5 years agonir, glsl: move pixel_center_integer/origin_upper_left to shader_info.fs

nir, glsl: move pixel_center_integer/origin_upper_left to shader_info.fs

On GLSL that info is set as a layout qualifier when redeclaring
gl_FragCoord, so somehow tied to a specific variable. But in practice,
they behave as a global of the shader. On ARB programs they are set
using a global OPTION (defined at ARB_fragment_coord_conventions), and
on SPIR-V using ExecutionModes, that are also not tied specifically to
the builtin.

This patch moves that info from nir variable and ir variable to nir
shader and gl_program shader_info respectively, so the map is more
similar to SPIR-V, and ARB programs, instead of more similar to GLSL.

FWIW, shader_info.fs already had pixel_center_integer, so this change
also removes some redundancy. Also, as struct gl_program also includes
a shader_info, we removed gl_program::OriginUpperLeft and
PixelCenterInteger, as it would be superfluous.

This change was needed because recently spirv_to_nir changed the order
in which execution modes and variables are handled, so the variables
didn't get the correct values. Now the info is set on the shader
itself, and we don't need to go back to the builtin variable to set
it.

panfrost: Add pandecode (command stream debugger)

The `panwrap` utility can be LD_PRELOAD'd into a GLES app, intercepting
communication between the driver and the kernel. Modern panwrap versions
do no processing of their own; instead, they create a trace directory.
This directory contains the following files:

 - control.log: a line-by-line plain text file, denoting important
   syscalls (mmaps and job submits) along with their arguments

 - memory_*.bin, shader_*.bin: binary dumps of mapped memory

Together, these files contain enough information to reconstruct the
command stream and shaders of (at minimum) a single frame.

The `pandecode` utility takes this directory structure as input,
reconstructing the mapped memory and using the job submit command as an
entrypoint. It then walks the descriptors as the hardware would, parsing
and pretty-printing. Its final output is the pretty-printed command
stream interleaved with the disassembled shaders, suitable for driver
debugging. For instance, the behaviour of two driver versions (one
working, one broken) can be compared by diff'ing their decoded logs.

pandecode/decode.c was originally a part of `panwrap`; it is the oldest
living code in the project. Its history is generally not worth
preserving.

panwrap itself will continue to live downstream for the foreseeable
future, as it is specifically written for the vendor kernel. It is
possible, however, to produce equivalent traces directly from Panfrost,
bypassing the intermediate wrapping layer for well-behaved drivers.

is also reproducible with epiphany.

resized dimensions won't get neither immediately applied on the resize
callback, nor correctly synchronized on update_buffers(), as the
(now stale) surface size and currently attached buffer size still do match.

There's actually 2 things to synchronize here, first the surface query
size might not be updated yet to the wl_egl_window's (i.e. resize_callback
happened while there is a back buffer), and second the wayland buffers
would need dropping if new surface size differs with the currently attached
buffer. These are done in separate steps now.

expands to <V_LOG_F32_e32, V_EXP_F32_e32, V_MUL_LEGACY_F32_e32>,

Lowering in NIR results in a non-legacy multiply, where:

Kenneth Graunke [Wed, 16 Jan 2019 06:35:02 +0000 (22:35 -0800)]
mesa: Align doubles to a 64-bit starting boundary, even if packing.

In the new Intel Iris driver, I am using Tim's new packed uniform
storage system.  It works great, with one caveat: our scalar compiler
backend assumes that uniform offsets will be aligned to the underlying
data type.  For example, doubles must be 64-bit aligned, floats 32-bit,
half-floats 16-bit, and so on.  It does not need any other padding.

Currently, _mesa_add_parameter aligns everything to 32-bit offsets,
creating doubles that have an unaligned offset.  This patch alters
that code to align doubles to 64-bit offsets.

This may be slightly less optimal for drivers which can support full
packing, and allow reads from unaligned offsets at no penalty.  We could
make this extra alignment optional.  However, it only comes into play
when intermixing double and single precision uniforms.  Doubles are
already not too common, and intermixed values (floats then doubles)
is probably even less common.  At most, we burn a single 32-bit slot
to the alignment, which is not that expensive.  So, it doesn't seem
worthwhile to add the extra complexity.

Eventually, we'll likely want to update this code to allow half-float
values to be packed tighter than 32-bit offsets.  At that point, we'll
probably want to revisit what drivers ultimately want, and add options.

gitlab-ci: automatically run the CI on pushes to `ci/*` branches

Last commit limited the CI to master and MRs, but to avoid having to
manually trigger CI runs, let's add a 3rd, automatic way: by pushing to
a branch named `ci/*` (or `ci-*` or just `ci`) (which you can delete
afterwards, the pipeline results will remain).

different behavior depending on whether the def being folded into was a
