* target/arm: Fold secure and non-secure a-profile mmu indexesRichard Henderson2022-10-101-5/+1Star
| | | | | | | | | | | | | | | | | | For a-profile aarch64, which does not bank system registers, it takes quite a lot of code to switch between security states. In the process, registers such as TCR_EL{1,2} must be swapped, which in itself requires the flushing of softmmu tlbs. Therefore it doesn't buy us anything to separate tlbs by security state. Retain the distinction between Stage2 and Stage2_S. This will be important as we implement FEAT_RME, and do not wish to add a third set of mmu indexes for Realm state.

* semihosting: Allow optional use of semihosting from userspacePeter Maydell2022-09-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.

* target/arm: Trap non-streaming usage when Streaming SVE is activeRichard Henderson2022-07-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This new behaviour is in the ARM pseudocode function AArch64.CheckFPAdvSIMDEnabled, which applies to AArch32 via AArch32.CheckAdvSIMDOrFPEnabled when the EL to which the trap would be delivered is in AArch64 mode. Given that ARMv9 drops support for AArch32 outside EL0, the trap EL detection ought to be trivially true, but the pseudocode still contains a number of conditions, and QEMU has not yet committed to dropping A32 support for EL[12] when v9 features are present. Since the computation of SME_TRAP_NONSTREAMING is necessarily different for the two modes, we might as well preserve bits within TBFLAG_ANY and allocate separate bits within TBFLAG_A32 and TBFLAG_A64 instead. Note that DDI0616A.a has typos for bits [22:21] of LD1RO in the table of instructions illegal in streaming mode.

* target/arm: Simplify GEN_SHIFT in translate.cRichard Henderson2022-04-221-10/+8Star
| | | | | | | | | | | | | | | | | | | Instead of computing tmp1 = shift & 0xff; dest = (tmp1 > 0x1f ? 0 : value) << (tmp1 & 0x1f) use tmpd = value << (shift & 0x1f); dest = shift & 0xe0 ? 0 : tmpd; which has a flatter dependency tree. Use tcg_constant_i32 while we're at it.
