https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239341 Bug ID: 239341 Summary: HDA support doesn't work for me Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: shamaz.mazum@gmail.com Created attachment 205930 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D205930&action= =3Dedit Patch that fixes the problem for me Hello. I am running FreeBSD 12.0-RELEASE and want to try hda (audio) suppor= t, which was added to CURRENT recently (base r349335). So I have cherry-picked that commit (I use git mirror on github) and rebuilt bhyve. When I add HDA device, bhyve aborts on assertion: root@vonbraun:~ # bhyve -c 1 -m 2G -w -H -s 0,hostbridge -s 4,ahci-cd,/home/vasily/Fedora-Workstation-Live-x86_64-30-1.2.iso -s 6,hda,play=3D/dev/dsp -s 29,fbuf,tcp=3D127.0.0.1:5900,w=3D1920,h=3D1080 -s 30,xhci,tablet -s 31,lpc -l com1,stdio -l bootrom,BHYVE_UEFI.fd fedora (Fedora is booting. Some messages skipped.) Assertion failed: (!err), function hda_set_sdctl, file /usr/src/usr.sbin/bhyve/pci_hda.c, line 1072. Here are the last lines is bhyve_hda.log: hda_set_sdctl-1063: stream_ind: 0x4 old: 0x50001c value: 0x50001e hda_stream_start-677: stream: 0x4 bdl_cnt: 0x3 bdl_paddr: 0x773c5000 hda_stream_start-706: Fail to get the guest virtual address So I have examined pci_hda.c and discovered that bdle pointer in hda_stream_start function is shifted by 4 bytes from actual position of that structure in memory. I cannot explain it, but the following patch fixes the problem. Maybe it's because I did not rebuild the whole system, but maybe i= t's a bug in bhyve. Please tell me is HDA support work on your machine. --=20 You are receiving this mail because: You are the assignee for the bug.=
