TODO(brendanhiggins@google.com): for recent versions of Linux
|

(5.10-5.12, maybe earlier), there's a bug with gcov counters not being

flushed in UML. This translates to very low (<1%) reported coverage. This is

DisplayPort controllers provide a control channel to the sinks that
|
||||
are hooked up to them. This is the DP AUX bus. Over the DP AUX bus
|
||||
we can query properties about a sink and also configure it. In
|
||||
particular, DP sinks support DDC over DP AUX which allows tunneling
|
||||
a standard I2C DDC connection over the AUX channel.
|
||||
|
||||
To model this relationship, DP sinks should be placed as children
|
||||
of the DP controller under the "aux-bus" node.
|
||||
|
||||
At the moment, this binding only handles the eDP case. It is
|
||||
possible it will be extended in the future to handle the DP case.
|
||||
For DP, presumably a connector would be listed under the DP AUX
|
||||
bus instead of a panel.

Requirements
|
||||
------------
|
||||
|
||||
KMS drivers might need to add extra properties to support new features. Each
|
||||
new property introduced in a driver needs to meet a few requirements, in
|
||||
addition to the one mentioned above:
|
||||
|
||||
* It must be standardized, documenting:
|
||||
|
||||
* The full, exact, name string;
|
||||
* If the property is an enum, all the valid value name strings;
|
||||
* What values are accepted, and what these values mean;
|
||||
* What the property does and how it can be used;
|
||||
* How the property might interact with other, existing properties.
|
||||
|
||||
* It must provide a generic helper in the core code to register that
|
||||
property on the object it attaches to.
|
||||
|
||||
* Its content must be decoded by the core and provided in the object's
|
||||
associated state structure. That includes anything drivers might want
|
||||
to precompute, like struct drm_clip_rect for planes.
|
||||
|
||||
* Its initial state must match the behavior prior to the property
|
||||
introduction. This might be a fixed value matching what the hardware
|
||||
does, or it may be inherited from the state the firmware left the
|
||||
system in during boot.
|
||||
|
||||
* An IGT test must be submitted where reasonable.

|

* parallel submission.
|
||||
*
|
||||
* Setup a slot in the context engine map to allow multiple BBs to be submitted
|
||||
* in a single execbuf IOCTL. Those BBs will then be scheduled to run on the GPU
|
||||
* in parallel. Multiple hardware contexts are created internally in the i915
|
||||
* run these BBs. Once a slot is configured for N BBs only N BBs can be
|
||||
* submitted in each execbuf IOCTL and this is implicit behavior e.g. The user
|
||||
* doesn't tell the execbuf IOCTL there are N BBs, the execbuf IOCTL knows how
|
||||
* many BBs there are based on the slot's configuration. The N BBs are the last
|
||||
* N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
|
||||
*
|
||||
* The default placement behavior is to create implicit bonds between each
|
||||
* context if each context maps to more than 1 physical engine (e.g. context is
|
||||
* a virtual engine). Also we only allow contexts of same engine class and these
|
||||
* contexts must be in logically contiguous order. Examples of the placement
|
||||
* behavior described below. Lastly, the default is to not allow BBs to
|
||||
* preempted mid BB rather insert coordinated preemption on all hardware
|
||||
* contexts between each set of BBs. Flags may be added in the future to change
|
||||
* both of these default behaviors.
|
||||
*
|
||||
* Returns -EINVAL if hardware context placement configuration is invalid or if
|
||||
* the placement configuration isn't supported on the platform / submission
|

