2022-07-11linux-user/aarch64: Do not allow duplicate or short sve recordsRichard Henderson
In parse_user_sigframe, the kernel rejects duplicate sve records, or records that are smaller than the header. We were silently allowing these cases to pass, dropping the record.

2022-07-11target/arm: Trap non-streaming usage when Streaming SVE is activeRichard Henderson
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.

2022-07-08build: try both native and cross compilersPaolo Bonzini
Configure is trying to fall back on cross compilers for targets that can have bi-arch or bi-endian toolchains, but there are many corner cases where just checking the name can go wrong. For example, the RHEL ppc64le compiler is bi-arch and bi-endian, but multilibs are disabled. Therefore it cannot be used to build 32-bit hosted binaries like the linux-user TCG tests. Trying the cross compiler first also does not work, and an example for this is also ppc64le. The powerpc64-linux-gnu-gcc binary from the cross-gcc package is theoretically multilib-friendly, but it cannot find the CRT files on a ppc64le host, because they are not in the .../le multilib subdirectory. This can be fixed by testing both the native compiler and the cross compiler, and proceeding with the first one that works. To do this, move the compiler usability check from the tests/tcg snippet to inside probe_target_compiler and, while at it, restrict the softmmu emulation target to basically a test for the presence of libgcc.

2022-07-07target/arm: Fix qemu-system-arm handling of LPAE block descriptors for highmemPeter Maydell
In commit 39a1fd25287f5d we fixed a bug in the handling of LPAE block descriptors where we weren't correctly zeroing out some RES0 bits. However this fix has a bug because the calculation of the mask is done at the wrong width: in descaddr &= ~(page_size - 1); page_size is a target_ulong, so in the 'qemu-system-arm' binary it is only 32 bits, and the effect is that we always zero out the top 32 bits of the calculated address. Fix the calculation by forcing the mask to be calculated with the same type as descaddr. This only affects 32-bit CPUs which support LPAE (e.g. cortex-a15) when used on board models which put RAM or devices above the 4GB mark and when the 'qemu-system-arm' executable is being used. It was also masked in 7.0 by the main bug reported in https://gitlab.com/qemu-project/qemu/-/issues/1078 where the virt board incorrectly does not enable 'highmem' for 32-bit CPUs. The workaround is to use 'qemu-system-aarch64' with the same command line.

2022-07-07target/arm: Correctly implement Feat_DoubleLockPeter Maydell
The architecture defines the OS DoubleLock as a register which (similarly to the OS Lock) suppresses debug events for use in CPU powerdown sequences. This functionality is required in Arm v7 and v8.0; from v8.2 it becomes optional and in v9 it must not be implemented. Currently in QEMU we implement the OSDLR_EL1 register as a NOP. This is wrong both for the "feature implemented" and the "feature not implemented" cases: if the feature is implemented then the DLK bit should read as written and cause suppression of debug exceptions, and if it is not implemented then the bit must be RAZ/WI.

2022-07-07target/arm: Implement AArch32 DBGDEVID, DBGDEVID1, DBGDEVID2Peter Maydell
Starting with v7 of the debug architecture, there are three extra ID registers that add information on top of that provided in DBGDIDR. These are DBGDEVID, DBGDEVID1 and DBGDEVID2. In the v7 debug architecture, DBGDEVID is optional, present only of DBGDIDR.DEVID_imp is set. In v7.1 all three must be present. Implement the missing registers. Note that we only need to set the values in the ARMISARegisters struct for the CPUs Cortex-A7, A15, A53, A57 and A72 (plus the 32-bit 'max' which uses the Cortex-A53 values): earlier CPUs didn't implement v7 of the architecture, and our other 64-bit CPUs (Cortex-A76, Neoverse-N1 and A64fx) don't have AArch32 support at EL1.
