drm/fb-helper: Initialize fb-helper's preferred BPP in prepare function
Initialize the fb-helper's preferred_bpp field early from within
drm_fb_helper_prepare(); instead of the later client hot-plugging
callback. This simplifies the generic fbdev setup function.
No real changes, but all drivers' fbdev code has to be adapted.
v3:
* build with CONFIG_DRM_FBDEV_EMULATION unset (kernel test bot)
drm/fbdev-generic: Initialize fb-helper structure in generic setup
Initialize the fb-helper structure immediately after its allocation
in drm_fbdev_generic_setup(). That will make it easier to fill it with
driver-specific values, such as the preferred BPP.
Signal failed hotplugging with a flag in struct drm_client_dev. If set,
the client helpers will not further try to set up the fbdev display.
This used to be signalled with a combination of cleared pointers in
struct drm_fb_helper, which prevents us from initializing these pointers
early after allocation.
The change also harmonizes behavior among DRM clients. Additional DRM
clients will now handle failed hotplugging like fbdev does.
drm/client: Test for connectors before sending hotplug event
Test for connectors in the client code and remove a similar test
from the generic fbdev emulation. Do nothing if the test fails.
Not having connectors indicates a driver bug.

drm/nouveau/devinit: Convert function disable() to be void
The current design of callback function disable() of struct
nvkm_devinit_func is defined to return a u64 value. In its implementation
in the driver modules, the function always returns a fixed value 0. Hence
the design and implementation of this function should be enhanced to return
void instead of a fixed value. This change also eliminates untouched
return variables.

drm/edid: add separate drm_edid_connector_add_modes()
The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.
Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.
Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().
Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:
1) drm_edid_connector_update() must be called before
drm_edid_connector_add_modes().
Display info and quirks are needed for parsing the modes, and we
don't want to call update_display_info() again to ensure the info is
available, like drm_add_edid_modes() does.
2) The same EDID is used for both updating the connector and adding the
probed modes.
Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

Separate the parsing of display info and modes from the HDMI VSDB. This

The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").

Each of the user contexts has two command queues, one for compute engine
and one for the copy engine. Command queues are allocated and registered
in the device when the first job (command buffer) is submitted from
the user space to the VPU device. The userspace provides a list of
GEM buffer object handles to submit to the VPU, the driver resolves
buffer handles, pins physical memory if needed, increments ref count
for each buffer and stores pointers to buffer objects in
the ivpu_job objects that track jobs submitted to the device.
The VPU signals job completion with an asynchronous message that
contains the job id passed to firmware when the job was submitted.
Currently, the driver supports simple scheduling logic
where jobs submitted from user space are immediately pushed
to the VPU device command queues. In the future, it will be
extended to use hardware base scheduling and/or drm_sched.

Adds four types of GEM-based BOs for the VPU:
- shmem
- internal
- prime
All types are implemented as struct ivpu_bo, based on
struct drm_gem_object. VPU address is allocated when buffer is created
except for imported prime buffers that allocate it in BO_INFO IOCTL due
to missing file_priv arg in gem_prime_import callback.
Internal buffers are pinned on creation, the rest of buffers types
can be pinned on demand (in SUBMIT IOCTL).
Buffer VPU address, allocated pages and mappings are released when the
buffer is destroyed.
Eviction mechanism is planned for future versions.
VPU Memory Management Unit is based on ARM MMU-600.
It allows the creation of multiple virtual address spaces for
the device and map noncontinuous host memory (there is no dedicated
memory on the VPU).
Address space is implemented as a struct ivpu_mmu_context, it has an ID,
drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that
holds actual 3-level, 4KB page table.
Context with ID 0 (global context) is created upon driver initialization
and it's mainly used for mapping memory required to execute
the firmware.
Contexts with non-zero IDs are user contexts allocated each time
the devices is open()-ed and they map command buffers and other
workload-related memory.
Workloads executing in a given contexts have access only
to the memory mapped in this context.
This patch is has two main files:
- ivpu_mmu_context.c handles MMU page tables and memory mapping
- ivpu_mmu.c implements a driver that programs the MMU device

- Buttress - provides CPU to VPU integration, interrupt, frequency and
power management.
- Memory Management Unit (based on ARM MMU-600) - translates VPU to
host DMA addresses, isolates user workloads.
- RISC based microcontroller - executes firmware that provides job
execution API for the kernel-mode driver
- Neural Compute Subsystem (NCS) - does the actual work, provides
Compute and Copy engines.
- Network on Chip (NoC) - network fabric connecting all the components
This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).
Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".
This patch includes only very besic functionality:
- module, PCI device and IRQ initialization
- register definitions and low level register manipulation functions
- SET/GET_PARAM ioctls
- power up without firmware

display info, and replace it with a local variable.
This is prerequisite work for overall better separation of the two
parsing steps (updating display info and adding modes).

drm/edid: use VIC in AVI infoframe if sink lists it in CTA VDB
Apparently there are HDMI 1.4 compatible displays out there that support
VICs from specs later than CTA-861-D, i.e. VIC > 64, although HDMI 1.4
references CTA-861-D only.
We try to avoid using VICs from the later specs in the AVI infoframes to
avoid upsetting sinks that conform to earlier specs.
However, it seems reasonable to do this when the sink claims it supports
the VIC. With the pre-parsed list of VICs handy, this is now trivial.

drm/edid: Use the pre-parsed VICs
Now that we have all the VICs in info->vics, use them to simplify access
based on VIC index, i.e. on the order of VICs in the EDID, and avoid
passing CTA VDB pointers around.
This also fixes the highly unlikely scenarios of a) multiple HDMI VSDBs,
and b) HDMI VSDB 3D modes using VIC indexes that span across multiple
CTA VDBs, and the combination of the two.

drm/edid: parse VICs from CTA VDB early
A number of places need access to the VICs. Just parse them early for
easy access. Gracefully handle multiple CTA VDBs. It's unlikely to have
more than one, but the CTA-861 references "Video Data Block(s)", so err
on the safe side.
Start parsing them now, convert users in follow-up to have fewer moving
parts in one go.

drm/edid: fix parsing of 3D modes from HDMI VSDB
Commit 537d9ed2f6c1 ("drm/edid: convert add_cea_modes() to use cea db
iter") inadvertently moved the do_hdmi_vsdb_modes() call within the db
iteration loop, always passing NULL as the CTA VDB to
do_hdmi_vsdb_modes(), skipping a lot of stereo modes.
Move the call back outside of the loop.
This does mean only one CTA VDB and HDMI VSDB combination will be
handled, but it's an unlikely scenario to have more than one of either
block, and it was not accounted for before the regression either.

drm/edid: fix AVI infoframe aspect ratio handling
We try to avoid sending VICs defined in the later specs in AVI
infoframes to sinks that conform to the earlier specs, to not upset
them, and use 0 for the VIC instead. However, we do this detection and
conversion to 0 too early, as we'll need the actual VIC to figure out
the aspect ratio.
In particular, for a mode with 64:27 aspect ratio, 0 for VIC fails the
AVI infoframe generation altogether with -EINVAL.
Separate the VIC lookup from the "filtering", and postpone the
filtering, to use the proper VIC for aspect ratio handling, and the 0
VIC for the infoframe video code as needed.
