drm_mode_config_init() simply calls drmm_mode_config_init(), hence
cleanup is automatically handled through registering
drm_mode_config_cleanup() with drmm_add_action_or_reset().
While at it, get rid of the deprecated drm_mode_config_init() and
replace it with drmm_mode_config_init() directly.

Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the
hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM
DMA" seems to be more applicable.
Besides that, commit e57924d4ae ("drm/doc: Task to rename CMA helpers")
requests to rename the CMA helpers and implies that people seem to be
confused about the naming.
In order to do this renaming the following script was used:
```
#!/bin/bash
DIRS="drivers/gpu include/drm Documentation/gpu"
REGEX_SYM_UPPER="[0-9A-Z_\-]"
REGEX_SYM_LOWER="[0-9a-z_\-]"
REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)"
REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)"
REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g"
REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g"
# Find all upper case 'CMA' symbols and replace them with 'DMA'.
for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS)
do
sed -i -E "$REGEX_SED_UPPER" $ff
done
# Find all lower case 'cma' symbols and replace them with 'dma'.
for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS)
do
sed -i -E "$REGEX_SED_LOWER" $ff
done
# Replace all occurrences of 'CMA' / 'cma' in comments and
# documentation files with 'DMA' / 'dma'.
for ff in $(grep -RiHl " cma " $DIRS)
do
sed -i -E "s/ cma / dma /g" $ff
sed -i -E "s/ CMA / DMA /g" $ff
done
# Rename all 'cma_obj's to 'dma_obj'.
for ff in $(grep -RiHl "cma_obj" $DIRS)
do
sed -i -E "s/cma_obj/dma_obj/g" $ff
done
```
Only a few more manual modifications were needed, e.g. reverting the
following modifications in some DRM Kconfig files
- select CMA if HAVE_DMA_CONTIGUOUS
+ select DMA if HAVE_DMA_CONTIGUOUS
as well as manually picking the occurrences of 'CMA'/'cma' in comments and
documentation which relate to "GEM CMA", but not "FB CMA".
Also drivers/gpu/drm/Makefile was fixed up manually after renaming
drm_gem_cma_helper.c to drm_gem_dma_helper.c.
This patch is compile-time tested building a x86_64 kernel with
`make allyesconfig && make drivers/gpu/drm`.

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)

Only when vblanks are supported ofc.
Some drivers do this already, but most unfortunately missed it. This
opens up bugs after driver load, before the crtc is enabled for the
first time. syzbot spotted this when loading vkms as a secondary
output. Given how many drivers are buggy it's best to solve this once
and for all in shared helper code.
Aside from moving the few existing calls to drm_crtc_vblank_reset into
helpers (i915 doesn't use helpers, so keeps its own) I think the
regression risk is minimal: atomic helpers already rely on drivers
calling drm_crtc_vblank_on/off correctly in their hooks when they
support vblanks. And driver that's failing to handle vblanks after
this is missing those calls already, and vblanks could only work by
accident when enabling a CRTC for the first time right after boot.
Big thanks to Tetsuo for helping track down what's going wrong here.
There's only a few drivers which already had the necessary call and
needed some updating:
- komeda, atmel and tidss also needed to be changed to call
__drm_atomic_helper_crtc_reset() intead of open coding it
- tegra and msm even had it in the same place already, just code
motion, and malidp already uses __drm_atomic_helper_crtc_reset().
- Laurent noticed that rcar-du and omap open-code their crtc reset and
hence would actually be broken by this patch now. So fix them up by
reusing the helpers, which brings the drm_crtc_vblank_reset() back.
Only call left is in i915, which doesn't use drm_mode_config_reset,
but has its own fastboot infrastructure. So that's the only case where
we actually want this in the driver still.
I've also reviewed all other drivers which set up vblank support with
drm_vblank_init. After the previous patch fixing mxsfb all atomic
drivers do call drm_crtc_vblank_on/off as they should, the remaining
drivers are either legacy kms or legacy dri1 drivers, so not affected
by this change to atomic helpers.
v2: Use the drm_dev_has_vblank() helper.
v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off
instead of drm_crtc_vblank_reset. Adjust them too.
v4: Laurent noticed that rcar-du and omap open-code their crtc reset
and hence would actually be broken by this patch now. So fix them up
by reusing the helpers, which brings the drm_crtc_vblank_reset() back.
v5: also mention rcar-du and ompadrm in the proper commit message
above (Laurent).

