[PATCH 0/3] drm/ttm, drm/xe: Consolidate the Buffer Object LRU walks

[PATCH 0/3] drm/ttm, drm/xe: Consolidate the Buffer Object LRU walks

[Thomas Hellström]

This is a deferred task from the Xe bo shrinker addition.

TTM currently have two separate ways of doing buffer object LRU
walks, of which one is exposed to drivers. Both have their benefits
but we shouldn't be implementing the complex bo locking in
two different places. So implement the ttm_lru_walk_for_evict()
function in terms of the guarded iteration also exposed to drivers.

This means that when we get to implement locking using drm_exec,
we only need to do that in a single place.

Add ticketlocking support to the guarded iteration and modify
the iteration arguments.

Thomas Hellström (3):
  drm/ttm: Use a struct for the common part of struct ttm_lru_walk and
    struct ttm_bo_lru_cursor.
  drm/ttm, drm/xe: Modify the struct ttm_bo_lru_walk_cursor
    initialization
  drm/ttm, drm_xe, Implement ttm_lru_walk_for_evict() using the guarded
    LRU iteration

[PATCH 1/3] drm/ttm: Use a struct for the common part of struct ttm_lru_walk and struct ttm_bo_lru_cursor.

[Thomas Hellström]

Let the locking functions take the new struct ttm_lru_walk_arg
as argument in order for them to be easily used from both
types of walk.

We could even clean that up further I think, but for now Reviewed-by: Christian König <christian.koenig@amd.com>

[PATCH 2/3] drm/ttm, drm/xe: Modify the struct ttm_bo_lru_walk_cursor initialization

[Thomas Hellström]

Instead of the struct ttm_operation_ctx, Pass a struct ttm_lru_walk_arg
to enable us to easily extend the walk functionality, and to
implement ttm_lru_walk_for_evict() using the guarded LRU iteration.

[PATCH 3/3] drm/ttm, drm_xe, Implement ttm_lru_walk_for_evict() using the guarded LRU iteration

[Thomas Hellström]

To avoid duplicating the tricky bo locking implementation,
Implement ttm_lru_walk_for_evict() using the guarded bo LRU iteration.

To facilitate this, support ticketlocking from the guarded bo LRU
iteration.

That looks mostly identical to a patch I have in my drm_exec branch.

A few questions below.

Giving first as bool parameter here looks really ugly. Isn't there any other way to do this?

Could/should we move needs_unlock into arg as well?

Apart from that looks good to me.

I agree. The previous way of doing this with a bo_from_res() isn't a
good fit since if ticketlocking, we'd like to return without the
spinlock held, and be called with the spinlock held. That's really
confusing both to readers and static analyzers so rather avoided.

We could look at curs->bo and see if it's NULL, but then I think the
bool argument is more readable. But if you have a better idea, I'm of
course open to changing this.

They are different in that arg is state that governs the whole loop but
needs_unlock is local to a single iteration. We could of course pass
the cursor to the various locking functions to eliminate one argument
now that walk_for_evict() also uses the cursor.

Thoughts?

commit 7ca1f80a2063b9ff68502846af167af83e39e516

    drm/ttm, drm_xe, Implement ttm_lru_walk_for_evict() using the guarded LRU iteration
    
    To avoid duplicating the tricky bo locking implementation,
    Implement ttm_lru_walk_for_evict() using the guarded bo LRU iteration.
    
    To facilitate this, support ticketlocking from the guarded bo LRU
    iteration.

 		     (_bo) = ttm_bo_lru_cursor_next(_cursor))

BUT SEE:

   do {} while (0) advice is over-stated in a few situations:

   The more obvious case is macros, like MODULE_PARM_DESC, invoked at
   file-scope, where C disallows code (it must be in functions).  See
   $exceptions if you have one to add by name.

   More troublesome is declarative macros used at top of new scope,
   like DECLARE_PER_CPU.  These might just compile with a do-while-0
   wrapper, but would be incorrect.  Most of these are handled by
   detecting struct,union,etc declaration primitives in $exceptions.

   Theres also macros called inside an if (block), which "return" an
   expression.  These cannot do-while, and need a ({}) wrapper.

   Enjoy this qualification while we work to improve our heuristics.
