Unable to Update the Intel® QuickAssist Technology (Intel® QAT) Driver in Linux*

• The QAT services were stopped and the previous driver was uninstalled.
• Error messages encountered during the installation of the new driver:

  modprobe: ERROR: could not insert 'qat_c62x': Exec format error
  modprobe: ERROR: could not insert 'usdm_drv': Exec format error
  modprobe: ERROR: could not insert 'qat_api': Exec format error

1. Uninstall any previous Intel® QAT driver installations, especially if multiple kernels are present.
2. Run the command to check for leftover installations: find / -name qat_c62x.ko
3. If multiple results are shown, uninstall those previous installations to avoid conflicts. An example of multiple installations look like below:

   /lib/modules/5.4.0/updates/drivers/crypto/qat/qat_c62x/qat_c62x.ko
   /lib/modules/4.15.0-72-generic/updates/drivers/crypto/qat/qat_c62x/qat_c62x.ko
   /lib/modules/4.20.1-042001-generic/kernel/drivers/crypto/qat/qat_c62x/qat_c62x.ko
   /QAT-old/quickassist/qat/drivers/crypto/qat/qat_c62x/qat_c62x.ko
   /QAT/quickassist/qat/drivers/crypto/qat/qat_c62x/qat_c62x.ko

4. Run the following commands to clean and install the new driver:

   make clean
   ./configure
   make -j install
