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.

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get rid of free_object_unlocked and gem_vm_ops, which are superseded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.

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:

We had a more radical approach before in commit

but that resulted in new warnings and oopses on shutdown on rk3399

So second try is resurrecting Vicentes shutdown change which should

As we use shmem for buffers and huge page allocations for shmem are off

Apart that, it handls ecorrectly all the other HDMI frequencies

frequency with a /2 OD when the 297MHz pixel clock is requested.
This solves the issue on G12A and also works fine on GXBB, GXL & GXM.

Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by roughly 70% I think it'll still be alot easier to review than a
longish baby-step patch series.
Changes summary:
- Given the small amout of video memory (4 MB) the cirrus device has
the rewritten driver doesn't try to manage buffers there. Instead
it will blit (memcpy) the active framebuffer to video memory.
- All gem objects are stored in main memory and are manged using the
new shmem helpers. ttm is out.
- It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24
or RG16 at blit time if needed, to avoid the pitch becoming larger
than what the cirrus hardware can handle.
- The simple display pipeline is used.
- The generic fbdev emulation is used.
- It's a atomic driver now.
- It runs wayland.

It is a drm_fb_xrgb8888_to_rgb565() variant which checks the clip
rectangle for the destination too.
Common code between drm_fb_xrgb8888_to_rgb565() and
drm_fb_xrgb8888_to_rgb565_dstclip() was factored out into the
drm_fb_xrgb8888_to_rgb565_lines() helper function.