I915 GuC Submission/DRM Scheduler Section
|
||||
=========================================
|
||||
|
||||
Upstream plan
|
||||
=============
|
||||
For upstream the overall plan for landing GuC submission and integrating the
|
||||
i915 with the DRM scheduler is:
|
||||
|
||||
* Merge basic GuC submission
|
||||
* Basic submission support for all gen11+ platforms
|
||||
* Not enabled by default on any current platforms but can be enabled via
|
||||
modparam enable_guc
|
||||
* Lots of rework will need to be done to integrate with DRM scheduler so
|
||||
no need to nit pick everything in the code, it just should be
|
||||
functional, no major coding style / layering errors, and not regress
|
||||
execlists
|
||||
* Update IGTs / selftests as needed to work with GuC submission
|
||||
* Enable CI on supported platforms for a baseline
|
||||
* Rework / get CI heathly for GuC submission in place as needed
|
||||
* Merge new parallel submission uAPI
|
||||
* Bonding uAPI completely incompatible with GuC submission, plus it has
|
||||
severe design issues in general, which is why we want to retire it no
|
||||
matter what
|
||||
* New uAPI adds I915_CONTEXT_ENGINES_EXT_PARALLEL context setup step
|
||||
which configures a slot with N contexts
|
||||
* After I915_CONTEXT_ENGINES_EXT_PARALLEL a user can submit N batches to
|
||||
a slot in a single execbuf IOCTL and the batches run on the GPU in
|
||||
paralllel
|
||||
* Initially only for GuC submission but execlists can be supported if
|
||||
needed
|
||||
* Convert the i915 to use the DRM scheduler
|
||||
* GuC submission backend fully integrated with DRM scheduler
|
||||
* All request queues removed from backend (e.g. all backpressure
|
||||
handled in DRM scheduler)
|
||||
* Resets / cancels hook in DRM scheduler
|
||||
* Watchdog hooks into DRM scheduler
|
||||
* Lots of complexity of the GuC backend can be pulled out once
|
||||
integrated with DRM scheduler (e.g. state machine gets
|
||||
simplier, locking gets simplier, etc...)
|
||||
* Execlists backend will minimum required to hook in the DRM scheduler
|
||||
* Legacy interface
|
||||
* Features like timeslicing / preemption / virtual engines would
|
||||
be difficult to integrate with the DRM scheduler and these
|
||||
features are not required for GuC submission as the GuC does
|
||||
these things for us
|
||||
* ROI low on fully integrating into DRM scheduler
|
||||
* Fully integrating would add lots of complexity to DRM
|
||||
scheduler
|
||||
* Port i915 priority inheritance / boosting feature in DRM scheduler
|
||||
* Used for i915 page flip, may be useful to other DRM drivers as
|
||||
well
|
||||
* Will be an optional feature in the DRM scheduler
|
||||
* Remove in-order completion assumptions from DRM scheduler
|
||||
* Even when using the DRM scheduler the backends will handle
|
||||
preemption, timeslicing, etc... so it is possible for jobs to
|
||||
finish out of order
|
||||
* Pull out i915 priority levels and use DRM priority levels
|
||||
* Optimize DRM scheduler as needed
|
||||
|
||||
TODOs for GuC submission upstream
|
||||
=================================
|
||||
|
||||
* Need an update to GuC firmware / i915 to enable error state capture
|
||||
* Open source tool to decode GuC logs
|
||||
* Public GuC spec
|
||||
|
||||
New uAPI for basic GuC submission
|
||||
=================================
|
||||
No major changes are required to the uAPI for basic GuC submission. The only
|
||||
change is a new scheduler attribute: I915_SCHEDULER_CAP_STATIC_PRIORITY_MAP.
|
||||
This attribute indicates the 2k i915 user priority levels are statically mapped
|
||||
into 3 levels as follows:
|
||||
|
||||
* -1k to -1 Low priority
|
||||
* 0 Medium priority
|
||||
* 1 to 1k High priority
|
||||
|
||||
This is needed because the GuC only has 4 priority bands. The highest priority
|
||||
band is reserved with the kernel. This aligns with the DRM scheduler priority
|
||||
levels too.

