Jon Hunter 5a54d4161a drivers: Fix build for Linux v6.12
In Linux v6.12 the definition 'no_llseek' was finally removed. Since
Linux v6.0 it had been redefined as NULL. Add a test to conftest to
determine if 'no_llseek' is present and if not then it is no longer
necessary to populate this and we can leave as NULL.

Build NvSciIpc KMD for DRIVE x86
================================

1) install kernel header package
sudo apt-get install linux-headers-`uname -r`

check version of desktop using "uname -r" command.
kernel version must be 5.4.0+.

2) link common header files (NVIDIA internal dev only)
export NVSCIIPC_INCLUDE=${PWD}/../../../include
ln -s ${NVSCIIPC_INCLUDE}/linux ./
ln -s ${NVSCIIPC_INCLUDE}/uapi ./

3) build
make -C /lib/modules/`uname -r`/build M=${PWD} modules

4) install NvSciIpc KMD
sudo make -C /lib/modules/`uname -r`/build M=${PWD} modules_install
sudo depmod -a

nvsciipc.ko will be installed in /lib/modules/`uname -r`/updates/nvsciipc.ko

[NOTE] If kernel module installation is failed by missing signing key, follow steps below

** create x509.genkey
echo -e "[ req ] \n\
default_bits = 4096 \n\
distinguished_name = req_distinguished_name \n\
prompt = no \n\
x509_extensions = myexts \n\
\n\
[ req_distinguished_name ] \n\
CN = Modules \n\
\n\
[ myexts ] \n\
basicConstraints=critical,CA:FALSE \n\
keyUsage=digitalSignature \n\
subjectKeyIdentifier=hash \n\
authorityKeyIdentifier=keyid" > x509.genkey

** generate signing key
openssl req -new -nodes -utf8 -sha512 -days 36500 -batch -x509 -config x509.genkey -outform DER -out signing_key.x509 -keyout signing_key.pem

** move signing key to kernel module folder of desktop
sudo mv signing_key.* /lib/modules/`uname -r`/build/certs/

5) clean
make -C /lib/modules/`uname -r`/build M=${PWD} clean

6) load NvSciIpc KMD
You can load NvSciIpc KMD during desktop boot.
sudo vi /etc/modules-load.d/modules.conf
add "nvsciipc" to this file

For manual loading KMD, do "sudo insmod nvsciipc.ko"
