When building the DLA KMD driver with GCC 13 the following error is

The 'clk_cap_kobj' member of 'nvhost_device_data' structure is not a
pointer to a structure but a structure and so the address of the

'clk_cap_attrs' member which is a pointer to memory that is allocated.

Once we complete EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED event handling, it
doesn't reset the complition variable. Which causes
dce_wait_interruptible to exit early without waiting in next cycle.
This patch fixes the same by resetting complition variable after use for
EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED.

When the device is in suspend mode, There is no point to update
actmon count weight and send ICC request for the device.
If ICC request is sent for the device in suspend mode, in osidle state,
the default EMC frequency will be affected due to the accumulated ICC
bandwidth QoS constraint, and affect the overall osidle power.

Update the hv-ivc.h header to ensure that these function stubs are

Finally, move populating the ccflags to the top-level Makefile and use
the subdir-ccflags directive to ensure the ccflags are passed to all

Deferred dmabuf unmapping is being removed from kernel.
So, add similar support to cache sgt in NvMap.
During map_dma_buf() call, NvMap will create a mapping and an sgt
corresponding to it. It will also cache this sgt.
When unmap_dma_buf() is called for same sgt, NvMap will not unmap
the mappings. It will simply return from there.
Next time when the mapping request comes for same dmabuf, it will
look for existing sgt in cache and return it. This significantly
reduces mapping overhead for same buffer when it's mapped and unmapped
multiple times.
Free the sgt and unmap only when corresponding buffer is freed. When
all references from a buffer are removed, dmabuf_release() will be
called where sgt will be freed.

The function tegra_fuse_control_read() is not used anywhere and so we

When CONFIG_DEBUG_FS is disabled, build errors are seen in the
following 2 drivers:
1. bpmpfw - The build error was seen because bpmp-debugfs.c was
getting compiled even when CONFIG_DEBUG_FS was disabled.
2. ufs - The build error was seen due to a couple of reasons:
- Function debugfs_provision_init is defined in a file that is
protected with CONFIG_DEBUG_FS, but is called from another file
unconditionally.
- In ufs-tegra-common.c, there are calls to debugfs_* functions, but
inclusion of the standard header debugfs.h is protected under
CONFIG_DEBUG_FS.
Fix these issues with this change.

Issue:
MGBE0 ASID is getting programmed for all the MAC instances
which inturn causing the data transfer failures.Macsec is not enable
and hence instance_id is not getting updated to the corresponding mac
instance number and hence all mac instance_id's are initialized with 0.
Since ASID programming is based on mac instance_id, all MACs are
programmed with MGBE0 MAC instance id.
Fix:
Moved reading of instance_id from DT out of macsec_probe and hence the
instance_id gets updated irrespective of MAC sec enable/disable.

nvethernet support for Linux v6.3 and the following errors are observed.
failed to register MDIO bus (nvethernet_mdio_bus)
net eth0: failed to register MDIO bus
Fix this by adding the necessary read/write_c45 callbacks in the

- is set into DAR (Disable Automatic Retransmission) mode
- and Protocol Exception Handling is enabled
- and PXE (Protocol Exeception Event) is generated
then no TCF (Transmission cancellation Finished) event is generated.
This leads to mismatch between internal driver state and mttcan HW
state. This results in "no buffer space available" error.
This patch clears the driver internal state in close callback to
handle this situation.
