julien M <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #9 from julien M <[email protected]> --- Having the same issue here with: FreeBSD 12.0-STABLE r349117 GENERIC amd64 (Generic kernel WITH xhci support) I patched stable with revisions 348778 and 348779 + D20623. FIRST TRY (vm create + vm install): BEFORE installing Ubuntu 18.04 on Bhyve: $ pciconf -r ppt4 0x3f 145c1022 00100007 0c033000 00800010 d9b00004 00000000 00000000 00000000 00000000 00000000 00000000 50071458 00000000 00000048 00000000 00000325 AFTER REBOOT: $ pciconf -r ppt4 0x3f 145c1022 00100407 0c033000 00800010 d9b00004 00000000 00000000 00000000 00000000 00000000 00000000 50071458 00000000 00000048 00000000 00000325 CHANGES: 00100007 => 00100407 SECOND TRY (vm destroy, vm create, vm install): AFTER issuing: vm install linux linux.iso (while ubuntu is installing): $ pciconf -r ppt4 0x3f 145c1022 10100407 0c033000 00800010 d9b00004 00000000 00000000 00000000 00000000 00000000 00000000 50071458 00000000 00000048 00000000 00000325 CHANGES: 00100407 => 10100407 THIRD TRY (vm destroy, vm create, vm install): AFTER issuing: vm install ...: $ pciconf -r ppt4 0x3f 145c1022 10100407 0c033000 00800010 d9b00004 00000000 00000000 00000000 00000000 00000000 00000000 50071458 00000000 00000048 00000000 00000325 CHANGES: NONE It seems that the FIRST install is breaking everything by changing 00100007 to 00100407. After a FreeBSD reboot, the 00100007 is back and passthrough is working when installing for the FIRST time linux in bhyve. This is the device to be passed: ppt2@pci0:8:0:0: class=0x130000 card=0x145a1022 chip=0x145a1022 rev=0x00 hdr=0x00 vendor = 'Advanced Micro Devices, Inc. [AMD]' device = 'Zeppelin/Raven/Raven2 PCIe Dummy Function' class = non-essential instrumentation ppt3@pci0:8:0:2: class=0x108000 card=0x14561022 chip=0x14561022 rev=0x00 hdr=0x00 vendor = 'Advanced Micro Devices, Inc. [AMD]' device = 'Family 17h (Models 00h-0fh) Platform Security Processor' class = encrypt/decrypt ppt4@pci0:8:0:3: class=0x0c0330 card=0x50071458 chip=0x145c1022 rev=0x00 hdr=0x00 vendor = 'Advanced Micro Devices, Inc.

I might be able to test this configuration in FreeBSD-CURRENT if that's of any help? (compile times are low on a threadripper 1950x). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
