[ Upstream commit fd1a5e521c3c083bb43ea731aae0f8b95f12b9bd ]

psbfb_probe performs an evaluation of the required size from the stolen
GTT memory, but gets it wrong in two distinct ways:
- The resulting size must be page-size-aligned;
- The size to allocate is derived from the surface dimensions, not the fb
  dimensions.

When two connectors are connected with different modes, the smallest will
be stored in the fb dimensions, but the size that needs to be allocated must
match the largest (surface) dimensions. This is what is used in the actual
allocation code.

Fix this by correcting the evaluation to conform to the two points above.
It allows correctly switching to 16bpp when one connector is e.g. 1920x1080
and the other is 1024x768.

ioremap on line 178 and execution via conditional on line 185

Generated by: scripts/coccinelle/free/iounmap.cocci

A jump target was specified in an if branch. The corresponding function
call did not release the desired system resource then.
Thus use the label “rom_unmap” instead to fix the exception handling
for this function implementation.

From: Nikola Cornij <nikola.cornij@amd.com>

[ Upstream commit ec5b356c58941bb8930858155d9ce14ceb3d30a0 ]

[why]
Up to 4 ODM memory pieces are required per ODM combine and cannot
overlap, i.e. each ODM "session" has to use its own memory pieces.
The ODM-memory mapping is currently broken for generic case.

The maximum number of memory pieces is ASIC-dependent, but it's always
big enough to satisfy maximum number of ODM combines. Memory pieces
are mapped as a bit-map, i.e. one memory piece corresponds to one bit.
The OPTC doing ODM needs to select memory pieces by setting the
corresponding bits, making sure there's no overlap with other OPTC
instances that might be doing ODM.

The current mapping works only for OPTC instance indexes smaller than
3. For instance indexes 3 and up it practically maps no ODM memory,
causing black, gray or white screen in display configs that include
ODM on OPTC instance 3 or up.

[how]
Statically map two unique ODM memory pieces for each OPTC instance
and piece them together when programming ODM combine mode.

[ Upstream commit 2ce18249af5a28031b3f909cfafccc88ea966c9d ]

When configuring the frame memory window, the last column and row
numbers are written to the column resp. page address registers.  These
numbers are thus one less than the actual window width resp. height.

While this is handled correctly in mipi_dbi_fb_dirty() since commit
03ceb1c8dfd1e293 ("drm/tinydrm: Fix setting of the column/page end
addresses."), it is not in mipi_dbi_blank().  The latter still forgets
to subtract one when calculating the most significant bytes of the
column and row numbers, thus programming wrong values when the display
width or height is a multiple of 256.

[ Upstream commit 15ab987c423df561e0949d77fb5043921ae59956 ]

We can have two cases, when it comes to "zap" fw.  Either the fw
requires zap fw to take the GPU out of secure mode at boot, or it does
not and we can write RBBM_SECVID_TRUST_CNTL directly.  Previously we
decided based on whether zap fw load succeeded, but this is not a great
plan because:

1) we could have zap fw in the filesystem on a device where it is not
   required
2) we could have the inverse case

Instead, shift to deciding based on whether we have a 'zap-shader' node
in dt.  In practice, there is only one device (currently) with upstream
dt that does not use zap (cheza), and it already has a /delete-node/ for
the zap-shader node.

[ Upstream commit 3c911fe799d1c338d94b78e7182ad452c37af897 ]

In the probe function, some resources are allocated using 'dma_alloc_wc()',
they should be released with 'dma_free_wc()', not 'dma_free_coherent()'.

We already use 'dma_free_wc()' in the remove function, but not in the
error handling path of the probe function.

Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already
PAGE_ALIGNed.

The sizeof is currently on args.src and args.dst and should be on
*args.src and *args.dst. Fortunately these sizes just so happen
to be the same size so it worked, however, this should be fixed
and it also cleans up static analysis warnings

[why]
Upon exiting a fixed active VRR state, the state isn't cleared. This
leads to the variable VRR range to be calculated incorrectly.

[how]
Set fixed active state to false when updating vrr params

From: Harry Wentland <harry.wentland@amd.com>

[ Upstream commit 3eb6d7aca53d81ce888624f09cd44dc0302161e8 ]

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.

A year ago this was partly remedied with:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")

This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).

This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.

In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.

[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.

With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")

From: Yong Zhao <Yong.Zhao@amd.com>

[ Upstream commit f38abc15d157b7b31fa7f651dc8bf92858c963f8 ]

The sdma_queue_count increment should be done before
execute_queues_cpsch(), which calls pm_calc_rlib_size() where
sdma_queue_count is used to calculate whether over_subscription is
triggered.

With the previous code, when a SDMA queue is created,
compute_queue_count in pm_calc_rlib_size() is one more than the
actual compute queue number, because the queue_count has been
incremented while sdma_queue_count has not. This patch fixes that.

