From 379245cdf1d1efc1eccc38bf0cc985dae232123d Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 2 Dec 2014 15:48:24 +0000 Subject: [PATCH] MIPS: KVM: Expose FPU registers Add KVM register numbers for the MIPS FPU registers, and implement access to them with the KVM_GET_ONE_REG / KVM_SET_ONE_REG ioctls when the FPU capability is enabled (exposed in a later patch) and present in the guest according to its Config1.FP bit. The registers are accessible in the current mode of the guest, with each sized access showing what the guest would see with an equivalent access, and like the architecture they may become UNPREDICTABLE if the FR mode is changed. When FR=0, odd doubles are inaccessible as they do not exist in that mode.
