2024-07-26ppc/pnv: Add a big-core mode that joins two regular coresNicholas Piggin
POWER9 and POWER10 machines come in two variants, big-core and small-core. Big-core machines are SMT8 from software's point of view, but the low level platform topology ("xscom registers and pervasive addressing"), these look more like a pair of small cores ganged together. Presently the way this is modelled is to create one SMT8 PnvCore and add special cases to xscom and pervasive for big-core mode that tries to split this into two small cores, but this is becoming too complicated to manage. A better approach is to create 2 core structures and ganging them together to look like an SMT8 core in TCG. Then the xscom and pervasive models mostly do not need to differentiate big and small core modes. This change adds initial mode bits and QEMU topology handling to split SMT8 cores into 2xSMT4 cores.

2024-07-26ppc: Add has_smt_siblings property to CPUPPCStateNicholas Piggin
The decision to branch out to a slower SMT path in instruction emulation will become a bit more complicated with the way that "big-core" topology that will be implemented in subsequent changes. Hide these details from the wider CPU emulation code with a bool has_smt_siblings flag that can be set by machine initialisation.

2024-07-26target/ppc: Add helpers to check for SMT sibling threadsNicholas Piggin
Add helpers for TCG code to determine if there are SMT siblings sharing per-core and per-lpar registers. This simplifies the callers and makes SMT register topology simpler to modify with later changes.

2024-07-26ppc: Add a core_index to CPUPPCState for SMT vCPUsNicholas Piggin
The way SMT thread siblings are matched is clunky, using hard-coded logic that checks the PIR SPR. Change that to use a new core_index variable in the CPUPPCState, where all siblings have the same core_index. CPU realize routines have flexibility in setting core/sibling topology.

2024-07-26ppc/pnv: Extend chip_pir class method to TIR as wellNicholas Piggin
The chip_pir chip class method allows the platform to set the PIR processor identification register. Extend this to a more general ID function which also allows the TIR to be set. This is in preparation for "big core", which is a more complicated topology of cores and threads. Reviewed-by: Cédric Le Goater <clg@redhat.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>

2024-07-26target/ppc: Move SPR indirect registers into PnvCoreNicholas Piggin
SPRC/SPRD were recently added to all BookS CPUs supported, but they are only tested on POWER9 and POWER10, so restrict them to those CPUs. SPR indirect scratch registers presently replicated per-CPU like SMT SPRs, but the PnvCore is a better place for them since they are restricted to P9/P10. Also add SPR indirect read access to core thread state for POWER9 since skiboot accesses that when booting to check for big-core mode. Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
2024-07-26ppc/pnv: Move timebase state into PnvCoreNicholas Piggin
The timebase state machine is per per-core state and can be driven by any thread in the core. It is currently implemented as a hack where the state is in a CPU structure and only thread 0's state is accessed by the chiptod, which limits programming the timebase side of the state machine to thread 0 of a core. Move the state out into PnvCore and share it among all threads. Reviewed-by: Harsh Prateek Bora <harshpb@linux.ibm.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>

2024-07-26target/ppc: Fix msgsnd for POWER8Nicholas Piggin
POWER8 (ISA v2.07S) introduced the doorbell facility, the msgsnd instruction behaved mostly like msgsndp, it was addressed by TIR and could only send interrupts between threads on the core. ISA v3.0 changed msgsnd to be addressed by PIR and can interrupt any thread in the system. msgsnd only implements the v3.0 semantics, which can make multi-threaded POWER8 hang when booting Linux (due to IPIs failing). This change adds v2.07 semantics. Reviewed-by: Cédric Le Goater <clg@redhat.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
2024-07-26ppc/pnv: Implement ADU access to LPC spaceNicholas Piggin
One of the functions of the ADU is indirect memory access engines that send and receive data via ADU registers. This implements the ADU LPC memory access functionality sufficiently for IBM proprietary firmware to access the UART and print characters to the serial port as it does on real hardware. This requires a linkage between adu and lpc, which allows adu to perform memory access in the lpc space.

2024-07-26ppc/pnv: Begin a more complete ADU LPC model for POWER9/10Nicholas Piggin
This implements a framework for an ADU unit model. The ADU unit actually implements XSCOM, which is the bridge between MMIO and PIB. However it also includes control and status registers and other functions that are exposed as PIB (xscom) registers. To keep things simple, pnv_xscom.c remains the XSCOM bridge implementation, and pnv_adu.c implements the ADU registers and other functions. So far, just the ADU no-op registers in the pnv_xscom.c default handler are moved over to the adu model.

