[PULL v9 02/13] confidential guest support: Introduce new confidential guest support class

When AMD's SEV memory encryption is in use, flash memory banks (which are initialed by pc_system_flash_map()) need to be encrypted with the guest's key, so that the guest can read them. That's abstracted via the kvm_memcrypt_encrypt_data() callback in the KVM state.. except, that it doesn't really

[PATCH v2 13/16] tcg: Expand usadd/ussub with umin/umax

For usadd, we only have to consider overflow. Since ~B + B == -1, the maximum value for A that saturates is ~B. For ussub, we only have to consider underflow. The minimum value that saturates to 0 from A - B is B. Signed-off-by: Richard Henderson --- tcg/tcg-op-vec.c | 37

[PATCH v2 02/15] tcg/arm: Add host vector framework

This operation is critical to staying within the interpretation loop longer, which avoids the overhead of setup and teardown for many TBs. The check in tcg_prologue_init is disabled because TCI does want to use NULL to indicate exit, as opposed to branching to a real epilogue. Signed-off-by: Rich
