This set of patches enables the new DAL display driver for amdgpu on Carrizo
Tonga, and Fiji ASICs. This driver will allow us going forward to bring
display features on the open amdgpu driver (mostly) on par with the Catalyst
driver.
This driver adds support for
- Atomic KMS API
- MST
- HDMI 2.0
- Better powerplay integration
- Support of HW bandwidth formula on Carrizo
- Better multi-display support and handling of co-functionality
- Broader support of display dongles
- Timing synchronization between DP and HDMI
This patch series is based on Alex Deucher's drm-next-4.6-wip tree.

Laying the groundwork for the AMD DAL display driver.
This patch includes the basic services and defines basic
types required by the display driver, such as:
- ASIC register access
- VBIOS access
- Vector and flat_set data structures
- Display signal types
- ASIC versions and IDs
- HW IDs
- Logging functionality
This patch adds Kconfig options to enable the DAL
display driver.
- DRM_AMD_DAL
- DRM_AMD_DAL_VBIOS_PRESENT
- DRM_AMD_DAL_DCE11_0
- DRM_AMD_DAL_DCE10_0
- DEBUG_KERNEL_DAL

Adds dce110_resource and dce110_hw_sequencer files.
dce110_resource manages creation of HW resources, along with correct
ASIC register offset for each block.
dce110_hw_sequencers is responsible for programming HW sequences,
such as enable_stream, program_scaler, power_down_encoders, etc.

To: dri-devel
Adds a logical representation of our hardware. Provides ability to
- dc_validate_resources - validate a display configuration
- dc_commit_targets - commit a display configuration
- dc_commit_surfaces_to_target - update surfaces
- dc_link_detect - detect displays at link
- dc_resume - resume display HW
- dc_interrupt_set/ack - set and ack interrupts
- etc.

Hi
Does that mean Tonga is capable of HDMI 2.0 or is it only Carrizo
Cheers

This set of patches enables the new DAL display driver for amdgpu on Carrizo
Tonga, and Fiji ASICs. This driver will allow us going forward to bring
display features on the open amdgpu driver (mostly) on par with the Catalyst
driver.
This driver adds support for
- Atomic KMS API
- MST
- HDMI 2.0
- Better powerplay integration
- Support of HW bandwidth formula on Carrizo
- Better multi-display support and handling of co-functionality
- Broader support of display dongles
- Timing synchronization between DP and HDMI
This patch series is based on Alex Deucher's drm-next-4.6-wip tree.

so without actually looking too closely at this rather large patch (in
a rather huge patchset).. I do wonder, why not i2c_adapter? Kernel
already has an implementation of that on top of gpio's..

So the first minor criticism is this patch doesn't explain WHY.
Why does the Linux kernel need 93k lines of code to run the displays
when whole drivers don't even come close.
We've spent a lot of time ripping abstraction layers out of drivers (exynos
being the major one), what benefits does this major change bring to the
Linux kernel and the AMDGPU driver over and above a leaner, more focused
work.
If were even to consider merging this it would be at a guess considered
staging level material which would require a TODO list of major cleanups.
I do realise you've put a lot of work into this, but I think you are going to
get a lot of review pushback in the next few days and without knowing the
reasons this path was chosen it is going to be hard to take.
Dave.

Later down there also seems to be a reinvention of i2c over dp aux or
something similar ...

One minor suggestion for the V2 of this patch-set, please squash
patches 27-29 into the previous patches (relevant to the code they
change). No point in reviewing code of earlier patches that is later
going to be changed by a patch in the same patch-set.
Thanks,
Oded

