mainline inclusion from mainline-6.10-rc1 commit 9752fed8f67c258213535d72f7669279921a6491 category: feature bugzilla: RVCK-Project#262 -------------------------------- Originally, the use of kvm->lock in SBI_EXT_HSM_HART_START also avoids the simultaneous updates to the reset context of target VCPU. Since this lock has been replace with vcpu->mp_state_lock, and this new lock also protects the vcpu->mp_state. We have to add a separate lock for vcpu->reset_cntx.

mainline inclusion from mainline-6.14-rc1 commit 023c15151fbb65f8dde23e28af1d6d4382404d58 category: feature bugzilla: RVCK-Project#262 -------------------------------- Implement a KVM SBI SUSP extension handler. The handler only validates the system suspend entry criteria and prepares for resuming in the appropriate state at the resume_addr (as specified by the SBI spec), but then it forwards the call to the VMM where any system suspend behavior may be implemented. Since VMM support is needed, KVM disables the extension by default.

category: feature
bugzilla: RVCK-Project#262
--------------------------------
The spec says sleep_type is 32 bits wide and "In case the data is
defined as 32bit wide, higher privilege software must ensure that it
only uses 32 bit data." Mask off upper bits of sleep_type before
using it.
