When UMD requests to flush specific request that was submitted
to HW/FW, return error code back to userspace and log the particular
active request id if the device does not flush active request.
Currently devices that do not support flushing a specific active
request are ICP, OPE, and CRE.
Return error if there is no request to flush upon UMD call to
flush specific request.
Print all ICP requests' id from all active streams when encountering
WD or ICP fatal errors.

Add infrastructure to allow multiple ICP subdevices to co-exist
with each subdevice exposed to UMD individually. All operations
including ioctl on each subdevice are discrete from another's. Add
a new private field in node structure to point to which subdev
the node belongs to. Add a new ICP1 device type and expose the type
associated with ICP1 to userspace for identifying the second ICP.
Each subdevice's unique name is derived from "cam-icp". The name is
then appended with a cell-index if it exists. If there are multiple
nodes in DTSI to be probed, each node must contain cell-index to
differentiate them.
For each subdevice, it is expected to have a unique node in DTSI
with unique compatible string to probe the sd during boottime.

Update from error injection framework to event injection framework to
support PF event inducement and node event. Different set of user
input parameters are required dependent on which event to injection.
ICP and ISP support error event and page fault event injection. JPEG
supports node event and page fault event injection. However, buf done
error injection is only supported for JPEG and ICP.
Create a query API to check whether PF is fatal for a context bank.
Using the API, if PF is fatal, page fault event injection is not
supported for the device that owns the context bank.
Make change to JPEG context event callback handling to account for
various events including Event Injection event.

Upon Page Fault, smmu driver invokes faulted client's callback
which looks for faulted buffer and context. The client driver
can be ISP, ICP, JPEG, IFE CDM and CPAS CDM. The driver then
fills PF msg struct, logs related info, and notify PF msg to
userspace. Userspace is expected to abort and calls to shut
down kernel drivers. When Titan powers on next session, CAMSS
undergoes async reset.
This change also ensures the page fault related changes added
to TFE, OPE, CRE do not break the drivers compilation.

In subdev close call if CRM is still active wait for shutdown
from CRM [media device]. Remove subdevice check for active
handles, shutdown to happen irrespective of any active context.
If CRM is not active, subdevice shutdown should ensure there is
no access to kernel allocated buffers since at this point
memmgr is de-initialized.
As part of ICP close, remove usage of HFI queues, trigger PIL
to transfer FW memory ownership back to HLOS and power off ICP.

In current implementation, cam_ctx_req has a array of
hw_update_entries, in_map_entries and out_map_entries. Each
context has array of N requests. Memory for all contexts is
allocated during probe. This causes a huge memory remaining
unutilized.
This commit moves the memory allocation to context acquire time
and freeing this memory during context release. In place
of using array, now dynamic allocation is used.
A top level calculation shows a memory reduction of around 2M-
2.5M with this change including all the camera drivers.

Currently when page fault happen, iommu driver callers camera
handler with CB details and iova address which caused the page
fault. With iommu iova address cam smmu driver finds the
closest mapping address for that cb and call the
corresponding driver to find the which port caused page fault.
This has limitation has page fault address always not mapped.
New approach is get the page fault ids from iommu driver.
Based on the Pid and Mid values, get the HW id and port ids,
go through all context which has this hw id and port id and log
the data. Once context id is identified, log the acquire data and
last consumed client address details. Dump the hw register data
in the given buffer. Send the smmu page fault event through
v4l2 queue to user.

When user space detects an error or does not receive
response for a request, Lets do a reset(LDAR) is triggered.
Before LDAR, user space sends flush command to the
kernel space.
In order to debug the cause for this situation and to dump
the information, user space sends a dump command to the
kernel space before sending flush.
As a part of this command, it passes the culprit request id
and the buffer into which the information can be dumped.
Kernel space traverses across the drivers and find the culprit hw
and dumps the relevant information in the buffer.
This data is written to a file for offline processing.
This commit dumps the information for NRT devices; JPEG,
LRME, FD and ICP.
For LRME, FD, JPEG context information is dumped.
FOR ICP, fw image is dumped.

When the userspace issues flush, ISP driver needs to ensure that
wait and active list requests are flushed and corresponding
buffer fences are signaled with error. For active and wait lists
IFE hardware is stopped immediately. Therefore IFE must also be

after receiving init packet again.
