drm/vmwgfx: Make sure we unpin no longer needed buffers · d1a73c64

Zack Rusin authored Jan 14, 2021

We were not correctly unpinning no longer needed buffers. In particular
vmw_buffer_object, which is internally often pinned on creation wasn't
unpinned on destruction and none of the internal MOB buffers were
unpinned before being put back. Technically this existed for a
long time but commit 57fcd550 ("drm/ttm: Warn on pinning without
holding a reference") introduced a WARN_ON which was filling up the
kernel logs rather quickly.

Quite frankly internal usage of vmw_buffer_object and in general
pinning needs to be refactored in vmwgfx but for now this makes
it work.

dt-bindings: dp-connector: Drop maxItems from -supply · ca230ab1

Bjorn Andersson authored Jan 20, 2021

The meta-schema recently gained a definition for the common -supply$
property, which denotes that maxItems is not a valid property. Drop this
to clear up the binding validation error.

drm: Added orientation quirk for OneGX1 Pro · 81ad7f9f

Jared Baldridge authored Jan 20, 2021

The OneGX1 Pro has a fairly unique combination of generic strings,
but we additionally match on the BIOS date just to be safe.

drm/syncobj: make lockdep complain on WAIT_FOR_SUBMIT v3 · 7621350c

Christian König authored Jan 15, 2021

DRM_SYNCOBJ_WAIT_FLAGS_WAIT_FOR_SUBMIT can't be used when we hold locks
since we are basically waiting for userspace to do something.

Holding a lock while doing so can trivial deadlock with page faults
etc...

So make lockdep complain when a driver tries to do this.

v2: Add lockdep_assert_none_held() macro.
v3: Add might_sleep() and also use lockdep_assert_none_held() in the
    IOCTL path.

drm/ttm: add debugfs directory v2 · 3763d635

Christian König authored Nov 17, 2020

As far as I can tell the buffer_count was never used by an
userspace application.

The number of BOs in the system is far better suited in
debugfs than sysfs and we now should be able to add other
information here as well.

v2: add that additionally to sysfs

video: fbdev: simplefb: Fix info message during probe · 5269a618

Peter Robinson authored Dec 28, 2020

The info message was showing the mapped address for the framebuffer. To avoid
security problems, all virtual addresses are converted to __ptrval__, so
the message has pointless information:

simple-framebuffer 3ea9b000.framebuffer: framebuffer at 0x3ea9b000, 0x12c000 bytes, mapped to 0x(____ptrval____)

Drop the extraneous bits to clean up the message:

simple-framebuffer 3ea9b000.framebuffer: framebuffer at 0x3ea9b000, 0x12c000 bytes
