commit 8d83bc22b259e5526625b6d298f637786c71129f upstream.
The VBT provides the platform a way to mix and match the DDI ports vs.
GMBUS pins. Currently we only trust the VBT for DDI E, which I suppose
has no standard GMBUS pin assignment. However, there are machines out
there that use a non-standard mapping for the other ports as well.
Let's start trusting the VBT on this one for all ports on DDI platforms.
I've structured the code such that other platforms could easily start
using this as well, by simply filling in the ddi_port_info. IIRC there
may be CHV system that might actually need this.
v2: Include a commit message, include a debug message during init

commit ff0bd441bdfbfa09d05fdba9829a0401a46635c1 upstream.
Switch the order of the loops to walk the rates on the top
so we exhaust all DP 1.1 rate/lane combinations before trying
DP 1.2 rate/lane combos.
This avoids selecting rates that are supported by the monitor,
but not the connector leading to valid modes getting rejected.

commit 55c4b906aa2aec3fa66310ec03c6842e34a04b2a upstream.
gcc-6 warns about a pointless loop in exynos_drm_subdrv_open:
drivers/gpu/drm/exynos/exynos_drm_core.c: In function 'exynos_drm_subdrv_open':
drivers/gpu/drm/exynos/exynos_drm_core.c:104:199: error: self-comparison always evaluates to false [-Werror=tautological-compare]
list_for_each_entry_reverse(subdrv, &subdrv->list, list) {
Here, the list_for_each_entry_reverse immediately terminates because
the subdrv pointer is compared to itself as the loop end condition.
If we were to take the current subdrv pointer as the start of the
list (as we would do if list_for_each_entry_reverse() was not a macro),
we would iterate backwards over the &exynos_drm_subdrv_list anchor,
which would be even worse.
Instead, we need to use list_for_each_entry_continue_reverse()
to go back over each subdrv that was successfully opened until
the first entry.

commit 537b4b462caa8bfb9726d9695b8e56e2d5e6b41e upstream.
The read is taking a considerable amount of time (about 50us on this
machine). The register does not ever hold anything other than the ring
ID that is updated in this exact function, so there is no need for
the read modify write cycle.
This chops off a big chunk of the time spent in hardirq disabled
context, as this function is called multiple times in the interrupt
handler. With this change applied radeon won't show up in the list
of the worst IRQ latency offenders anymore, where it was a regular
before.

commit 36e3fa6a38e135e9478a2f75dec9bf6ff1e6480e upstream.
The i2c adapter is only relevant for some peer device types, so
let's clear the pdt if it's still the same as the old_pdt when we
tear down the i2c adapter.
I don't really like this design pattern of updating port->whatever
before doing the accompanying changes and passing around old_whatever
to figure stuff out. Would make much more sense to me to the pass the
new value around and only update the port->whatever when things are
consistent. But let's try to work with what we have right now.
Quoting a follow-up from Ville:
"And naturally I forgot to amend the commit message w.r.t. this guy
[the change in drm_dp_destroy_port]. We don't really need to do this
here, but I figured I'd try to be a bit more consistent by having it,
just to avoid accidental mistakes if/when someone changes this stuff
again later."

commit d721b02fd00bf133580f431b82ef37f3b746dfb2 upstream.
Looks like the TSEG lives just above TOUD, stolen comes after TSEG.
The spec seems somewhat self-contradictory in places, in the ESMRAMC
register desctription it says:
TSEG Size:
10=(TOUD + 512 KB) to TOUD
11 =(TOUD + 1 MB) to TOUD
so that agrees with TSEG being at TOUD. But the example given
elsehwere in the spec says:
TOUD equals 62.5 MB = 03E7FFFFh
TSEG selected as 512 KB in size,
Graphics local memory selected as 1 MB in size
General System RAM available in system = 62.5 MB
General system RAM range00000000h to 03E7FFFFh
TSEG address range03F80000h to 03FFFFFFh
TSEG pre-allocated from03F80000h to 03FFFFFFh
Graphics local memory pre-allocated from03E80000h to 03F7FFFFh
so here we have TSEG above stolen.
Real world evidence agrees with the TOUD->TSEG->stolen order however, so
let's fix up the code to account for the TSEG size.