Yeah agreed, we need to figure out the why/how first. Assembling a
de-staging TODO is imo a second step. And the problem with that is
that before we can do a full TODO we need to remove all the os and drm
abstractions. I found delayed_work, timer, memory handling, pixel
formats (in multiple copies), the i2c stuff Rob noticed and there's
more I'm sure. With all that I just can't even see how the main DAL
structures connect and how that would sensibly map to drm concepts.
Which is most likely needed to make DAL properly atomic.
So de-staging DAL (if we decided this is the right approach) would be
multi-stage, with removal of the abstractions not needed first, then
taking a 2nd look and figuring out how to untangle the actual
concepts.
Aside: If all this abstraction is to make dal run in userspace for
testing or whatever - nouveau does this, we (Intel) want to do this
too for unit-testing, so there's definitely room for sharing the
tools. But the right approach imo is to just implement kernel services
(like timers) in userspace.
Another thing is that some of the features in here (hdmi 2.0, improved
dongle support) really should be in shared helpers. If we have that
hidden behind the dal abstraction it'll be pretty much impossible
(with major work, which is unreasonable to ask of other people trying
to get their own driver in) to extract&share it. And for sink handling
having multiple copies of the same code just doesn't make sense.
Anyway that's my quick thoughts from 2h of reading this. One wishlist:
Some design overview or diagram how dal structures connect would be
awesome as a reading aid.

Is this global, what about multiple GPUs in one machine,
is this per GPU or per system?

Yes some overview of what the abstractions are and why they exist,
Follow things down the layers really makes for hard work, and in a lot of
places for not much benefit.

More stuff plain duplicated I spotted:
- some edid handling (probably because of the duplicated i2c, but probably
also because dal).
- has it's own infoframe encoding it seems
- home-grown logging. Yes, DRM_DEBUG isn't the most awesome, but dynamic
prinkt is pretty neat from what I understand and we should just move
DRM_DEBUG over to that if you need more flexibility.

Hi Dave,
There should be one instance of amdgpu per GPU, so one instance of DAL per GPU, hence this should be per GPU.
We haven't really done any multi-GPU testing with this code, though, but I briefly tried and can light up with two displays connected to a Tonga and Bonaire (Bonaire is supported on our internal tree but hasn't been merged into these patches yet).

Is this global, what about multiple GPUs in one machine, is this per GPU or per system?

Hi Dave, Daniel, others,
The goal with DAL is to provide a unified, full featured display stack to service all of our Linux offerings. This driver will have to support our full feature set beyond what's supported by amdgpu, e.g.
- synchronzied timings across different displays
- freesync
- solid support of 6 displays in any configuration (HDMI, DVI, DP, DP MST, etc)
- solid support of 4k@60 timings on APUs
- power features, such as
- clock-accurate bandwidth formulas
- improved interaction with powerplay to maximize power savings
- Improved audio and other infoframe related features
- Improved stability with powerplay since display hw is involved in the SMC hw interactions and improper programming sequences can lead to GPU hangs, etc.
The current amdgpu display stack grew somewhat organically and as such is not well suited to handling all of the hardware dependencies involved especially in areas like audio. The drm abstractions used by the old code map less and less well to new hw pipelines. Atomic helps, but if we are going to convert, it seemed like a good time to start fresh.
Our DC (Display Core in dc.h, etc.) is the framework to allow us to well represent current and future HW architectures. These don't always map one-to-one to DRM interfaces. For one we can't make the assumption that surfaces map one-to-one to pipes.
The DAL internal abstractions were used since they match the abstractions used by our drivers for other OSes, pre and post silicon validation tools and HW team programming models. Keeping it as close to that as possible makes it easier to debug and validate and provides the most likely change of success in complex display configurations.
Please see the attached DC.png for an overview of the DAL design.
For an atomic sequence you might want to look at
- enable/disable displays or change display config -> dc_commit_targets
(in dc/core/dc.c, called from amdgpu_dm_atomic_commit in amdgpu_dm/amdgpu_dm_types.c)
- commit planes -> dc_commit_surfaces_to_targets
(in dc/core/dc_target.c, called from dm_dc_surface_commit in amdgpu_dm/amdgpu_dm_types.c)
- validate -> dc_validate_resources
(in dc/core/dc.c, called from amdgpu_dm_atomic_check in amdgpu_dm/amdgpu_dm_types.c)
There's still a bunch of legacy stuff in these patches that's on our list of things to refactor. Some of that is
- dc/adapter
- dc/asic_capability
- dc/audio
- dc/bios
- dc/gpio
We should be able to cut the size of this code to about 1/3 of what it is now.
As for the LOC we have about
22k for HW programming
30k legacy stuff
6k dc/calcs - autogenerated from formulas provided by HW team
15k includes
6k amdgpu_dm
8k dc/core
About 14k of those are blank lines (we have a habit of leaving lots of blank space) and 16k are comments.
Cheers,
Harry

