Long time no RFC! I finally had time to get the next version of the Linux driver side of virtio-mem into shape, incorporating ideas and feedback from previous discussions. This RFC is based on the series currently on the mm list: - [PATCH 0/3] Remove __online_page_set_limits() - [PATCH v1 0/3] mm/memory_hotplug: Export generic_online_page() - [PATCH v4 0/8] mm/memory_hotplug: Shrink zones before

This patch series aims to move the logical block size checking to the block code. This was inspired by missing check for valid logical block size in virtio-blk which causes the kernel to crash in a weird way later on when it is invalid. I added blk_is_valid_logical_block_size which returns true iff the block size is one of supported sizes. I added this check to virtio-blk, and also converted

Hi, here is the next version of changes to enable Linux to run as an SEV-ES guest. The code was rebased to v5.7-rc3 and got a fair number of changes since the last version. What is SEV-ES ============== SEV-ES is an acronym for 'Secure Encrypted Virtualization - Encrypted State' and means a hardware feature of AMD processors which hides the register state of VCPUs to the hypervisor by
