--- Comment #23 from Clint Street <[email protected]> --- (In reply to Dag-Erling Smørgrav from comment #22) You are correct this tunable does not exist, but what about the tunables below: sys/amd64/vmm/amd/amdvi_hw.c:83:TUNABLE_INT("hw.vmm.amdvi_enable", &amdvi_enable_user); sys/amd64/vmm/amd/amdvi_hw.c:90:TUNABLE_INT("hw.vmm.enable_iotlb", &amdvi_enable_iotlb); sys/amd64/vmm/amd/amdvi_hw.c:96:TUNABLE_INT("hw.vmm.amdvi.host_ptp", &amdvi_host_ptp); sys/amd64/vmm/amd/amdvi_hw.c:102:TUNABLE_INT("hw.vmm.amdvi.ptp_level", &amdvi_ptp_level); sys/amd64/vmm/amd/amdvi_hw.c:108:TUNABLE_INT("hw.vmm.amdvi.disable_io_fault", &amdvi_disable_io_fault); sys/amd64/vmm/amd/npt.c:60:TUNABLE_INT_FETCH("hw.vmm.npt.enable_superpage", &enable_superpage); sys/amd64/vmm/vmm.c:411: TUNABLE_INT_FETCH("hw.vmm.vmx.use_tpr_shadowing", sys/amd64/vmm/intel/vmx.c:842: TUNABLE_INT_FETCH("hw.vmm.vmx.cap.tpr_shadowing", sys/amd64/vmm/intel/vmx.c:865: TUNABLE_INT_FETCH("hw.vmm.vmx.use_apic_vid", sys/amd64/vmm/intel/vmx.c:868:TUNABLE_INT_FETCH("hw.vmm.vmx.cap.virtual_interrupt_delivery", sys/amd64/vmm/intel/vmx.c:896: TUNABLE_INT_FETCH("hw.vmm.vmx.use_apic_pir", sys/amd64/vmm/intel/vmx.c:899:TUNABLE_INT_FETCH("hw.vmm.vmx.cap.posted_interrupts", sys/amd64/vmm/intel/vmx.c:918:TUNABLE_INT_FETCH("hw.vmm.l1d_flush", &guest_l1d_flush); sys/amd64/vmm/intel/vmx.c:920:TUNABLE_INT_FETCH("hw.vmm.vmx.l1d_flush", &guest_l1d_flush); sys/amd64/vmm/intel/vmx.c:933:TUNABLE_INT_FETCH("hw.vmm.l1d_flush_sw", sys/amd64/vmm/intel/vmx.c:936:TUNABLE_INT_FETCH("hw.vmm.vmx.l1d_flush_sw", sys/amd64/vmm/intel/ept.c:102:TUNABLE_INT_FETCH("hw.vmm.ept.use_superpages", &use_superpages); sys/amd64/vmm/intel/ept.c:107:TUNABLE_INT_FETCH("hw.vmm.ept.use_hw_ad_bits", &use_hw_ad_bits); sys/amd64/vmm/intel/ept.c:114:TUNABLE_INT_FETCH("hw.vmm.ept.use_exec_only", &use_exec_only); Can I add these to the vmm manpage? I found the issue with my setup was that I had to replace vmm.ko from the directories /boot/modules and /boot/kernel in order to get it working. I have removed the enable_vtd tunable and GPU passthrough works with the patches from Corvin and by changing the hypervisor signature to "KVMKVMKVM\0\0\0". -- You are receiving this mail because: You are on the CC list for the bug.
