drm/msm/mdp5: Assign 'right' mixer to CRTC state
Dynamically assign a right mixer to mdp5_crtc_state in the CRTC's
atomic_check path. Assigning the right mixer has some constraints,
i.e, only a few LMs can be paired together. Update mdp5_mixer_assign
to handle these constraints.
Firstly, we need to identify whether we need a right mixer or not.
At the moment, there are 2 scenarios where a right mixer might be
needed:
- If any of the planes connected to this CRTC is too wide (i.e, is
comprised of 2 hwpipes).
- If the CRTC's mode itself is too wide (i.e, a 4K mode on HDMI).
We implement both these checks in the mdp5_crtc_atomic_check(), and
pass 'need_right_mixer' to mdp5_setup_pipeline.
If a CRTC is already assigned a single mixer, and a new atomic commit
brings in a drm_plane that needs 2 hwpipes, we can successfully commit
this mode without requiring a full modeset, provided that we still use
the previously assigned mixer as the left mixer. If such an assignment
isn't possible, we'd need to do a full modeset. This scenario has been
ignored for now.
The mixer assignment code is a bit messy, considering we have at most
4 LM instances in hardware. This can probably be re-visited later with
simplified logic.

We'll extend this logic to support 2 hwpipes per plane later.

drm/msm/mdp5: Add a CAP for Source Split
Some of the newer MDP5 versions support Source Split of SSPPs. It is a
feature that allows us to route the output of a hwpipe to 2 Layer
Mixers. This is required to achieve the following use cases:
- Dual DSI: For high res DSI panels (such as 2560x1600 etc), a single
DSI interface doesn't have the bandwidth to drive the required pixel
clock. We use 2 DSI interfaces to drive the left and right halves
of the panel (i.e, 1280x1600 each). The MDP5 pipeline here would look
like:
LM0 -- DSPP0 -- INTF1 -- DSI1
/
hwpipe--
\
LM1 -- DSPP1 -- INTF2 -- DSI2
A single hwpipe is used to scan out the left and right halves to DSI1
and DSI2 respectively. In order to do this, we need to configure the
2 Layer Mixers in Source Split mode.
- HDMI 4K: In order to support resolutions with width higher than the
max width supported by a hwpipe, we club 2 hwpipes together:
hwpipe1 --- LM0 -- DSPP0
- - \
- -- 3D Mux -- INTF0 -- HDMI
- - /
hwpipe2 --- LM1 -- DSPP1
hwpipe1 is staged on the 'left' Layer Mixer, and hwpipe2 is staged on
the 'right' Layer Mixer. An additional block called the '3D Mux' is
used to merge the output of the 2 DSPPs to a single interface.
In this use case, it is possible that a 4K surface is downscaled and
placed completely within one of the halves. In order to support such
scenarios (and keep the programming simple), Layer Mixers with Source
Split can be assigned 2 hw pipes per stage. While scanning out, the HW
takes care of fetching the pixels fom the correct pipe.
Add a MDP cap to tell whether the HW supports source split or not.
Add a MDP LM cap that tells whether a LM instance can operate in
source split mode (and generate the 'left' part of the display
output).

These entities, however, are currently statically assigned to drm_encoders
(i.e. mdp5_encoder). Since these aren't directly visible to the CRTC, we
assign them to the CRTC state in the encoder's atomic_check() op.
With this approach, we assign portions of CRTC state in two different
places: the layer mixer in CRTC's atomic_check(), and the INTF and CTL
pieces in the encoder's atomic_check() op.
We'd have more options here if the drm core maintained encoder state too,
but the current approach of clubbing everything in CRTC's state works just
fine.
Unlike hwpipes and mixers, we don't need to keep a track of INTF/CTL
assignments in the global atomic state. This is because they're currently
not sharable resources. For example, INTF0 and CTL0 will always be assigned
to one drm_encoder. This can change later when we implement writeback and
want a CRTC to use a CTL for a while, and then release it for others to use
it. Or, when a drm_encoder can switch between using a single INTF vs

drm/msm: move submit fence wait out of struct_mutex
Probably a symptom of needing finer grained locking, but if we wait on
the incoming fence-fd (which could come from a different context) while
holding struct_mutex, that blocks retire_worker so gpu fences cannot get
signalled.
This causes a problem if userspace manages to get more than a frame
ahead, leaving the atomic-commit worker blocked waiting on fences that
cannot be signaled because submit is blocked waiting for a fence
signalled from vblank (after the atomic commit which is blocked).
If we start having multiple fence ctxs for the gpu, submit_fence_sync()
would probably need to move outside of struct_mutex as well.

Having access to the secboot instance loading a LS firmware can be

Change the secboot and msgqueue interfaces to take a mask of falcons to

FECS and GPCCS to be booted in a single firmware command.
For firmwares that only support single falcon boot, it is trivial to
loop over the mask and boot each falcons individually.

drm/nouveau/imem/gk20a: Turn instmem lock into mutex
The gk20a implementation of instance memory uses vmap()/vunmap() to map
memory regions into the kernel's virtual address space. These functions
may sleep, so protecting them by a spin lock is not safe. This triggers
a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this
by using a mutex instead.
