2022-06-06x86: cpu: fixup number of addressable IDs for logical processors sharing cacheIgor Mammedov
When QEMU is started with '-cpu host,host-cache-info=on', it will passthrough host's number of logical processors sharing cache and number of processor cores in the physical package. QEMU already fixes up the later to correctly reflect number of configured cores for VM, however number of logical processors sharing cache is still comes from host CPU, which confuses guest started with: -machine q35,accel=kvm \ -cpu host,host-cache-info=on,l3-cache=off \ -smp 20,sockets=2,dies=1,cores=10,threads=1 \ -numa node,nodeid=0,memdev=ram-node0 \ -numa node,nodeid=1,memdev=ram-node1 \ -numa cpu,socket-id=0,node-id=0 \ -numa cpu,socket-id=1,node-id=1 on 2 socket Xeon 4210R host with 10 cores per socket with CPUID[04H]: ... --- cache 3 --- cache type = unified cache (3) cache level = 0x3 (3) self-initializing cache level = true fully associative cache = false maximum IDs for CPUs sharing cache = 0x1f (31) maximum IDs for cores in pkg = 0xf (15) ... that doesn't match number of logical processors VM was configured with and as result RHEL 9.0 guest complains: sched: CPU #10's llc-sibling CPU #0 is not on the same node!

Accourding Intel's CPUID[EAX=04H] resulting bits 31 - 26 in EAX should be: " **** The nearest power-of-2 integer that is not smaller than (1 + EAX[31:26]) is the number of unique Core_IDs reserved for addressing different processor cores in a physical package. Core ID is a subset of bits of the initial APIC ID. " ensure that values stored in EAX[31-26] always meets this condition.

2022-06-06target/i386/tcg: Fix masking of real-mode addresses with A20 bitStephen Michael Jothen
The correct A20 masking is done if paging is enabled (protected mode) but it seems to have been forgotten in real mode. For example from the AMD64 APM Vol. 2 section 1.2.4: > If the sum of the segment base and effective address carries over into bit 20, > that bit can be optionally truncated to mimic the 20-bit address wrapping of the > 8086 processor by using the A20M# input signal to mask the A20 address bit. Most BIOSes will enable the A20 line on boot, but I found by disabling the A20 line afterwards, the correct wrapping wasn't taking place. `handle_mmu_fault' in target/i386/tcg/sysemu/excp_helper.c seems to be the culprit. In real mode, it fills the TLB with the raw unmasked address. However, for the protected mode, the `mmu_translate' function does the correct A20 masking. The fix then should be to just apply the A20 mask in the first branch of the if statement.

2022-06-03target/s390x: kvm: Honor storage keys during emulationJanis Schoetterl-Glausch
Storage key controlled protection is currently not honored when emulating instructions. If available, enable key protection for the MEM_OP ioctl, thereby enabling it for the s390_cpu_virt_mem_* functions, when using kvm. As a result, the emulation of the following instructions honors storage keys: * CLP The Synch I/O CLP command would need special handling in order to support storage keys, but is currently not supported. * CHSC Performing commands asynchronously would require special handling, but commands are currently always synchronous. * STSI * TSCH Must (and does) not change channel if terminated due to protection. * MSCH Suppressed on protection, works because fetching instruction. * SSCH Suppressed on protection, works because fetching instruction. * STSCH * STCRW Suppressed on protection, this works because no partial store is possible, because the operand cannot span multiple pages. * PCISTB * MPCIFC * STPCIFC Signed-off-by: Janis Schoetterl-Glausch <scgl@linux.ibm.com> Message-Id: <20220506153956.2217601-3-scgl@linux.ibm.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

2022-06-02target/m68k: Fix stack frame for EXCP_ILLEGALRichard Henderson
According to the M68040 Users Manual, section 8.4.1, Four word stack frame (format 0), includes Illegal Instruction. Use the correct frame format, which does not use the ADDR argument.

2022-06-02target/m68k: Fix address argument for EXCP_TRACERichard Henderson
According to the M68040 Users Manual, section 8.4.3, Six word stack frame (format 2), Trace (and others) is supposed to record the next insn in PC and the address of the trapping instruction in ADDRESS. Create gen_raise_exception_format2 to record the trapping pc in env->mmu.ar. Update m68k_interrupt_all to pass the value to do_stack_frame. Update cpu_loop to handle EXCP_TRACE.

2022-06-02target/m68k: Fix pc, c flag, and address argument for EXCP_DIV0Richard Henderson
According to the M68040 Users Manual, section 8.4.3, Six word stack frame (format 2), Zero Div (and others) is supposed to record the next insn in PC and the address of the trapping instruction in ADDRESS. While the N, Z and V flags are documented to be undefine on DIV0, the C flag is documented as always cleared. Update helper_div* to take the instruction length as an argument and use raise_exception_format2. Hoist the reset of the C flag above the division by zero check. Update m68k_interrupt_all to pass mmu.ar to do_stack_frame. Update cpu_loop to pass mmu.ar to siginfo.si_addr, as the kernel does in trap_c().

According to the M68040 Users Manual, section 8.4.3, Six word stack frame (format 2), CHK, CHK2 (and others) are supposed to record the next insn in PC and the address of the trapping instruction in ADDRESS. Create a raise_exception_format2 function to centralize recording of the trapping pc in mmu.ar, plus advancing to the next insn. Update m68k_interrupt_all to pass mmu.ar to do_stack_frame.
