Previously, we would avoid setting CPU_INTERRUPT_HARD when interrupts are disabled at a particular point in time, instead queuing the value into cpu->irq_pending. This is more complicated than required. Instead, set CPU_INTERRUPT_HARD any time there is a pending interrupt, and exclusively check for interrupts disabled in nios2_cpu_exec_interrupt.

2022-03-03hw/nvme: 64-bit pi supportNaveen Nagar7-98/+608
This adds support for one possible new protection information format introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard and 48-bit reference tag. This version does not support storage tags. Like the CRC16 support already present, this uses a software implementation of CRC64 (so it is naturally pretty slow). But its good enough for verification purposes. This may go nicely hand-in-hand with the support that Keith submitted for the Linux kernel[1].

We extend virt machine to emulate AIA APLIC devices only when "aia=aplic" parameter is passed along with machine name in QEMU command-line. When "aia=none" or not specified then we fallback to original PLIC device emulation.

2022-03-03target/riscv: fix inverted checks for ext_zb[abcs]Philipp Tomsich1-4/+4
While changing to the use of cfg_ptr, the conditions for REQUIRE_ZB[ABCS] inadvertently became inverted and slipped through the initial testing (which used RV64GC_XVentanaCondOps as a target). This fixes the regression. Tested against SPEC2017 w/ GCC 12 (prerelease) for RV64GC_zba_zbb_zbc_zbs.

2022-03-02ui/cocoa.m: Remove unnecessary NSAutoreleasePoolsPeter Maydell1-6/+0
In commit 6e657e64cdc478 in 2013 we added some autorelease pools to deal with complaints from macOS when we made calls into Cocoa from threads that didn't have automatically created autorelease pools. Later on, macOS got stricter about forbidding cross-thread Cocoa calls, and in commit 5588840ff77800e839d8 we restructured the code to avoid them. This left the autorelease pool creation in several functions without any purpose; delete it. We still need the pool in cocoa_refresh() for the clipboard related code which is called directly there.

2022-03-02ui/cocoa.m: Fix updateUIInfo threading issuesPeter Maydell1-3/+22
The updateUIInfo method makes Cocoa API calls. It also calls back into QEMU functions like dpy_set_ui_info(). To do this safely, we need to follow two rules: * Cocoa API calls are made on the Cocoa UI thread * When calling back into QEMU we must hold the iothread lock Fix the places where we got this wrong, by taking the iothread lock while executing updateUIInfo, and moving the call in cocoa_switch() inside the dispatch_async block. Some of the Cocoa UI methods which call updateUIInfo are invoked as part of the initial application startup, while we're still doing the little cross-thread dance described in the comment just above call_qemu_main(). This meant they were calling back into the QEMU UI layer before we'd actually finished initializing our display and registered the DisplayChangeListener, which isn't really valid. Once updateUIInfo takes the iothread lock, we no longer get away with this, because during this startup phase the iothread lock is held by the QEMU main-loop thread which is waiting for us to finish our display initialization. So we must suppress updateUIInfo until applicationDidFinishLaunching allows the QEMU main-loop thread to continue.

2022-03-02target/arm: Report KVM's actual PSCI version to guest in dtbPeter Maydell3-3/+15
When we're using KVM, the PSCI implementation is provided by the kernel, but QEMU has to tell the guest about it via the device tree. Currently we look at the KVM_CAP_ARM_PSCI_0_2 capability to determine if the kernel is providing at least PSCI 0.2, but if the kernel provides a newer version than that we will still only tell the guest it has PSCI 0.2. (This is fairly harmless; it just means the guest won't use newer parts of the PSCI API.) The kernel exposes the specific PSCI version it is implementing via the ONE_REG API; use this to report in the dtb that the PSCI implementation is 1.0-compatible if appropriate. (The device tree binding currently only distinguishes "pre-0.2", "0.2-compatible" and "1.0-compatible".)

2022-03-02target/arm: Implement FEAT_LPA2Richard Henderson4-15/+112
This feature widens physical addresses (and intermediate physical addresses for 2-stage translation) from 48 to 52 bits, when using 4k or 16k pages. This introduces the DS bit to TCR_ELx, which is RES0 unless the page size is enabled and supports LPA2, resulting in the effective value of DS for a given table walk. The DS bit changes the format of the page table descriptor slightly, moving the PS field out to TCR so that all pages have the same sharability and repurposing those bits of the page table descriptor for the highest bits of the output address. Do not yet enable FEAT_LPA2; we need extra plumbing to avoid tickling an old kernel bug.