||||

||||

|
||||
New parallel submission uAPI
|
||||
============================
|
||||
The existing bonding uAPI is completely broken with GuC submission because
|
||||
whether a submission is a single context submit or parallel submit isn't known
|
||||
until execbuf time activated via the I915_SUBMIT_FENCE. To submit multiple
|
||||
contexts in parallel with the GuC the context must be explicitly registered with
|
||||
N contexts and all N contexts must be submitted in a single command to the GuC.
|
||||
The GuC interfaces do not support dynamically changing between N contexts as the
|
||||
bonding uAPI does. Hence the need for a new parallel submission interface. Also
|
||||
the legacy bonding uAPI is quite confusing and not intuitive at all. Furthermore
|
||||
I915_SUBMIT_FENCE is by design a future fence, so not really something we should
|
||||
continue to support.
|
||||
|
||||
The new parallel submission uAPI consists of 3 parts:
|
||||
|
||||
* Export engines logical mapping
|
||||
* A 'set_parallel' extension to configure contexts for parallel
|
||||
submission
|
||||
* Extend execbuf2 IOCTL to support submitting N BBs in a single IOCTL
|
||||
|
||||
Export engines logical mapping
|
||||
------------------------------
|
||||
Certain use cases require BBs to be placed on engine instances in logical order
|
||||
(e.g. split-frame on gen11+). The logical mapping of engine instances can change
|
||||
based on fusing. Rather than making UMDs be aware of fusing, simply expose the
|
||||
logical mapping with the existing query engine info IOCTL. Also the GuC
|
||||
submission interface currently only supports submitting multiple contexts to
|
||||
engines in logical order which is a new requirement compared to execlists.
|
||||
Lastly, all current platforms have at most 2 engine instances and the logical
|
||||
order is the same as uAPI order. This will change on platforms with more than 2
|
||||
engine instances.
|
||||
|
||||
A single bit will be added to drm_i915_engine_info.flags indicating that the
|
||||
logical instance has been returned and a new field,
|
||||
drm_i915_engine_info.logical_instance, returns the logical instance.
|
||||
|
||||
A 'set_parallel' extension to configure contexts for parallel submission
|
||||
------------------------------------------------------------------------
|
||||
The 'set_parallel' extension configures a slot for parallel submission of N BBs.
|
||||
It is a setup step that must be called before using any of the contexts. See
|
||||
I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE or I915_CONTEXT_ENGINES_EXT_BOND for
|
||||
similar existing examples. Once a slot is configured for parallel submission the
|
||||
execbuf2 IOCTL can be called submitting N BBs in a single IOCTL. Initially only
|
||||
supports GuC submission. Execlists supports can be added later if needed.
|
||||
|
||||
Add I915_CONTEXT_ENGINES_EXT_PARALLEL_SUBMIT and
|
||||
drm_i915_context_engines_parallel_submit to the uAPI to implement this
|
||||
extension.

|
||||
|
||||
Extend execbuf2 IOCTL to support submitting N BBs in a single IOCTL
|
||||
-------------------------------------------------------------------
|
||||
Contexts that have been configured with the 'set_parallel' extension can only
|
||||
submit N BBs in a single execbuf2 IOCTL. The BBs are either the last N objects
|
||||
in the drm_i915_gem_exec_object2 list or the first N if I915_EXEC_BATCH_FIRST is
|
||||
set. The number of BBs is implicit based on the slot submitted and how it has
|
||||
been configured by 'set_parallel' or other extensions. No uAPI changes are
|
||||
required to the execbuf2 IOCTL.

