Hi. As I posted about a week ago. I had an issue with an AMD FX-8350/Radeon 7970/Gigabyte GA-970A-UD3 and still do. After passing through the 7970, it works just fine on windows 10 for as long as I do not reboot/shutdown that VM. Upon shutting down or rebooting the VM whole system becomes unresponsive. A full reboot of Dom0 is required in order to get passthrough working again without a system crash. Someone suggested me to purchase a PCI serial card and I did. I can get linux serial console working without any issue including login via that console. As soon as I enable XEN hvc0 in kernel boot params all I get is VGA console output though I did not enabled it via XEN boot params. A working one: GRUB_CMDLINE_LINUX="console=tty0 console=ttyS1,115200n81". A non working one: GRUB_CMDLINE_LINUX="console=hvc0" as suggested at http://wiki.xen.org/wiki/Xen_Serial_Console dmesg | grep ttyS serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:04: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 0000:03:07.0: ttyS1 at I/O 0xc120 (irq = 21) is a 16550A --> Is a PCI serial card GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=4096M,max:8192M dom0_max_vcpus=4 dom0_vcpus_pin iommu=1 loglvl=all guest_loglvl=all com1=115200,8n1,0xc120,21 console=com1" Wit the above line I only get non-readable output. I tried it pretty much all way around including different RTS/CTS options and 3 different tools and the result was always non-readable output xl dmesg Xen 4.4.3 (XEN) Xen version 4.4.3 (root@) (gcc (Debian 4.7.2-5) 4.7.2) debug=n Mon Aug 31 21:00:13 EEST 2015 (XEN) Latest ChangeSet: Thu Aug 20 16:19:38 2015 +0200 git:27b82b0 (XEN) Bootloader: GRUB 1.99-27+deb7u2 (XEN) Command line: placeholder dom0_mem=4096M,max:8192M dom0_max_vcpus=4 dom0_vcpus_pin iommu=1 loglvl=all guest_loglvl=all (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: V2; EDID transfer time: 1 seconds (XEN) Disc information: (XEN) Found 5 MBR signatures (XEN) Found 5 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 000000000009e800 (usable) (XEN) 000000000009e800 - 00000000000a0000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 00000000be3ee000 (usable) (XEN) 00000000be3ee000 - 00000000be41e000 (reserved) (XEN) 00000000be41e000 - 00000000be42e000 (ACPI data) (XEN) 00000000be42e000 - 00000000be81b000 (ACPI NVS) (XEN) 00000000be81b000 - 00000000bedcd000 (reserved) (XEN) 00000000bedcd000 - 00000000bedce000 (usable) (XEN) 00000000bedce000 - 00000000befd4000 (ACPI NVS) (XEN) 00000000befd4000 - 00000000bf44e000 (usable) (XEN) 00000000bf44e000 - 00000000bf7df000 (reserved) (XEN) 00000000bf7df000 - 00000000bf800000 (usable) (XEN) 00000000f8000000 - 00000000fc000000 (reserved) (XEN) 00000000fec00000 - 00000000fec01000 (reserved) (XEN) 00000000fec10000 - 00000000fec11000 (reserved) (XEN) 00000000fec20000 - 00000000fec21000 (reserved) (XEN) 00000000fed00000 - 00000000fed01000 (reserved) (XEN) 00000000fed61000 - 00000000fed71000 (reserved) (XEN) 00000000fed80000 - 00000000fed90000 (reserved) (XEN) 00000000fef00000 - 0000000100000000 (reserved) (XEN) 0000000100001000 - 0000000240000000 (usable) (XEN) ACPI: RSDP 000F0490, 0024 (r2 ALASKA) (XEN) ACPI: XSDT BE428068, 0054 (r1 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: FACP BE42D958, 00F4 (r4 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI Warning (tbfadt-0464): Optional field "Pm2ControlBlock" has zero address or length: 0000000000000000/1 [20070126] (XEN) ACPI: DSDT BE428150, 5806 (r2 ALASKA A M I 88 INTL 20051117) (XEN) ACPI: FACS BE815F80, 0040 (XEN) ACPI: APIC BE42DA50, 009E (r3 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: FPDT BE42DAF0, 0044 (r1 ALASKA A M I 1072009 AMI 10013) (XEN) ACPI: MCFG BE42DB38, 003C (r1 ALASKA A M I 1072009 MSFT 10013) (XEN) ACPI: HPET BE42DB78, 0038 (r1 ALASKA A M I 1072009 AMI 5) (XEN) ACPI: IVRS BE42DBB0, 00B8 (r1 AMD RD890S 202031 AMD 0) (XEN) System RAM: 8168MB (8364188kB) (XEN) No NUMA configuration found (XEN) Faking a node at 0000000000000000-0000000240000000 (XEN) Domain heap initialised (XEN) found SMP MP-table at 000fd7d0 (XEN) DMI 2.7 present.
