r600/eg: rework atomic counter emission with flushes

With the current code, we didn't do the space checks prior
to atomic counter setup emission, but we also didn't add
atomic counters to the space check so we could get a flush
later as well.

These flushes would be bad, and lead to problems with
parallel tests. We have to ensure the atomic counter copy in,
draw emits and counter copy out are kept in the same command
submission unit.

This reworks the code to drop some useless masks, make the

handle atomic counter space.

radv: do not use CP predication for DCC decompressions

This fixes a regression with some Unity demos. Not sure
what the root cause of the problem is, especially because
the driver doesn't perform any fast color clears. So, it
shouldn't be needed to decompress DCC. RadeonSI says that
the decompression is relatively cheap if the surface has
been decompressed already.

One possible improvement is to two use predicates, one for
DCC and one for FCE that could be cleared when DCC, FMASK
or CMASK are performed by the driver. That might skip some
unnecessary decompression passes (not DCC though).

However the logic was flawed because it never tried to unroll any

If this innermost loop is not unrolled we end up skipping all

gallium/winsys/kms: don't unmap what wasn't mapped

At the moment, depending on pipe transfer flags, the dumb
buffer map address can end up at either kms_sw_dt->ro_mapped
or kms_sw_dt->mapped.

When it's time to unmap the dumb buffer, both locations get unmapped,
even though one is probably initialized to 0.

That leads to the code segment getting unmapped at runtime and
crashes when trying to call into unrelated code.

This commit addresses the problem by using MAP_FAILED instead of
NULL for ro_mapped and mapped when the dumb buffer is unmapped,
and only unmapping mapped addresses at unmap time.

anv/pipeline: Set tess IO read/written key fields in compile_*

We want these to be set as close to the final compile as possible so

called.  The next commit is going to move nir_shader_gather_info to

anv/apply_pipeline_layout: Add to the bind map instead of replacing it

This commit makes three changes.  One is to only walk the descriptors once
and set bind map sizes at the same time as filling out the entries.  The
second is to make the pass additive so that we can put stuff in the bind
map before applying the pipeline layout.  Third, we switch to using
designated initializers.

Because lower_ycbcr gets called before apply_pipeline_layout, the

big for the bounds check.  We should just use the regular logical array

python: Open the template as text, with an explicit encoding

In commit bd27203f4d808763ac24ac94eb677cacf3e7cb99 we changed this to
open in binary mode, to then explicitly decode the lines with the right
encoding.

Unfortunately, that broke the build on Windows, where the template file
can have '\r\n' as line terminators: opening in binary mode would keep
those terminators and break the regexp.

We need to go back to text mode, where the "universal newlines" mode
takes care of this.

However, to fix the initial issue, let's specify the encoding explicitly
when opening the file, and make sure it is open in text mode, so we only
get unicode strings.
