Unbreak the DRM menu. This Kconfig symbol does not depend on DRM,
so the menu is broken at that point.
Move the symbol to a location in the Kconfig file so that it does
not break the dependency continuity.
Fixes: 6349120ddcbf ("drm: Move EXPORT_SYMBOL_FOR_TESTS_ONLY under a separate Kconfig")

This patch adds a new DRM driver for Texas Instruments DSS IPs used on
Texas Instruments Keystone K2G, AM65x, and J721e SoCs. The new DSS IP is
a major change to the older DSS IP versions, which are supported by
the omapdrm driver. While on higher level the Keystone DSS resembles
the older DSS versions, the registers are completely different and the
internal pipelines differ a lot.
DSS IP found on K2G is an "ultra-light" version, and has only a single
plane and a single output. The K3 DSS IPs are found on AM65x and J721E
SoCs. AM65x DSS has two video ports, one full video plane, and another
"lite" plane without scaling support. J721E has 4 video ports, 2 video
planes and 2 lite planes. AM65x DSS has also an integrated OLDI (LVDS)
output.
Version history:
v2: - rebased on top of drm-next-2019-11-27
- sort all include lines in all files
- remove all include <drm/drmP.h>
- remove select "select VIDEOMODE_HELPERS"
- call dispc_vp_setup() later in tidss_crtc_atomic_flush() (there is no
to call it in new modeset case as it is also called in vp_enable())
- change probe sequence and drm_device allocation (follow example in
drm_drv.c)
- use __maybe_unused instead of #ifdef for pm functions
- remove "struct drm_fbdev_cma *fbdev;" from driver data
- check panel connector type before connecting it
v3: no change
v4: no change
v5: - remove fifo underflow irq handling, it is not an error and
it should be used for debug purposes only
- memory tuning, prefetch plane fifo up to high-threshold value to
minimize possibility of underflows.
v6: - Check CTM and gamma support from dispc_features when creating crtc
- Implement CTM support for k2g and fix k3 CTM implementation
- Remove gamma property persistence and always write color properties
in a new modeset
v7: - Fix checkpatch.pl --strict issues
- Rebase on top of drm-misc-next-2020-01-10
v8: - Remove idle debug prints from dispc_init()
- Add Reviewed-by: Benoit Parrot <bparrot@ti.com>
v9: - Rename dispc_write_irqenable() to dispc_set_irqenable() to avoid
conflict exported omapfb function with same name

Add a missing 'depends on DRM' for the DRM_DP_CEC config
option. Without that enabling DRM_DP_CEC will force CEC_CORE
to =y instead of =m if DRM=m as well.

Currently, we only export symbols for drm-selftests which are either
compiled as modules or into the main drm builtin. However, if we want to
export symbols from drm.ko for the drivers' selftests, we require a
means of controlling that export separately. So we add a new Kconfig to
determine whether or not the EXPORT_SYMBOL_FOR_TESTS_ONLY() takes
effect.

The ATI Rage 128 driver has been the only user of ATI PCI GART code
since Radeon dropped UMS support in commit 8333f607a631 ("drm/radeon:
remove UMS support"). Clean up the drm top level directory, Kconfig and
Makefile by making ati_pcigart.[ch] part of r128. Drop the
CONFIG_DRM_ATI_PCIGART config option made redundant by the change.
This reduces drm.ko module size slightly when legacy drivers are
enabled, and moves the baggage to r128.ko instead.

UAPI Changes:
Cross-subsystem Changes:
Core Changes:
* Handle UP requests asynchronously in the DP MST helpers, fixing
hotplug notifications and allowing us to implement suspend/resume
reprobing
* Add basic suspend/resume reprobing to the DP MST helpers
* Improve locking for link address reprobing and connection status
request handling in the DP MST helpers
* Miscellaneous refactoring in the DP MST helpers
* Add a Kconfig option to the DP MST helpers to enable tracking of
gets/puts for topology references for debugging purposes
Driver Changes:
* nouveau: Resume hotplug interrupts earlier, so that sideband
messages may be transmitted during resume and thus allow
suspend/resume reprobing for DP MST to work
* nouveau: Avoid grabbing runtime PM references when handling short DP
pulses, so that handling sideband messages in resume codepaths with the
DP MST helpers doesn't deadlock us
* i915, nouveau, amdgpu, radeon: Use detect_ctx for probing MST
connectors, so that we can grab the topology manager's atomic lock
Note: there's some amdgpu patches that I didn't realize were pushed
upstream already when creating this topic branch. When they fail to
apply, you can just ignore and skip them.

For very subtle mistakes with topology refs, it can be rather difficult
to trace them down with the debugging info that we already have. I had
one such issue recently while trying to implement suspend/resume
reprobing for MST, and ended up coming up with this.
Inspired by Chris Wilson's wakeref tracking for i915, this adds a very
similar feature to the DP MST helpers, which allows for partial tracking
of topology refs for both ports and branch devices. This is a lot less
advanced then wakeref tracking: we merely keep a count of all of the
spots where a topology ref has been grabbed or dropped, then dump out
that history in chronological order when a port or branch device's
topology refcount reaches 0. So far, I've found this incredibly useful
for debugging topology refcount errors.
Since this has the potential to be somewhat slow and loud, we add an
expert kernel config option to enable or disable this feature,
CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS.
Changes since v1:
* Don't forget to destroy topology_ref_history_lock
Changes since v4:
* Correct order of kref_put()/topology_ref_history_unlock - we can't
unlock the history after kref_put() since the memory might have been
freed by that point
* Don't print message on allocation error failures, the kernel already
does this for us
Changes since v5:
* Get rid of some leftover usages of %px
* Remove a leftover empty return; statement

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by
CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same
functionality which today depends on CONFIG_PREEMPT.
Change the Kconfig dependency of i810 to !CONFIG_PREEMPTION so the driver
is not accidentally built on a RT kernel.

