For instance invalidations patterns like "invalidate 32 4kB pages starting from 0xff395000 are not correctly handled" due to the fact the previous fix only made sure the number of invalidated pages were a power of 2 but did not properly handle the start address was not aligned with the range.

This isn't correct: if the CPU is not in Secure state then EOIR1 will only complete Group 1 NS IRQs, but if the CPU is in EL3 it can complete both Group 1 S and Group 1 NS IRQs. (The pseudocode ICC_EOIR1_EL1 makes this clear.) We were also missing the logic to prevent EOIR0 writes completing G0 IRQs when they should not. Rearrange the logic to first identify the group of the current highest priority interrupt and then look at whether we should complete it or ignore the access based on which register was accessed and the state of the CPU. The resulting behavioural change is: * EL3 can now complete G1NS interrupts * G0 interrupt completion is now ignored if the GIC and the CPU have the security extension enabled and the CPU is not secure Reported-by: Chan Kim <ckim@etri.re.kr> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20210510150016.24910-1-peter.maydell@linaro.org --- hw/intc/arm_gicv3_cpuif.c | 48 ++++++++++++++++++++++++++------------- 1 file changed, 32 insertions(+), 16 deletions(-) diff --git a/hw/intc/arm_gicv3_cpuif.c b/hw/intc/arm_gicv3_cpuif.c index XXXXXXX..XXXXXXX 100644 --- a/hw/intc/arm_gicv3_cpuif.c +++ b/hw/intc/arm_gicv3_cpuif.c @@ -XXX,XX +XXX,XX @@ static void icc_eoir_write(CPUARMState *env, const ARMCPRegInfo *ri, GICv3CPUState *cs = icc_cs_from_env(env); int irq = value & 0xffffff; int grp; + bool is_eoir0 = ri->crm == 8; - if (icv_access(env, ri->crm == 8 ?

We were not getting this logic entirely correct. Whether we use one of the Secure stack pointers or one of the Non-Secure stack pointers depends on the EXCRET.S bit. However, whether we use the MSP or the PSP then depends on the SPSEL bit in either the CONTROL_S or CONTROL_NS register. We were incorrectly selecting MSP vs PSP based on the EXCRET.SPSEL bit. (In the pseudocode this is in the PopStack() function, which calls LookUpSp_with_security_mode() which in turn looks at the relevant CONTROL.SPSEL bit.) The buggy behaviour wasn't noticeable in most cases, because we write EXCRET.SPSEL to the CONTROL.SPSEL bit for the S/NS register selected by EXCRET.ES, so we only do the wrong thing when EXCRET.S and EXCRET.ES are different. This will happen when secure code takes a secure exception, which then tail-chains to a non-secure exception which finally returns to the original secure code.

The "sat" pointer acts both as a boolean for control of saturating behavior and controls the difference in behavior between neon and sve -- QC bit or no QC bit. Widen the shift operand in the new helpers, as the SVE2 insns treat the whole input element as significant. For the neon uses, truncate the shift to int8_t while passing the parameter. Implement right-shift rounding as tmp = src >> (shift - 1); dst = (tmp >> 1) + (tmp & 1); This is the same number of instructions as the current tmp = 1 << (shift - 1); dst = (src + tmp) >> shift; without any possibility of intermediate overflow.

They take up the space which was previously UNPREDICTABLE MOVS and ORRS encodings with Rm == 13 or 15. Implement the long shifts by immediate, which perform shifts on a pair of general-purpose registers treated as a 64-bit quantity, with an immediate shift count between 1 and 32. Awkwardly, because the MOVS and ORRS trans functions do not UNDEF for the Rm==13,15 case, we need to explicitly emit code to UNDEF for the cases where v8.1M now requires that. (Trying to change MOVS and ORRS is too difficult, because the functions that generate the code are shared between a dozen different kinds of arithmetic or logical instruction for all A32, T16 and T32 encodings, and for some insns and some encodings Rm==13,15 are valid.) We make the helper functions we need for UQSHLL and SQSHLL take a 32-bit value which the helper casts to int8_t because we'll need these helpers also for the shift-by-register insns, where the shift count might be < 0 or > 32.

Like the long-shifts-by-immediate, these encodings sit in the space that was previously the UNPREDICTABLE MOVS/ORRS with Rm==13,15. Because LSLL_rr and ASRL_rr overlap with both MOV_rxri/ORR_rrri and also with CSEL (as one of the previously-UNPREDICTABLE Rm==13 cases), we have to move the CSEL pattern into the same decodetree group.
