2018-10-31kvm: simplify floating point logic.Adin Scannell
This reduces the number of floating point save/restore cycles required (since we don't need to restore immediately following the switch, this always happens in a known context) and allows the kernel hooks to capture state. This lets us remove calls like "Current()". PiperOrigin-RevId: 219552844 Change-Id: I7676fa2f6c18b9919718458aa888b832a7db8cab

2018-06-06Split PCID implementation from page tables.Adin Scannell
Instead of associating a single PCID with each set of page tables (which will reach the maximum quickly), allow a dynamic pool for each vCPU. This is the same way that Linux operates. We also split management of PCIDs out of the page tables themselves for simplicity. PiperOrigin-RevId: 199585631 Change-Id: I42f3486ada3cb2a26f623c65ac279b473ae63201
2018-05-30Change ring0 & page tables arguments to structs.Adin Scannell
This is a refactor of ring0 and ring0/pagetables that changes from individual arguments to opts structures. This should involve no functional changes, but sets the stage for subsequent changes. PiperOrigin-RevId: 198627556 Change-Id: Id4460340f6a73f0c793cd879324398139cd58ae9