commit 23f889bdf6ee5cfff012d8b09f6bec920c691696 upstream.
This reverts commit 237ed86c693d8a8e4db476976aeb30df4deac74b.
Our current implementation of live status check (repeat 9 times
with 10ms delays between each attempt as a workaround for
buggy displays) imposes a rather serious penalty, time wise,
on intel_hdmi_detect(). Since we we already skip live status
checks on platforms before gen 7, and since we seem to have
coped quite well before the live status check was introduced
for newer platforms too, the previous behaviour is probably
preferable, at least unless someone can point to a use-case
that the live status check improves (apart from "Bspec says so".)

commit 4e4d3814a9bb4d71cd3ff0701d8d7041edefd8f0 upstream.
Bspec says:
"The mailbox response data may not account for memory read latency.
If the mailbox response data for level 0 is 0us, add 2 microseconds
to the result for each valid level."
This means we should only do the +2 in case wm[0] == 0, not always.
So split the sanitizing implementation from the WA implementation and
fix the WA implementation.
v2: Add Fixes tag (Maarten).

owner from the device->fops instead.

commit 47a66e45d7a7613322549c2475ea9d809baaf514 upstream.
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64). Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.
Note that only the modifier will be packed differently between compat
and non-compat versions.

commit d31ed3f05763644840c654a384eaefa94c097ba2 upstream.
The code is applying the same scaling for the X and Y components,
thus making the scaling feature only functional when both components
have the same scaling factor.
Do the s/_w/_h/ replacement where appropriate to fix vertical scaling.

commit 44eb0cb9620c6a53ec8e7073262e2af8079b727f upstream.
VMA offsets are 64 bits. Plane surface offsets are in ggtt and
the hardware register to set this is thus 32 bits. Be explicit
about these and convert carefully to from vma to final size.
This will make sparse happy by not creating 32bit pointers out
of 64bit vma offsets.

commit 166c5a6ef765653848161e6f4af81c05e4b3ecf6 upstream.
In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to
gma500") the legacy i2c helpers were moved to the only remaining user of
them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus()
was marked deprecated and started warning about its remaining use.
It's now been a year and a half of annoying warning, and apparently
nobody cares enough about gma500 to try to move it along to the more
modern models.
Get rid of the warning - if even the gma500 people don't care enough,
then they should certainly not spam other innocent developers with a
warning that might hide other, much more real issues.

commit 6f00975c619064a18c23fd3aced325ae165a73b9 upstream.
Somehow this one slipped through, which means drivers without modeset
support can be oopsed (since those also don't call
drm_mode_config_init, which means the crtc lookup will chase an
uninitalized idr).

[ Upstream commit 22f35042593c2b369861f0b9740efb8065a42db0 ]
Apparently some CHV boards failed to hook up the port presence straps
for HDMI ports as well (earlier we assumed this problem only affected
eDP ports). So let's check the VBT in addition to the strap, and if
either one claims that the port is present go ahead and register the
relevant connector.
While at it, change port D to register DP before HDMI as we do for ports
B and C since
commit 457c52d87e5d ("drm/i915: Only ignore eDP ports that are connected")
Also print a debug message when we register a HDMI connector to aid
in diagnosing missing/incorrect ports. We already had such a print for
DP/eDP.
v2: Improve the comment in the code a bit, note the port D change in
the commit message

[ Upstream commit 457c52d87e5dac9a4cf1a6a287e60ea7645067d4 ]
If the VBT says that a certain port should be eDP (and hence fused off
from HDMI), but in reality it isn't, we need to try and acquire the HDMI
connection instead. So only trust the VBT edp setting if we can connect
to an eDP device on that port.

[ Upstream commit 0780cd36c7af70c55981ee624084f0f48cae9b95 ]
Looks like g4x hpd live status bits actually agree with the spec. At
least they do on the machine I have, and apparently on Nick Bowler's
g4x as well.
So gm45 may be the only platform where they don't agree. At least
that seems to be the case based on the (somewhat incomplete)
logs/dumps in [1], and Daniel has also tested this on his gm45
sometime in the past.
So let's change the bits to match the spec on g4x. That actually makes
the g4x bits identical to vlv/chv so we can just share the code
between those platforms, leaving gm45 as the special case.
