2024-04-16Change remoteproc to map ROM as device memoryMikael Olsson
The ROM is memory attached to the remote processor and should be mapped as device memory rather than normal memory to ensure memory transactions are handled correctly. To ensure this, the remoteproc driver will now map the ROM as device memory. Change-Id: I1b5f1dcd7af06bb9e1656f653d65813f7af424c3 Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-11-14Make all kernel module Sparse warnings into errors23.11-rc2Mikael Olsson
The CMake files for the kernel modules have been updated to treat all Sparse warnings as errors so that warnings cause the build to fail. Change-Id: I3682afc3beea7244bb6e0831b2baf48b95611dbc Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-11-14Fix device id data ptr using 0 instead of NULLMikael Olsson
In some of the kernel modules, 0 is used instead of NULL to indicate that there is no data in the of_device_id struct. These instances have now been replaced with NULL instead. Change-Id: I14f4aabf266bb5144107e101006e257bb7876782 Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-11-14Make internal functions static in kernel modulesMikael Olsson
Internal functions in some of the kernel modules were not marked as static and have now been fixed. Change-Id: Ibec000e4370f2438e7190a9178e05513fcccda26 Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-11-14Fix iomem pointer usage with rproc_mem_entry_initMikael Olsson
The carveout memory is being mapped with one of the ioremap functions that returns a iomem pointer and should normally only be passed to functions that request iomem pointers because they shouldn't be dereferenced. Currently, the iomem pointer is passed to rproc_mem_entry_init that is expecting a normal pointer and Sparse is generating a warnings about this. However, rproc_mem_entry_init won't dereference the pointer and can handle any pointer type so the iomem attribute is cast away when setting up the mem entry and the io_mem flag is set to indicate a iomem pointer. To ensure that the mapping is correctly managed, the mapping and unmapping is now handled with the callback functions for rproc_mem_entry_init instead of holding onto the mapping forever.

2023-11-01Add Sparse checking to kernel module buildsMikael Olsson
Sparse is a semantic checker for C that can help find potential issues in the kernel module code. To make use of the tool, the CMake files for the kernel modules have been updated to enable the tool to run on all the kernel module source files before they are built.

Changed several logs level from info to dbg and removed redundant or uninformative logging in order to reduce verbosity of the kernel modules. Change-Id: Ie9ff7f3ae6478007ea58547380b3ddfef5d280b4 Signed-off-by: Ledion Daja <ledion.daja@arm.com>
2023-10-06Add -Werror to kernel module buildsMikael Olsson
To ensure that no compilation warnings goes unnoticed, the kernel modules are now built with the -Werror flag so all warnings are treated as errors. Change-Id: Id688052bd297e366ab7ca07c508ca697ca03431e Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-10-06Fix C90 declaration order warning in remoteprocMikael Olsson
A "declaration-after-statement" warning is generated when building the remoteproc driver because C90 doesn't allow variables to be declared after a statement in a scope. To resolve this, the order of the variables at the start of the problematic scope have been reordered to comply with C90.

2023-09-25Add resource table entry for address translationMikael Olsson
To avoid having to use a hardcoded memory map to translate between the Linux physical addresses to device addresses in the firmware, a new entry type has been added to the resource table that allows the NPU remoteproc driver to provide the memory map to the firmware. With this change, the device tree layout has been changed to wrap the ethosu-rproc node with an ethosu parent node that represents the NPU subsystem. This makes it possible to use the APIs provided by the Linux kernel to perform address translation etc. The "ethosu,dma-ranges" property has been removed from ethosu-proc because the ethosu parent node provides information for how to translate between the Linux Kernel physical addresses and device addresses with a "dma-ranges" property.
