Merge branch 'sg_nents' into rdma.git for-next
From Maor Gottlieb ==================== Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges. Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases. ==================== Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * 'sg_nents': RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append

* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "smsc,lan<model>", "smsc,lan9115"
|
||||
- reg : Address and length of the io space for SMSC LAN
|
||||
- interrupts : one or two interrupt specifiers
|
||||
- The first interrupt is the SMSC LAN interrupt line
|
||||
- The second interrupt (if present) is the PME (power
|
||||
management event) interrupt that is able to wake up the host
|
||||
system with a 50ms pulse on network activity
|
||||
- phy-mode : See ethernet.txt file in the same directory
|
||||
|
||||
Optional properties:
|
||||
- reg-shift : Specify the quantity to shift the register offsets by
|
||||
- reg-io-width : Specify the size (in bytes) of the IO accesses that
|
||||
should be performed on the device. Valid value for SMSC LAN is
|
||||
2 or 4. If it's omitted or invalid, the size would be 2.
|
||||
- smsc,irq-active-high : Indicates the IRQ polarity is active-high
|
||||
- smsc,irq-push-pull : Indicates the IRQ type is push-pull
|
||||
- smsc,force-internal-phy : Forces SMSC LAN controller to use
|
||||
internal PHY
|
||||
- smsc,force-external-phy : Forces SMSC LAN controller to use
|
||||
external PHY
|
||||
- smsc,save-mac-address : Indicates that mac address needs to be saved
|
||||
before resetting the controller
|
||||
- reset-gpios : a GPIO line connected to the RESET (active low) signal
|
||||
of the device. On many systems this is wired high so the device goes
|
||||
out of reset at power-on, but if it is under program control, this

New object placement and region query uAPI
|
||||
==========================================
|
||||
Starting from DG1 we need to give userspace the ability to allocate buffers from
|
||||
device local-memory. Currently the driver supports gem_create, which can place
|
||||
buffers in system memory via shmem, and the usual assortment of other
|
||||
interfaces, like dumb buffers and userptr.
|
||||
|
||||
To support this new capability, while also providing a uAPI which will work
|
||||
beyond just DG1, we propose to offer three new bits of uAPI:
|
||||
|
||||
DRM_I915_QUERY_MEMORY_REGIONS
|
||||
-----------------------------
|
||||
New query ID which allows userspace to discover the list of supported memory
|
||||
regions(like system-memory and local-memory) for a given device. We identify
|
||||
each region with a class and instance pair, which should be unique. The class
|
||||
here would be DEVICE or SYSTEM, and the instance would be zero, on platforms
|
||||
like DG1.
|
||||
|
||||
Side note: The class/instance design is borrowed from our existing engine uAPI,
|
||||
where we describe every physical engine in terms of its class, and the
|
||||
particular instance, since we can have more than one per class.
|
||||
|
||||
In the future we also want to expose more information which can further
|
||||
describe the capabilities of a region.

||||

||||

||||
:functions: drm_i915_gem_memory_class drm_i915_gem_memory_class_instance drm_i915_memory_region_info drm_i915_query_memory_regions
|
||||
|
||||
GEM_CREATE_EXT
|
||||
--------------
|
||||
New ioctl which is basically just gem_create but now allows userspace to provide
|
||||
a chain of possible extensions. Note that if we don't provide any extensions and
|
||||
set flags=0 then we get the exact same behaviour as gem_create.
|
||||
|
||||
Side note: We also need to support PXP[1] in the near future, which is also
|
||||
applicable to integrated platforms, and adds its own gem_create_ext extension,
|
||||
which basically lets userspace mark a buffer as "protected".
|
||||
|
||||
.. kernel-doc:: include/uapi/drm/i915_drm.h
|
||||
:functions: drm_i915_gem_create_ext
|
||||
|
||||
I915_GEM_CREATE_EXT_MEMORY_REGIONS
|
||||
----------------------------------
|
||||
Implemented as an extension for gem_create_ext, we would now allow userspace to
|
||||
optionally provide an immutable list of preferred placements at creation time,
|
||||
in priority order, for a given buffer object. For the placements we expect
|
||||
them each to use the class/instance encoding, as per the output of the regions
|
||||
query. Having the list in priority order will be useful in the future when
|
||||
placing an object, say during eviction.
|
||||
|
||||
.. kernel-doc:: include/uapi/drm/i915_drm.h
|
||||
:functions: drm_i915_gem_create_ext_memory_regions
|
||||
|
||||
One fair criticism here is that this seems a little over-engineered[2]. If we
|
||||
just consider DG1 then yes, a simple gem_create.flags or something is totally
|
||||
all that's needed to tell the kernel to allocate the buffer in local-memory or
|
||||
whatever. However looking to the future we need uAPI which can also support
|
||||
upcoming Xe HP multi-tile architecture in a sane way, where there can be
|
||||
multiple local-memory instances for a given device, and so using both class and
|
||||
instance in our uAPI to describe regions is desirable, although specifically
|
||||
for DG1 it's uninteresting, since we only have a single local-memory instance.
|
||||
|
||||
Existing uAPI issues
|
||||
====================
|
||||
Some potential issues we still need to resolve.
|
||||
|
||||
I915 MMAP
|
||||
---------
|
||||
In i915 there are multiple ways to MMAP GEM object, including mapping the same
|
||||
object using different mapping types(WC vs WB), i.e multiple active mmaps per
|
||||
object. TTM expects one MMAP at most for the lifetime of the object. If it
|
||||
turns out that we have to backpedal here, there might be some potential
|
||||
userspace fallout.
|
||||
|
||||
I915 SET/GET CACHING
|
||||
--------------------
|
||||
In i915 we have set/get_caching ioctl. TTM doesn't let us to change this, but
|
||||
DG1 doesn't support non-snooped pcie transactions, so we can just always
|
||||
allocate as WB for smem-only buffers. If/when our hw gains support for
|
||||
non-snooped pcie transactions then we must fix this mode at allocation time as
|
||||
a new GEM extension.
|
||||
|
||||
This is related to the mmap problem, because in general (meaning, when we're
|
||||
not running on intel cpus) the cpu mmap must not, ever, be inconsistent with
|
||||
allocation mode.
|
||||
|
||||
Possible idea is to let the kernel picks the mmap mode for userspace from the
|
||||
following table:
|
||||
|
||||
smem-only: WB. Userspace does not need to call clflush.
|
||||
|
||||
smem+lmem: We only ever allow a single mode, so simply allocate this as uncached
|
||||
memory, and always give userspace a WC mapping. GPU still does snooped access
|
||||
here(assuming we can't turn it off like on DG1), which is a bit inefficient.
|
||||
|
||||
lmem only: always WC
|
||||
|
||||
This means on discrete you only get a single mmap mode, all others must be
|
||||
rejected. That's probably going to be a new default mode or something like
|
||||
that.

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.
