I just tried to build for arm64 but PREEMPT_RT is not available anymore. Looks like ARCH_SUPPORTS_RT is only available for !KVM. Thanks, Daniel

Thanks, Daniel

Dear RT folks! I'm pleased to announce the v5.9-rc8-rt12 patch set. Changes since v5.9-rc8-rt11: - The kernel test robot reported a few warnings due to the printk code and a compile error in the powerpc architecture. Known issues - It has been pointed out that due to changes to the printk code the internal buffer representation changed. This is only an issue if tools like `crash' are used to extract the printk buffer from a kernel memory image. The delta patch against v5.9-rc8-rt11 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/incr/patch-5.9-rc8-rt11-rt12.patch.xz You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.9-rc8-rt12 The RT patch against v5.9-rc8 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/older/patch-5.9-rc8-rt12.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/older/patches-5.9-rc8-rt12.tar.xz Sebastian
