2023-01-23virtio-blk: simplify virtio_blk_dma_restart_cb()Stefan Hajnoczi
virtio_blk_dma_restart_cb() is tricky because the BH must deal with virtio_blk_data_plane_start()/virtio_blk_data_plane_stop() being called. There are two issues with the code: 1. virtio_blk_realize() should use qdev_add_vm_change_state_handler() instead of qemu_add_vm_change_state_handler(). This ensures the ordering with virtio_init()'s vm change state handler that calls virtio_blk_data_plane_start()/virtio_blk_data_plane_stop() is well-defined. Then blk's AioContext is guaranteed to be up-to-date in virtio_blk_dma_restart_cb() and it's no longer necessary to have a special case for virtio_blk_data_plane_start(). 2. Only blk_drain() waits for virtio_blk_dma_restart_cb()'s blk_inc_in_flight() to be decremented. The bdrv_drain() family of functions do not wait for BlockBackend's in_flight counter to reach zero. virtio_blk_data_plane_stop() relies on blk_set_aio_context()'s implicit drain, but that's a bdrv_drain() and not a blk_drain(). Note that virtio_blk_reset() already correctly relies on blk_drain(). If virtio_blk_data_plane_stop() switches to blk_drain() then we can properly wait for pending virtio_blk_dma_restart_bh() calls. Once these issues are taken care of the code becomes simpler. This change is in preparation for multiple IOThreads in virtio-blk where we need to clean up the multi-threading behavior. I ran the reproducer from commit 49b44549ace7 ("virtio-blk: On restart, process queued requests in the proper context") to check that there is no regression.

2023-01-23util/aio: Defer disabling poll mode as long as possibleChao Gao
When we measure FIO read performance (cache=writethrough, bs=4k, iodepth=64) in VMs, ~80K/s notifications (e.g., EPT_MISCONFIG) are observed from guest to qemu. It turns out those frequent notificatons are caused by interference from worker threads. Worker threads queue bottom halves after completing IO requests. Pending bottom halves may lead to either aio_compute_timeout() zeros timeout and pass it to try_poll_mode() or run_poll_handlers() returns no progress after noticing pending aio_notify() events. Both cause run_poll_handlers() to call poll_set_started(false) to disable poll mode. However, for both cases, as timeout is already zeroed, the event loop (i.e., aio_poll()) just processes bottom halves and then starts the next event loop iteration. So, disabling poll mode has no value but leads to unnecessary notifications from guest. To minimize unnecessary notifications from guest, defer disabling poll mode to when the event loop is about to be blocked. With this patch applied, FIO seq-read performance (bs=4k, iodepth=64, cache=writethrough) in VMs increases from 330K/s to 413K/s IOPS.

2023-01-23target/arm: Look up ARMCPRegInfo at runtimeRichard Henderson
Do not encode the pointer as a constant in the opcode stream. This pointer is specific to the cpu that first generated the translation, which runs into problems with both hot-pluggable cpus and user-only threads, as cpus are removed. It's also a potential correctness issue in the theoretical case of a slightly-heterogenous system, because if CPU 0 generates a TB and then CPU 1 executes it, CPU 1 will end up using CPU 0's hash table, which might have a wrong set of registers in it. (All our current systems are either completely homogenous, M-profile, or have CPUs sufficiently different that they wouldn't be sharing TBs anyway because the differences would show up in the TB flags, so the correctness issue is only theoretical, not practical.) Perform the lookup in either helper_access_check_cp_reg, or a new helper_lookup_cp_reg.

Qemu doesn't implement Debug Communication Channel, as well as the rest of external debug interface. However, Microsoft Hyper-V in tries to access some of those registers during an EL2 context switch. Since there is no architectural way to not advertise support for external debug, provide RAZ/WI stubs for OSDTRRX_EL1, OSDTRTX_EL1 and OSECCR_EL1 registers in the same way the rest of DCM is currently done.

2023-01-23target/arm: Don't set EXC_RETURN.ES if Security Extension not presentPeter Maydell
In v7m_exception_taken(), for v8M we set the EXC_RETURN.ES bit if either the exception targets Secure or if the CPU doesn't implement the Security Extension. This is incorrect: the v8M Arm ARM specifies that the ES bit should be RES0 if the Security Extension is not implemented, and the pseudocode agrees. Remove the incorrect condition, so that we leave the ES bit 0 if the Security Extension isn't implemented. This doesn't have any guest-visible effects for our current set of emulated CPUs, because all our v8M CPUs implement the Security Extension; but it's worth fixing in case we add a v8M CPU without the extension in future.

PnvChipClass, PnvChip, Pnv8Chip, Pnv9Chip, and Pnv10Chip are defined in pnv.h. Many users of the header don't actually need them. One instance is this inclusion loop: hw/ppc/pnv_homer.h includes hw/ppc/pnv.h for typedef PnvChip, and vice versa for struct PnvHomer. Similar structs live in their own headers: PnvHomerClass and PnvHomer in pnv_homer.h, PnvLpcClass and PnvLpcController in pci_lpc.h, PnvPsiClass, PnvPsi, Pnv8Psi, Pnv9Psi, Pnv10Psi in pnv_psi.h, ...

2023-01-20hw/riscv/virt.c: move create_fw_cfg() back to virt_machine_init()Daniel Henrique Barboza
Commit 1c20d3ff6004 ("hw/riscv: virt: Add a machine done notifier") moved the initialization of fw_cfg to the virt_machine_done() callback. Problem is that the validation of fw_cfg by devices such as ramfb is done before the machine done notifier is called. Moving create_fw_cfg() to machine_done() results in QEMU failing to boot when using a ramfb device: ./qemu-system-riscv64 -machine virt -device ramfb -serial stdio qemu-system-riscv64: -device ramfb: ramfb device requires fw_cfg with DMA The fix is simple: move create_fw_cfg() config back to virt_machine_init(). This happens to be the same way the ARM 'virt' machine deals with fw_cfg (see machvirt_init() and virt_machine_done() in hw/arm/virt.c), so we're keeping consistency with how other machines handle this device.

The new helper always validates the contents of FRM, even if the new rounding mode is not DYN. This is required by the vector unit. Track whether we've validated FRM separately from whether we've updated fp_status with a given rounding mode, so that we can elide calls correctly. This partially reverts d6c4d3f2a69 which attempted the to do the same thing, but with two calls to gen_set_rm(), which is both inefficient and tickles an assertion in decode_save_opc.
