First arm pullreq for 7.1. The bulk of this is the qemu_split_irq removal. I have enough stuff in my to-review queue that I expect to do another pullreq early next week, but 31 patches is enough to not hang on to. thanks -- PMM The following changes since commit 9c125d17e9402c232c46610802e5931b3639d77b: Merge tag 'pull-tcg-20220420' of https://gitlab.com/rth7680/qemu into staging (2022-04-20 16:43:11 -0700) are available in the Git repository at: https://git.linaro.org/people/pmaydell/qemu-arm.git tags/pull-target-arm-20220421 for you to fetch changes up to 5b415dd61bdbf61fb4be0e9f1a7172b8bce682c6: hw/arm: Use bit fields for NPCM7XX PWRON STRAPs (2022-04-21 11:37:05 +0100) ---------------------------------------------------------------- target-arm queue: * hw/arm/virt: Check for attempt to use TrustZone with KVM or HVF * versal: Add the Cortex-R5s in the Real-Time Processing Unit (RPU) subsystem * versal: model enough of the Clock/Reset Low-power domain (CRL) to allow control of the Cortex-R5s * xlnx-zynqmp: Connect 4 TTC timers * exynos4210: Refactor GIC/combiner code to stop using qemu_split_irq * realview: replace 'qemu_split_irq' with 'TYPE_SPLIT_IRQ' * stellaris: replace 'qemu_split_irq' with 'TYPE_SPLIT_IRQ' * hw/core/irq: remove unused 'qemu_irq_split' function * npcm7xx: use symbolic constants for PWRON STRAP bit fields * virt: document impact of gic-version on max CPUs ---------------------------------------------------------------- Edgar E.

(This will result in those interrupts simply being lost, not in a QEMU crash.) I don't have a reliable datasheet for this SoC, but since we do wire up one interrupt line in this category (the HDMI I2C device on interrupt 16,1), this seems like it must be a bug in the existing QEMU code. Fill in the irq_table[] entries where we're not splitting the IRQ to both the internal combiner and the external GIC with the IRQ line of the internal combiner. (That is, these IRQ lines go to just one device, not multiple.) This bug didn't have any visible guest effects because the only implemented device that was affected was the HDMI I2C controller, and we never connect any I2C devices to that bus.

This means that we will connect multiple IRQs up to the same external GIC input, which is not permitted. We do the same thing in the code in exynos4210_init_board_irqs() because the conditionals selecting an irq_id in the first loop match multiple interrupt IDs. Overall we do this for interrupt IDs (1, 4), (12, 4), (35, 4), (51, 4), (53, 4) for EXT_GIC_ID_MCT_G0 and (1, 5), (12, 5), (35, 5), (51, 5), (53, 5) for EXT_GIC_ID_MCT_G1 These correspond to the cases for the multi-core timer that we are wiring up to multiple inputs on the combiner in exynos4210_combiner_get_gpioin(). That code already deals with all these interrupt IDs being the same input source, so we don't need to connect the external GIC interrupt for any of them except the first (1, 4) and (1, 5). Remove the array entries and conditionals which were incorrectly causing us to wire up extra lines. This bug didn't cause any visible effects, because we only connect up a device to the "primary" ID values (1, 4) and (1, 5), so the extra lines would never be set to a level.

The function exynos4210_combiner_get_gpioin() splits some of the combiner input lines further to connect them to multiple different inputs on the combiner. Because (unlike qemu_irq_split()) the TYPE_SPLIT_IRQ device has a configurable number of outputs, we can do all this in one place, by making exynos4210_init_board_irqs() add extra outputs to the splitter device when it must be connected to more than one input on each combiner. We do this with a new data structure, the combinermap, which is an array each of whose elements is a list of the interrupt IDs on the combiner which must be tied together. As we loop through each interrupt ID, if we find that it is the first one in one of these lists, we configure the splitter device with eonugh extra outputs and wire them up to the other interrupt IDs in the list. Conveniently, for all the cases where this is necessary, the lowest-numbered interrupt ID in each group is in the range of the external combiner, so we only need to code for this in the first of the two loops in exynos4210_init_board_irqs(). The old code in exynos4210_combiner_get_gpioin() which is being deleted here had several problems which don't exist in the new code in its handling of the multi-core timer interrupts: (1) the case labels specified bits 4 ... 8, but bit '8' doesn't exist; these should have been 4 ... 7 (2) it used the input irq[EXYNOS4210_COMBINER_GET_IRQ_NUM(1, bit + 4)] multiple times as the input of several different splitters, which isn't allowed (3) in an apparent cut-and-paste error, the cases for all the multi-core timer inputs used "bit + 4" even though the bit range for the case was (intended to be) 4 ... 7, which meant it was looking at non-existent bits 8 ... 11. None of these exist in the new code.