Now with ttm_buffer_object being a subclass of drm_gem_object we can
easily lookup ttm_buffer_object for a given drm_gem_object, which in
turn allows to create common helper functions.
This patch starts off with a drm_gem_ttm_print_info() helper function
which adds some ttm specific lines to the debug output.

Sphinx need to know when a paragraph ends. So, do some adjustments
at the file for it to be properly parsed.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
that's said, I believe that this file should be moved to the
GPU/DRM documentation.

Add a modesetting driver for Grain Media GM12U320 based devices
(primarily Acer C120 projector, but there may be compatible devices).
This is based on the fb driver from Viacheslav Nurmekhamitov:
https://github.com/slavrn/gm12u320
This driver uses drm_simple_display_pipe to deal with all the atomic
stuff, gem_shmem_helper functions for buffer management and
drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver
itself with only the actual code for talking to the gm12u320 chip,
leading to a nice simple and clean driver.
Changes in v2:
-Add drm-misc tree to MAINTAINERS
-Drop mode_config.preferred_depth = 24 / fix fbdev support

Add a KMS driver for the Ingenic JZ47xx family of SoCs.
This driver is meant to replace the aging jz4740-fb driver.
This driver does not make use of the simple pipe helper, for the reason
that it will soon be updated to support more advanced features like
multiple planes, IPU integration for colorspace conversion and up/down
scaling, support for DSI displays, and TV-out and HDMI outputs.
Notes:
v2: - Remove custom handling of panel. The panel is now discovered using
the standard API.
- Lots of small tweaks suggested by upstream
v3: - Use devm_drm_dev_init()
- Update compatible strings to -lcd instead of -drm
- Add destroy() callbacks to plane and crtc
- The ingenic,lcd-mode is now read from the bridge's DT node
v4: Remove ingenic,lcd-mode property completely. The various modes are now
deduced from the connector type, the pixel format or the bus flags.
v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers
- Use 32bpp framebuffer instead of 16bpp, as it'll work with both
16-bit and 24-bit panel
- Get rid of drm_format_plane_cpp() which has been dropped upstream
- Avoid using drm_format_info->depth, which is deprecated.

This adds a new DRM driver for the ST-Ericsson Multi Channel
Display Engine, MCDE display controller.
This hardware has three independent DSI hosts and can composit
and display several memory buffers onto an LCD display. It
was developed for several years inside of ST-Ericsson and
shipped with a few million mobile phones from Sony and Samsung,
as well as with the Snowball community development board.
The driver is currently pretty rudimentary but supports a
simple framebuffer so we can get penguins and graphics when
using these SoCs.

The type |struct drm_gem_vram_object| implements a GEM object for simple
framebuffer devices with dedicated video memory. The BO is either located
in VRAM or system memory.
The implementation has been created from the respective code in ast,
bochs and mgag200. These drivers copy their implementation from each
other; except for the names of several data types. The helpers are
currently build with TTM, but this is considered an implementation
detail and may change in future updates.
v5:
* do WARN_ON_ONCE for pin-count mismatches
* allocate only 2 entries in placements array
v4:
* cleanups from checkpatch.pl
* removed several fixed-size types from interfaces
* DRM_VRAM_HELPER now selects DRM_TTM
* remove separate config option for GEM VRAM
v2:
* rename to |struct drm_gem_vram_object|
* move drm_is_gem_ttm() to a later patch in the series
* add drm_gem_vram_kmap_at()
* return is_iomem from kmap functions
* redefine TTM placement flags for public interface
* documentation fixes

- Mali 4xx GPUs have two kinds of processors GP and PP. GP is for
OpenGL vertex shader processing and PP is for fragment shader
processing. Each processor has its own MMU so prcessors work in
virtual address space.
- There's only one GP but multiple PP (max 4 for mali 400 and 8
for mali 450) in the same mali 4xx GPU. All PPs are grouped
togather to handle a single fragment shader task divided by
FB output tiled pixels. Mali 400 user space driver is
responsible for assign target tiled pixels to each PP, but mali
450 has a HW module called DLBU to dynamically balance each
PP's load.
- User space driver allocate buffer object and map into GPU
virtual address space, upload command stream and draw data with
CPU mmap of the buffer object, then submit task to GP/PP with
a register frame indicating where is the command stream and misc
settings.
- There's no command stream validation/relocation due to each user
process has its own GPU virtual address space. GP/PP's MMU switch
virtual address space before running two tasks from different
user process. Error or evil user space code just get MMU fault
or GP/PP error IRQ, then the HW/SW will be recovered.
- Use GEM+shmem for MM. Currently just alloc and pin memory when
gem object creation. GPU vm map of the buffer is also done in
the alloc stage in kernel space. We may delay the memory
allocation and real GPU vm map to command submission stage in the
furture as improvement.
- Use drm_sched for GPU task schedule. Each OpenGL context should
have a lima context object in the kernel to distinguish tasks
from different user. drm_sched gets task from each lima context
in a fair way.
mesa driver can be found here before upstreamed:
