Replace the current delay timeout mechanism with a spinlock.
Both mechanisms try to eliminate the possibility of an in-flight
async op accessing state that has been destroyed by stop().
But the spinlock is less arbitrary.
This now ensures that finalizeReq is indeed called from mrntt,
since exception-experiencing threads will post an exceptionInd
to mrntt, which will then call finalizeReq.
We added a new centralized OpenCL Compute manager. This can later
be extended to support CUDA, SyCL, etc. SMO can be configured at
build time to choose which API it will use for compute.
Moreover, the ComputeMgr allows us to register buffers which are
available to all cl_contexts.
This symbol is defined as a static member object inside of a
boost detail header. When boost headers are used in a project
that uses Boost in both the main binary as well as dlopen()'d
shlibs, the top_ symbol gets duplicated and the metadata gets
partitioned.
We use the Boost shlib to unify both the main binary and the
shlibs to use the same memory address for top_.
This involves marking the templated object call_stack::top_ as
"extern" and then declaring to Boost that we intend to use the
shlibs.
All Cologexes (both Cologexes and CologexSets) are now categorized
as Concepts.
Goals are now also Concepts -- they inherit from Concept as a base
class.
Using Concept as the base class for both Cologex and CologexSet
allows us to treat both cologexes and cologexsets the same way
when comparing in the abstract.
Since we have no choice but to access the sh_ptr<SenseApiLib> for
a lib before we can get its Qutex, we use this flag to ensure that
we can know whether the SenseApiLib data structure and its Qutex
are still valid when we enter -- i.e, we ensure that the SenseApiLib
object wasn't destroyed under our feet.
This function is the backbone for the DeviceReattacher daemon. It
assembles a list of all DA specs which are known to Mrntt, but which
haven't been successfully attached as yet, and attempts to attach
them.
This method wraps around attachAllUnattachedDevicesFromReq and supplies
it with a sh_ptr<> collection of all DASpecs parsed by the DAP parser
from the cmdline.
The initialization sequence now correctly initializes all DAP specs
given on the cmdline again.
This method now accepts a sh_ptr<vector<DeviceAttachmentSpec>> to
tell it specifically which specs to attempt to attach.
This enables us to implement different frontends that supply it
with collections of devices from different sources (GUI, cmdline,
previously failed-to-attach/hot-removed devices, etc).
SMO temporarily initializes none of the devices from the cmdline
during this commit as we transition to implementing the cmdline
collection frontend.
We've renamed these now to better reflect what they do.
* attachAllSenseDevicesFromSpecsReq=>attachAllUnattachedDevicesFromReq
* detachAllSenseDevicesReq=>detachAllAttachedDeviceRoles
This is also the first step in changing
attachAllUnattachedDevicesFrom to accept a sh_ptr<> to a collection
of DeviceAttachmentSpecs. This will enable us to unify the underlying
spec attachment logic and just create several front-ends for attaching
specs from multiple sources.
This performs a more complete device initialization and attachment
sequence. We'll do the corresponding teardown in the shutdown
sequence later.
We might probably do it as deviceRoleGoneAwayInd()
We've decided to add a separate notion of a DeviceRole to track attached
device roles now. We no longer use the collection of deviceSpecs to
track which roles have been attached. Rather, this list will simply
collate all known deviceAttachment specs which are expected to be
maintained in an attached state.
SMO can periodically scan through these and cross-reference this
collection with the collection of attachedDeviceRoles. Then it can
re-try to attach those which aren't currently attached at any given
moment. This will give resilience against device attachment failures
or device resets/malfunctions, at runtime.
