Vulkan has introduced the consept of .specVersion which can be used to
attribute changes of the said extension.
The current loader does not check the value, thus it have gone unnoticed
that the driver exposes an old version of the following extensions:
VK_KHR_xcb_surface (Rev 6)
VK_KHR_xlib_surface (Rev 6)
VK_KHR_wayland_surface (Rev 5)
- Updated the surface create function to take a pCreateInfo structure
VK_KHR_swapchain (Rev 68)
- Moved the "validity" include for vkAcquireNextImage to be in its proper
place, after the prototype and list of parameters.
...
According to the documentation:
* pname:specVersion is the version of this extension.
It is an integer, incremented with backward compatible changes.
Based on the history of vk.xml the above (latest) revision has been
available since Vulkan 1.0 so even if they were any backwards
incompatible change(s) [as hinted by the revision log] those should be
safe.

Since our surface state buffer is shared by all batches, the kernel does a
full stall and sync with the CPU between batches every time we call
execbuf2 because it refuses to do relocations on an active buffer. Doing
them in userspace and passing the NO_RELOC flag to the kernel allows us to
perform the relocations without stalling.
This improves the performance of Dota 2 by around 30% on a Sky Lake GT2.

Ever since the early days of the Vulkan driver, we've been setting up the
lists of relocations at EndCommandBuffer time. The idea behind this was to
move some of the CPU load out of QueueSubmit which the client is required
to lock around and into command buffer building which could be done in
parallel. Then QueueSubmit basically just becomes a bunch of execbuf2
calls.
Technically, this works. However, when you start to do more in QueueSubmit
than just execbuf2, you start to run into problems. In particular, if a
block pool is resized between EndCommandBuffer and QueueSubmit, the list of
anv_bo's and the execbuf2 object list can get out of sync. This can cause
problems if, for instance, you wanted to do relocations in userspace.

The original reason for putting it in the batch_bo was to allow primaries
to share it across secondaries or something like that. However, the
relocation lists in secondary command buffers are are always left alone and
copied into the primary command buffer's relocation list. This means that
the offset really applies at the command buffer level and putting it in the
batch_bo doesn't make sense. This fixes a couple of potential bugs around
re-submission of command buffers that are not likely to be hit but are bugs
none the less.

This commit adds a little helper struct for storing everything we use to
build an execbuf2 call. Since the add_bo function really has nothing to do
with a command buffer, it makes sense to break it out a bit. This also

Since -1 is an invalid GPU address, this lets us know whether or not we

The previous implementation was being overly clever and using the
anv_bo::size field as its mutex. Scratch pool allocations don't happen
often, will happen at most a fixed number of times, and never happen in the
critical path (they only happen in shader compilation). We can make this
much simpler by just using the device mutex. This also means that we can
start using anv_bo_init_new directly on the bo and avoid setting fields
one-at-a-time.

Because our relocation processing happens at EndCommandBuffer time and
because RENDER_SURFACE_STATE objects may be shared by batches, we really
have no clue whatsoever what address is actually written to the relocation
offset in the BO. We need to stop making such claims to the kernel and
just let it relocate for us.

Here brw_setup_vue_interpolation() is rewritten not to use the InterpQualifier
array in gl_fragment_program which will allow us to remove it.
This change also makes the code which is only used by gen4/5 more self contained
as it now has its own gen5_fragment_program struct rather than storing the map
in brw_context. This means the interpolation map will only get processed once
and will get stored in the in memory cache rather than being processed everytime
the fs changes.
Also by calling this from the fs compile code rather than from the upload code
and using the interpolation assigned there we can get rid of the
BRW_NEW_INTERPOLATION_MAP flag.
It might not seem ideal to add a gen5_fragment_program struct however by the end
of this series we will have gotten rid of all the brw_{shader_stage}_program
structs and replaced them with a generic brw_program struct so there will only
be two program structs which is better than what we have now.
V2: Don't remove BRW_NEW_INTERPOLATION_MAP from dirty_bit_map until the following
patch to fix build error.
V3 - Suggestions by Jason:
- name struct gen4_fragment_program rather than gen5_fragment_program
- don't use enum with memset()
- create interp mode set helper and simplify logic to call it
- add assert when calling function to show prog will never be NULL for
gen4/5 i.e. no Vulkan

Vulkan has a multi-arch problem... The idea behind the Vulkan loader is
that you have a little json file on your disk that tells the loader where
to find drivers. The loader looks for these json files in standard
locations, and then goes and loads the my_driver.so's that they specify.
This allows you as a driver implementer to put their driver wherever on the
disk they want so long as the ICD points in the right place.
For a multi-arch system, however, you may have multiple libvulkan_intel.so
files installed that the loader needs to pick depending on architecture.
Since the ICD file format does not specify any architecture information,
you can't tell the loader where to find the 32-bit version vs. the 64-bit
version. The way that packagers have been dealing with this is to place
libvulkan_intel.so in the top level lib directory and provide just a name
(and no path) to the loader. It will then use the regular system search
paths and find the correct driver. While this solution works fine for
distro-installed Vulkan drivers, it doesn't work so well for user-installed
drivers because they may put it in /opt or $HOME/.local or some other more
exotic location. In this case, you can't use an ICD json file with just a
library name because it doesn't know where to find it; you also have to add
that to your library lookup path via LD_LIBRARY_PATH or similar.
This patch handles both use-cases by taking advantage of the fact that the
loader dlopen()s each of the drivers and, if one dlopen() calls fails, it
silently continues on to open other drivers. By suffixing the icd file, we
can provide two different json files: intel_icd.x86_64.json and
intel_icd.i686.json with different paths. Since dlopen() will only succeed
on the libvulkan_intel.so of the right arch, the loader will happily ignore
the others and load that one. This allows us to properly handle multi-arch
while still providing a full path so user installs will work fine.
I tested this on my Fedora 25 machine with 32 and 64-bit builds of our
Vulkan driver installed and 32 and 64-bit builds of crucible. It seems to
work just fine.
