2023-11-06target/hppa: Always report one page to tlb_set_pageRichard Henderson
No need to trigger the large_page_mask code unnecessarily. Drop the now unused HPPATLBEntry.page_size field. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-11-06target/hppa: Use IntervalTreeNode in HPPATLBEntryRichard Henderson
Replace the va_b and va_b fields with the interval tree node. The actual interval tree is not yet used. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Rename to CamelCase per coding style. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-11-06target/hppa: Include PSW_P in tb flags and mmu indexRichard Henderson
Use a separate mmu index for PSW_P enabled vs disabled. This means we can elide the tlb flush in cpu_hppa_put_psw when PSW_P changes. This turns out to be the majority of all tlb flushes. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

git://git.infradead.org/users/dwmw2/qemu into staging Bugfixes for emulated Xen support Selected bugfixes for mainline and stable, especially to the per-vCPU local APIC vector delivery mode for event channel notifications, which was broken in a number of ways. The xen-block driver has been defaulting to the wrong protocol for x86 guest, and this fixes that — which is technically an incompatible change but I'm fairly sure nobody relies on the broken behaviour (and in production I *have* seen guests which rely on the correct behaviour, which now matches the blkback driver in the Linux kernel).

2023-11-07target/riscv: Add "pmu-mask" property to replace "pmu-num"Rob Bradford
Using a mask instead of the number of PMU devices supports the accurate emulation of platforms that have a discontinuous set of PMU counters. The "pmu-num" property now generates a warning when used by the user on the command line. Rather than storing the value for "pmu-num" convert it directly to the mask if it is specified (overwriting the default "pmu-mask" value) likewise the value is calculated from the mask if the property value is obtained. In the unusual situation that both "pmu-mask" and "pmu-num" are provided then then the order on the command line determines which takes precedence (later overwriting earlier.)

2023-11-07hw/ssi: ibex_spi_host: Clear the interrupt even if disabledAlistair Francis
We currently don't clear the interrupts if they are disabled. This means that if an interrupt occurs and the guest disables interrupts the QEMU IRQ will remain high. This doesn't immediately affect guests, but if the guest re-enables interrupts it's possible that we will miss an interrupt as it always remains set. Let's update the logic to always call qemu_set_irq() even if the interrupts are disabled to ensure we set the level low. The level will never be high unless interrupts are enabled, so we won't generate interrupts when we shouldn't.

2023-11-07target/riscv: add zihpm extension flag for TCGDaniel Henrique Barboza
zihpm is the Hardware Performance Counters extension described in chapter 12 of the unprivileged spec. It describes support for 29 unprivileged performance counters, hpmcounter3-hpmcounter31. As with zicntr, QEMU already implements zihpm before it was even an extension. zihpm is also part of the RVA22 profile, so add it to QEMU to complement the future profile implementation. Default it to 'true' for all existing CPUs since it was always present in the code. As for disabling it, there is already code in place in target/riscv/csr.c in all predicates for these counters (ctr() and mctr()) that disables them if cpu->cfg.pmu_num is zero. Thus, setting cpu->cfg.pmu_num to zero if 'zihpm=false' is enough to disable the extension. Set cpu->pmu_avail_ctrs mask to zero as well since this is also checked to verify if the counters exist.

2023-11-07target/riscv: add zicntr extension flag for TCGDaniel Henrique Barboza
zicntr is the Base Counters and Timers extension described in chapter 12 of the unprivileged spec. It describes support for RDCYCLE, RDTIME and RDINSTRET. QEMU already implements it in TCG way before it was a discrete extension. zicntr is part of the RVA22 profile, so let's add it to QEMU to make the future profile implementation flag complete. Given than it represents an already existing feature, default it to 'true' for all CPUs. For TCG, we need a way to disable zicntr if the user wants to. This is done by restricting access to the CYCLE, TIME, and INSTRET counters via the 'ctr()' predicate when we're about to access them. Disabling zicntr happens via the command line or if its dependency, zicsr, happens to be disabled. We'll check for zicsr during realize() and, in case it's absent, disable zicntr. However, if the user was explicit about having zicntr support, error out instead of disabling it.

Use the recently added riscv_cpu_accelerator_compatible() to filter unavailable CPUs for a given accelerator. At this moment this is the case for a QEMU built with KVM and TCG support querying a binary running with TCG: qemu-system-riscv64 -S -M virt,accel=tcg -display none -qmp tcp:localhost:1234,server,wait=off ./qemu/scripts/qmp/qmp-shell localhost:1234 (QEMU) query-cpu-model-expansion type=full model={"name":"host"} {"error": {"class": "GenericError", "desc": "'host' CPU not available with tcg"}} Signed-off-by: Daniel Henrique Barboza <dbarboza@ventanamicro.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-ID: <20231018195638.211151-7-dbarboza@ventanamicro.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>
2023-11-07target/riscv: add riscv_cpu_accelerator_compatible()Daniel Henrique Barboza
Add an API to check if a given CPU is compatible with the current accelerator. This will allow query-cpu-model-expansion to work properly in conditions where QEMU supports both accelerators (TCG and KVM), QEMU is then launched using TCG, and the API requests information about a KVM only CPU (e.g. 'host' CPU). KVM doesn't have such restrictions and, at least in theory, all CPUs models should work with KVM. We will revisit this API in case we decide to restrict the amount of KVM CPUs we support.

2023-11-07target/riscv: handle custom props in qmp_query_cpu_model_expansionDaniel Henrique Barboza
Callers can add 'props' when querying for a cpu model expansion to see if a given CPU model supports a certain criteria, and what's the resulting CPU object. If we have 'props' to handle, gather it in a QDict and use the new riscv_cpuobj_validate_qdict_in() helper to validate it. This helper will add the custom properties in the CPU object and validate it using riscv_cpu_finalize_features(). Users will be aware of validation errors if any occur, if not a CPU object with 'props' will be returned. Here's an example with the veyron-v1 vendor CPU. Disabling vendor CPU extensions is allowed, assuming the final config is valid. Disabling 'smstateen' is a valid expansion: (QEMU) query-cpu-model-expansion type=full model={"name":"veyron-v1","props":{"smstateen":false}} {"return": {"model": {"name": "veyron-v1", "props": {"zicond": false, ..., "smstateen": false, ...} But enabling extensions isn't allowed for vendor CPUs. E.g. enabling 'V' for the veyron-v1 CPU isn't allowed: (QEMU) query-cpu-model-expansion type=full model={"name":"veyron-v1","props":{"v":true}} {"error": {"class": "GenericError", "desc": "'veyron-v1' CPU does not allow enabling extensions"}} Signed-off-by: Daniel Henrique Barboza <dbarboza@ventanamicro.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-ID: <20231018195638.211151-5-dbarboza@ventanamicro.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>
