drm/meson: fix 1px pink line on GXM when scaling video overlay
Playing media with a resolution smaller than the crtc size requires the
video overlay to be scaled for output and GXM boards display a 1px pink
line on the bottom of the scaled overlay. Comparing with the downstream
vendor driver revealed VPP_DUMMY_DATA not being set [0].
Setting VPP_DUMMY_DATA prevents the 1px pink line from being seen.

Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable.

drm/meson: dw-hdmi: Fix devm_regulator_*get_enable*() conversion
devm_regulator_get_enable_optional() function returns 0 on success, so
use it for the check if function succeeded instead of the -ENODEV value.

drm/meson: Reduce the FIFO lines held when AFBC is not used
Having a bigger number of FIFO lines held after vsync is only useful to
SoCs using AFBC to give time to the AFBC decoder to be reset, configured
and enabled again.
For SoCs not using AFBC this, on the contrary, is causing on some
displays issues and a few pixels vertical offset in the displayed image.
Conditionally increase the number of lines held after vsync only for
SoCs using AFBC, leaving the default value for all the others.

drm/fb-helper: Move generic fbdev emulation into separate source file
Move the generic fbdev implementation into its own source and header
file. Adapt drivers. No functional changes, but some of the internal
helpers have been renamed to fit into the drm_fbdev_ naming scheme.
v3:
* rename drm_fbdev.{c,h} to drm_fbdev_generic.{c,h}
* rebase onto vmwgfx changes
* rebase onto xlnx changes
* fix include statements in amdgpu

drm/meson: Fix return type of meson_encoder_cvbs_mode_valid()
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed. A
proposed warning in clang aims to catch these at compile time, which
reveals:
drivers/gpu/drm/meson/meson_encoder_cvbs.c:211:16: error: incompatible function pointer types initializing 'enum drm_mode_status (*)(struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' with an expression of type 'int (struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' [-Werror,-Wincompatible-function-pointer-types-strict]
.mode_valid = meson_encoder_cvbs_mode_valid,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
->mode_valid() in 'struct drm_bridge_funcs' expects a return type of
'enum drm_mode_status', not 'int'. Adjust the return type of
meson_encoder_cvbs_mode_valid() to match the prototype's to resolve the
warning and CFI failure.

drm/meson: remove drm bridges at aggregate driver unbind time
drm bridges added by meson_encoder_hdmi_init and meson_encoder_cvbs_init were not manually removed at module unload time, which caused dangling references to freed memory to remain linked in the global bridge_list.

drm/meson: explicitly remove aggregate driver at module unload time
Because component_master_del wasn't being called when unloading the meson_drm module, the aggregate device would linger forever in the global aggregate_devices list. That means when unloading and reloading the meson_dw_hdmi module, component_add would call into try_to_bring_up_aggregate_device and find the unbound meson_drm aggregate device. This would in turn dereference some of the aggregate_device's struct entries which point to memory automatically freed by the devres API when unbinding the aggregate device from meson_drv_unbind, and trigger an use-after-free bug: [ +0.000014] ============================================================= [ +0.000007] BUG: KASAN: use-after-free in find_components+0x468/0x500 [ +0.000017] Read of

================================================================== The reason this is happening is unloading meson-dw-hdmi will cause the component API to take down the aggregate device, which in turn will cause all devres-managed memory to be freed, including the struct dw_hdmi allocated in dw_hdmi_probe. This struct embeds a struct drm_bridge that is added at the end of the function, and which is later on picked up in meson_encoder_hdmi_init. However, when attaching the bridge to the encoder created in meson_encoder_hdmi_init, it's linked to the encoder's bridge chain, from where it never leaves, even after devres_release_group is called when the driver's components are unbound and the embedding structure freed. Then, when calling drm_dev_put in the aggregate driver's unbind function, drm_bridge_detach is called for every single bridge linked to the encoder, including the one whose memory had already been deallocated. Fix by calling component_unbind_all after drm_dev_put.

