In certain circumstances, you may need to update the kernel and kernel-devel packages to enable NAM Probe software operation (installation of hardware drivers). On arm64, mainline already does the right thing. Otherwise Remus can run most any PV domU in a degraded performance mode. 3 and older will end after release 396. For 32 bit programs running on a 32 bit kernel, the same mechanism is used as for 64 bit programs running on a 64 bit kernel. The "nvmem" attribute does respect the setting of the root_only configuration bit, so do the same for "eeprom". The differences in this approach versus other is largely due to the architecture support and the split build/source directory of the kernel. Replace "kernel-devel" with "kernel-PAE-devel" if using a PAE kernel. This is my first post to this forum. 1 version of the Saffire 6 USB is not officially supported with Windows 10 1903, though it may work. │ │ (0x1000000) Alignment value to which kernel should be aligned │ │ │ │ -*- Support for hot-pluggable CPUs │ │ │ │ [ ] Compat VDSO support │ │. 3 or later), to remove the high-mapped VDSO mapping and to exclusively use the randomized VDSO.
