* util/slab: re-design to allow migration between pools (v3)Nicolai Hähnle2016-10-052-89/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is basically a re-write of the slab allocator into a design where multiple child pools are linked to a parent pool. The intention is that every (GL, pipe) context has its own child pool, while the corresponding parent pool is held by the winsys or screen, or possibly the GL share group. The fast path is still used when objects are freed by the same child pool that allocated them. However, it is now also possible to free an object in a different pool, as long as they belong to the same parent. Objects also survive the destruction of the (child) pool from which they were allocated. The slow path will return freed objects to the child pool from which they were originally allocated. If that child pool was destroyed, the corresponding page is considered an orphan and will be freed once all objects in it have been freed. This allocation pattern is required for pipe_transfers that correspond to (GL) buffer object mappings when the mapping is created in one context which is later destroyed while other contexts of the same share group live on -- see the bug report referenced below. Note that individual drivers do need to migrate to the new interface in order to benefit and fix the bug. v2: use singly-linked lists everywhere v3: use p_atomic_set for page->u.num_remaining Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97894
* util: use GCC atomic intrinsics with explicit memory modelNicolai Hähnle2016-10-051-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | This is motivated by the fact that p_atomic_read and p_atomic_set may somewhat surprisingly not do the right thing in the old version: while stores and loads are de facto atomic at least on x86, the compiler may apply re-ordering and speculation quite liberally. Basically, the old version uses the "relaxed" memory ordering. The new ordering always uses acquire/release ordering. This is the strongest possible memory ordering that doesn't require additional fence instructions on x86. (And the only stronger ordering is "sequentially consistent", which is usually more than you need anyway.) I would feel more comfortable if p_atomic_set/read in the old implementation were at least using volatile loads and stores, but I don't see a way to get there without typeof (which we cannot use here since the code is compiled with -std=c99). Eventually, we should really just move to something that is based on the atomics in C11 / C++11. Acked-by: Marek Olšák <[email protected]> Reviewed-by: Emil Velikov <[email protected]>

* st/glsl_to_tgsi: reduce stack explosion in recursive expression visitorNicolai Hähnle2016-04-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | In optimized builds, visit(ir_expression *) experiences inlining with gcc that leads the function to have a roughly 32KB stack frame. This is a problem given that the function is called recursively. In non-optimized builds, the stack frame is much smaller, hence one gets crashes that happen only in optimized builds. Arguably there is a compiler bug or at least severe misfeature here. In any case, the easy thing to do for now seems to be moving the bulk of the non-recursive code into a separate function. This is sufficient to convince my version of gcc not to blow up the stack frame of the recursive part. Just to be sure, add the gcc-specific noinline attribute to prevent this bug from reoccuring if inliner heuristics change. v2: put ATTRIBUTE_NOINLINE into macros.h Cc: "11.1 11.2" <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95133 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95026 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92850 Reviewed-by: Ilia Mirkin <[email protected]> Reviewed-by: Rob Clark <[email protected]>
