2024-12-11target/ppc: Use env->fp_status in helper_compute_fprf functionsPeter Maydell1-2/+1
In the helper_compute_fprf functions, we pass a dummy float_status in to the is_signaling_nan() function. This is unnecessary, because we have convenient access to the CPU env pointer here and that is already set up with the correct values for the snan_bit_is_one and no_signaling_nans config settings. is_signaling_nan() doesn't ever update the fp_status with any exception flags, so there is no reason not to use env->fp_status here.

2024-11-27ppc/pnv: Fix direct controls quiesceNicholas Piggin1-0/+1
powernv CPUs have a set of control registers that can stop, start, and do other things to control a thread's execution. Using this interface to stop a thread puts it into a particular state that can be queried, and is distinguishable from other things that might stop the CPU (e.g., going idle, or being debugged via gdb, or stopped by the monitor). Add a new flag that can speficially distinguish this state where it is stopped with control registers. This solves some hangs when rebooting powernv machines when skiboot is modified to allow QEMU to use the CPU control facility (that uses controls to bring all secondaries to a known state).

2024-11-27target/ppc: Fix non-maskable interrupt while haltedNicholas Piggin1-0/+7
The ppc (pnv and spapr) NMI injection code does not go through the asynchronous interrupt path and set a bit in env->pending_interrupts and raise an interrupt request that the cpu_exec() loop can see. Instead it injects the exception directly into registers. This can lead to cpu_exec() missing that the thread has work to do, if a NMI is injected while it was idle. Fix this by clearing halted when injecting the interrupt. Probably NMI injection should be reworked to use the interrupt request interface, but this seems to work as a minimal fix.

2024-11-04target/ppc: Fix regression due to Power10 and Power11 having same PCRAditya Gupta1-0/+4
Power11 has the same PCR (Processor Compatibility Register) value, as Power10. Due to this, QEMU considers Power11 as a valid compat-mode for Power10, ie. earlier it was possible to run QEMU with '-M pseries,max-compat-mode=power11 --cpu power10' Same PCR also introduced a regression where `-M pseries --cpu power10` boots as Power11 (ie. logical PVR is of Power11, even though PVR is Power10). The regression was due to 'do_client_architecture_support' checking for valid compat modes and finding Power11 to be a valid compat mode for Power10 (it happens even without passing 'max-compat-mode' explicitly). Fix compat-mode issue and regression, by ensuring a future Power processor (with a higher logical_pvr value, eg. P11) cannot be valid compat-mode for an older Power processor (eg.

The serirq routing table is split over two registers, the calculation for the high irqs in the second register did not subtract the irq offset. This was spotted by Coverity as a shift-by-negative. Fix this and change the open-coded shifting and masking to use extract32() function so it's less error-prone. This went unnoticed because irqs >= 14 are not used in a standard QEMU/OPAL boot, changing the first QEMU serial-isa irq to 14 to test does demonstrate serial irqs aren't received, and that this change fixes that.

divdu (without a dot) sometimes updates cr0, even though it shouldn't. The reason is that gen_op_arith_divd() checks Rc(ctx->opcode), which is not initialized.

There already was a similar issue fixed in commit 86e6202a57b1 ("target/ppc: Make divw[u] handler method decodetree compatible.").

2024-09-22target/ppc: Fix lxvx/stxvx facility checkFabiano Rosas1-1/+1
The XT check for the lxvx/stxvx instructions is currently inverted. This was introduced during the move to decodetree. >From the ISA: Chapter 7. Vector-Scalar Extension Facility Load VSX Vector Indexed X-form lxvx XT,RA,RB if TX=0 & MSR.VSX=0 then VSX_Unavailable() if TX=1 & MSR.VEC=0 then Vector_Unavailable() ... Let XT be the value 32×TX + T. The code currently does the opposite: if (paired || a->rt >= 32) { REQUIRE_VSX(ctx); } else { REQUIRE_VECTOR(ctx); } This was already fixed for lxv/stxv at commit "2cc0e449d1 (target/ppc: Fix lxv/stxv MSR facility check)", but the indexed forms were missed.

2024-09-03target/ppc: Fix migration of CPUs with TLB_EMB TLB typeArman Nabiev1-1/+1
In vmstate_tlbemb a cut-and-paste error meant we gave this vmstate subsection the same "cpu/tlb6xx" name as the vmstate_tlb6xx subsection. This breaks migration load for any CPU using the TLB_EMB CPU type, because when we see the "tlb6xx" name in the incoming data we try to interpret it as a vmstate_tlb6xx subsection, which it isn't the right format for: $ qemu-system-ppc -drive if=none,format=qcow2,file=/home/petmay01/test-images/virt/dummy.qcow2 -monitor stdio -M bamboo QEMU 9.0.92 monitor - type 'help' for more information (qemu) savevm foo (qemu) loadvm foo Missing section footer for cpu Error: Error -22 while loading VM state Correct the incorrect vmstate section name. Since migration for these CPU types was completely broken before, we don't need to care that this is a migration compatibility break. This affects the PPC 405, 440, 460 and e200 CPU families.
