Stencil buffers have strange pitch. The PRM says:
The pitch must be set to 2x the value computed based on width,
as the stencil buffer is stored with two rows interleaved.
anv_cmd_buffer_clear_attachments() skipped the clear renderpass if no
color attachments needed to be cleared, even if a depth attachment
needed to be cleared.
In anv_depth_stencil_view, replace the members
bo
depth_offset
depth_stride
depth_format
depth_qpitch
stencil_offset
stencil_stride
stencil_qpitch
with the single member
const struct anv_image *image
The removed members duplicated data in anv_image::depth_surface and
anv_image::stencil_surface.
The format of the view itself and of the view's image may differ.
Moreover, if the view's format has no depth aspect but the image's
format does, we must not program the depth buffer. Ditto for stencil.
If the packet encoding is defined in the same format as register definitions,
the python script can process them automatically and the parser support
becomes trivial.

This adds trace points to all IBs and the parser prints them and also
prints which trace points were reached (executed) by the CP.
This can help pinpoint a problematic packet, draw call, etc.

GPU hang detection must be enabled by setting: GALLIUM_DDEBUG=[timeout in ms]
This may print too much information that we might not understand yet,
but some of the bits are very useful.

This makes writing a good IB parser a lot easier.
It generates 2 tables:
- packet3 table
- register table with all registers, fields, and named values

v2: lots of improvements
This is like identity or trace, but simpler. It doesn't wrap most states.
Run with:
GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.
If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
/home/$username/dd_dumps/$processname_$pid_$index.
Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.
You can also do:
GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.
Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.
v2: drop pipe-loader changes, drop SConscript
rename dd.h -> dd_pipe.h

This works if drivers upsample on upload (like all radeon ones do).
The alternative is an unexpected GL error from anything calling
_mesa_update_state and possibly other issues.
