Harmening <j...@freebsd.org> --- Apologies for the delay, here are the (e)cap reports for all DMAR units on the system: Apr 7 19:01:39 corona kernel: dmar0: <DMA remap> iomem 0xbb7fc000-0xbb7fcfff on acpi0 Apr 7 19:01:39 corona kernel: dmar0: regs@0xbb7fc000, ver=4.0, seg=0, flags=<0> Apr 7 19:01:39 corona kernel: dmar0: cap=40780466<PLMR,PHMR,ZLR>,8ed008c<PSI,DWD,DRD,PSI>, ndoms=2, sagaw=4, mgaw=56, fro=64, nfr=1, superp=3, mamv=45 Apr 7 19:01:39 corona kernel: dmar0: ecap=f050df<C,QI,DI,IR,EIM,PT,SC>,600, mhmw=15, iro=80 Apr 7 19:01:39 corona kernel: dmar1: <DMA remap> iomem 0xd0ffc000-0xd0ffcfff on acpi0 Apr 7 19:01:39 corona kernel: dmar1: regs@0xd0ffc000, ver=4.0, seg=0, flags=<0> Apr 7 19:01:39 corona kernel: dmar1: cap=40780466<PLMR,PHMR,ZLR>,8ed008c<PSI,DWD,DRD,PSI>, ndoms=2, sagaw=4, mgaw=56, fro=64, nfr=1, superp=3, mamv=45 Apr 7 19:01:39 corona kernel: dmar1: ecap=f050df<C,QI,DI,IR,EIM,PT,SC>,600, mhmw=15, iro=80 Apr 7 19:01:39 corona kernel: dmar2: <DMA remap> iomem 0xe67fc000-0xe67fcfff on acpi0 Apr 7 19:01:39 corona kernel: dmar2: regs@0xe67fc000, ver=4.0, seg=0, flags=<0> Apr 7 19:01:39 corona kernel: dmar2: cap=40780466<PLMR,PHMR,ZLR>,8ed008c<PSI,DWD,DRD,PSI>, ndoms=2, sagaw=4, mgaw=56, fro=64, nfr=1, superp=3, mamv=45 Apr 7 19:01:39 corona kernel: dmar2: ecap=f050df<C,QI,DI,IR,EIM,PT,SC>,600, mhmw=15, iro=80 Apr 7 19:01:39 corona kernel: dmar3: <DMA remap> iomem 0xfb7fc000-0xfb7fcfff on acpi0 Apr 7 19:01:39 corona kernel: dmar3: regs@0xfb7fc000, ver=4.0, seg=0, flags=<0> Apr 7 19:01:39 corona kernel: dmar3: cap=40780466<PLMR,PHMR,ZLR>,8ed008c<PSI,DWD,DRD,PSI>, ndoms=2, sagaw=4, mgaw=56, fro=64, nfr=1, superp=3, mamv=45 Apr 7 19:01:39 corona kernel: dmar3: ecap=f050df<C,QI,DI,IR,EIM,PT,SC>,600, mhmw=15, iro=80 Apr 7 19:01:39 corona kernel: dmar4: <DMA remap> iomem 0xa5ffc000-0xa5ffcfff on acpi0 Apr 7 19:01:39 corona kernel: dmar4: regs@0xa5ffc000, ver=4.0, seg=0, flags=<1<INCLUDE_ALL_PCI>> Apr 7 19:01:39 corona kernel: dmar4: cap=40780466<PLMR,PHMR,ZLR>,8ed008c<PSI,DWD,DRD,PSI>, ndoms=2, sagaw=4, mgaw=56, fro=64, nfr=1, superp=3, mamv=45 Apr 7 19:01:39 corona kernel: dmar4: ecap=f050df<C,QI,DI,IR,EIM,PT,SC>,600, mhmw=15, iro=80 All appear to have the same capabilities, and all are coherent (dmar4 is the unit that hosts the NVMe drive) -- You are receiving this mail because: You are the assignee for the bug.