drm/meson: Fix OSD1 RGB to YCbCr coefficient
VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
not 16-28.
Without this the output tends to have a pink hue, changing it results
in better color accuracy.
The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,
which do use bits 16-28 for this coefficient, but those have names
ending in MATRIX_COEF22_30, and this is not one of those.

asm-generic: updates for 6.0
There are three independent sets of changes:
- Sai Prakash Ranjan adds tracing support to the asm-generic
version of the MMIO accessors, which is intended to help
understand problems with device drivers and has been part
of Qualcomm's vendor kernels for many years.
- A patch from Sebastian Siewior to rework the handling of
IRQ stacks in softirqs across architectures, which is
needed for enabling PREEMPT_RT.
- The last patch to remove the CONFIG_VIRT_TO_BUS option and
some of the code behind that, after the last users of this
old interface made it in through the netdev, scsi, media and
staging trees.

drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}
The field paddr of struct drm_gem_dma_object holds a DMA address, which
might actually be a physical address. However, depending on the platform,
it can also be a bus address or a virtual address managed by an IOMMU.
Hence, rename the field to dma_addr, which is more applicable.
In order to do this renaming the following coccinelle script was used:
```
@@
struct drm_gem_dma_object *gem;
@@
- gem->paddr
+ gem->dma_addr
@@
struct drm_gem_dma_object gem;

- gem.paddr

@@
symbol paddr;

This patch is compile-time tested with:
```

drm/meson: add YUV422 output support
Support YUV422 output from the Amlogic Meson SoC VPU to the HDMI controller. Without this YUV422 format out of the HDMI encoder leads to using the dw-hdmi YUV444 to YUV422 color conversion which gives wrong colors and a green line on the left edge of the screen.

Driver core changes for 5.18-rc1
Here is the set of driver core changes for 5.18-rc1.
Not much here, primarily it was a bunch of cleanups and small updates:
- kobj_type cleanups for default_groups
- documentation updates
- firmware loader minor changes
- component common helper added and take advantage of it in many
drivers (the largest part of this pull request).
There will be a merge conflict in drivers/power/supply/ab8500_chargalg.c
with your tree, the merge conflict should be easy (take all the
changes).
All of these have been in linux-next for a while with no reported
problems.

drm/meson: encoder_hdmi: switch to bridge DRM_BRIDGE_ATTACH_NO_CONNECTOR
This implements the necessary change to no more use the embedded connector in dw-hdmi and use the dedicated bridge connector driver by passing DRM_BRIDGE_ATTACH_NO_CONNECTOR to the bridge attach call. The necessary connector properties are added to handle the same functionalities as the embedded dw-hdmi connector, i.e. the HDR metadata, the CEC notifier & other flags. The dw-hdmi output_port is set to 1 in order to look for a connector next bridge in order to get DRM_BRIDGE_ATTACH_NO_CONNECTOR working.

drm/meson: split out encoder from meson_dw_hdmi
This moves all the non-DW-HDMI code where it should be: an encoder in the drm/meson core driver. The bridge functions are copied as-is, except: - the encoder init uses the simple kms helper - the mode_set has been moved to atomic_enable() - debug prints are converted to dev_debg() For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR will be handled later.

Pull drm updates from Dave Airlie:
"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.

Add support for the OSD1 HDR registers so meson DRM can handle the HDR
properties set by Amlogic u-boot on G12A and newer devices which result
in blue/green/pink colour distortion to display output.
This takes the original patch submissions from Mathias [0] and [1] with
corrections for formatting and the missing description and attribution
needed for merge.

drm: Use state helper instead of the plane state pointer
Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.
Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.
This was made using the coccinelle script below:

drm/atomic: Pass the full state to planes atomic disable and update
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.
The conversion was done using the coccinelle script below, built tested on
all the drivers.

drm: Rename plane->state variables in atomic update and disable
Some drivers are storing the plane->state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.
In order to ease subsequent reworks and to avoid confusing or
inconsistent names, let's rename those variables to new_state.
This was done using the following coccinelle script, plus some manual
changes for mtk and tegra.

