Hi Andrzej:
Really a good idea for introducing this custom size check, it's very
useful for some Komeda/malidp format, espcially pitch_multiplier, maybe
in future we can add it into into the drm_format_info.

The fbdev emulation is only ever used on Ingenic SoCs to run old SDL1
based games at 16bpp (rgb565). Recent applications generally talk to
DRM directly, and can request their favourite pixel format; so we can
make everybody happy by switching the emulated fbdev to 16bpp.

Hi James,
Thank you for the review.
Did you intentionally review patches from the v4 series or you simply
didn't notice the v5? There are some differences, the most notable one
is using proper way of subclassing a drm_framebuffer.
The v5 series was sent on 17th December 2019.

Well, gpu_offset is still in struct qxlslot ...
Other than that the patch looks fine, and this is minor enough

Hi everyone,
hopefully the last iteration of those patches.
For now I've addressed the issue of unmapping imported BOs from the amdgpu page
tables immediately by locking the page tables in place.
For HMM handling we are getting the ability to invalidate BOs without locking
the VM anyway, so th
On the exporter side we add optional explicit pinning callbacks. Which are
called when the importer doesn't implement dynamic handling, move notification
or need the DMA-buf locked in place for its use case.
On the importer side we add an optional move_notify callback. This callback is
used by the
Implement the importer side of unpinned DMA-buf handling.

Avoid that we ping/pong the buffers when we stop to pin DMA-buf
exports by using the allowed domains for exported buffers.

Please ignore this one, I've send out the wrong version without Daniels
latest comment nit picks fixed.
The interesting one in this series is the last patch.
