Subject: [Qemu-devel] [PATCH for-2.6 v2 0/2] acpi: tpm: "Fix" TPM ACPI description
Date: Fri, 8 Apr 2016 13:23:12 +0200

TPM used to 'work', since in commit:
  711b20b4 Add ACPI tables for TPM
as TPM device has been placed outside of PCI0 bus scope
with IRQ commented out, but since commit
  5cb18b3d TPM2 ACPI table support
with following fixup
  9e472263 acpi: add missing ssdt
it has been moved to correct ISA bus scope,
however no one added MMIO resource to parent bus
and IRQ(5) became uncommented which regressed
TPM as Windows fails to init it due to lack of resources
  'device cannot find enough free resources'

Series is a partialy fix and a partially hack to
temporary make TPM work on Windows.
 1/2 - fixes IO resource lack on parent bus
 2/2 - temporary comment out IRQ description
       to make Windows beleve that there isn't
       any possible conflict to force successful
       driver initialization

Tested with Windows 8.1x64

Igor Mammedov (2):
  pc: acpi: tpm: add missing MMIO resource to PCI0._CRS
  tpm: acpi: remove IRQ from TPM's CRS to make Windows not see conflict
