radv: force cs/ps/l2 flush at end of command stream. (v2)

This seems like a workaround, but we don't see the bug on CIK/VI.

On SI with the dEQP-VK.memory.pipeline_barrier.host_read_transfer_dst.*
tests, when one tests complete, the first flush at the start of the next
test causes a VM fault as we've destroyed the VM, but we end up flushing
the compute shader then, and it must still be in the process of doing
something.

Could also be a kernel difference between SI and CIK.

v2: hit this with a bigger hammer. This fixes a bunch of hangs
in the vk cts with the robustness tests.

i965/miptree: Call alloc_aux in create_for_bo

Originally, I had moved it to the caller to make some things easier when
adding the CCS modifier.  However, this broke DRI2 because
intel_process_dri2_buffer calls intel_miptree_create_for_bo but never

6 years agointel/isl: Stop padding surfaces
Jason Ekstrand [Mon, 31 Jul 2017 15:33:22 +0000 (08:33 -0700)]
intel/isl: Stop padding surfaces

The docs contain a bunch of commentary about the need to pad various
surfaces out to multiples of something or other.  However, all of those
requirements are about avoiding GTT errors due to missing pages when the
data port or sampler accesses slightly out-of-bounds.  However, because
the kernel already fills all the empty space in our GTT with the scratch
page, we never have to worry about faulting due to OOB reads.  There are
two caveats to this:

 1) There is some potential for issues with caches here if extra data
    ends up in a cache we don't expect due to OOB reads.  However,
    because we always trash the entire cache whenever we need to move
    anything between cache domains, this shouldn't be an issue.

 2) There is a potential issue if a surface gets placed at the very top
    of the GTT by the kernel.  In this case, the hardware could
    potentially end up trying to read past the top of the GTT.  If it
    nicely wraps around at the 48-bit (or 32-bit) boundary, then this
    shouldn't be an issue thanks to the scratch page.  If it doesn't,
    then we need to come up with something to handle it.

Up until some of the GL move to ISL, having the padding code in there
just caused us to harmlessly use a bit more memory in Vulkan.  However,
now that we're using ISL sizes to validate external dma-buf images,
these padding requirements are causing us to reject otherwise valid
images due to the size of the BO being too small.

loader: rework xmlconfig dependency

Currently xmlconfig is conditionally used, only when --enable-dri is
available.

As the library has moved to src/util and has wider wisebase, this guard
is no longer correct. Strictly speaking - it wasn't since the
introduction of xmlconfig into st/nine a while ago.

Unconditionally enable xmlconfig and drop the linking. As said before
there's other users of the library, so depending on the configure
options we will get multiple definitions of said symbols.

NOTE: To avoid breaking other combinations, this commit adds the
xmlconfig link to the required places - throughout gallium and the DRI
loaders.

6 years agoi965: Reduce passing 2x32b of reloc_domains to 2 bits
Chris Wilson [Fri, 21 Jul 2017 15:36:52 +0000 (16:36 +0100)]
i965: Reduce passing 2x32b of reloc_domains to 2 bits

The kernel only cares about whether the object is to be written to or
not, only reduces (reloc.read_domains, reloc.write_domain) down to just
!!reloc.write_domain. When we use NO_RELOC, the kernel doesn't even read
those relocs and instead userspace has to pass that information in the
execobject.flags. We can simplify our reloc api by also removing the
unused read/write domains and only pass the resultant flags.

The caveat to the above are when we need to make the kernel aware that
certain objects need to take into account different work arounds.
Previously, this was done using the magic (INSTRUCTION, INSTRUCTION)
reloc domains. NO_RELOC requires this to be passed in the execobject
flags as well, and now we push that up the callstack.

The API is more compact, more expressive of what happens underneath, but
unfortunately requires more knowledge of the system at the point of use.
Conversely it also means that knowledge is specific and not generally
applied and so not overused.

i965: Convert reloc.target_handle into an index for I915_EXEC_HANDLE_LUT

Based on a patch by Chris Wilson (who also wrote this commit message).

Passing the index of the target buffer via the reloc.target_handle is
marginally more efficient for the kernel (it can avoid some allocations,
and can use a direct lookup rather than a hash or search). It is also
useful for ourselves as we can use the index into our exec_bos for other
tasks.

v2: Only enable HANDLE_LUT if we can use BATCH_FIRST and thereby avoid
a post-processing loop to fixup the relocations.
v3: Move kernel probing from context creation to screen init.
