Kai-Heng Feng 227545b9a0 drm/radeon/dpm: Disable sclk switching on Oland when two 4K 60Hz monitors are connected
Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue
doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and
another one is 4K 30Hz (pixelclock 297MHz).

The issue is gone after setting "power_dpm_force_performance_level" to
"high". Following the indication, we found that the issue occurs when
sclk is too low.

So resolve the issue by disabling sclk switching when there are two
monitors requires high pixelclock (> 297MHz).

v2:
 - Only apply the fix to Oland.

David Ward fe1c97d008 drm/amd/display: Initialize attribute for hdcp_srm sysfs file
It is stored in dynamically allocated memory, so sysfs_bin_attr_init() must
be called to initialize it. (Note: "initialization" only sets the .attr.key
member in this struct; it does not change the value of any other members.)

Otherwise, when CONFIG_DEBUG_LOCK_ALLOC=y this message appears during boot:

Gustavo A. R. Silva 939baec9e8 drm/amd/pm: Fix out-of-bounds bug
Create new structure SISLANDS_SMC_SWSTATE_SINGLE, as initialState.levels
and ACPIState.levels are never actually used as flexible arrays. Those
arrays can be used as simple objects of type
SISLANDS_SMC_HW_PERFORMANCE_LEVEL, instead.

Currently, the code fails because flexible array _levels_ in
struct SISLANDS_SMC_SWSTATE doesn't allow for code that accesses
the first element of initialState.levels and ACPIState.levels
arrays:

drivers/gpu/drm/amd/pm/powerplay/si_dpm.c:
4820: table->initialState.levels[0].mclk.vDLL_CNTL =
4821:         cpu_to_be32(si_pi->clock_registers.dll_cntl);
...
5021: table->ACPIState.levels[0].mclk.vDLL_CNTL =
5022:         cpu_to_be32(dll_cntl);

because such element cannot be accessed without previously allocating
enough dynamic memory for it to exist (which never actually happens).
So, there is an out-of-bounds bug in this case.

That's why struct SISLANDS_SMC_SWSTATE should only be used as type
for object driverState and new struct SISLANDS_SMC_SWSTATE_SINGLE is
created as type for objects initialState, ACPIState and ULVState.

Also, with the change from one-element array to flexible-array member
in commit 0e1aa13ca3 ("drm/amd/pm: Replace one-element array with
flexible-array in struct SISLANDS_SMC_SWSTATE"), the size of
dpmLevels in struct SISLANDS_SMC_STATETABLE should be fixed to be
SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE instead of
SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE - 1.

function to store flags. However, the auto_retire function is not
guaranteed to be aligned to a multiple of 4, which causes crashes as
we jump to the wrong address, for example like this:

Lv Yunlong ea995218dd drm/i915/gt: Fix a double free in gen8_preallocate_top_level_pdp
Our code analyzer reported a double free bug.

In gen8_preallocate_top_level_pdp, pde and pde->pt.base are allocated
via alloc_pd(vm) with one reference. If pin_pt_dma() failed, pde->pt.base
is freed by i915_gem_object_put() with a reference dropped. Then free_pd
calls free_px() defined in intel_ppgtt.c, which calls i915_gem_object_put()
to put pde->pt.base again.

As pde->pt.base is protected by refcount, so the second put will not free
pde->pt.base actually. But, maybe it is better to remove the first put?

Ville Syrjälä 4819d16d91 drm/i915: Avoid div-by-zero on gen2
Gen2 tiles are 2KiB in size so i915_gem_object_get_tile_row_size()
can in fact return <4KiB, which leads to div-by-zero here.
Avoid that.

Not sure i915_gem_object_get_tile_row_size() is entirely
sane anyway since it doesn't account for the different tile
layouts on i8xx/i915...

I'm not able to hit this before commit 6846895fde ("drm/i915:
Replace PIN_NONFAULT with calls to PIN_NOEVICT") and it looks
like I also need to run recent version of Mesa. With those in
place xonotic trips on this quite easily on my 85x.

Kai-Heng Feng a5c936add6 drm/i915/dp: Use slow and wide link training for everything
Screen flickers on Innolux eDP 1.3 panel when clock rate 540000 is in use.

According to the panel vendor, though clock rate 540000 is advertised,
but the max clock rate it really supports is 270000.

Ville Syrjälä mentioned that fast and narrow also breaks some eDP 1.4
panel, so use slow and wide training for all panels to resolve the
issue.

User also confirmed that the new strategy doesn't introduce any
regression on XPS 9380.

v2:
 - Use slow and wide for everything.

Linus Torvalds fec4d42724 drm/i915/display: fix compiler warning about array overrun
intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().

End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer.  gcc-11 correctly warns
about this case:

  drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_check_mst_status’:
  drivers/gpu/drm/i915/display/intel_dp.c:3491:22: warning: ‘drm_dp_channel_eq_ok’ reading 6 bytes from a region of size 4 [-Wstringop-overread]

        |      ^~~~~~~~~~~~~~~~~~~~
       6:14 elapsed

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.

There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use
random data off the stack.

Masahiro Yamada fa60ce2cb4 treewide: remove editor modelines and cruft
The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."

I recently receive a patch to explicitly add a new one.

Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.

It is even nicer if scripts/checkpatch.pl can check it.

If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.

Bas Nieuwenhuizen 234055fd97 drm/amdgpu: Use device specific BO size & stride check.
The builtin size check isn't really the right thing for AMD
modifiers due to a couple of reasons:

1) In the format structs we don't do set any of the tilesize / blocks
etc. to avoid having format arrays per modifier/GPU
2) The pitch on the main plane is pixel_pitch * bytes_per_pixel even
for tiled ...
3) The pitch for the DCC planes is really the pixel pitch of the main
surface that would be covered by it ...