As a result of commit 987d65d013 (drm: debugfs: make
drm_debugfs_create_files() never fail) and changes to various debugfs
functions in drm/core and across various drivers, there is no need for
the drm_driver.debugfs_init() hook to have a return value. Therefore,
declare it as void.
This also includes refactoring all users of the .debugfs_init() hook to
return void across the subsystem.
v2: include changes to the hook and drivers that use it in one patch to
prevent driver breakage and enable individual successful compilation of
this change.

Changes from v1:-
1. Replaced DRM_ERROR() with DRM_DEBUG_KMS() in malidp_format_mod_supported()
to report unsupported modifiers.
Changes from v2:-
1. Removed malidp_format_mod_supported() from the current patch. This has been added
in "PATCH 7/12"
2. Dynamically generate the list of modifiers (to be supported for each plane) from
'malidp_format_modifiers' and features.

Formats like DRM_FORMAT_VUY101010, DRM_FORMAT_YUV420_8BIT and
DRM_FORMAT_YUV420_10BIT are expressed in bits per pixel as they have a non

We need to define a common list of format modifiers supported by each of
the Mali display processors.
The following are the constraints with AFBC:-
1. AFBC is not supported for the formats defined in
malidp_hw_format_is_linear_only()
2. Some of the formats are supported only with AFBC modifiers. Thus we have
introduced a new function 'malidp_hw_format_is_afbc_only()' which verifies
the same.
3. AFBC_FORMAT_MOD_YTR needs to be provided for any RGB format.
4. Formats <= 16bpp cannot support AFBC_FORMAT_MOD_SPLIT.
5. CBR should not be set for non-subsampled formats.
6. SMART layer does not support framebuffer with AFBC modifiers.
Return -EINVAL for such a scenario.
7. AFBC_FORMAT_MOD_YTR is not supported for any YUV formats.
8. Formats which are subsampled cannot support AFBC_FORMAT_MOD_SPLIT.
However in DP550, YUV_420_10BIT is supported with AFBC_FORMAT_MOD_SPLIT.
This feature has been identified with
MALIDP_DEVICE_AFBC_YUV_420_10_SUPPORT_SPLIT.
9. In DP550 and DP650, for YUYV, the hardware supports different
format-ids to be used with and without AFBC modifier. We have used the
feature 'MALIDP_DEVICE_AFBC_YUYV_USE_422_P2' to identify this
characteristic.
10. DP500 does not support split mode (ie AFBC_FORMAT_MOD_SPLIT). We have
used the feature 'MALIDP_DEVICE_AFBC_SUPPORT_SPLIT' to identify the DPs
which support SPLIT mode.
11. DP550 supports YUV420 with split mode. We have defined the feature
'AFBC_SUPPORT_SPLIT_WITH_YUV_420_10' to identify this characteristic.
Changes since v1:-
- Merged https://patchwork.freedesktop.org/patch/265215/ into this patch

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

Currently, if userspace calls drm_wait_vblank before the crtc is
activated the crtc vblank_enable hook is called, which in case of
malidp driver triggers some warninngs. This happens because on
device init we don't inform the drm core about the vblank state
by calling drm_crtc_vblank_on/off/reset which together with
drm_vblank_get have some magic that prevents calling drm_vblank_enable
when crtc is off.

