Hi Dave, Daniel,
A few fixes for 5.8. It would be nice to get these in for 5.8 final, but if
it's too late, they can go back via stable from 5.9.
The following changes since commit a4a2739beb8933a19281bca077fdb852598803ed:
Merge tag 'drm-misc-fixes-2020-07-28' of
git://anongit.freedesktop.or
Use switch - case to downshift from the current link rate. It's a small
loop now, so fine to be replaced with switch - case. With a loop, it is
confusing and hard to follow as reported below.
The patch d76271d22694: "drm: xlnx: DRM/KMS driver for Xilinx ZynqMP
DisplayPort Subsystem" from Jul 7, 20
Hi Daniel,
Thanks for the review.

Again, we don't have any need to suspend the device synchronously here,
and doing so could in theory lead to a deadlock (although it's unlikely
since we've called pm_runtime_mark_last_busy() before-hand).

While I don't know of any problems this has caused, it's definitely not

Looks like that we forgot to handle -EINPROGRESS being returned by
pm_runtime_get(), which can happen if multiple callers try to
asynchronously resume the GPU before it wakes up. This is perfectly
normal and OK, so fix this by treating -EINPROGRESS as success.

fbcon events will get handled anyway)
So, let's fix those.

The loop should exit at the lowest link rate, so break the loop
at the lowest link rate without check. The check is always true
because lowest link rate is smaller than current one and maximum
of current display. Otherwise, it may be seen as the loop can
potentially result in negative array offset.

Enabling a whole subsystem from a single driver 'select' is frowned
upon and won't be accepted in new drivers, that need to use 'depends on'
instead. Existing selection of DMAENGINES will then cause circular

At least sparc64 requires I/O-specific access to framebuffers. This
patch prepares the fbdev console accordingly.
For drivers with direct access to the framebuffer memory, the callback
functions test for the type of memory and call the rsp fb_sys_ of fb_cfb_
functions. For drivers that employ a sh

DRM's fbdev console uses regular load and store operations to update
framebuffer memory. The bochs driver on sparc64 requires the use of
I/O-specific load and store operations. We have a workaround, but need

The vmap_iomem function in struct drm_gem_object_funcs returns the
memory of the buffer if located in I/O memory, or NULL if it isn't.
The patch also updates the semantics of the vmap function to return
NULL if the buffer is not in system memory.

Drop the WARN_ON and consolidate the two paths into one.