Now that the combiner objects are easily accessible as s->int_combiner and s->ext_combiner we can make the connections directly from one device to the other without going via these arrays. Since these are the only two remaining elements of Exynos4210Irq, we can remove that struct entirely.

This made sense in the original design where the only way for a clock's frequency to change if it had a source clock was when that source clock changed. However, we subsequently added multiplier/divider support, but didn't look at what that meant for propagation. If a clock-management device changes the multiplier or divider value on a clock, it needs to propagate that change down to child clocks, even if the clock has a source clock set. So the assertion is now incorrect. Remove the assertion.

FEAT_Spec_FPACC means that the speculative use of pointers processed by a PAC Authentication is not materially different in terms of the impact on cached microarchitectural state (caches, TLBs, etc) between passing and failing of the PAC Authentication. QEMU doesn't do speculative execution, so we can advertise this feature.

The way this is done includes some complication resulting from how this was originally a fixed value with no QOM property. Clean it up: * always set cpu->gt_cntfrq_hz to some sensible value, whether the CPU has the generic timer or not, and whether it's system or user-only emulation * this means we can always use gt_cntfrq_hz, and never need the old GTIMER_SCALE define * set the default value in exactly one place, in the realize fn The aim here is to pave the way for handling the ARMv8.6 requirement that the generic timer frequency is always 1GHz. We're going to do that by having old CPU types keep their legacy-in-QEMU behaviour and having the default for any new CPU types be a 1GHz rather han 62.5MHz cntfrq, so we want the point where the default is decided to be in one place, and in code, not in a DEFINE_PROP_UINT64() initializer.

For older versions of the TF-A firmware that sbsa-ref runs, the frequency of the generic timer is hardcoded into the firmware, and so if the CPU actually has a different frequency then timers in the guest will be set incorrectly. The default frequency used by the 'max' CPU is about to change, so make the sbsa-ref board force the CPU frequency to the value which the firmware expects. Newer versions of TF-A will read the frequency from the CPU's CNTFRQ_EL0 register: https://github.com/ARM-software/arm-trusted-firmware/commit/4c77fac98dac0bebc63798aae9101ac865b87148 so in the longer term we could make this board use the 1GHz frequency.

In real hardware, this watchdog is supposed to be driven from the system counter, which also drives the CPU generic timers. Newer CPU types (in particular from Armv8.6) should have a CPU generic timer frequency of 1GHz, so we can't leave the watchdog on the old QEMU default of 62.5GHz. Make the frequency a QOM property so it can be set by the board, and have our only board that uses this device set that frequency to the same value it sets the CPU frequency.

In Armv8.6, the architecture standardized this frequency to 1GHz. Because there is no ID register feature field that indicates whether a CPU is v8.6 or that it ought to have this counter frequency, we implement this by changing our default CNTFRQ value for all CPUs, with exceptions for backwards compatibility: * CPU types which we already implement will retain the old default value. None of these are v8.6 CPUs, so this is architecturally OK. * CPUs used in versioned machine types with a version of 9.0 or earlier will retain the old default value. The upshot is that the only CPU type that changes is 'max'; but any new type we add in future (whether v8.6 or not) will also get the new 1GHz default. It remains the case that the machine model can override the default value via the 'cntfrq' QOM property (regardless of the CPU type).