drm/atomic: Pass the full state to planes atomic_check
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.
The conversion was done using the coccinelle script below plus some
manual changes for vmwgfx, built tested on all the drivers.

drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210222141756.7864-1-tzimmermann@suse.de |

Instead of moving meson_dw_hdmi_init() around which breaks existing

This means we don't have to worry about this clock being enabled or
not, depending on the boot-loader features.

drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP registers
Removing the meson-dw-hdmi module and re-inserting it results in a hang
as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen
when booting with mainline u-boot and using the u-boot provided DT (which
is highly desirable).
The reason for the hang seem to be that the clocks are not always
enabled by the time we enter meson_dw_hdmi_init(). Moving this call
*after* dw_hdmi_probe() ensures that the clocks are enabled.

drm/<drivers>: Constify struct drm_driver
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch |

drm/atomic: Pass the full state to CRTC atomic begin and flush
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's start convert all the remaining helpers to provide a consistent
interface, starting with the CRTC's atomic_begin and atomic_flush.
The conversion was done using the coccinelle script below, built tested on
all the drivers and actually tested on vc4.

drm/atomic: Pass the full state to CRTC atomic enable/disable
If the CRTC driver ever needs to access the full DRM state, it can't do so
at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state
will have cleared the pointer from the struct drm_crtc_state to the struct
drm_atomic_state before calling those hooks.
In order to allow that, let's pass the full DRM state to atomic_enable and
atomic_disable. The conversion was done using the coccinelle script below,
built tested on all the drivers and actually tested on vc4.

drm/meson: overlay: fix build failure
The recent GCC compiler is very picky with the VD_H_START() and
AFBC_DEC_PIXEL_BGN_H() macros, triggering a runtime assert error as:
In function 'meson_overlay_setup_scaler_params',
inlined from 'meson_overlay_atomic_update' at
drivers/gpu/drm/meson/meson_overlay.c:542:2:
./include/linux/compiler.h:392:38: error: call to
'__compiletime_assert_341' declared with attribute error: FIELD_PREP:
value too large for the field
drivers/gpu/drm/meson/meson_overlay.c:413:4: note: in expansion of macro
'AFBC_DEC_PIXEL_BGN_H'
413 | AFBC_DEC_PIXEL_BGN_H(hd_start_lines - afbc_left) |
| ^~~~~~~~~~~~~~~~~~~~
./include/linux/compiler.h:392:38: error: call to
'__compiletime_assert_401' declared with attribute error: FIELD_PREP:
value too large for the field
It's not expected to overflow these fields, but the compiler did
find a case where it overflows.
We can safely ignore this, so mask the value with the field width.

drm/meson: viu: fix setting the OSD burst length in VIU_OSD1_FIFO_CTRL_STAT
The burst length is configured in VIU_OSD1_FIFO_CTRL_STAT[31] and
VIU_OSD1_FIFO_CTRL_STAT[11:10]. The public S905D3 datasheet describes
this as:
- 0x0 = up to 24 per burst
- 0x1 = up to 32 per burst
- 0x2 = up to 48 per burst
- 0x3 = up to 64 per burst
- 0x4 = up to 96 per burst
- 0x5 = up to 128 per burst
The lower two bits map to VIU_OSD1_FIFO_CTRL_STAT[11:10] while the upper
bit maps to VIU_OSD1_FIFO_CTRL_STAT[31].
Replace meson_viu_osd_burst_length_reg() with pre-defined macros which
set these values. meson_viu_osd_burst_length_reg() always returned 0
(for the two used values: 32 and 64 at least) and thus incorrectly set
the burst size to 24.

- Remove the now empty loop in drm_helper_probe_single_connector_modes()
- Fix __MODE() macro in ch7006_mode.c
- Fix DRM_MODE_ARG() macro in drm_modes.h
- Remove leftover comment from samsung_s6d16d0_mode