Cleaning up that is not enough, abstracting kernel API like kmalloc or i2c,
or similar, is a no go. If the current drm infrastructure does not suit your
need then you need to work on improving it to suit your need. You can not
redevelop a whole drm layer inside your code and expect to upstream it.
Linux device driver are about sharing infrastructure and trying to expose
it through common API to userspace.
So i strongly suggest that you start thinking on how to change the drm API
to suit your need and to start discussions about those changes. If you need
them then they will likely be usefull to others down the road.
Cheers,
Jérôme

A bit more context on why OS abstractions layers like dal here are
massive frowned upon:
First reason is that it makes live painful for everyone who tries to
refactor across the entire subsystem (which I do a lot, so that's what
I care about). For that you need to be able to understand every driver
fairly quickly, and that's only possible if all drivers use the same
concepts. Which means no abstraction layer, but directly
using&extending core drm constructs like
drm_framebuffer/crtc/encoder/bridge/connector/display_information.
Even if your dal concepts match 1:1 with those, if the link is only at
runtime or through pointers instead of through subclassing everything
becomes much more painful to understand. Note that this isn't a reason
against hw/driver specific additional concepts (all big drivers have
those), but against undue amounts of insolation between drm concepts
and driver concepts.
The other bit is the so-called midlayer design mistake,
https://lwn.net/Articles/336262/ which states that wedging an entire
such abstraction layer will also inevitably lead to bad design overall
(neglecting the practical troubles is causes for everyone else). DRM
suffered badly from the midlayer of old days due to compat with *bsd
in the core, which took years to fix up (and is still not completely
done). And we only ever merged 2 drivers who had midlayers like dal,
and both had special reasons:
- exynos was one of the very first armsoc kms drivers, and merged
pretty much for goodwill. Google was eventually fed up with the
midlayer in upstream and paid Collabora to nuke it.
- omapdrm reused the display support code already merged into upstream
in the fbdev subsytem, and that's why it had a midlayer. But Tomi is
now also in the process of removing this.
So even if all the cleanup is done (removal of duplicated code and the
OS abstraction layers) there's some really big reservations against
DAL as a concept itself. That was essentially what's Dave "why do we
need this" was all about. And to answer that you need in my opinion
better reasons "shared abstraction with $otheros/thing/whatever",
since if that's the only reason you argue against 20+ years of shared
experience in linux device driver development that this is a very bad
one.
Note again that this isn't against introducing additional
amd-speicific display concepts in the amd driver, or existing
concepts. Every driver does that. This is just against putting an
entire abstraction layer in-between drm core and your real display
driver.
The other big issue is that upstream really puts a lot of weight onto
continuity - no forking or wholesale rewrites every 1-2 years, instead
gradual change of what's already there. And I suspect the amount of
effort to get dal into a reasonable shape is on par with just adding
the new features you want to amdgpu directly one-by-one. Starting out
with amdgpu also has the added benefit that there's lots of howtos
and experience with converting an existing kms driver to atomic. We
don't really have that for DAL->atomic, and from reading through the
code I couldn't convince myself that the current code is really
atomic. Largely that's due to not using drm core concepts and
structures, but remapping things.
Anyway, I figured I type in a few more words to explain some of the
reasons behind the resistance to massive abstraction layers in kernel
device drivers.
Cheers, Daniel

So, this sounds a bit vaguely like some things that I have discussed
from drm/msm.. where you might end up using multiple planes to scan
out a single surface, or multiplex a single plane between multiple
surfaces (or combinations thereof)..
I think what we'll end up doing is virtualizing planes so we advertise
to userspace more planes than actually exist, and at atomic update
time, dynamically assign pipes to planes, and reject things if
userspace asks for too many planes.. although this is getting into an
area where it helps to assume that there is a userspace component
which is familiar with your hw, which is true for android (and I think
some day wayland compositors will have to grow similar capability for
driver specific userspace plugin to make decisions about how to assign
planes).
Not sure if a similar approach would help you to fit better into the
kms/atomic framework?

