KVM: arm64: Fix debug register indexing
Commit 03fdfb2690099 ("KVM: arm64: Don't write junk to sysregs on reset") flipped the register number to 0 for all the debug registers in the sysreg table, hereby indicating that these registers live in a separate shadow structure. However, the author of this patch failed to realise that all the accessors are using that particular index instead of the register encoding, resulting in all the registers hitting index 0. Not quite a valid implementation of the architecture... Address the issue by fixing all the accessors to use the CRm field of the encoding, which contains the debug register index. Fixes: 03fdfb2690099 ("KVM: arm64: Don't write junk to sysregs on reset") Reported-by: Ricardo Koller <> Signed-off-by: Marc Zyngier <> Cc:
