19 months agoutil/sparse_array: Stash the node level in the node pointer

util/sparse_array: Stash the node level in the node pointer

This reworks the data structure a bit and, in my view, simplifies it.
Instead of each node having a header which has the node level in it, we
use the bottom 6 bits of the pointer for that.  This requires us to
allocate with the os_malloc/free_aligned helpers (which call into
posix_memalign on Linux) but cache-line aligning our allocations is
actually probably a good thing given that we're doing atomics on them.

The primary advantages to doing this is that it changes the number of
memory accesses per tree level from 2 to 1 when walking the tree because
we no longer have to look at node->level.

19 months agointel/iris: Always initialize CCS to 0
Jason Ekstrand [Wed, 4 Mar 2020 20:37:03 +0000 (14:37 -0600)]
intel/iris: Always initialize CCS to 0

Previously, we were initializing the CCS to 0xFF for MCS+CCS due to a
misunderstanding of the following lines in the bspec:

    The following are the general SW requirements for MCS buffer clear
    functionality:
        ...
         - If Software wants to enable Color Compression without Fast
           clear, Software needs to initialize MCS with zeros.
         - Lossless compression and CCS initialized to all F (using HW
           Fast Clear or SW direct Clear) on the same surface is not
           supported.

The first line does not refer to the CCS as the comment author supposed
but refers to the MCS as the comment says.  It means that if you want to
use MCS compression without a fast-clear, you should initialize the MCS
to 0x00.  This is because the value 0x00 in the MCS means "all data is
in plane 0" which is a perfectly valid non-fast-clear initialization.
It's also the value the MCS should be in if you do a RECTLIST slow-clear
where the primitive fully covers each pixel such that the same value is
written to all samples.

The second line in the above quote seems to imply that CCS fast-clear is
incompatible with MCS fast-clear.  In particular, MCS+CCS fast-clear
uses a 0xff value in the MCS (like on Gen7-11) and leaves the CCS in
either the compressed or the pass-through state.  Therefore, we should
initialize the CCS to 0x00 even for MCS+CCS surfaces.

19 months agosoft-fp64: Split a block that was missing a cast on a comparison

soft-fp64: Split a block that was missing a cast on a comparison

         ((zExp == 0x7FD) &&

      if (zExp < 0) {

I saw that, and I thought, "Uh... what?  Dead code?"  I thought it was a
bit fishy, so I grabbed the Berkeley SoftFloat Library 3e code, and
there is similar code in softfloat_roundPackToF64
(source/s_roundPackToF64.c), but it has an extra (uint16_t) cast in the
first comparison.  This is basicially a shortcut for

   if (zExp < 0 || zExp >= 0x7FD) {

So, having the nesting kind of makes sense. On a CPU, nesting the flow
control can be an optimization.  On a GPU, it's just fail.  Split the
block so that we don't need the uint16_t cast magic.

19 months agosoft-fp64/fsat: Correctly handle NaN
Ian Romanick [Tue, 3 Mar 2020 02:38:11 +0000 (18:38 -0800)]
soft-fp64/fsat: Correctly handle NaN

fsat is defined as min(max(a, 0.0), 1.0), and IEEE defines both min and
max to return the non-NaN value when one value is NaN.  Based on this,
fsat should definitely return 0.0 for NaN.
