2023-02-27i386: Add new CPU model SapphireRapidsWang, Lei
The new CPU model mostly inherits features from Icelake-Server, while adding new features: - AMX (Advance Matrix eXtensions) - Bus Lock Debug Exception and new instructions: - AVX VNNI (Vector Neural Network Instruction): - VPDPBUS: Multiply and Add Unsigned and Signed Bytes - VPDPBUSDS: Multiply and Add Unsigned and Signed Bytes with Saturation - VPDPWSSD: Multiply and Add Signed Word Integers - VPDPWSSDS: Multiply and Add Signed Integers with Saturation - FP16: Replicates existing AVX512 computational SP (FP32) instructions using FP16 instead of FP32 for ~2X performance gain - SERIALIZE: Provide software with a simple way to force the processor to complete all modifications, faster, allowed in all privilege levels and not causing an unconditional VM exit - TSX Suspend Load Address Tracking: Allows programmers to choose which memory accesses do not need to be tracked in the TSX read set - AVX512_BF16: Vector Neural Network Instructions supporting BFLOAT16 inputs and conversion instructions from IEEE single precision - fast zero-length MOVSB (KVM doesn't support yet) - fast short STOSB (KVM doesn't support yet) - fast short CMPSB, SCASB (KVM doesn't support yet) Features that may be added in future versions: - CET (virtualization support hasn't been merged) Signed-off-by: Wang, Lei <lei4.wang@intel.com> Reviewed-by: Robert Hoo <robert.hu@linux.intel.com> Message-Id: <20220812055751.14553-1-lei4.wang@intel.com> Reviewed-by: Xiaoyao Li <xiaoyao.li@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2023-02-27target/s390x/arch_dump: Fix memory corruption in s390x_write_elf64_notes()Thomas Huth
"note_size" can be smaller than sizeof(note), so unconditionally calling memset(notep, 0, sizeof(note)) could cause a memory corruption here in case notep has been allocated dynamically, thus let's use note_size as length argument for memset() instead.

2023-02-21target/i386/gdbstub: Fix a bug about order of FPU stack in 'g' packets.TaiseiIto
Before this commit, when GDB attached an OS working on QEMU, order of FPU stack registers printed by GDB command 'info float' was wrong. There was a bug causing the problem in 'g' packets sent by QEMU to GDB. The packets have values of registers of machine emulated by QEMU containing FPU stack registers. There are 2 ways to specify a x87 FPU stack register. The first is specifying by absolute indexed register names (R0, ..., R7). The second is specifying by stack top relative indexed register names (ST0, ..., ST7). Values of the FPU stack registers should be located in 'g' packet and be ordered by the relative index. But QEMU had located these registers ordered by the absolute index. After this commit, when QEMU reads registers to make a 'g' packet, QEMU specifies FPU stack registers by the relative index. Then, the registers are ordered correctly in the packet. As a result, GDB, the packet receiver, can print FPU stack registers in the correct order.