Note that we only handle GFX9+ case but we do this after converting
the implicit modifier to an explicit modifier, so on GFX9+ all
framebuffers should be checked here.

There is a TODO about DCC alignment, but it isn't worse than before
and I'd need to dig a bunch into the specifics. Getting this out in
a reasonable timeframe to make sure it gets the appropriate testing
seemed more important.

Finally as I've found that debugging addfb2 failures is a pita I was
generous adding explicit error messages to every failure case.

Rodrigo Siqueira 16e9b3e58b drm/amd/display: Fix two cursor duplication when using overlay
Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.

For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:

  +-------------+   +--------------+
  | +---------+ |   |              |
  | |Primary  | |   | Primary      |
  | |         | |   | Overlay      |
  | +---------+ |   |              |
  |Overlay      |   |              |
  +-------------+   +--------------+

In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):

                                      +--------+
                                      |Overlay |
 +-------------+    +-----+-------+ +-|        |--+
 | +--------+  | +--------+       | | +--------+  |
 | |Overlay |  | |Overlay |       | |             |
 | |        |  | |        |       | |             |
 | +--------+  | +--------+       | |             |
 | Primary     |    | Primary     | | Primary     |
 +-------------+    +-------------+ +-------------+

 +-------------+   +-------------+
 |     +--------+  |  Primary    |
 |     |Overlay |  |             |
 |     |        |  |             |
 |     +--------+  | +--------+  |
 | Primary     |   | |Overlay |  |
 +-------------+   +-|        |--+
                     +--------+

If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.

Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.

drm/msm/dpu: Delete bonkers code
dpu_crtc_atomic_flush() was directly poking it's attached planes in a
code path that ended up in dpu_plane_atomic_update(), even if the plane
was not involved in the current atomic update.  While a bit dubious,
this worked before because plane->state would always point to something
valid.  But now using drm_atomic_get_new_plane_state() we could get a
NULL state pointer instead, leading to:

The reason for the codepath seems dubious, the atomic suspend/resume
heplers should handle the power-collapse case.  If not, the CRTC's
atomic_check() should be adding the planes to the atomic update.

Including:
 
 	- Big cleanup of almost unsused parts of the IOMMU API by
 	  Christoph Hellwig. This mostly affects the Freescale PAMU
 	  driver.
 
 	- New IOMMU driver for Unisoc SOCs
 
 	- ARM SMMU Updates from Will:
 
 	  - SMMUv3: Drop vestigial PREFETCH_ADDR support
 	  - SMMUv3: Elide TLB sync logic for empty gather
 	  - SMMUv3: Fix "Service Failure Mode" handling
     	  - SMMUv2: New Qualcomm compatible string
 
 	- Removal of the AMD IOMMU performance counter writeable check
 	  on AMD. It caused long boot delays on some machines and is
 	  only needed to work around an errata on some older (possibly
 	  pre-production) chips. If someone is still hit by this
 	  hardware issue anyway the performance counters will just
 	  return 0.
 
 	- Support for targeted invalidations in the AMD IOMMU driver.
 	  Before that the driver only invalidated a single 4k page or the
 	  whole IO/TLB for an address space. This has been extended now
 	  and is mostly useful for emulated AMD IOMMUs.
 
 	- Several fixes for the Shared Virtual Memory support in the
 	  Intel VT-d driver
 
 	- Mediatek drivers can now be built as modules
 
 	- Re-introduction of the forcedac boot option which got lost
 	  when converting the Intel VT-d driver to the common dma-iommu
 	  implementation.
 
 	- Extension of the IOMMU device registration interface and
 	  support iommu_ops to be const again when drivers are built as
 	  modules.

Christoph Hellwig b12d691ea5 i915: fix remap_io_sg to verify the pgprot
remap_io_sg claims that the pgprot is pre-verified using an io_mapping,
but actually does not get passed an io_mapping and just uses the pgprot in
the VMA.  Remove the apply_to_page_range abuse and just loop over
remap_pfn_range for each segment.

Note: this could use io_mapping_map_user by passing an iomap to
remap_io_sg if the maintainers can verify that the pgprot in the iomap in
the only caller is indeed the desired one here.

Christoph Hellwig b739f125e4 i915: use io_mapping_map_user
Replace the home-grown remap_io_mapping that abuses apply_to_page_range
with the proper io_mapping_map_user interface.

Dave Airlie 12fc11bce6 drm/tegra: Changes for v5.13-rc1
The changes this time around contain a couple of fixes for host1x along
 with some improvements for Tegra DRM. Most notably the Tegra DRM driver
 now supports the hardware cursor on Tegra186 and later, more correctly
 reflects the capabilities of the display pipelines on various Tegra SoC
 generations and knows how to deal with the dGPU sector layout by using
 framebuffer modifiers.

Colin Xu d385c16173 drm/i915/gvt: Prevent divided by zero when calculating refresh rate
To get refresh rate as vblank timer period and keep the precision, the
calculation of rate is multiplied by 1000. However old logic was using:
rate = pixel clock / (h * v / 1000). When the h/v total is invalid, like
all 0, h * v / 1000 will be rounded to 0, which leads to a divided by 0
fault.

0 H/V are already checked above. Instead of divide after divide, refine
the calculation to divide after multiply: "pixel clock * 1000 / (h * v)"
Guest driver should guarantee the correctness of the timing regs' value.