The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().
The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

malidp_pm_suspend_late checks if the runtime status is not suspended
and if so, invokes malidp_runtime_pm_suspend which disables the
display engine/core interrupts and the clocks. It sets the runtime status
as suspended.
The difference between suspend() and suspend_late() is as follows:-
1. suspend() makes the device quiescent. In our case, we invoke the DRM
helper which disables the CRTC. This would have invoked runtime pm
suspend but the system suspend process disables runtime pm.
2. suspend_late() It continues the suspend operations of the drm device
which was started by suspend(). In our case, it performs the same functionality
as runtime_suspend().
The complimentary functions are resume() and resume_early(). In the case of
resume_early(), we invoke malidp_runtime_pm_resume() which enables the clocks
and the interrupts. It sets the runtime status as active. If the device was
in runtime suspend mode before system suspend was called, pm_runtime_work()
will put the device back in runtime suspended mode( after the complete system
has been resumed).

and 2. de_irq - used for display output.

malidp_de_irq_fini on 'struct drm_device' needs to be removed so as to

Status register contains a lot of bits for reporting internal errors
inside Mali DP. Currently, we just silently ignore all of the errors,
that doesn't help when we are investigating different bugs, especially
on the FPGA models which have a lot of constraints, so we could easily
end up in AXI or underrun errors.
Add a new file called debug that contains an aggregate of the
errors reported by the Mali DP hardware.
E.g:
[root@alarm ~]# cat /sys/kernel/debug/dri/1/debug
[DE] num_errors : 167
[DE] last_error_status : 0x00000001
[DE] last_error_vblank : 385
[SE] num_errors : 3
[SE] last_error_status : 0x00e23001
[SE] last_error_vblank : 201

- Add lock to protect the errors stats.
- Add possibility to reset the error stats by writing anything to the
debug file.

Mali DP500 operates in continuous writeback mode (writes frame content
until stopped) and it needs special handling in order to behave like
a one-shot writeback engine. The original state machine added for DP500
was a bit fragile, as it did not handle correctly cases where a new
atomic commit was in progress when the SE IRQ happens and it would
commit some partial updates.
Improve the handling by adding a parameter to the set_config_valid()
function to clear the config valid bit in hardware before starting a
new commit and by introducing a MW_RESTART state in the writeback
state machine to cater for the case where a new writeback commit
gets submitted while the last one is still being active.

Mali DP500 behaves differently from the rest of the Mali DP IP,
in that it does not have a one-shot mode and keeps writing the
content of the current frame to the provided memory area until
stopped. As a way of emulating the one-shot behaviour, we are
going to use the CVAL interrupt that is being raised at the
start of each frame, during prefetch phase, to act as End-of-Write
signal, but with a twist: we are going to disable the memory
write engine right after we're notified that it has been enabled,
using the knowledge that the bit controlling the enabling will
only be acted upon on the next vblank/prefetch.
CVAL interrupt will fire durint the next prefetch phase every time
the global CVAL bit gets set, so we need a state byte to track
the memory write enabling. We also need to pay attention during the
disabling of the memory write engine as that requires the CVAL bit
to be set in the control register, but we don't want to do that
during an atomic commit, as it will write into the hardware a partial
state.

One needs to ensure that the crtcs are shutdown so that the
drm_crtc_state->connector_mask reflects that no connectors
are currently active. Further, it reduces the reference
count for each connector. This ensures that the connectors
and encoders can be cleanly removed either when _unbind
is called for the corresponding drivers or by
drm_mode_config_cleanup().
We need drm_atomic_helper_shutdown() to be called before
component_unbind_all() otherwise the connectors attached to the

As plane cleanup is now handled entirely by drm_mode_config_cleanup(),
we must ensure that the plane .destroy() handler frees allocated memory
for the plane object that was freed by malidp_de_planes_destroy(). Do so

Mali DP hardware has a 'go' bit (config_valid) for making the new scene
parameters active at the next page flip. The problem with the current
code is that the driver first sets this bit and then proceeds to wait
for confirmation from the hardware that the configuration has been
updated before arming the vblank event. As config_valid is actually
asserted by the hardware after the vblank event, during the prefetch
phase, when we get to arming the vblank event we are going to send it
at the next vblank, in effect halving the vblank rate from the userspace
perspective.
Fix it by sending the userspace event from the IRQ handler, when we
handle the config_valid interrupt, which syncs with the time when the
hardware is active with the new parameters.
