Maybe atomic userspace is better (it should be, it can do TEST_ONLY),
but I'm not so sure that exposing all modes for atomic clients would
work. Also, currently not possible with our...

Well, I can reintroduce the module option. I don't see any other
reasonable way to support 32bpp. If the driver reports XR24 as
supported and also adds the higher resolutions (which work with RG16
only) to the mode list userspace will of course try the higher
resolutions with XR24 and struggle ...

[PATCH v3 5/5] drm/cirrus: rewrite and modernize driver.
...ideo 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.

[PATCH 00/17] cirrus: Modernize the cirrus driver
Update the cirrus driver to follow current best practices. While the
driver's hardware is obsolete, the cirrus driver is still one of the
go-to modules to learn about writing a DRM driver. So keep it in good
shape.
Patches 1 to 3 simplify blitting and convert it to the DRM's current
helpers.
Patches 4 to 8 replace simple-KMS helpers with DRM's regular atomic
helpers. The former are

[PATCH] drm/cirrus: rewrite and modernize driver.
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
