Use git to get recent kernels from github. Adjust NOVA patch to compile with recent github version. Patch and use makefile of NOVA microkernel to avoid duplicated (and outdated) makefile in Genode Furthermore, this patch adds support for using NOVA on x86_64. The generic part of the syscall bindings has been moved to 'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific parts are located at 'base-nova/include/32bit/nova/syscalls.h' and 'base-nova/include/64bit/nova/syscalls.h' respectively. On x86_64, the run environment boots qemu using the Pulsar boot loader because GRUB legacy does not support booting 64bit ELF executables. In addition to the NOVA-specific changes in base-nova, this patch rectifies compile-time warnings or build errors in the 'ports' and 'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver builds for 32bit only and needed an adaptation to NOVAs changed bindings) Fixes #233, fixes #234 |

This directory contains patches for the Nova Hypervisor prerelease 0.3 :'utcb.patch': It is not possible to destroy UTCBs in NOVA 0.3. Therefore UTCBs cannot be re-used which may lead to the exhaustion of contexts within Genode. This patch simply causes NOVA to ignore this issue. Applying the patches -------------------- To apply a patch to the NOVA hypervisor, use the 'patch' command. First check the directory given at the header of the patch. It may contain a directory prefix (such as 'a/'), which does not actually exist. This prefix is usually generated by the tool used to create the patch. In this case, use the '-p' option of the patch command. To apply the patch with the first part of the path stripped, issue the following command (make sure that you changed to the base directory of the NOVA hypervisor): ! patch -p1 < /path/to/utcb.patch
