- The VI is allowed to access the whole of the Guest VM currently as it
is a stage-2 SMMU device. Hence it can read and write to any memory.
This may lead to breach of confidentiality and integrity. In order to
restrict the VI from accessing the whole VM, a mempool is being created
by HV that would restrict access to VI to just the mempool memory.
- In nvmap, we have some special rules for IVM carveout like if user
specify IVM carveout to allocate from, then if first IVM carveout does
not have sufficient memory then nvmap tries to allocate from next IVM
carveout. We don't want these rules applicable for VI mempool heap,
hence only carveout initialization part would remain similar to IVM
carveouts but rest of the operations would be performed normally like
any other carveout.
- Add DT binding doc for VI-carveout.

Add a new sysfs interface that allows toggling camera diagnostics on and
off at runtime without deallocating memory resources. This enhances the
camera-diagnostics driver functionality by:
- Adding a new 'control' sysfs attribute for starting/stopping diagnostics
- Implementing intelligent state checking to avoid unnecessary operations
- Providing better user feedback about the current diagnostic state
- Preserving allocated memory between stop/start cycles
The implementation checks if diagnostics are already running or already
stopped before attempting state changes, preventing redundant operations
and providing informative messages to users.
This allows us to run isp-falcon-memtest, which conflicts with
camera-diagnostics driver.

This commit expands the camera-diagnostics driver to add
support for ISP PFSD tests. The implementation:
- Adds diagnostics IVC communication between kernel and RCE firmware
- Implements ISP SDL test vector loading, verification, and execution
- Provides proper memory allocation and IOMMU mapping across devices
- Supports multiple ISP instances with chip-specific configurations
(T234/ISP6 and T264/ISP7)
- Creates sysfs interface for diagnostic status reporting
- Adds proper error handling and resources cleanup
- Implements CRC validation for test vectors
The driver enables hardware safety diagnostics for camera subsystems
to ensure reliability and functional safety of the camera pipeline.
New header files:
- camrtc-diag-messages.h: Defines messages for IVC communication
- camrtc-diag.h: Contains common diagnostic data structures

After a deeper analysis, it was found that multithreaded cache flush is
not required. Only gathering the pages and then doing cache flush is
enough to get the perf improvement, the cache flush time of each page is
almost half in this case as compared with not gathering the pages. So it
means there is continuous cache eviction is happening. So, while
allocating big pages from allocator, instead of allocating one big page
and flushing it, allocate all required big pages and then flush pages
at last.