2024-07-26ppc/pnv: Implement POWER9 LPC PSI serirq outputs and auto-clear functionNicholas Piggin
The POWER8 LPC ISA device irqs all get combined and reported to the line connected the PSI LPCHC irq. POWER9 changed this so only internal LPC host controller irqs use that line, and the device irqs get routed to 4 new lines connected to PSI SERIRQ0-3. POWER9 also introduced a new feature that automatically clears the irq status in the LPC host controller when EOI'ed, so software does not have to. The powernv OPAL (skiboot) firmware managed to work because the LPCHC irq handler scanned all LPC irqs and handled those including clearing status even on POWER9 systems. So LPC irqs worked despite OPAL thinking it was running in POWER9 mode. After this change, UART interrupts show up on serirq1 which is where OPAL routes them to: cat /proc/interrupts ... 20: 0 XIVE-IRQ 1048563 Level opal-psi#0:lpchc ... 25: 34 XIVE-IRQ 1048568 Level opal-psi#0:lpc_serirq_mux1 Whereas they previously turn up on lpchc.

2024-07-26ppc/pnv: Fix loss of LPC SERIRQ interruptsGlenn Miles
The LPC HC irq status register bits are set when an LPC IRQSER input is asserted. These irq status bits drive the PSI irq to the CPU interrupt controller. The LPC HC irq status bits are cleared by software writing to the register with 1's for the bits to clear. Existing register write was clearing the irq status bits even when the input was asserted, this results in interrupts being lost. This fix changes the behavior to keep track of the device IRQ status in internal state that is separate from the irq status register, and only allowing the irq status bits to be cleared if the associated input is not asserted.

2024-07-26target/ppc: handle vcpu hotplug failure gracefullyHarsh Prateek Bora
On ppc64, the PowerVM hypervisor runs with limited memory and a VCPU creation during hotplug may fail during kvm_ioctl for KVM_CREATE_VCPU, leading to termination of guest since errp is set to &error_fatal while calling kvm_init_vcpu. This unexpected behaviour can be avoided by pre-creating and parking vcpu on success or return error otherwise. This enables graceful error delivery for any vcpu hotplug failures while the guest can keep running. Also introducing KVM AccelCPUClass to init cpu_target_realize for kvm. Tested OK by repeatedly doing a hotplug/unplug of vcpus as below: #virsh setvcpus hotplug 40 #virsh setvcpus hotplug 70 error: internal error: unable to execute QEMU command 'device_add': kvmppc_cpu_realize: vcpu hotplug failed with -12 Signed-off by: Harsh Prateek Bora <harshpb@linux.ibm.com> Reported-by: Anushree Mathur <anushree.mathur@linux.vnet.ibm.com> Suggested-by: Shivaprasad G Bhat <sbhat@linux.ibm.com> Suggested-by: Vaibhav Jain <vaibhav@linux.ibm.com> Tested-by: Anushree Mathur <anushree.mathur@linux.vnet.ibm.com> Reviewed-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>

aio_context_set_thread_pool_params() takes two int64_t arguments to set the minimum and maximum number of threads in the pool. We do some bounds checking on these, but we don't catch the case where the inputs are negative. This means that later in the function when we assign these inputs to the AioContext::thread_pool_min and ::thread_pool_max fields, which are of type int, the values might overflow the smaller type.

bsd-user: Misc changes for 9.1 (I hope) V2: Add missing bsd-user/aarch64/target.h This patch series includes two main sets of patches. To make it simple to review, I've included the changes from my student which the later changes depend on. I've included a change from Jessica and Doug as well. I've reviewed them, but more eyes never hurt. I've also included a number of 'touch up' patches needed either to get the aarch64 building, or to implmement suggestions from prior review cycles. The main one is what's charitably described as a kludge: force aarch64 to use 4k pages. The qemu-project (and blitz branch) hasn't had the necessary changes to bsd-user needed to support variable page size. Sorry this is so late...

2024-07-24crypto: propagate errors from TLS session I/O callbacksDaniel P. Berrangé
GNUTLS doesn't know how to perform I/O on anything other than plain FDs, so the TLS session provides it with some I/O callbacks. The GNUTLS API design requires these callbacks to return a unix errno value, which means we're currently loosing the useful QEMU "Error" object. This changes the I/O callbacks in QEMU to stash the "Error" object in the QCryptoTLSSession class, and fetch it when seeing an I/O error returned from GNUTLS, thus preserving useful error messages.

As noted in commit d47b83b118 ("tests: add migration tests of TLS with x509 credentials"), having GnuTLS without Libtasn1 is a valid configuration, so do not require Libtasn1, to avoid: Dependency gnutls found: YES 3.7.1 (cached) Run-time dependency libtasn1 found: NO (tried pkgconfig) ../meson.build:1914:10: ERROR: Dependency "libtasn1" not found, tried pkgconfig Fixes: ba7ed407e6 ("configure, meson: convert libtasn1 detection to meson") Reviewed-by: Daniel P.
