(In reply to Vanya Lazeev from comment #9) > Have you tried the attached patch? If not, could you do it? Hi, yes thanks, that patch seems to apply now on v5.2.1 and work in the same system as mentioned in comment #6
The above mentioned patch seems to apply and work as such in v5.0.21 as well, so that is good for possible backporting efforts. Patch is ok for v5.0 as well, but my fTPM didn't seem to work very well in that version, as if TPM would go to sleep frequently and not execute commands as expected.
I still see this problem against the master branch at 0be0ee71816b2b6725e2b4f32ad6726c9d729777 11 NOV 2019. And after installing the patch. /home/dgilson [dgilson@PWP 504]$dmesg | grep -i tpm [ 0.035005] ACPI: TPM2 0x000000007B7F9000 000034 (v03 INSYDE BDW-DE 00000000 ACPI 00040000) [ 28.074061] tpm_crb MSFT0101:00: can't request region for resource [mem 0x7b69b000-0x7b69b02f] [ 28.083703] tpm_crb: probe of MSFT0101:00 failed with error -16 [ 28.819778] ima: No TPM chip found, activating TPM-bypass! /home/dgilson [dgilson@PWP 503]$sudo cat /proc/iomem sudo: unable to resolve host PWP 00000000-00000fff : Reserved 00001000-0007ffff : System RAM 00080000-0009ffff : Reserved 000a0000-000bffff : PCI Bus 0000:00 000c0000-000c7fff : Video ROM 000f0000-000fffff : System ROM 00100000-676fefff : System RAM 57e00000-58c00e50 : Kernel code 58c00e51-5964bb7f : Kernel data 598e6000-59dfffff : Kernel bss 676ff000-679fefff : Unknown E820 type 679ff000-6f02efff : Reserved 6ae45018-6ae4506f : APEI ERST 6ae45070-6ae47017 : APEI ERST 6f02f000-7b69efff : ACPI Non-volatile Storage 7b69f000-7b7fefff : ACPI Tables 7b7ff000-7b7fffff : System RAM 7b800000-7bffffff : RAM buffer 80000000-8fffffff : PCI MMCONFIG 0000 [bus 00-ff] 80000000-8fffffff : Reserved 90000000-fbffbfff : PCI Bus 0000:00 91000000-920fffff : PCI Bus 0000:0a 91000000-920fffff : PCI Bus 0000:0b 91000000-91ffffff : 0000:0b:00.0 92000000-9201ffff : 0000:0b:00.0 92100000-921fffff : PCI Bus 0000:02 92100000-92101fff : 0000:02:00.0 92100000-92101fff : ioatdma 92102000-92103fff : 0000:02:00.1 92102000-92103fff : ioatdma 92104000-92105fff : 0000:02:00.2 92104000-92105fff : ioatdma 92106000-92107fff : 0000:02:00.3 92106000-92107fff : ioatdma 92200000-926fffff : PCI Bus 0000:03 92200000-923fffff : 0000:03:00.1 92200000-923fffff : ixgbe 92400000-925fffff : 0000:03:00.0 92400000-925fffff : ixgbe 92600000-92603fff : 0000:03:00.1 92600000-92603fff : ixgbe 92604000-92607fff : 0000:03:00.0 92604000-92607fff : ixgbe 92680000-926fffff : 0000:03:00.0 92700000-92afffff : PCI Bus 0000:03 92700000-927fffff : 0000:03:00.1 92800000-928fffff : 0000:03:00.1 92900000-929fffff : 0000:03:00.0 92a00000-92afffff : 0000:03:00.0 92b00000-92b0ffff : 0000:00:14.0 92b00000-92b0ffff : xhci-hcd 92b10000-92b107ff : 0000:00:1f.2 92b10000-92b107ff : ahci 92b11000-92b113ff : 0000:00:1d.0 92b11000-92b113ff : ehci_hcd 92b12000-92b123ff : 0000:00:1a.0 92b12000-92b123ff : ehci_hcd 92b13000-92b130ff : 0000:00:1f.3 92b14000-92b1400f : 0000:00:16.0 92b15000-92b1500f : 0000:00:16.1 92b16000-92b16fff : 0000:00:05.4 fbffc000-fbffcfff : dmar0 feb00000-feb03fff : Reserved fec00000-fec00fff : Reserved fec00000-fec003ff : IOAPIC 0 fec01000-fec013ff : IOAPIC 1 fed00000-fed003ff : HPET 0 fed00000-fed003ff : PNP0103:00 fed18000-fed19fff : Reserved fed1c000-fed1ffff : Reserved fed1c000-fed1ffff : pnp 00:04 fed1f800-fed1f9ff : intel-spi fed20000-fed3ffff : pnp 00:04 fed40000-fed44fff : MSFT0101:00 fed90000-fed93fff : pnp 00:04 fee00000-feefffff : pnp 00:04 fee00000-fee00fff : Local APIC ff000000-ffffffff : INT0800:00 ff800000-ffffffff : Reserved 100000000-27fffffff : System RAM /home/dgilson [dgilson@PWP 505]$sudo cat /proc/iomem | grep -i 7b7f sudo: unable to resolve host PWP 7b69f000-7b7fefff : ACPI Tables 7b7ff000-7b7fffff : System RAM acpidump TPM2 @ 0x0000000000000000 0000: 54 50 4D 32 34 00 00 00 03 90 49 4E 53 59 44 45 TPM24.....INSYDE 0010: 42 44 57 2D 44 45 00 00 00 00 00 00 41 43 50 49 BDW-DE......ACPI 0020: 00 00 04 00 00 00 00 00 00 B0 69 7B 00 00 00 00 ..........i{.... 0030: 02 00 00 00 ....
