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.

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.

create_fdt_socket_cpus() writes a different 'mmu-type' value if we're running in 32 or 64 bits. However, the flag is being calculated during virt_machine_init(), and is passed around in create_fdt(), then create_fdt_socket(), and then finally create_fdt_socket_cpus(). None of the intermediate functions are using the flag, which is a bit misleading. Remove 'is_32_bit' flag from create_fdt_socket_cpus() and calculate it using the already available RISCVVirtState pointer. This will also change the signature of create_fdt_socket() and create_fdt(), making it clear that these functions don't do anything special when we're running in 32 bit mode.

The sifive_u, spike and virt machines are writing the 'bootargs' FDT node during their respective create_fdt(). Given that bootargs is written only when '-append' is used, and this option is only allowed with the '-kernel' option, which in turn is already being check before executing riscv_load_kernel(), write 'bootargs' in the same code path as riscv_load_kernel().

2023-01-20hw/riscv: write initrd 'chosen' FDT inside riscv_load_initrd()Daniel Henrique Barboza
riscv_load_initrd() returns the initrd end addr while also writing a 'start' var to mark the addr start. These informations are being used just to write the initrd FDT node. Every existing caller of riscv_load_initrd() is writing the FDT in the same manner. We can simplify things by writing the FDT inside riscv_load_initrd(), sparing callers from having to manage start/end addrs to write the FDT themselves. An 'if (fdt)' check is already inserted at the end of the function because we'll end up using it later on with other boards that doesn´t have a FDT.

2023-01-20hw/riscv/boot.c: introduce riscv_default_firmware_name()Daniel Henrique Barboza
Some boards are duplicating the 'riscv_find_and_load_firmware' call because the 32 and 64 bits images have different names. Create a function to handle this detail instead of hardcoding it in the boards. Ideally we would bake this logic inside riscv_find_and_load_firmware(), or even create a riscv_load_default_firmware(), but at this moment we cannot infer whether the machine is running 32 or 64 bits without accessing RISCVHartArrayState, which in turn can't be accessed via the common code from boot.c. In the end we would exchange 'firmware_name' for a flag with riscv_is_32bit(), which isn't much better than what we already have today.
