Eric Anholt dffa9b7a78 drm/v3d: Add missing implicit synchronization.
It is the expectation of existing userspace (X11 + Mesa, in
particular) that jobs submitted to the kernel against a shared BO will
get implicitly synchronized by their submission order.  If we want to
allow clever userspace to disable implicit synchronization, we should
do that under its own submit flag (as amdgpu and lima do).

Note that we currently only implicitly sync for the rendering pass,
not binning -- if you texture-from-pixmap in the binning vertex shader
(vertex coordinate generation), you'll miss out on synchronization.

Fixes flickering when multiple clients are running in parallel,
particularly GL apps and compositors.

v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

Eric Anholt d223f98f02 drm/v3d: Add support for compute shader dispatch.
The compute shader dispatch interface is pretty simple -- just pass in
the regs that userspace has passed us, with no CLs to run.  However,
with no CL to run it means that we need to do manual cache flushing of
the L2 after the HW execution completes (for SSBO, atomic, and
image_load_store writes that are the output of compute shaders).

This doesn't yet expose the L2 cache's ability to have a region of the
address space not write back to memory (which could be used for
shared_var storage).

So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
the ES31 tests), and on the kernel side on 7278 (failing atomic
compswap tests in a way that doesn't reproduce on simpenrose).

v2: Fix excessive allocation for the clean_job (reported by Dan
    Carpenter).  Keep refs on jobs until clean_job is finished, to
    avoid spurious MMU errors if the output BOs are freed by userspace
    before L2 cleaning is finished.

Eric Anholt a783a09ee7 drm/v3d: Refactor job management.
The CL submission had two jobs embedded in an exec struct.  When I
added TFU support, I had to replicate some of the exec stuff and some
of the job stuff.  As I went to add CSD, it became clear that actually
what was in exec should just be in the two CL jobs, and it would let
us share a lot more code between the 4 queues.

v2: Fix missing error path in TFU ioctl's bo[] allocation.

drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM operations
Our driver makes a typical use of CMA, with GEM object allocated as
GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops
instead of duplicating them.

Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op
which sets per-object funcs (drm_cma_gem_default_funcs), we can also
get rid of free_object_unlocked and gem_vm_ops, which are superseded
by the object funcs.

Steven Price db594ba3fc drm/panfrost: depend on !GENERIC_ATOMIC64 when using COMPILE_TEST
Since panfrost has a 'select' on IOMMU_IO_PGTABLE_LPAE we must depend on
the same set of flags. Otherwise IOMMU_IO_PGTABLE_LPAE will be forced on
even though it cannot build (no support for cmpxchg64).

This fixes the following warning from kconfig:

Vicente Bergas b8f9d7f37b drm/rockchip: shutdown drm subsystem on shutdown
As explained by Robin Murphy:
> the IOMMU shutdown disables paging, so if the VOP is still
> scanning out then that will result in whatever IOVAs it was using now going
> straight out onto the bus as physical addresses.

We had a more radical approach before in commit
7f3ef5dedb ("drm/rockchip: Allow driver to be shutdown on reboot/kexec")
but that resulted in new warnings and oopses on shutdown on rk3399
chromeos devices.

So second try is resurrecting Vicentes shutdown change which should
achieve the same result but in a less drastic way.

Instead of checking the upper values of the sequence number use an explicit
field in the dma_fence_ops structure to note if a sequence should be 32bit

Rob Herring 4dff47c760 drm/panfrost: Add support for 2MB page entries
Add support for 2MB sized pages. This will improve our map and unmap
times and save a bit of memory by avoiding 3rd level page tables for
contiguous allocations.

As we use shmem for buffers and huge page allocations for shmem are off
by default, there isn't an improvement out of the box and userspace must
enable THP for shmem.

It's not clear if the h/w can support 1GB page sizes which standard
ARM long format descriptors support. In any case, it is unlikely we'll
see any contiguous 1GB allocations on current h/w.

Rob Herring d08d42de64 iommu: io-pgtable: Add ARM Mali midgard MMU page table format
ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but
have a few differences. Add a new format type to represent the format. The
input address size is 48-bits and the output address size is 40-bits (and
possibly less?). Note that the later bifrost GPUs follow the standard
64-bit stage 1 format.

The differences in the format compared to 64-bit stage 1 format are:

The 3rd level page entry bits are 0x1 instead of 0x3 for page entries.

The access flags are not read-only and unprivileged, but read and write.
This is similar to stage 2 entries, but the memory attributes field matches
stage 1 being an index.

The nG bit is not set by the vendor driver. This one didn't seem to matter,
but we'll keep it aligned to the vendor driver.
