drm: extra printk() wrapper macros

2018-01-17T17:55:24+00:00

[ Upstream commit 30b0da8d556e65ff935a56cd82c05ba0516d3e4a ]

We had only DRM_INFO() and DRM_ERROR(), whereas the underlying printk()
provides several other useful intermediate levels such as NOTICE and
WARNING. So this patch fills out the set by providing both regular and
once-only macros for each of the levels INFO, NOTICE, and WARNING, using
a common underlying macro that does all the token-pasting.

DRM_ERROR is unchanged, as it's not just a printk wrapper.

drm/ttm: Make ttm_bo_mem_compat available

2016-08-03T15:46:07+00:00

[ Upstream commit 94477bff390aa4612d2332c8abafaae0a13d6923 ]

There are cases where it is desired to see if a proposed placement
is compatible with a buffer object before calling ttm_bo_validate().

drm/dp/mst: move GUID storage from mgr, port to only mst branch

2016-04-13T21:14:24+00:00

[ Upstream commit 5e93b8208d3c419b515fb75e2601931c027e12ab ]

Previous implementation does not handle case below: boot up one MST branch
to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output
of 1st MST, GUID is not created for 2nd MST branch. When downstream port of
2nd MST branch send upstream request, it fails because 2nd MST branch GUID
is not available.

New Implementation: only create GUID for MST branch and save it within Branch.

drm/dp/mst: Remove port after removing connector.

2016-02-15T20:45:35+00:00

[ Upstream commit 4772ff03df8094fd99d28de5fcf5df3a3e9c68bb ]

The port is removed synchronously, but the connector delayed.
This causes a use after free which can cause a kernel BUG with
slug_debug=FPZU. This is fixed by freeing the port after the
connector.

This fixes a regression introduced with
6b8eeca65b18ae77e175cc2b6571731f0ee413bf
"drm/dp/mst: close deadlock in connector destruction."

drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil

2016-02-15T20:45:35+00:00

[ Upstream commit 64566b5e767f9bc3161055ca1b443a51afb52aad ]

drm_fixp_from_fraction allows us to create a fixed point directly
from a fraction, rather than creating fixed point values and dividing
later. This avoids overflow of our 64 bit value for large numbers.

drm_fixp2int_ceil allows us to return the ceiling of our fixed point
value.

We should always send reply for UP request in order
to make downstream device clean-up resources appropriately.

Issue was that reply for UP request was sent only once.

commit ae491542cbbbcca0ec8938c37d4079a985e58440 upstream.

This zeroes the msg so no random stack data ends up getting
sent, it also limits the function to not accepting > 4
i2c msgs.
