5 years agou_dynarray: turn util_dynarray_{grow, resize} into element-oriented macros

u_dynarray: turn util_dynarray_{grow, resize} into element-oriented macros

The main motivation for this change is API ergonomics: most operations
on dynarrays are really on elements, not on bytes, so it's weird to have
grow and resize as the odd operations out.

The secondary motivation is memory safety. Users of the old byte-oriented
functions would often multiply a number of elements with the element size,
which could overflow, and checking for overflow is tedious.

With this change, we only need to implement the overflow checks once.
The checks are cheap: since eltsize is a compile-time constant and the
functions should be inlined, they only add a single comparison and an
unlikely branch.

v2:
- ensure operations are no-op when allocation fails
- in util_dynarray_clone, call resize_bytes with a compile-time constant element size

v3:
- fix iris, lima, panfrost

u_dynarray: return 0 on realloc failure and ensure no-op

We're not very good at handling out-of-memory conditions in general, but
this change at least gives the caller the option of handling it gracefully
and without memory leaks.

This happens to fix an error in out-of-memory handling in i965, which has
the following code in brw_bufmgr.c:

      node = util_dynarray_grow(vma_list, sizeof(struct vma_bucket_node));
      if (unlikely(!node))
         return 0ull;

Previously, allocation failure for util_dynarray_grow wouldn't actually
return NULL when the dynarray was previously non-empty.

v2:
- make util_dynarray_ensure_cap a no-op on failure, add MUST_CHECK attribute
- simplify the new capacity calculation: aside from avoiding a useless loop
  when newcap is very large, this also avoids an infinite loop when newcap
  is larger than 1 << 31

Alyssa Rosenzweig [Tue, 11 Jun 2019 19:25:35 +0000 (12:25 -0700)]
panfrost: Replace pantrace with direct decoding

History lesson! In the early days of a Panfrost, we had a library
independent of the driver called `panwrap` which would be LD_PRELOAD'ed
into a driver to decode its cmdstream in real-time. When upstreaming
Panfrost, we realized that we would much rather have this decode
functionality maintained in-tree to avoid divergence, but that we could
not upstream panwrap because of its use with the legacy API. So we
instead dumped GPU memory to the filesystem with an out-of-tree panwrap,
and decoded that with the in-tree pandecode module. When we migrated to
the new kernel, we just added support for doing this memory dump
directly from the driver (via a module "pantrace").

This works, but dumping memory every frame is sloooooooooooooow and
error-prone. I figured if we have pandecode in-tree, we might as well
link to it directly in the driver, allowing us to decode Panfrost's
command streams without dumping memory to the filesystem first. This
cleans up the code *substantially* and improves dumping performance by a
HUGE margin. I'm talking "several seconds per frame" to "dumping in
real-time" kind of jump.

Note to users: this removes the environmental option "PANTRACE_BASE".
Instead, for equivalent functionality set "PAN_MESA_DEBUG=trace" and
redirect stdout to the file of your choosing.

This should be debugging Panfrost much more pleasant.

a couple potential sharp edges:

 1) the uncompressed buffer could have different layout, ie. a5xx

 2) if it comes mid-batch, it would force flush, or somehow fixing

    shadowing approach we can rely on batch re-ordering to avoid
