CPUID leaf 7 was grouped together with SGX leaf 0x12 by commit b9edbadefb9e ("i386: Propagate SGX CPUID sub-leafs to KVM") by mistake. SGX leaf 0x12 has its specific logic to check if subleaf (starting from 2) is valid or not by checking the bit 0:3 of corresponding EAX is 1 or not. Leaf 7 follows the logic that EAX of subleaf 0 enumerates the maximum valid subleaf.

2024-02-15target/arm: Allow access to SPSR_hyp from hyp modePeter Maydell
Architecturally, the AArch32 MSR/MRS to/from banked register instructions are UNPREDICTABLE for attempts to access a banked register that the guest could access in a more direct way (e.g. using this insn to access r8_fiq when already in FIQ mode). QEMU has chosen to UNDEF on all of these. However, for the case of accessing SPSR_hyp from hyp mode, it turns out that real hardware permits this, with the same effect as if the guest had directly written to SPSR. Further, there is some guest code out there that assumes it can do this, because it happens to work on hardware: an example Cortex-R52 startup code fragment uses this, and it got copied into various other places, including Zephyr. Zephyr was fixed to not use this: https://github.com/zephyrproject-rtos/zephyr/issues/47330 but other examples are still out there, like the selftest binary for the MPS3-AN536. For convenience of being able to run guest code, permit this UNPREDICTABLE access instead of UNDEFing it.

2024-02-15target/arm: Use new CBAR encoding for all v8 CPUs, not all aarch64 CPUsPeter Maydell
We support two different encodings for the AArch32 IMPDEF CBAR register -- older cores like the Cortex A9, A7, A15 have this at 4, c15, c0, 0; newer cores like the Cortex A35, A53, A57 and A72 have it at 1 c15 c0 0. When we implemented this we picked which encoding to use based on whether the CPU set ARM_FEATURE_AARCH64. However this isn't right for three cases: * the qemu-system-arm 'max' CPU, which is supposed to be a variant on a Cortex-A57; it ought to use the same encoding the A57 does and which the AArch64 'max' exposes to AArch32 guest code * the Cortex-R52, which is AArch32-only but has the CBAR at the newer encoding (and where we incorrectly are not yet setting ARM_FEATURE_CBAR_RO anyway) * any possible future support for other v8 AArch32 only CPUs, or for supporting "boot the CPU into AArch32 mode" on our existing cores like the A57 etc Make the decision of the encoding be based on whether the CPU implements the ARM_FEATURE_V8 flag instead. This changes the behaviour only for the qemu-system-arm '-cpu max'. We don't expect anybody to be relying on the old behaviour because: * it's not what the real hardware Cortex-A57 does (and that's what our ID register claims we are) * we don't implement the memory-mapped GICv3 support which is the only thing that exists at the peripheral base address pointed to by the register Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20240206132931.38376-2-peter.maydell@linaro.org

Avoid the assertion by not calling arm_mdcr_el2_eff() before we have done the early return for "PMU not present". This fixes an assertion failure if you try to do a loadvm or savevm for an M-profile board.

2024-02-15target/arm: Adjust and validate mtedesc sizem1Richard Henderson
When we added SVE_MTEDESC_SHIFT, we effectively limited the maximum size of MTEDESC. Adjust SIZEM1 to consume the remaining bits (32 - 10 - 5 - 12 == 5). Assert that the data to be stored fits within the field (expecting 8 * 4 - 1 == 31, exact fit).

2024-02-11target/hppa: PDC_BTLB_INFO uses 32-bit intsHelge Deller
The BTLB helper function stores the BTLB info (four 32-bit ints) into the memory of the guest. They are only available when emulating a 32-bit CPU in the guest, so use "uint32_t" instead of "target_ulong" here.

2024-02-11target/hppa: Allow read-access to PSW with rsm 0,reg instructionHelge Deller
HP-UX 11 and HP ODE tools use the "rsm 0,%reg" instruction in not priviledged code paths to get the current PSW flags. The constant 0 means that no bits of the PSW shall be reset, so this is effectively a read-only access to the PSW. Allow this read-only access even for not privileged code.

We still lack implementation for some registers, so do not yet enable sending HPMCs. Having this hunk here now nevertheless helps for the further development, so that it can easily be enabled later on. Signed-off-by: Helge Deller <deller@gmx.de>
2024-02-11target/hppa: Add "diag 0x101" for console output supportHelge Deller
For debugging purposes at the early stage of the bootup process, the SeaBIOS-hppa firmware sometimes needs to output characters to the serial console. Note that the serial console is the default output method for parisc machines. At this stage PCI busses and other devices haven't been initialized yet. So, SeaBIOS-hppa will not be able to find the correct I/O ports for the serial ports yet. Instead, add an emulation for the "diag 0x101" opcode to assist here. Without any other dependencies, SeaBIOS-hppa can then load the character to be printed in register %r26 and issue the diag assembly instruction. The qemu diag_console_output() helper function will then print that character to the first serial port.

2024-02-09target/riscv: add rv32i, rv32e and rv64e CPUsDaniel Henrique Barboza
A bare bones 32 bit RVI CPU, rv32i, will make users lives easier when a full customized 32 bit CPU is desired, and users won't need to disable defaults by hand as they would with the rv32 CPU. [1] has an example of a situation that would be avoided with rv32i. In fact, add bare bones CPUs for RVE as well. Trying to use RVE in QEMU requires one to disable every single default extension, including RVI, and then add the desirable extension set. Adding rv32e/rv64e makes it more pleasant to use embedded CPUs in QEMU.