Hm, maybe I misread the code and the diagram, but to me it looked like
dc_surface == drm_plane. And you can already freely assign drm_planes
to display pipelines (represented by drm_crtc). That's btw also the
part where your atomic driver seems to seriously mismatch how drm
atomic is meant to be used, since you dig out the connector state when
commit plane states, which is a no-go.
dc_target otoh seems to not entirely match to drm_crtc, and contain
some of drm_display_info and drm_connector stuff too. At least from
cursory reading around in the code.
So not sure how this should all map, but like Rob said you can
internally virtualize stuff if really needed. But then you should
still pass around drm_plane_state in your low-level hw commit
functions and not dal-private structures to avoid the midlayer issues.

top-level post since I can't reply to the diagram directly. So from
very cursor reading-around in the code I think you have a few
mismatches in how you map drm concepts to dal structures:
- cursor is just a drm_plane - step 0 of atomic support is universale
plane support, and you didn't do that in this patch series. Same holds
for video overlay support (which seems implemented but not exposed).
- drm_plane should probably match to both surface + target structs,
since how a plane is composited in the screen rect is a plane state
- stream should probably map to crtc
- for cases where you need 2 streams for 1 crtc or 2 surfaces for 1
plane internally remap them with some aux pointer. But imo still base
them on drm core structures (since in most cases you can expose them
all). You probably need a full remapping table to make this work, but
the state itself should still all be in extensions of core drm_*_state
structs
- drm_encoder probably matches to dc_link, but not sure. drm_encoder
is mostly just a convenience thing really, you can ignore it
- dc_sink seems to be the drm_connector, or well mostly. Here it gets
really unclear due to the massive amount of private code for
screen/sink handling that dal has.

Keeping it as close to that as possible makes it easier to debug and validate and provides the most likely change of success in complex display configurations.

As a very high-level comment, my worry is that you feel like DRM
doesn't supoort this so are inventing it in the DAL. This is
understandable, but the problem is that DRM will come up with a
different interface for things like genlock or FreeSync; one that is
unlikely to match the abstraction in the DAL.
If there are areas you feel core DRM does not address but need to be
supported, please start by working in the core and building out from
there.
Cheers,
Daniel

For sure. Thanks, Oded.
I'll send out squashed patches later today.

v2 Update:
This is just a squash of the three small fixes into the main patches to
make for an easier read. No other changes yet.
This set of patches enables the new DAL display driver for amdgpu on Carrizo
Tonga, and Fiji ASICs. This driver will allow us going forward to bring
display features on the open amdgpu driver (mostly) on par with the Catalyst
driver.
This driver adds support for
- Atomic KMS API
- MST
- HDMI 2.0
- Better powerplay integration
- Support of HW bandwidth formula on Carrizo
- Better multi-display support and handling of co-functionality
- Broader support of display dongles
- Timing synchronization between DP and HDMI
This patch series is based on Alex Deucher's drm-next-4.6-wip tree.

Laying the groundwork for the AMD DAL display driver.
This patch includes the basic services and defines basic
types required by the display driver, such as:
- ASIC register access
- VBIOS access
- Vector and flat_set data structures
- Display signal types
- ASIC versions and IDs
- HW IDs
- Logging functionality
This patch adds Kconfig options to enable the DAL
display driver.
- DRM_AMD_DAL
- DRM_AMD_DAL_VBIOS_PRESENT
- DRM_AMD_DAL_DCE11_0
- DRM_AMD_DAL_DCE10_0
- DEBUG_KERNEL_DAL

Adds dce110_resource and dce110_hw_sequencer files.
dce110_resource manages creation of HW resources, along with correct
ASIC register offset for each block.
dce110_hw_sequencers is responsible for programming HW sequences,
such as enable_stream, program_scaler, power_down_encoders, etc.

To: dri-devel
Adds a logical representation of our hardware. Provides ability to
- dc_validate_resources - validate a display configuration
- dc_commit_targets - commit a display configuration
- dc_commit_surfaces_to_target - update surfaces
- dc_link_detect - detect displays at link
- dc_resume - resume display HW
- dc_interrupt_set/ack - set and ack interrupts
- etc.