Linux Kernel TIPC
|
||||
=================
|
||||
|
||||
TIPC (Transparent Inter Process Communication) is a protocol that is
|
||||
specially designed for intra-cluster communication.
|
||||
Introduction
|
||||
============
|
||||
|
||||
For more information about TIPC, see http://tipc.sourceforge.net.
|
||||
TIPC (Transparent Inter Process Communication) is a protocol that is specially
|
||||
designed for intra-cluster communication. It can be configured to transmit
|
||||
messages either on UDP or directly across Ethernet. Message delivery is
|
||||
sequence guaranteed, loss free and flow controlled. Latency times are shorter
|
||||
than with any other known protocol, while maximal throughput is comparable to
|
||||
that of TCP.
|
||||
|
||||
TIPC Features
|
||||
-------------
|
||||
|
||||
- Cluster wide IPC service
|
||||
|
||||
Have you ever wished you had the convenience of Unix Domain Sockets even when
|
||||
transmitting data between cluster nodes? Where you yourself determine the
|
||||
addresses you want to bind to and use? Where you don't have to perform DNS
|
||||
lookups and worry about IP addresses? Where you don't have to start timers
|
||||
to monitor the continuous existence of peer sockets? And yet without the
|
||||
downsides of that socket type, such as the risk of lingering inodes?
|
||||
|
||||
Welcome to the Transparent Inter Process Communication service, TIPC in short,
|
||||
which gives you all of this, and a lot more.
|
||||
|
||||
- Service Addressing
|
||||
|
||||
A fundamental concept in TIPC is that of Service Addressing which makes it
|
||||
possible for a programmer to chose his own address, bind it to a server
|
||||
socket and let client programs use only that address for sending messages.
|
||||
|
||||
- Service Tracking
|
||||
|
||||
A client wanting to wait for the availability of a server, uses the Service
|
||||
Tracking mechanism to subscribe for binding and unbinding/close events for
|
||||
sockets with the associated service address.
|
||||
|
||||
The service tracking mechanism can also be used for Cluster Topology Tracking,
|
||||
i.e., subscribing for availability/non-availability of cluster nodes.
|
||||
|
||||
Likewise, the service tracking mechanism can be used for Cluster Connectivity
|
||||
Tracking, i.e., subscribing for up/down events for individual links between
|
||||
cluster nodes.
|
||||
|
||||
- Transmission Modes
|
||||
|
||||
Using a service address, a client can send datagram messages to a server socket.
|
||||
|
||||
Using the same address type, it can establish a connection towards an accepting
|
||||
server socket.
|
||||
|
||||
It can also use a service address to create and join a Communication Group,
|
||||
which is the TIPC manifestation of a brokerless message bus.
|
||||
|
||||
Multicast with very good performance and scalability is available both in
|
||||
datagram mode and in communication group mode.
|
||||
|
||||
- Inter Node Links
|
||||
|
||||
Communication between any two nodes in a cluster is maintained by one or two
|
||||
Inter Node Links, which both guarantee data traffic integrity and monitor
|
||||
the peer node's availability.
|
||||
|
||||
- Cluster Scalability
|
||||
|
||||
By applying the Overlapping Ring Monitoring algorithm on the inter node links
|
||||
it is possible to scale TIPC clusters up to 1000 nodes with a maintained
|
||||
neighbor failure discovery time of 1-2 seconds. For smaller clusters this
|
||||
time can be made much shorter.
|
||||
|
||||
- Neighbor Discovery
|
||||
|
||||
Neighbor Node Discovery in the cluster is done by Ethernet broadcast or UDP
|
||||
multicast, when any of those services are available. If not, configured peer
|
||||
IP addresses can be used.
|
||||
|
||||
- Configuration
|
||||
|
||||
When running TIPC in single node mode no configuration whatsoever is needed.
|
||||
When running in cluster mode TIPC must as a minimum be given a node address
|
||||
(before Linux 4.17) and told which interface to attach to. The "tipc"
|
||||
configuration tool makes is possible to add and maintain many more
|
||||
configuration parameters.
|
||||
|
||||
- Performance
|
||||
|
||||
TIPC message transfer latency times are better than in any other known protocol.
|
||||
Maximal byte throughput for inter-node connections is still somewhat lower than
|
||||
for TCP, while they are superior for intra-node and inter-container throughput
|
||||
on the same host.
|
||||
|
||||
- Language Support
|
||||
|
||||
The TIPC user API has support for C, Python, Perl, Ruby, D and Go.