[ Upstream commit 4bf321c177c74f7d834956387cd74805c3098322 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c: In function vega10_get_performance_level:
drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c:5217:23: warning: variable data set but not used [-Wunused-but-set-variable]

'data' is introduced by commit f688b614b643 ("drm/amd/pp:
Implement get_performance_level for legacy dgpu"), but never used,
so remove it.

[ Upstream commit a63141e31764f8daf3f29e8e2d450dcf9199d1c8 ]

Commit b0f3cd3191cd ("drm/amdgpu: remove unnecessary JPEG2.0 code from
VCN2.0") introduced a new clang warning in the vcn_v2_0_stop function:

../drivers/gpu/drm/amd/amdgpu/vcn_v2_0.c:1082:2: warning: variable 'r'

To prevent warnings like this from happening in the future, make the
SOC15_WAIT_ON_RREG macro initialize its ret variable before the while
loop that can time out. This macro's return value is always checked so
it should set ret in both the success and fail path.

[ Upstream commit 0d35408afbeb603bc9972ae91e4dd2638bcffe52 ]

Previously, there was an omap panel-dpi driver that would
read generic timings from the device tree and set the display
timing accordingly.  This driver was removed so the screen
no longer functions.  This patch modifies the panel-simple
file to setup the timings to the same values previously used.

Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver")

issues:
MEC is ruined by the amdkfd_pre_reset after VF FLR done

fix:
amdkfd_pre_reset() would ruin MEC after hypervisor finished the VF FLR,
the correct sequence is do amdkfd_pre_reset before VF FLR but there is
a limitation to block this sequence:
if we do pre_reset() before VF FLR, it would go KIQ way to do register
access and stuck there, because KIQ probably won't work by that time
(e.g. you already made GFX hang)

so the best way right now is to simply remove it.

[ Upstream commit 411f5c1eacfebb1f6e40b653d29447cdfe7282aa ]

The driver currently handles vblank events only when updating planes on
an already enabled CRTC. The atomic update API however allows requesting
an event when enabling or disabling a CRTC. This currently leads to

From: Manasi Navare <manasi.d.navare@intel.com>

[ Upstream commit f25c7a006cd1c07254780e3406e45cee4842b933 ]

In case of tiled displays, if we hotplug just one connector,
fbcon currently just selects the preferred mode and if it is
tiled mode then that becomes a problem if rest of the tiles are
not present.
So in the fbdev driver on hotplug when we probe the client modeset,
if we dont find all the connectors for all tiles, then on a connector
with one tile, just fallback to the first available non tiled mode
to display over a single connector.
On the hotplug of the consecutive tiled connectors, if the tiled mode
no longer exists because of fbcon size limitation, then return
no modes for consecutive tiles but retain the non tiled mode
on the 0th tile.
Use the same logic in case of connected boot case as well.
This has been tested with Dell UP328K tiled monitor.

v2:
* Set the modes on consecutive hotplugged tiles to no mode
if tiled mode is pruned (Dave)
v1:
* Just handle the 1st connector hotplug case
* v1 Reviewed-by: Dave Airlie <airlied@redhat.com>

[ Upstream commit 3613a9bea95a1470dd42e4ed1cc7d86ebe0a2dc0 ]

We accidentally set "psb" which is a no-op instead of "*psb" so it
generates a static checker warning.  We should probably set it before
the first error return so that it's always initialized.

[ Upstream commit 7adc77aa0e11f25b0e762859219c70852cd8d56f ]

Method init is typically ordered by class in the FW image as ThreeD,
TwoD, Compute.

Due to a bug in parsing the FW into our internal format, we've been
accidentally sending Twod + Compute methods to the ThreeD class, as
well as Compute methods to the TwoD class - oops.

[ Upstream commit 0e6176c6d286316e9431b4f695940cfac4ffe6c2 ]

The implementations for most channel types contains a map of methods to
priv registers in order to provide debugging info when a disp exception
has been raised.

This info is missing from the implementation of PIO channels as they're
rather simplistic already, however, if an exception is raised by one of
them, we'd end up triggering a NULL-pointer deref.  Not ideal...

[ Upstream commit ec3d65082d7dabad6fa8f66a8ef166f2d522d6b2 ]

Per at least one tester this is enough magic to recover the regression
introduced for some people (but not all) in

commit b8e2b0199cc377617dc238f5106352c06dcd3fa2
Author: Peter Rosin <peda@axentia.se>
Date:   Tue Jul 4 12:36:57 2017 +0200

    drm/fb-helper: factor out pseudo-palette

which for radeon had the side-effect of refactoring out a seemingly
redudant writing of the color palette.

10ms in a fairly slow modeset path feels like an acceptable form of
duct-tape, so maybe worth a shot and see what sticks.