Hi Rob,
that's a good point. We'll see if we can use DRM and existing amdgpu
code for i2c/aux and rip this one out.
Cheers,

Hi Rob,
thanks for the heads-up for this. We're definitely interested in
contributing to proposed new frameworks.
I'm not sure we want to tightly couple userspace with hardware, though.
Your proposal seems to assume that user mode is responsible for knowing
how many planes any given configuration needs, or iterating through
failures until a successful solution is found. First this is quite
sub-optimal and would be hard to get right without duplicating most of
kernel driver resource management in user mode. Second this doesn't
solve the problem with fbcon or other solutions when there is no
user-mode component.
Cheers,
Harry

Hi Jerome,
some of the kernel API is abstracted to allow testing of this driver in
user space for pre- and post-silicon validation. An alternative that
we've considered is implementing the kernel functions in user space.
That's definitely an option.
We're definitely open to push things into drm and help develop common
functionality, such as MST and others. The DC abstraction is necessary,
however, to handle current and future hardware requirements agnostically.
Cheers,
Harry

Hi Daniel,
we've considered making cursor a plane but haven't done so (yet) because
cursor is sort of a unique concept in our HW and doesn't map well to planes.
Will take the time to look at the other mappings a bit more closely.
Cheers,
Harry

Limitting v3 patches to only the modified patches, so as to reduce spam:
0001-drm-amd-dal-Add-dal-headers.patch
0005-drm-amd-dal-GPIO-General-Purpose-IO.patch
0007-drm-amd-dal-BIOS-Parser.patch
0024-drm-amd-dal-Add-display-core.patch
0025-drm-amd-dal-Adding-amdgpu_dm-for-dal.patch
0026-drm-amdgpu-Use-dal-driver-for-Carrizo-Tonga-and-Fiji.patch
Change History
--------------
v3:
- rebase on Alex's latest drm-next-4.6-wip
- export some functions to share with DAL
- use amdgpu's existing dce functions for some things, such as mc_access
- add stoney to dal check
- add missing hawaii and stoney case statements
- remove page work flip queue and use system queue instead
- minor dm_helpers function name cleanup
- expose I2C through i2c_adapter and route dal i2c calls through this
v2:
This is just a squash of the three small fixes into the main patches to
make for an easier read. No other changes yet.
Description
-----------
This set of patches enables the new DAL display driver for amdgpu on Carrizo
Tonga, and Fiji ASICs. This driver will allow us going forward to bring
display features on the open amdgpu driver (mostly) on par with the Catalyst
driver.
This driver adds support for
- Atomic KMS API
- MST
- HDMI 2.0
- Better powerplay integration
- Support of HW bandwidth formula on Carrizo
- Better multi-display support and handling of co-functionality
- Broader support of display dongles
- Timing synchronization between DP and HDMI
This patch series is based on Alex Deucher's drm-next-4.6-wip tree.

v3 changes:
- expose I2C through i2c_adapter and route dal i2c calls through this
Manages all DCE GPIO pins. The pins are represented as generic IO
handles as well as handles dedicated for certain functions, such as
DDC, HPD, and DVO.

From: Harry Wentland @ 2016-02-29 21:56 UTC (permalink / raw)
To: dri-devel
Adds a logical representation of our hardware. Provides ability to
- dc_validate_resources - validate a display configuration
- dc_commit_targets - commit a display configuration
- dc_commit_surfaces_to_target - update surfaces
- dc_link_detect - detect displays at link
- dc_resume - resume display HW
- dc_interrupt_set/ack - set and ack interrupts
- etc.
v3 changes:
- minor dm_helpers name cleanup
- expose I2C through i2c_adapter and route dal i2c calls through this

5 siblings, 0 replies; 87+ messages in thread
From: Harry Wentland @ 2016-02-29 21:56 UTC (permalink / raw)
To: dri-devel
Implements DRM's atomic KMS interfaces using DC.
v3 changes:
- use amdgpu's existing dce functions for some things, such as mc_access
- add stoney to dal check
- add missing hawaii and stoney case statements
- remove page work flip queue and use system queue instead
- minor dm_helpers function name cleanup
- expose I2C through i2c_adapter and route dal i2c calls through this

From: Harry Wentland @ 2016-02-29 21:56 UTC (permalink / raw)
To: dri-devel
Start to use dal by default on Carrizo, Tonga, and Fiji ASICs.
v3 changes:
- rebase on Alex's latest drm-next-4.6-wip
- export some functions to share with DAL
- remove has_dal_support macro and move logic into amdgpu_device_has_dal_support
