It has never really been used due to various issues with GDS in the
past and it will be lowered in NIR at some point.
The driver support is still there because it can likely be re-used.
This implementation can also be used as a reference point.

this feature lets zink avoid the screen-based framebuffer cache with locks
in favor of a context-based one that doesn't need any complicated wizardry
to work since it doesn't need to track refcounts for attachments or work
across contexts since the surface info gets passed in when the renderpass
is begun
also expand the dummy surface to an array for use with multisampling and simplify
surface refs there for non-imageless case

This estimation was incorrect, the number of waves doesn't only
depend of the number of VGPRs.
Though, {SPI,COMPUTE}_TMPRING_SIZE.WAVES should limit the number of
scratch waves in flight, not sure if limiting it really works.
This fixes a GPU hang with an upcoming game, and this might also
helps resolving some spurious random GPU hangs.

Offical naming of Mali GPUs is like Mali-G52 or Mali-T860 wth a dash.
Also variants of the same GPU e.g. revision 1 are generally not part
of the name. This adds a dash instead of a space between Mali and the
model and also splits off the r1 revision with a space. This should
keep the naming in-line with offical names and with what the binary
DDK uses for naming.

This is the last step before we can start removing the history flush
mechanism: In cases where a dirtied buffer has the potential to be
concurrently bound to the pipeline (as indicated by the bind_history
mask), flag the "flush" dirty bits corresponding to its binding point.
This ensures that the buffer-local memory barriers introduced earlier
in this series are executed before the next draw call, which in turn
will emit any necessary PIPE_CONTROLs in cases where the buffer is
bound through a cache incoherent with the cache that performed the
write.

This adds buffer-local barriers so any required synchronization
commands are emitted before a buffer object is used as source for
indirect draw parameters. An unconditional PIPE_CONTROL meant to
flush the contents of the draw count buffer can now be removed, since
it's redundant with the more accurate buffer-local barrier introduced
here, which should avoid flushing in cases where the buffer wasn't
written by any incoherent cache since the last flush.

This will allow us to order writes and reads of vertex and index

across the whole driver.

We're moving away from relying on the Kernel's implicit busy tracking
into our own tracking, except for shared buffers.
Not only this shouldn't hurt now (it doesn't, according to my
measurements), when we switch to vm_bind we will be able to cut some
significant overhead by simply omitting all the async buffers from the
execbuf ioctl.

- Change iris_bo_busy() to bool (Ken).
- Fix coding style issues (Ken).

The next patches will justify the new ownership. We want the BOs to
have references on the batches' syncobjs so we can implement implicit
tracking. In other words: BOs will be able to wait on syncobjs owned
by different screens. Since our syncobjs are actually just a Kernel
handle with a refcount, they can be used globally and it makes more
sense to map them to the bufmgr, just like the BOs.
