From 638d5dbd78ea81c943959e2f2c65c109e5278a78 Mon Sep 17 00:00:00 2001 From: Ake Koomsin Date: Tue, 1 Nov 2022 15:42:53 +0900 Subject: target/arm: Honor HCR_E2H and HCR_TGE in ats_write64() We need to check HCR_E2H and HCR_TGE to select the right MMU index for the correct translation regime. To check for EL2&0 translation regime: - For S1E0*, S1E1* and S12E* ops, check both HCR_E2H and HCR_TGE - For S1E2* ops, check only HCR_E2H Signed-off-by: Ake Koomsin Message-id: 20221101064250.12444-1-ake@igel.co.jp Reviewed-by: Richard Henderson Signed-off-by: Peter Maydell --- target/arm/helper.c | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) (limited to 'target') diff --git a/target/arm/helper.c b/target/arm/helper.c index 077581187e..d8c8223ec3 100644 --- a/target/arm/helper.c +++ b/target/arm/helper.c @@ -3501,19 +3501,22 @@ static void ats_write64(CPUARMState *env, const ARMCPRegInfo *ri, MMUAccessType access_type = ri->opc2 & 1 ?
