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.

Previously, allocation failure for util_dynarray_grow wouldn't actually

v2:

- simplify the new capacity calculation: aside from avoiding a useless loop

5 years agopanfrost: Replace pantrace with direct decoding
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.

freedreno/a6xx: disable UBWC for some formats

An older blob claims to support UBWC w/ r32ui an r32i, but not r32f.
Results from deqp indicate that it doesn't work with r32ui and r32i.

This *could* also just mean that use as "IBO" (image) is more limited
than as texture, although blob also doesn't seem to bother to try to use
UBWC with images at all, so hard to know for sure.

5 years agofreedreno: add helper to uncompress UBWC resource
Rob Clark [Fri, 7 Jun 2019 17:14:12 +0000 (10:14 -0700)]
freedreno: add helper to uncompress UBWC resource

We'll need this for a few edge cases, like image/sampler view that uses
a format that UBWC does not support with a resource originally created
in a format that UBWC does support.

NOTE we *could* in some cases do an in-place uncompress.  But that has
a couple potential sharp edges:

 1) the uncompressed buffer could have different layout, ie. a5xx
    with meta and pixel data of layers/levels interleaved.

 2) if it comes mid-batch, it would force flush, or somehow fixing
    up cmdstream for draws already emitted.  But with the resource
    shadowing approach we can rely on batch re-ordering to avoid
    splitting things.. older draws see the older compressed version,
    newer draws see the new uncompressed version of the rsc.
