Tao Yuhong	996e8f680c	HV: pci-vuart support create vdev hcall ... Add cteate method for vmcs9900 vdev in hypercalls. The destroy method of ivshmem is also suitable for other emulated vdev, move it into hcall_destroy_vdev() for all emulated vdevs Tracked-On: #5394 Signed-off-by: Tao Yuhong <yuhong.tao@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com>	2020-10-30 20:41:34 +08:00
Tao Yuhong	691abe90ff	HV: vuart: send msi for pci vuart type ... if vuart type is pci-vuart, then use MSI interrupt split vuart_toggle_intr() control flow into vuart_trigger_level_intr() & trigger_vmcs9900_msix(), because MSI is edge triggered, no deassertion operation. Only trigger MSI for pci-vuart when assert interrupt.

Tao Yuhong	55b7fae67a	HV: pci-vuart: pci based vuart emulation ... Add emulation for pci based vuart device mcs9900 at hv land. add struct pci_vdev_ops vuart_pci_ops, the vdev callbalks for vuart. How to use In misc/vm_configs/scenarios/<SCENARIO>/<BOARD>/pci_dev.c, add pci vuart config to vm_pci_devs[] array. For example: struct acrn_vm_pci_dev_config vm0_pci_devs[] = { /* console vuart setting*/ { .emu_type = PCI_DEV_TYPE_HVEMUL, .vbdf.bits = {.b = 0x00U, .d = 0x04U, .f = 0x00U}, .vdev_ops = &vmcs_ops, .vbar_base[0] = 0x80001000, /* mmio bar */ .vbar_base[1] = 0x80002000, /* msix bar */ .vuart_idx = 0, }, /* communication vuart setting */ { .emu_type = PCI_DEV_TYPE_HVEMUL, .vbdf.bits = {.b = 0x00U, .d = 0x05U, .f = 0x00U}, .vdev_ops = &vmcs_ops, .vbar_base[0] = 0x80003000, .vbar_base[1] = 0x80004000, .vuart_idx = 1, .t_vuart.vm_id = 1U, .t_vuart.vuart_id = 1U, }, } Tracked-On: #5394 Signed-off-by: Tao Yuhong <yuhong.tao@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com> Acked-by: Eddie Dong <eddie.dong@Intel.com>	2020-10-30 20:41:34 +08:00
