c87d8891b9 msm: camera: common: Enhance error injection framework
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.

c52c83e7ce msm: camera: common: Page Fault notification to userspace
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.

d785949196 msm: camera: common: Change shutdown sequence for subdevices
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.

2ebae4fabe msm: camera: req_mgr: Enhance camera v4l2 subdev shutdown sequence
when provider crash occurred, there was a CSID lane overflow
observed due to shutdown sequence from CRM(sensor, csid, csiphy).
To fix the issue need to change the shutdown sequence
(csid, sensor, csiphy).

This change will update the devices sequence in order while registering
and close the sequence accordingly.

1a5797c6a8 msm: camera: common: Optimize cam context memory
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.

b746c4f527 msm: camera: core: Send event on smmu page fault
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.

dbc2111c4f msm: camera: common: LDAR dump NRT devices information
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.

aaab1ef87e msm: camera: isp: Stop HW immediately in flush
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
reset to ensure that VFE BUS FIFOs are cleared. Start IFE HW
after receiving init packet again.
