Currently those steps were nicely encapsulated and I don't see a reason 
to break them out to top level.

I read this as a statement that at least one part of your thinking is 
that current globals code is too verbose for simple global slab usage?

This I can buy, given how all but two usages are creating a single slab. 
Then there are two callers which use two slabs, but nothing outside the 
slab territory. So argument to simplify can be made yeah, only question 
is how.

Simple macro like you suggest sounds very attractive indeed if it could 
replace boiler plate code for single slab users (albeit with some more 
arguments). Problem is I don't know that we could make it call a 
registration helper from global scope.

Hm removing the list and going for fixed table slots might work, if 
logistics of reserving indices for it in i915_globals.h wouldn't be too 
ugly? Hm maybe not too ugly, maybe it is just an enum every global slab 
users adds for themselves and references it in a macro. With macro magic 
like DEV_INFO_FOR_EACH_FLAG and company to generate the table etc?

I think if we want it a new i915_module.c for the module stuff makes more
sense. And leaving the pci driver in i915_pci.c. At least imo i915_drv is
about the drm_driver instance ...

I'll see what it looks like for v2.
